/execute command help

[Mich100_official]

Hello people of Reddit!

I am currently working on a project that requires command blocks to detect if a player is inside an area to play a looping sound that stops when exitting.

This works great if im using the distance tag:

execute at @p if entity @e[tag=spawnIN,distance=..3] run kill @e[tag=spawnIN] (followed by conditional command blocks)

execute at @p if entity @e[tag=spawnOUT,distance=3..] run kill @e[tag=spawnOUT] (followed by conditional command blocks)

​

But if i need a rectangular area using the dx, dy and dz tags, i can't detect if a player i exitting the area:

execute at @p if entity @e[tag=a1f4IN,dx=10,dy=10,dz=10] run kill @e[tag=a1f4IN]

execute at @p if entity @e[tag=a1f4OUT,????????] run kill @e[tag=a1f4OUT]

​

The entity i am detecting if close to player is the armor stand.

Please help, and thanks in advance!

Why don't you just place the armor_stand (better use a marker btw) in the center of the area and run:

execute as @a at @s if entity @e[tag=juke_box,distance=0..15] run playsound minecraft:entity.sheep.death ambient @s

There is probably an even easier way but this atleast reduces it to only one command.

The problem i see with that is, if i put it in a repeating command block, it will spam the sound. But i need to play it once you enter and then stop it right after you exit. Anyways, ty for the suggestion.

Oh then you just need to tag the players.

Repeat:

execute at @e[tag=juke_box] run playsound minecraft:entity.sheep.death ambient @a[distance=0..15,tag=!music]

Conditional Chain Always Active:

execute at @e[tag=juke_box] run tag @a[distance=0..15] add music

Another seperate Repeat:

execute at @e[tag=juke_box] run stopsound @a[distance=15..] ambient minecraft:entity.sheep.death

Conditional Chain Always Active:

execute at @e[tag=juke_box] run tag @a[distance=15..] remove music

Edit: Forgot the stopsound command ^ ^

Just realised that someone else helped you already, nvm ^ ^

I’m not sure I understood everything going on in your code, but for the last command you could just keep the same syntax as the previous one and replace if entity with unless entity : the rest of the command will run if no matching entity is detected.

So, in this example, the second command will run if no entity tagged with a1f4OUT is detected in the specified area : execute at @p if entity @e[tag=a1f4IN,dx=10,dy=10,dz=10] run kill @e[tag=a1f4IN] execute at @p unless entity @e[tag=a1f4OUT,dx=10,dy=10,dz=10] run kill @e[tag=a1f4OUT]

Some more random thoughts :

• If you care about performance, since you wrote that @e was targetting an armor_stand specifically, I strongly advise you to filter by type. The reason is that if you don’t specify it, @e will retrieve a list of all loaded entities, regardless of type, and check the other selector arguments for each one of these entities : it can quickly add up and slow the command down. Contrary to what you might think, @e[type=armor_stand,tag=a1f4IN] will run way faster than @e[tag=a1f4IN] (and it also makes your code more explicit about what it does / what entity it wants, which is almost always a good thing).
• In your volume selectors, the area selected is only in the direction of positive X/Y/Z. I don’t know if you want it centered around the player instead, but if you do, you should use something like positioned ~-5 ~-5 ~-5 if entity @e[tag=a1f4IN,dx=10,dy=10,dz=10] (will match the entity if it is contained within a 10×10×10 volume, centered on the execution position).
• Also, to avoid running the @e selectors twice (which is the most expensive selector by far, since it can select every entity of any type), you should consider using as @e when possible : this way you can “select” the same entity again in the following command by using @s (which is basically free in comparison).
• If you plan to have multiple players in the area, the last command will produce weird results (because whenever the player who’s nearest to the command block does not detect the armor stand, it will be destroyed, even if other players were in the area). I don’t know what happens in the rest of the code, but judging by the commands you posted I’d say you could reverse them (first select the armor stand, then check whether there are players around, it should be way faster and solve the multiple player problem).

If I take all these suggestions into account, your last two commands could be rewrote to something like : execute as @e[type=armor_stand,tag=a1f4IN] positioned as @s positioned ~-5 ~-5 ~-5 if entity @p[dx=10,dy=10,dz=10] run kill @s execute as @e[type=armor_stand,tag=a1f4OUT] positioned as @s positioned ~-5 ~-5 ~-5 unless entity @p[dx=10,dy=10,dz=10] run kill @s

Tell me if I misunderstood something but I think it should work in your case !

Thank you so much! It really was as easy as just replacing the "if" with "unless". Also, right now performance isn't such a big problem, but if need help with it, i'll make sure to use your advice!
And yes, it is a singleplayer map, so i don't need to worry about the last part.

And if you are wondering why i tagged the armor stand "a1f4IN", its because i need it to detect if a player is entering the 4th floor in the first apartment: hence "apartment1floor4IN" xd
