POHow to create custom MouseEvent.CLICK event in AS3 (pass parameters to function)?
text
Body
copied!<p>This question doesn't relate only to MouseEvent.CLICK event type but to all event types that already exist in AS3. I read a lot about custom events but until now I couldn't figure it out how to do what I want to do. I'm going to try to explain, I hope you understand:</p> <p>Here is a illustration of my situation:</p> <pre><code>for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, doSomething); } function doSomething(e:MouseEvent){ /* */ } </code></pre> <p>But I want to be able to pass <em>someVar</em> as a parameter to <em>doSomething</em>. So I tried this:</p> <pre><code>for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, function(){ doSomething(someVar); }); } function doSomething(index){ trace(index); } </code></pre> <p>This kind of works but not as I expect. Due to the function closures, when the MouseEvent.CLICK events are actually fired the <em>for</em> loop is already over and <em>someVar</em> is holding the last value, the number <em>9</em> in the example. So every click in each movie clip will call <em>doSomething</em> passing <em>9</em> as the parameter. And it's not what I want.</p> <p>I thought that creating a custom event should work, but then I couldn't find a way to fire a custom event when the MouseEvent.CLICK event is fired and pass the parameter to it. Now I don't know if it is the right answer.</p> <p>What should I do and how?</p>
