The documentation on animation on PPTX is really, really, lacking.
We're trying to animate a point from A to B, which must change colour depending on where it ends up.
Animating the motion path is ok :
EffectEx fxUserPath = pres.Slides.Timeline.MainSequence.AddEffect(circle, EffectTypeEx.PathUser, EffectSubtypeEx.None, EffectTriggerTypeEx.OnClick);
//Now extract the behaviour we just added
MotionEffectEx motionBhv = ((MotionEffectEx)fxUserPath.Behaviors);
PointF pts = new PointF;
motionBhv.Path.Add(MotionCommandPathTypeEx.LineTo, pts, MotionPathPointsTypeEx.Auto, true);
motionBhv.Path.Add(MotionCommandPathTypeEx.End, null, MotionPathPointsTypeEx.Auto, false);
The problem is then how to do the animation of color....
I'm GUESSING that I need to do something like this first :
EffectEx colourChange = pres.Slides.Timeline.MainSequence.AddEffect(circle, EffectTypeEx.ChangeFillColor, EffectSubtypeEx.None, EffectTriggerTypeEx.WithPrevious);
i.e. to say that I want to animate a "ChangeFillColor" and that it should happend "WithPrevious" i.e. at the same time as the move effect.
I GUESS that I should now extract something from "colourChange" which will let me determine what the fill colour should change to... something like EffectFillTypeEx, but I do not understand HOW.
Please enlighten us how better to use these (hopefully) powerful features you have build into Aspose.
