Hello! This one is a simple one, and contains mostly bugfixes to the reported problems with the previous tester's patch. However, I do want to talk about a feature that was recently (re)implemented.
For those that were seeing errors related to vehicle spawning, I'm most interested in hearing how it's working now. The vehicle spawn bugs were something I wasn't able to reproduce, but I do think that the changes I've made have improved it, hopefully enough to have fixed the problem.
Vehicle Inaccuracy
While mentioned in the patch notes, I forgot to call out that the vehicles have their "error" parameters reimplemented. In 0.9.1, following the vehicle rework, all vehicles became perfectly accurate regardless of what their accuracy was set to in the files.
This resulted in APCs and machineguns taking more than just pot-shots at passing planes, and anti-aircraft fire being dead on if you didn't jink or change speed. With this feature back in, only dedicated anti-aircraft weapons are accurate, and even those are no longer perfect unless you get close to them.
When taking fire from AAA, you should have a short warning to react to it before the distance is closed to the turret's effective range. This is back to how it was originally intended to work, and can be used to further differentiate different vehicles of the same type. E.g. a newer Shilka can be more accurate than a manually aimed older one.
For reference, this is how the system works:
Leading: Affects how far ahead or behind the AI can lead a target. Turrets which lack fire control software (e.g. machinegun turrets) will lag behind a moving target.
Effective Range: The range at which the turret will fire accurately onto a target. At ranges beyond this, accuracy falls off, and the turret will have some error applied to its targeting solution simulating an inaccurate solution.
Falloff Range/Error: At a certain range, the maximum amount of error that can be applied to a target. E.g. if set to 500m error at 1500m, this means that the most the targeting calculation will be off is by 500 meters when the target is 1500m away.
Min Height: Used mainly to prevent vehicles from firing into the ground when aiming at aircraft. For most vehicles this is irrelevant, but the ZSU-57-2 uses this to create the "flak floor" effect which prevents it from (purposefully) detonating flak too close to the ground.
Changelog
Improvements: - Tweaked empty shell color - More responsive radar/threat warning display auto ranging - Added 2 and 8 mile ranges for the displays
Bugfixes: - Delayed sounds waiitng to be played after scene has changed no longer crash - Fxied rare crash caused by bullet exploding the vehicle it was fired from if it impacts on its first frame - NavMeshAgent enabled only after initialization (should reduce log spam and make for cleaner vehicle spawning) - Simplified NavMesh spawning, and it now checks through a wider radius (hopefully reduces errors from spawning...) - Vehicles now avoid disabled/destroyed vehicles in addition to wrecks
0.9.2.1 is available on the Tester's branch!
Hello! The primary purpose of this patch is to migrate the aircraft guns/bullets to the new system used by the vehicles. This brings the optimizations and robustness from the vehicle weapons to the aircraft. For the most part this is a back end change, but in updating the code it has resulted in a lot of tangential features being updated.
This patch made some pretty large behind the scenes changes, so in the interest of stability I'd like to keep it on the tester's branch for a cycle or two.
ZSU-57-2
This patch brings in a new unit, the ZSU-57-2. This "flak tank" is primarily an area denial weapon. It's not very accurate, and cannot fire under a certain altitude, but if you get hit by a salvo it can be devastating. The ZSU-57-2 can be selected in the Strike Instant Action mode, and has been added to the Arena Demo.
Timed fuzes and flak
Vehicles can now be configured to fire an explosive round with a timed fuze. The new ZSU-57-2 fires these rounds. Flak rounds are explosive with a high splash damage, but aren't precisely aimed. The flak rounds of the ZSU-57-2 cannot explode below a minimum altitude, so they can be safely avoided by flying below the flak screens.
Changelog
New Features: - Many new visual and sound effects for the autocannon and cannon sized weaponry - Added ZSU-57-2 using a new timed fuze to create an area denial flak effect - Guns can use a timed fuze to explode based on a predicted target position - ZSU-57-2 has a "minimum engagement altitude" for turrets creates a "floor" that the player can fly under - Added ridiculous and extremely optimized empty shell system - Shilka, Mig-23, MiG-21, F-5E, and AV8B eject empty shells (I know the GAU-12 doesn't, but ¯\_(ツ)_/¯)
Improvements: - Aicraft guns migrated to new bullet/gun system - RecoilForce parameter moved to the gun itself - Vehicles override a gun's burst settings on the turret - Tracers have configurable length (1 for aircraft, 2 for vehicles) - All aircraft guns (even AI) now have bullet drop - AI can compensate correctly for bullet drop - Additional error reporting when something is wrong in the vehicle JSON - Revision of turret error properties + Leading is used to make the turret lag behind the target or apply extra lead + EffectiveRange is the range at which a turret is 100% accurate + FalloffError is the most a turret can be off target when the target is at or beyond FalloffRange + Offsetspeed changed such that higher values result in more errative behavior - Gun metal impact sounds more metalier, explosions more explosioner - Bigger muzzle flash for the Shilka
Bugfixes: - Vehicles/turrets no longer target destroyed/disabled vehicles - Fixed gun audio not playing correctly when firing - Aircraft guns won't continue fire sound or pause burst when put into nav mode while firing - Tracers appear correctly from the barrel, even on fast moving jets - More aircraft gun camera shake - Gun fire sound emitted from barrel rather than vehicle/aircraft center - Barrels recoil in the correct direction - Bullets spawn the specified effects on self-destruct/explosion - Fixed crazy issue where sometimes some gun sounds could only be heard if the camera was next to the control tower - Fixed vehicles being unable to target if there were too many vehicles around - Turrets no longer instantly reset to forward when they go idle - Tank muzzle flash smoke no longer turns with the barrel - Muzzle flash smoke now has shading applied correctly - Removed "HasRecoil" parameter, default barrel recoil is now 0 - Removed recoil visual from Shilka (not modelled correctly) - More (EXPERIMENTAL!) safeguards to help vehicles spawn without errors in Arena
Balance: - M60 top turret burst delay increased 2 -> 3 - Machineguns have difficulty tracking/leading moving targets - M163/Shilka have "perfect" accuracy only out to 1500m - All AAA in the Arena demo have had their build times increased to 70 seconds
0.9.1.1 Now Available! Features updated fire/smoke effects and bugfixes.
Hello! This patch was mainly for fixing bugs, but there's a few notable new features.
"Build Speed" lowers with the HP of strategic targets
This one was a suggestion that I think was pretty good. A base goes from 100% effectiveness to 0% effectiveness when it's destroyed, with nothing in between. This kind of binary state of a base made it feel like you weren't doing anything when you damaged a base, and further discouraged players from damaging a base if it was a target of opportunity. As before, a base has its critical structures restored when captured.
This goes both ways! Preventing your own bases from being damaged will make them harder to capture by virtue of being able to replace units quicker.
Visual refresh on smoke plumes in the battlefield
Another important change is the visual language for the smoke plumes. The original fire/smoke plume from damaged vehicles was a holdover from when much less of them were around. However, with the new and much more numerous vehicles, this old effect was causing huge smokestacks all over the map, often over inconsequential wreckages. Spammed like that, the effect lost its significance.
Now, big fire/smoke plume are reserved for damaged bases. It's a visual cue that a base is safer to attack, tells you exactly where the base is without needing any UI elements, and can't be confused for vehicles. Skirmishes between vehicles will still create smoke/fire, but it's more "smoldering field of wreckage" than "oil fire".
Changelog
New Features: - When structures are near destruction, they sometimes get set on fire - When a vehicle is destroyed, it enters a critical state before being fully destroyed - How long the vehicle is in the critical state depends on how much damage was done to it - After a vehicle has been critical for a short time, it will explode into a semi-permanent wreck
Improvements: - Strategic Target critical damage affects production rate of new groups down to a minimum of 10% - Vehicles have a new set of smaller fire/smoke effects when destroyed - GAU-12 fire sound (also used by Shilka and M163) has a more seamless loop - Shilka empty shells now in world space (won't turn with the turret) - Added chihirobelmo credit to the credits.txt for the smart scaling algorithm - Vehicles will defend closer to base radius (should prevent vehicles from driving to random beaches)
Bugfixes: - Many changes to FMOD audio stealing logic to prevent audio overlap and cutting out - Firing sound no longer persists after a Shilka stopped firing - Fixed bug where there was exactly a 1% chance that a vehicle could fail to spawn a wreck effect and NRE - Multi-barreled guns no longer create multiple unused audio sources - Friendly AV8Bs no longer error and get their logic stuck when encountering a Shilka - Running ther weapons camera on a munition which self-destructs no longer creates an error
0.9.0.7 - Vehicles, Pathfinding, and Supplies!
Hello! The 9.0.X patches are now public. This is the biggest patch the game has had in a while. In late June, I started working on IR SAMs. However, I quickly ran into many snags with regards to the performance and inflexibility of the current code. The bad news is that IR SAMs still aren't in. The good news is that the game has made some major strides forwards and cleared the worst roadblocks that used to keep me up at night.
For the moment, the Arena UI is really busy. I've added a shortcut to disable it, defaulting to Shift-H, while in flight, but this is all subject to change very soon.
Vehicle Overhaul
The central feature of this patch are the new vehicle mechanics and optimizations. The previous vehicle code struggled to scale any larger than what was presented in the Arena Demo mission. They also could not pathfind around obstacles, nor were they aware of terrain beyond that it existed below them. This critically lead to many limitations in the map design. For example, vehicles would be completely unaware of water, roads, mountains or bridges. The old vehicle code was also fundamentally quite performance intensive, even with many hacked on optimizations that made the code harder to understand and work on, to the point where I was simply not comfortable having more than ~100 active vehicles.
Pathfinding and its Implications
About 1800 lines of code later (and ~3700 deleted lines!), the vehicles have been massively overhauled, based on a proper pathfinding solution. It's hard to overstate how important this is to the game. From the beginning, I've wanted Tiny Combat Arena to be about strategically applying your own plane and weapons to influence a simulated battle on the ground. Your flights should be in service of a larger goal and mission, about more than just dogfighting in a context-less void. With this change, that goal feels totally within reach.
Vehicle behaviors are much more advanced now. They follow roads (and speed up when on them). They can travel through cities and around buildings. They will even try (try!) to avoid runways and drive around wreckages of other vehicles. This adds so much more depth to flexibility to how maps can be designed. The new code has been tested with hills, roads, canyons, and even tunnels. Vehicles will drive around bodies of water, and drive over bridges when available. Expect more interesting terrain soon!
In addition to all of this, the new code features greatly optimized code for bullets, guns, and turrets. The algorithms are efficient to the point where all vehicles can now compensate correctly for bullet drop, the targeting is much more accurate, and they can fire off many more shots than before without lagging the game. Vehicles can even support multiple turrets now (a forward looking feature). To show off this feature, the M60A1 is now able to use the commander's cupola machinegun.
This rewrite also gave me an opportunity to expose the bullet code to moddable JSON. Previously, guns could be edited, but the bullet definitions were hardcoded, optimized for the old gun system. The new guns were designed and optimized from the ground up to function with loaded data. However, be aware that these optimizations apply only to ground vehicles. Aircraft are still using the old gun/bullet system, but will converted soon enough.
Groups and Supplies
Vehicles are now spawned in groups rather than the gigantic and cumbersome formations. This gives more flexibility to how they move around the battlefield, and helps to spread the units out a bit more. Battles are a lot cooler to watch now!
Strategic Targets now have supplies and scenario defined group limits. Each base can support a certain number of groups of certain vehicle types. Strategic targets will automatically "build" new groups to hit their unit cap, and will replace groups that have been destroyed. Building is not instantaneous, though for the moment it is very quick.
Building vehicle groups costs supplies! Each group has a cost associated with it and if the strategic target expends all of its supplies it can no longer build units. Destroying units matters way more now that bases have supplies. If you destroy enough of their vehicles to run it out of supplies, those vehicles are gone forever. It makes vehicles much more valuable than before.
This system is something that will be expanded in due time, but for the moment, be aware that when a base is captured, it is automatically replenished up to 30 Supply. This is a feature I'm really excited about because it opens up many new avenues for mission design!
Revised View System
In order to expand the things that the camera can look at, there's been a slight rework on how views are selected.
External (F2), Chase (F3), Flyby (F4), and Weapon (F6) now only function to select cameras on the currently viewed object. Pressing F1 will always take you back to the cockpit of your plane and reset the viewed object to yourself.
Meanwhile, Vehicle (F7) and Aircraft (F8) can be used to cycle between all active vehicles and aircraft, setting them as the new viewed object. All the external cameras work on anything viewable, though the Weapon camera applies only to aircraft.
You can do the flyby camera on vehicles too, even if it looks a little silly.
Improved Targeting
The difficulty in targeting high threat targets is one of the game's most common criticisms, and something that's finally been addressed with this patch.
As you move the targeting crosshair around (hidden when looking forwards), a selection of 6 targets will be specially highlighted. Pressing the target button, the radar will cycle between these targets. Most importantly, this selection is prioritized by threat, so AAA like Shilkas will be targeted before a tank that is not a threat.
The targeting is based around the screen center, allowing you to target by looking at something. When off-boresight, a small crosshair will appear in the center of the screen to give you a reference point to aim with.
Flying Below Radar
Surprise new feature: you can fly below the radars of the Shilkas to avoid fire. This is probably temporary for this specific Shilka variant, since they are supposed to be horribly scary to try and kill at close range, but this is now a feature that can be applied to anything with radar. Keep in mind though that for the time being, this feature is only in use on the AAA radars. A pass on air to air combat, which will include refinement of the radar mechanics (and missiles), is still upcoming.
Closing Thoughts
What started as "I'm going to get SAMs working" ended up exposing the worst technical debt the game had. What's come out of the work, is a far more robust vehicle system and ground game that clears what was the biggest road block I feared. Maps are no longer extremely restrictive in design, vehicles are no longer the dramatic bottleneck of the game, and all the new mechanics create the building blocks that Arena needed to capture the feeling I was looking for.

0.9.0.6 is available on the tester's branch!
Hello! This is a small patch to get ready for the public release.
Changelog:

Version 0.9.0.5 is available on the Tester's Branch!
Hello! The finished version of the old prototype targeting work is finally in. I wanted to get this into the patch before it goes live, since the difficulty in targeting high threat targets is one of the game's most common criticisms.
The new Targeting
As you move the targeting crosshair around (hidden when looking forwards), a selection of 6 targets will be specially highlighted. Pressing the target button, the radar will cycle between these targets. Most importantly, this selection is prioritized by threat, so AAA like Shilkas will be targeted before a tank that is not a threat.
Anti-aircraft vehicles also now have a unique targeting icon to make it easier to pick them out.
It's worth mentioning again that the targeting is based around the screen center, allowing you to target by looking at something. When off-boresight, a small crosshair will appear in the center of the screen to give you a reference point to aim with.
Changelog:
New Features: - Added key (Shift-H by default) to toggle visibility of Arena symbology while flying
Improvements: - Targeting logic creates a group of selectable objects - Target button cycles between this group of objects - Selectable objects are prioritized by type so that threats are targeted first
Bugfixes: - Fixed bug where errors could be thrown by bullets when leaving Arena mode - Strela classified as SAM instead of vehicle
0.9.0.4 is on the Tester's branch!
Hello! The patch notes for this one are short, but there were some substantial under the hood changes.
Instant Action functionality has been restored. In particular, the Strike mode. The new vehicle code changed some pretty fundamental assumptions on how vehicles should work, so the Strike code needed to be adapted to work with these new systems. From a feature level, it should be identical, though the vehicles will pathfind a bit now, as opposed to before where they drove in a straight line to the target.
With this patch, the new vehicles are now on par with, or exceed all the features of the old vehicle code! If testing of this build goes well, it'll be pushed to live soon.
Changelog:
New Features: - Instant Action is functional again
Improvements: - In instant action, groups of vehicles are spawned in based on the faction defined formations - Removed ~3700 lines of old vehicle and vehicle adjacent code (no game change, but I'm really happy about it) - When a strategic target has negative MaxSupply, the UI will not show supply at all
Bugfixes: - Fixed group icon sometimes appearing at the origin for vehicles marked important (i.e. AAA)
0.9.0.3 is available on the Tester's branch!
What's New?
Hello! This is a small fix, but one I wanted to get out quickly because of the performance concerns.
The Database Viewer has been re-enabled, and has now been updated to use the new vehicle code.
More importantly though, if you played more than one Arena mission, the performance continue to degrade every time Arena was loaded. The brunt of this FPS drop was ironically felt in the Main Menu screen, but either way it worried me enough that I wanted to get a patch out to address it ASAP.
What's Next?
The next patch will focus on getting Instant Action Strike missions working again. This will require some level of redesign, or perhaps re-framing of what a "formation" is, and is used for. Vehicles spawn in and fight at the platoon level now instead of at the company level with sometimes mixed platoon types.
Changelog:
Improvements: - Database mode is re-enabled - Database shows statistics for multiple turrets (see M60A1) in a nicer format - Bullets are initialized only once on game startup - Drastically improved performance in the main menu
Bugfixes: - Added missing barrel to M1A1 that was preventing it from spawning - Missile turreted vehicles don't error check for barrels - SA-9 and SA-2 can spawn without errors again - Performance no longer sharply degrades after every level load - Bullet effects no longer play a SFX at the origin on game start
0.9.0.2 is on the Tester's Branch!
Hello and thank you for your patience! This was going to be a quick one-day hotfix but one thing led to another, turning it into something much more substantial.
Revised View System
In order to expand the things that the camera can look at, there's been a slight rework on how views are selected.
External (F2), Chase (F3), Flyby (F4), and Weapon (F6) now only function to select cameras on the currently viewed object. Pressing F1 will always take you back to the cockpit of your plane and reset the viewed object to yourself.
Meanwhile, Vehicle (F7) and Aircraft (F8) can be used to cycle between all active vehicles and aircraft, setting them as the new viewed object. All the external cameras work on anything viewable, though the Weapon camera applies only to aircraft.
You can do the flyby camera on vehicles too, even if it looks a little silly.
Improved Targeting
A prototype of a tweaked targeting system has made it in. The target that you will target next will be enlarged to the same size as a selected target, but not with the opacity of a selected target. This gives you some indication of what you will target next, as well as makes it more clear how the targeting system works.
When off-boresight, a small crosshair will appear that you can use to more clearly target something. Off-boresight targeting was already a feature, but I think most didn't know about it because the targeting logic was so opaque.
Flying Below Radar
Surprise new feature: you can fly below the radars of the Shilkas to avoid fire. This is probably temporary for this specific Shilka variant, since they are supposed to be horribly scary to try and kill at close range, but this is now a feature that can be applied to anything with radar. Keep in mind though that for the time being, this feature is only in use on the AAA radars. A pass on air to air combat, which will include refinement of the radar mechanics (and missiles), is still upcoming.
I'd also like to take this time to remind people that there is a radar altimeter under the normal barometric one which appears at low altitude. To fly under the Shilka's radar, you'll want to be around 150 feet AGL or lower!
Defensive Posture and Scenario Balancing
The previous patch had little regard to balancing put into it, so some corrections have been made. The largest of which is that vehicles can now adopt a defensive posture. When defending, vehicles will place themselves near a base, but position themselves such that they'll block an avenue of attack. Some vehicle groups have been reassigned to defend, while new defensive groups have been added to other bases.
This alone will help to curb a lot of the difficulty as the AI (anti-aircraft in particular!) won't be so hyper-aggressive at attacking bases. All the AAA are now defensive as they were originally intended to be. It's been lightened in the middle of the map, but the final objective still has two groups of Shilkas to contend with.
Vehicles will also now avoid wreckages, which can result in some interesting scenarios where a road gets so cluttered with wrecks that the vehicles will start to avoid the road entirely.
Some thoughts on balance and difficulty
I actually really enjoyed the previous patch's balance! While I understand it was difficult, what it really showed me is that not only can the game scale in difficulty but it scales in the way I originally intended it to. The mission was still winnable, but it required that you be on top of what was happening on a strategic level, and to make very key and pointed attacks with specialized weapons to cripple fronts. As some guy once said, you have to read the tide of battle.
Since AI travel along roads (though they might avoid them now if they get too bombed out!), you could totally cripple an offensive with a well aimed cluster bomb run. Destroying the Shilkas was of utmost importance, and with some fancy flying you can get close enough to gun them down, or plink at them from a distance with Mavericks if you prefer. If you didn't, they would be knocking at your doorstep and there's nothing you can do, making their destruction (or of their source) a top priority.
On some level, I'm a bit sad to be slightly nerfing the Shilkas and making the mission easier, but in due time there will be a campaign and multiple missions for which these things can be designed and balanced around. It was so encouraging to see that all come together in my recent playthroughs of the game, and I can't wait to start adding larger and more robust maps.

0.9.0.1 is on the Tester's Branch!
Hello! This was a long time coming and represents some very major milestones in the game's development. For a quick recap of what's been happening, read check out the previous news post regarding vehicles.
Until all features are restored, these new features are restricted to the TESTERS BRANCH of the game. Due to recent code changes, ONLY ARENA IS ACCESSIBLE IN THIS BUILD. Instant Action and Database have been temporarily disabled. For more information on how to access the tester's branch, see this Steam news post.
In addition to the features mentioned in the vehicles Steam news post, another major change and addition is how vehicles are spawned into Arena.
Groups and Supplies
Vehicles are now spawned in groups rather than the gigantic and cumbersome formations. This gives more flexibility to how they move around the battlefield, and helps to spread the units out a bit more. Battles are a lot cooler to watch now!
Strategic Targets now have supplies and scenario defined group limits. Each base can support a certain number of groups of certain vehicle types. Strategic targets will automatically "build" new groups to hit their unit cap, and will replace groups that have been destroyed. Building is not instantaneous, though for the moment it is very quick.
Building vehicle groups costs supplies! Each group has a cost associated with it and if the strategic target expends all of its supplies it can no longer build units. Destroying units matters way more now that bases have supplies. If you destroy enough of their vehicles to run it out of supplies, those vehicles are gone forever. It makes vehicles much more valuable than before.
Testers Branch means there will be bugs!
As stated above, ONLY ARENA IS ACCESSIBLE IN THIS BUILD. There's also a few things that are going to be a bit rough in this build, as the vehicle changes are not quite done yet.
The Arena UI is currently very busy. The way strategic targets are represented, along with much of the Arena UI, will be getting a pass once the vehicle work is finished as it is in a placeholder state.
Balance is going to be pretty wonky. Right now the mission is designed more around testing features than being very balanced. Many vehicles, tanks in particular, got some pretty big stats changes, so how they fit into combat has shifted.
The AI for vehicles is about halfway there. The capture AI shouldn't all try to converge on one point, and the attack AI should do a better job of seeking out targets. The AI should also spread out more when in combat rather than clump up on the roads. These are all known issues and are planned to be fixed.
Vehicles with machineguns (AAA and APCs) are actually a lot more accurate than they should be, due to some unimplemented code, but I kind of like it.
Share your Feedback!
I'm very curious to hear you all's thoughts on how this affects the flow of the game, and what you think can be improved.
This moves the game much closer to my original goal of the player's main mission being to support and influence the ground battles, so I'm very excited with where this will go now that maps can get a lot more interesting. These new mechanics also open the door to some interesting ideas that I plan on exploring such as supply convoys to replenish supplies.
Changelog
New Features: - New navmesh driven vehicles - Vehicles will prefer roads when out of Combat - Vehicles can navigate around fixed obstacles such as buildings - Completely new turret code for vehicles - Vehicles can now have multiple turrets - Completely new bullet code (used only by vehicles at the moment) - Bullets created and loaded through JSON data, exposing them for editing - Bullet constants file defines pools for different types of bullets and effects - Bullets and their visual effects pooled in a new, less disruptive way - Sensors are added to the vehicle, not the turret - Individual turrets can now be linked to specific sensors on the vehicle - Added error messages when spawning vehicles with invalid weapon or bullet names - Added error messages for invalid barrel and firepoint subparts, or turrets with no barrels - Navmesh support for "Sand Island" map - Buildings have built in "no go" navmesh option - Bridges default to "road" navmesh - Vehicles now operate in "Groups" instead of massive formations - Strategic Targets can support a scenario defined number of Groups - Groups are "built" one at a time, and require supplies to build - Strategic Target icons show group and "construction" related information - Strategic Targets can be run out of supplies to prevent spawning of new vehicles - When a strategic target is destroyed, its supplies are destroyed with it - If a Strategic Target has <5 supply on capture, it will get 5 supplies for free - Vehicle groups in combat will slow down to fire on the move and try to avoid roads - Vehicles further from camera run at reduced tick rates to allow for higher vehicle counts - "IsImportant" flag used on vehicles that require full fidelity regardless of distance (e.g. AAA)
Improvements: - Vehicle movement has been significantly optimized - Vehicles no longer clip into and overlap each other - Bullets and their visual effects should no longer produce intermittent stuttering - JSON: Renamed TurretBase->TurretAzimuth and Barrels->TurretElevation - JSON: Explicitly defined Barrel data now required for turrets - Significantly optimized targeting calculations allow for all vehicles to use bullets with gravity - Tank cannons now named after their real cannons - New visual effects for all machinegun impact types (Hit, Penetrate, Water, Grass, Explode) - Crater counts adjusted (Small 175->100, Medium 75->150) - Machineguns can not be heard from as far away - Cannons can be heard from further away - Bullet flyby SFX completely redone - Longer tracers - Targeting priorities are now specified on the turret level - Max range and targeting priorities of a vehicle moved to the turrets in the Database - Dust trail effect tweaked for performance - JSON: BurstLength now refers to how many shots per burst rather than a time interval - Vehicles wiggle a bit when off-road to simulate suspension - Aircraft guns use new impact SFX - Garbage collection optimizations for the old style bullets (still in use by aircraft) - Capturing of Stratgic Targets now happens in smooth "real time" versus one second "ticks" - Experimental incremental garbage collection enabled
Balance: - Fixed scaling options not applied to wreckages - M60A1 has a functional machinegun turret on top of its main turret - Machineguns no longer use thick bullets - Tank shell velocity more closely matches their real stats (1500-1700 m/s depending on gun) - M68 mounted on M1 is more accurate than the standard one mounted on the M60 - T80B has its own more powerful gun and projectile (2A46-2, 125mm)
Bugfixes: - Planar shadows render correctly for scaled buildings (i.e. bridges) - Bullets fired from AAA will no longer disappear when the vehicle is destroyed - Looping gun audio works correctly for vehicles (affected M163 and Shilka) - Ocean shader uses same depth offset as terrain - M1A1 has a proper barrel submesh for recoiling barrel animation - Potential fix for the elusive CAP null reference error that would shut down a flight of jets
