Can we expect an updated Cocos2d-X 3.0 documentation soon, or just when a final will arrive?
whiteape, I’ve add some documents’ link in this release note. And we’re still adding more docs for v3.0 in these coming months.
Was hoping the label kerning bug would of been fixed in this latest beta release but still not fixed
The rendering documents link is broken
1.Looking forward to the release version! :D
2.Simple HTML tag support.
Internal error on intro new renderer access,site cant view,please fix it:
Will the release version come out before end of April?
Any document related deprecated method. install.sh file missing for mac.
ARC compatible but some function missing……
So, this CocosStudio will be Windows only? Any plans in porting it to OSX?
Cocos2d-html5 v2.2.2 link give me this error

Cocostudio will support mac and linux too. In fact, it is in progress.
@lino lino, thanks for your report. It has been fixed now.
is there a possible eta for adding the winphone 8 support to the project_creator.py?
thx for the wicked release
The part involving education and learning to remove feudalism and relative involving master and servant. The slaves will get
liberation from their pros when they have education and learning and perhaps they are aware about the life span all-around these.

& cocos2d-x 通过JNI实现c/c++和Android的java层函数互调
本文主要实现两个功能:
(1)通过Android sdk的API得到应用程序的包名(PackageName)，然后传递给c++层函数。
(2)通过c++函数调用Android的java层函数，显示一个对话框，点击按钮退出程序。
1. 首先来简单学习一下JNI的相关知识，我中简单实现了怎么在Android Java层调用c++函数。要想使用JNI，必须得包含头文件，android是使用ndk编译c/c++的，这里jni.h文件位于：\android-ndk-r8b\platforms\android-14\arch-arm\usr\include\jni.h，该文件定义了所有和JNI相关的数据类型和接口。下面是相关代码片段：
# include &inttypes.h&
typedef uint8_
/* unsigned 8 bits */
typedef int8_
/* signed 8 bits */
typedef uint16_
/* unsigned 16 bits */
typedef int16_
/* signed 16 bits */
typedef int32_
/* signed 32 bits */
typedef int64_
/* signed 64 bits */
typedef fl
/* 32-bit IEEE 754 */
typedef dou
/* 64-bit IEEE 754 */
typedef unsi
/* unsigned 8 bits */
/* signed 8 bits */
/* unsigned 16 bits */
typedef sh
/* signed 16 bits */
/* signed 32 bits */
/* signed 64 bits */
typedef fl
/* 32-bit IEEE 754 */
typedef dou
/* 64-bit IEEE 754 */
/* "cardinal indices and sizes" */
#ifdef __cplusplus
* Reference types, in C++
class _jobject {};
class _jclass : public _jobject {};
class _jstring : public _jobject {};
class _jarray : public _jobject {};
class _jobjectArray : public _jarray {};
class _jbooleanArray : public _jarray {};
class _jbyteArray : public _jarray {};
class _jcharArray : public _jarray {};
class _jshortArray : public _jarray {};
class _jintArray : public _jarray {};
class _jlongArray : public _jarray {};
class _jfloatArray : public _jarray {};
class _jdoubleArray : public _jarray {};
class _jthrowable : public _jobject {};
typedef _jobject*
typedef _jclass*
typedef _jstring*
typedef _jarray*
typedef _jobjectArray*
typedef _jbooleanArray* jbooleanA
typedef _jbyteArray*
typedef _jcharArray*
typedef _jshortArray*
typedef _jintArray*
typedef _jlongArray*
typedef _jfloatArray*
typedef _jdoubleArray*
typedef _jthrowable*
typedef _jobject*
#else /* not __cplusplus */
* Reference types, in C.

typedef jarray

typedef jobjec
#endif /* not __cplusplus */
我们经常用到的是JNIEnv*，它是一个c结构体，封装了许多常用的函数，如：
struct _JNIEnv {
/* it does not seem to be entirely opaque */
const struct JNINativeInterface*
#if defined(__cplusplus)
jint GetVersion()
{ return functions-&GetVersion(this); }
jclass DefineClass(const char *name, jobject loader, const jbyte* buf,
jsize bufLen)
{ return functions-&DefineClass(this, name, loader, buf, bufLen); }
jclass FindClass(const char* name)
{ return functions-&FindClass(this, name); }
// 这里省略其他函数...
cocos2d-x引擎对jni的操作进行了封装，提供了一个非常好用的类:JniHelper，定义了一些常用的接口，该文件位于cocos2dx/platform/android/jni目录下。下面看看JniHelper.h源码：
typedef struct JniMethodInfo_
} JniMethodI
class CC_DLL JniHelper
static JavaVM* getJavaVM();
static void setJavaVM(JavaVM *javaVM);
static const char* getExternalAssetPath();
static void setExternalAssetPath(const char* externalAssetPath);
static jclass getClassID(const char *className, JNIEnv *env=0);
static bool getStaticMethodInfo(JniMethodInfo &methodinfo, const char *className, const char *methodName, const char *paramCode);
static bool getMethodInfo(JniMethodInfo &methodinfo, const char *className, const char *methodName, const char *paramCode);
static std::string jstring2string(jstring str);
static JavaVM *m_psJavaVM;
static std::string m_externalAssetP
下面来解释JniHelper的两个常用函数：
(1)getStaticMethodInfo
用来判断Java的类静态函数是否存在，并初始化结构体JniMethodInfo，该结构体封装了JNIEnv*和java.lang.Class对象、函数ID。这样就可以使用JNIEnv*调用 CallStaticXXXMethod(jclass clazz, jmethodID methodID, …)和 CallXXXMethod(jobject obj, jmethodID methodID, …)等常用函数(XXX替换为函数返回值类型，如：Void，Int等)。
第一个参数为JniMethodInfo，第二个参数是类的绝对路径，第三个参数是函数名，第四个参数是函数签名(参数和返回类型)，示例代码如下：
if(JniHelper::getStaticMethodInfo(t, CLASS_NAME, "showTipDialog", "(Ljava/lang/SLjava/lang/S)V"))
关于类型签名，请对照下图：
(2)getMethodInfo
该函数与getStaticMethodInfo类似，用于Java类的非静态函数。
2. 下面开始实现文章开头所述的两个功能，本文是在demo的基础上添加的。
(1)利用cocos2d-x创建一个Android工程，名为JniTest，包名为com.alexzhou.jni，此时该包下会自动生成一个JniTest.java文件。
(2)首先来实现把应用程序的包名传递给c++函数，在包下创建JniTestHelper.java，该类封装了给c++调用的函数，添加如下代码：
private static Handler mH
public static void init(Handler handler)
JniTestHelper.mHandler =
public static native void setPackageName(String packageName);
(3)打开JniTest.java，在onCreate函数中添加下面的代码：
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
JniTestHelper.init(mHandler);
JniTestHelper.setPackageName(this.getPackageName());
(4)java层的代码已经完成了，下面来编写jni层代码，在/jni/hellocpp/下创建test.h和test.cpp文件，test.h文件暂时不添加任何函数，代码如下：
#ifndef TEST_H
#define TEST_H
#include "cocos2d.h"
#include &jni.h&
#include "platform/android/jni/JniHelper.h"
#include "test.h"
#include "JniTest.h"
#define CLASS_NAME "com/alexzhou/jni/JniTestHelper"
using namespace cocos2d;
extern "C"
void Java_com_alexzhou_jni_JniTestHelper_setPackageName(JNIEnv *env, jobject thiz, jstring packageName)
const char *pkgName = env-&GetStringUTFChars(packageName, NULL);
setPackageName(pkgName);
env-&ReleaseStringUTFChars(packageName, pkgName);
必须加上extern “C”，声明以c语言的方式进行编译，因为c++和c在编译时生成的函数签名不一样，可以在网上查找相关资料，不然运行的时候会出现链接错误。
(5)现在编写c++函数，在Classes目录下创建JniTest.h，代码如下：
#ifndef JNI_TEST_H
#define JNI_TEST_H
#include "cocos2d.h"
using namespace cocos2d;
void setPackageName(const char *packageName)
CCLog("packageName: %s", packageName);
(6)修改jni/Android.mk文件的LOCAL_SRC_FILES值 ，内容如下：
LOCAL_SRC_FILES := hellocpp/main.cpp \
hellocpp/test.cpp
(7)编译运行，因为我是使用cygwin编译的，而且Android项目不在cocos2d-x的根目录下，所以需要修改build_native.sh，修改COCOS2DX_ROOT和NDK_MODULE_PATH的值，把当前cocos2d-x项目的路径添加到NDK_MODULE_PATH，修改后的值：
COCOS2DX_ROOT="/cygdrive/e/cocos2d-x/cocos2d-2.0-x-2.0.4"
"NDK_MODULE_PATH=${COCOS2DX_ROOT}:${COCOS2DX_ROOT}/cocos2dx/platform/third_party/android/prebuilt:${APP_ROOT}"
运行结果：
（8）现在来实现通过c++函数调用java层函数，显示一个对话框。在JniTestHelper.java添加如下代码：
public static native void exitApp();
private static void showTipDialog(final String title, final String text)
Message msg = mHandler.obtainMessage();
msg.what = JniTest.SHOW_DIALOG;
DialogMessage dm = new DialogMessage();
dm.title =
msg.sendToTarget();
(9)创建一个DialogMessage.java,封装dialog要显示的数据。
author:alexzhou
public class DialogMessage {
(10) 修改JniTest.java，添加显示对话框的函数：
public static final int SHOW_DIALOG = 0x0001;
private Handler mHandler = new Handler()
public void handleMessage(Message msg) {
switch(msg.what)
case SHOW_DIALOG:
DialogMessage dm = (DialogMessage)msg.
new AlertDialog.Builder(JniTest.this)
.setTitle(dm.title)
.setMessage(dm.msg).setNegativeButton("cancle", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
JniTestHelper.exitApp();
.create().show();
(11)在test.h和test.cpp中添加显示对话框的接口：
extern "C"
void showTipDialog(const char *title, const char *msg);
extern "C"
void showTipDialog(const char *title, const char *msg)
JniMethodI
if(JniHelper::getStaticMethodInfo(t, CLASS_NAME, "showTipDialog", "(Ljava/lang/SLjava/lang/S)V"))
jstring jTitle = t.env-&NewStringUTF(title);
jstring jMsg = t.env-&NewStringUTF(msg);
t.env-&CallStaticVoidMethod(t.classID, t.methodID, jTitle, jMsg);
t.env-&DeleteLocalRef(jTitle);
t.env-&DeleteLocalRef(jMsg);
void Java_com_alexzhou_jni_JniTestHelper_setPackageName(JNIEnv *env, jobject thiz, jstring packageName)
const char *pkgName = env-&GetStringUTFChars(packageName, NULL);
setPackageName(pkgName);
env-&ReleaseStringUTFChars(packageName, pkgName);
void Java_com_alexzhou_jni_JniTestHelper_exitApp(JNIEnv *env, jobject thiz)
exitApp();
(12) 修改Classes目录下的JniTest.h，添加代码：
void exitApp()
CCDirector::sharedDirector()-&end();
(13)到此为止，所有代码都已经完成了，代码比较简单就不详细解释了，现在编译运行，效果如下：
