I am making my server, it is Hunger Games themed. The whole idea of the server is for every plugin to be made by me and my friend. Me and my friend coded the current plugins ourselves. We were trying to make our own small "NoCheat" like plugin to stop Speed Hacking and Fly Hacking. Currently we are having a very difficult time. We came up with a few methods but none of them worked 100%. If anyone has any ideas on how to properly stop flying and stop speed hacking please reply. Also, some other things that may help us: The exact value at which a player jumps without modifications / jump potion. The exact value at which a player sprints and walks with modifications / speed potions. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
