So I want to make some battlefield type of game which I would call "Extreme Warfare", and I want to start off by making a so-called grenade that upon hitting a distance, it explodes.

I somehow want it instant, but I'm sure it's impossible, so the best option is using /summon to place a TNT on the landing spot.

I'll be using a Splash Potion of Poison as the grenade, since most grenades I know are green, and I want to throw it and produce a TNT once landing. So I thought of modifying this command:

execute @e[name=Potion] ~ ~ ~ summon tnt

The bits I need to deal with is the detection of landing, which then summons a TNT, and I also want to determine what potion it is referring to.

For this post, here's my question:

How to detect the projectile to land in order to summon a piece of TNT?

  • Does it need to work on every block? For example, only on grass or only on stone?

  • Can be in any block, but what I prefer is dirt or stone (most likely cobble). Commented Mar 6, 2021 at 12:59
  • If it only needs to work one a few blocks then that is quite simple to do and I'll post the answer but if it any that's quite a bit more work.

  • @Halesy Sure thing, as long as the command is suitable for Bedrock. Commented Mar 6, 2021 at 13:44

Thanks to penguin for suggesting another method.

Method 1

One command block

This should be an Unconditional, Always Active and Repeating. The command should be: /execute @e[type=splash_potion] ~ ~ ~ detect ~ ~-1 ~ grass 0 /summon tnt

Use multiple different command blocks for different blocks.

Method 2

For this to work you'll need two command blocks:

The first command block

This should be an Unconditional, Always Active and Repeating. The command should be: /execute @e[type=splash_potion] ~ ~ ~ testforblock ~ ~-1 ~ dirt.

The dirt here can be replaced for another block.

The second command block

This should be a Conditional, Always Active and Chain. The command should be: execute @e[type=splash_potion, c=1] ~ ~ ~ summon tnt.

Orientation

The arrows on the side of the command blocks should be facing in the same direction as each other. More specifically, the arrow on the first must point towards the second.

For multiple different blocks have multiple of the first command block all pointing into the second with different blocks in place of dirt.

  • Looks good. I'll try it later. Got some stuff to do. Commented Mar 6, 2021 at 13:58
  • You should be able to make this one command using the detect subcommand
