Paint texture on a terrain [solved]

Troubleshooting graphics
1

Hi,

I want to do a 3D remake of the game AdvanceWars, see here: http://img.brothersoft.com/screenshots/softimage/a/advance_wars_2_-_black_hole_rising-171684-1.jpeg



So I want to create a terrain, wich is divided into (invisible) squares. If the player wants to move a tank, then the reachable squares should be highlighted. To visualise this, I basically need to add a texture for a highlighted square and then paint this texture for each reachable square on the texture of the terrain. How can I do that?



Thanks in advance!

Ok, after 6 hours of trying I figured it out myself  :wink:



Here is the code if somebody needs it:



      Box b = new Box("Box", new Vector3f(), 100, 100, 100);
      b.setLocalTranslation(new Vector3f(0, 0, -500));
      b.setModelBound(new BoundingBox());
      b.updateModelBound();

      // CREATE TEXTURESTATE
      ts = display.getRenderer().createTextureState();
      ts.setEnabled(true);
      // LOAD AND SET FIRST TEXTURE
      Texture t1 = TextureManager.loadTexture(Test.class.getClassLoader()
            .getResource("jmetest/data/images/Monkey.jpg"),
            Texture.MinificationFilter.BilinearNearestMipMap,
            Texture.MagnificationFilter.Bilinear);
      ts.setTexture(t1, 0);

      // LOAD AND SET SECOND TEXTURE
      Texture t2 = TextureManager.loadTexture(Test.class.getClassLoader()
            .getResource("jmetest/data/texture/dirt.jpg"),
            Texture.MinificationFilter.BilinearNearestMipMap,
            Texture.MagnificationFilter.Bilinear);
      ts.setTexture(t2, 1);

      t2.setWrap(WrapMode.BorderClamp);
      t2.setTranslation(new Vector3f(-0.0f, -3.0f, 0.0f));

      t2.setApply(Texture.ApplyMode.Blend);

      // IMPORTANT:
      b.copyTextureCoordinates(0, 1, 5.0f);
      b.setRenderState(ts);

      b.setRenderQueueMode(Renderer.QUEUE_OPAQUE);
      scene.attachChild(b);



The trick was to call b.copyTextureCoordinates(0, 1, 5.0f), wich scales the second texture. If you want to have for example 5 * 5 squares, the third parameter has to be set to 5.0f. Then you can move the square with t2.setTranslation(new Vector3f(-1.0f, -3.0f, 0.0f)) to it's desired position on the playfield.

Would this work to paint roads onto a 3d Terrain?

Given the age of this thread, that code won’t even work in JME3.
