Graphics Component

There is a new component, ex.GraphicsComponent to work with these graphics with ex.Actor's and other ex.Entity's

The ex.GraphicsComponent allows users to manage graphics with Actors and Entities in an easy way

How to use the Graphics Component

  1. Graphics using images (and any Resource) must be loaded before use
  2. Graphics like Sprites are like a window into an image
  3. Graphics like Canvas produce internal bitmap's which are large in memory and should be used sparingly or cached
  4. Graphics can be added to the GraphicsComponent on an Actor or Entity
  5. Direct access to the ExcaliburGraphicsContext

For most games, you will be using the graphics component off of Actors or plain Entities.

const image = new ex.ImageSource('./path/to/my/image.png')
await game.start()

const actor = new Actor({
  x: 100,
  y: 100,

Adding/Showing graphics

The graphics component allows developers to save named graphics to avoid passing around graphic object references if desired. These can be used to show specific graphics.'jump', jumpAnimation)'jump') // display the graphic
// equivalent to // display the graphic // hide the graphic

If no name is specified when added to the graphics component it is considered the 'default' graphic and is shown automatically.

// graphic considered 'default' and displayed automatically

Component Specific Overrides

  • visible: boolean

    • Shows or hides the all the graphics for this component
  • opacity: number

    • Applies an opacity to all the graphics shown for this component
  • offset: Vector

    • Offset in pixels to shift the graphics for this component
  • anchor: Vector

    • Anchor to apply to all drawings in this component if set, if null the drawing's anchor is respected by default (.5, .5) which centers the drawing.

Accessing the Graphics context

The graphics component allows access to the underlying graphics context.

const actor = new ex.Actor({...}); = (ctx: ex.ExcaliburGraphicsContext) => {;
  ctx.z = 99;
  ctx.drawLine(ex.vec(0, 0), ex.vec(200, 200), ex.Color.Green, 10);


The layer's component adds a way for multiple graphics to be on top or behind each other for a certain actor or entity.

Layers can be ordered numerically, larger negative layers behind, and positive layers in front.{ name: 'background', order: -1 }){ name: 'foreground', order: 1 })'background').show(myBackground)'foreground').show(myForeground)

// no longer display the background'background').hide()

There is always a layer named 'default' at order: 0
// is equivalent to'default').show(myAnimation)
