Minecraft – How to test what block is underneath you

minecraft-commandsminecraft-java-edition

I want to test if any player is on a certain block. I want to kill them if they are standing on that certain block.

execute's detect syntax is useful for this.

In 1.11 and below:

/execute @a ~ ~ ~ detect ~ ~-1 ~ sponge * /kill @a[c=1]

In 1.12 and above:

/execute @a ~ ~ ~ detect ~ ~-1 ~ sponge * /kill @s

This will kill anyone standing on sponge. The * is where you would put the block state, e.g for wool color=red or stone variant=granite.

Write this:

/execute @p ~ ~ ~ testforblock ~ -1 ~ minecraft:ice

then link it with a comparator to a block with a redstone torch on the opposite side, then connect that to the command block saying what you want it to do.

Minecraft – Testfor block with custom name

When you place a named block, it loses its name tag, making it impossible to detect if it was ever named. What you can do, however, is set a custom data value:

/setblock ~ ~ ~ diamond_block 1

Then, replace detect ~ ~-1 ~ diamond_block 0 with diamond_block 1. You can use values 1 through 15, but values above 15 are not supported.

Note: In some versions of the game (and possibly the latest updates), blocks with custom data may have a missing texture, and the custom data may not be saved properly. You'll have to look into this yourself as I can't test it at the moment.
