hi, I'm looking for someone who's good with command to help me with make a basic Tardis in vanilla, I just need help with cloning and fill blocks with air.

I think I may be able to help.

 my gamertag or mc name is iballisticJambo

Hey Jambo,

I can't join you on Minecraft, but I have experience in TARDIS commands so I thought I might also be able to help :)

For the exterior, you can use /tp @s [co-ords] to reach the interior. The co-ords should be wherever you want to teleport to.

For the actual moving of the exterior: /fill [co-ords] air. The co-ords of this should be the bottom left and top right co-ords of the exterior.

For the cloning: /clone [bottom right co-ords of thing you want to clone] [top left co-ords of thing you want to clone] [bottom right co-ords of where you want the new structure]

Hope this helps :)
