Dunno if this has been suggested already, since I've mostly been ignoring this thread, but instead of using invisible members, you could do the polygonal hotspots entirely in Lingo without using any sprites. Unfortunately, code like that isn't for beginners, but if you can keep all the polygons convex then it's still /relatively/ simple. Much of the code required has been posted before IIRC, so it shouldn't be too hard to find an example. I wrote some code for intersection with any polygon (convex or concave, any number of points) a while ago. Unfortunately, although that code was just good enough to scrape by at the time, it's very messy/buggy (it was seriously rushed) and I wouldn't be happy about releasing it. I'm sure someone else out there already has some better code, even if it only does triangles, it shouldn't be a big deal to manually break the image-map down into convenient sections. - Robert [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).
