Possible new tutorial

[Albyfan]

Wouldn't be cool if you could add a tutorial for making an area that detects if you move or not and if you move then it'll do some given commands?

pls

[EricristianBros]

Well... there is already a FAQ for area (https://minecraftcommands.github.io/wiki/questions/areas)

Predicate

To detect the player moving you can use the following predicate

{
  "condition": "minecraft:entity_properties",
  "entity": "this",
  "predicate": {
    "movement": {
      "horizontal_speed": {
        "min": 0.01
      }
    }
  }
}

Commands

In older versions, where this predicate didn't exist, you can store the position values and compare to the previous tick

# In chat
scoreboard objectives add Pos.x dummy
scoreboard objectives add Pos.x.copy dummy
scoreboard objectives add Pos.z dummy
scoreboard objectives add Pos.z.copy dummy

# Command blocks
execute as @a run scoreboard players operation @s Pos.x.copy = @s Pos.x
execute as @a run scoreboard players operation @s Pos.z.copy = @s Pos.z
execute as @a store result score Pos.x run data get entity @s Pos[0] 100
execute as @a store result score Pos.z run data get entity @s Pos[2] 100
execute as @a unless score @s Pos.x = @s Pos.x.copy run say I'm moving
execute as @a unless score @s Pos.z = @s Pos.z.copy run say I'm moving

We have 4 scoreboards. Pos.x and Pos.z will be where the position will be stored and the .copy scoreboards contains the value of the previus tick

First we copy the values from the previus tick into the copy scoreboards (multiplied by 100 to retain decimal places), then, we update the current values from the data of the player Pos[0] and Pos[2]

Last, we compare if the values aren't the same, if they aren't. We know The player moved

Sincerly, I don't think its enough for an article but you can create the article if you want (questions/moving.md)

Edit: after several posts asking this, I will add it in a following PR
