cocos2d-x游戏引擎在每新建一个工程时都会附带好多库文件要编译,导致开发效率降低,一个helloworld项目初次编译可能都要10来分钟。
所以减少编译时间是非常有必要的。 (本文只讲VS2013和Android NDK的方法,其他平台大同小异)
有一个参考 http://blog.csdn.net/etring/article/details/8608032但他的还不够。
我用的是cocos2d-x-3.x 一共有30来个静态库,17个要源码编译,所以做了大量改进更通用一些。
1.新建一个项目HelloCocos2dx: cocos.py new HelloCocos2dx -p com.longshu -l cpp ,有300多M。进入proj.android目录执行ndk-build或者build_native.py。
如果是android-studio,在proj.android-studio\app\jni下执行ndk-build命令。 (建议使用COCOS_ROOT/tests/cpp-empty-test空项目,免去新建项目操作)
2.成功后在proj.android\obj\local\下会默认生成armeabi平台所需要的各种静态库,其他平台在proj.android\jni\Application.mk文件添加即可
比如APP_ABI := armeabi armeabi-v7a x86生成3个平台的静态库。(两个平台第一次编译大概占880M)
3.在COCOS_ROOT(游戏引擎安装目录)下新建一个prebuild文件夹,在prebuild下新建android,android下新建armeabi armeabi-v7a x86(根据自己要的平台),
复制第2步proj.android\obj\local下的相应平台到prebuild下的相应平台目录,一共17个*.a文件(大概210M,libcocos2dcpp.so不要)。复制好后记得 ndk-build clean 。
4.再prebuild/android文件夹下面新建一个Android.mk,内容在文章最后面。该文件是根据COCOS_ROOT/cocos/Android.mk修改而来。
5. 修改proj.android/Android.mk 内容如下:
LOCAL_PATH := $(call my-dir) #Cocos2d-x安装目录,如果环境变量有可以不配 COCOS_ROOT := D:/Dev_Tool/Cocos2d-x include $(CLEAR_VARS) #去除 #$(call import-add-path,$(LOCAL_PATH)/../../cocos2d) #$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external) #$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos) #要添加 不然import-module找不到编译好的静态库 $(call import-add-path,$(COCOS_ROOT)) LOCAL_MODULE := cocos2dcpp_shared LOCAL_MODULE_FILENAME := libcocos2dcpp LOCAL_SRC_FILES := hellocpp/main.cpp \ ../../Classes/AppDelegate.cpp \ ../../Classes/HelloWorldScene.cpp LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes # _COCOS_HEADER_ANDROID_BEGIN # _COCOS_HEADER_ANDROID_END LOCAL_STATIC_LIBRARIES := cocos2dx_static # _COCOS_LIB_ANDROID_BEGIN # _COCOS_LIB_ANDROID_END include $(BUILD_SHARED_LIBRARY) #去除 #$(call import-module,.) # 保存了编译好的静态库目录 $(call import-module,prebuild/android) # _COCOS_LIB_IMPORT_ANDROID_BEGIN # _COCOS_LIB_IMPORT_ANDROID_END
这里新加了两句:
$(call import-add-path,$(COCOS_ROOT))
$(call import-module,prebuild/android)
去除了原来的import-add-path和import-module 。
这样就可以在修改了Classes下的代码和java代码时,在几十秒内完成编译了。以后新建项目只要修改第5步的Android.mk文件就OK了。
而且还可以删除(建议不要,VS或者其他开发工具要用到)cocos2d下的extensions目录和cocos下除platform以外的目录(platform里面还有一个引用项目)。效果如下:
安卓编译效果:
============================================================================================
下面介绍VS2013减少编译时间的方法 和安卓的方法不同
1.打开COCOS_ROOT/build/cocos2d-win32.sln也可以使用上面的HelloCocos2dx,主要是为了方便调试。选择libcocos2d项目,Debug模式,右键->生成,漫长等待后,
在build\Debug.win32目录下会有大量的*.lib和*.dll库文件生成(其实好多是来自Cocos已经编译好的复制过来的),一共有45个文件。
2.在COCOS_ROOT(游戏引擎安装目录)下新建一个prebuild文件夹,在prebuild下新建win32文件夹(最好在下面新建Release和Debug区分编译版本),复制第1步的lib到win32下的Debug和复制dll文件到win32下。
3.修改项目配置: 选择HelloCocos2dx解决方案->右键->属性->通用属性-项目依赖 右边选择HelloCocos2dx项目-去除小面的勾。
选择解决方案下HelloCocos2dx(你的项目)右键->属性->通用属性-引用 移除中间的引用。如下图:
4. 在HelloCocos2dx(你的项目)属性->配置属性->上面选择所有配置->VC++目录 $(Configuration)表示Release和Debug
对于添加 $(COCOS_ROOT)\prebuild\win32和$(COCOS_ROOT)\prebuild\win32\$(Configuration) 如下图:
5.选择HelloCocos2dx(你的项目,不要选择libcocos2d项目了否则又要编译好久),右键-生成-运行 ,是不是飞一般的快呢!?
到这里可以选择libcocos2d项目,右键清理。
存在问题:EXE程序在加载动态库dll文件时会在当期目录和系统path环境变量里找,所以还要把在系统path后面添加 ;%COCOS_ROOT%\prebuild\win32
运行效果:

安卓部分 prebuild/android文件夹下面新建一个Android.mk内容:
