View Rainbow Hitboxes for Mobs and Blocks

Activating Debug Hitboxes

Press F3 + B while in-game to toggle the debug hitbox display. This shows the collision and selection boundaries for all entities and blocks in your view.

Rainbow Hitbox Effect

When debug hitboxes are enabled with this resource pack installed, the standard gray or white hitbox lines are replaced with bright rainbow outlines. This makes it much easier to:

• Identify mob positions in crowded areas
• See exact block boundaries when building or mining
• Track entity movement in dark environments
• Understand collision zones for redstone contraptions

Using Hitboxes Effectively

The rainbow coloring cycles smoothly across the hitbox lines, making them stand out against any background. This is especially useful when:

• Hunting mobs in caves or forests
• Aligning blocks for precise construction
• Debugging entity behavior in multiplayer
• Testing mob farms or traps

Press F3 + B again to disable the hitbox display and return to normal vision.
