I changed the size of the cube in the function

Code: Select all

NewtonCube *CGame::MakeCube(vector3df loc, vector3df veloc)

.
The size is now

Code: Select all

	// Create a box primitive. 38 is just an estimated value of the size of the model,
	float x = 4 * IrrToNewton;
	float y = 4 * IrrToNewton;
	float z = 8 * IrrToNewton;
	NewtonCollision* collision;
	collision = NewtonCreateBox(nWorld, x, y, z, NULL);

But the object will fall through the floor and wall more than 6 times when you throw it 10 times...
Is the model too small so he doesn't see the collision?

I doubt Newton would have that problem, but I have no idea what else it could be, providing you level geometry was fed in correctly. I suggest you post this on the Newton forum if your sure there's no mistake in any of your code.

The object is too small for the engine

Did you updated Ixx Iyy Izz factors according to your new size?

I read that thread on the Newton forum, and I must admit I'm surprised that the engine cares about size. Relative size maybe, but assuming that the size of the triangles in whatever your using for world geometry aren't too huge compared to the object, I find it dissapointing that Newton has a problem with the size.
