Tiling/masking problem

Hello everyone,

I’m making this interactive map. It’s made from tiles of dots, each turned on or off at run time depending on where the user has scrolled to. The tiles are 9x9 dots and I make the map from an array which is 20x40 in size. The swf then shows what is visible as you scroll over that map with a window which is smaller than a 3x2 tile space.

Hopefully that makes sense. The problem I have is that the dots which fall outside of the proposed viewing window still exist so when your mouse hovers over them, even though they’re hidden, they still interact. It’s a real pain in the ‘neck’. And by neck I mean Arse.

Here’s a picture:

Is there some way to mask the interaction of those dots? Each one’s a movie clip. I can hide them visually but that’s no good, people can still click on them then without even knowing they’re there…

I’ve tried loading the exported SWF into a movieClipLoader but that just automatically spills over like this again. It’s driving me crazy.

If anyone can help at all I’d be much obliged. Sorry for the long post if this is a simple question.

All the best
Mark
