AS3 Signals Bubbling note

Sunday, March 07th, 2010 | Author: dehash

Working with this now and just a note that it looks like a way to bubble Signals from a nested display class is as follows:

public var deluxeSignal:DeluxeSignal = new DeluxeSignal(this);
…
deluxeSignal.dispatch(new GenericEvent(true));

and the listening class further up the display list implements IBubbleEventHandler and requires the following method:

public function onEventBubbled(e:IEvent):void {
trace(e +"-"+ e.target +"-"+ e.currentTarget +"-"+ e.signal);
}
- – -
Added a quick example below with source code using the current signals release unedited
here

PS there is an excellent Signals video tutorial here

- – -
Update: Added a new version of the simple example that works with the latest Signals release (0.7). The onEventBubbled method now has a boolean return value to determine whether to continue bubbling or stop.
The new example code can be downloaded here

- – -

Some ideas on passing parameters:
var deluxeSignal:DeluxeSignal = new DeluxeSignal(this);
deluxeSignal.dispatch(new GenericEvent(true));
Here you are passing “this”, ie the sending instance, as the GenericEvent event target so that it is available as the event.target within onEventBubbled(event:IEvent).

Alternately pass in a Value Object (VO) instead of “this” to pass more precise and data typed parameters (you would need to give it a “parent” property) or another option is to extend GenericEvent and give it some custom properties which can be read within onEventBubbled.

Quick test of FCSS

Sunday, February 14th, 2010 | Author: dehash

fcss test Spent an hour testing the cool Flash AS3 FCSS library. Seems fine to set any public property so it can trigger tweens, image loads, filters etc as in this example
There is a good FCSS video tutorial here

Trees image from here released under CC license


Code below all in one file for now as it was just a quick test. Aside from FCSS it also uses three other AS3 libraries - Tweener and MinimalComps and BumpSlide

You can view the swf here

Flash CS4 Papervision example

Tuesday, April 07th, 2009 | Author: dehash

This post is mainly to cover some of the questions often asked and give a simple download to try out.

The Papervision examples here were compiled using the Flex SDK and FlashDevelop so there are no .fla's used. But as the examples are AS3 classes the conversion to using in Flash can be made so here is one download with a few usage ideas.

It was made in Flash CS4 and can be viewed here and the source can be downloaded here. It uses the very simple PlaneDemo class without editing it and the recent Papervision classes Papervision3D_2.0.883.zip from here are included in the zip.

Some things to note:
- The first line of the PlaneDemo class is
package com.dehash.pv3d.examples.basic
so the PlaneDemo class is stored in the following location
com/dehash/pv3d/examples/basic/PlaneDemo.as

- PlaneDemo.as is used as the document class and set in the Publish Properties pane which is one of the ways to use the class in Flash because PlaneDemo extends BasicView which extends AbstractView which extends Sprite.

- the Papervision classes are stored in the libs folder and that directory is added to the Source path using the Publish Settings > Flash tab path > Settings dialogue.

PlaneDemo.as includes the following Metadata
[SWF(width="800", height="600", backgroundColor="0xffffff")]
Flash CS4 is able to read this and implement it whereas the CS3 IDE was not. There is an article that covers this here

At some point I shall put up a more interesting example than PlaneDemo but it does cover many of the essentials despite being quite basic. The pop up view of the swf is displayed using shadowbox.

More Papervision 3D examples with source code

Sunday, January 04th, 2009 | Author: dehash

Added some more Papervision 3D examples with source code.

There are now over 30 and all examples use current Papervision3D GreatWhite from SVN and so far all use BasicView also
