  • Hello Amir,

    I do not know how I deliver the idea, but I will try.

    Let's say I have a white background for example, the background does not appear because it is behind the camera. What I want is when you move your finger over a place, the background will appear in the place of the swipe.

    This image may help to understand:

    what you need is to duplicate the effect in the touch moved area

    use the code below in a project and chose your effect PNG in a billboard

    // -----JS CODE-----
    // @input Component.SpriteVisual originalSprite

    // Where we want the new sprite to be
    var touchPos = data.getTouchPosition();
    var alignerPos = new vec2(
    (touchPos.x - 0.5) * 2.0,
    (touchPos.y - 0.5) * -2.0

    var newBindingPoint = alignerPos;

    // Get information about the original sprite
    var spriteObject = script.originalSprite.getSceneObject();
    var originalRenderLayer = spriteObject.getRenderLayer();
    var originalParent = spriteObject.getParent();

    // Create a duplicate of that object
    var newSpriteParent = global.scene.createSceneObject("newSpriteParent");
    var newSprite = newSpriteParent.getChild(0);

    // Set the duplicate to have the same properties as the original

    // Set the new aligner point
    var spriteAligner = newSprite.getFirstComponent("Component.SpriteAligner");
    spriteAligner.bindingPoint = newBindingPoint



    have fun :)
