unity通过脚本实现漫游功能 wasd控制玩家移动，空格跳跃，鼠标控制视野旋转，滑轮控制镜头伸缩

这篇具有很好参考价值的文章主要介绍了unity通过脚本实现漫游功能 wasd控制玩家移动，空格跳跃，鼠标控制视野旋转，滑轮控制镜头伸缩。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

将场景中的摄像机删除，在玩家的控制面板中添加Camera组件，和rigibody组件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class move : MonoBehaviour
{
public float speed;
Rigidbody rigid;
void Start()
{

rigid = GetComponent<Rigidbody>();
}
void Update()
{
moveAction();
}
private void moveAction()
{
float h = Input.GetAxis("Horizontal");
float v = Input.GetAxis("Vertical");
transform.Translate(h * speed * Time.deltaTime, 0, v * speed * Time.deltaTime);
rigid.constraints = RigidbodyConstraints.FreezeRotation;
if ((Input.GetKeyDown(KeyCode.Space)) && (rigid.velocity.y == 0))
{
rigid.AddForce(new Vector3(0, 150, 0));
}
float qx = Input.GetAxis("Mouse X");
float qy = -Input.GetAxis("Mouse Y");
Quaternion xoff = Quaternion.Euler(0, qx, 0);
Quaternion yoff = Quaternion.Euler(qy, 0, 0);
if (Input.GetAxis("Mouse ScrollWheel") > 0)
{
GetComponent<Camera>().fieldOfView--;
}

if (Input.GetAxis("Mouse ScrollWheel") < 0)
{
GetComponent<Camera>().fieldOfView++;
}

transform.rotation = xoff * transform.rotation;
transform.rotation = transform.rotation * yoff;
float angle = transform.eulerAngles.x;
if (angle > 180)
angle -= 360;
if (angle < -180)
angle += 360;
if (angle > 15)
transform.rotation = Quaternion.Euler(15, transform.eulerAngles.y, 0);
if (angle < -15)
transform.rotation = Quaternion.Euler(-15, transform.eulerAngles.y, 0);
}
