2d & 3D sound System, Implemented in engine and editor. with OpenAL & Fmod APIs. we can put 3d sounds, just like the other objects to scene .
Finally we decided, to Not using Nvidia PhysX In This Game. so we wrote our own Trigger System. Here there is a Simple Shot From this new Feature. and we can capture, each Trigger’s Events (OnEnter & OnExit , etc …) in Script, so we can do what ever we want. following shots demonstrates it.
here you can see very simple scene with some particle systems.
