Android实战打飞机游戏之菜单页面设计(1)
作者：liudao7994
这篇文章主要为大家详细介绍了Android实战打飞机游戏之菜单页面设计，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文目标实现控制小飞机的左右移动、躲避子弹、打boss。
本节实现 开始菜单界面
1、首先 资源文件拷过来
2、划分游戏状态
public static final int GAME_MENU = 0;// 游戏菜单 public static final int GAMEING = 1;// 游戏中 public static final int GAME_WIN = 2;// 游戏胜利 public static final int GAME_LOST = 3;// 游戏失败 public static final int GAME_PAUSE = -1;// 游戏菜单 // 当前游戏状态(默认初始在游戏菜单界面) public static int gameState = GAME_MENU;
定义五种状态
定义完方法后 在绘图方法中 ,实体键 按下方法 ,抬起方法,触屏监听,逻辑方法,switch
//在那几个方法中加这个
switch (gameState) {
case GAME_MENU:
break;
case GAMEING:
break;
case GAME_WIN:
break;
case GAME_LOST:
break;
case GAME_PAUSE:
break;
default:
break;
}
下面再声明一些东西
//声明一个Resources实例便于加载图片 private Resources res = this.getResources(); //声明游戏需要用到的图片资源(图片声明) private Bitmap bmpBackGround;//游戏背景 private Bitmap bmpBoom;//爆炸效果 private Bitmap bmpBoosBoom;//Boos爆炸效果 private Bitmap bmpButton;//游戏开始按钮 private Bitmap bmpButtonPress;//游戏开始按钮被点击 private Bitmap bmpEnemyDuck;//怪物鸭子 private Bitmap bmpEnemyFly;//怪物苍蝇 private Bitmap bmpEnemyBoos;//怪物猪头Boos private Bitmap bmpGameWin;//游戏胜利背景 private Bitmap bmpGameLost;//游戏失败背景 private Bitmap bmpPlayer;//游戏主角飞机 private Bitmap bmpPlayerHp;//主角飞机血量 private Bitmap bmpMenu;//菜单背景 public static Bitmap bmpBullet;//子弹 public static Bitmap bmpEnemyBullet;//敌机子弹 public static Bitmap bmpBossBullet;//Boss子弹
初始化 游戏
/**
* SurfaceView视图创建，响应此函数
*/
@Override
public void surfaceCreated(SurfaceHolder holder) {
screenW = this.getWidth();
screenH = this.getHeight();
initGame();
flag = true;
// 实例线程
th = new Thread(this);
// 启动线程
th.start();
}
/**
* 加载游戏资源
*/
private void initGame() {
//加载游戏资源
bmpBackGround = BitmapFactory.decodeResource(res, R.drawable.background);
bmpBoom = BitmapFactory.decodeResource(res, R.drawable.boom);
bmpBoosBoom = BitmapFactory.decodeResource(res, R.drawable.boos_boom);
bmpButton = BitmapFactory.decodeResource(res, R.drawable.button);
bmpButtonPress = BitmapFactory.decodeResource(res, R.drawable.button_press);
bmpEnemyDuck = BitmapFactory.decodeResource(res, R.drawable.enemy_duck);
bmpEnemyFly = BitmapFactory.decodeResource(res, R.drawable.enemy_fly);
bmpEnemyBoos = BitmapFactory.decodeResource(res, R.drawable.enemy_pig);
bmpGameWin = BitmapFactory.decodeResource(res, R.drawable.gamewin);
bmpGameLost = BitmapFactory.decodeResource(res, R.drawable.gamelost);
bmpPlayer = BitmapFactory.decodeResource(res, R.drawable.player);
bmpPlayerHp = BitmapFactory.decodeResource(res, R.drawable.hp);
bmpMenu = BitmapFactory.decodeResource(res, R.drawable.menu);
bmpBullet = BitmapFactory.decodeResource(res, R.drawable.bullet);
bmpEnemyBullet = BitmapFactory.decodeResource(res, R.drawable.bullet_enemy);
bmpBossBullet = BitmapFactory.decodeResource(res, R.drawable.boosbullet);
}
菜单类 GameMenu
菜单类
包括 初始化绘制按钮和背景图
package com.gsf;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.view.MotionEvent;
/**
*

*/
public class GameMenu {
// 菜单背景图
private Bitmap bmpMenu;
// 按钮图片资源(按下和未按下图)
private Bitmap bmpButton, bmpButtonPress;
// 按钮的坐标
private int btnX, btnY;
// 按钮是否按下标识位
private Boolean isPress;
// 菜单初始化
public GameMenu(Bitmap bmpMenu, Bitmap bmpButton, Bitmap bmpButtonPress) {
this.bmpMenu = bmpMenu;
this.bmpButton = bmpButton;
this.bmpButtonPress = bmpButtonPress;
// X居中，Y紧接屏幕底部
btnX = MySurfaceView.screenW / 2 - bmpButton.getWidth() / 2;
btnY = MySurfaceView.screenH - bmpButton.getHeight();
isPress = false;
}
public void draw(Canvas canvas, Paint paint) {
// 绘制菜单背景图
canvas.drawBitmap(bmpMenu, 0, 0, paint);
if (isPress) {
canvas.drawBitmap(bmpButtonPress, btnX, btnY, paint);
} else {
canvas.drawBitmap(bmpButton, btnX, btnY, paint);
}
}
public void onTouchEvent(MotionEvent event) {
// 获取当前触控位置
int pointX = (int) event.getX();
int pointyY = (int) event.getY();
// 当用户是按下和移动时
if (event.getAction() == MotionEvent.ACTION_DOWN
|| event.getAction() == MotionEvent.ACTION_MOVE) {
// 判定用户是否点击按钮
if (pointX > btnX && pointX < btnX + bmpButton.getWidth()) {
if (pointyY > btnY && pointyY < btnY + bmpButton.getHeight()) {
isPress = true;
} else {
isPress = false;
}
} else {
isPress = false;
}
// 当用于是抬起动作时
} else if (event.getAction() == MotionEvent.ACTION_UP) {
// 判断抬起时是否点击按钮,防止用户移动到别处
if (pointX > btnX && pointX < btnX + bmpButton.getWidth()) {
if (pointyY > btnY && pointyY < btnY + bmpButton.getHeight()) {
isPress = false;//抬起后重置 还原Button状态为未按下状态
//改变当前游戏状态为开始游戏
MySurfaceView.gameState = MySurfaceView.GAMEING;
}
}
}
}
}
然后 在MySurfaceView中使用 GameMenu 使用菜单类
public class MySurfaceView extends SurfaceView implements Callback, Runnable {
private SurfaceHolder sfh;
private Paint paint;
private Thread th;
private boolean flag;
private Canvas canvas;
// 1 定义游戏状态常量
public static final int GAME_MENU = 0;// 游戏菜单
public static final int GAMEING = 1;// 游戏中
public static final int GAME_WIN = 2;// 游戏胜利
public static final int GAME_LOST = 3;// 游戏失败
public static final int GAME_PAUSE = -1;// 游戏菜单
// 当前游戏状态(默认初始在游戏菜单界面)
public static int gameState = GAME_MENU;
// 声明一个Resources实例便于加载图片
private Resources res = this.getResources();
// 声明游戏需要用到的图片资源(图片声明)
private Bitmap bmpBackGround;// 游戏背景
private Bitmap bmpBoom;// 爆炸效果
private Bitmap bmpBoosBoom;// Boos爆炸效果
private Bitmap bmpButton;// 游戏开始按钮
private Bitmap bmpButtonPress;// 游戏开始按钮被点击
private Bitmap bmpEnemyDuck;// 怪物鸭子
private Bitmap bmpEnemyFly;// 怪物苍蝇
private Bitmap bmpEnemyBoos;// 怪物猪头Boos
private Bitmap bmpGameWin;// 游戏胜利背景
private Bitmap bmpGameLost;// 游戏失败背景
private Bitmap bmpPlayer;// 游戏主角飞机
private Bitmap bmpPlayerHp;// 主角飞机血量
private Bitmap bmpMenu;// 菜单背景
public static Bitmap bmpBullet;// 子弹
public static Bitmap bmpEnemyBullet;// 敌机子弹
public static Bitmap bmpBossBullet;// Boss子弹
public static int screenW;
public static int screenH;
//
private GameMenu gameMenu;
/**

public MySurfaceView(Context context) {

sfh = this.getHolder();
