TweenEvent : Basic Tweening

For all the beginning Flashers (Flash AS 3.0) ,

here’s a little post how to make a tween using the standard Tweening Class in Flash CS3 (not yet the Tweener class: that’s for later… , let’s just first give a little info before using this open-source tweening Class)

The Tweenables class provides constant values for the names of animation properties used in the Motion and Keyframe classes.

A tween is writen as following

var tweenName = new Tween([attribute],”[constant]“,[kind of tween],[from value],[to value],[time],[true: use second, False: use frames]);

Attribute: a movieclip, button

Constant: wich sort of movement … [ALPHA, ROTATION, SCALE_X, SCALE_Y, SKEW_X,SKEW_Y, X , Y, WIDTH and HEIGHT]

From Value: from value (also possible the attribute.x, attribute.y, attribute.alpha …… , to get the absolute value of a object )

To Value: from value (also possible the attribute.x, attribute.y, attribute.alpha …… , to get the absolute value of a object )

Kind Of Tween: how is the tween motioned…

True/False: True: use seconds, False: use keyframes ( this is the tweening time taken… )

Now having discussed the variables of a tween , let’s make a simple tween, asume we have a movieclip on our stage with instance name: box_mc, let’s make a new tween wich enables to fade the box_mc from nothing to alpha 1….

var TweenFadeIn = new Tween(box_mc,”alpha”,Bounce.easeInOut,0,1,1,true);

var TweenFadeIn = new Tween(box_mc,”alpha”,Bounce.easeInOut,box_mc.alpha,1,1,true);

Both tweens fill do the same IF we have set the alpha of our box_mc to 0 when starting up….

If we have not , than the difference is that the first tween wil reset the alpha of our box_mc to 0 before executing this tween… With the second tween , we will take the actual alpha value of the box_mc at the moment of executing ….

For whom who haven’t met the Tweener Class , please, please, please …. do SO!

The tweening possibilities have reached another level, Test & Learn, ….

The Barbecue , Part I

A new day in the history of school projects….

Using the Adobe Master Collection CS 3.0 , we have to build a productsite with a given subject…

My subject: THE BARBECUE…

After taking a good look , i figured out taking my home barbecue would be the best route to succes, why?

I can use my own as model…

No time to waist searching google, or other URL’s for usefull photo’s, i just take my own…

Today i started with Part I of the project, the taking photo’s and photoshopping them…

The first 3 freshly ctrl + s’ed

We’ll Keep in touch…

That’s Right…

KeyBoard Events

This little tut shows you how to capture keyboard events…

First we will need to add a eventlistener to the stage, with the folowing function: downHandler …

stage.addEventListener(KeyboardEvent.KEY_DOWN, downHandler);

function downHandler(evt:KeyboardEvent):void{

trace(evt);

}

Like you see we trace the KeyBoardEvent, …

This will give something like this:

Using the keyCode attribute we can check witch key is pressed…

Example, if the left arrow key is pressed we want to trace a little message… , this we do inside the downHandler, a other okace in the actionscript code wouldn’t recognize these keyCodes….

function downHandler(evt:KeyboardEvent):void{
if(evt.keyCode == 37){
trace(“Arrow Left”)
}
}

Roads are endless, but with this little introduction , the road is now under you feet….

You can chose how far you tend to go…
