Checking if player is an operator [1.19.2][SOLVED]

[RInventor7]

Hi! I have a block entity and when you right click it opens a screen. I want to open the screen always when on singleplayer and only for operators when on multiplayer. How can I check if the player is in singleplayer or multiplayer world? And how can I check if the player is an operator when on multiplayer? Thanks in advance.

Assuming you already have the ServerPlayer, you can do this:

// Can be static but doesn't have to be, depending on the use context.
public static boolean checkPlayerIsOp(ServerPlayer player) {
  return player.hasPermissions(2);
}

As for checking if it is singleplayer, there is probably a better option than what I was about to recommend.

player.hasPermissions(2) will check if the pleyer has cheats enabled which is the equivalent of ops in single player.

That will also handle the case when "open to lan" is used. Meaning guests won't have access.
