Terrain

Troubleshooting General Help

Hi Guys,



I'm using this code to create terrain, but this terrain is randomic.

Is it possible to set a seed to this to create aways the same terrain?


MidPointHeightMap heightMap = new MidPointHeightMap(64, 1f);
      Vector3f terrainScale = new Vector3f(4, 0.0575f, 4);

      terrain = new TerrainBlock("Terrain", heightMap.getSize(), terrainScale, heightMap.getHeightMap(), new Vector3f(0, 0, 0), false);
      terrain.setModelBound(new BoundingBox());
      terrain.updateModelBound();

      ProceduralTextureGenerator pt = new ProceduralTextureGenerator(heightMap);
      pt.addTexture(new ImageIcon(TestTerrain.class.getClassLoader().getResource("jmetest/data/texture/grassb.png")), -128, 0, 128);
      pt.addTexture(new ImageIcon(TestTerrain.class.getClassLoader().getResource("jmetest/data/texture/dirt.jpg")), 0, 128, 255);
      pt.addTexture(new ImageIcon(TestTerrain.class.getClassLoader().getResource("jmetest/data/texture/highest.jpg")), 128, 255, 384);
      pt.createTexture(32);

      TextureState ts = display.getRenderer().createTextureState();
      Texture t1 = TextureManager.loadTexture(pt.getImageIcon().getImage(), Texture.MM_LINEAR_LINEAR, Texture.FM_LINEAR, true);
      ts.setTexture(t1, 0);

      Texture t2 = TextureManager.loadTexture(TestTerrain.class.getClassLoader().getResource("jmetest/data/texture/Detail.jpg"), Texture.MM_LINEAR_LINEAR, Texture.FM_LINEAR);

      ts.setTexture(t2, 1);
      t2.setWrap(Texture.WM_WRAP_S_WRAP_T);

      t1.setApply(Texture.AM_COMBINE);
      t1.setCombineFuncRGB(Texture.ACF_MODULATE);
      t1.setCombineSrc0RGB(Texture.ACS_TEXTURE);
      t1.setCombineOp0RGB(Texture.ACO_SRC_COLOR);
      t1.setCombineSrc1RGB(Texture.ACS_PRIMARY_COLOR);
      t1.setCombineOp1RGB(Texture.ACO_SRC_COLOR);
      t1.setCombineScaleRGB(1.0f);

      t2.setApply(Texture.AM_COMBINE);
      t2.setCombineFuncRGB(Texture.ACF_ADD_SIGNED);
      t2.setCombineSrc0RGB(Texture.ACS_TEXTURE);
      t2.setCombineOp0RGB(Texture.ACO_SRC_COLOR);
      t2.setCombineSrc1RGB(Texture.ACS_PREVIOUS);
      t2.setCombineOp1RGB(Texture.ACO_SRC_COLOR);
      t2.setCombineScaleRGB(1.0f);

      terrain.setRenderState(ts);
      terrain.setDetailTexture(1, 16);
      terrain.setRenderQueueMode(Renderer.QUEUE_OPAQUE);
      scene.attachChild(terrain);

u can export the terrain using binary exporter. that will save the geometry data permenently.



then later on, just use binary importer to load it back in. its also faster this way.

I've solved my own problem:

Use HillHeightMap insted MidPointHeightMap, the first one can recive a seed on his constructor.
