I keep receiving this error, line 77 of Game.java is -


player = new Player(1, 8, ImageIO.read(new File("img/player.png")));

The Player class is in the game package and the image is in the img package (two separate directories).

#2

What does new File(“img/player.png”).exists() return?

Kev

#3

Try adding a “/” before the “img”. This is because you want to start at the root directory, which is the “bin” of Eclipse.

#4

This is incorrect. It will point to the root of your filesystem.

#5

Figured it out, needed to use “src/img/player.png” because my classpath isn’t in the same folder.

#6

Watch over your package too. Src/res folder should be in same place with root folder of package.

#7

Oh right! Using File will cause “/” to point to the root of the file system. Using “/” in System.getResource points to the CWD

#8

Are you thinking of getSystemResoucre() or getResource()? I’m not sure it works like that. I think (I don’t have my computer right now so I can’t check) I use getClass().getClassLoader().getResource(“images/logo.png”); and my file structure in Eclipse is “ProjectFolder -> src -> images -> logo.png” and my source is at “ProjectFolder -> src -> com -> Main.java”. That way when I create a .jar it’s “MyProject.jar -> images -> logo.png”
