Grabbing Blocks with the Mechanical Arm

The mech's mechanical arm is your primary tool for moving blocks. While piloting, look directly at any block you want to collect and press Left-Click. The arm will grab the block instantly. This works on almost any block in the game, including unbreakable bedrock.

Placing and Throwing

Once you're holding a block, you have two options:

Place it: Press Left-Click again to set the block down in front of you.
Throw it: Hold Right-Click, then release to hurl the block with force. Thrown blocks deal significant damage to mobs and can break through obstacles.

This grabbing and throwing system makes the mech invaluable for construction projects, mob defense, and environmental manipulation. You can rapidly collect materials or launch projectiles without leaving your seat.
