Precisely, we are usually doing it using the movieClip it self, but that doesn't work in this case, because MovieClipSpriteProjector overwrites the movieClip scaleX and scaleY to handle distance with the camera. So, as I said in my first e-mail, our work-around was to wrap the movie clip inside another movieClip that I'd use as a texture for the movieClipSprite, but it didn't sound perfectly right to me, which is why I figured that since there already was a "scaling" property in the movieClipSprite I'd just need to extend that into xScaling and yScaling to get what I was after. And that's about it.
Clearly this feature is not an absolute must have, since you can work-around it by wrapping two movieClips inside each other. I just figured it made sense since the MovieClipSprite already had a "scaling" attribute. And don't worry about killing my spirit, I'm much more resilient than that. :) Hope this clarifies what I was after however, and thanks and congrats again on the great work on the engine. -- Axelle On Thu, Jan 14, 2010 at 1:10 PM, Fabrice3D <[email protected]> wrote: > k, I can figure out the "sprite" flipping idea and imagine the resulting 2d > use you are after. > Yet I still not see why not just affect the source mc itself? > I mean, that if the handling of angle movieclipsprite/cam was automatically > handled by the class then the class should handle the distorsion as well. > But here its not the case. > > Just keep in mind that I'm not trying to kill your spirit here! :) > we love when we get patches or inputs, but in this case, I'm just not > convinced it would be a usefull addition > considering the fact that you can do this very easyly without changing a > single line. > > feel free shoot at me, if I'm wrong or miss something! :) > > Fabrice > > > On Jan 14, 2010, at 12:33 PM, Axelle Ziegler wrote: > >> Well that's actually 2D, and not 3D, behaviour.
