Remarks
The following table summarizes how the IXRDoubleAnimation::SetBy, SetFrom, and IXRDoubleAnimation::SetTo methods can be used together or separately to determine an animation's target values.
| Method(s) used by the developer | Resulting behavior |
|---|---|
SetFrom |
The animation progresses from the value specified in SetFrom to the animated property's base value or to a previous animation's output value, 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 animated property's base value or from a previous animation's output value to the value specified in SetTo. |
SetBy |
The animation progresses from the animated property's base value or a previous animation's output value 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.
