## How to run tests

### Cocos Console

You can use [Cocos Console](www.cocos2d-x.org/wiki/Cocos2d-console) command line tool to run the test cases on almost all supported platforms.

In console application:
```
// Enter cpp test folder
cd tests/cpp-tests
// Or enter js test folder
cd tests/js-tests
// Or enter lua test folder
cd tests/lua-tests

// Compile or run test case
cocos compile -p ios|mac|android|win32|win8_1|metro|web -m debug|release
cocos run -p ios|mac|android|win32|win8_1|metro|web -m debug|release
```

For example, if you want to run cpp test in release mode on Android, you can use the following command:

```
cocos run -p android -m release
```

### Mac OSX & iOS

* Enter `cocos2d-x/build` folder, open `cocos2d_test.xcodeproj`
* Select `cpp-tests`, `lua-tests`, `js-tests` for `iOS` or `OS X` target in scheme toolbar
* Click `run` button

### Android

You can run the samples...

**Using command line:**

    $ cd cocos2d-x
    $ ./setup.py
    $ cd build
    $ ./android-build.py cpp-empty-test -p 10
    $ adb install cocos2d-x/tests/cpp-empty-test/proj.android/bin/CppEmptyTest-debug.apk

Then click item on Android device to run tests. Available value of `-p` is the API level, cocos2d-x supports from level 10.

**Using Eclipse:**

    $ cd cocos2d-x
    $ ./setup.py
    $ cd build
    $ ./android-build.py cpp-empty-test -p 10

Then

* Import cocos2d-x Android project into Eclipse, the path used to import is `cocos/2d/platform/android`
* Import `cpp-empty-test` Android project into Eclipse, the path used to import is `tests/cpp-empty-test/proj.android`
* Build `cpp-empty-test` Android project and run

### Windows

* For win32 project, enter `cocos2d-x/build`, and open `cocos2d-win32.sln`
* For win 8.1 project, enter `cocos2d-x/build`, and open `cocos2d-win8.1-universal.sln`
* For win 10 project, enter `cocos2d-x/build`, and open `cocos2d-win10.sln`
* Select running target
* Click run button

### Linux

    $ cd cocos2d-x/build
    $ ./install-deps-linux.sh
    $ cd ../..

Then

    $ mkdir build
    $ cd build
    $ cmake ../cocos2d-x
    $ make -j4

Run

    $ cd bin/cpp-empty-test
    $ ./cpp-empty-test

## How to start a new game

Use Cocos Console to create a new game:

```
cocos new -l cpp|js|lua MyNewGame
```

# v3.10

## Highlights features, improvements and API updates of v3.10

We are happy to announce the release of Cocos2d-x v3.10. Following are the highlighted features, improvements and API updates in this version. 

1. Provides a unified setup for both Cocos2d-x and Cocos.
2. New __Cocos Launcher__ too! __Cocos Launcher__:
  * one step creates a new project by either using our precompiled libraries or
    source code.
  * easily integrate SDKBOX for 3rd party services. Easily add Facebook, in-app
    purchase and many more.
  * provide feedback and get support, directly within __Cocos Launcher__, making
    it simple to contact the engine team for help.
3. UI System:
    - Reimplemented `Scale9Sprite` and improve the scale9sprite performance and reduce memory consumption.
    - Changed `PageView` to derived from ListView, PageView can be added any widget as child.
    - Added three overflow type to new label: **CLAMP**，**SHRINK**，**RESIZE_HEIGHT**.
5. JSModule:
    - Improved JS Bindings: follows [SpiderMonkey](https://developer.mozilla.org/en-US/docs/Mozilla/Projects/SpiderMonkey/GC_Rooting_Guide) GC best practices making it more robust.

## The main features in detail of Cocos2d-x v3.10:

### UI System

1. Reimplemented `Scale9Sprite` and improve the scale9sprite performance and reduce memory consumption.
    
    Reimplemented ui::Scale9Sprite, now the Slice sprite uses 16 vertices and 54 indices instead of the old 9 sprites way, The memory consumption is much lower than the previous implementation, and it is also more efficient.

    In SIMPLE mode, the 4 borders are all 0 and the whole sprite will scale horizontally and vertically. In this mode only 1 quad is used for rendering, for example:

        auto blocks = ui::Scale9Sprite::createWithSpriteFrameName("blocks9c.png");
        //When setting to SIMPLE, only 4 vertexes is used to rendering.
        blocks->setRenderingType(Scale9Sprite::RenderingType::SIMPLE);

    In SLICE mode, it will use 18 triangles to rendering the slice 9 sprite. If the 4 borders are 0, there still be 18 triangles computed. So choose your RenderingType wisely, for example:

		auto sprite = ui::Scale9Sprite::createWithSpriteFrameName("blocks9c.png");
        //When setting to SLICE, 16 vertexes will be used to rendering.
        sprite->setRenderingType(Scale9Sprite::RenderingType::SLICE);
    
2. Changed `PageView` to derived from ListView, PageView can add any type of widget as child.

    PageView was derived from Layout and it implemented the features of scrolling and item arrangement from scratch. But the features are already there in ListView. So remove those duplicated implementations from PageView and make it inherit from ListView.

    By consequence, PageView becomes simpler and easier to maintain because it considers only paging implementation. for example:

        // Create the page view
        Size size(240, 130);
        PageView* pageView = PageView::create();
        pageView->setDirection(PageView::Direction::HORIZONTAL);
        pageView->setContentSize(size);
        Size backgroundSize = background->getContentSize();
        //"removeAllPages" is changed to "removeAllItems"
        pageView->removeAllItems();
        pageView->setIndicatorEnabled(true);

        int pageCount = 4;
        for (int i = 0; i < pageCount; ++i)
        {
            Layout* layout = Layout::create();
            layout->setContentSize(size);
            
            ImageView* imageView = ImageView::create("cocosui/scrollviewbg.png");
            imageView->setScale9Enabled(true);
            imageView->setContentSize(size);
            imageView->setPosition(Vec2(layout->getContentSize().width / 2.0f, layout->getContentSize().height / 2.0f));
            layout->addChild(imageView);
            
            Text* label = Text::create(StringUtils::format("page %d",(i+1)), "fonts/Marker Felt.ttf", 30);
            label->setColor(Color3B(192, 192, 192));
            label->setPosition(Vec2(layout->getContentSize().width / 2.0f, layout->getContentSize().height / 2.0f));
            layout->addChild(label);
            //"insertPage" is changed to "insertCustomItem"
            pageView->insertCustomItem(layout, i);
        }
        //"removePageAtIndex" is changed to "removeItem"
        pageView->removeItem(0);
        //"scrollToPage" is changed to "scrollToItem"
        pageView->scrollToItem(pageCount - 2);

     More detail usage please refer to: tests/cpp-tests/Classes/UITest/CocoStudioGUITest/UIPageViewTest/UIPageViewTest.cpp.
    
   
3. Added three overflow type to new label: CLAMP, SHRINK, RESIZE_HEIGHT.
  
     Overflow type is used to control label overflow result, In SHRINK mode, the font size will change dynamically to adapt the content size. In CLAMP mode, when label content goes out of the bounding box, it will be clipped, In RESIZE_HEIGHT mode, you can only change the width of label and the height is changed automatically. For example:
       
        //Change the label's Overflow type
        label->setOverflow(Label::Overflow::RESIZE_HEIGHT);

     More detail usage please refer to: tests/cpp-tests/Classes/LabelTest/LabelTestNew.cpp.

     Limitations:


     currently only TTF and BMFont support all the valid Overflow type. Char Map font supports all the Overflow type except for SHRINK, because we can't measure its font size. System font only support Overflow::Normal and Overflow::RESIZE_HEIGHT.
