Unity 脚本实现相机自由移动
作者:互联网
建立一个脚本名称为:Move(与脚本内命名空间一致)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Move : MonoBehaviour
{
public Transform tourCamera;
#region 相机移动参数
public float moveSpeed = 1.0f;
public float rotateSpeed = 90.0f;
public float shiftRate = 2.0f;// 按住Shift加速
public float minDistance = 0.5f;// 相机离不可穿过的表面的最小距离(小于等于0时可穿透任何表面)
#endregion
#region 运动速度和其每个方向的速度分量
private Vector3 direction = Vector3.zero;
private Vector3 speedForward;
private Vector3 speedBack;
private Vector3 speedLeft;
private Vector3 speedRight;
private Vector3 speedUp;
private Vector3 speedDown;
#endregion
void Start()
{
if (tourCamera == null) tourCamera = gameObject.transform;
// 防止相机边缘穿透
//if (tourCamera.GetComponent<Camera>().nearClipPlane > minDistance / 3)
//{
// tourCamera.GetComponent<Camera>().nearClipPlane /= 3;
//}
}
void Update()
{
GetDirection();
// 检测是否离不可穿透表面过近
RaycastHit hit;
while (Physics.Raycast(tourCamera.position, direction, out hit, minDistance))
{
// 消去垂直于不可穿透表面的运动速度分量
float angel = Vector3.Angle(direction, hit.normal);
float magnitude = Vector3.Magnitude(direction) * Mathf.Cos(Mathf.Deg2Rad * (180 - angel));
direction += hit.normal * magnitude;
}
tourCamera.Translate(direction * moveSpeed * Time.deltaTime, Space.World);
}
private void GetDirection()
{
#region 加速移动
if (Input.GetKeyDown(KeyCode.LeftShift)) moveSpeed *= shiftRate;
if (Input.GetKeyUp(KeyCode.LeftShift)) moveSpeed /= shiftRate;
#endregion
#region 键盘移动
// 复位
speedForward = Vector3.zero;
speedBack = Vector3.zero;
speedLeft = Vector3.zero;

speedUp = Vector3.zero;
speedDown = Vector3.zero;
// 获取按键输入
if (Input.GetKey(KeyCode.W)) speedForward = tourCamera.forward;
if (Input.GetKey(KeyCode.S)) speedBack = -tourCamera.forward;
if (Input.GetKey(KeyCode.A)) speedLeft = -tourCamera.right;
if (Input.GetKey(KeyCode.D)) speedRight = tourCamera.right;
if (Input.GetKey(KeyCode.E)) speedUp = Vector3.up;
if (Input.GetKey(KeyCode.Q)) speedDown = Vector3.down;

#endregion
#region 鼠标旋转
if (Input.GetMouseButton(1))
{
// 转相机朝向
tourCamera.RotateAround(tourCamera.position, Vector3.up, Input.GetAxis("Mouse X") * rotateSpeed * Time.deltaTime);
tourCamera.RotateAround(tourCamera.position, tourCamera.right, -Input.GetAxis("Mouse Y") * rotateSpeed * Time.deltaTime);
// 转运动速度方向
direction = V3RotateAround(direction, Vector3.up, Input.GetAxis("Mouse X") * rotateSpeed * Time.deltaTime);
direction = V3RotateAround(direction, tourCamera.right, -Input.GetAxis("Mouse Y") * rotateSpeed * Time.deltaTime);
}
#endregion
}
public Vector3 V3RotateAround(Vector3 source, Vector3 axis, float angle)
{
Quaternion q = Quaternion.AngleAxis(angle, axis);// 旋转系数
return q * source;// 返回目标点
}
}
附加脚本到摄像机,搞定!
