How to get TModel impact force

[Arska134]

I just wanna know how i can get TModel impact force when two models collides. Can't found function for this one. :/

You can use the Collision Callback function of LE.In this function you can receive the force with which it collided.

 

void _stdcall EntityCollisionCallback( TEntity entity0, TEntity entity1, byte* position, byte* normal, byte* force, flt speed )

"Compile Error: Identifier 'entitycollisioncallback' not found"

 

I am using BlitzMax.

[macklebee]

did you set the collision call back with SetEntityCallback()?

Any little example about how to use SetEntityCallback() ?

[macklebee]

sure...

Import "c:\program files\leadwerks engine sdk\bmx\framework\framework.bmx"
RegisterAbstractPath(AppDir)

fw:TFramework = CreateFramework()
If Not  fw RuntimeError "Failed to initialize engine."
PositionEntity(fw.Main.Camera, Vec3(0, 1, - 4))

light:TLight = CreateDirectionalLight()
RotateEntity(light, Vec3(45, 45, 0))

drum:TModel = LoadModel("abstract::oildrum.gmf")

PositionEntity(drum, Vec3(0, 5, 0))

groundbody:TBody = CreateBodyBox(10, .1, 10)
EntityType(groundbody, 1)
groundmesh:TMesh = CreateCube(groundbody)
ScaleEntity(groundmesh, Vec3(10, .1, 10))
EntityColor(groundmesh, Vec4(.5, 0, .5, 1))

Collisions(1, 1, 1)

SetEntityCallback(drum, MyCallBack, ENTITYCALLBACK_COLLISION)

Repeat
If KeyHit(KEY_ESCAPE) Exit
       If AppTerminate() Exit

If KeyHit(KEY_SPACE)
	PositionEntity(drum, Vec3(Rand(0, 3), Rand(1, 8), Rand(0, 3)))
	RotateEntity(drum, Vec3(Rand(0, 90), Rand(0, 90), Rand(0, 90)))
End If

 	fw.Update()
  	fw.Render()

  	Flip(1)

Forever
GCCollect()
