最后在缓和的情况下来回摇动一个物体？
我几乎想要一个刺耳的动画，这样它会快速地来回摇晃一秒钟，然后放慢速度，慢慢回到正常位置。 只有持续震动有很多答案，但我怎么能减少震动呢？ 我会Lerp真的很快，还是使用PingPong的function会变慢？
您只需通过获取原始位置然后在协程函数中简单地摇动YourObjTransform.position = defaultPos + UnityEngine.Random.insideUnitSphere * shakeAmount; ，执行YourObjTransform.position = defaultPos + UnityEngine.Random.insideUnitSphere * shakeAmount; 在一段时间内循环一段时间。 摇动GameObject后，将值重置回其默认位置。
至于减少震动，你做shakeAmount += Time.deltaTime; 在while循环中。 这将降低while循环中的摇动速度。
以下function是上述声明的完整示例。 它需要三个参数，GameObject可以摇动，动摇GameObject的时间以及开始减少震动的时间。
例如，如果你将myGameOBject ， 5f ， 3f传递给该函数，它将摇动myGameOBject ，总时间为5秒。 在摇动myGameOBject并且计数器达到3 ，它将开始降低摇动的速度（ shakeAmount ），直到计时器达到5 。
如果要抖动的SpriteRender是SpriteRender ，则将true传递给最后一个参数，以便z轴不会移动，并且在摇动时它只会在Z轴上旋转。
