Unity3D中抖屏（抖动相机）效果的简单实现

public class CameraShake : MonoBehaviour {

// 抖动目标的transform(若未添加引用，怎默认为当前物体的transform)
public Transform camTransform;

//持续抖动的时长
public float shake = 0f;

// 抖动幅度（振幅）
　　//振幅越大抖动越厉害
public float shakeAmount = 0.7f;
public float decreaseFactor = 1.0f;

Vector3 originalPos;

void Awake()
{
if (camTransform == null)
{
camTransform = GetComponent(typeof(Transform)) as Transform;
}
}

void OnEnable()
{
originalPos = camTransform.localPosition;
}

void Update()
{
if (shake > 0)
{
camTransform.localPosition = originalPos + Random.insideUnitSphere * shakeAmount;

shake -= Time.deltaTime * decreaseFactor;
}
else
{
shake = 0f;
camTransform.localPosition = originalPos;
}
}
}
