Unity: 打飞碟简单版
游戏规则
- 一共有三个回合，随着回合增加，单位时间出现的飞碟数合飞碟的速度都会增加
- 分数由玩家点击的飞碟颜色决定，黑色3分，红色2分，黄色1分
- 每个回合有20个飞碟
- 没有失败的条件，最后看分数多少

在老师给的框架下做一些扩展即可

Disk.cs 飞碟的属性脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

//方向
public Vector3 Direction {
get {

DiskFactory.cs 飞碟工厂，管理飞碟的产生、销毁
using System.Collections;

CCFlyAction.cs 具体的飞行动作
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//飞行的动作，由上个游戏的CCMoveToAction改动过来的
public class CCFlyAction : SSAction
{
//速度分解为x和y方向，y方向初始为0
public float speedx;
public float speedy = 0;
private CCFlyAction() {
}
//单例模式，给定初始的x方向速度
public static CCFlyAction getAction(float speedx)
{
CCFlyAction action = CreateInstance<CCFlyAction>();
action.speedx = speedx;
return action;
}
//运动
public override void Update()
{
// dx = vt
float deltax = speedx * Time.deltaTime;
// dy = yt + 0.5at^2
float deltay = -speedy * Time.deltaTime + (float)-0.5 * 10 * Time.deltaTime * Time.deltaTime;
this.transform.position += new Vector3(deltax, deltay,0);
// y' = y + at
speedy += 10*Time.deltaTime;
//当飞碟的位置的y坐标小于阈值，认为消失在用户视野中，执行销毁
if (transform.position.y <= 1)
{
destroy = true;
CallBack.SSActionCallback(this);
}
}
public override void Start()
{
}
}
Interfaces.cs：接口定义，主要修改UserAction接口
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace Interfaces
{
public interface ISceneController
{
void LoadResources();
}
public interface UserAction
{
void Hit(Vector3 pos); //鼠标点击
void Restart(); //开始和重新开始都一样
int GetScore();
bool RoundStop(); //最后的回合结束
int GetRound();
}
public enum SSActionEventType : int {
Started, Completed }
public interface SSActionCallback
{
void SSActionCallback(SSAction source);
}
}
FirstSceneController.cs：挂在空项目上的脚本，场景控制器
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Interfaces;
public class FirstSceneController : MonoBehaviour, ISceneController, UserAction
{
int score = 0; //分数
int round = 1; //回合，设置了3个
int producedDiskNum = 0; //每回合已经产生的飞碟数目
bool start = false;
CCActionManager Manager;
DiskFactory DF;
void Awake()
{
SSDirector director = SSDirector.getInstance();
director.currentScenceController = this;
DF = DiskFactory.DF;
Manager = GetComponent<CCActionManager>();
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
int count = 0;
void Update () {
//val帧产生一个飞碟
int val;
switch (round)
{
case 1:
val = Random.Range(60, 80);
break;
case 2:
val = Random.Range(45, 60);
break;
default:
val = 40;
break;
}
if(start)
{
count++;
if (count >= val) //val帧一个飞碟
{
count = 0;
if(DF == null)
{
Debug.LogWarning("DF is NUll!");
return;
}
producedDiskNum++;
Disk d = DF.GetDisk(round);
Manager.MoveDisk(d);
if (producedDiskNum == 15) //15个飞碟进入下一个回合
{
round++;
producedDiskNum = 0;
}
}
}
}
public void LoadResources()
{
}
public void Hit(Vector3 pos)
{
Ray ray = Camera.main.ScreenPointToRay(pos);
RaycastHit[] hits;
hits = Physics.RaycastAll(ray);
for (int i = 0; i < hits.Length; i++)
{
RaycastHit hit = hits[i];
//根据颜色加分
if (hit.collider.gameObject.GetComponent<Disk>() != null)
{
Color c = hit.collider.gameObject.GetComponent<Renderer>().material.color;
if (c == Color.yellow) score += 1;
if (c == Color.red) score += 2;
if (c == Color.black) score += 3;
hit.collider.gameObject.transform.position = new Vector3(0, -5, 0);
}
}
}
public int GetScore()
{
return score;
}
//初始化各变量
public void Restart()
{
score = 0;
round = 1;
start = true;
}
//到了第三回合要判断是否结束
public bool RoundStop()
{
if (round > 3)
{
start = false;
return Manager.IsAllFinished();//是否还有飞碟留在used列表里
}
else return false;
}
public int GetRound()
{
return round;
}
}
InterfaceGUI.cs：挂在相机的脚本，负责管理与玩家的界面管理
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Interfaces;
using UnityEngine.UI;
//挂在相机的脚本
public class InterfaceGUI : MonoBehaviour {
UserAction userAction;
bool isPlaying = false;
float S;
int round = 1;
// Use this for initialization
void Start () {
userAction = SSDirector.getInstance().currentScenceController as UserAction;
S = Time.time;
}
private void OnGUI()
{
if(!isPlaying) S = Time.time;
//分数、时间、回合
string text = "分数: " + userAction.GetScore().ToString() + " 时间: " + ((int)(Time.time - S)).ToString() + " 回合: " + round;
GUI.Label(new Rect(10, 10, Screen.width, 50),text);
if (!isPlaying && GUI.Button(new Rect(Screen.width / 2 - 75, Screen.height / 2 - 25, 150, 50), "开始游戏"))
{
S = Time.time;
isPlaying = true;
userAction.Restart(); //点击开始游戏，FirstSceneController开始游戏
}
if (isPlaying)
{
round = userAction.GetRound();
if (Input.GetButtonDown("Fire1"))
{
//把鼠标点击的位置传给FirstScenceController，处理点击事件
Vector3 pos = Input.mousePosition;
userAction.Hit(pos);
}
if (round > 3) //round>3要等待飞碟都用完了
{
round = 3;
if (userAction.RoundStop())
{
isPlaying = false;
}
}
}
}
其他类基本没有变化
总结
本次代码因为规则的设计比较简单而简单，其实可以加上生命之之类的功能。
