Existing iOS projects embed Cocos2D-X game development

The company’s projects need to be connected to the game business, and cocos2D-X needs to be embedded in existing projects. The articles and materials found on the Internet are quite old, so summarize and record your own embedding process.

Download the cocos2D-x package

Download it at http://www.cocos2d-x.org/download/version#Cocos2d-x

This page has different versions, according to their own needs to download and unzip;

2. Generate iOS projects

1. After decompressing cocos2D-x package, runsetup.pyIs executed on the terminalpython setup.py, there will be two operations that need to enter the path, and return to continue.
2. After the command is executed, execute it againcocosScript:Cocos new < project name, such as: mygame> -p < package name, such as: com.your_company.mygame> -l < development language: lua or CPP or js> -d < project directory, such as: NEW_PROJECTS_DIR>.
3. Finally, one is automatically generated in the current directoryNEW_PROJECTS_DIRFolder, which is generated in this directorymygameThe project.

3. Copy the cocos2D-x resource

1. Existing projects:NewCocosThis project is used for future development

2. CopymygameIn the projectcocos2d-xFiles andClassesThe file toNewCocosThe root directory of the project

In 3.NewCocosCreate one in the root directoryResourcesFolder and willmygameIn the projectres,src,config.jsonCopy toNewCocosIn the projectResourcesFolder.

4. ImportNewCocosproject

1. The importClassesandResourcesresources

2. The importCocos2d_libs. xcodeproj, cocos2d_lua_Bindings. Xcodeproj, libsimulator. Xcodeproj

5. Add the support library

6. Build Settings

1. Close the Bitcode
2. addHeader Search Paths

6. Ending

Because there is an AppDelegate in cocos, to avoid collisions, change the AppDelegate in the project to KMAppDelegate, and in main.m, change the AppDelegate to KMAppDelegate

7. Verify

1. Create a controllerRootViewController

///.h file @interface RootViewController: UIViewController @end ///.mm file#import "RootViewController.h"
#import "cocos2d.h"
#import "platform/ios/CCEAGLView-ios.h"
#include "scripting/lua-bindings/manual/CCLuaEngine.h"
#import "AppDelegate.h"

@interface RootViewController()

@end

    });
}

- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];
    
    delete s_sharedApplication;
    s_sharedApplication = nullptr;

        if (eaglview)
        {
            CGSize s = CGSizeMake([eaglview getWidth], [eaglview getHeight]);
            cocos2d::Application::getInstance()->applicationScreenSizeChanged((int) s.width, (int) s.height);
        }
    }
}

Copy the code

In 2.ViewController.mCreate a button and add a click event

- (IBAction)jump:(id)sender {
    
    RootViewController *vc = [[RootViewController alloc] init];
    [self presentViewController:vc animated:true completion:nil];
}
Copy the code
