- .. _enum_Curve_TangentMode:
- .. _class_Curve_constant_TANGENT_FREE:
- .. _class_Curve_constant_TANGENT_LINEAR:
- .. _class_Curve_constant_TANGENT_MODE_COUNT:
- enum **TangentMode**:
- - **TANGENT_FREE** = **0** --- The tangent on this side of the point is user-defined.
- - **TANGENT_LINEAR** = **1** --- The curve calculates the tangent on this side of the point as the slope halfway towards the adjacent point.
- - **TANGENT_MODE_COUNT** = **2** --- The total number of available tangent modes.
- Description
- -----------
- A curve that can be saved and re-used for other objects. By default it ranges between ``0`` and ``1`` on the y-axis and positions points relative to the ``0.5`` y-position.
