How to program it

The AutoBuilder is a programmable building robot powered by AE2.
It reads a special Builder Pattern Item and places or removes blocks in the world based on its instructions.

How It Works

1. Create a Pattern

   • Use the Builder Pattern Item to select two corners in the world (r-click to select first corner, shift r-click to select another).
   • Right click air to copy the structure and save it to the item.
   • All blocks inside will be scanned and converted into a build pattern.

2. Edit the Pattern (Optional)

   • Shift Right-click the Builder Pattern Item to open a text editor GUI.
   • You can adjust delay, add commands like resets, removals, loops, or macros.
   • The number on the right is the delay added between commands in ticks (default 20 ticks or 1 sec). Set to 0 for maximum speed.

3. Insert Pattern

   • Place the pattern item into the AutoBuilder block.
   • Only one pattern can be inserted at a time.
   • You can use automation to insert/extract patterns out of the block.

4. Provide Power and Items

   • Connect the AutoBuilder to an ME network.
   • All building materials must be available in the ME storage system.
   • AutoBuilder withdraws the entire energy cost upfront before starting execution.
   • Supports crafting card.

5. Trigger Building

   • Use a redstone signal from the top to start the program.
   • The builder will execute instructions relative to its current facing direction.
   • A preview mode shows ghost blocks in real time, so you can check alignment before committing.
   • When finished, it emits a short redstone pulse on its sides.
   • Acceleration cards make it work much faster.

Key Features

• Relativity: Structures always align relative to the builder’s orientation
• Preview Mode: Real-time ghost block preview of where blocks will be placed or removed
• Upfront Energy Cost: Entire program energy is consumed at the beginning — if insufficient, the build won’t start
• Block Replacement with Recycling: Old blocks are returned into ME storage
• Full AE2 storage and power integration
• Redstone-controlled execution
