Not running after export from eclipse?

Newbie & Debugging Questions
#1

Hi,
I have made a game and it works just fine in eclipse but when i export it to a runnable jar it wont run(well it will “run” but nothing will happen, it wont render any thing). Also how would i make a main menu for my game. Please help.

Thanks,
Drok

What happens when you run the jar via the command prompt? Do you see any exceptions?

What have you tried to create a main menu?

Hi,
There dont seem to be any exceptions when i run it in the command prompt and i dont have any thing for the main menu yet because i dont know when to start.

#4

The menu is a separate issue. Can you post an MCVE that demonstrates the same problem?

#5

I sadly cannot due to the fact that this is the first time i tested it outside eclipse but i can supply the code i have if you wish.

Here is the MCVE:
