I've known myself for a long time and a lot about Minecraft and its servers.
But there's one thing I do not know, namely: when I enter a command e.g. / gm 1 or / vanish, then every guy on my server sees that I went into game mode or Vanish. I don't want that. Is there a gamerule or something like that that turns off these texts? That no one sees that I went into game fashion or something?
No you can see if there's a plugin for it
/ gamerule sendcommandfeedback false. Assume you mean that. So if the chat is like this, xy's game mode has been changed to creative then it works.
Yes exactly
k thanks
But. Look at Idiot196's answer
By the way / vanish can be abbreviated to / v
Thought that only applies to the blocks
Sendcommandfeedback
Good thing you know now.
