Lines

The line graphic object can be used to draw lines using Excalibur. The Actor GraphicsComponent centers graphics by default, so it might be desireable to set the anchor to (0, 0);

const lineActor = new ex.Actor({
  pos: ex.vec(100, 0),
})
lineActor.graphics.anchor = ex.Vector.Zero
lineActor.graphics.use(
  new ex.Line({
    start: ex.vec(0, 0),
    end: ex.vec(200, 200),
    color: ex.Color.Green,
    thickness: 10,
  })
)
game.add(lineActor)
