Ok. Now I need help. For some reason after one instace of a spell is destroyed, it bugs up and the rest don't work.

Sorry if the code is hard to understand or is terrible to read:

JASS:
library LightningHammer initializer onInit requires SpellEvent, KT, xefx, GroupUtils, OneLocation, LightningChain

    globals
        private constant integer ABILITY_ID = 'A003'
        
        private constant real SPEED = 30.
        private constant real TIMER_PERIOD = 0.03125
        
        private constant string LIGHTNING_TYPE = "CLPB"
        
        private constant integer LIGHTNING_COUNT = 1
    endglobals

    that was pretty good!

    really cool! I saw the game before but always thought it's just a half as good double dragon. Now I realize it actually has a lot of depth!
  • The Helper The Helper:
    I just saw a bunch of running and jumping past all the enemies look like it was scripted as he said I guess I should have watched the whole thing. I only got a couple of minutes in. You should post that video in the forum Tom

    Currently busy with making the run even better, so I'll post that new one once I'm done. Right now, I had to modify the emulator itself, the tools that makes this video, and some RAM address disassembling / reverse-engineering to get the right values, and such.
