Hey guys i need help with this, i’m just trying to apply texture on the box object…
and here’s the error :
Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]
IllegalArgumentException: Expected a Int Value!

i followed the code that i saw in one of jmonkey tutorials…
please … i’m very new at this. thank you very much

Here’s the Code:
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.texture.Texture;

public class Main extends SimpleApplication {

public static void main(String[] args) {
    Main app = new Main();
    app.start();
}

@Override
public void simpleInitApp() {
    Box one = new Box(1, 1, 1);
    Geometry paddleOne = new Geometry("Box", one);
    Material paddleOneMat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
    Texture paddleOneText = assetManager.loadTexture("Textures/paddle.jpg");
    paddleOneMat.setTexture("Color", paddleOneText);
    paddleOne.setMaterial(paddleOneMat);
    paddleOne.setLocalTranslation(new Vector3f(-4,0,0));
    rootNode.attachChild(paddleOne);
}

@Override
public void simpleUpdate(float tpf) {
    //TODO: add update code
}

@Override
public void simpleRender(RenderManager rm) {
    //TODO: add render code
}

}

Can you give the full error?

3

Is the texture resolution a power of two? (16x16, 32x32, 64x64, etc…)

4

In the future, don’t bother mentioning an exception without including the stack trace. It’s almost just as good.

5

600x450 pixels
it’s a jpg

Try with a power of two texture. It still gives you an error?

8

Try replacing this line:
paddleOneMat.setTexture("Color", paddleOneText);
with:
paddleOneMat.setTexture("ColorMap", paddleOneText);

9

In Unshaded.j3md ths Parameters are defined as follow. Use “ColorMap” instead of “Color”.

MaterialParameters {
    Texture2D ColorMap
    Texture2D LightMap
    Color Color (Color)

    //...

}
