Remove child

[Nexios]

So i am trying to orbit a small sphere around a bigger sphere like so:

 

 

var orbit = new Sprite(loader.resources.RedB.texture);
stage.addChild(orbit);
orbit.anchor.set(0.1, 0.1);
orbit.position.x= Gball.x*1.3;
orbit.position.y = Gball.y/3;
orbit.scale.set(0.15, 0.15);

Gball.addChild(orbit);
animate();
function animate() {
    requestAnimationFrame(animate);

    // just for fun, let's rotate mr Honeypot a little
    Gball.rotation -= 0.05;

    // render the container
    renderer.render(stage);
}

 

 

 

now the only problem is that when i click on the button to remove the child, but want him to keep the position he had in the animation:

 

 

var ballX = orbit.x;
var ballY = orbit.y;
document.getElementById("bot").addEventListener("click", function () {
    var orbit = new Sprite(loader.resources.RedB.texture);
    stage.addChild(orbit);
    orbit.anchor.set(0.1, 0.1);
    orbit.position.x= ballX;
    orbit.position.y = ballY;
    orbit.scale.set(0.15, 0.15);
    Gball.removeChild(orbit);
    return false;
});

 

does anyone know how i might be able to do that?

stage.addChild(orbit);
Gball.addChild(orbit);

Whos whos child is?

I think you have to look at "Gball.toLocal(stage)" for global coords. Or something like that.

ok i have done something else now:

 

var orbit = new Sprite(loader.resources.RedB.texture);
stage.addChild(orbit);
orbit.anchor.set(0.5,0.5);
var orbitLocation = orbit.origin;
orbit.pivot.set(Gball.width*25,Gball.height*25);
orbit.position.set(widthHalf, heightBotb);
console.log(heightBotOrbit);
console.log(heightBotb);
orbit.scale.set(0.02, 0.02);

animate();
function animate() {
    requestAnimationFrame(animate);

    // just for fun, let's rotate mr Honeypot a little
    orbit.rotation -= 0.01;
    console.log(orbitLocation);
    // render the container
    renderer.render(stage);
}

 

and now i am trying to figure out how to get the sprites position while it is rotating around the pivot.

http://pixijs.download/dev/docs/PIXI.DisplayObject.html , look for toLocal and toGlobal. First param is just a point like "new PIXI.Point(0,0)" , second is object that you need coordinates related to (stage)

Thank you so much  will keep you updated if i make it
