[FONT=Arial]Hey guys, I am new to writing about my as3 trouble shoots. There is a TypeError with bringing my code from the timeline to a new Main.as. When debugging it says that my ‘slide’ in slideIn and slideOut function towards the bottom of the code = null?[/FONT] This worked on the timeline. Is there anything I am missing when i convert to classes?
TypeError: Error #1009: Cannot access a property or method of a null object reference.
