Simple One Way Communication
« on: November 07, 2013, 01:22:16 AM »
Hi,

I have a project that is split between a UI application on a touch display (UI.exe), and a 3D content program on a huge wall display (3d.exe).

I just need to send one way commands from UI.exe to 3d.exe.

Since i love NGUI, i purchased Tnet to do it, but i am kinda stuck, and under a heavy deadline (work as usual...).

Would you be so kind as to give just a quick example of sending a simple color change command initiated by a mouse click from UI.exe that changes the color of anything in 3d.exe?

One example and i can get it from there.

Thanks so much,
zipper

If they are on the same LAN, then it's actually ridiculously easy. Just use the BroadcastToLAN functionality (you don't even need to connect)
  1. using UnityEngine;
  2. using TNet;
  3.  
  4. public class Test : TNBehaviour
  5. {
  6.         void Start ()
  7.         {
  8.                 TNManager.StartUDP(5128);
  9.         }
  10.  
  11.         void OnClick ()
  12.         {
  13.                 tno.BroadcastToLAN(5128, "SetColor", Color.red);
  14.         }
  15.  
  16.         [RFC]
  17.         void SetColor (Color c)
  18.         {
  19.                 Debug.Log("My color is now " + c);
  20.         }
  21. }

One more question  ;D

How would i make this work if both applications are running on the same machine? From what i understand, i can't bind a udp port with one .exe and have another .exe listen to the same port on the same machine. Is this correct?

Sorry for the noobness :(

You can't use broadcast to LAN for two instances running on the same machine. You need to use different machines, or establish a connection from one to another first, then use regular RFCs.
