Properties

`Static`DegToRad

DegToRad: number

Constant mapping degrees to radians. This equals pi/180.

`Static`RadToDeg

RadToDeg: number

Constant mapping radians to degrees. This equals 180/pi.

Methods

`Static`clamp

clamp(v: number, lo: number, hi: number): number
Clamp floating-point value v in the range [lo, hi] (inclusive).
Parameters
- v: number
- lo: number
- hi: number
Returns number

`Static`lerp

lerp(a: number, b: number, time: number): number
Linearly interpolate from floating-point a to b, based on fraction t (where t=0.0 returns a, and t=1.0 returns b). This is equivalent to the vec2 and vec3 lerp() functions, but operates on scalar floating-point values.
Parameters
- a: number
- b: number
- time: number
Returns number

`Static`randomRange

randomRange(lo: number, hi: number): number
Generate a random floating-point value in the range [lo, hi). Note, the range is inclusive at the lower end, and exclusive at the upper.
Parameters
- lo: number
- hi: number
Returns number

`Static`remap

remap(
    v: number,
    inMin: number,
    inMax: number,
    outMin: number,
    outMax: number,
): number
Map floating-point v from range [inMin, inMax] to [outMin, outMax].
Parameters
- v: number
- inMin: number
- inMax: number
- outMin: number
- outMax: number
Returns number
