Unity FBO - linker error wxDec++

Recommended Posts

As I described in a previous thread (http://www.gamedev.net/community/forums/topic.asp?topic_id=513833) my problem is that i can't render the scene on every PaintEvent because there are to many float-values to calculate. No i tried to use a FrameBufferObject with following code:
   glGenFramebuffersEXT(1, &fboId);
Render();
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0);


Now the linker says: [Linker Error] undefined reference to glBindFramebufferEXT@8' [Linker Error] undefined reference to glGenFramebuffersEXT@8' I looked @ the gltext.h and didn't found the functions. So i Downloaded the latest mensa-3d, compiled it and put the lib-files @ the correct place. It compiles, but my application hang up @ execution-start (with FBO-code and without it). I recognize that the problem is the "libopengl32.a" file. With the selfcompiled it compiles but doesn't work. With the "standard" lib-file i get the Linker-error. Any suggestions?

FBO is supported in opengl (<3.0) via extensions, the easiest way to access those extensions is to use a library like GLee or GLEW. You don't need Mesa. The latest extension headers can be downloaded from www.opengl.org/registry/ .
FAQ: How can I program for OpenGL beyond version 1.1 in windows?

FBOs are a bit more complicated to use than just calling glGenFramebuffersEXT, I suggest reading the following articles:
OpenGL FrameBuffer Object 101
OpenGL FrameBuffer Object 201

"Alternative Game Libraries" is probably the wrong forum, you may want to ask a moderator to move this thread to the OpenGL forum.

I just saw their courses were knocked down to \$10 each and figured I'd share the info here. They have stuff for Unity, Unreal, drawing, business, etc. I haven't used their stuff before, but the previews I looked at seemed pretty good and there is a user review system as well.

• I am working on a game in which we control a rectangular box at the bottom of the screen. Three sphere which has alphabets in it fall down. When the game starts, a word is generated from the predefined list of words(which I'll give) and we are supposed to touch the correct sphere having the alphabet based on that word. The question is how to detect if I have touched the correct sphere.
secondly, if I have touched a correct sphere before and there is no recurrence of that alphabet in that word then during the second wave the game should not proceed if I touch the same alphabet again.
Looking forward to your answers, i have to submit this project in a couple of days. please help! (Working on Unity 3D)
Thanks

• Hey guys,   As the title says, I'm trying to control a desktop game by using my mobile phone as a controller.  I created two scenes, one that acts as a server, other as a client.    Server has this code: void Start () {         Test = "Nothing yet happened";         NetworkServer.Listen(25000);         NetworkServer.RegisterHandler(888, ServerReceiveMessage);     }         private void ServerReceiveMessage(NetworkMessage message)     {                 StringMessage msg = new StringMessage();         msg.value = message.ReadMessage<StringMessage>().value;         if (!String.IsNullOrEmpty(msg.value))         {             Test = "Message received";             string[] deltas = msg.value.Split('|');             Horizontal = Convert.ToSingle(deltas[0]);             Vertical = Convert.ToSingle(deltas[1]);             TestScript.MoveForward(Vertical);             TestScript.RotateAroundY(Horizontal);         }         else         {             Test = "Nothing received";         }     }
And client this:  private void Connect()     {              client.Connect(IPAddress, 25000);           }     void Start () {         client = new NetworkClient();         Connect();            }         void Update () {    #if UNITY_ANDROID         MobileTouches = Input.touches;         if (MobileTouches.Length > 0)         {             for (int i = 0; i < MobileTouches.Length; i++)             {                 if (MobileTouches[i].phase == TouchPhase.Moved)                 {                     Horizontal = MobileTouches[i].deltaPosition.x;                     Vertical = MobileTouches[i].deltaPosition.y;                 }else if(MobileTouches[i].phase == TouchPhase.Stationary)                 {                     Connect();                                  }             }         } #elif UNITY_EDITOR               Horizontal = Input.GetAxis("Horizontal");         Vertical = Input.GetAxis("Vertical"); #endif         thumb.Translate(Vector3.up * Vertical * Time.deltaTime);         thumb.Translate(Vector3.right * Horizontal * Time.deltaTime);         SendControllerInfo();     }     static public void SendControllerInfo()     {         if (client.isConnected)         {             StringMessage msg = new StringMessage();             msg.value = Horizontal + "|" + Vertical;             client.Send(888, msg);         }     }
Ip address is hard coded, I just replaced it with the "IpAddress" variable. The code itself builds fine, and when I try to run in on a desktop computer, it works as expected (just a simple movement of an object on the server screen). However when I try to publish the client scene to a mobile device (Android), it doesn't connect to the server. They are both connected to the same network. Can anyone tell me what the problem might be?   Thanks
