Constructors

Methods

  • getData(options: any): any
  • setPosition(options: any): void
  • Bind the HUD to a new PlaceableObject and display it

    Parameters

    • object: PlaceableObject

      A PlaceableObject instance to which the HUD should be bound

    Returns void

  • clear(): void
  • Clear the HUD by fading out it's active HTML and recording the new display state

    Returns void

  • _render(...args: any[]): Promise<void>
  • activateListeners(html: any): void
  • render(force?: boolean, options?: { left: number; top: number; width: number; height: number; scale: number; focus: boolean; renderContext: string; renderData: any }): Application
  • Render the Application by evaluating it's HTML template against the object of data provided by the getData method If the Application is rendered as a pop-out window, wrap the contained HTML in an outer frame with window controls

    Parameters

    • force: boolean = false

      Add the rendered application to the DOM if it is not already present. If false, the Application will only be re-rendered if it is already present.
