Flex for ActionScript 3.0 problem

[renton79]

Sorry for this stupid question but I have a little problem I have installed yesterday Flex Builder 3 trial and when working in AS project, I couldn't use such simple import as flash.geom.Matrix3D (Matrix is in there), dos Flex Builder 3 not have full as3 in it?

Matrix3D is a Flash Player 10 feature. Flex Builder 3 exports by default to FP 9. So you either use a workaround to publish your .swf files to FP 10 from Flex Builder ( or download the Flex 4 beta SDK and use that to export swf files to FP 10 ) or you download the trial of Flash Builder and use it instead.

You could also update the Flex SDK to version 3.3 if you don't want to use a beta product for whatever it is you're working on; it is also aware of the features in FP10. I think Flex Builder will do that automatically if you look in the menu for something like the 'Find Updates' button.
