[WIP] Anti-Bounce System (ABS)

This is a simple and lightweight addon that attempts to improve (not fix) the weird PhysX problem where the vehicles bounce up into the air upon contact.
All "Land" vehicles are supported (from any mod)


I made this addon for my upcoming AI mod, as they had a tendency to flip their vehicles a lot while driving. But I suppose it is worth using by players as well.

I have tried my best to make the vehicle movement look as natural as possible (basically no "teleporting"). There shouldn't be any undesirable side-effects (interference with normal vehicle physics)

Please note that the problem with PhysX cannot be fixed with a simple addon, because it is engine related. Also, please note that this mod is still work-in-progress, so do not use it in any serious missions until you've tested it and made sure it satisfies your needs.

I will try to improve the mod with your feedback, so please report all your issues and findings.


Attempts to prevent the vehicle from flying into the air upon contact, caused by sharp edges in geometries (which apparently impart a large moment to the vehicle, thus sending it up into the air). The vehicle cannot be stopped completely though (due to vehicle acceleration):

You can find one instance of this building about 800 m east of Stratis Airbase, next to the end of a road which you should be able to find easily (GRID: 025055). You can also place the building yourself (Land_i_Stone_Shed_V1_F)



Gives the vehicle a small "boost" to help it unflip. Note that it doesn't always work (especially if the vehicle is completely upside-down).
The vehicles get back on its tracks due to the boost (force) itself. It doesn't "teleport" to that position (setVectorUp or other dirty methods) .
The unflipping occurs while PhysX contact is in progress. So a perfectly still vehicle will not unflip.


Use WASD keys to unflip your vehicle.


Unbinding the WASD keys will disable this feature (see below)

Customize the mod features using CBA settings and keybindings.
CBA Settings: [Pause menu] -> Game -> Configure Addons -> Anti-Bounce System or [Pause menu] -> Addon Options -> Anti-Bounce System

CBA Keybindings: [Pause menu] -> Controls -> Configure Addons -> Anti-Bounce System

Extremely lightweight (event handler based) and nearly zero performance impact, so it is used on all land vehicles.

The mod should work fine in MP, but I haven't tested it yet.
It must be loaded by both the server and the clients.

This mod only triggers upon PhysX contact. If the vehicle is completely stationary for at least a few seconds, the PhysX contact stops and the vehicle cannot be unflipped automatically. In such cases, you can try shooting the vehicle (with a rifle or pistol) to trigger the PhysX contact. Hopefully that can make the vehicle unflip.

Please note that this mod is still work-in-progress (unfinished). The author neither claims nor guarantees that this mod will be completely harmless. Thus be sure to test the mod properly before using it in any serious operations/missions.
