Detect individual Collisions

[jbv]

Use the intersect fonction inside a repeat loop.
I did something similar last year : the user was drawing
a selection rectangle on the screen, and various objects
were changing their bordercolor in real time if they were
(or weren't) inside the selection rect. I was even able to
implement multiple selection (using the shift key and
comparing the current selection with a list of previous
selected objects).
Speed wasn't a roblem on a Mac 9600 / 300...

(like the timeline in Adobe Premiere) I know this is possible, but how do I do it fast..... Checking every rectangle with repeat is to slow.....and the only idea I have now is to make a list in a hidden field-table for every new created rectangle......
