Panorama Viewer


*FIXED!!*

Here's a really simple example, all it does is texture a sphere and rotate it depending on what the camera is doing:

You can use this for pretty much any panoramic image, just change the image url and tweak it a bit :)

11. Advanced Interactivity 2


This tutorial will show you how to handle full interactivity on an objects surface, just as if it's a normal movieclip.

For my example, I've made this. The red spot in the centre is a button. You can click it to toggle it's glow on and off. The other button will reveal how it works!

There are other ways to do this, but I think this way is the easiest and most hassle-free, and it's pretty fast.

I've super-commented the source code, so from reading the comments in the code you should be able to figure out exactly what's going on.

The basic idea is, you add the movie clip which is being used as the texture to the scene, but make it invisible. You then move it so that your mouse is over the correct part of the movieclip, when your mouse touches the texture on the 3d model. I think the "Show Movieclip" button on the cube above will explain better than I can :)

We Have Forums


We have forums!

I've set up a Papervision 3d forum at http://papervision2.com/forum/

Hopefully these forums will help everyone to solve common problems that they're having with Papervision. I'm going to fill them with some problems which we've resolved in the past so they're all in one place.

I've set up Help, General Chat, Suggestions and Examples forums. If you can think of anything else that the forum needs then make a thread in the suggestions forum and I'll get round to it.

Hope you like it!

10. Advanced Interactivity


Today we're going to learn how to handle more advanced interactivity. We'll be making something like this:

Click on a face of the cube to zoom into it. Click it again to make the cube spin again.

So, in this tutorial I'm going to show you exactly how to work out which material has been clicked on the cube and act accordingly.

If you haven't read it already, I strongly suggest that you read the Basic Interactivity tutorial first or you'll probably miss something.

Ok, so on to the code.

Firstly we'll want six materials to apply to each face of the cube. Here are mine, although you can create whatever materials you like:

View as Plain Text (Copyable)
Actionscript:
  1.       private var frontMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/front.jpg");
  2.        private var backMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/back.jpg");
  3.        private var leftMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/left.jpg");
  4.        private var rightMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/right.jpg");
  5.        private var topMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/top.jpg");
  6.        private var bottomMaterial:BitmapFileMaterial = new BitmapFileMaterial("http://papervision2.com/wp-content/pvTex/bottom.jpg");

So, in this code I'm just loading six images from my server to use as each face.

Also, add the following declaration beneath the texture declarations to hold our Cube object:

View as Plain Text (Copyable)
Actionscript:
  1. private var cube:Cube;

Now we need to set up the 3d initiation code. In this code we will firstly set all of our materials as interactive, and then give each of our materials a name. This is VERY important to be able to easily find out which material has been clicked. If we didn't give each material a name then we wouldn't be able to easily work out which face has been clicked.

So, add the following code to your init3d() function:

View as Plain Text (Copyable)
Actionscript:
  1.       override protected function init3d():void {
  2.          // We need to be able to identify each side. We'll do this
  3.          // by asssigning names to each material. During this process
  4.          // we'll also make the materials interactive.
  5.          frontMaterial.interactive = true;
  6.          frontMaterial.name = "front";
  7.          backMaterial.interactive = true;
  8.          backMaterial.name = "back";
  9.          leftMaterial.interactive = true;
  10.          leftMaterial.name = "left";
  11.          rightMaterial.interactive = true;
  12.          rightMaterial.name = "right";
  13.          topMaterial.interactive = true;
  14.          topMaterial.name = "top";
  15.          bottomMaterial.interactive = true;
  16.          bottomMaterial.name = "bottom";
  17.          // ---------------------------------------------
  18.          
  19.          cube = new Cube(new MaterialsList( {
  20.               front: frontMaterial,
  21.               back: backMaterial,
  22.               left: leftMaterial,
  23.               right: rightMaterial,
  24.               top: topMaterial,
  25.               bottom: bottomMaterial
  26.               } ), 500, 500, 500, 3, 3, 3);
  27.          cube.addEventListener( InteractiveScene3DEvent.OBJECT_PRESS, onPress);
  28.          default_scene.addChild(cube);
  29.        }

So, In this code, we've set each material as interactive, given each one a sensible name, and initialised our cube with the materials assigned to the correct faces.

We then add an event listener to trigger the "onPress" event when the cube is clicked, then finally we add the cube to the scene.

We've now got a cube with six materials on it listening for a click event.

Now, the code which will let us work out which face has been clicked:

View as Plain Text (Copyable)
Actionscript:
  1. private function onPress( e:InteractiveScene3DEvent ):void {
  2.     switch(e.face3d.material.name) {
  3.        case "front":
  4.          // This code will be run when the front face is clicked
  5.        break;
  6.        case "back":
  7.          // This code will be run when the back face is clicked
  8.        break;
  9.        case "left":
  10.          // This code will be run when the left face is clicked
  11.        break;
  12.        case "right":
  13.          // This code will be run when the right face is clicked
  14.        break;
  15.        case "top":
  16.          // This code will be run when the top face is clicked
  17.        break;
  18.        case "bottom":
  19.          // This code will be run when the bottom face is clicked
  20.        break;
  21.     }
  22. }

Pretty self explanitary. The "e" variable in this code holds lots of data about the click event, including which material has been clicked, so, because we know which material is on each face, we can tell by the materials name which face has been clicked!

With a little bit of code, you can make a nice spinning cube gallery like the example above:

Here is my final code, have fun!
