Keyframe.outTangent

설명

Sets the outgoing tangent for this key. The outgoing tangent affects the slope of the curve from this key to the next key.

The outgoing tangent matches the outgoing slope of the curve. A positive value for inTangent results in an upward tangent, while a negative value results in a downward tangent.
