Unity 脚本 | Unity相机控制脚本（鼠标键盘控制，简单实用） unity相机控制脚本，思路是仿照Unity Scene 里面控制的逻辑鼠标滚轮 上滚 拉近视野(放大)，下滚 推远视野(缩小)鼠标滚轮 按下并拖动，调整相机位置鼠标右键 按下并拖动，调整相机视角左键留空w a s d 类似于 fps 游戏一样前后左右移动ctrl 向下移动空格 向上移动该脚本直接挂载在相机上就可以用using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class MouseOperationCameraRotationFovMove : MonoBehaviour { public enum MouseState { None, MidMouseBtn, LeftMouseBtn } private MouseState mMouseState = MouseState.None; private Camera mCamera; private void Awake() { mCamera = GetComponent<Camera>(); if (mCamera==null) { UnityEngine.Debug.LogError(GetType()+"camera Get Error ……"); } GetDefaultFov(); } private void LateUpdate() { CameraRotate(); CameraFOV(); CameraMove(); } #region Camera Rotation //旋转最大角度 public int yRotationMinLimit = -90; public int yRotationMaxLimit = 0; //旋转速度 public float xRotationSpeed = 250.0f; public float yRotationSpeed = 120.0f; //旋转角度 private float xRotation = 0.0f; private float yRotation = 0.0f; /// <summary> /// 鼠标右间点下移动进行旋转 /// </summary> void CameraRotate() { if (Input.GetMouseButton(1)) // 0：鼠标左键；1：鼠标右键；2：鼠标中键 { if (mMouseState == MouseState.None) { // 保存当前的旋转角度,默认为0，0的时候代表第一次，获取一下 Vector3 currentRotation = transform.rotation.eulerAngles; if (xRotation == 0.0f && yRotation == 0.0f) { // 暂时不知道为啥X和Y要反过来 yRotation = -currentRotation.x; xRotation = 360 - currentRotation.y; } //Input.GetAxis("MouseX")获取鼠标移动的X轴的距离 xRotation -= Input.GetAxis("Mouse X") * xRotationSpeed * 0.02f; yRotation += Input.GetAxis("Mouse Y") * yRotationSpeed * 0.02f; yRotation = ClampValue(yRotation, yRotationMinLimit, yRotationMaxLimit);//这个函数在结尾 //欧拉角转化为四元数 Quaternion rotation = Quaternion.Euler(-yRotation, -xRotation, 0); transform.rotation = rotation; } } } #endregion #region Camera fov //fov 最大最小角度 public int fovMinLimit = 25; public int fovMaxLimit = 75; //fov 变化速度 public float fovSpeed = 50.0f; //fov 角度 private float fov = 0.0f; void GetDefaultFov() { fov = mCamera.fieldOfView; } /// <summary> /// 滚轮控制相机视角缩放 /// </summary> public void CameraFOV() { //获取鼠标滚轮的滑动量 fov -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * 100 * fovSpeed; // fov 限制修正 fov = ClampValue(fov,fovMinLimit, fovMaxLimit); //改变相机的 fov mCamera.fieldOfView = (fov); } #endregion #region Camera Move float _mouseX = 0; float _mouseY = 0; public float moveSpeed = 10; /// <summary> /// 中键控制拖动 /// </summary> public void CameraMove() { if (Input.GetMouseButton(2)) // 0：鼠标左键；1：鼠标右键；2：鼠标中键 { _mouseX = Input.GetAxis("Mouse X"); _mouseY = Input.GetAxis("Mouse Y"); //相机位置的偏移量（Vector3类型，实现原理是：向量的加法） Vector3 moveDir = (_mouseX * - transform.right + _mouseY * - transform.forward); //限制y轴的偏移量 moveDir.y = 0; transform.position += moveDir * 0.5f * moveSpeed; } else if (Input.GetMouseButtonDown(2)) { mMouseState = MouseState.MidMouseBtn; UnityEngine.Debug.Log(GetType() + "mMouseState = " + mMouseState.ToString()); } else if (Input.GetMouseButtonUp(2)) { mMouseState = MouseState.None; UnityEngine.Debug.Log(GetType() + "mMouseState = " + mMouseState.ToString()); } // WASD控制相机的前后左右移动 float horizontalInput = Input.GetAxis("Horizontal"); float verticalInput = Input.GetAxis("Vertical"); Vector3 direction = new Vector3(horizontalInput, 0, verticalInput).normalized; transform.Translate(direction * moveSpeed * Time.deltaTime); // Ctrl键控制相机向下移动 if (Input.GetKey(KeyCode.LeftControl) || Input.GetKey(KeyCode.RightControl)) { transform.Translate(Vector3.down * moveSpeed * Time.deltaTime); } // 空格键控制相机向上移动 if (Input.GetKey(KeyCode.Space)) { transform.Translate(Vector3.up * moveSpeed * Time.deltaTime); } } #endregion #region tools ClampValue //值范围值限定 float ClampValue(float value, float min, float max)//控制旋转的角度 { if (value < -360) value += 360; if (value > 360) value -= 360; return Mathf.Clamp(value, min, max);//限制value的值在min和max之间， 如果value小于min，返回min。 如果value大于max，返回max，否则返回value } #endregion } -
