//text.js above main.js in my index.html
var e = function() {

var style = {
    font : ' 36px Luckiest Guy',
    fill : '#F7EDCA',
    dropShadowColor : '#000000',
    dropShadowAngle : Math.PI / 6,
    dropShadowDistance : 6,
    //wordWrap : true,
   //wordWrapWidth : 1000,
    //LineHeight : 4,
};

e.body = new PIXI.Text('level ',style)
e.body.anchor.x=.5
e.body.anchor.y=.5
e.body.x=50
e.body.y=100

}

//main.js below text.js in my index.html

var stage = new PIXI.Container();
var interactive=true
stage.interactive =true ;	

// create a renderer instance
var renderer = PIXI.autoDetectRenderer(320, 480);

// add the renderer view element to the DOM
document.body.appendChild(renderer.view);

requestAnimationFrame( animate );

var hud = e()

stage.addChild(hud);

function animate() {

	requestAnimationFrame( animate );

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

Hi, i don't knwo how to set correctly my text.js to be used as a OOP object. 

I can't see my text who is hud in my main.js....why ?

I take the example of a text but it could be a rectangle or something else...

Thanks for your response.
