Can someone help me in opening gates in 0.3e ? I could do it when it was 0.3d, but now everyone talks about cx,cy,cz or something like that. I didn't understand even a bit how to use it. Can someone explain me it ? I opened a topic once before too, but i didn't get proper answer. Please help me, i am coding right now and it is absolutely a big block.
