Glimmr Canvas-Based Drawing: Minor bug with UNDO button display in buttons examples #24

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When the first button pressed by the player is UNDO, the "current graphlink" 
value will hold a valid g-element (rather than null) after undoing; if the 
current graphlink doesn't store a button, the timer will go off after the 
action is undone and try to check the "tint" property of nothing (since the 
game state will have reverted to before the player pressed the button), 
resulting in a run-time error.

This only occurs if the optional UNDO display protection is not used (see the 
last paste block in the Simple Buttons example.)

The issue has been fixed on the SVN, but I have decided to delay a new formal 
release of the extension until more substantial changes are required.
