So I have a datapack which adds a certain ability. This ability is that when you crouch, it spawns a certain entity at your position. Everything works, except if you hold crouch, it spawns multiple. I can't make it only work if that entity doesn't exist already bc I want multiple players to be able to use this at the same time. So, I need a very specific way to identify between the different entities. I immediately thought that I could have the player's UUID as a tag, but I can't figure out how to do this, and I have no other ideas. If anybody has another idea, or a way to set a UUID as a tag, please help

I'm using lunar client for a couple of mods, and some of my mods are incompatible with mod menu, and I want to delete mod menu. But it just won't go away. I delete it? its back 3 seconds later. I delete it from the mod folder? Nope. If anybody knows how to delete this mod, please tell me

I was wondering, is it possible to add custom armor models with resource packs? Not retexturing, like actual 3d armor. It probably isn't but I want to know if its possible, and if so, how to do it

(26.1.2 but that isn't a tag) I have a custom datapack and I was trying to get rid of it but when I disabled it then removed it from the datapacks folder it stayed there. I could enable it and it worked fine, but it wasnt in the folder. I tried relogging and it was still there and perfectly functional. My datapack is immortal and I don't know why.

I have AIT downloaded and when I try and enter the TARDIS, it doesn't work. I thought maybe this had to do with other mods, so I tried just AIT, but it still didn't work. Idk what I'm doing wrong, and I would appreciate some help

I just started using create mod and want to know if there is a way to use redstone to increase rotation speed of cogs. I know about connecting different cogs to spin faster, but for example, can I make it so if I have a throttle lever set to 5, a cog spins slowly, but if I put it up to 15, it spins really fast?

I have a Nintendo switch but when I try to set it up on my tv it doesn't work. I know how to set it up as I have done it many times before, but for some reason it doesn't work. I think the issue is the power cable because I got the switch in australia and moved to the UK and when I moved I got a new power cable with UK plugs. The UK one recently broke so I tried the australian one and It doesn't work. I have it plugged into both the wall and the dock, and there are no damaged parts or anything, but it doesn't even have an error message, it just doesn't connect. What should I do?

(Actually 26.1.2 but that isnt an option yet) I'm making a dialog for my custom datapack and I want to know if it's possible to add a background to dialogs. Like, instead of just what you see but blurred, I want a full custom background, like the npc dialogs in bedrock.
