This is a template game, that pulls in the base game as a dependency. This makes it easier for us to change the base game without upsetting your code as much
Change the classes "Game" and "GameEditor" to your "GameName" and "GameNameEditor"
Open the pom.xml and change the groupId from "com.fossgalaxy.game" to "com.fossgalaxy.GameName" as well as altering the artifactId and the name
Also change the game.json file, the other json files to something game specific and the reference to game.json in Game.java and GameEditor.java
It is best to start developing with the map editor, and then you can move to testing the game itself.
Games must have a valid map file to run
