Simple actionscript 3.0 dynamic registration point

this is a very simple dynamic registration point in actionscript 3.0 using fl.motion.MatrixTransformer class. please refer the class for more useful features.

import fl.motion.MatrixTransformer;
import flash.display.Sprite
var box:Sprite;
box = new Sprite();
box.graphics.beginFill(0xFF0000);
box.graphics.drawRoundRect(0, 0, 100, 100, 5);
addChild(box);
box.x = (stage.stageWidth / 2);
box.y=stage.stageHeight/2;
var xPoint:uint =  (box.width/2);
var yPoint:uint =  (box.height / 2);
var mtrx:Matrix=box.transform.matrix;
MatrixTransformer.rotateAroundInternalPoint(mtrx, xPoint, yPoint, 40);
MatrixTransformer.setScaleX(mtrx,2)
box.transform.matrix=mtrx;

Simple custom event example actionscript 3.0

This is a simple custom Event example I hope this will help actionscript 3.0 bingers to understand how event works in actionscript 3.0. In this example I just created a MouseDown event listener for stage mouse clicks. Clicking the stage will trigger the custom event.

const CUSTOM_EVENT:String='custom_event';
addEventListener(MouseEvent.CLICK,onMouseClick);
function onMouseClick(e:Event){
    dispatchEvent(new Event(CUSTOM_EVENT));
}
addEventListener(CUSTOM_EVENT,onCustomevent)
function onCustomevent(e:Event){
    display.text="Custom Event Called"
}

how to access maintimeline functions and variables from a nested movieclip in as3

This is the biggest problem for actionscript coders those who migrate from actionscript 2.0 and actionscript 1.0 to actionscript 3.0. In as1,as2 we can access the main timeline functions and variables from a nested movieclips just using _root.varName or _root.functionName, But in as3 we cant access the maintimline variables and functions this way.following is a sample code to access the maintimeline variable and functions from a nested movieclip.

MovieClip(root).functionName();
Or
MovieClip(root).varName

What is bubbles property in Actionscript 3.0 Event ?

When an event occurs, it moves through the three phases of the event flow: the capture phase, which flows from the top of the display list hierarchy to the node just before the target node; the target phase, which comprises the target node; and the bubbling phase, which flows from the node subsequent to the target node back up the display list hierarchy.

AS3 button click events vs As2 button click events example

this is a simple button tutorials for As3 beginners.

A simple As2 buttonClick

on(press){

trace("Clicked");

}


Or

[button].onPress=function(){

trace("clicked");

}

In as3

simple one

[button].addEventListener(MouseEvent.CLICK,function(){trace("clicked")});

or

function buttonClick(evt:MouseEvent) {

trace("clicked");

}

[button].addEventListener(MouseEvent.CLICK,buttonClick);


so what is in "evt:MouseEvent"?. just try this one

function buttonClick(evt:MouseEvent) {

trace(evt.target.name);

}

[button].addEventListener(MouseEvent.CLICK,buttonClick);

This event has the following properties:

Property	Value
bubbles	true
buttonDown	true if the primary mouse button is pressed; false otherwise.
cancelable	false; there is no default behavior to cancel.
ctrlKey	true if the Control key is active; false if it is inactive.
currentTarget	The object that is actively processing the Event object with an event listener.
localX	The horizontal coordinate at which the event occurred relative to the containing sprite.
localY	The vertical coordinate at which the event occurred relative to the containing sprite.
shiftKey	true if the Shift key is active; false if it is inactive.
stageX	The horizontal coordinate at which the event occurred in global stage coordinates.
stageY	The vertical coordinate at which the event occurred in global stage coordinates.
target	The InteractiveObject instance under the pointing device. The target is not always the object in the display list that registered the event listener. Use the currentTarget property to access the object in the display list that is currently processing the event.
