Weird Displayproblem with Textures

Troubleshooting graphics
1

Hi,

My game is almost running, but i when i tried it under Windows XP i got some weird display errors.



So first of all, here is a screenshot what it should look like:





But when i run it under Windows XP (and a friend of mine tried it with his Macbook he got the same errors, but on my macbook everythink is fine) it looks like this:







So, only the textures close to the player are displayed right, the others look kinda weird^^

I don’t even now, where really to look for the error.

So here is the method, how i create the Walls and the Ground:

public static Box createWall(String name,Vector3f pos1,Vector3f pos2,TextureState texState,StandardGame game) {
      // Front Wall
      Box wall = new Box(name,pos1,pos2);
      wall.setModelBound(new BoundingBox());
      wall.updateModelBound();

      CullState culling = game.getDisplay().getRenderer().createCullState();
      culling.setCullFace(CullState.Face.Back);
      wall.setRenderState(culling);
      
      wall.setRenderState(texState);

      return wall;      
   }



And that's how i get the texturestate:

wallTexture = game.getDisplay().getRenderer().createTextureState();
      URL groundLoc;
      groundLoc = Main.class.getClassLoader().getResource("wallTextur.jpg");
      Texture texture = TextureManager.loadTexture(groundLoc, Texture.MinificationFilter.BilinearNearestMipMap , Texture.MagnificationFilter.Bilinear);
      
      texture.setScale(new Vector3f(1.0f,1.0f,1.0f));
      
      wallTexture.setTexture(texture);
      wallTexture.setEnabled(true);



Do you have any idea whats going wrong?

First step, try some of the examples on the problem machines, this rules out hardware drivers requiring updates.

Hi,

I gonna try some other examples later, can't use the computer right now. :frowning:



But i made a small example, which doesn't work on the pc, but works fine on my macbook.

Maybe you can try it:

And as a attachment is the Walls2.xml (with .txt ending, which contains the coords for the walls) and the texture-image.

Maybe you get the same error.

My macbook does not like non-power of 2 images, kinda looks like what your having issues with (my macbook has ATI vcard…)

Hi,

Thanks!

Now it works, after ich changed my pictures so they are a power of 2.



Greets,
