Hi, I try to modify a picking Test with a terrain , but it doesn’t work and I don’t understand why?
this is the essential code :
[java]
private void initTerrain(){
matRock = new Material(assetManager, "Common/MatDefs/Terrain/TerrainLighting.j3md");
Texture heightMapImage = assetManager.loadTexture("Textures/Terrain/splat/road_normal.png");
AbstractHeightMap heightmap = null;
try {
heightmap = new ImageBasedHeightMap(heightMapImage.getImage(), 0.25f);
heightmap.load();
} catch (Exception e) {
e.printStackTrace();
}
terrain = new TerrainQuad("terrain", 65, 513, heightmap.getHeightMap());
List<Camera> cameras = new ArrayList<Camera>();
cameras.add(getCamera());
TerrainLodControl control = new TerrainLodControl(terrain, cameras);
terrain.addControl(control);
terrain.setMaterial(matRock);
terrain.setLocalScale(new Vector3f(2, 2, 2));
terrainPhysicsNode = new RigidBodyControl(CollisionShapeFactory.createMeshShape(terrain), 0);
terrain.addControl(terrainPhysicsNode);
rootNode.attachChild(terrain);
getPhysicsSpace().add(terrainPhysicsNode);
}
public void initShootable(){
shootables= new Node("shootables");
shootables.attachChild(terrain);
}
/** Defining the "Shoot" action: Determine what was hit and how to respond. */
private ActionListener actionListener = new ActionListener() {
public void onAction(String name, boolean keyPressed, float tpf) {
if (name.equals("Picking") && !keyPressed) {
// 1. Reset results list.
CollisionResults results = new CollisionResults();
// 2. Aim the ray from cam loc to cam direction.
Ray ray = new Ray(cam.getLocation(), cam.getDirection());
// 3. Collect intersections between Ray and Shootables in results list.
shootables.collideWith(ray, results);
// 4. Print the results
System.out.println("----- Collisions? " + results.size() + "-----");
/*
for (int i = 0; i < results.size(); i++) {
// For each hit, we know distance, impact point, name of geometry.
float dist = results.getCollision(i).getDistance();
Vector3f pt = results.getCollision(i).getContactPoint();
String hit = results.getCollision(i).getGeometry().getName();
System.out.println("* Collision #" + i);
System.out.println(" You shot " + hit + " at " + pt + ", " + dist + " wu away.");
}
// 5. Use the results (we mark the hit object)
if (results.size() > 0) {
// The closest collision point is what was truly hit:
CollisionResult closest = results.getClosestCollision();
// Let's interact - we mark the hit with a red dot.
mark.setLocalTranslation(closest.getContactPoint());
rootNode.attachChild(mark);
} else{
// No hits? Then remove the red mark.
rootNode.detachChild(mark);
}
*/
}
}
};
[/java]
Maybe there is my distraction or there is something that I have not considered
