Besides the obvious changes in rendering and input code there is four new types introduced that in the original code are represented either as an
To test it out download the repository and build it using gradle.
- JDK - http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
- Gradle - http://www.gradle.org/
The following instructions assumes you are in the root folder of the project, eg.
$ git clone https://github.com/walle/raycaster.git $ cd raycaster
The first time you build the project is going to take a while since all dependencies are downloaded, will be faster after that.
Building the desktop version
The easiest way to test the project is on desktop, just run
$ ./gradlew desktop:run
Building the Android version
Make sure you have the Android SDK and have created an AVD. http://developer.android.com/sdk/index.html#download Start the emulator with your AVD and have it running before building the project. Eg.
$ cd /path/to/android/sdk $ tools/emulator -avd my_avd_name -gpu on
When you see the emulated home screen, run the gradle task
$ ./gradlew android:installDebug android:run
Building the web version
$ ./gradlew html:superDev
Then open your browser to http://localhost:8080/html/
Building the IOS version
To build the IOS version it's required to use OS X. Also to have Xcode installed, install it from the AppStore.
When you have Xcode installed, make sure you have the iOS Simulator installed, otherwise install it.
Xcode -> Preferences -> Downloads
Then run the gradle task to start the simulator.
$ ./gradlew ios:assemble launchIPhoneSimulator
