HODGEDEV FLASH BLOG

I have a client that needs some simple 3D. Since I am allowed to develop the project for Flash Player 10, and my 3D needs were simplistic, I chose not to use Papervision3D. I began things like normal. I opened FlashDevelop3 and created a project. Then, I opened Flash CS4 and created a rectangle. With a mock-up of the final product in the background, I began to rotate the rectangle in 3D space; until it matched the comp. When I was happy, I tested the movie, and sure enough everything looked great.

After getting my creative into its proper position and perspective, I moved on to link the DocumentClass that FlashDevelop3 created when I created my project, to the newly created flash file. As soon as I entered the document class, I tested the movie. My rectangle no longer had perspective and was only barely visible on screen. I removed the document class and all the sudden my rotation values were back.

I began to scour google for answers and eventually found some on adobe’s site. What what said on adobe’s site was to set the following in your class.

//”this” applies to my DocumentClass
this.transform.perspectiveProjection.projectionCenter = new Point(someNumber,someNumber);
this.transform.perspectiveProjection.fieldOfView = someInt;

Having this information, I quickly entered in and tested my movie. I was a bit saddened to see that nothing had changed. I sat for a moment and thought about it. If the values for projectionCenter and fieldOfView must be set if using a document class, then it is possible that any rotation on the X, Y, or Z, in the Flash IDE may have been ignored. I quickly set rotation values with actionscript and tested the movie. EUREKA! It works.

Hopefully this little tid-bit of information can save you from the aggravation I went through
