Thanks guys for the quick and helpful responses. I will have a look at them and see how I go, and if I have any other problems I'll post them in this thread.
Oh, and are there any tuturials you might recommend for making a menu bar that pops up, say, when you click on an ant nest? It would need to show:
-# of resources (food)
# of forming/stored ants for different types
-click to make warrior ant (-3 resource)
-click to make worker ant (-1 resource)
Or something like that. I'm sure if I looked I could find something, but do you guys have any recommendations that would get me what I need? Jeez I must sound so lazy...
