Why are packages not available (5 posts)

    Hello,
    I am a beginner in JMonkeyEngine and I started today to learn more about this engine.

    I began to make the tutorials on this page. And I have a problem.
    The first Tutorial requires to import com.jme3.app.SimpleApplication.
    JME says that this package doesn`t exists.

    Where is the problem? With the installation of JME all packages have to
    be installed with.

    Thanks for help.

    Sorry if I make mistakes in my language. English isn`t my mother tongue.

    Oh I found the problem. I had to make a JME Project. I made first a AssetPack Project.
    But I surely will have more questions today.

    Now I have a new question.

    My Code:

    
package Uebung2;

import com.jme3.app.SimpleApplication;
import com.jme3.font.BitmapText;
import com.jme3.light.DirectionalLight;
import com.jme3.material.Material;
import com.jme3.math.Quaternion;
import com.jme3.math.Vector3f;
import com.jme3.scene.Geometry;
import com.jme3.scene.Spatial;
import com.jme3.scene.shape.Box;

public class Uebung2 extends SimpleApplication{

    public static void main(String[] args){
        Uebung2 uebung2 = new Uebung2();
        uebung2.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);

        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);
        rootNode.attachChild(wall);

        DirectionalLight light = new DirectionalLight();
        light.setDirection(new Vector3f(-0.1f,-0.7f, -1.0f));
        rootNode.addLight(light);

    }

}

    The program doesn`t show mistakes in the Engine but if I start it, it closes itself.

    I think the reason is, because I haven`t the data Unshaded.j3md in my MatDefs Folder.
    Brickwall.jpg is also missing.

    Where can I download this two files to start the programm.

    Make sure you see the “Projects” tab on the left side in the IDE. There should be a node called “Libraries” there.
    Make sure it lists “jme3 – jME3-core.jar” and “jme3-test-data – jME-testdata.jar”.

    The “Common/MatDefs/Misc/…” are located inside the core JAR-file. The other resources you want to use are in the test-data.jar.

    Hope that helps.

    Cheers,
    Johan Maasing

    You should read the documentation. Really, this would have answered all your questions. http://jmonkeyengine.org/wiki/doku.php/jme3#tutorials_for_beginners
