possible to track the tap position on display screen ?

  • Hi El Be! There's actually a fairly simple way to do this that uses the Touch and Manipulate component. Basically, you add an object to the scene that's rotated 90 degrees in the X. And then a sprite child that's rotated back with Touch and Manipulate components added. Then, we have to add a small script to allow there to be a negative min distance. 

    Example project here. Look at the object MyMovableSprite. Test it out by dragging the Sprite in the Preview panel:

  • hey Travis, thank you for your quick response - meanwhile I found what I was looking for: it was the TapPosition Vector. 

    Which now brings me to the question how I could translate a normalized Position to Screenposition? Can you help me on that one? That would require to know the display size of the users phone I guess.... so how do I get those values?

    any help is truly appreciated 

    cheers Linus

  • Hi eL Be,

    Do you want to convert the touch position to world space? If so you can use the screenSpaceToWorldSpace() function found on the Camera component. You can check the details here:

    Here's a quick example of finding world space position from touch:

    //@input Component.Camera camera

    var touchPos = data.getTouchPosition();
    var depth = 1.0;
    var worldPos =, depth);
    print(worldPos.x + ", " + worldPos.y + ", " + worldPos.z);


    If you want to convert the touch position to the units used by SpriteAligner, you can translate like this:

    var alignerPos = new vec2(
    (touchPos.x - 0.5) * 2.0,
    (touchPos.y - 0.5) * -2.0

    And here's a full example script using that:

    //@input Component.SpriteAligner aligner

    var touchPos = data.getTouchPosition();
    var alignerPos = new vec2(
    (touchPos.x - 0.5) * 2.0,
    (touchPos.y - 0.5) * -2.0
    script.aligner.bindingPoint = alignerPos;


    Hope this answers your question!
