Hi! Thanks for your answer. But, as I said before, I'm new to using command blocks. I've read several forums, I didn't understand almost anything and I don't know how to deal with data packs. In the beginning, my idea was, whenever the player died or entered the server, the command block would give him the effect. But then, I decided that it is better for the player not to lose the effect since the panel gives the "infinite" effect. And about the milk, I will let it pass, it even creates a mechanic for the RP.So, I prefer to use only the panel, as I find the command blocks very complicated.I just want a simple command for the panel where, if the player dies, he doesn't lose the effect. Does it exist?
