Block Swap in action.

Block Swap is a building mechanic that allows the player to replace placed blocks in a single step, rather than having to remove existing blocks manually first. Block Swap can be activated or de-activated via a toggle switch located at the top-left corner of the inventory.

The UI toggles for Block Swap (left off, right on).

Swapping blocks still requires that a player possess a tool with sufficient pickaxe power to free the target blocks, as the game performs a check for a tool of sufficient power before allowing Block Swaps to occur. Additionally, certain blocks can never be swapped via Block Swap (see list below).

When Block Swap is enabled, the player can place blocks over existing placed blocks, causing new blocks to "swap" with those already placed. When swapping blocks, existing placed blocks are automatically freed and dropped for collection.

Unswappable blocks

Some blocks cannot be swapped:

Tips

  • Block Swap can be used to extract ore veins that are hanging over a cliff and would cause the player to fall when broken.
  • Chlorophyte Ore can be swapped for mud to collect the Chlorophyte while allowing it to grow back.
    • This does not grant the Achievement "Photosynthesis".
  • Blocks beneath a Demon Altar/Crimson Altar can be swapped without destroying the Altar.

History

  • Desktop 1.4.1: Gravity-affected blocks can now be swapped out from the topmost tile downwards. At high enough tiers of pickaxe, they can be swapped out from any position like other blocks.
  • Desktop 1.4.0.4: Fixed a bug where blockswapped tiles maintain their cracked texture.
