<h2>pixi-action</h2>    <p>pixi-actionis a plugin forPixi.js to create actions and animations easily. API inspired by <strong>Cocos2d-x</strong> .</p>    <h2>1. Install</h2>    <p>npm install pixi-action</p>    <p>require it, or import it with script tag, all is OK.</p>    <h2>2. Usage</h2>    <p>Code just like below.</p>    <pre>  var renderer = new PIXI.autoDetectRenderer(800,600);  document.body.appendChild(renderer.view);  var stage = new PIXI.Container();    var sprite1 = new Sprite(resources['res/img/animal.png'].texture);    var action_move = PIXI.action.MoveTo(500, 400, 2);    var animation = PIXI.actionManager.runAction(cat, action_moveto);  animation.on('end', function(elapsed) {    console.log('action end.');  });    function animate() {    window.requestAnimationFrame(animate);    renderer.render(stage);    PIXI.actionManager.update(); // update actions  }  animate();</pre>    <h2>3. How it works</h2>    <p>This plugin add a new namespace named <strong> action </strong> to the PIXI namespace, and the action namespace has 2 new classes, <strong>ActionManager</strong> and <strong>Action</strong> , and create an instance for ActionManager in PIXI.actionManager, but all you need is add PIXI.actionManager.update() in your requestAnimationFrame. You can pass as params for PIXI.actionManager.update(delta) your own delta time, if you don't pass anything it will be calculated internally.</p>    <p>For max accuracy calculating the delta time you can use theAnimationLoop plugin.</p>    <p>When a action is started, or ended, it will fire events named start / end .</p>    <h2>4. Using AnimationLoop</h2>    <pre>  var renderer = new PIXI.autoDetectRenderer(800,600);  document.body.appendChild(renderer.view);    var animationLoop = new PIXI.AnimationLoop(renderer);    //Add a postrender or prerender event to add the timer.update in the raf.  animationLoop.on('postrender', function() {    PIXI.actionManager.update(this.delta); //Pass as param the delta time to PIXI.timerManager.update  });    animationLoop.start();</pre>    <h2>5. Events</h2>    <p>TimerManager extends from PIXI.utils.EventEmitter , and emit some events: start, end, repeat, update and stop. More info: Node.js Events</p>    <ul>     <li><strong>start - callback(elapsedTime)</strong> : Fired when the action starts.</li>     <li><strong>end - callback(elapsedTime)</strong> : Fired when the action is ended.</li>    </ul>    <h2>6. Actions & Animations</h2>    <p>Now <strong>pixi-action</strong> supported actions / animations below. You can just combine them for complex actions.</p>    <ul>     <li><strong>ActionMove</strong></li>    </ul>    <p>PIXI.action.MoveTo(x, y, time); PIXI.action.MoveBy(x, y, time);</p>    <ul>     <li><strong>ActionScale</strong></li>    </ul>    <p>PIXI.action.ScaleTo(scale_x, scale_y, time); PIXI.action.ScaleBy(scale_x, scale_y, time);</p>    <ul>     <li><strong>ActionRotate</strong></li>    </ul>    <p>PIXI.action.RotateTo(rotation, time); PIXI.action.RotateBy(rotation, time);</p>    <ul>     <li><strong>ActionBlink</strong></li>    </ul>    <p>PIXI.action.Blink(count, time);</p>    <ul>     <li><strong>ActionFade</strong></li>    </ul>    <p>PIXI.action.FadeIn(time); PIXI.action.FadeOut(time);</p>    <ul>     <li><strong>ActionSkew</strong></li>    </ul>    <p>PIXI.action.SkewTo(x, y, time); PIXI.action.SkewBy(x, y, time);</p>    <ul>     <li><strong>ActionPivot</strong></li>    </ul>    <p>PIXI.action.PivotTo(x, y, time); PIXI.action.PivotBy(x, y, time);</p>    <ul>     <li><strong>ActionJump</strong></li>    </ul>    <p>PIXI.action.JumpTo(x, y, time); PIXI.action.JumpBy(x, y, time);</p>    <ul>     <li><strong>ActionTint</strong></li>    </ul>    <p>PIXI.action.TintTo(tint, time); PIXI.action.TintBy(tint, time);</p>    <ul>     <li><strong>ActionSequence</strong></li>    </ul>    <p>PIXI.action.Sequence(actions);</p>    <ul>     <li><strong>ActionRepeat</strong></li>    </ul>    <p>PIXI.action.Repeat(action, count);</p>    <ul>     <li><strong>repeatForever</strong></li>    </ul>    <p>PIXI.action.Repeat(action);</p>    <ul>     <li><strong>ActionDelay</strong></li>    </ul>    <p>PIXI.action.Delay(time);</p>    <h2>7. API</h2>    <ul>     <li><strong>PIXI.actionManager.runAction(object, action)</strong> : run action on an object, return an animation, can on the events.</li>     <li><strong>new PIXI.action.*(args)</strong> : create an action.</li>    </ul>    <p> </p>    <p> </p>    <p> </p>
