Minecraft /execute if PREDICATE [1.19] Command Tutorial

Learn how to use predicates in this Minecraft predicate tutorial for 1.19/1.18/1.17/1.16. If you've ever wondered what /execute if predicate is, then this video is for you! Predicates are a more advanced datapack feature that let you detect very specific things. It could be the answer to How to detect light levels, y level, NBT tags, or even how to detect rain! Predicates are a super useful part of any datapack or command block project!

In this Minecraft predicate tutorial, you'll learn how to use predicates in Minecraft, and how predicates work in datapacks (data packs) and how to detect things in Minecraft 1.16! People always ask how to detect people falling into the void in bedwars, and this is one way to do it! Predicates are super useful to detect light levels, detect rain, detect when a player is sneaking, or detect items in hand. There are so many different uses, and when used in combination with other execute subcommands like /execute if score, and /execute in general, you can do some great things! Predicates are a relatively recent addition to Minecraft, and this tutorial is completely up to date in Minecraft 1.16 (and 1.17!)

[@GameMaker04]

Great videos, thank you. Wondering if its possible to use predicates to compare two entities. For example to see if a player is within a cube area around a named armorstand. Not using spherical range but rather see if the player is within a cube volume. I see the location with min and max values but not sure if they can be applied in game in this way.

[@Legitimoose]

Hmm, it's certainly an interesting idea! I don't _think_ you could, but I also couldn't completely rule it out without trying. If you find out that it's possible in some way, let me know!

[@GameMaker04]

@@Legitimoose well here you go.. predicate is as follows. you can change the distance range to whatever. Below the predicate definition is an example call to it. { "condition": "minecraft:entity_properties", "entity": "this", "predicate": { "distance": { "x": { "min": 0, "max": 10 }, "y": { "min": 0, "max": 10 }, "z": { "min": 0, "max": 10 } } } } in my world I use an armorstand at spawn to hold many variables as scores and tags. so this example calls the distance check from me the player to that armorstand called "variables" execute as @p at @e[name=variables] if predicate sbox:cubedistance run say nearby

[@Legitimoose]

@@GameMaker04 YOOOO WHAT I honestly didn't know quite how distance would work but that makes so much sense now that I see it! That is actually awesome, thank you. EDIT: pinned because i think people might find this useful, and I totally glossed over it in the video!

For those that would like to know. When it comes to the performance of NBT selectors vs predicates in @a selectors. Predicates are up to 10x faster than going nbt={...}, so if you need to check NBT of a player predicates are the best option for selectors

[@Incommensurableme]

Because I was bored, i did the math at 5:30. from what was on the screen, he showed 7 samples. {9,8,8,6,7,10,10} add the array and you get 58. then you get the average: 58/7 = 8.2857 divide the average from the total number of players: 8.2857/16 = ~0.51 so to anyone who asked the question of "Is it really a 50/50 chance?" Yes, yes is.

Hello LegitMoose, i have a question. Can i do commands or trigers with mentions, example: "trigger ban (set) Gamer1337", i just don't want to use cheats on our server with friends and only some of commands will be working. Also i've come up with idea that every played gets theyr own tags, and when you type trigger ban, list of player comes up in a chat by tags, when you click on player, well, it bans them. Sorry for bad english, i'm russian

[@Legitimoose]

Hi! You can't use mentions like you said (the general term is "arguments") and you also can't run ban, or op commands from a command block or datapack sadly. I do think this is possible though! You'd just have to come up with another way to choose players (@p, or setting a scoreboard or something). I think your idea with the tags could be possible in some form too! If you have any more questions feel free to ask! (and your english is good!)

[@pinklasagnamemes]

@@Legitimoose i was kinda predicting that, i thought there would be some kind of "not straight" answer like we are doing custom commands with trigger, but thx for double aprouving. I really hope they add custom commands in datapacks in json, like custom crafting recepie. Thx for your tutorials, i was interested in datapacks and i started learning. When i wrote some "code" i saw that you can write predicate after execute, i didn't bother until this tutorial came out, they actually make everything easier.

If any of you are starting to go through the comments, wondering why in the world it isn't working for you on 1.21, don't worry I have your solution. Minecraft changed the folder naming conventions for data packs in 1.21 for some reason, so instead of naming your folders "functions" or "predicates", don't make it plural. The path should be .../predicate/detect_sneak.json.

All we need now is to have a simpler way to make custom crafting recipes using command blocks in the crafting table, then command blocks will be more popular than datapacks and mods

[@TerryProthero]

Useful video. Question. Did you do any videos on tags. Not the tag command. That's different. What I mean is that minecraft has tags for things like beds. #minecraft:beds is a json file that has a list of the different kinds of beds. I can then use the clear command to clear all beds from the inventory, for instance, by using that tag. They can also be used in crafting recipes. Like the crafting recipe for making a crafting table uses a tag to refer to any type of plank. That works fine for any tags already built into minecraft. But can I create my own tags for lets say concrete powder? I tried it, and the game ignores any tag I try to create. Is it impossible to add my own tags? Or am I just doing wrong? What folder do they need to be stored in, etc. And I noticed a replace true or false option in some of them. I have no clue what that means or why one might use it. I have already done some work with resource packs and datapacks. But I'm still a bit of newbie at both.

How do you make randomization like a dice? For example if you wanted a 33% chance to get nausea, a 33% chance to get levitation, and a 33% chance to get jump boost, how would you do it? I think the normal method would treat those independently, and would have a chance of none of them happening, or multiple of them happening at the same time.

If I want to test out a wither skeleton farm in a creative world before building it in survival and I need to spawn proof the fortress with pressure plates, can a predicate help me with that? I basically need to test nether bricks to see if they have an air block above them, and if so, replace the air with a pressure plate. Nothing I’ve tried has worked yet, and using /fill x y z x y z minecraft:stone_pressure_plate replace minecraft:air just leaves big stacks of pressure plates everywhere that shouldn’t be possible. I’m completely stumped but I really don’t want to manually place pressure plates in a 256x256 area to spawn proof it all.

I've done my best to put that in a regular function, but couldn't get it to work. There's a space for nbts in the predicate generator but when I copied the code into the .json file it didn't have correct syntax.
