Greetings fellow humans, my interest in a plugin which automatically gives people gamemode is really high.
And seen the fact I don’t know Java or whatever language is used for plugins, it would be much appreciated if someone made this.
If you set force-gamemode to true in server.properties, that should do it.
Sorry for not specifying, but I want a plugin / solution just for certain players. Thanks for the response though

Any players with the permission minecraft.force-gamemode.override won’t be affected by force-gamemode.
