Methods

constructor()

function constructor(): void

Initializes the spell model, setting up properties like heartMaxOffset and heartSpawnTolerance. Fetches configuration from the game UI's spell schema to set the initial radius and creates the central pulsing circle DrawEntity.

update()

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

The main update loop for the spell model. If the user parameter is truthy, it triggers the visual animations by calling updatePulse() and updateHearts(). It then delegates to the parent class's update method.

updatePulse()

function updatePulse(): void

Animates the healing circle by incrementing the currentPulse property and adjusting the alpha (opacity) of the circle using a sine wave function, creating a throbbing visual effect.

updateHearts()

function updateHearts(): void

Manages the lifecycle of the heart particle sprites. It randomly spawns new hearts within the spell's radius and animates existing ones to float upwards while gradually fading out. Once a heart reaches heartMaxOffset, it is removed and destroyed.
