/spawn

With this project can you use a command to get to spawn: /trigger spawn

The default coordinates are 0 64 0 . You cant take damage, move or fall for the next 3 seconds after you triggerd spawn. After you used you it, you have a 2min cooldown. This is to make it balanced.

If you set your Worldspawn / spawn to another coodinate or the hight is wrong (exp. you are in the air or in a block), you can change it. For that go to your world folder, go to datapacks and then to spawn_teleport data/spawn_teleport/function/cast_success.mcfunction

There you should see somewhere tp @s 0 64 0, just change to coords
