Upgrade the RNG of shake to Perlin Noise.

[stonetuskboar]

The current random number generator is the simple Unity.Mathematics.Random, which means the object's position changes every frame and fluctuates between negative and positive extremes. This behavior is not suitable for most object shaking scenarios, as the amplitude is too large and directly tied to the frame rate.

public readonly struct FloatShakeMotionAdapter : IMotionAdapter<float, ShakeOptions>
{
    public float Evaluate(ref float startValue, ref float endValue, ref ShakeOptions options, in MotionEvaluationContext context)
    {
        VibrationHelper.EvaluateStrength(endValue, options.Frequency, options.DampingRatio, context.Progress, out var s);
        //var multipliar = RandomHelper.NextFloat(options.RandomSeed, context.Time, -1f, 1f);
          var multipliar  =   Mathf.PerlinNoise(options.RandomSeed, (int)(context.Progress * frequency) * 0.2f); 
        // Perlin noise return same value when the input value is an integer, so it's necessary to change the RandomSeed to a float number.
        //The purpose of (int)(context.Progress * frequency) is to ensure speed steady during each shake frequency cycle.
        return startValue + s * multipliar;
    }
