Realm of the Automated God is a Bot that plays Realm of the Mad God.
Unfortunately, t's really janky and I'm certain that you won't be able to get it to work on your machine without many hours of work. This is because it was made for the purpose of tinkering with and showing the worth of the Robot.java library, and that task is a success
Run Runner with java
Within five seconds, place your mouse pointer at the top left of the main gameplay square of Realm of the Mad God. The program will report to stdout when it has confirmed the top left coordinate. Then within three seconds, place the mouse pointer at the bottom right of the main gameplay square. The bot will confirm the bottom right coordinate and take control of the mouse/keyboard.
One can extend UserCharacter.java to create a different bot. MadGod.java handles the scanning of game data from your screen and Runner passes it to UserCharacter.
