annotate demos/shooter/scripts/common/helpers.py @ 476:78a1eb57c074

Changed the way instances get deleted from the scene. Instances now get removed at the end of the frame as opposed to after their explosion action is complete. The old way was causing the odd segfault because the instance was being removed before FIFE was finished with it.
