Flash/ActionScript: Create an Array of Objects from a Unique Class

When starting in AS2, I found it difficult to make an array of objects after creating my own class. Hopefully, this little tutorial will make it easier for others.

I spent eight hours trying to figure this out initially. To me, actionscript handles this a little differently from other programming languages.

Basically, we will create a small class, then create an object with that class, and load that object into an array.

First, we create our class. Remember, to create a class, you have to do it from a separate actionscript file.

class testClass
//Establishes the first variable in your testClass
public var first: String;

Now, here is the heavily commented code that should be in your main actionscript file.

//Import your unique class--testClass
import testClass;

//create tC object from your test class

//create an array to hold the objects
var theArray:Array = new Array();

//create loop with i as the counter
for (var i=0; i<4; i++) { //create tC object from your test class var tC:testClass = new testClass(); //assign text to the first variable. //i included to prove that we are assigning different data //to each object in the array tC.first = "asdf" + i; //asdf0, asdf1, etc. //push the object into the array theArray.push(tC); } //Another loop with ii as counter for (var ii=0; ii<4; ii++) { //shows that the array contains an array of objects //and demostrates how to extract the values from them trace (theArray[ii].first); //asdf0,asdf1, etc. }

This rather simple tutorial should prove helpful.
