2d + 3d = crash

[woozie]

using latest pseudo stable CS/CEL, compiled on latest mingw and mysy, windows xp pro. Trying to simply print text over a 3d room.
I know this has been covered in nemourous places but all the soultions ive read have led me to the code i got now, wich is only crashing the app as soon as i start it. editing around simpmap tutorial.

in simpmap.h ive got

Code:

csRef<iGraphics3D> g3d;
csRef<iGraphics2D> g2d;
csRef<iFontServer> fntsvr;
csRef<iFont> font;

and in the simpmap.cpp

Code:

void Simple::ProcessFrame ()
{
  // First get elapsed time from the virtual clock.
  csTicks elapsed_time = vc->GetElapsedTicks ();
 

 
//Mouse look 
   
                  int w = g3d->GetDriver2D ()->GetWidth()/2;  //sets w = top screen width
                  int h = g3d->GetDriver2D ()->GetHeight()/2; //sets h = to screen height.

 
                  int x = mouse->GetLastX(); 
                  int y = mouse->GetLastY();
                  view->GetCamera ()->GetTransform ().RotateThis (CS_VEC_TILT_DOWN, (y-h) * 0.01);
                  view->GetCamera ()->GetTransform ().RotateOther (CS_VEC_ROT_RIGHT, (x-w) * 0.01);
                  g3d->GetDriver2D ()->SetMousePosition (w, h);
                 
////////////////
 
 
csVector3 obj_move (0);
csVector3 obj_rotate (0);
 

 
//keyboard controls   
    if (kbd->GetKeyState (CSKEY_RIGHT))
    {
      obj_move = CS_VEC_RIGHT * 3.0f;
      //view->GetCamera ()->GetTransform ().RotateOther (CS_VEC_ROT_RIGHT, (x-w) * 0.01);
    }
    if (kbd->GetKeyState (CSKEY_LEFT))
    {
      obj_move = CS_VEC_LEFT * 3.0f;
      //view->GetCamera ()->GetTransform ().RotateOther (CS_VEC_ROT_RIGHT, (x-w) * 0.01);
    }
    if (kbd->GetKeyState (CSKEY_UP))
    {
      obj_move = CS_VEC_FORWARD * 3.0f;
      //view->GetCamera ()->GetTransform ().RotateThis (CS_VEC_TILT_DOWN, (y-h) * 0.01);
    }
    if (kbd->GetKeyState (CSKEY_DOWN))
    {
       obj_move = CS_VEC_BACKWARD * 3.0f;
       //view->GetCamera ()->GetTransform ().RotateThis (CS_VEC_TILT_DOWN, (y-h) * 0.01);
    } 
     


  collider_actor.Move (float (elapsed_time) / 1000.0f, 1.0f,
    obj_move, obj_rotate);




 // Tell 3D driver we're going to display 3D things.
 if (!g3d->BeginDraw (engine->GetBeginDrawFlags () | CSDRAW_3DGRAPHICS))
 return;
   //Tell the camera to render into the frame buffer.
 view->Draw ();
 
  ////////////////////////
 
   if (!g3d->BeginDraw (CSDRAW_2DGRAPHICS))
   return;
   int fg = g2d->FindRGB (255, 0, 0);  // Red.
   fntsvr = g2d->GetFontServer();
   font = fntsvr->LoadFont(CSFONT_COURIER);
   g2d->Write (font, 20, 20, fg, -1, "text");

 
}

void Simple::FinishFrame ()
{
  // Just tell the 3D renderer that everything has been rendered.
  g3d->FinishDraw ();
 
}

Anyone got any idea why this causes it to crash?

[jorrit]

Can you check in a debugger where it crashes exactly?

Greetings,

[woozie]

debugging the source it crashes when it hits the line

 

Code:

return csApplicationRunner<Simple>::Run (argc, argv);

now that doesnt seem like much help so i ran the executable through windows debugger, now I myself can only understand half this log but i dont know if any of you can get any help out of this.

Im starting to think something in the instalation might just be corrupt, if this doesnt give you any idea im going to try downloading and building CS/Cel again. then running it through.  Also some aditional info. Im using Dev cpp 4.9.9.2, graphics card is radeon 9800xt pro, all drivers are up to date. Also when the app is ran, the 3d window is opened and intializaed, nothing is shown but a black screen, it flickers twice (changes black to white really quickly) then crashes. Also if I remove the 2d functions in there, it runs fine.

[jorrit]

Can you check in a debugger that shows C++ line numbers please? Also make sure to compile Crystal Space and your application in debug mode so that you can see the actual line where it crashes.

Greetings,

I'm not sure what the problem is, but when I was fiddling with font stuff, I would always get a program crash, too.

Make sure that you check all your pointers before you try to use them... so for instance, when you do

Code:

fntsvr = g2d->GetFontServer();
font = fntsvr->LoadFont(CSFONT_COURIER);

I would do

Code:

fntsvr = g2d->GetFontServer();
if(!fntsvr.isValid()) { ReportError("Couldn't get font server!"); return; }
font = fntsvr->LoadFont(CSFONT_COURIER);
if(!font.isValid()) { ReportError("Couldn't load font!"); return; }

(I might have gotten the isValid() function name wrong, but you get the idea.)

Another caveat: if you try to load a ttf font (it doesn't look like you're trying to do that, but if you decide to), make sure you request the right plugin, i.e. do

CS_REQUEST_PLUGIN("crystalspace.font.server.freetype2", iFontServer)

not

CS_REQUEST_FONTSERVER

because, as I discovered (the hard way and after much frustration), CS_REQUEST_FONTSERVER is a #define for the non-freetype font server, which cannot load ttf files.  You might already know this, but I had a hard time with it so I'm just putting it out there.

Good luck,
-Yoshi

Sorry it took me so long to respond, Anyway i solved this one myself. I was loading the font up in the OnInitialize section, like its done in waterdemo, and it didnt really like that. Ive got a couple of new questions though...

What I want to do (without using aws or cegui) is make...well pretty much the same thing as a consol, but...without using the pre built consol aswell, as that doesnt suit my needs.

I need the user to press a key, say enter. and it will print onto the screen a prompt and take a string, hitting enter closing the prompt again. now the printing is all fine, but when i use  kbd->GetKeyState the prompt is only displayed well the key is held, is there anyway of saying - if (key was pressed) - do this until key is pressed again? (the way ive currently got it is messy as it gets, a boolean, being set back and forth true or false to display the prompt)

And also how can I take in the string? I assume just basic cin wont work, with cs's keyboard objects handling everything.
 
The way im currently printing is just a function i made up quick, to simplify things.

Code:

bool printcon(int r, int g, int b,const char *str)
      {
            if (!g3d->BeginDraw (CSDRAW_2DGRAPHICS))
            {
                 return 0;               
            }                               
            font = g3d->GetDriver2D ()->GetFontServer()->LoadFont(CSFONT_LARGE);
            int glyphWidth, glyphHeight;
            font->GetMaxSize (glyphWidth, glyphHeight);
            int white = g3d->GetDriver2D ()->FindRGB (r, g, b);
            g3d->GetDriver2D ()->Write (font, 1,g3d->GetDriver2D ()->GetHeight () - (glyphHeight == -1? 20 : (glyphHeight+1)),white, -1, str);
           
      }

And of course by made up, its pulled out of snippets of code from various examples....Ive been using C/++ forever, just never got into oop, I had to go off and learn assembly instead >.<. im not quite used to thinking in the object oriented way yet =P

I need the user to press a key, say enter. and it will print onto the screen a prompt and take a string, hitting enter closing the prompt again. now the printing is all fine, but when i use  kbd->GetKeyState the prompt is only displayed well the key is held, is there anyway of saying - if (key was pressed) - do this until key is pressed again? (the way ive currently got it is messy as it gets, a boolean, being set back and forth true or false to display the prompt)

Well best is to use event handling. Don't use GetKeyState() but act on the keys in the event handler. Maybe check out the input console plugin source code on how it does that.
