A mathematic curve. A curve that can be saved and re-used for other objects. By default it ranges between [code]0[/code] and [code]1[/code] on the y-axis and positions points relative to the [code]0.5[/code] y-position. Adds a point to the curve. For each side, if the [code]*_mode[/code] is [constant TANGENT_LINEAR], the [code]*_tangent[/code] angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the [code]*_tangent[/code] angle if [code]*_mode[/code] is set to [constant TANGENT_FREE]. Recomputes the baked cache of points for the curve. Removes points that are closer than [code]CMP_EPSILON[/code] (0.00001) units to their neighbor on the curve. Removes all points from the curve. Returns the number of points describing the curve. Returns the left [code]TangentMode[/code] for the point at [code]index[/code]. Returns the left tangent angle (in degrees) for the point at [code]index[/code]. Returns the curve coordinates for the point at [code]index[/code]. Returns the right [code]TangentMode[/code] for the point at [code]index[/code]. Returns the right tangent angle (in degrees) for the point at [code]index[/code]. Returns the y value for the point that would exist at x-position [code]offset[/code] along the curve. Returns the y value for the point that would exist at x-position [code]offset[/code] along the curve using the baked cache. Bakes the curve's points if not already baked. Removes the point at [code]index[/code] from the curve. Sets the left [code]TangentMode[/code] for the point at [code]index[/code] to [code]mode[/code]. Sets the left tangent angle for the point at [code]index[/code] to [code]tangent[/code]. Sets the offset from [code]0.5[/code] Sets the right [code]TangentMode[/code] for the point at [code]index[/code] to [code]mode[/code]. Sets the right tangent angle for the point at [code]index[/code] to [code]tangent[/code]. Assigns the vertical position [code]y[/code] to the point at [code]index[/code]. The number of points to include in the baked (i.e. cached) curve data. The maximum value the curve can reach. Default value: [code]1[/code]. The minimum value the curve can reach. Default value: [code]0[/code]. Emitted when [member max_value] or [member min_value] is changed. The tangent on this side of the point is user-defined. The curve calculates the tangent on this side of the point as the slope halfway towards the adjacent point. The total number of available tangent modes.
