So can you somehow make holograms show something different for each player? You can do animation, ok, but I want without animation. For example Someone presses the left button, then the word "Left" is displayed on the hologram only for the player who pressed the button, and when the other presses the right button, the word "Right" appears on the hologram Hologram displayed. Does anyone know how to do it if it works?
Do you work in single player or multiplayer (with plugins)?
Multiplayer on Aternos server with plugins. So in single player it would be easy.
OK. That would be possible. But probably only with a custom plugin. Do you have experience with programming?
Yes on python
Java a bit
And I don't think you can load your own plugins on Aternos servers.
With Python, you won't get far at Spigot. I would just look for a plugin on Google. Otherwise, maybe look for help on SpigotMC.org!
