Hi Status,

I understand that you applied a group of Transform on animation target. The problem you encountered is TranslateTransform isn't precise, it cannot translate target to correct place. If I misunderstood you, please correct me.

From your description, I assume that you used ScaleTransform. When using ScaleTransform, the actual translate distance is

[actual distance] = [translate property value] * [scale ratio]

This may be the reason why animation target doesn't move enough distance as TranslateTransform's property set. Could you confirm this?

For more information about Transform, please check this article

Thanks,

Here i have a full example with source talk about how to dymtic set up the endpoint for animation!

I've been doing something similar. Not sure what a DoubleAnimationKeFrame is though. My transform animation is a DoubleAnimationUsingKeyFrames with SplineDoubleKeyFrames within it. The ending value is correct, but it's not animating to the correct spot, it's 1/2 the value it should be.

</Storyboard>

Code:

DoubleAnimationUsingKeyFrames daukf2 = (DoubleAnimationUsingKeyFrames)animateUp.Children[3];
                    daukf2.KeyFrames[0].Value = startingYloc; // starting point
                    daukf2.KeyFrames[1].Value = halfY; // halfway point
                    daukf2.KeyFrames[2].Value = modYloc; // Ending point

You can access DoubleAnimationKeyFrame for starting frame and the same for the ending frame.

You can get the DoubleAnimationKeyFrame for end frame as

DoubleAnimationKeyFrame endKeyFrameInstance=StoryboardObject.Children[StoryboardObject.Children.Count-1];

set end value as

endKeyFrameInstance.EndValue=someValue;

Animation Question - Changing Endpoint Programatically

Status — Mon, 29 Jun 2009 15:37:06 GMT

I have a question about changing an endpoint for an existing animation programatically. I have a circle that does some animation (skew, resizing...etc) from it's current position to X,Y in a set amount of time. Is there an easy way to set the destination X,Y?

I have been playing with using a DoubleAnimationUsingKeyFrames on the animation, but my end point never ends in the correct place (the end keyFrame, always the next to last key frame).
