Unity实现人物移动、旋转、跳跃-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity实现人物移动、旋转、跳跃。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。

1.Player脚本控制人物移动，可单独使用。（人物需添加组件Box Collider和Rigidbody）

using UnityEngine;
using UnityEngine.SceneManagement;
public class Player : MonoBehaviour
{

    Vector3 moveDirection;
    Rigidbody rb;
    float speed = 20.0f;
    float jumpHeight = 0;
    //初始化
    void Awake()
    {
        rb = GetComponent<Rigidbody>();
    }
    public void  setSpeed(float speeds)
    {
        speed = speeds;
    }
    
    void Update()
    {

        if (speed == 0) return;
        float steer = 20;
        float x = Input.GetAxis("Horizontal");
        transform.Rotate(0, x * steer * Time.deltaTime, 0);

        if (Input.GetKey(KeyCode.H))
        {
            speed = 50.0f;
        }
        else {
            speed = 20f;
        }
        
        float y = Input.GetAxis("Vertical");
        Vector3 s = y * transform.forward * speed * Time.deltaTime;
        transform.transform.position += s;   
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Jump(); 
        }

    }
    public void run() {

        //控制人物上下左右移动
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");
        float moveUp = Input.GetKey(KeyCode.Space) ? 1 : 0;
        Vector3 movement = new Vector3(moveHorizontal, moveUp, moveVertical);
        transform.Translate(movement * Time.deltaTime * speed);
    }
    //物理更新w
    void FixedUpdate()
    {
        if (speed == 0) return;
        rb.velocity = new Vector3(moveDirection.x, rb.velocity.y, moveDirection.z) + Vector3.up * jumpHeight;
        jumpHeight = 0f;//初始化跳跃高度
    }

    void Jump()
    {
        jumpHeight = 5f;
        
    }

}

2.相机放在人物头部，转动需要带着人物转，相机转动灵敏度和上下转动角度范围根据具体情况配置。

using UnityEngine;

public class CameraController : MonoBehaviour
{
    [Header("鼠标灵敏度")]
    public float mouseSensitivity = 4f;
    [Header("上下旋转最小角度")]
    public float minRotate = -60f;
    [Header("上下旋转最大角度")]
    public float maxRotate = 60f;

    //头部
    private Transform head;
    private float mouseX = 0f;
    private float mouseY = 0f;

    private void Awake()
    {
        //获取相机
        head = transform.Find("Main Camera");
    }

    // Start is called before the first frame update
    void Start()
    {

    }


    void Update()
    {
        //获取左右转动度数
        mouseX += Input.GetAxis("Mouse X") * mouseSensitivity;
        //获取上下转动度数
        mouseY += Input.GetAxis("Mouse Y") * mouseSensitivity;

        //上下转动限制范围
        mouseY = Mathf.Clamp(mouseY, minRotate, maxRotate);

        //控制相机和人物左右转动
        Quaternion quaternionX = Quaternion.AngleAxis(mouseX, Vector3.up);
        Quaternion quaternionY = Quaternion.AngleAxis(0, Vector3.left);
        transform.rotation = quaternionX * quaternionY;
        //控制相机上下转动
        quaternionY = Quaternion.AngleAxis(mouseY, Vector3.left);
        head.rotation = quaternionX * quaternionY;

        //人物移动
       Player player= GetComponent<Player>();
        player.run();

    }
}

脚本CameraController和Player直接挂载到人物就可以用了。
