Keyframe.inWeight

Description

Sets the incoming weight for this key. The incoming weight affects the slope of the curve from the previous key to this key.

The weight is a value between 0 and 1. Set weightedMode to WeightedMode.In or WeightedMode.Both to include weight when calculating the slope of the incoming curve.

See Also: outWeight.
