Instead of controlling the player mabe make a mod where you can open their inventory and take their stuff, but only on servers that approve it or LAN worlds, you could make it so if the mod isn't approved on a server it deactivates until you are off that server and In approved area's
You should make more for the mod like it could be like wall's with warfare you should add cars bombers and bombs, guns, tanks :), and nifes, and you could make so there are set servers where the players have ten minutes to get prepared then after ten minutes the players try to find the players they can kill them and stuff but the point of the game is to open their inventory and take something and then they are out. And you have to be either two or one block away to get their inventory. How is that for an idea? If you like my idea will you please approve this post or whatever that arrow button is. Please
but instead of just controlling the players you could add a bit more and plus how would control what point of view would you have and what could you do? I mean probably all servers would ban this so where could you use it?
