i know i already asked for this but i spend a lot of time trying to fix my line but i just cant, without GLStateManager.translate and rotate the line doesnt draw :( (i tried to render the line in PlayerRenderEvent.Pre JUST IN CASE IT WOULD WORK but is the same)

sorry for posting in the wrong forum but i dont know where to post my posts
