How to Crawl Through One-Block Spaces

In standard Minecraft, entering a one-block-high gap requires swimming mechanics, pistons, or trapdoors. With Crawl on Demand, you can drop directly to the ground and crawl whenever you need to explore narrow tunnels.

Entering the Prone Position

1. Approach any opening that is one block high, or simply stand on open ground where you want to lie flat.

2. Press the default crawl hotkey: Left Alt.

3. Your character model will instantly drop into a crawling (prone) posture.

Navigating Tight Passages

• Use your standard movement controls (such as W, A, S, and D) to move forward, backward, or sideways while remaining flat on the ground.
• Steer your character into the one-block-high opening. Because your hitbox matches the prone stance, you will pass cleanly through gaps you normally cannot walk or sneak into.
• Once you exit the cramped tunnel and have enough vertical clearance to stand, press Left Alt again to toggle back to your standing position.

This makes cave exploration and mapping out tight underground routes far faster, removing the need to carry trapdoors or water buckets just to fit inside small crevices.
