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 released DR3.0 early. I just got the melee movement working and the gun is untuned. 1vrs1 is temperarily random. I should of disabled some painting and tested for skipping turns, but it seems fine. -Jlm0924 17:11, 20 April 2010 (UTC)

Source Code

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

Comments

Very nice! Seems you've won the race to melee surfing? (EDIT: To melee surfing that collects stats I meant. Since apparently Shadow does do non-learning wave surfing in melee, and while I believe Portia learns a little about enemy targeting it's not technically a wave surfer) I'm a little surprised by DemonicRage still performing behind Glacier though. Perhaps do some 1v1 tests of the surfing to see how well it's working in a more basic situation? --Rednaxela 15:16, 23 April 2010 (UTC)
