Hello,
i use LWJGL(opengl) and i learn from this tutorial:http://www.youtube.com/watch?v=7G_xtkvyleM
from the beginning everything worked just fine until now:(
i dont know why every time i play this mini game(mine craft 2d) , the window is black and everything get stuck.
why is that happening ?
is that a problem with my processor(intel coreTM 2) ?
or maybe its the display adapters(NVIDIA GeForce 9500 GT)?
help please ! ty.
and if you wanna see my code just ask.

Yes, we would like to see your code. It's kind of hard to diagnose a disease over a phone when you're told the symptom of the patient is "something is wrong"... Wink

From what you did tell us however, I'd say that this is most likely not a hardware problem.

Also, if you really want an answer quickly I recommend that you create at least one thread in each sub-forum on JGO. The sub-forum topics are just recommendation, so if you're really important anything goes. Also consider spamming private messages to Riven (our glorious leader) and pretty much anyone else if your problem is REALLY urgent.

For starters...

Change this:

1
2
3
4
5
6
7
8
9
10

   public void draw()
   {
      for(int i=0 ; i<BLOCKS_WIDTH - 1 ; i++)
      {
         for(int j=0 ; j<BLOCKS_HEIGHT - 1 ; j++)
         {
            ...
         }
      }
   }

To this:

1
2
3
4
5
6
7
8
9
10

   public void draw()
   {
      for(int i=0 ; i<BLOCKS_WIDTH; i++)
      {
         for(int j=0 ; j<BLOCKS_HEIGHT; j++)
         {
            ...
         }
      }
   }

I have been wanting a similar article to show to my friend for ages! I was really close to finally writing something similar Tongue

Thank you!

@OP
Rarely will anyone look through all your code and figure out what the problem is. You should at least have some sense of where the bug might occur, but just dumping it all on us will not help you very much :/
