My brother has a problem with hooking people with fishing rods instead of focusing on survival. I know about the /clear command, but command blocks are only active when the chunk they're in is loaded, and I'm afraid that he'll go past that to get a fishing rod and start it up again. Since Minecraft is basically infinite, I can't keep placing command blocks whenever he moves away from one.

Is there a mod, command, etc. that can outright prohibit certain items from players' inventories no matter where they are in Minecraft?

    You do realize he'll probably just find another way to be troublesome right? Oh, and no more mending books for you.

    If he's not focusing on survival what's the problem? Just let him starve a few times. Commented Jan 11, 2021 at 12:12

    How is preventing him from doing that going to actually solve any problem?

    Strikes me that rpg stackexchange also frequently has questions roughly of this nature - where players don't have matching ideas of how best to have fun with the game. At that other site, the answer is almost always: rules based solutions won't address the underlying problem, which is that you're not "on the same page". Commented Jan 12, 2021 at 22:37

You don't need mods. Spawn chunks are always loaded, put your command block there.


Alternate Method: Use a datapack to run the /clear command. This works since datapack functions are always loaded, no matter where you are in the world. You can just reference a function in the minecraft function tag tick, and in the function add

clear <selector> <item> <count>

This will always clear x item(s), from y player(s), no matter where you are.

  • can't you paste this into a command block as well? And then just put that one into the spawn chunk (thx @HolyBlackCat) and have it run every tick with a redstone circle

    thats what the datapack trick is for. Datpacks can "hook" a function in to be run each tick. Thats explained in the article about Java functions: minecraft.gamepedia.com/Function_(Java_Edition). Putting them into the Tick tag runs them every tick

    @Hobbamok you could just do that, but from what I understand, the more commands you run every tick, the better it is to use functions instead of command blocks. Commented Jan 11, 2021 at 17:39

    I would accept this as an answer but i cant because for some reason my minecraft hates datapacks and its very hard for me to create them properly. its a good answer, though. thanks!

  • @PvParkour what happens when you use a datapack? Basic datapacks are also easy to learn. You can find many tutorials online about datapacks. Commented Jan 11, 2021 at 20:55
