Using Slick2D and Kryonet:
Lets say a server sends a (TCP) packet to a client with X and Y coordinates. The client receives this packet in the NetworkListener and the goal is to call drawString(“hihi”,x,y) respectively. The issue clearly is: there is not an OpenGL context in this thread to make this function call happen.
For your entertainment, I have tried the following with no success!
public class ClientStart extends StateBasedGame {
/* lots of networking code */
public static void main(String[] args) {
/* code */
}
}
public class NetworkListener extends Listener {
ClientStart client; // assume this has been initialized properly to the main class
/* more missing code */
public void received(Connection con, Object obj) {
client.getContainer().getGraphics().drawString("hihi",x,y); // this fails.
}
}
How should the client go about ‘finding’ the current GameState (which contains the OpenGL context), or better yet, how should one attack this problem?
Thank you
