Time for action – unshaded materials


In the previous chapters, you used a plain, unshaded material to create a simple blue cube. Look at the blue cube's code again. The cube's material is based on the Unshaded.j3md material definition, and it has a Color property that is set to ColorRGBA.Blue.

Material mat = new Material(assetManager,
  "Common/MatDefs/Misc/Unshaded.j3md");
mat.setColor("Color", ColorRGBA.Blue);

Let's see what else this material can do:

  1. Make a copy of Main.java and name the class MaterialsUnshaded.java. Remember to also refactor the first line of the main() method to MaterialsUnshaded app = new MaterialsUnshaded();.

  2. Copy the provided image assets/Interface/Monkey.png into your project's assets/Interface/ directory.

  3. Replace the blue cube code in simpleInitApp() with the following code:

    Sphere sphereMesh = new Sphere(16, 16, 1);
    Geometry sphereGeo = new Geometry("Unshaded textured sphere",sphereMesh);
    sphereGeo.move(-2f, 0f, 0f);
    sphereGeo.rotate(FastMath.DEG_TO_RAD * -90, 
      FastMath...
