question about collision volumes / trigger system

[Jacky_J]

What's the best way to go about creating a invisible collision volume for say a trigger system? Should i add a kinematic rigid body to the world (with response turned off), or just a basic collision object?

I tried adding a collision object to my world like this:

Code: Select all

	btCollisionObject *Object;
	Object = new btCollisionObject();
	btBoxShape *Box = new btBoxShape(btVector3(1, 1, 1));
	Object->setCollisionShape(Box);
	World->addCollisionObject(Object);

But it crashes inside btDiscreteDynamicsWorld::saveKinematicState after the update.
any ideas?

Thanks
