Mechanics: Manipulation and Ghost Blocks

Once a schematic is loaded, it can be manipulated using the Control GUI.

  • Movement: Schematics can be moved along the X, Y, and Z axes using the GUI buttons or by typing specific coordinates.
  • Rotation: The structure can be rotated in 90-degree increments.
  • Flipping: The structure can be mirrored across axes, which is useful for symmetrical builds.

Ghost Block Indicators

Schematica provides visual feedback to ensure accuracy during manual building. Ghost blocks change color based on the state of the block placed in the world:

Color Meaning
Translucent/Normal The block is missing and needs to be placed.
Red The block placed in this position is incorrect (wrong type).
Blue The block is correct but has the wrong orientation (e.g., a stair facing the wrong way).
Pink/Purple An extra block exists in the world that is not part of the schematic.
