Unity3D学习_摄像机跟随脚本(及进阶版)_2018Oct
当目标点移动后,摄像机稍晚一步跟随移动,并在目标点停止时出现"平缓制动"效果.
脚本实现:
public float Speed; //跟随速度
public Transform TargetPos; //目标点信息
private Vector3 _distance; //距离
void Start()
{
_distance = transform.position - TargetPos.position;
Speed = 5;
}
void LateUpdate()
{
Vector3 newPos = TargetPos.position + _distance;
transform.position = Vector3.Lerp(transform.position, newPos, Speed * Time.deltaTime);
}
进阶版本:(实现了更多功能)
public class MouseFollow_ForRPG_CSharp : MonoBehaviour
{
public GameObject target;
public float ZoomSpeed = 30;//镜头缩放速率
public float MovingSpeed = 1;//镜头移动速率
public float RotateSpeed = 1; //镜头旋转速率
public float distance = 20;//设置距离角色的距离
public float ViewAngle = 30;//设置镜头斜视的角度
void Start()
{
if (target)
{
transform.rotation = Quaternion.Euler(ViewAngle, target.transform.rotation.eulerAngles.y, 0);
transform.position = transform.rotation * new Vector3(0, 0, -distance) + target.transform.position;
}
}
void Update()
{
Quaternion rotation;
Vector3 position;
float delta_x, delta_y;
float delta_rotation_x, delta_rotation_y;
if (target)
{
if (Input.GetMouseButton(0))
{
delta_x = Input.GetAxis("Mouse X") * MovingSpeed;
delta_y = Input.GetAxis("Mouse Y") * MovingSpeed;
rotation = Quaternion.Euler(0, transform.rotation.eulerAngles.y, 0);
transform.position = rotation * new Vector3(-delta_x, 0, -delta_y) + transform.position;
Debug.Log(-delta_x+" "+-delta_y);
}
else
{
if (Input.GetAxis("Mouse ScrollWheel") != 0)
{
distance += -Input.GetAxis("Mouse ScrollWheel") * ZoomSpeed;
}
if (Input.GetMouseButton(1))
{
delta_rotation_x = Input.GetAxis("Mouse X") * RotateSpeed;
delta_rotation_y = -Input.GetAxis("Mouse Y") * RotateSpeed;
transform.Rotate(0, delta_rotation_x, 0, Space.World);
transform.Rotate(delta_rotation_y, 0, 0);
}
else
{
transform.rotation = Quaternion.Slerp(transform.rotation,
Quaternion.Euler(transform.rotation.eulerAngles.x, target.transform.rotation.eulerAngles.y, 0
), Time.deltaTime * 2);
}
transform.position = transform.rotation * new Vector3(0, 0, -distance) + target.transform.position;
}
}
}
}
