sorry for the late reply. I see, that's actually really handy (the parameter part. I think I have been avoiding funtions so I am going to spend a day and create a simple game where I can practice with functions and get a full understanding of how and where to use them in the event sheet)
Offset parmeter i see alot in the kiwi game, like if player is against wall, set offset to x-32, y, -122. I assume its just used as position for the player.
Thanks mate, have a fab new year :-)
