A remake of a game I started when I was in college. I lost all of my files from that time, and because of that I completely forget the idea of finishing it. But I want to finish this one, so I start again from sratch and gonna build everything better that I did before. Gonna take some time though.

First, you have to compile all the file of src to the run directory :

javac -classpath ./src/ -d ./run/ ./src/*/*.java

Then, you have to create the jar. So we have to run this command :

cp -r src/assets/ run/ && cd run && jar -cvfm test.jar META-INF/MANIFEST.MF *

Finally, you can run the jar for testing of everything is OK :

java -jar test.jar && chmod +x test.jar

?

When trying to run the jar executable :

The file '/home/rumarocket/eclipse-workspace-java/Cat01/run/test.jar' is not marked as executable.  If this was downloaded or copied from an untrusted source, it may be dangerous to run.  For more details, read about the executable bit.

Simply means that the file is not an executable, so you have to setting the property of the file as an excutable file.
