feedback — hit feedback effects for the local player. Every effect is a pure function to a widget tree (or a camera offset), and the HUD's `feedback` field picks any mix of them by name: flash the character flashes red when hit (green when healed) shake the camera kicks and shakes, harder for bigger hits vignette a red vignette punches in from the screen edges on a hit heartbeat a throbbing dark-red pulse while health is low direction a bright arc around the screen centre points at the attacker feedback = "flash shake vignette heartbeat direction" -- or "all", or "none"

Low-health heartbeat. `low` is 0..1 how far below the threshold health is.

direction(W: number, H: number, angleDeg: number, a: number) → any

An arc on a ring around the screen centre pointing toward a hit. angleDeg: 0 = in front of the camera, 90 = to the right, 180 = behind.
