pv3d.org - Papervision3D Tutorials

hi.

works great, but I’d like to see some examples of interactivity with planes. In previous version of pv I could add listener to plane.container, but in 2.0 version there is no container prop. How can I make plane clickable?

cheers

thanx. this seems to be much more intuitive than previous version. how’s about setting custom alpha to an object like: plane.alpha=.5 ?

I’m investigating source code but…

woow. changing value of a texture properties affects a plane. And if I have MovieMaterial I can store all interaction inside a class which is an asset.

var mc:Mc=new Mc()
material = new MovieMaterial(mc);
material.animated = true;

//inside class Mc
public function onMouseOver(ev:Event):void{ Tweener.addTween(this,{alpha:.2,time:2})
}

that’s the way I like it

thanx for this

hey!, i know this is a bit delayed - but i was wondering about where the specific freecamera3dcontroller class is located at the blitz site? i cant seem to find it at the moment.

cheers.

ha! cheers john - i actually went through all the blitz sample files and finally found it - so far so good -

buuuut - the file goes “1119: Access of possibly
undefined property container through a reference with static type org.papervision3d.scenes:Scene3D.”

in the output for all this bit:

public function FreeCamera3DController(camera:FreeCamera3D,scene:Scene3D){
this.camera = camera;
this.scene = scene;
*scene.container.stage.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownEvent);
*scene.container.stage.addEventListener(MouseEvent.MOUSE_UP,mouseUpEvent);
*scene.container.stage.addEventListener( KeyboardEvent.KEY_DOWN, keyDownEvent );
*scene.container.stage.addEventListener( KeyboardEvent.KEY_UP, keyUpEvent );
*scene.container.addEventListener(Event.ENTER_FRAME,enterFrameEvent);
}

protected function mouseDownEvent(event:MouseEvent):void{
*scene.container.stage.addEventListener(MouseEvent.MOUSE_MOVE,mouseMoveEvent);
*startPoint = new Point(scene.container.mouseX,scene.container.mouseY);
*startRotationY = camera.rotationY;
*startRotationX = camera.rotationX;
}

protected function mouseMoveEvent(event:MouseEvent):void{
*targetRotationY = startRotationY - (startPoint.x - scene.container.mouseX) / 2;
*targetRotationX = startRotationX + (startPoint.y - scene.container.mouseY) / 2;
}- though

sorry for the length - is it something to do with the freecamer3dcontroller.as file not being able to find the default classes?

sorry if this is long winded…
and cheers for replying so quickly..

gaa! dbl post sorry.

thanks, john got it working perfectly - though another question relating to it - in the previous version 1.9 (phunky i think) you didn’t have to declare/import the ‘viewport3d’ instead just put it into a new container i.e:

[code]
var container:Sprite = new Sprite()
addChild(container);
container.x = stage.stageWidth* .5;
container.y = stage.stageHeight * .5;
[/code]

i would then pas this into the scene3d…
[code]
var scene:Scene3d = new Scene3d(container, true)
[/code]

i wanted to do the same thing in version 2.0 (great white).
so i can import the whole papervision Sprite to (for example) frame one of my .fla - or any other spot - as it currently always infront/obscuring any graphics in my scene

not sure what i would do in this case..

private function initPapervision():void
{
viewport = new Viewport3D();
addChild( viewport );

scene = new Scene3D();
camera = new FreeCamera3D();

renderer = new BasicRenderEngine();

cheers, alex

create a Sprite Containeur, addChild this sprite on the stage;

then addChild the viewport on the sprite ;

private function initPapervision():void
{
var spriteContaineur:Sprite = new Sprite();
addChild(spriteContaineur);
viewport = new Viewport3D();
spriteContaineur.addChild( viewport );

scene = new Scene3D();
camera = new FreeCamera3D();

renderer = new BasicRenderEngine();
…

after it , all new DisplayObjects you will add on the stage will be above the pv3d Scene;

ahhh~ just what i needed
1 extra Q, how to stop the action of camera when it reach a limit? Cause the code now if i keep on pressing the camera will be moving like forever~
