在��用cocos2d-x发布Android�q�_��游戏�Ӟ��游戏中可能需要显�C�Z��文字体，或者想昄��漂亮的自定义字体,�q�怎么办呢�Q?br />cocos2d-x中字体标�{�提供了CCLabelAtlas, CCLabelBMFont CCLabelTTF

1.CCLabelAtlas速度快，支持��单有限的几个字符或数字集�?br />
2.CCLabelBMFont
我们可以用CCLabelBMFont来加载字体编辑器生成�?plist文�g�Q�但是当昄��的文字很多时�Q�这�U�做法就有点�Ҏ��费力�?br />如：我们��x��C�游戏中剧情介绍

3.CCLabelTTF
支持选择一�U�字体来昄��文字�Q�但是只支持�pȝ��中默认字�?br />

CCLabelTTF* pLabel = CCLabelTTF::create("Hello World", "Arial", 24);

问题�Q�我们在Android游戏中想昄��游戏剧情�Q�想用自己指定的一�U�字体gril.ttf(非系�l�默认字�?,怎么�?/strong>

其实cocos2d-x已经提供了帮我们实现�?br />构造CCLabelTTF中指定的字体名传�l�了CCTexture2D
void CCLabelTTF::updateTexture()
{
    CCTexture2D *tex;
    if (m_tDimensions.width == 0 || m_tDimensions.height == 0)
    {
        tex = new CCTexture2D();
        tex->initWithString(m_string.c_str(), m_pFontName->c_str(), m_fFontSize * CC_CONTENT_SCALE_FACTOR()) ;
    }
    else
    {
        tex = new CCTexture2D();
        tex->initWithString(m_string.c_str(),
                            CC_SIZE_POINTS_TO_PIXELS(m_tDimensions),
                            m_hAlignment,
                            m_vAlignment,
                            m_pFontName->c_str(),
                            m_fFontSize * CC_CONTENT_SCALE_FACTOR());
    }

   .
}
CCTexture2D又将字体名传�l�了CCImage
(PS:�q�里调用的是android�q�_��下的CCImage�c?./platform/android/CCImage.h)
而不是win32�q�_��下的CCImage�c?./platform/win32/CCImage.h) )

android�q�_��下的CCImage
bool CCImage::initWithString(
                               const char *    pText,
                               int             nWidth/* = 0*/,
                               int             nHeight/* = 0*/,
                               ETextAlign      eAlignMask/* = kAlignCenter*/,
                               const char *    pFontName/* = nil*/,
                               int             nSize/* = 0*/)
{
    bool bRet = false;

    do
    {
        CC_BREAK_IF(! pText);

        BitmapDC &dc = sharedBitmapDC();

        CC_BREAK_IF(! dc.getBitmapFromJava(pText, nWidth, nHeight, eAlignMask, pFontName, nSize));

        // assign the dc.m_pData to m_pData in order to save time
        m_pData = dc.m_pData;
        CC_BREAK_IF(! m_pData);

        m_nWidth    = (short)dc.m_nWidth;
        m_nHeight   = (short)dc.m_nHeight;
        m_bHasAlpha = true;
        m_bPreMulti = true;
        m_nBitsPerComponent = 8;

        bRet = true;
    } while (0);

    return bRet;
}

然后调用了android�q�_��下的BitmapDC
  bool getBitmapFromJava(const char *text, int nWidth, int nHeight, CCImage::ETextAlign eAlignMask, const char * pFontName, float fontSize)
    {
        JniMethodInfo methodInfo;
        if (! JniHelper::getStaticMethodInfo(methodInfo, "org/cocos2dx/lib/Cocos2dxBitmap", "createTextBitmap",
            "(Ljava/lang/String;Ljava/lang/String;IIII)V"))
        {
            CCLOG("%s %d: error to get methodInfo", __FILE__, __LINE__);
            return false;
        }


}

�q�里昄��了调用JAVA代码Cocos2dxBitmap.java下的createTextBitmap函数

  /*
     * @width: the width to draw, it can be 0
     * @height: the height to draw, it can be 0
     */
    public static void createTextBitmap(String content, String fontName,
            int fontSize, int alignment, int width, int height){

        content = refactorString(content);
        Paint paint = newPaint(fontName, fontSize, alignment);

        TextProperty textProperty = computeTextProperty(content, paint, width, height);

        int bitmapTotalHeight = (height == 0 ? textProperty.totalHeight:height);

        // Draw text to bitmap
        Bitmap bitmap = Bitmap.createBitmap(textProperty.maxWidth,
                bitmapTotalHeight, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);

        // Draw string
        FontMetricsInt fm = paint.getFontMetricsInt();
        int x = 0;
        int y = computeY(fm, height, textProperty.totalHeight, alignment);
        String[] lines = textProperty.lines;
        for (String line : lines){
            x = computeX(paint, line, textProperty.maxWidth, alignment);
            canvas.drawText(line, x, y, paint);
            y += textProperty.heightPerLine;
        }

        initNativeObject(bitmap);
    }

�?strong style="font-size: 13.333333969116211px; ">newPaint函数中调用了字体加蝲

private static Paint newPaint(String fontName, int fontSize, int alignment){
        Paint paint = new Paint();
        paint.setColor(Color.WHITE);
        paint.setTextSize(fontSize);
        paint.setAntiAlias(true);

        /*
         * Set type face for paint, now it support .ttf file.
         */
        if (fontName.endsWith(".ttf")){ //字体需�?ttf�l�束
try {
                //Typeface typeFace = Typeface.createFromAsset(context.getAssets(), fontName);
                 Typeface typeFace = Cocos2dxTypefaces.get(context, fontName);
                  paint.setTypeface(typeFace);
             } catch (Exception e){
                 Log.e("Cocos2dxBitmap",
                     "error to create ttf type face: " + fontName);

                 /*
                  * The file may not find, use system font
                  */
                 paint.setTypeface(Typeface.create(fontName, Typeface.NORMAL));
             }
        }
        else {
            paint.setTypeface(Typeface.create(fontName, Typeface.NORMAL));
        }

.......

        return paint;
    }

�Q�PS:Typeface�c�d��义字体和字体内在的类型。这个类被用在画�W�Paint讄��的时候，比如用textSize,textSkewX和textScale讄��来指定text在画的时候如何来昄��和测量�?/div>android中用Typeface来指定字体）

另一炚w��要注意的是：字体需�?ttf�l�束

使用�Ҏ���Q?br />1.在proj.android\assets文�g夹中��d��girl.ttf
2.�E�序中调用对应的字体��可以了

CCSize size = CCDirector::sharedDirector()->getWinSize();
    CCLabelTTF* label = CCLabelTTF::create("��女HelloWorld", "girl.ttf", 24);
    label->setPosition(ccp(size.width/2, size.height/2));
    addChild(label);

3.如果你需要显�C�汉字，则需要将包含有字�W�串的文�?�?cpp)转换为UTF-8格式�~�码�Q�否则会昄��q��

IOS和win32�q�_��没有��试�Q�相信的差不�?br />
附上��试囄��Q?br />

哈哈可以在游戏中打包自己惌��的字体啦

cocos2d-x 贝塞��曲�U�之游戏应用

Let me see see — Fri, 24 Aug 2012 10:04:00 GMT

一.贝赛��曲�U�简�?br />贝塞��曲�U�是应用于二�l�图形应用程序的数学曲线。曲�U�的定义有四个点�Q��v始点、终止点�Q�也�U�锚点）以及两个�怺�分离的中间点。滑动两个中间点�Q�贝塞尔曲线的�Ş状会发生变化

p0��L��Q�p3是终点，p1,p2是控制点
http://en.wikipedia.org/wiki/B%C3%A9zier_curve

�?游戏应用

我们可能需要在游戏中模拟导�Ҏ��的�U�d��轨迹�Q�用才cocos2d-x下的bezier可以��L��的模拟出�?br />cocos2d-x下�ؓ我们提供了两个action CCBezierBy和CCBezierTo�Q��用也很简单，只需要填充结构体�Q?br />

ccBezierConfig tr0;
        tr0.endPosition=ccp(280, 240);
        tr0.controlPoint_1=ccp(40, 400);
        tr0.controlPoint_2=ccp(280, 80);

        CCActionInterval* bezierForward = CCBezierBy::create(1.f, tr0);

我们只需要提供两个控制点和一个终点位�|�就可以了，�q�里要注意的�?br />CCBezier�q�个action是以当前位置��v始点的，两个控制点和�l�点都是相对于�v始点的偏�U�d�?/span>
如：tr0.endPosition = ccp(280,240); 是相对于起始点的偏移

�? 游戏实例

        {
            CCSpriteFrame* frame = CCSpriteFrame::create(pTexture,
                CCRectMake(j * frame_width, i * frame_height, frame_width, frame_height));
            spriteFramesArray->addObject(frame);
        }

        //以键值�Ş式存贮动��d��CCAnimationCatch�?/span>
        float frameTime = 1.f / (mSpeed * flyFrames);

发布release版本的apk软�g

Let me see see — Wed, 15 Aug 2012 02:11:00 GMT

Signing in Release Mode

When your application is ready for release to other users, you must:

Obtain a suitable private key
Compile the application in release mode
Sign your application with your private key
Align the final APK package

发布release版本要有4�?br />官方说明�Q?nbsp; http://developer.android.com/tools/publishing/app-signing.html#releasecompile

�q�x��通过Eclipse生成在bin目录下的apk文�g�Q�都是debug版的�Q�如何创建release版的软�g呢？
其实�q�是挺简单的�?nbsp;

1. 通过java自带的keytool工具�Q�创建release版的keystore

keytool -genkey -v -keystore keystore_name.keystore -alias alias_name -keyalg RSA -validity 10000

keystore_name.keystore�Q�要创徏的release版keystore的文件名
alias_name�Q�别名？取个好记点的名字吧，后面�q�要用到�?�Q�填写配�|�文�?
-keyalg RSA�Q�通过RSA��法生成
-validity 10000�Q�有效期�Q�单位是�?nbsp;

如果java环境配置正常�Q�输入命令后会出��C��列信�?nbsp;
Enter keystore password:�Q�keystore的密码）
Re-enter new password:�Q�确认keystore的密码）
What is your first and last name?
  [Unknown]:  �Q�姓名，用自己喜�Ƣ的名字吧，不知道会昄��在哪里）
What is the name of your organizational unit?
  [Unknown]:  �Q�组�l�单位）
What is the name of your organization?
  [Unknown]:  �Q�组�l�，不知道和上面那个有什么区别）
What is the name of your City or Locality?
  [Unknown]:  �Q�城市）
What is the name of your State or Province?
  [Unknown]:  �Q�州�Q�省�Q�县�Q?nbsp;
What is the two-letter country code for this unit?
  [Unknown]:  CN
Is CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=CN correct?
  [no]:  yes �Q�确认输入的信息�Q?nbsp;

Generating 1,024 bit RSA key pair and self-signed certificate (SHA1withRSA) with
a validity of 10,000 days
      for: CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=CN
Enter key password for
      (RETURN if same as keystore password):�Q�alias的密码，如果和keytore密码一��_��直接回�R�Q?nbsp;
Re-enter new password:�Q�确认alias的密码）
[Storing my-release-key.keystore]

2.发布Release版本
Signing in Release Mode

When your application is ready for release to other users, you must:

Obtain a suitable private key
Compile the application in release mode
Sign your application with your private key
Align the final APK package

官方的步骤有4步，�~�译release版本的应用程�?br />
2.1 Eclipse导出
在Eclipse中，右键要发布的��目�Q�依�ơ选择Android Tool -> Export Signed Application Package...
然后��是step-by-step了，选择刚才生成的release版keystore�Q�输入密码，选择alias�Q�输入alias密码�Q�生成release版的apk�?nbsp;

2.2 采用ANT命��o行�Ş�?/strong>

$ ant release

By default, the build script compiles the application APK without signing it. The output file in your project bin/ will be -unsigned.apk. Because the application APK is still unsigned, you must manually sign it with your private key and then align it using zipalign.

默认�~�译出来的版本是没有证书�?em style="color: #006600; font-family: 'courier new', courier, monospace; font-weight: bold; ">-unsigned.apk �Q�需要手动添加证书和寚w��

To specify your keystore and alias, open the project ant.properties file (found in the root of the project directory) and add entries for key.store and key.alias. For example:

我们可以�?strong>ant.properties文�g中指定证书位�|�和寚w��

# This file is used to override default values used by the Ant build system.
#
# This file must be checked into Version Control Systems, as it is
# integral to the build system of your project.

# This file is only used by the Ant script.

# You can use this to override default values such as
#  'source.dir' for the location of your java source folder and
#  'out.dir' for the location of your output folder.

# You can also use it define how the release builds are signed by declaring
# the following properties:
#  'key.store' for the location of your keystore and
#  'key.alias' for the name of the key to use.
# The password will be asked during the build when you use the 'release' target.

#我的证书在上一�U�目录下
#alias是创��书时填写的alias_name

key.store=../keystore_name.keystore
key.alias=alias_name

接下来的步骤很easy�?br />

Save your changes. Now you can build a signed .apk in release mode:

Open a command-line and navigate to the root of your project directory.
Use Ant to compile your project in release mode:
```
ant release
```
When prompted, enter you keystore and alias passwords.
Caution: As described above, your password will be visible on the screen.

This creates your Android application .apk file inside the project bin/ directory, named-release.apk. This .apk file has been signed with the private key specified inant.properties and aligned with zipalign. It's ready for installation and distribution.

ant release后会生成一�?em style="color: #006600; font-family: 'courier new', courier, monospace; font-weight: bold; background-color: #f9f9f9; ">-release.apk的版�?br />
啊，世界清静了~~~

最后就是安装了�?nbsp;
�׃��使用了新的签名，必须先卸载原来安装的�E�序才可以安装�?/span>

/////////////////////////////////////////////////////////////////////////////////////////////////////////////

常见问题�Q?br />生成的debug和release有什么区�?大小差不�?br />
Support for a true debug build. Developers no longer need to add the android:debuggable attribute to the tag in the manifest — the build tools add the attribute automatically. In Eclipse/ADT, all incremental builds are assumed to be debug builds, so the tools insert android:debuggable="true". When exporting a signed release build, the tools do not add the attribute. In Ant, a ant debug command automatically inserts the android:debuggable="true" attribute, while ant release does not. If android:debuggable="true" is manually set, then ant release will actually do a debug build, rather than a release build.
