I need a plugin to stop a player from flying and using the /speed command whenever they are in pvp combat. If this plugin already exists, sorry.
Do you already have a plugin that determines if the user is currently fighting or would that be part of the request?
Sadly, that plugin does not have an API which I could use and it is so complicated that rewriting it for this request would be an overkill. Although, somebody might still do it
Apex You can set in the config to have potion effects removed on pvp, and fly on pvp. (With combatlog)
