Constructors

constructor

new CurveSet(...args: any[]): CurveSet
Creates a new CurveSet instance.
Parameters
- ...args: any[]
  Variable arguments with several possible formats:
  
  No arguments: Creates a CurveSet with a single default curve.
  
  Single number argument: Creates a CurveSet with the specified number of default curves.
  
  Single array argument: An array of arrays, where each sub-array contains keys (pairs of numbers with the time first and value second).
  
  Multiple arguments: Each argument becomes a separate curve.
Returns CurveSet
Example
```
// Create from an array of arrays of keys
const curveSet = new pc.CurveSet([
    [
        0, 0,        // At 0 time, value of 0
        0.33, 2,     // At 0.33 time, value of 2
        0.66, 2.6,   // At 0.66 time, value of 2.6
        1, 3         // At 1 time, value of 3
    ],
    [
        0, 34,
        0.33, 35,
        0.66, 36,
        1, 37
    ]
]);

Accessors

length

get length(): number
Gets the number of curves in the curve set.

Returns number
- Defined in core/math/curve-set.js:76

type

get type(): number
Gets the interpolation scheme applied to all curves in the curve set.

Returns number
- Defined in core/math/curve-set.js:104
set type(value: number): void
Sets the interpolation scheme applied to all curves in the curve set. Can be:
Defaults to CURVE_SMOOTHSTEP.
Parameters
- value: number
Returns void
- Defined in core/math/curve-set.js:92

Methods

clone

clone(): CurveSet
Returns a clone of the specified curve set object.

Returns CurveSet
A clone of the specified curve set.
- Defined in core/math/curve-set.js:143

get

get(index: number): Curve
Return a specific curve in the curve set.
Parameters
- index: number
  The index of the curve to return.
Returns Curve
The curve at the specified index.
- Defined in core/math/curve-set.js:114

value

value(time: number, result?: number[]): number[]
Returns the interpolated value of all curves in the curve set at the specified time.
Parameters
- time: number
  The time at which to calculate the value.
- Optionalresult: number[] = []
  The interpolated curve values at the specified time. If this parameter is not supplied, the function allocates a new array internally to return the result.
Returns number[]
The interpolated curve values at the specified time.
