rect1 X = rectangle 1 x location
rect1 Y = rectangle 1 y location
rect1 Width = rectangle 1 width
rect1 Height = rectangle 1 height
rect2 X = rectangle 2 x location
rect2 Y = rectangle 2 y location
rect2 Width = rectangle 2 width
rect2 Height = rectangle 2 height

This command will take two rectangular locations on the screen and see if they overlap. You will need to know the x, y, width, and height of both regions to test.

I'm still trying to find a real good logical use for this command with all the other collision commands available to you like ImagesOverlap, ImagesCollide, ImageRectOverlap, and ImageRectCollide. My guess is that this is the absolute fastest possible collision method available and useful to those wishing to write their own collision routines.

Unlike the other collision commands, there is no image to detect a collision with - simply one rectangular location overlapping another. You could probably use this command instead of the ImageRectOverlap command, as they are really basically doing the same thing (and I betcha this is faster).

This would be useful for very easy-going 'Monkey Island' games to check the position of your pointer against a screen location (or 'hot spot') when pixel perfect accuracy (heck, image graphics in general) are not really needed.
