Can Someone help me to make a good duel system? A system that all heroes will fight to each other the last man who stand will win. Can you help me with that?
1- You're gonna have to be a little more precise.
2- No one is going to make a system for you. They will help you, but not do all of the work for you.
Your best bet is to start working on it yourself (Don't aim too big, try to split the system into smaller little tasks), when you get stuck on a problem just post here regarding what you tried to achieve, what happened/ what went wrong e.t.c.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
