Syntax

virtual HRESULT STDMETHODCALLTYPE SetBy(

Remarks

The following table summarizes how the SetBy, IXRDoubleAnimation::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.
