Class BezierCurve<T>

An animation spline represented by a set of keyframes, each representing an endpoint of a Bezier curve.

System.Object
CurveBase<T>
BezierCurve<T>
Namespace: FlaxEngine
Assembly: FlaxEngine.CSharp.dll
Syntax
public class BezierCurve<T> : CurveBase<T> where T : new()
Type Parameters
T

The animated value type.

Constructors

BezierCurve()

Initializes a new instance of the BezierCurve<T> class.

Declaration
public BezierCurve()

BezierCurve(BezierCurve<T>.Keyframe[])

Initializes a new instance of the BezierCurve<T> class.

Declaration
public BezierCurve(params BezierCurve<T>.Keyframe[] keyframes)
Parameters
BezierCurve.Keyframe<>[] keyframes

The keyframes.

BezierCurve(IEnumerable<BezierCurve<T>.Keyframe>)

Initializes a new instance of the BezierCurve<T> class.

Declaration
public BezierCurve(IEnumerable<BezierCurve<T>.Keyframe> keyframes)
Parameters
System.Collections.Generic.IEnumerable<BezierCurve.Keyframe<>> keyframes

The keyframes.

Fields

Keyframes

The keyframes collection. Can be directly modified but ensure to sort it after editing so keyframes are organized by ascending time value.

Declaration
[Serialize]
public BezierCurve<T>.Keyframe[] Keyframes
Field Value
BezierCurve.Keyframe<>[]

Methods

Evaluate(out T, Single, Boolean)

Evaluates the animation curve value at the specified time.

Declaration
public override void Evaluate(out T result, float time, bool loop = true)
Parameters
T result

The interpolated value from the curve at provided time.
System.Single time

The time to evaluate the curve at.
System.Boolean loop

If true the curve will loop when it goes past the end or beginning. Otherwise the curve value will be clamped.
Overrides
FlaxEngine.CurveBase<T>.Evaluate(T, System.Single, System.Boolean)

EvaluateKey(out BezierCurve<T>.Keyframe, Single, Boolean)

Evaluates the animation curve key at the specified time.

Declaration
public void EvaluateKey(out BezierCurve<T>.Keyframe result, float time, bool loop = true)
Parameters
BezierCurve.Keyframe<> result

The interpolated key from the curve at provided time.
System.Single time

The time to evaluate the curve at.
System.Boolean loop

If true the curve will loop when it goes past the end or beginning. Otherwise the curve value will be clamped.

FindKeys(Single, out Int32, out Int32)

Returns a pair of keys that can be used for interpolating to field the value at the provided time.

Declaration
public override void FindKeys(float time, out int leftKey, out int rightKey)
Parameters
System.Single time

The time for which to find the relevant keys from. It is expected to be clamped to a valid range within the curve.
System.Int32 leftKey

The index of the key to interpolate from.
System.Int32 rightKey

The index of the key to interpolate to.
Overrides
FlaxEngine.CurveBase<T>.FindKeys(System.Single, System.Int32, System.Int32)

TransformTime(Single, Single)

Applies the linear transformation (scale and offset) to the keyframes time values.

Declaration
public override void TransformTime(float timeScale, float timeOffset)
Parameters
System.Single timeScale

The time scale.
System.Single timeOffset

The time offset.
Overrides
FlaxEngine.CurveBase<T>.TransformTime(System.Single, System.Single)

Trim(Single, Single)

Trims the curve keyframes to the specified time range.

Declaration
public override void Trim(float start, float end)
Parameters
System.Single start

The time start.
System.Single end

The time end.
Overrides
FlaxEngine.CurveBase<T>.Trim(System.Single, System.Single)
