用键盘和鼠标控制物体移动的 Unity 3D 实现

using UnityEngine; using System.Collections; public class CameraMove : MonoBehaviour { //public设置三个灵敏度调节变量（方便更改灵敏度） public float sensitivityMouse = 2f; public float sensitivetyKeyBoard = 0.1f; public float sensitivetyMouseWheel = 10f; void Update() { //滚轮实现镜头缩进和拉远 //UnityEngine.Camera.main可以省略UnityEngine. //省略后脚本命名不能为Camera if (Input.GetAxis("Mouse ScrollWheel") != 0) { UnityEngine.Camera.main.fieldOfView = UnityEngine.Camera.main.fieldOfView-Input.GetAxis("Mouse ScrollWheel")* sensitivetyMouseWheel; } //按着鼠标右键实现视角转动 if (Input.GetMouseButton(1)) { transform.Rotate(-Input.GetAxis("Mouse Y") * sensitivityMouse, Input.GetAxis("Mouse X") * sensitivityMouse, 0); } //键盘按钮←/a和→/d实现视角水平移动，键盘按钮↑/w和↓/s实现视角水平旋转 if (Input.GetAxis("Horizontal") != 0) { transform.Translate(Input.GetAxis("Horizontal") * sensitivetyKeyBoard, 0, 0); } if (Input.GetAxis("Vertical") != 0) { transform.Translate(0, Input.GetAxis("Vertical") * sensitivetyKeyBoard, 0); } } }
