A mathematic curve.
    public class Curve : Resource

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.

Constructors

    public Curve()

Signals

    "range_changed" ()

Emitted when MaxValue or MinValue is changed.

Properties

    public Collections.Array _Data { get; set; }

    public int BakeResolution { get; set; }

The number of points to include in the baked (i.e. cached) curve data.

    public float MaxValue { get; set; }

The maximum value the curve can reach. Default value: 1.

    public float MinValue { get; set; }

The minimum value the curve can reach. Default value: 0.

Methods

    public int AddPoint(Vector2 position, float leftTangent = 0f, float rightTangent = 0f, TangentMode leftMode = TangentMode.Free, TangentMode rightMode = TangentMode.Free)

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.

    public void Bake()

Recomputes the baked cache of points for the curve.

    public void CleanDupes()

Removes points that are closer than CMP_EPSILON (0.00001) units to their neighbor on the curve.

    public void ClearPoints()

Removes all points from the curve.

    public int GetBakeResolution()

Getter for BakeResolution

    public float GetMaxValue()

Getter for MaxValue

    public float GetMinValue()

Getter for MinValue

    public int GetPointCount()

Returns the number of points describing the curve.

    public TangentMode GetPointLeftMode(int index)

Returns the left TangentMode for the point at index.

    public float GetPointLeftTangent(int index)

Returns the left tangent angle (in degrees) for the point at index.

    public Vector2 GetPointPosition(int index)

Returns the curve coordinates for the point at index.

    public TangentMode GetPointRightMode(int index)

Returns the right TangentMode for the point at index.

    public float GetPointRightTangent(int index)

Returns the right tangent angle (in degrees) for the point at index.

    public float Interpolate(float offset)

Returns the y value for the point that would exist at x-position offset along the curve.

    public float InterpolateBaked(float offset)

Returns the y value for the point that would exist at x-position offset along the curve using the baked cache. Bakes the curve’s points if not already baked.

    public void RemovePoint(int index)

Removes the point at index from the curve.

    public void SetBakeResolution(int resolution)

Setter for BakeResolution

    public void SetMaxValue(float max)

Setter for MaxValue

    public void SetMinValue(float min)

Setter for MinValue

    public void SetPointLeftMode(int index, TangentMode mode)

Sets the left TangentMode for the point at index to mode.

    public void SetPointLeftTangent(int index, float tangent)

Sets the left tangent angle for the point at index to tangent.

    public int SetPointOffset(int index, float offset)

Sets the offset from 0.5

    public void SetPointRightMode(int index, TangentMode mode)

Sets the right TangentMode for the point at index to mode.

    public void SetPointRightTangent(int index, float tangent)

Sets the right tangent angle for the point at index to tangent.

    public void SetPointValue(int index, float y)

Assigns the vertical position y to the point at index.

Inner Types

TangentMode

Name Value Description
Free 0 The tangent on this side of the point is user-defined.
Linear 1 The curve calculates the tangent on this side of the point as the slope halfway towards the adjacent point.
ModeCount 2 The total number of available tangent modes.
