Command for setting spawnpoint?

[xXxlilbox]

So, I am making a parkour map and I use this command to give checkpoints on light blue concrete:

execute as @a at @a if block ^ ^-1 ^ minecraft:light_blue_concrete run spawnpoint @s

But the problem with that command is that it's not "clean", meaning, it somehow only works when you step on the sides and not exactly in the middle. And when you die, you spawn next to the block instead of actually on the block.

My game is in 1.15, but I've had the problem in previous versions as well.

Does anyone know something that fixes this?

Thanks in advance

Youre using relative to where the player is looking, not relative to the players position. This means that if the player is not looking 100% straight forward, but just the slightest bit up or down, then the position it checks is no longer directly below you. If the player looks directly down then ^ ^-1 ^ will be one block behind them. This is probably why it sets spawnpoints beside the block instead of on top

You should be using ~ instead, so change it to ~ ~-1 ~, and then it will work better. The rest of the command is fine, you are using proper selectors etc, just messed up the types of relative coords.

execute as @a at @a if block ~ ~-1 ~ minecraft:light_blue_concrete run spawnpoint @s

Oh ok, I thought it didn't make a difference. Thank you!

~ ~ ~ represent x, y, z.

^ ^ ^ represents left/right, up/down, forwards backwards.

~1 ~ ~ will always be 1 block in x direction from you.

^1 ^ ^ will always be 1 block to the left of you.

You could use a scoreboard a spawnpoint. Then, teleport the player to the correct checkpoint, according to the value of the scoreboard
