How do I make a command that triggers when I step on a block? [duplicate]

Question

I have been looking this up and watching videos on it for a week now. Nothing has helped! Please, does anyone know how I can do it?

Answer 1

There is a simple fix to this:

Have Repeating command block set to Always Active, with this command:

execute @a ~ ~ ~ detect ~ ~-1 ~ stone 0 tag @s add block

Next, have a command chain set to Conditional, Always active with command:

setblock x y z redstone_block

Next, have a command chain set to Conditional, Always active. Its delay in ticks is 2, with this command:

setblock x y z air

One block next to coordinates x y z, place a command block with command:

tp *@a[tag=block] x' y' z'

You can replace stone with the block of choice, and x' y' z' with the coordinates of the location where players are teleported to.

I hope this helps.
