How can I make it so when a snowball hits snow the snow disappears? I am in 1.13.2 and trying to make a snowball spleef game.
/execute at @e[type=snowball,tag=ground] run fill ~ ~ ~ ~ ~ ~ snow replace air
I have tried that but it doesnt work. It may have something to do with 1.13.2.
/execute as @e[type=snowball] at @s if block ~ ~-1 ~ snow_block run setblock ~ ~-1 ~ air
in repeating command block will replace snow blocks under snowballs with air.
You're trying to use a tag called "ground". Tags are things you can add to entities or players. Entities don't spawn with specific tags. You need add a tag to something or spawn something with a tag using the Tags:[] nbt.
You could execute all of the snowballs and summon armor stands that destroy blocks after a few ticks (so the snowball doesn't fall through the blocks). Then kill the armor stands. My setup can be replicated by this command:
summon minecraft:falling_block ~ ~1 ~ {BlockState:{Name:"stone"}, Time:1, Passengers:[{id:"falling_block", Time:1, BlockState:{Name:"redstone_block"}, Passengers:[{id:"falling_block", Time:1, BlockState:{Name:"activator_rail"}, Passengers:[{id:"command_block_minecart", Command:"gamerule commandBlockOutput false"},{id:command_block_minecart,Command:"scoreboard objectives add time dummy"},{id:command_block_minecart,Command:"setblock ~ ~3 ~ repeating_command_block[facing=up]{auto:1, Command:\"execute at @e[type=minecraft:snowball] run summon minecraft:armor_stand ~ ~ ~ {Marker:1,Invisible:1,NoGravity:1, Tags:[tag1]}\"}"},{id:command_block_minecart,Command:"setblock ~ ~3 ~1 repeating_command_block[facing=up]{auto:1, Command:\"scoreboard players add @e[type=minecraft:armor_stand] time 1\"}"},{id:command_block_minecart,Command:"setblock ~1 ~3 ~1 repeating_command_block[facing=up]{auto:1, Command:\"kill @e[type=minecraft:armor_stand,tag=tag1, scores={time=3}]\"}"},{id:command_block_minecart,Command:"setblock ~1 ~3 ~ repeating_command_block[facing=up]{auto:1, Command:\"execute at @e[tag=tag1, scores={time=2}] run fill ~1 ~1 ~1 ~-1 ~-1 ~-1 air replace minecraft:snow_block\"}"},{id:command_block_minecart,Command:"setblock ~ ~ ~1 command_block{Command:\"fill ~ ~-3 ~-1 ~ ~ ~ air\"}"},{id:command_block_minecart,Command:"setblock ~ ~-1 ~1 redstone_block"},{id:command_block_minecart,Command:"kill @e[type=command_block_minecart,distance=..1]"}]}]}]}
What you want to try is if the snowball hits the ground, replace the snow with air and, lastly, kill the snowball entity.
An example: (run these commands in repeating command blocks, which are in your renderdistance, or in the spawnchunks, or run this in the looped function of a datapack):
execute as @e[type=minecraft:snowball,nbt={OnGround:1b}] at @s run setblock ~ ~ ~ air replace minecraft:snow_block execute as @e[type=minecraft:snowball,nbt={OnGround:1b}] at @s run kill @sThis places air at the position of every snowball which has a ground hit, and then kills itself.
