Blue cube

Troubleshooting SDK
1

I’m completely new to jMonkeyEngine



I tried to run my first program via jMonkeyEngine SDK 3.0RC2 (on Ubuntu) the first time but Blue cube always appeared



My source code is from this website : https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_asset



However, I changed the source code, the result is always a Blue Cube.



Can anyone help?



thanks in advance

Hm, what does your source code look like ?

import com.jme3.app.SimpleApplication;

import com.jme3.font.BitmapText;

import com.jme3.light.DirectionalLight;

import com.jme3.material.Material;

import com.jme3.math.Vector3f;

import com.jme3.scene.Geometry;

import com.jme3.scene.Spatial;

import com.jme3.scene.shape.Box;



/** Sample 3 - how to load an OBJ model, and OgreXML model,

  • a material/texture, or text. */

    public class HelloAssets extends SimpleApplication {



    public static void main(String[] args) {

    HelloAssets app = new HelloAssets();

    app.start();

    }



    @Override

    public void simpleInitApp() {



    Spatial teapot = assetManager.loadModel(“Models/Teapot/Teapot.obj”);

    Material mat_default = new Material(

    assetManager, “Common/MatDefs/Misc/ShowNormals.j3md”);

    teapot.setMaterial(mat_default);

    rootNode.attachChild(teapot);



    // Create a wall with a simple texture from test_data

    Box box = new Box(Vector3f.ZERO, 2.5f,2.5f,1.0f);

    Spatial wall = new Geometry(“Box”, box );

    Material mat_brick = new Material(

    assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);

    mat_brick.setTexture(“ColorMap”,

    assetManager.loadTexture(“Textures/Terrain/BrickWall/BrickWall.jpg”));

    wall.setMaterial(mat_brick);

    wall.setLocalTranslation(2.0f,-2.5f,0.0f);

    rootNode.attachChild(wall);



    // Display a line of text with a default font

    guiNode.detachAllChildren();

    guiFont = assetManager.loadFont(“Interface/Fonts/Default.fnt”);

    BitmapText helloText = new BitmapText(guiFont, false);

    helloText.setSize(guiFont.getCharSet().getRenderedSize());

    helloText.setText(“Hello World”);

    helloText.setLocalTranslation(300, helloText.getLineHeight(), 0);

    guiNode.attachChild(helloText);



    // Load a model from test_data (OgreXML + material + texture)

    Spatial ninja = assetManager.loadModel(“Models/Ninja/Ninja.mesh.xml”);

    ninja.scale(0.05f, 0.05f, 0.05f);

    ninja.rotate(0.0f, -3.0f, 0.0f);

    ninja.setLocalTranslation(0.0f, -5.0f, -2.0f);

    rootNode.attachChild(ninja);

    // You must add a light to make the model visible

    DirectionalLight sun = new DirectionalLight();

    sun.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f));

    rootNode.addLight(sun);



    }

    }

Its because the main class is still the one that was created with the project. Either set the new main class in the project settings or just right-click your new class in the Project Explorer and select “run” in the popup if its just testing.
