Tweening custom attributes?

Are there any built in blocks to do this? I can't seem to find any other than the ones under motion.

Where are these blocks gone?

In Attributes tab

Those blocks don't exist anymore, although I don't know why.  The function is still listed in the API so you can probably try it out with code.

Code: [Select]

public function tweenNumber(attributeName:String, toValue:Number, duration:Number, easing:String):Boolean

cool, thanks for the help!
