Coordinates terrain

Troubleshooting SDK

Hello ,I’m developed a game,but now I try to do a simple test for the AI of character( just move it ), so I wonder:

If I 've the algorithm logic of minimal path, how to know the coordinates of terrain for set the position character for every step ? Or in general for position an object in a point of the scene?

[java]
private void createTerrain() {
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) {
    }

    terrain = new TerrainQuad("terrain", 65, 513, heightmap.getHeightMap());

    terrain.setLocalScale(new Vector3f(2, 2, 2));
    terrainPhysicsNode = new RigidBodyControl(CollisionShapeFactory.createMeshShape(terrain), 0);
    terrain.addControl(terrainPhysicsNode);
    rootNode.attachChild(terrain);
    getPhysicsSpace().add(terrainPhysicsNode);
}

[/java]

Picking

Can you be more clearly ?

You get the coordinates of a point on the terrain by picking.
