Meter Widgets
Meter widgets are commonly used for health bars, heart containers, ammo counters, stamina, charge levels, and other player or UI stats.

Meters can be setup quickly in the editor with a full preview and then updated at runtime using actions.
Widgets
A meter for discrete values (e.g., hearts, bullets, segments…).
A meter for continuous values (e.g., health, stamina, speed…).
A UI Image meter that uses transform scale, rect size, or animation frames.
A world-space meter for SpriteRenderer targets, using transform scale, sprite size, or animation frames.
A label that formats numeric values (e.g., 1/5, 50%, 100, or custom formats).
Tip
Meters can be nested inside other widgets, e.g, a Target Indicator that attaches UI to a target object.
