Remarks
The following table summarizes how the SetBy, IXRDoubleAnimation::SetFrom, and IXRDoubleAnimation::SetTo methods can be used together or separately to determine the target values of an animation.
Method(s) used by the developer |
Resulting behavior |
|---|---|
SetFrom |
The animation progresses from the value specified in SetFrom to the base value of an animated property, or to the output value of a previous animation, depending on how the previous animation is configured. |
SetFrom and SetTo |
The animation progresses from the value specified in SetFrom to the value specified in SetTo. |
SetFrom and SetBy |
The animation progresses from the value specified in SetFrom to the sum of the values specified in SetFrom and SetBy. |
SetTo |
The animation progresses from the base value of the animated property or from the output value of a previous animation to the value specified in SetTo. |
SetBy |
The animation progresses from the base value of the animated property or the output value of a previous animation to the sum of that value and the value specified in SetBy. |
If you use both the SetTo and SetBy methods, the value specified in SetTo takes precedence and the SetBy property is ignored.
