Minecraft execute detect command not working

minecraft-commandsminecraft-java-edition

So I am trying to create Mario in Minecraft and I had an idea for the pipes. I want to detect a block 4 blocks under the player and I have a block 3 blocks under the player so when you jump you go through the pipe. This command used to work perfectly until I closed out of minecraft and opened it again. I don't know whats wrong and if nobody knows then please provide an alternative. This is the command

/execute @a ~ ~ ~ detect ~ ~-4 ~ minecraft:wool 15 setblock 1179 64 -349 minecraft:redstone_block

I want it to detect black wool and then when it finds the black wool 4 blocks under the player it will create a redstone block powering a line of repeaters and command blocks that waits, teleports you down 1 block, waits again, teleports you down another, and waits a third time to teleport you down two to the secret room. The error that I am getting is

[21:28:27] Failed to execute 'detect' as Heroblind55246

Please help!

Edit: Now I get this error :

[19:26:15] Failed to execute 'setblock minecraft:redstone_block 1179 64 -349' as Heroblind55246

It will succesfully run the command, but when you check the commandblock you aren't standing above a wool block, so it says '[21:28:27] Failed to execute 'detect' as Heroblind55246'. Try to do something like this:

/execute @a ~ ~ ~ detect ~ ~-4 ~ minecraft:wool 15 say hi

I hope it will work!

Minecraft: Using /execute to detect if a Bottle O’ Enchanting has been thrown

Your command is working perfectly fine. Make sure it runs on a clock!

It has a couple flaws though:

not multiplayer friendly: You would teleport every player, once a bottle is in the air
suspended player: The player will not be able to move until the bottle hits the ground, as you're constantly teleporting him. This is especially bad if you happen to throw a bottle down a high cliff.

But here is an alternative solution, that is more reliable and multiplayer friendly!
The first thing you need to do, is to set up a scoreboard achievement: (type this in chat)

/scoreboard objectives add ExpThrown stat.useItem.minecraft.experience_bottle

This will count the number of times a player has thrown an experience bottle.
The next thing you want to do is to build a clock that activates a command block with the following command:

tp @a[score_ExpThrown_min=1] x y z

That is going to teleport all the players that have thrown an experience bottle to the specified coordinates (replace x, y and z).
Now, place a comparator facing away from that command block, into a new one with this command:

scoreboard players set @a[score_ExpThrown_min=1] ExpThrown 0

That will reset the objective, so that you only get teleported once.

Minecraft – Failed to execute fill command on player

For situations like this, I'd recommend running the command being executed itself (the /fill command) to see what the error is.

The main error appears to be that you're trying to fill a quarter of a million blocks, which is more the maximum (32678) that Minecraft allows for. You could reduce your fill region:

/fill ~-15 ~-15 ~-15 ~15 ~15 ~15 minecraft:diamond_block 0 replace minecraft:gold_block

Or, if the huge area is important, split it up into multiple commands:

/fill ~0 ~0 ~0 ~30 ~30 ~30 minecraft:diamond_block 0 replace minecraft:gold_block
/fill ~0 ~0 ~0 ~-30 ~30 ~30 minecraft:diamond_block 0 replace minecraft:gold_block
etc.

(I'd suggest not running either of these on a clock)

That should be it, but keep in mind that the command will also fail if there are no gold blocks to replace, or if you're too low-down/high-up so that the relative coordinate are selecting an area outside of the world.
