The Circle FX Controller.
This FX controller manages the circle effect for a Game Object.
This effect will draw a circle around the texture of the Game Object, effectively masking off any area outside of the circle without the need for an actual mask. You can control the thickness of the circle, the color of the circle and the color of the background, should the texture be transparent. You can also control the feathering applied to the circle, allowing for a harsh or soft edge.
Please note that adding this effect to a Game Object will not change the input area or physics body of the Game Object, should it have one.
A Circle effect is added to a Game Object via the FX component:
const sprite = this.add.sprite();
sprite.preFX.addCircle();
sprite.postFX.addCircle();
Constructor:
new Circle(gameObject, [thickness], [color], [backgroundColor], [scale], [feather])
