 1 | cocos2d-x-panzoomlayer
 2 | ======================
 3 | 
 4 | You can use panning and zooming with inheriting this class!
 5 | 
 6 | 
 7 | *Usage Example:*
 8 | 
 9 | ```
10 |   auto map = Sprite::create("map.jpg");
11 |   auto mapSize = map->getContentSize();
12 |   map->setAnchorPoint(Vec2(0, 0));
13 |   map->setPosition(mapSize * -0.5f);
14 |   PanZoomLayer *pzLayer = PanZoomLayer::create();
15 |   this->addChild(pzLayer);
16 |   pzLayer->SetPanBoundsRect(Rect(mapSize.width * -0.5f, mapSize.height * -0.5f, mapSize.width * 1.0f, mapSize.height * 1.0f));
17 |   pzLayer->setScale(1.0f);
18 |   pzLayer->addChild(map);
19 | ```

/proj.android/README.md:
--------------------------------------------------------------------------------
 1 | ## Prerequisites:
 2 | 
 3 | * Android NDK
 4 | * Android SDK **OR** Eclipse ADT Bundle
 5 | * Android AVD target installed
 6 | 
 7 | ## Building project
 8 | 
 9 | There are two ways of building Android projects.
10 | 
11 | 1. Eclipse
12 | 2. Command Line
13 | 
14 | ### Import Project in Eclipse
15 | 
16 | #### Features:
17 | 
18 | 1. Complete workflow from Eclipse, including:
19 | 	* Build C++.
20 | 	* Clean C++.
21 | 	* Build and Run whole project.
22 | 	* Logcat view.
23 | 	* Debug Java code.
24 | 	* Javascript editor.
25 | 	* Project management.
26 | 2. True C++ editing, including:
27 | 	* Code completion. 
28 | 	* Jump to definition.
29 | 	* Refactoring tools etc. 
30 | 	* Quick open C++ files.
31 | 
32 | 
33 | #### Setup Eclipse Environment (only once)
34 | 
35 | 
36 | **NOTE:** This step needs to be done only once to setup the Eclipse environment for cocos2d-x projects. Skip this section if you've done this before.
37 | 
38 | 1. Download Eclipse ADT bundle from [Google ADT homepage](http://developer.android.com/sdk/index.html)
39 | 
40 |    **OR**
41 | 
42 |    Install Eclipse with Java. Add ADT and CDT plugins.
43 | 
44 | 2. Only for Windows
45 |     1. Install [Cygwin](http://www.cygwin.com/) with make (select make package from the list during the install).
46 |     2. Add `Cygwin\bin` directory to system PATH variable.
47 |     3. Add this line `none /cygdrive cygdrive binary,noacl,posix=0,user 0 0` to `Cygwin\etc\fstab` file.
48 |    
49 | 3. Set up Variables: 
50 | 	1. Path Variable `COCOS2DX`: 
51 | 		* Eclipse->Preferences->General->Workspace->**Linked Resources**
52 | 		* Click **New** button to add a Path Variable `COCOS2DX` pointing to the root cocos2d-x directory.
53 | 		![Example](https://lh5.googleusercontent.com/-oPpk9kg3e5w/UUOYlq8n7aI/AAAAAAAAsdQ/zLA4eghBH9U/s400/cocos2d-x-eclipse-vars.png)
54 | 
55 | 	2. C/C++ Environment Variable `NDK_ROOT`: 
56 | 		* Eclipse->Preferences->C/C++->Build->**Environment**.
57 | 		* Click **Add** button and add a new variable `NDK_ROOT` pointing to the root NDK directory.
58 | 		![Example](https://lh3.googleusercontent.com/-AVcY8IAT0_g/UUOYltoRobI/AAAAAAAAsdM/22D2J9u3sig/s400/cocos2d-x-eclipse-ndk.png)
59 | 		* Only for Windows: Add new variables **CYGWIN** with value `nodosfilewarning` and **SHELLOPTS** with value `igncr`
60 | 		
61 | 4. Import libcocos2dx library project:
62 | 	1. File->New->Project->Android Project From Existing Code.
63 | 	2. Click **Browse** button and open `cocos2d-x/cocos2dx/platform/android/java` directory.
64 | 	3. Click **Finish** to add project.
65 | 	
66 | #### Adding and running from Eclipse
67 | 
68 | ![Example](https://lh3.googleusercontent.com/-SLBOu6e3QbE/UUOcOXYaGqI/AAAAAAAAsdo/tYBY2SylOSM/s288/cocos2d-x-eclipse-project-from-code.png) ![Import](https://lh5.googleusercontent.com/-XzC9Pn65USc/UUOcOTAwizI/AAAAAAAAsdk/4b6YM-oim9Y/s400/cocos2d-x-eclipse-import-project.png)
69 | 
70 | 1. File->New->Project->Android Project From Existing Code
71 | 2. **Browse** to your project directory. eg: `cocos2d-x/cocos2dx/samples/Cpp/TestCpp/proj.android/`
72 | 3. Add the project 
73 | 4. Click **Run** or **Debug** to compile C++ followed by Java and to run on connected device or emulator.
74 | 
75 | 
76 | ### Running project from Command Line
77 | 
78 |     $ cd cocos2d-x/samples/Cpp/TestCpp/proj.android/
79 |     $ export NDK_ROOT=/path/to/ndk
80 |     $ ./build_native.sh
81 |     $ ant debug install
82 | 
83 | If the last command results in sdk.dir missing error then do: 
84 | 
85 |     $ android list target
86 |     $ android update project -p . -t (id from step 6)
87 |     $ android update project -p cocos2d-x/cocos2dx/platform/android/java/ -t (id from step 6)
88 |

15 |              The name of the source directory. Default is 'src'.
16 |          out.dir
17 |              The name of the output directory. Default is 'bin'.
18 | 
19 |          For other overridable properties, look at the beginning of the rules
20 |          files in the SDK, at tools/ant/build.xml
21 | 
22 |          Properties related to the SDK location or the project target should
23 |          be updated using the 'android' tool with the 'update' action.
24 | 
25 |          This file is an integral part of the build system for your

67 |                <import> task.
68 |              - customize it to your needs.
69 |          - Customize the whole content of build.xml
70 |              - copy/paste the content of the rules files (minus the top node)
71 |                into this file, replacing the <import> task.
72 |              - customize to your needs.

75 |          ****** IMPORTANT ******

77 |          In all cases you must update the value of version-tag below to read 'custom' instead of an integer,
78 |          in order to avoid having your file be overridden by tools such as "android update project"
