How to create multiplatform Cocos2d-x-JSB project with CocosBuilder, Eclipse ADT and XCode on Mac?

In this tutorial I’ll show you how to create Cocos2d-x-JSB (ver. 2.2.6) project which you will be able to run both on Android and iOS devices.

0. Prerequisites (you will need):

1. Creating new project:

> cd DEV/cocos2d-x-2.2.6/tools/project-creator/
> ./create_project.py -project FindOut -package com.GalanteLabs.FindOut -language javascript
proj.ios                : Done!
proj.android            : Done!
proj.win32              : Done!
New project has been created in this path: /Users/tobiasz/DEV/cocos2d-x-2.2.6/projects/FindOut
Have Fun!
> cd ../../projects/FindOut/
> rm -rf Resources/

2. New CocosBuilder project:

  • File > New > Project
  • go to the “projects” folder in your COCOS2DX_HOME location
  • enter the same project name as before
  • click Save and next Replace

3. CocosBuilder project configuration:

  • firstly create 4 folders in Resources dir in our project: interface, images, js, sounds
  • File > Project Settings
  • remove Resources dir from list
  • add 4 created folders in this order: interface, js, images, sounds
  • Done

4. CocosBuilder publishing configuration:

  • File > Publish settings
  • in iOS section unmark iPad
  • mark section Android and next medium field
  • unmark section HTML5
  • Done

5. AppDelegate.cpp configuration:

  • modify AppDelegate.cpp file located in Classes folder:
#include "AppDelegate.h"

#include "cocos2d.h"
#include "SimpleAudioEngine.h"
#include "ScriptingCore.h"
#include "generated/jsb_cocos2dx_auto.hpp"
#include "generated/jsb_cocos2dx_extension_auto.hpp"
#include "jsb_cocos2dx_extension_manual.h"
#include "cocos2d_specifics.hpp"
#include "js_bindings_chipmunk_registration.h"
#include "js_bindings_system_registration.h"
#include "js_bindings_ccbreader.h"
#include "jsb_opengl_registration.h"
#include "XMLHTTPRequest.h"
#include "jsb_websocket.h"

6. Publishing our project with CocosBuilder:

  • Come back to CocosBuilder and press File > Publish

7. Android (Eclipse ADT):

  • File > Import > Android > Existing Android Code Into Workspace > Next
  • Browse > select COCOS2DX_HOME location
  • Select created project and libcocos2dx project > Finish
  • Expand your project in project explorer view and 2x click on “build_native.sh” to edit it
  • Add path to Android NDK in second line in file:
NDK_ROOT="/Users/tobiasz/DEV/android/android-ndk-r8e"

and line:

cp -rf "$APP_ROOT"/Resources/* "$APP_ANDROID_ROOT"/assets

replace with:

cp -rf "$APP_ROOT"/Published-Android/* "$APP_ANDROID_ROOT"/assets
  • Next connect Android device to your Mac and click on your project > Run as > Android Application. Build and run. First compilation may take from 5 to 10 minutes so be patient :)

8. iOS (XCode):

  • open project proj.ios/FindOut.xcodeproj with XCode
  • remove unused references from Resources dir

4

  • drag Published-iOS dir from your CocosBuilder project location to this XCode project. Select option “Create folder references…”

5

  • it should look like this:

6

  • Build and run! :)

Finished! Now you can continue developing your first own game with Cocos2dx :)
