Minecraft – How to detect a wool block with a color

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!

I assume, based on your previous question, that you want the number of affected armor stands stored on the player. For that there is no need for CommandStats or /tp. You simply need to ensure the commands are activated in the correct order for a /fill clock (see here for a tutorial that covers activation order via /fill).

Otherwise, the set of commands is essentially the same as those in your previous question, albeit adding instead of setting to mimic CommandStats.

Prerequisites:

Objective to state how many armor stands were near the player.

/scoreboard objectives add ASNum dummy

Clock commands:

The following must be run in numerical order on a clock.

1. Reset the player's ASNum score to a default of 0.

   /scoreboard players set @a ASNum 0
   

2. Cause armor stands around the player to increase their "ASNum" score by 1. This causes the player's score to be equal to the number of armor stands around them, rather than always 1, to mimic CommandStats.

   /execute @e[type=ArmorStand] ~ ~ ~ scoreboard players add @a[r=10] ASNum 1
   

3. Players with an ASNum score of 0 would be those not within 10 blocks of an armor stand. Players with a score of 1 or higher will have that many armor stands around them.

   /say @a[score_ASNum=0] had no armor stands near them.
   /say @a[score_ASNum_min=1] has at least 1 armor stand near them.
   /say @a[score_ASNum_min=10] has at least 10 armor stands near them.
