I have started to learn game development using jMonkey engine. I am able to create single tile of terrain using TerrainQuad but as the next step I'm stuck at making it infinite. I have gone through the wiki and want to use the TerrainGrid class but my code does not seem to work. I have looked around on the web and searched other forums but cannot find any other code example to help. I believe in the below code, ImageTileLoader returns an image which is the heightmap for that tile. I have modified it to return the same image every time. But all I see is a black window. The Namer method is not even called. terrain = new TerrainGrid("terrain", patchSize, 513, new ImageTileLoader(assetManager, new Namer() { public String getName(int x, int y) { //return "Scenes/TerrainMountains/terrain_" + x + "_" + y + ".png"; System.out.println("X = " + x + ", Y = " + y); return "Textures/heightmap.png"; } })); These are my sources: jMonkeyEngine 3 Tutorial (10) - Hello Terrain TerrainGridTest.java ImageTileLoader This is the result when i use TerrainQuad: , My full code: // Sample 10 - How to create fast-rendering terrains from heightmaps, and how to // use texture splatting to make the terrain look good. public class HelloTerrain extends SimpleApplication { private TerrainQuad terrain; Material mat_terrain; private float grassScale = 64; private float dirtScale = 32; private float rockScale = 64; public static void main(String[] args) { HelloTerrain app = new HelloTerrain(); app.start(); } private FractalSum base; private PerturbFilter perturb; private OptimizedErode therm; private SmoothFilter smooth; private IterativeFilter iterate; @Override public void simpleInitApp() { flyCam.setMoveSpeed(200); initMaterial(); AbstractHeightMap heightmap = null; Texture heightMapImage = assetManager.loadTexture("Textures/heightmap.png"); heightmap = new ImageBasedHeightMap(heightMapImage.getImage()); heightmap.load(); int patchSize = 65; //terrain = new TerrainQuad("my terrain", patchSize, 513, heightmap.getHeightMap()); // * This Works but below doesnt work* terrain = new TerrainGrid("terrain", patchSize, 513, new ImageTileLoader(assetManager, new Namer() { public String getName(int x, int y) { //return "Scenes/TerrainMountains/terrain_" + x + "_" + y + ".png"; System.out.println("X = " + x + ", Y = " + y); return "Textures/heightmap.png"; // set to return the sme hieghtmap image. } })); terrain.setMaterial(mat_terrain); terrain.setLocalTranslation(0,-100, 0); terrain.setLocalScale(2f, 1f, 2f); rootNode.attachChild(terrain); TerrainLodControl control = new TerrainLodControl(terrain, getCamera()); terrain.addControl(control); } public void initMaterial() { // TERRAIN TEXTURE material this.mat_terrain = new Material(this.assetManager, "Common/MatDefs/Terrain/HeightBasedTerrain.j3md"); // GRASS texture Texture grass = this.assetManager.loadTexture("Textures/white.png"); grass.setWrap(WrapMode.Repeat); this.mat_terrain.setTexture("region1ColorMap", grass); this.mat_terrain.setVector3("region1", new Vector3f(-10, 0, this.grassScale)); // DIRT texture Texture dirt = this.assetManager.loadTexture("Textures/white.png"); dirt.setWrap(WrapMode.Repeat); this.mat_terrain.setTexture("region2ColorMap", dirt); this.mat_terrain.setVector3("region2", new Vector3f(0, 900, this.dirtScale)); Texture building = this.assetManager.loadTexture("Textures/building.png"); building.setWrap(WrapMode.Repeat); this.mat_terrain.setTexture("slopeColorMap", building); this.mat_terrain.setFloat("slopeTileFactor", 32); this.mat_terrain.setFloat("terrainSize", 513); } }
