<h1>Application</h1>
<p>
The class PIXIApp is the main entry point to create a new PIXI Application.
It inherits from PIXI.Application, set meaningfull defaults, creates a scene and
a stage and provides some helper methods to load resources, get the size of
the app...
</p>
<p>
The pattern to create a new application is:
<ol>
<li>Create a new PIXIApp Object</li>
<li>Call the setup() method</li>
<li>Call the run() method</li>
</ol>
These three steps are required. The constructor has been split into these three parts in order to have the greatest possible flexibility in complex applications.
The setup() method creates a default scene. This can be overwritten with a spezialized setup() method to create a scatter container, for example.
</p>
<p><a href="../../doc/out/PIXIApp.html">JavaScript API</a></p>
<p>Let's look at an example of creating a new application:</p>
<canvas id="canvas" class="interactive"></canvas>
<p>
What you should see: There should be a green circle on a dark background. In the upper left corner, the refresh rate should be approximately 60 fps.
</p>
<script class="doctest">
const app = new PIXIApp({
view: canvas,
width: 450,
height: 150,
fpsLogging: true,
transparent: false
})
app.setup()
app.run()
let highlightBtn = new PIXI.Graphics();
highlightBtn.lineStyle(2, 0x033792);
highlightBtn.drawRoundedRect(15, 40, 30, 30, 10);
highlightBtn.endFill();
app.stage.addChild(highlightBtn);
// app.loadSprites("assets/app-circle.png", sprites => {
// let circle = sprites.get("assets/app-circle.png")
// circle.anchor.set(0.5)
// circle.x = app.screen.width / 2
// circle.y = app.screen.height / 2
// circle.width = 80
// circle.height = 80
// app.scene.addChild(circle)
// app.run()
// })
</script>
