unity lerp

   float a=  Mathf.LerpAngle(-100,1000, 0.5f);
       Debug.Log("Mathf.LerpAngle : "+ a);
       a = Mathf.LerpUnclamped(-100, 1000, 1.5f);
       Debug.Log("Mathf.LerpUnclamped : " + a);
       a = Mathf.Lerp(-100, 1000, 1.5f);
       Debug.Log("Mathf.Lerp : " + a);

插值公式：

result = a+(b-a)*t

lerpAngle只要是计算过程中，值大于360 就会取余到360内

lerpUnclamped， 不做限制
