That's hilarious, I removed that in my code when I figured out the problem, I never even realized how backwards that was. Oh the joys of small changes causing big problems.

Jar doesn't find file

By Lakorta, with no replies.

Hi, I have a little problem with the .jar file from my Greenfoot project. I load a file (map.dat) with "BufferedReader br = new BufferedReader(new FileReader("data/map.dat"));". It works really fine, until I compile my project to a .jar file. Then it couldn't find the map.dat. If I use the complete path /home/lakorta/greenfoot/scenarios/game/data/map.dat (Windows: C:\...\Greenfoot\scenarios\game\data\map.dat) he could load it. Please help!

Line 41 is the wrong line like nccb just said, but your variable x is from type boolean, so you also can write if (x) { ... }. It is the same effect, this one is just shorter.
