Aggression Indicator

Aggression Indicator is a lightweight Fabric mod that displays clear, color-coded eye icons above mobs, helping you understand when a creature is close to detecting you, becoming alert, or actively targeting you.

Indicators are player-specific and server-aware, so each player only sees the aggression state that applies directly to them. A mob targeting another player will not incorrectly appear aggressive toward you.

Indicator States

Yellow Eye: You are close to the mob’s detection range, and it may notice or react to you soon.
Orange Eye: The mob is alert, angry, searching for you, or attempting to acquire you as a target.
Red Eye: The mob has actively selected you as its current target.
