SOLVED Button question

[PixelPush]

Looking for a way to keep a button functioning when it's invisible. Any pointers? (No pun intended

var btn = new BABYLON.GUI.Button("boat hotspot", "hello");
    btn.horizontalAlignment = BABYLON.GUI.Control.HORIZONTAL_ALIGNMENT_LEFT;
    btn.width = 0.07;
    btn.height = "100px";
    btn.color = "white";
    btn.background = "green";
    btn.left = 980;
    btn.top = -177;
    btn.notRenderable = false;
    btn.isVisible = false;
    btn.onPointerDownObservable.add(function(e) {
        console.log(e);
    });

Edit

 

Just figured this out, if any one else wants to do the same

- Set the alpha to zero. (Use a rectangle rather than a button to avoid the alpha being restored on mouse rollover

You are correct  alpha to 0 is the way to go
