height	number	The height of the health bar. Defaults to 12.
percent	number	The current health percentage (from 0.0 to 1.0).

Methods

constructor()

function constructor(barColor?: object): void

Initializes the model. Sets up the backgroundNode and barNode drawing them as rounded rectangles, attaching them, and defining a default pivot point of (width / 2, -64). Sets default health and max health to 100. An optional barColor can be provided to override the default green.

setSize()

function setSize(width: number, height: number): void

Reconfigures the width and height of the bar. Redraws the backgroundNode and barNode, updates the pivot point, and reapplies the current percentage.

setHealth()

function setHealth(health: number): void

Updates the current health value and recalculates the percentage by calling setPercent.

setMaxHealth()

function setMaxHealth(max: number): void

Updates the maximum health value and recalculates the percentage by calling setPercent.

setPercent()

function setPercent(percent: number): void

Updates the visual representation of the health bar. Uses setScaleX on the barNode for efficient resizing without needing to redraw the shape.

update()

function update(dt: number, user: any): void

Updates the model every frame. Updates health and max health from tick.health and tick.maxHealth. Counter-rotates the health bar to negate the parent entity's rotation, ensuring the bar always remains horizontal.
