Minecraft – Executing a testfor command not working

minecraft-commandsminecraft-java-edition

I'm working on a capture the flag minicame in Minecraft 1.8.1. One of the features is automatically picking up flags when a valid player is in range. To accomplish this, I placed an armor stand inside each flag.

The goal is to get that armor stand to test for valid players (i.e. not on the same team, doesn't already have a flag, etc.) and set the block that was the banner to air. Each flag has a certain rotation value that is used to tell what team it represents – in this case, a rotation (ry and rym in the command) of 0 means the blue team. So, this command should tell all armor stands with a rotation of 0 to check for players not on the blue team who don't already have a banner.

Here's the command that isn't working:
execute @e[type=ArmorStand,ry=0,rym=0] ~ ~ ~ testfor @p[r=2,score_hasBanner=0,team=!blue]

And here's the error: Failed to execute '/testfor @p[r=2,score_hasBanner=0,team=!blue]' as Heads Up ("Heads Up" is the custom name of the armor stand, don't worry about why)

This error tells me that the execute command must be working fine, meaning it's a problem with the testfor command. However, using the testfor part on its own works perfectly.

Any ideas? Thanks in advance.

The command itself is completely fine, and works for me:

Make sure:

  • You are within range of the ArmorStand that is actually executing the command. If you have multiple ArmorStands with 0 rotation (likely, as they spawn like that by default) the output will only show the result of the ArmorStand that happens to execute last, which may not be in range.
  • You actually have a hasBanner score of 0. The default score for an objective is unassigned, not 0, so make sure it's being set to 0 somewhere.
  • You are not on blue team.
