General

GMPermissions is a simple PocketMine plugin that adds permissions for fine control of gamemodes.

Commands

Use the command /nogm to prevent anyone from changing your gamemode

Permissions

Use the normal pocketmine.command.gamemode permission to give players the ability to change their own gamemode, and these extra permissions to define who can give/get which gamemodes:

gmchange.others - allows a player to change other players' gamemode

gmchange.spectator - allows a player to use /gamemode spectator

gmchange.creative - allows a player to be given Creative mode

gmchange.nogm allows a player to use the /nogm command

Give the gmchange.others permission to allow players to change anyone's gamemode

Give the gmchange.spectator permission to allow players to use spectator mode

Give the gmchange.creative permission to allow players to be be given creative mode (when 'restrictcmode' option is true)
