I have a main class that sets up a blank JFrame, it adds a method from the GUI class I made... that takes 4 arguments, all arraylist… so the first arraylists sent are empty.
Then in my game I made a “guiInstance” that calls the same GUI method.
It is called at the end of each turn.
To update the frame… however I’m having some problems.
It seems that the .update does not like that at all…

So…

“ guiInstance.update(tunnela, tunnelb, player1movement, player2movement); “
I get “cannot find symbol method update” error…

Any suggestions…
Thanks.
