Draw problem upon compile[SOLVED]

Newbie & Debugging Questions
#1

Ok, so I am having trouble with my Play menu, when I run my program under eclipse the layers get drawn in, however when I run it under its own executable they do not. Can someone take a look at my code.

Here is my source zipped up source

Also if you do not want to download anything I would be happy to let you connect directly to my project and take a look at it.

The problem was solved! It was a problem of calling an outside resource and not an inside

Have you run the jar from the command line? 99% of these situations are caused by errors that will show up in the command line.

Also, just so you know: Eclipse complies your code whenever you run it inside Eclipse, so this isn’t a “post-compilation” problem, it’s a “post-export” problem.

#3

I have, and it did the same thing. I see, well something is going on here xD I just can not figure out what.

It does draw the player though, It is almost like it is just not reading the map files.

#4

Throw in some print lines when you load the maps in. Run it from the command line and see if everything works out ok.

#5

It works perfectly fin when I run it straight from eclipse, it just does this when It is ran as an independent jar file.

#6

I know. That’s why I said to print out what’s happening so you can see if it works when exported.

#7

Well if loads the ground.draw, perfectly fine during bother I used
g.setColor(Color.YELLOW);
g.drawString(“Map loaded”, 50,50);

and Map loaded shows when It is ran as an independent and when I run it through eclipse. So it is having trouble loading the grounds mapfile.

#8

I see in your code you’re using FileReaders. That won’t work on files that are packaged inside a jar file.
Solution to that is to either:

  • Not have the files packed in the jar, but instead alongside the jar.
  • Use Class.getResourceAsStream()

Look up those if you don’t know what I’m talking about.

#9

I could help more, but I would rather not download your entire project. Could you post the relevant code?

#10

It works! YAY xD thank you very much sir. I will look up Class.getResourceAsStream() because I do want the map files packed into my jar.
@opiop65. Thank you for attempting to help as well. All of the help is much appreciated!
