Class AnimationFunction<T>Abstract

Calculates the values between AnimationKeys. Represented internally by a cubic function (f(x) = ax³ + bx² + cx + d). Only needs to be recalculated when the keys change, so at runtime it should only be calculated once.

Abstract evaluate

  • evaluate(_time, _mutatorOut): T

  • Calculates the value of the function at the given time.

    Parameters

    • _time: number

      the point in time at which to evaluate the function in milliseconds. Will be corrected for offset internally.

    • _mutatorOut: AnimationReturnType

    Returns T

    the value at the given time

getParameters

  • getParameters(): {
        a: T;
        b: T;
        c: T;
        d: T;
    }

  • Returns the parameter values of this cubic function. f(x) = ax³ + bx² + cx + d Used by editor.

    Returns {
        a: T;
        b: T;
        c: T;
        d: T;
    }
