Checking How Hitboxes Change When Sneaking, Crawling or Riding

A player's hitbox changes size depending on their pose. With the pack's red outlines, you can watch these changes clearly. This helps you understand where you can fit and where an opponent can be hit.

Compare Standing and Sneaking

1. Enable hitboxes with F3 + B.

2. Press F5 to switch to third-person view so you can see your own red outline.

3. Stand still and note how tall the red box is and where the orange eye-level line sits.

4. Hold your sneak key. The red box shrinks to match the crouched model, and the orange line drops with your head.

Watch the Crawling Pose

1. Stand under a one-block gap, such as a trapdoor closed above you. You can also swim and surface into a low space.

2. When your character drops into the crawling pose, the red hitbox flattens around the low model.

3. This shows how small you become while crawling. Use it to test which gaps in your base a player could squeeze through.

Riding a Mount

1. Mount a horse, pig or other rideable mob.

2. In third person, you will see red outlines for both you and the mount. The crimson look vector still shows where you are facing while you ride.

3. Watch the red outlines to judge how much space the mount needs when you steer it through doorways and tunnels.
