Ok so when you throw a snowball I have
/execute @e[type=Snowball] /setblock ~ ~-1 ~ minecraft:ice'
So this makes an ice path following under the snowball. I had some code something like this and it worked but I modified it and accidently broke it. So what is the correct code that I originally had that made this work? I also tried everything like
/execute @e[type=Snowball] /setblock minecraft:ice ~ ~-1 ~ and
/execute ~ ~-1 ~ @e[type=Snowball] /setblock minecraft:ice
last one I tried was
/execute @e[type=Snowball] ~ ~-1 ~ /setblock minecraft:ice
