- How To Use FIVe3D And Tweening in Flex
In a previous article I explained how to use FIVe3D with Flex and because fl.motion is not included into the Flex Framework we had to find out a workaround. I commented out the lines that referenced fl.motion but Kelvin Luck found another way: “copy the classes from Flash CS3 Actionscript framework into the project”. So this time the FIVe3D framework is untouched and fl.motion is included into the project.
Lets skip the intro and get into it… In this article I added some tweening to the example from the previous article. The framework I used are:
- TweenLite - http://blog.greensock.com/tweenliteas3/
- fl.transition - taken from Flash CS3 Actionscript 3 Framework
- Tweener - http://code.google.com/p/tweener/
These are the tree tweening frameworks we will add but from all of them TweenLite seems to be the easiest to use.
There is no visible difference between TweenLite, fl.transition and Tweener but in the future I may add some benchmarks.
Now take a look at the code and you can choose what tweenning library you’ll use.

Hi, just try a simple test: make your SWF with a low frame-rate and test it with the Tween frameworks above.
Do you know of any way to change the pivot(rotation) point or a Sprite3D object? Everything wants to rotate around a middle point.
I’m trying to add a number of objects to a scene and rotate them individually but on an edge axis. I’m hoping he’ll have documentation available soon, it’s been tough to find information on the class.
