Newcomer, code won't work

dudio · February 23, 2011, 4:54pm

When I try to run this code, I get a blank screen then it just closes…not even showing my box.

[java]

package mygame;

import com.jme3.app.SimpleApplication;

import com.jme3.material.Material;

import com.jme3.math.ColorRGBA;

import com.jme3.math.Vector3f;

import com.jme3.renderer.RenderManager;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.scene.Node;

/**

test
@author normenhansen

*/

public class Main extends SimpleApplication {

public static void main(String[] args) {

Main app = new Main();

app.start();

}

@Override

public void simpleInitApp() {

Box box1 = new Box(new Vector3f(1f, 1f, -5f), 1, 1, 1);

Geometry blue = new Geometry("Box", box1);

Material mat1 = new Material(assetManager, "Common/MatDefs/Misc/SolidColor.j3md");

mat1.setColor("m_color", ColorRGBA.Blue);

blue.setMaterial(mat1);

Node boxes = new Node("boxes");

rootNode.attachChild(boxes);

boxes.attachChild(blue);

boxes.rotate(0.4f, 0.4f, 0.0f);

}

}

[/java]

wth is wrong here? O_o

Whats the output of the application? Also, there is no parameter “m_color”, maybe you mean “m_Color”?

Yeah, what I said:

java.lang.IllegalArgumentException: Material parameter is not defined: m_color

lol that's it. Thanks man. :p

dudio · February 23, 2011, 5:16pm

Hey I have one more question. I have access to 3dsmax for models and I was wondering if this will be an issue or can I load models from 3ds as easily as blender?

If so, what is the method for 3ds max to JMonkey?

WASD · February 23, 2011, 5:32pm

There is an Ogre XML exporter for 3DS Max available on their official page: http://www.ogre3d.org/tikiwiki/OGRE+Exporters

I have only tried it with Blender but I guess it should work well with 3DS Max too.

dudio · February 23, 2011, 5:56pm

Thanks…I hope this thing works. I am familiar with 3dsMax so blender will be a pain to learn w/ all those 50 million shortcut keys. D:

dudio · February 23, 2011, 5:59pm

Do I export the models as .obj or .scene?
