文章标签 设计 编程 3d 游戏 魔鬼 hw4 牧师

本文主要是介绍3D游戏编程与设计Hw4（牧师与魔鬼），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

  • 游戏中提及的事物：物体牧师、物体魔鬼、物体河岸、物体水域、物体船。

玩家动作表（规则表）

玩家玩家动作
船点击Go按钮则行进（船上必须有一个人）
魔鬼/牧师点击岸上的玩家则跑到船上，同理返回岸上。岸边的牧师数必须等于或大于魔鬼数，否则游戏失败

UML类图
在这里插入图片描述
代码参考学长博客实现：

}

Character.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Character {readonly GameObject character;readonly int type; //0-priest 1-devilreadonly Moveable moveableScript;// 移动脚本组件readonly GUIClick _GUIClick;// 响应鼠标点击组件private bool isOnBoat;// 是否在船上private bool isFinished;//是否已经过河// 构造函数，根据传入的字符串选择创建牧师对象或者魔鬼对象public Character(string sel){// 动态加载预制if(sel == "priest"){character = Object.Instantiate(Resources.Load("Prefabs/priest", typeof(GameObject)),Vector3.zero, Quaternion.identity, null) as GameObject;type = 0;}else{character = Object.Instantiate(Resources.Load("Prefabs/devil", typeof(GameObject)),Vector3.zero, Quaternion.identity, null) as GameObject;type = 1;}// 为对象添加移动和点击响应组件moveableScript = character.AddComponent (typeof(Moveable)) as Moveable;_GUIClick = character.AddComponent(typeof(GUIClick)) as GUIClick;_GUIClick.bindCharacter(this);// 初始化变量isOnBoat = false;isFinished = false;}public int getType(){return type;}public void setName(string name) {character.name = name;}public string getName() {return character.name;}public void getOnBoat(Boat boat){// 设置transform为船的子组件，这样当船移动的时候就可以随着船移动character.transform.parent = boat.getGameobj().transform;isOnBoat = true;}public void getOffBoat(){character.transform.parent = null;isOnBoat = false;}public void getOnLand(Land land){if(land.getType() == 0){isFinished = false;}else{isFinished = true;}isOnBoat = false;}public bool getIsOnBoat(){return isOnBoat;}public void setPosition(Vector3 pos){character.transform.position = pos;}public void moveToPosition(Vector3 pos){moveableScript.setDestination(pos);}public bool getIsFinished(){return isFinished;}// 重置对象public void reset(){moveableScript.reset();// 如果对象已经过河if(isFinished){// 通过导演对象获取当前场景的控制器，取得其控制的Land对象Land endLand = (Director.getInstance ().currentSceneController as FirstController).endLand;endLand.leaveLand(this);Land startLand = (Director.getInstance ().currentSceneController as FirstController).startLand;getOnLand(startLand);setPosition(startLand.getOnLand(this));}// 如果对象在船上if(isOnBoat){getOffBoat();Land startLand = (Director.getInstance ().currentSceneController as FirstController).startLand;Boat boat = (Director.getInstance ().currentSceneController as FirstController).boat;boat.removePassenger(this);getOnLand(startLand);setPosition(startLand.getOnLand(this));}character.transform.parent = null;        }}

以上是预制物体的代码，实现了程序运行后物体自动生成而不是在Scene界面自己做。

接下来是控制部分：
SceneController.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public interface SceneController {void loadResources ();void checkGameStatus();
}

FirstController.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class FirstController : MonoBehaviour, SceneController, UserAction{readonly Vector3 water_pos = new Vector3(0,-0.4F,0);// 河流预制的位置public Land startLand;// 起始河岸public Land endLand;// 终点河岸public Boat boat;// 船public int status;//游戏状态 0-gaming 1-lose 2-win private Character[] characters;// 六个游戏角色private _GUI userGUI;// GUI组件void Awake() {// 将自身设置为当前场记Director director = Director.getInstance ();director.currentSceneController = this;// 将GUI作为一个组件userGUI = gameObject.AddComponent <_GUI>() as _GUI;characters = new Character[6];// 加载游戏资源loadResources();}// 实现SceneController接口，加载游戏资源public void loadResources() {GameObject water = Instantiate (Resources.Load ("Prefabs/river", typeof(GameObject)), water_pos, Quaternion.identity, null) as GameObject;water.name = "water";startLand = new Land ("start");endLand = new Land ("end");boat = new Boat();loadCharacter ();}// 实现SceneController接口，检查游戏状态 0->not finish, 1->lose, 2->winpublic void checkGameStatus() {	// 船在出发点int startNumOfPriest = startLand.getNumOfPriest();int startNumOfDevil = startLand.getNumOfDevil();int endNumOfPriest = endLand.getNumOfPriest();int endNumOfDevil = endLand.getNumOfDevil();int boatNumOfPriest = boat.getNumOfPriest();int boatNumOfDevil = boat.getNumOfDevil();if(endNumOfPriest + endNumOfDevil + boatNumOfPriest + boatNumOfDevil == 6){status = 2;return ;}if(boat.getCurPosition() == 1){if((startNumOfPriest  < startNumOfDevil && startNumOfPriest > 0)||(endNumOfPriest +  boatNumOfPriest < endNumOfDevil + boatNumOfDevil && endNumOfPriest +  boatNumOfPriest > 0)){status = 1;return ;}}else{if((startNumOfPriest + boatNumOfPriest < startNumOfDevil + boatNumOfDevil && startNumOfPriest + boatNumOfPriest > 0) || (endNumOfPriest < endNumOfDevil && endNumOfPriest > 0)){status = 1;return ;}}status = 0;}// 加载游戏对象private void loadCharacter() {for (int i = 0; i < 3; i++) {Character ch = new Character("priest");ch.setName("priest" + i);ch.getOnLand(startLand);ch.setPosition (startLand.getOnLand(ch));characters[i] = ch;}for (int i = 0; i < 3; i++) {Character ch = new Character("devil");ch.setName("devil" + i);ch.setPosition (startLand.getOnLand(ch));ch.getOnLand(startLand);characters [i+3] = ch;}}// 实现UserAction接口的goButtonIsClicked函数public void goButtonIsClicked(){if(!boat.isEmpty()){boat.move();checkGameStatus();}}// 实现UserAction接口的characterIsClicked函数public void characterIsClicked(Character ch){// 角色在船上if(ch.getIsOnBoat()){if(boat.getCurPosition() == 0){ch.moveToPosition(startLand.getOnLand(ch));ch.getOnLand(startLand);}else{ch.moveToPosition(endLand.getOnLand(ch));ch.getOnLand(endLand);}ch.getOffBoat();boat.removePassenger(ch);}// 角色在岸上else{if(!boat.isFull()){if(ch.getIsFinished() && boat.getCurPosition() == 1){ch.getOnBoat(boat);endLand.leaveLand(ch);ch.moveToPosition(boat.getEmptyPosition());boat.addPassenger(ch);}if(!ch.getIsFinished() && boat.getCurPosition() == 0){ch.getOnBoat(boat);startLand.leaveLand(ch);ch.moveToPosition(boat.getEmptyPosition());boat.addPassenger(ch);}}}}// 重置游戏public void restart(){status = 0;for(int i = 0;i < 6;++i){characters[i].reset();}boat.reset();startLand.reset();endLand.reset();		}}

Director.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Director : System.Object{private static Director _instance;public SceneController currentSceneController { get; set; }public static Director getInstance() {if (_instance == null) {_instance = new Director ();}return _instance;}
}

视觉部分（点击事件聚集处）
GUI.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class _GUI : MonoBehaviour{private SceneController sc;private UserAction ac;private GUIStyle style;private int status;private Texture2D priest;private Texture2D devil;private Texture2D rule;void Start(){style = new GUIStyle();style.fontSize = 40;// 获得控制器，通过控制器更新model部分的数据sc = Director.getInstance ().currentSceneController;ac = Director.getInstance().currentSceneController as UserAction;status = (Director.getInstance ().currentSceneController as FirstController).status;// 动态加载图片priest = Instantiate (Resources.Load ("Pictures/牧师", typeof(Texture2D))) as Texture2D;devil = Instantiate (Resources.Load ("Pictures/恶魔", typeof(Texture2D))) as Texture2D;rule = Instantiate (Resources.Load ("Pictures/规则", typeof(Texture2D))) as Texture2D;// Debug.Log("Screen.width"+Screen.width);// Debug.Log(" Screen.height"+ Screen.height);}void OnGUI(){// 同步游戏状态status = (Director.getInstance ().currentSceneController as FirstController).status;if(GUI.Button(new Rect(1300,850, 120, 120),"GO")){if(status == 0){ac.goButtonIsClicked();}}if(GUI.Button(new Rect(1600,850, 120, 120), "Restart")){ac.restart();}if(status == 1){GUI.Label(new Rect(800,100,300,250),devil);GUI.Label(new Rect(840, 400, 100, 50), "You lose!",style);}if(status == 2){GUI.Label(new Rect(800,100,300,250),priest);GUI.Label(new Rect(840, 400, 100, 50), "You win!",style);}GUI.Label(new Rect(0,800,1500,1500),rule);}
}

GUIClick.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class GUIClick : MonoBehaviour{UserAction action;Character bindingCharacter;// 组件当前绑定的角色对象SceneController sc;int status;// 游戏状态public void bindCharacter(Character ch){bindingCharacter = ch;status = (Director.getInstance ().currentSceneController as FirstController).status;}void Start(){action = Director.getInstance().currentSceneController as UserAction;sc = Director.getInstance().currentSceneController;}void OnMouseDown(){// 同步游戏状态status = (Director.getInstance ().currentSceneController as FirstController).status;// 只有在游戏中点击才有效if(status == 0){action.characterIsClicked(bindingCharacter);}}
}

剩下两个组件：
Moveabel.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Moveable : MonoBehaviour{readonly float speed = 10;int moving_status;	// 0->not moving, 1->moving to middle, 2->moving to destVector3 dest;Vector3 middle;void Update() {if (moving_status == 1) {transform.position = Vector3.MoveTowards (transform.position, middle, speed * Time.deltaTime);if (transform.position == middle) {moving_status = 2;}} else if (moving_status == 2) {transform.position = Vector3.MoveTowards (transform.position, dest, speed * Time.deltaTime);if (transform.position == dest) {moving_status = 0;}}}public void setDestination(Vector3 _dest) {dest = _dest;middle = _dest;if (_dest.y == transform.position.y) {	// boat movingmoving_status = 2;}else if (_dest.y < transform.position.y) {	// character from coast to boatmiddle.y = transform.position.y;} else {								// character from boat to coastmiddle.x = transform.position.x;}moving_status = 1;}public void reset() {moving_status = 0;}
}

UserAction.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public interface UserAction {public void goButtonIsClicked();public void characterIsClicked(Character characterCtrl);public void restart();
}
