Hi Everyone, During animation, I check for collision by creating a region for one of my moving objects and rects for others with FN RECTINRGN. Is it safe to repeatedly call the following to create a new region each time the object moves or should I be disposing of the region handle before creating a new one? humRgn = FN NEWRGN OPENRGN SETRECT(rgnRect,gHumRect.left,gHumRect.top,gHumRect.right,gHumRect.bottom) FRAMERECT(rgnRect) CLOSERGN(humRgn) Any advice appreciated. Cheers Bernie
