"grabbing a tool"

[Barry Levine]

Rob,

Thanks for the pointer. Yes, the "grab" command works well:

on mouseDown
	grab me
end mouseDown

I included a bunch of code from a stack (drag sample) I DL'd from 
somewhere (a reference given to me from someone on this list; forgive 
me, I have a terrible memory for names but wish to say "thank you!"). 
The code checks for the position of the object ("me") and prevents it 
from moving outside of the bounds of the stack.

Now I'm wondering how to determine when the object ("me") I am dragging 
touches another object. In other words, if I drag "me" over an image 
object that is moving around the stack window on its own accord (I have 
set it into motion), how do I know if I have successfully "touched" it? 
It can't be the "mouseLoc" because "me" would have touched it if any of 
the "rect of me" has passed over any of the rect of image "myImage".

The seeds of the answer are probably contained within my question. 
Think of this as "Pong" but all I am worried about is knowing exactly 
when the object I am dragging has passed over ("touched") another 
object (and there may be up to 27 of these "other" objects).

Thanks to everyone on this list (and most especially to Rob and Michael 
Lew and www.tactilemedia.com).

Regards,
Barry
