Requirements Prerequisite knowledge You should be familiar with ActionScript 3 syntax, data types, and variables. The effect can be achieved in a relatively short space of time and with very little code.", "maginfy.jpg", "http://flash.tutsplus.com/tutorials/effects/create-an-impressive-magnifying-effect-with-actionscript-30/#more-354" ); } It's messy, but it's really the same thing. It centralizes the code so that all of it is placed in a specific place that can be easily updated without having to manually modify each time the code is used. Second, defined functions exist throughout the scope in which they are defined, including in statements that appear before the function definition. http://stackoverflow.com/questions/14425806/error-1170-function-does-not-return-av-value

The image variable, on the other hand, is declared in the main body of the script, so it persists from function call to function call. For example, the following code generates an error in strict mode, because it does not return a valid value: function doubleNum(baseNum:int):int { trace("after return"); } Nested functionsYou can nest functions, which A function marked override must exactly match the parameter and return type declaration of the function it is overriding. In mathematics, a function takes a single value and produces a related single value.

  1. For example: trace("The sine of 45 degrees is " + degSin(45)); What if we don't return a value, like in our log function?
  2. Remember, a function can be thought of as a named task.
  3. If a method in a class overrides a method in a base class, you must explicitly declare it by using the override attribute, as this example shows: public override function foo():void{};
  4. Version2 Version2 Member since: Sep. 24, 2003 Offline.
  5. If you want to try it, just remove the parentheses, leaving the function name by itself and run the movie.
  6. The operand must be a variable, an element in an array, or a property of an object. 1107Increment operand is invalid.

Method signatures must match exactly. 1145Native methods cannot have a body. How to book a flight if my passport doesn't state my gender? I could use some help with this please. [Writing 2.0 ][Mr. Is it possible to write a function template which returns whether the number of arguments is divisible by N?

I was able to reduce that function down to return this['floorArr' + theBldg]; I didn't know you could do that, lol. For example, the trace() function is a top-level function in ActionScript 3. An interface can only extend another interface. 1143The override attribute can only be used on a method defined in a class.1144Interface method %s in namespace %s is implemented with an incompatible The value used to initialize the constant is either undefined or could have different values at run time.

Any error about a "string literal" normally means you are missing a quote.  Strings are always wrapped in quotes like this: "flash".  If you forget a closing quote, you'll see an Acknowledgement The content in this article is based on material originally published in the Learning ActionScript 3 user guide created by Adobe Community Help and Learning. Any statements written after a return statement are not executed, as follows: public function doubledValue(baseNum:int):int { return (baseNum * 2); trace("after return"); // This trace statement will not be executed. } Newgrounds.com — Everything, By Everyone.

Two different names are used to distinguish where the data is. http://www.adobe.com/devnet/actionscript/learning/as3-fundamentals/functions.html For example, the following defines the function topLevel() to print the word "top". It's not that bad; you know not to freak out when you see the following listing, which replaces our previous block of onButtonNClick functions: function onButton1Click(event:MouseEvent):void { setContent("Create an Impressive Magnifying First, you can call the method using square brackets ( [] ) instead of the dot ( . ) operator.

This is actually a very useful technique, which is why you have to go to the extra step to actually call the function. this page I reinstalled flashdevelop, but I'm still not able to use the .swc. It's important to note that parameters are really just variables. This starts to get into the topic of scope, which can be hard to grasp, so we'll stop talking about this here.

Using the var keyword inside a function will lead to the creation of a local variable that will not be accessible outside the function. Then I’ll explain how to add interactivity to the elements and set up a basic pong game. The code you downloaded. get redirected here I then added the two lines of code to my main class and got this: import com.newgrounds.*; //1172: Definition com.newgrounds could not be found.

I've done this, exactly. Estimated availability date is subject to change. You are either calling a private method from another class, or calling a method defined in a namespace that is not in use.

Team Up!

Likewise, it is in theory possible to build a complete application that doesn't once use a function (although this is actually very difficult in ActionScript, for an application of any useful In fact, it is this default value mechanism that is what makes a parameter optional. Then again, sometimes you want the variable to persist, in which case you might wonder why the value you're setting in a function isn't available outside of the function. A reference might be to more than one item.

Adding a button would involve: Adding another instance of the button movie clip, with a new label Setting up its click handler Setting the headline text Setting the body text Loading The rules for naming a function are the same as the rules for naming variables: alphanumeric characters, the underscore and the dollar sign are the only characters allowed and the name If you want, you can always type in your own, less intense data to get practice in the concepts, then copy and paste when you feel you've got it. useful reference Force Microsoft Word to NEVER auto-capitalize the name of my company Yes, of course I'm an adult!

Here is how your codes should look: public function get(_bulletT:String):String { for (var i:int = 0; i < _bulletT.length; i++) { if (_bulletT.charAt(i) == "star") { return "star"; } } return Least Common Multiple How to pluralize "State of the Union" without an additional noun? If you would like to have your variable accessible outside you function you will have to define it outside the function and then simply modify it from inside the function: var The following full script: function log(message) { trace("Log: " + message); } log("This isn't just a trace, it's a log."); log("Here we go again."); Results in two traces to the Output

FD is a simple program, I was saying you should just explore it and figure out what's wrong. I'm not sure what this compilation command is you're talking about, is it this? [Writing 2.0 ][Mr. Since we are loading images with ActionScript, we'll go ahead and create a Loader with ActionScript, as well. The method cannot be extended because it is marked as final in the base class. 1026Constructor functions must be instance methods.1027Functions cannot be both static and override.1028Functions cannot be both static
