Tests

There are some built in tests for the game engine that can be found in the Tests folder. To run the test just double click the .jar file.

Or open a terminal and type java -jar TestFile.jar

The window size can be configured using the window640x480 argument.

The render resolution can be set as a percentage of the window size using the render75 argument.
