macOS Running jar file via .command file

[JavaWizKid]

How can I do this?

#!/bin/bash
java -jar -Djava.library.path=lib CastleWars.jar

It errors with unable to access CastleWars.jar

How can I get unix to recognise where the .command file is being launched from and then put that path in front of CastleWars.jar?

GOT IT!
#!/bin/bash
java -jar -Djava.library.path="$_/../"lib "$_/../"CastleWars.jar

#!/bin/bash
java -jar -Djava.library.path="$_/../"lib "$_/../"CastleWars.jar

Shouldn't it be?:

java  -Djava.library.path=lib  -jar CastleWars.jar
