I am making a map and I need to kill any player that steps on an iron block, but the commands aren't working. Here are the commands:

  • Prequisites:

    /scoreboard objectives add IRONDEATH dummy
/scoreboard objectives setdisplay sidebar IRONDEATH

  • Repeat always active command blocks:

    /scoreboard players set @a IRONDEATH 0

  • Chain always active command blocks:

    /execute @a ~ ~ ~ detect ~ ~1 ~ iron_block 0 /scoreboard players set @a[c=1,r=1] IRONDEATH 1

/execute @a[score_IRONDEATH_min=1] ~ ~ ~ /kill @a[score_IRONDEATH_min=1]

The error is with your detect coordinates. ~ ~1 ~ means 1 block above the player's position, rather than 1 block below which would be ~ ~-1 ~.

If you don't need to do anything else with the IRONDEATH score, you could also simplify this down to:

execute @a ~ ~ ~ detect ~ ~-1 ~ iron_block 0 /kill @a[c=1]

You can use this command:

/execute @a ~ ~ ~ detect ~ ~-1 ~ iron_block 0 kill @p[c=1]

    @p only targets living players. After it kills the first player who actually stepped on the iron block, the command will activate again (as they're still on the iron block, just dead) and target the next closest player to kill, then the next closest player, and so on. You should use @a[c=1] to prevent this (though it doesn't really add anything to the earlier answer).
