Hi, ppl! I'm stuck with this question:
Modify the processActors method in ChamleonCritter, so that when the list of actors to process is empty, the color of ChamleonCritter will darken.

I only know three methods : setColor( Color c), getColor(Color c), Color(int r, int g, int b) but to make the critter darken, I will need the current values for r, g, b. But I dunno how.
