- Signals
- -------
- .. _class_Curve_range_changed:
- - **range_changed** **(** **)**
- Emitted when :ref:`max_value<class_Curve_max_value>` or :ref:`min_value<class_Curve_min_value>` is changed.
- Member Variables
- ----------------
- .. _class_Curve_bake_resolution:
- - :ref:`int<class_int>` **bake_resolution** - The number of points to include in the baked (i.e. cached) curve data.
- .. _class_Curve_max_value:
- - :ref:`float<class_float>` **max_value** - The maximum value the curve can reach. Default value: ``1``.
- .. _class_Curve_min_value:
- - :ref:`float<class_float>` **min_value** - The minimum value the curve can reach. Default value: ``0``.
- Numeric Constants
- -----------------
- - **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.
- Member Function Description
- ---------------------------
- .. _class_Curve_add_point:
- - :ref:`int<class_int>` **add_point** **(** :ref:`Vector2<class_vector2>` position, :ref:`float<class_float>` left_tangent=0, :ref:`float<class_float>` right_tangent=0, :ref:`int<class_int>` left_mode=0, :ref:`int<class_int>` right_mode=0 **)**
- Adds a point to the curve. For each side, if the ``\*_mode`` is ``TANGENT_LINEAR``, the ``\*_tangent`` angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the ``\*_tangent`` angle if ``\*_mode`` is set to ``TANGENT_FREE``.
- .. _class_Curve_bake:
- - void **bake** **(** **)**
- Recomputes the baked cache of points for the curve.
