The <code>com.jme3.application</code> provides a toolset for jME3 applications
to interact with various components of the engine. Typically, the
{@link com.jme3.app.Application} class will be extended and the update() method
implemented to provide functionality for the main loop. <br>
<p>
An <code>Application</code> will typically provide the following services:
<ul>
<li>{@link com.jme3.asset.AssetManager} - A system for finding and loading
data assets included with the application, such as models and textures.</li>
<li>{@link com.jme3.renderer.RenderManager} - A high-level rendering
interface for 3D graphics, manages viewports and scenes assigned
to the viewports, as well as general high-level rendering.</li>
<li>{@link com.jme3.input.InputManager} - An interface for handling input
from devices such as keyboard, mouse, and gamepad/joystick.</li>
<li>{@link com.jme3.app.state.AppStateManager} - Manager for
{@link com.jme3.app.state.AppState}s, which are specific application
functionality to be executed inside the main loop.</li>
<li>{@link com.jme3.audio.AudioRenderer} - Allows playing sound effects and
music.</li>
<li>{@link com.jme3.system.Timer} - The timer keeps track of time and allows
computing the time since the last frame (TPF) that is neccessary
for framerate-independent updates and motion.</li>
<li>{@link com.jme3.system.AppSettings} - A database containing various
settings for the application. These settings may be set by the user
or the application itself.</li>
</ul>
<h3>Usage</h3>
An example use of the Application class is as follows<br>
<br>
<code>
public class ExampleUse extends Application {<br>
<br>
private Node rootNode = new Node("Root Node");<br>
<br>
public static void main(String[] args){<br>
ExampleUse app = new ExampleUse();<br>
app.start();<br>
}<br>
<br>
@Override<br>
public void initialize(){<br>
super.initialize();<br>
<br>
// attach root node to viewport<br>
viewPort.attachScene(rootNode);<br>
}<br>
<br>
@Override<br>
public void update(){<br>
super.update();<br>
<br>
float tpf = timer.getTimePerFrame();<br>
<br>
// update rootNode<br>
rootNode.updateLogicalState(tpf);<br>
rootNode.updateGeometricState();<br>
<br>
// render the viewports<br>
renderManager.render(tpf);<br>
}<br>
}<br>
<br>
</code>
