更改每过一关的增长分数 反编译的步骤就不介绍了,我们直接来看反编译得到的文件夹 方法1 :在smali目录下,我们看到org/andengine/,可以知晓游戏是由andengine引擎开发的。打开/res/raw/atlas.txt文件,找到如下信息: 我们直接把number_score_00 01....08的坐标值全部修改为number_score_09的坐标值,重新打包并签名apk,运行测试,0-9关分数一直为9分,10-99关分数一直为99分。 方法2 :打开string.xml,没有找到有用的信息,由于代码是被混淆过的,无法直接根据类名找关键代码。我们换另一种方式,查找string变量,用工具apk改之理打开apk文件,选中smali/com/dotgears/文件夹,在软件右侧面板,按如下操作: 在搜索结果中,有这样一条记录: ,我们不妨猜测该字符串是用来获取分数的,双击来到所在文件,\com\dotgears\h.smali。关键代码如下: # direct methods .method static constructor <clinit>()V .locals 1 const-string v0, "0123456789" sput-object v0, Lcom/dotgears/h;->l:Ljava/lang/String; return-void

3 月,跳不动了?>>> 人生写的第一个Android游戏,名字为炸弹专家,可以在github上找到。 https://github.com/zl-leaf/BombExpert 。各位欢迎吐嘈。 这个游戏使用的是AndEngine的库,链接为 https://github.com/nicolasgramlich/AndEngine ,另外还带有其他的库和Example。要用这个库来写游戏,有第一件事情当然是要搞清楚怎么用这些库了。下面就简单的说一下我对AndEngine提供的其中一个例子的理解。 首先用github下载代码AndEngine和其他库以及Example,如图 与AndEngine相关的库 AndEngine的例子 导入到Eclipse里面,运行(建议用真机运行,因为虚拟机好像有些问题)。 下面要说的代码来自于AndEngineExamples中的一个例子,org.andengine.examples.game.racer里面的RacerGameActivity。 代码如下 package org.andengine.examples.game.racer; import org.andengine.engine.camera.Camera; import org.andengine.engine.camera.hud.controls

3 月,跳不动了?>>> 看完例子熟悉了基本以后就可以开始制作游戏了。 游戏的具体代码我就不贴了,有兴趣可以到我Github上看。下面说一下一些注意的事项 一、声音 1. 背景音乐 作为背景音乐就应该是循环播放的,注意这里是背景音乐,不是背景声音。。。(只有音乐才可以循环播放,我就在这里吃过亏)。 2. 声效。。这个应该没有什么难的 首先,在onCreateEngineOptions()方法里面加点东西 @Override public EngineOptions onCreateEngineOptions() { this.mCamera = new Camera(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT); final EngineOptions engineOptions = new EngineOptions(true,ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(SCREEN_WIDTH, SCREEN_HEIGHT), this.mCamera); engineOptions.getAudioOptions().setNeedsSound(true); engineOptions.getAudioOptions().setNeedsMusic(true); return

Android Toast Messages not working

你离开我真会死。 提交于 2020-02-21 13:16:57
问题 I'm developing a game via Andengine for Android. I have MainActivity class and GameScene class. I use Toast messages in GameActivity. And it is working. Toast.makeText(this, " Hello World", Toast.LENGTH_SHORT).show(); So I wanna use Toast messages in GameScene class. But it doesn't work. Here is the code: Toast.makeText(activity, " Hello World", Toast.LENGTH_SHORT).show(); I have to use "activity" instead of "this". But it doesn't work why? EDITED: when I use second one, an error occurs.

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . I developed a game in andEngine which is almost final. Only problem I am facing now is that when during GamePlay if power button is pressed and Game is resumed again It starts from star. Suppose I am playing

Andengine ask questions with toast?

廉价感情. 提交于 2020-01-24 12:29:46
问题 I wonder if there is any native support for andengine or ADK to ask question-toasts? For example if I press the back button, I want some box to popup asking if I really want to quit the application and give me the option to answer yes or no. 回答1: Better to use alert dialog use this code, hope work same like that @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub switch(keyCode) { case KeyEvent.KEYCODE_BACK: AlertDialog.Builder ab = new

Progress bar while loading Textures in AndEngine

问题 when I start my game black screen comes for a while because resources are being loaded. I went thorough a tutorial which show how to show progress bar while leading resources I followed it and now I can see progress bar. But the problem is this when progress bar is visible every thing else is stopped. And nothing happens. Only a black screen and a progress bar on it. Can any one tell me why every thing is paused and why loadresources and loadscene methods are not working? Please provide a
