All Items Can Land v2 [MrBean, CLF78]
#1
Today i was looking at the code and realized it could be improved quite a bit. So here's my new version, which is 11 lines smaller than the original.

Quote:This code lets every item (except the Thundercloud) land on the floor when dropped. They will activate when a racer drives over them, and their effects will be identical to if the user actually fired the item themselves.
