Thanks Carl. I didn't understand that motion was a special add on. Even without using MotionBlur I still can't compile. It gives me the same error which is VerifyError: Error #1014: Class com.greensock.core::Animation could not be found. I must be missing something during the setup. I'm using Flash Builder 4.7, Air 17, Starling and trying to get greensock to work with that.... should it work? Also, just a side question when you call a greensock function your examples show MC (movieclip) as the object being sent into the method/function, can that be a Starling Image/Sprite or does this only work with a Flash MovieClip? I have done a few hours of searching the web for answers and not coming up with much that is helpful so that's why I'm using this forum. I usually don't use forums to get answers but I'm really struggling with this one and have been spinning my wheels trying to figure it out for about 5 hours. So, here's what I have imported: import com.greensock.*; import com.greensock.TweenMax; Here's the code I'm using and mybackround is a Starling Image TweenMax.to(mybackground, 3, {alpha:0.5}); When I compile I get this error: VerifyError: Error #1014: Class com.greensock.core::Animation could not be found If I comment out the TweenMax line the program compiles just fine.

I've included the greensock.SWC into my project. It knows its there because if I type com.gr.... it starts to fill in the data I included these to libraries: import com.greensock.* import com.greensock.easing.* Tried to run this command in the code: TweenLite.to(mybackground, .25, {x:0, y:0, motionBlur:true, ease:Cubic.easeInOut}); When I try to compile I get this error: VerifyError: Error #1014: Class com.greensock.core::Animation could not be found. If I comment out the TweenLite command the program will compile. Does anyone know what I'm doing wrong or what I'm suppose to import? I tried importing all of these and still the same result import com.greensock.TweenLite; import com.greensock.TweenMax; import com.greensock.*; import com.greensock.easing.*; import com.greensock.core.*; Do I have to run another command to start some animation library? Thanks for your help
