This example will show you how to make an animated node a Drop target.

Setting up the HTML

First we will create our HTML.

``` {{>anim-drop-source-html}} ```

Now we give that HTML some CSS to make it visible.

``` {{>anim-drop-source-css}} ```

Setting up the YUI Instance

Now we need to create our YUI instance and tell it to load the dd-drop, dd-plugin, dd-drop-plugin and anim modules.

``` YUI().use('dd-drop', 'anim', 'dd-plugin', 'dd-drop-plugin'); ```

Making the Node draggable

Now that we have a YUI instance with the modules loaded, we need to instantiate the Drag instance on this Node.

In this example we will be using Node plugins to accomplish our tasks.

``` YUI().use('dd-drop', 'anim', 'dd-plugin', 'dd-drop-plugin', function(Y) { //Get the node #drag var d = Y.one('#drag'); d.plug(Y.Plugin.Drag, { dragMode: 'intersect' }); }); ```

Animating the Nodes

Now we will set up the Animation sequence that we want to run.

``` //Get all the div's with the class anim var anims = Y.Node.all('div.anim'); var counter = 0; anims.each(function(v, k, items) { //Get a reference to the Node instance var a = v; counter++; //Add the FX plugin a.plug(Y.Plugin.NodeFX); //Add the Drop plugin a.plug(Y.Plugin.Drop); //Set the attributes on the animation a.fx.setAttrs({ from: { left: 0 }, to: { curve: function() { var points = [], n = 10; for (var i = 0; i < n; ++i) { points.push([ Math.floor(Math.random()*Y.DOM.winWidth() - 60 - a.get('offsetWidth')), Math.floor(Math.random()*Y.DOM.winHeight() - a.get('offsetHeight')) ]); } return points; } }, //Do the animation 20 times iterations: 20, //Alternate it so it "bounces" across the screen direction: 'alternate', //Give all of them a different duration so we get different speeds. duration: ((counter * 1.75) + 1) }); }); ```

Making the Node a Target

Using the dd-drop-plugin, we now need to make this animated Node a Drop Target.

To do that, we need to add the plugin after the fx plugin.

``` //Add the FX plugin a.plug(Y.Plugin.NodeFX); //Add the Drop plugin a.plug(Y.Plugin.Drop); ```

Syncing the Target with the Animation

The Drop Target needs to be in sync with the animation, since we are changing the height, width, top and left style.

We do this by adding a listener to the tween event on the animation instance.

``` //on tween of the original anim, we need to sync the drop's shim. a.fx.on('tween', function() { //Do we have an active Drag? if (Y.DD.DDM.activeDrag) { //Size this shim this.drop.sizeShim(); //Force an over target check since we might not be moving the mouse. Y.Lang.later(0, a, function() { this.drop._handleTargetOver(); }); } }, a); ```
