Please give 1. the source code of class Tail and 2. the error message that the compiler gives you (or a clear description of what "does not work" mean). Also, the given source code of class Player misses the first line. Live long and prosper, Spock47

Well, there you have it: it says, that you have to give 4 arguments, but you only give three arguments. You give "r, g, b", but it needs "player, r, g, b". Note: Again, the presented source codes aren't complete (the start for class Player is missing, the start and end of class Tale is missing). Live long and prosper, Spock47

Ah. Try: 
getWorld().addObject(new Tail(player, r, g, b), getX(), getY())
