Class RemoteInput

java.lang.Object

com.badlogic.gdx.input.RemoteInput

All Implemented Interfaces:

Input, Runnable

public class RemoteInput
extends Object
implements Runnable, Input

An Input implementation that receives touch, key, accelerometer and compass events from a remote Android device. Just instantiate it and specify the port it should listen on for incoming connections (default 8190). Then store the new RemoteInput instance in Gdx.input. That's it.

On your Android device you can use the gdx-remote application available on the Google Code page as an APK or in SVN (extensions/gdx-remote). Open it, specify the IP address and the port of the PC your libgdx app is running on and then tap away.

The touch coordinates will be translated to the desktop window's coordinate system, no matter the orientation of the device
