I typed in the code for the key press and printed it and recieved an error. this is a screen shot of this:
http://www.nabble.com/file/p16735583/Squeak%2Berror%2B4.jpg A second question. How do I make a method to continuously check for this key press. If I have a morph class how do I create a method within it that says "while this morph exists check for this key being pressed and do something if it is pressed"? kennellgr wrote: > > Hi, > > I appreciate the help.
