Da Fish in Sea

Here’s my first stab at using the flash 10 player’s 3D capabilities. I wanted to get a sphere rotating around the y-axis, coming towards the viewer, then receding away. The way I did it was I gave the sphere a non-zero z-index, inside a container Sprite, which I then rotated around the y-axis (changing it’s y rotation). Once I saw it I realized I had made a mistake and that this approach wouldn’t work … but it’s a start so here it is anyway.

Note: It uses the Sphere class for the ‘planet’.

If you don’t see a revolving sphere above, then you need to install the flash player 10, which you can get here:

            orbit = new Sprite();

            //position orbit at center of stage

            orbit.x = 200;

            //add planet to orbit

            orbit.addChild(sphere);

            addChild(orbit);
