It appears that something is missing since we have light and reflection but no shadows. Shadow in LibGDX is still evolving. The way of using shadows might change in the next version. However, we will simply put a shadow here just to make the scene look more complete:
DirectionalShadowLight shadowLight;
ModelBatch shadowBatch;
@Override
public void create() {
. . .
environment = new Environment();
environment.set(new ColorAttribute(ColorAttribute.AmbientLight, .4f, .4f, .4f, 1f));
environment.add(new DirectionalLight().set(0.8f, 0.8f, 0.8f, -1f, -0.8f, -0.2f));
shadowLight = new DirectionalShadowLight(1024, 1024, 60, 60, 1f, 300);
shadowLight.set(0.8f, 0.8f, 0.8f, -1f, -.8f, -.2f);
environment.add(shadowLight);
environment.shadowMap = shadowLight;
shadowBatch = new ModelBatch(new DepthShaderProvider());
. . .
}
@Override
public void render() {
//update the world
. . .
shadowLight.begin(Vector3.Zero, cam.direction);
shadowBatch.begin(shadowLight.getCamera());
for (UserData data : UserData.data) {
shadowBatch.render(data.getInstance());
}
shadowBatch.end();
shadowLight.end();
. . .
// draw the modelBatch
}
@Override
public void dispose() {
. . .
shadowBatch.dispose();
shadowLight.dispose();
}The shadowLight object is an object of DirectionalShadowLight and shadowBatch is ModelBatch with a depth shader. The model instances are rendered using shadowBatch to simulate the shadows near the actual model instances.
Here is the screenshot of the scene with shadows enabled:
