I'm trying to set up a basic collision detection patch - (move 2 objects around the screen - when they occupy the same space something happens.) I'm using the values I feed into [translate] to indicate the position of the objects. Is there any way other than using [translate] to know where objects are?

I think a simple way to do that should be by using the PMPD library. There are objects like tCircle2D, tSquare2D and many more that are useful to perform a "collision" test between two objects depending only on X,Y coordinates.

I can't remember whether or not the library is included by default in pd-extended.
If needed you can download it here:

See the patch attached below. Hope it helps.
