Large Constructor

Large Constructor is a Block that assembles large multi-tile structures directly in the world. It can create any eligible 3x3 or 4x4 block available in the game, giving it greater flexibility than smaller constructors that are limited to a predefined subset of buildable blocks. The constructed building is produced as a single block payload which the Large Constructor ejects into the world in the direction it faces.

The Large Constructor functions as a production/placement building and therefore integrates with the game's factory and power systems: it consumes the required item inputs to assemble the target structure and must be powered and supplied like other crafting Blocks. It is often used to automate the deployment of defensive structures, production blocks, or other installations that occupy multiple tiles and would be impractical to build by hand at scale.

When a construction cycle completes, the Large Constructor outputs the finished block payload along its facing direction. It will not begin a new construction run until the previously created payload has completely exited its output area, so placement routing and clear output space are essential for continuous operation. Because the block is emitted as a payload, the Large Constructor can be connected to conveyors, pneumatic pipes, or placed so that the payload lands directly in its intended location.

Large Constructor also supports logic interactions. It can be controlled or queried by the game's logic system (processors, memory cells, and other logic Blocks), allowing scripted building sequences, conditional construction, and integration into more complex automated bases. Logic can be used to select what the constructor builds, to coordinate multiple Large Constructors so payloads do not collide, and to manage resources fed into the unit.

Practical notes and usage tips:

• Plan the output direction and keep the output tile(s) clear; construction stalls while a payload is still occupying the exit path.
• Use conveyors or ducts to move the emitted payload into position quickly when you need to assemble structures at a distance.
• Coordinate multiple Large Constructors with logic to prevent payload jams and to build larger complexes in a staged manner.
• Ensure adequate item input and power supply; the Large Constructor behaves like other factory Blocks with respect to consumption and energy requirements.
• Because it can build both 3x3 and 4x4 Blocks, it is ideal for automating medium-to-large installations such as turrets, production arrays, and defensive walls that would otherwise require significant manual placement.
