lee's Papervision3D tutorial

G'day guys

I have been playing around with Lee's tutorial for papervision - very cool!!
Have got it zooming in and out with the mouse wheel and alpha.
But not having much luck with a button press/click.
I can get a click to register but because I think I am out of scope of the loop it only registers the last object. I can get a trace to tell me the number of each object but cannot target it.

Code: Select all

import flash.system.fscommand;
fscommand("fullscreen", "true");
fscommand("allowscale", "false");


import org.papervision3d.scenes.*;
import org.papervision3d.cameras.*;
import org.papervision3d.objects.*;
import org.papervision3d.materials.*;


var container:Sprite = new Sprite();
container.x = stage.stageWidth * 0.5;
container.y = stage.stageHeight * 0.5;
container.scaleX = container.scaleY = 2;

addChild(container);
trace(container.scaleX);

var scene:Scene3D = new Scene3D(container);
var camera:Camera3D = new Camera3D();

camera.zoom = 2;

var bam:BitmapAssetMaterial = new BitmapAssetMaterial("surf");

bam.oneSide = false;
bam.smooth = true;

for(var i:uint; i < 50; i++){
   var p:Plane = new Plane(bam, 100, 100, 2, 2);
   scene.addChild(p);
   p.x = Math.random() * 600 - 350;
   p.y = Math.random() * 600 - 350;
   p.z = Math.random() * 600 - 350;
   p.rotationY = Math.random() * 360;
   ["null"+i]addEventListener(MouseEvent.CLICK, clicked);
   trace(["null"+i])
}

function clicked (event:MouseEvent):void {
   trace("clicked= "+["null"+i]);//"this" without the quotes does not work
   }



this.addEventListener(Event.ENTER_FRAME, render);

function render(e:Event):void{
   camera.x = stage.mouseX - (stage.stageWidth * .5);
   camera.y = stage.mouseY - (stage.stageHeight * .5);
   camera.z = stage.mouseY - (stage.stageHeight * .05);
   //trace(container.scaleX);
   scene.renderCamera(camera);
}




Maybe I have to wrap it in another movie clip/sprite but I am not sure how to.
Any ideas?
Have uploaded the swf if you would like to see the zoom. (zip as it is quite large)

easy

I'll use this post to make a question about the tutorial.

What does the final bunch of traces mean? Is it normal with papervision?

try this

Code: Select all

var pArray:Array = new Array():

for(var i:uint; i < 50; i++){
   var p:Plane = new Plane(bam, 100, 100, 2, 2);
   p.name = i // just give it a name
   pArray.push(p); // store it in an Array!
   scene.addChild(p);
   p.x = Math.random() * 600 - 350;
   p.y = Math.random() * 600 - 350;
   p.z = Math.random() * 600 - 350;
   p.rotationY = Math.random() * 360;
   ["null"+i]addEventListener(MouseEvent.CLICK, clicked);
   trace(["null"+i])
}

function clicked (event:MouseEvent):void
{
   trace("clicked= "+["null"+i]);//"this" without the quotes does not work
        for(var j:uint; j < 50; j++)
       {
            if (event.target == pArray[j])
               {
                   trace(event.target.name + " was clicked");
                }
       }
}

I got the idea from TODD!

one more thing change the addeventlistener

Code: Select all

p.addEventListener(MouseEvent.CLICK, clicked);

hope it works!

Thank you AlfonsoM

I was searching through the classes and came across a name parameter which defaulted to null but could not work out how to incorporate it. I think that is why null showed up in the trace results. Their are a few classes that perform similar tasks and was not sure if I had to import a different class for mouse events.

Now to do something with it!!

Maybe the forum could set aside a section for papervision?

All the best

Maybe the forum could set aside a section for papervision?

Well, the problem with that is by the time we create a forum for every aspect of Flash/Flex/AIR and whatnot, we'll have 200 forums to barrel through. While it seems at first like a good way to get "organized", there is a point where too much can be a bad thing.

Also, at this point, there really isn't a lot of demand for it. Of course, that could very well change in the future...

look at the papercloud example provided by carlos along with his api. he adds click functionallity there.

How did you people get it to work? I have tried to using:

p.addEventListener(MouseEvent.CLICK, buttonPressed);

but the p isnt a sprite and thus doesnt listen to mouse events, or am I geting something wrong? Do any one have a link to a working example?

You have to add the listener to the container not the sprite.

p.container.addEventListener....

and use Dictionary instead of Array, its easyer, but thats your choice.

Here is my part of source, hope it helps.

private var planesContiner:Dictionary = new Dictionary();

private function createMyPlanes():void{
for(var i:int = 0; i<10; i++){
var p:Plane = new Plane(bit,200,200,4,4);
p.x = Math.floor(Math.random()*1000-500);
p.y = Math.floor(Math.random()*1000-500);

scene.addChild(p);

p.container.addEventListener( MouseEvent.CLICK, rollOverObject );

planesContiner[ p.container ] = p;
}
}


// fucntion to grab the plane and do what you want with it
private function rollOverObject(event:MouseEvent):void{

var Myplane:Plane = planesContiner[ event.target ]; //thats the instance of your plane

TweenLite.to(Myplane,0.7,{rotationX:0,rotationY:0});

}
