public float inTangent;

Description

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

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