How do I get the entity position after a dimension change?

the x y and z values in the new dimension should be the same, just make sure the actual procedure is being called in the new dimension and not the overworld

As seph said, you have the call the dimension first, then set it to air.

Hey Derex. You can do this through:

OnBlockRightClicked:

Switch dimension for provided (entity)player to [ID]

Set entity data logic NBT tag to "JustTeleportedToID"

OnPlayerUpdateTick:

If Get entity data logic NBT tag "JustTeleportedToID" = true AND Get dimension id of provided world [ID]

do Place air at x y z

do Place air at x y+1 z

do Set entity data logic NBT tag "JustTeleportedToID" to false.

You wont be teleported to the same coordinates however, but you can if you simply store the player coordinates in NBT tags and teleport the player there, then playing the second procedure.

OnBlockRightClicked:

Switch dimension for provided (entity)player to [ID]

Set entity data logic NBT tag "JustTeleportedToID" to true

Additionally, you might want to delete 4 blocks of air as you are spawned at the vertices of a block and not in the middle. Hope that helps.
