Instance Property

isAdditive

Determines if the value specified by the animation is added to the current render tree value to produce the new render tree value.

Declaration

var isAdditive: Bool { get set }

Discussion

If true, the value specified by the animation will be added to the current render tree value of the property to produce the new render tree value. The addition function is type-dependent, e.g. for affine transforms the two matrices are concatenated. The default is false.
