Talk:DemonicRage

DemonicRagev3.0

Lately I have completely rebuilt and improved Demonics foundation (still based on Module) I implemented Rednaxela's tree into a bare bones version of D's gun, which I plan to later expand after the new movement is fleshed out. The gun's new PIF I made should be quite quick. I'm not sure how it compares to displacement vectors or if it's type has been done before, but I will post it and D's Radar source code next chance I have.

I left it as is, with code commented out in case someOne wants to play with it..
