Question

After an object has been added to an array via push(), how can you reference the x or y value of it? For example:

var Test:Sprite = new Sprite();         
Test.graphics.beginFill(0x000000);
Test.graphics.drawRect(0,0,10,10);
testHolder.addChildAt(genericBlock,0);

Answer 1

The x and y values of any object stored in an array can be accessed via:

var myArray = new Array();
myArray.push(testSprite1); // First object 'pushed' into array at position 0
myArray.push(testSprite2); // Second object 'pushed' into array at position 1

myArray[0].x = 50; // testSprite1.x = 50
myArray[1].x = 100; // testSprite2.x = 100;

// To referece..
trace(myArray[0].x, myArray[1].x); // Outputs: 50 100

This is a great tutorial to learn how to implement arrays and manipulate all/single elements held within them:
