i am making a game in python 2.3.5 and i wanted to know if there is a command that would make it so one sprite will move to another no matter what the position is on the screen.
If you are programming games in Python it might be interesting to have a look at PyGame: http://www.pygame.org/
What you are looking for is the concept of 'Path finding'.
More technically, you might have a look into 'vector' usage (either 2D or 3D).
LocationCurrentSprite = Vector(...)
LocationNPCSprite = Vector(...)
distance = function of vectors
direction = function of vectors
