第三章 创立游戏运行场景及角色管制

  1. 创立场景导入资源等
  2. 标签治理
    应用标签来进行断定，应用 const 缩小代码的出错率
    // 高空标签
    public const string ground = "Ground";//const 表明这个是一个共有的不可变的变量
    // 玩家标签
    public const string player = "Player";
  1. 鼠标管制人物挪动

鼠标点击高空特效，在角色上挂载脚本脚本

   public GameObject effect_click_prefab;   
    void Update()
    {
        // 检测鼠标的按下
        // 将鼠标的坐标转换为射线该
        // 射线与高空产生碰撞返回产生碰撞的点，而后让角色转向该点，开始挪动。当挪动到肯定范畴时进行挪动。if (Input.GetMouseButtonDown(0))
        {Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition);
            // 保留碰撞信息
            RaycastHit hitInfo;
            bool isCollider = Physics.Raycast(ray, out hitInfo);
            if(isCollider&& hitInfo.collider.tag   ==Tags.ground)
            {
                // 实例化点击的成果
                showClickEffect(hitInfo.point);
            }
        }
        void showClickEffect(Vector3 hitPoint)
        {hitPoint = new Vector3(hitPoint.x, hitPoint.y+0.1f,hitPoint.z);
            GameObject.Instantiate(effect_click_prefab, hitPoint, Quaternion.identity);
        }
    }

管制配角的朝向（鼠标点击高空的时候转向）
减少两个对象

private Vector3 targetPosition = Vector3.zero;
private bool isMoving = false;// 示意鼠标是否按下

在 update 办法的 if(isCollider&& hitInfo.collider.tag ==Tags.ground)中减少

 isMoving = true;
 LookAtTarget(hitInfo.point);

在 update 办法中减少两个断定语句

if (Input.GetMouseButtonUp(0))
        {isMoving = false;}
if (isMoving)
        {
            // 失去要挪动的指标地位
            // 让配角朝向指标地位
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitInfo;
            bool isCollider = Physics.Raycast(ray, out hitInfo);
            if (isCollider && hitInfo.collider.tag == Tags.ground)
            {LookAtTarget(hitInfo.point);
            }
        }

减少一个 lookat 办法

void LookAtTarget(Vector3 hitPoint)
    {
        targetPosition = hitPoint;
        targetPosition = new Vector3(targetPosition.x, transform.position.y, targetPosition.z);
        this.transform.LookAt(targetPosition);
    }

管制配角的挪动，添 PlayerMove 脚本挂载到角色上

默认值是以后地位不会在游戏一开始时就运行在 PlayDir 脚本 Start 函数中增加
targetPosition = transform.position；

public float speed = 4;  
private PlayerDir dir;
private CharacterController controller;
void Start()
    {dir = this.GetComponent<PlayerDir>();
        controller = this.GetComponent<CharacterController>();}
void Update()
    {float distance = Vector3.Distance(dir.targetPosition, transform.position);
        if (distance > 0.3f)
        {
            isMoving = true;
            //state = PlayerState.Moving;
            controller.SimpleMove(transform.forward * speed);
        }
    }

增加人物动画

管制人物动画播放的脚本

using UnityEngine;
using System.Collections;
public class PlayerAnimation : MonoBehaviour
{
    private PlayerMove move;
    void Start()
    {move = this.GetComponent<PlayerMove>();
    }
    void LateUpdate()
    {if (move.state == PlayerState.Moving)
        {PlayAnim("Run");
        }
        else if (move.state == PlayerState.Idle)
        {PlayAnim("Idle");
        }
    }
    void PlayAnim(string animName)
    {GetComponent<Animation>().CrossFade(animName);
    }
}

留神在 void PlayAnim 办法中教程中应用的旧版的代码，新版的代码为

GetComponent<Animation>().CrossFade(animName)；

欠缺的 PlayerDir 代码

public class PlayerDir : MonoBehaviour
{

    public GameObject effect_click_prefab;
    public Vector3 targetPosition = Vector3.zero;
    private PlayerMove playerMove;
    private bool isMoving = false;// 示意鼠标是否按下

    private void Start()
    {
        // 默认值是以后地位不会在游戏一开始时就运行
        targetPosition = transform.position;
        playerMove = this.GetComponent<PlayerMove>();}

    void Update()
    {if (Input.GetMouseButtonDown(0))
        {Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitInfo;
            bool isCollider = Physics.Raycast(ray, out hitInfo);
            if (isCollider && hitInfo.collider.tag == Tags.ground)
            {
                isMoving = true;
                ShowClickEffect(hitInfo.point);
                LookAtTarget(hitInfo.point);
            }
        }

        if (Input.GetMouseButtonUp(0))
        {isMoving = false;}

        if (isMoving)
        { 
            // 失去要挪动的指标地位
            // 让配角朝向指标地位
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitInfo;
            bool isCollider = Physics.Raycast(ray, out hitInfo);
            if (isCollider && hitInfo.collider.tag == Tags.ground)
            {LookAtTarget(hitInfo.point);
            }
        }
        else {if (playerMove.isMoving)
            {LookAtTarget(targetPosition);
            }
        }
    }
    // 实例化进去点击的成果
    void ShowClickEffect(Vector3 hitPoint)
    {hitPoint = new Vector3(hitPoint.x, hitPoint.y + 0.1f, hitPoint.z);
        GameObject.Instantiate(effect_click_prefab, hitPoint, Quaternion.identity);
    }
    // 让配角朝向指标地位
    void LookAtTarget(Vector3 hitPoint)
    {
        targetPosition = hitPoint;
        targetPosition = new Vector3(targetPosition.x, transform.position.y, targetPosition.z);
        this.transform.LookAt(targetPosition);
    }
}
  1. 管制相机追随配角的挪动
    在主摄像机挂在 FollowCamera 脚本
private Transform player;
    private Vector3 offsetPosition;// 地位偏移
    void Start()
    {player = GameObject.FindGameObjectWithTag(Tags.player).transform;
        // 使相机永远朝向配角
        transform.LookAt(player.position);
        offsetPosition = transform.position - player.position;
    }
    void Update()
    {transform.position = offsetPosition + player.position;}

应用鼠标滑动管制相机视线的拉近和拉远
定义一个 public float scrollSpeed = 10;
在下面的 Update 办法中减少 ScrollView()；办法

void ScrollView()
    {//print(Input.GetAxis("Mouse ScrollWheel"));// 向后 返回负值 (拉近视线) 向前滑动 返回正值(拉远视线)
        distance = offsetPosition.magnitude;
        // 获取鼠标中键的值
        distance += Input.GetAxis("Mouse ScrollWheel") *- scrollSpeed;
        distance = Mathf.Clamp(distance, 2, 18);
        offsetPosition = offsetPosition.normalized * distance;
    }

留神要在 distance += Input.GetAxis(“Mouse ScrollWheel”) *- scrollSpeed; 中的

  • scrollSpeed 负号，才是与实际效果统一

相机间隔的限度

  distance = Mathf.Clamp(distance, 2, 18);

相机的旋转

void RotateView()
    {//Input.GetAxis("Mouse X");// 失去鼠标在程度方向的滑动
        //Input.GetAxis("Mouse Y");// 失去鼠标在垂直方向的滑动
        if (Input.GetMouseButtonDown(1))
        {isRotating = true;}
        if (Input.GetMouseButtonUp(1))
        {isRotating = false;}

        if (isRotating)
        {transform.RotateAround(player.position, player.up, rotateSpeed * Input.GetAxis("Mouse X"));

            Vector3 originalPos = transform.position;
            Quaternion originalRotation = transform.rotation;

            transform.RotateAround(player.position, transform.right, -rotateSpeed * Input.GetAxis("Mouse Y"));// 影响的属性有两个 一个是 position 一个是 rotation
            float x = transform.eulerAngles.x;
            if (x < 10 || x > 80)
            {// 当超出范围之后，咱们将属性归位原来的，就是让旋转有效 
                transform.position = originalPos;
                transform.rotation = originalRotation;
            }

        }

        offsetPosition = transform.position - player.position;
    }

留神方向函数的符号，还有 update 办法中调用的程序

限定旋转的方向

 float x = transform.eulerAngles.x;
 if (x < 10 || x > 80)
            {// 当超出范围之后，咱们将属性归位原来的，就是让旋转有效 
                transform.position = originalPos;
                transform.rotation = originalRotation;
            }
  1. 减少角色状态信息
    给角色增加 playerstatus 脚本
    public int grade = 1;
    public int hp = 100;
    public int mp = 100;
    public int coin = 200;// 金币数量
    public int attack = 20;
    public int attack_plus = 0;
    public int def = 20;
    public int def_plus = 0;
    public int speed = 20;
    public int speed_plus = 0;
    public int point_remain = 0;// 残余的点数
