(C++) Bullet - Shortest code snippet ever!

[BlindSide]

Just thought I'd share this:

Code: Select all

btCompoundShape* cShape = new btCompoundShape();

for(u32 i = 0;i < meshBufferCount;++i)
{
		IMeshBuffer* mb = mesh->getMeshBuffer(i);
		cShape->addChildShape(btTransform::getIdentity(), 
			new btConvexHullShape(&((S3DVertex*)mb->getVertices())->Pos.X,
			mb->getVertexCount(), getVertexPitchFromType(mb->getVertexType())));	
}	

This short snippet will turn any Irrlicht IMesh (Referred to as "mesh" here) into a Bullet Multiple Convex Hull shape (cShape). Works with any vertex type too.

Nice.

Would be nice to know how to bind the TerrainSceneNode, tho. I can't seem to get it working using a 512x512 bitmap.

Well, I guess that won't work since blindside creates a convex hull and a terrain definitely has a concave shape. I currently also have this problem with my Userdefined Newton bodies.

That's what come out if you try to make a convexhull of a hut in Newton. (Collision is represented by lines)

BSP is another thing as well. I created a tunnel demo game and the balls just passed through the walls and floors.
