CrossPlatformModule

A Demo showing how to create a cross platform game on Android & Desktop using JMonkeyEngine.
Note : The project uses gradle 6.7.1, to support java-8 on android studio 4.2.0, you can upgrade to gradle-7.2.1 and use AGP-7 as you like.

Modules :

1. Game module :game : holds build.gradle dependencies for the game code & should hold your code.

2. Desktop module :desktop : holds build.gradle for desktop dependencies & implements the :game module, this module can hold the desktop gui.

3. Android module :app : holds build.gradle for the android dependencies & implements the :game module, this module can hold android dependent gui.

Features :

1. Gradle.

2. A single assets res folder (gradle resource folder).

3. Android Support via :app module.

4. Desktop Support via :desktop module.

5. Jar building task & app assembly.

Running Game :

Desktop :

./gradlew run

Android :

Install the app on a connected device via adb.
