Reading the Red, Orange and Crimson Lines During Combat

With hitboxes on (F3 + B), every entity shows three color-coded lines. Each line tells you something different in a fight.

What Each Color Means

• Bright red box: This is the entity's hitbox, the space your attacks and arrows must hit. The color stands out against grass, stone and night skies, so it is easy to track.
• Orange line: This marks eye level, which is the height of the entity's head.
• Dark crimson line: This is the look vector. It points from the entity's eyes in the direction it is facing and shows its line of sight.

Using the Lines in a Fight

1. Aim inside the red box. Melee swings and projectiles only connect inside the outline. For a ranged shot, line up your crosshair with the box, not with the visible model.

2. Find the head with the orange line. Use it to find a mob's or player's exact eye height. This is useful when you peek over blocks or judge whether something can see over cover.

3. Watch the crimson line to read intent. If an opponent's look vector points at you, they are facing you. If it swings away, they have turned, and that is your chance to close in or retreat.

4. Use the colors in crowds. In a group of mobs, follow the crimson lines to see which ones are turned toward you.
