The purpose for the blast door block is to allow the passage between blocks without damaging them. Two of its sides have half a meter of space between it and its neighboring block. This in turn allows for the creation of doors mechanically controlled by rotors and/or pistons that can slide next to other blocks without any damage occurring.


Blast door blocks are similar to armor blocks, however have a narrow profile and smaller collision box so not to damage surrounding blocks. These can be used in conjunction with pistons for example to create a large functioning door.

The blast door has been made mostly obsolete by the Airtight Hangar Door.

  • All blast door blocks currently have no deformation enabled, meaning they will stay the same shape till they are completely destroyed
  • Since pistons are never airtight, it is impossible for a room with a blast door leading to space to be pressurized due to the gap between the blast door and neighboring blocks.
