accessing variables of all children


Recommended Posts

Hi, i'm a beginner at pixi.js so please bear with me!

I'm trying to add a sprite of a certain type whenever the user presses a button.

However I need all the sprites to be moving towards the right every frame.

So for now I have the following code triggered when the user presses a button:

egg = new PIXI.Sprite(PIXI.loader.resources["images/newegg-02.png"].texture);

Which works fine, however I'm not sure how to access the X and Y values of all the eggs that currently exist in order to move them.

In the gameLoop function, just adding an egg.x += 4 doesn't work, so what do I do? Have also tried a for loop like so:

for (var i = 0; i < pubviewport.children.length; i++){
           pubviewport.getChildAt(i).x += 4;
