Display health bars above characters using CSS styling.
Use Drei's Html component to render styled health bars in 3D space. Update the health bar width by manipulating the DOM element's transform: scaleX() via a ref in useFrame. In projects on React Three Fiber 8, throttle manually with accumulated delta instead of passing an { fps } options object to useFrame.

const elapsedRef = useRef(0)

if (elapsedRef.current < 1 / 15) return
elapsedRef.current = 0
healthRef.current.style.transform = `scaleX(${healthPercent})`
})
