关于cocos2dx接Android sdk的一些坑

简单说说UI线程 ：在Android中，有个非常重要的家伙非常霸道，那就是UI线程。这霸道之一：不能被阻塞。 之二：系统对每一个组件的调用都从UI线程分发出去。

简单说说openGL线程：但凡cocos2dx 启动的绘制线程都是openGL线程。就这么多

任何SDK界面的调用，必须从UI线程中调用，所以需要放到主线程中。如果我们直接从GL线程中调用，轻则调用不了，重者程序蹦死。

解决办法：

得到主线程的handler，这里简单说一种，就是在onCreate中new一个静态handler。

或者new Handler(Looper.getMainLooper())，且叫mainHandler吧，

启动一个线程，

Bullet(Cocos2dx)之交叉编译Android,集成到cocos2dx3.x

首先将src文件夹复制到jni文件夹，没有可以新建一个

新建两个文件Android.mk，Application.mk

Application.mk内容如下：

APP_ABI:=armeabiarmeabi-v7ax86

APP_PLATFORM:=android-8

APP_STL:=stlport_static

Android.mk内容如下：

LOCAL_PATH:=$(callmy-dir)

include$(CLEAR_VARS)

LOCAL_MODULE :=bullet_static(可随便起)

LOCAL_MODULE_FILENAME:=libbullet（可随便起）

LOCAL_C_INCLUDES:=src/(头文件位置)

（源文件，要列出所有用到的，这里用到BulletSoftBodyBulletDynamics

BulletCollisionsLinearMath）

最后还要加上一句，表示生成静态库如果将STATIC该文SHARED则生成动态库

include$(BUILD_STATIC_LIBRARY)

然后进入命令行

进入jni所在目录

ndk-build

等待编译完成

将三个目录下的libbullet.a分别复制到cocos2dx的安装目录下的

安装目录\Cocos\frameworks\cocos2d-x\prebuilt\android\相应文件下

进入Cocos\frameworks\cocos2d-x\external

新建文件夹Bullet，在Bullet下新建prebuild-mk

将Box2D\prebuild-mk下的Android.mk复制到Bullet/prebuild-mk

修改如下3行

LOCAL_MODULE:=bullet_static

LOCAL_MODULE_FILENAME:=libbullet

LOCAL_SRC_FILES:=../../../prebuilt/android/$(TARGET_ARCH_ABI)/libbullet.a

复制头文件

将bullet3的src的所有文件复制到新建的Bullet文件下

删除不是.h的所有文件

下一步任务繁重，

将所有用到BulletCollisionBulletDynamicsBulletSoftBodyLinearMath目录下的include都加上Bullet/,可以使用Notepad++在Bullet目录搜索Bullet,并替换为Bullet/Bullet，LinearMath并替换为Bullet/LinearMath

进入Cocos\frameworks\cocos2d-x\cocos\prebuilt-mk

在Android.mk

在LOCAL_WHOLE_STATIC_LIBRARIES+=Box2d_static下面添加

LOCAL_WHOLE_STATIC_LIBRARIES+=bullet_static

$(callimport-module,Box2D/prebuilt-mk)下面添加

$(callimport-module,Bullet/prebuilt-mk)

至此已经完成编译静态库

Cocos2d-x-4.0在VS2019环境下的环境搭建（官方下载的cocos2dx压缩包）

Cocos2dx环境搭建

写这篇文章的目的是，方便只装了VS2019不想装其他版本VS的新人，学会搭建cocos2dx环境，少走弯路。

搭建前的环境准备

1. 需要先到python官网下载安装python2，并配置好环境变量。
2. 配置cmake的环境变量，由于已经安装了VS2019所以直接使用VS的cmake，所在路径为

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin

开始搭建

首先使用cmake构建从官网下载的cocos2dx源码。编译的前两步和官网介绍的一样，先打开命令行跳转到cocos所在的目录，然后创建一个build文件，进入build文件。之后使用的命令和官网给出的不一样。使用的命令为

cmake .. -G"Visual Studio 16 2019" -A Win32

这里给不太了解cmake的朋友解释一下，cmake命令后的两个点是返回上一级目录，也就是指定需要被构建的CMakeList所在的路径，-G命令行参数的作用是指定要生成的项目类型，这里指定的是VS2019，有一点不同的是生成VS2019项目不像生成旧版的VS项目一样可以在引号内指定编译器架构，需要在引号外部用-A指定编译器架构。这里指定为Win32架构，默认不指定的话构建VS2019项目使用的是x64架构，为了避免不必要的麻烦，请一定要指定为Win32架构。等待cmake运行完毕，就可以按照官方文档中的介绍使用和学习了。打开build文件中的Cocos2d-x.sln，选择想看的项目右键设为启动项目，运行，就可以看着项目运行效果学习cocos的例程。

这是在segmentfault的第一篇文章，也是自己新的开始。

cocos2d-x中的pvr.ccz压缩图片

• 前几天打开了保卫萝卜的游戏，看到了其中有使用plist 和 *.pvr。czz文件。
  
  在网上查了一下说pvr。czz不能用图片名调用，测试了一下发现可以用，写下代码：
  
  1.首先将texturepacker 软件生产的文件，111.pliost 和111.pvr.czz文件拷贝到资源文件夹中。
  
  pvr.czz文件生产图片时一定要是一个正方形，否则据说编译到别的平台上有问题 www.it165.net

  2.添加测试代码

  
  
  view source print ?
  01. voidHelloWorld::showPVR()

  02. {

  03. //打开pvr支持

  04. CCTexture2D::PVRImagesHavePremultipliedAlpha(true);

  05. //添加到帧序列中

  06. CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("111.plist"07. //通过一个镇图片生产精灵

  08. CCSprite *sp =CCSprite::createWithSpriteFrameName("4.png"09. sp->setPosition(ccp(100,));

  10. this->addChild(sp);

  11. }
