getBoundingBox() question

I am trying to use this code to know when the balls (there are 5 balls in my games) touch the bat, but i am getting the messages all the time! it doesnt work

what's up with that?

Code: Select all

	core::aabbox3d <f32> b=MyBat->node->getBoundingBox();
	
	for (int i=0; i<5; i++) {
			if (b.intersectsWithBox(Rooby[i]->node->getBoundingBox()))
				MessageBox(g_hWnd, "Collided!" ,"Good news", MB_OK);

	}

Seems to be correct IMHO. Maybe they are colliding all the time. Can't think of anything else now...

No, they are not colliding all the time, I see what's going on on the screen

From the API:

//! Returns the axis aligned, not transformed bounding box of this node.
//! This means that if this node is a animated 3d character, moving in a room,
//! the bounding box will always be around the origin. To get the box in
//! real world coordinates, just transform it with the matrix you receive with
//! getAbsoluteTransformation() or simply use getTransformedBoundingBox(),
//! which does the same.

So you must transform both the bat bounding box and the balls bounding box to see if they collide.
