[Not a Bug]TV Physics TV_EVENT_PHYSICSCOLLISION iBody2

[serial]

Code:

TV_EVENT_PHYSICSCOLLISION coll = pEngine.GetEventCollisionDesc(EventNumber);
Console.WriteLine(coll.iBody2.ToString());

As far as collision events go iBody2 seems to be return physics bodies that don't
even exist. 

For example I setup a landscape and the ID that is return is 17
int landID = pEngine.CreateStaticTerrainBody(land);

landID will equal 0.

Then I create a spherical phsyics body
int ballID = pEngine.CreateBody(1);
pEngine.AddMesh(ballID, ball, CONST_TV_PHYSICSBODY_BOUNDING.TV_BODY_SPHERE, true);

ballID will equal 17.

But coll.iBody2 returns 1.

If I reverse it(create the ball phsyics body first then the land physics body)  ballID will be 0, landId will be 1 and coll.iBody2 returns 2. 

I'm assuming iBody1 and iBody2 return the index of the physics bodies that collide.

If this is about TVLandscape and TVPhysics.CreateStaticTerrainBody, this actually isn't a bug. The TVPhysics.CreateStaticTerrainBody actually creates one Physics static body for overhead, then static one physics body for each chunk in the TVLandscape. So if you created the land with TVLandscape.GenerateTerrain("...", CONST_TV_LANDSCAPE_PRECISION...., 4, 4, ..., ..., ..., ...), that's 4 X 4 chunks, plus an overhead is 17 static physics bodies. You should also find that a collision should never occur with the overhead static physics body, 0 in this case (1 in the second case you've stated).

If it ever returns the overhead body, that might be a bug as that should not happen. Also note that creating a static physics body with a mesh should create only one static physics body with no overhead.

Thanks...That is what it was. Seems like checking for collision results between materials is a better way to get when it comes to landscapes.
