How to init a PIXI project if I don't load any resources into my PIXI project?

[caymanbruce]

If I start my PIXI project by loading some 'png' resources I need to do 

loader.add(...).load(setup);
function setup(loader, resources) {
    //...
}

But what if I don't need those resources to start my project? I am currently using:

window.onload = function() {
    //...
}

Is this the right way to do or is there any other more PIXI-ish way?

There is not a more pixi-ish way. You start your project whenever you want it to be started. Usually after the DOM has loaded.
