2.导入素材  

3D GUNS | Guns Pack | 3D 武器 | Unity Asset Storehttps://assetstore.unity.com/packages/3d/props/weapons/3d-guns-guns-pack-228975

Prototyping Pack (Free) | 3D | Unity Asset Storehttps://assetstore.unity.com/packages/3d/prototyping-pack-free-94277 

3.搭建场景 

（1）选择合适的Meshes拖入场景中并调整位置 

  

（2）创建空物体“Environment”并将场景中的物体和Directional Light置于与其内部（使用Ctrl进行多选） 

（3）选择空物体“Environment”，调整Scale属性使其成比例放大

（4）  选择合适的Materials拖至对应物体

 效果图如下： 

4.创建玩家 

（1） 创建空物体“Player”并在其内部创建同为空物体“Graphis”和Camera，在“Graphis内部”创建一个球体作为玩家模型。Hierarchy中结构应如下：

对空物体“Player”添加Sphere Collider组件和Rigidbody组件 

Rigidbody组件的设置如下：  

 （2）选择合适的枪械素材，将其拖入场景并置于空物体“Player”中Camera下。Hierarchy中的物体结构应如下： 

分别先后将对应文件夹下的New Material和obstacle_texture拖至枪械素材 

适当调整枪械相对于玩家的位置

 （4）在Asset目录下创建Prefabs目录，并将刚刚创建的Player拖入所新创建的Prefabs目录以创建预制体

（5）在Asset目录下创建Scripts目录，用与放置所编写的各种script，并在其内部创建Player目录用于存储与Player相关的script

（6）在Player预制体上创建并编写PlayerInput.cs，用与接收玩家输入

using UnityEngine;

public class PlayerInput : MonoBehaviour
{
    [SerializeField]
    private float speed = 5f;
    [SerializeField] 
    private PlayerControllor playerControllor;
    [SerializeField] 
    private float lookSensitivity = 8f;
    
    // Start is called before the first frame update
    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
    }

    // Update is called once per frame
    void Update()
    {
        float xMov = Input.GetAxisRaw("Horizontal");
        float yMov = Input.GetAxisRaw("Vertical");

        Vector3 velocity = (transform.right * xMov + transform.forward * yMov).normalized*speed;
        playerControllor.Move(velocity);

        float xMouse = Input.GetAxisRaw("Mouse X");
        float yMouse = Input.GetAxisRaw("Mouse Y");

        Vector3 yRotation = new Vector3(0f, xMouse, 0f)*lookSensitivity;
        Vector3 xRotation = new Vector3(-yMouse, 0f, 0f)*lookSensitivity;
        playerControllor.Rotate(yRotation,xRotation);
    }
}

（7）在Player预制体是创建并编写PlayerController.cs，用于控制玩家行为

using UnityEngine;

public class PlayerControllor : MonoBehaviour
{
    [SerializeField] 
    private Rigidbody rb;
    [SerializeField] 
    private Camera _camera;
    
    private Vector3 velocity = Vector3.zero;//速度：每秒钟移动的距离
    private Vector3 yRotation=Vector3.zero;//旋转角色
    private Vector3 xRotation = Vector3.zero;//旋转视角
    
    public void Move(Vector3 _velocity)
    {
        velocity = _velocity;
    }

    public void Rotate(Vector3 _yRotation, Vector3 _xRotation)
    {
        yRotation = _yRotation;
        xRotation = _xRotation;
    }

    private void PerformMovement()
    {
        if (velocity != Vector3.zero)
        {
            rb.MovePosition(rb.position+velocity*Time.fixedDeltaTime);
        }
    }

    private void PerformRotation()
    {
        if (yRotation != Vector3.zero)
        {
            rb.transform.Rotate(yRotation);
        }
        if (xRotation != Vector3.zero)
        {
            _camera.transform.Rotate(xRotation);
        }
    }
    
    private void FixedUpdate()
    {
        PerformMovement();
        PerformRotation();
    }
}

将（6）（7）所编写的PlayerInput.cs和PlayerController.cs移动至Assets/Scripts/Player
