Cocos Creator集成到原生swift

一、集成流程

1. 下载Creator2.4.10版本

官网地址： https://www.cocos.com/creator-download

2. 新建cocos-HelloWorld项目

image.png

3. 顶部工具栏->项目->构建发布

按如下配置，构建、编译、运行iOS工程

image.png

构建时勾选default，不是link
jsb-default文件夹下的内容就是我们iOS开发需要的代码了

4. 运行jsb-default下的iOS工程

这一步的作用是为了验证构建的工程是没有问题的,同时获取到我们这个工程集成到iOS需要的配置是哪些

image.png

得到一个能够正常运行的工程非常重要!
后续集成Cocos Creator就是将此demo工程的相关代码、配置挪到自己的iOS工程。

5. 整理引擎代码

在工程目录下创建 cocos 文件夹, 然后找到之前游戏构建的代码,复制到cocos文件夹下,这里的jsb-default就是cocos项目构建成功后的代码:

image.png

注:

• 红框内容是Cocos游戏代码，迁移至/Resource文件夹，若替换游戏直接替换/Resource内所有内容
• frameworks中,可以只导入frameworks-->runtime-src-->proj.ios_mac + Classes , proj.android-studio和proj.win32 可以不导入

6. 导入游戏引擎到自己的工程

image.png

• 以Create groups方式** **添加 Classes、ios
• 以Create groups whith folder方式 添加 Resources内部文件，注意 /Resource 一定不能是folder方式（灰色）
• 以Create groups方式** **添加cocos2d_libs.xcodeproj，注意不需要将cocos2d-x文件夹拖入工程

7. 工程中移除ios文件夹下的main.m、Info.plist

否则与主工程文件冲突

8. 导入项目的依赖库

具体以第2步构建导出的Demo工程为准

image.png

9. 导入libcocos2d iOS(cocos2d_libs)

为原生iOS工程的TARGETS添加Dependences(Build Phase/Dependencies)：libcocos2d iOS(cocos2d_libs),有两处都要添加

image.png

注:如果删除了cocos2d-x下的文件夹,重新导入了,可能会导致 libcocos2d iOS丢失,需要再次按照上面的流程重新导入一次,不然报错: cocos的一些方法找不到了

10. 配置工程头文件搜索路径

若编译时报错头文件找不到，则在此处添加路径

image.png

• Library Search Paths 添加 $(SRCROOT)/cocos/frameworks/cocos2d-x/external/iOS/libs
• User Header Search Paths 添加如下：（具体需参考第2步构建导出的Demo工程）

$(PROJECT_DIR)/cocos/frameworks/cocos2d-x
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/base
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/2d
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/ui
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/network
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/audio/include
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/editor-support
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/extensions
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/external
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/external/sources
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/external/chipmunk/include/chipmunk
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/scripting/js-bindings/auto
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/cocos/scripting/js-bindings/manual
$(PROJECT_DIR)/cocos/frameworks/cocos2d-x/external/mac/include/v8

11. 其他配置

• 为TARGETS为other linker flags 添加 -Objc
• 把PROJECT和TARGETS的Enable BitCode都设为NO
• 在PROJECT和TARGETS为Preprocessor Macros添加预定义宏，具体需参考第2步构建导出的Demo工程

image.png

12. 工程代码的修改

• 修改Classes文件夹下的AppDelegate.h 和 AppDelegate.cpp
  把名称改成CocosAppDelegate.h 和 CocosAppDelegate.cpp,把代码内的AppDelegate全部替换成CocosAppDelegate
• 修改 目录: cocos2d_libs -> platform -> iOS下的 CCApplication-ios.mm 文件的end方法

void Application::end()
{
    //    delete this;
       //
       //    exit(0);
       
       // 上面是原来的样子
   #if USE_AUDIO
       AudioEngine::end();
   #endif
       // stop main loop
       [(MainLoop*)_delegate stopMainLoop];
 
}

修改它的目的是为了cocos引擎在启动后,退出游戏不自动关闭引擎,不杀死APP,再次进入游戏,可以直接开始游戏，切换另一个游戏。

13. 创建游戏引擎管理类

image.png

• CocosManager：控制游戏开始结束等

//
//  CocosManager.h
//
//  cocos引擎管理器，负责iOS启动、退出以及管理cocos引擎
/*
 
 类名不要改变,对应cocos的JS调用OC的类名;
 所有的供JS调用的方法,使用类方法;
 所有的OC调用的JS方法,统一写在CocosManager下;

注：

• 特别注意两个文件是OC、C++混编，.mm后缀
• 在Compile Sources必须保证有这三个文件

14. 创建桥接文件

• 新建 Swift-Bridge-Objective-C.h

//
//  Swift-Bridge-Objective-C.h
//  FlatGame
//
//

#ifndef Swift_Bridge_Objective_C_h
#define Swift_Bridge_Objective_C_h

#import "CocosManager.h"
#import "GameViewController.h"

#endif /* Swift_Bridge_Objective_C_h */

• XCode配置桥接文件路径

二、问题汇总

1. python版本问题，必须使用python2.x版本

2. 子工程编译问题

image.png
严格参照第2步构建导出的Demo工程，打开里面的 cocos2d_libs.xcodeproj，保证内部文件个数、路径都一致（部分不需要的则删除，具体看Demo工程里是否引入了），保证子工程编译通过，再拖进自己工程。

• 注意只需要拖入 cocos2d_libs.xcodeproj，不需要将 cocos2d-x文件夹拖入工程

3. Undefined symbol：头文件找不到错误总结

image.png

• 红色：系统库头文件找不到，回到 【8. 导入项目的依赖库】检查缺失
• 蓝色：cocos引擎头文件找不到，回到【10. 配置工程头文件搜索路径】检查添加路径

4. Undefined symbol: OBJC_CLASS$_CocosManager （类找不到）

回到【13. 创建游戏引擎管理类】检查 Compile Sources是否添加 CocosManager.mm
还不行回到【14. 创建桥接文件】检查桥接文件
