• [Unity] 制作游戏 赛车小游戏

    模拟赛车小游戏

    效果展示

    请添加图片描述
    做一款模拟赛车的小游戏demo，方向键控制、有刹车、重玩，还有漂移和查看车型的功能
    可以看到，还有翻车的效果哈哈哈！有兴趣的小伙伴来看看吧！

    资源准备

    1. 从网上下载赛车模型和桥梁路的模型
    2. 项目下载链接在文章末尾

    赛车模型如下：请添加图片描述
    然后将桥和路摆放入游戏场景
    请添加图片描述
    再把车放入适当的位置，加入刚体（将刚体mess调节到1000）和车轮碰撞器，层级结构如下：
    请添加图片描述
    车轮碰撞器如下操作，在车内部中新建空节点，然后再建四个空节点，给每个这四个空节点都加上Wheel Collider车轮碰撞器，然后将这四个车轮节点的位置逐个摆放到车子车轮对应的位置，最后稍微调节一下车轮的Friction参数即可。
    在这里插入图片描述

    最后再添加几个button在ui上，层级如下:
    请添加图片描述
    请添加图片描述

    代码阶段

    然后将车挂上脚本lanBoCar.cs
    首先写入要在编辑器中配置的所有public变量

    using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class lanBoCar : MonoBehaviour
{
    public float angleSpeed;
    public float moveSpeed;
    public WheelCollider[] wheels;
    public Transform[] modelTrs;
    public Button[] contrKeyPad;
    public GameObject camera;
    public Button reset;
    public GameObject objbody;
    public GameObject cam;
    public Button LOOK;
    ...

    请添加图片描述
    然后写相机镜头锁定车的脚本
    camera.cs

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

public class camera : MonoBehaviour
{
    public GameObject pos;
    private Vector3 offset;
    public GameObject playerCar;
    public GameObject ca;

    private int lookid = 0;

    public int canRot = 1;
    void Start()
    {
        offset = transform.position - playerCar.transform.position;

        transform.position = ca.transform.position;
        transform.localEulerAngles = ca.transform.localEulerAngles;
    }

    void Update()
    {
        if (lookid == 1)
        {   
            Vector3 pPos = playerCar.transform.position;
            pPos.z -= 4f;
            pPos.y += 1.5f;
            transform.position = pPos;
            transform.localEulerAngles = ca.transform.localEulerAngles;
        }
        else
        {
            transform.position = ca.transform.position;
            float y = playerCar.transform.localEulerAngles.y;
            float z = playerCar.transform.localEulerAngles.z;
            if (canRot == 0)
            {
                transform.localEulerAngles = new Vector3(transform.localEulerAngles.x, y, z);
            }
            else
            {
                transform.localEulerAngles = new Vector3(transform.localEulerAngles.x, y + (Time.deltaTime * 10), z);
            }
        }
    }

    void changeRot(string v)
    {
        if (v == "stop")
        {
            canRot = 0;
        }
        if (v == "begin")
        {
            canRot = 1;
        }
    }

    void look(int ids)
    {
        lookid = ids;
    }

}

    再写上操作方向键的上下左右button的脚本
    button.cs

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

public class button : MonoBehaviour,IPointerDownHandler,IPointerUpHandler
{   
    public float[] vh;
    public GameObject car;

    public void OnPointerDown(PointerEventData ed)
    {
        string chec = "";

        if (vh.Length == 1 && vh[0] == 2)
        {   
            int idx = 1;
            car.SendMessage("checkTail", idx);
            return;
        }
        if (vh[0] == 1)
        {
            chec = "up";
        }
        if(vh[0] == -1){
            chec = "down";
        }
        if (vh[1] == -1)
        {
            chec = "left";
        }
        if (vh[1] == 1)
        {
            chec = "right";
        }
        car.SendMessage("checkEvent", chec);
    }

    public void OnPointerUp(PointerEventData ed)
    {
        string chec = "";

        if (vh.Length == 1 && vh[0] == 2)
        {
            int idx = 0;
            car.SendMessage("checkTail", idx);
            return;
        }
        if (vh[0] == 1)
        {
            chec = "uSTOP";
        }
        if (vh[0] == -1)
        {
            chec = "dSTOP";
        }
        if (vh[1] == -1)
        {
            chec = "lSTOP";
        }
        if (vh[1] == 1)
        {
            chec = "rSTOP";
        }
        car.SendMessage("checkEvent", chec);

    然后把这个button.cs挂到每个方向键的组件上

    最后写入车的脚本
    lanBoCar.cs
