Hi,
I am trying to move a sprite around the screen using the cursor
keys, my code is below (its very basic)
Is there a better way than using "self.sprite.stop()" to stop the
sprite moving?
I tried a few ways mentioned on this forum but I cannot get them to
work, such as:
self.sprite.remove_action( self.action )
I am very new to python programming so any advice appreciated
Thanks.
