[bug] game can't load because of TextDS in DrawGame

Harry · 03-24-2011 11:21 PM

Hi, I downoladed the latest version of engine and after rebuild, start and load game i get an error Unhandled exception at 0x007c9e4f in Forest Valley.exe: 0xC0000005: Access violation reading location 0xfc440b3c.

Green arrow shows this place:

TextDS ds;
ds.font =&font;
ds.scale=Vec2(0.07);

ind DrawGame. Text from call stack:

Please post some more code. Maybe problem is line above

Harry · 03-25-2011 11:45 AM

Code:

static void DrawGame()

{

    if(BL.draw())return; // this needs to be at the start of 'Draw' function

    // set field of view

    D.viewFov(DegToRad(Lerp(75,30,zoom)));

    Renderer(Render);

It's all above TextDS ds. And here is Render function:

Code:

static void Render()

{

   Game::World.draw(); // draw world (this is done outside of 'switch(Rndr())' because world automatically detects active rendering mode)

   switch(Renderer())

   {

      case RM_PREPARE:

      case RM_SOLID  :

      case RM_AMBIENT: REPAO(Bullets).draw(); break;

   }

   switch(Renderer())

   {

   case RM_PREPARE:

       {

           if(lkb_bool)

           {

               LightCone bulb(20,bulbPos,bulbDir,Vec(1,1,1),0.01); 

               bulb.add();

           }

       }

       break;

   case RM_BLEND: // alpha blending

       blood.draw(); // draw Blood Effect in Alpha Blending mode

       smokPart.draw();

       explosion.draw(); // draw Explosion Effect in the same modes as Particles are drawn

       rain.draw();

       mission.draw();

       //FogDraw(OBox(Box(D.viewRange(),D.viewRange(),D.viewRange(),Cam.matrix.pos)),0.8,​Vec(0.6));

       break;

   case RM_PALETTE:

       shotPart.draw();

       explosion.draw(); // draw Explosion Effect in the same modes as Particles are drawn

       break;

   }

}

TextDS doesn't have anything special, it's plain struct, with few members.
maybe you have bug somewhere else.
Can you post screen of VS with the issue, call stack, etc.

can you do "run to cursor" to "TextDS ds;" line,
and step line by line and check if it actually occurs in that place?

Harry · 03-25-2011 12:30 PM

When I did Run to Cursor at TextDS I have the same. I didn't have even yellow arrow which should show. I put another function between TexdDS ds; and Renderer(Render); and green arrow and error points to this function. So I tried to look inside Renred function. Game started when I comment Game::World.draw(); So I thought that it could be becuase I didn't rebuild world. So in Editor I loaded my world and when I move camera closer to terrain I get an error with application (Editor.exe don't response)

**Esenthel** · 03-25-2011 12:55 PM

you're not showing full call stack, please scroll it to the top.
most likely the error is inside Renderer(..) line above, and not TextDS

I've just tested Editor.exe for loading/building/previewing world from Esenthel RPG2 (no errors)

Harry · 03-25-2011 11:49 PM

Here is whole Call Stack.

**Esenthel** · 03-26-2011 02:53 PM

it seems to be related to a change I did last time.
Could you send me minimum amount of data (models+world) that cause the Editor to crash? so I can investigate this.

Harry · 03-26-2011 06:36 PM

I sent it to PM.

**Esenthel** · 03-26-2011 06:40 PM

Thanks, Im checking this

**Esenthel** · 03-26-2011 07:12 PM

I discovered one bug, although I couldn't reproduce the error with your data, I tested with some of my other worlds.
I will upload this in few moments, once it's ready please let me know if it's working ok for you too.

**Esenthel** · 03-26-2011 07:20 PM

autoupdate is ready, 7z will be in few minutes

Harry · 03-26-2011 08:04 PM

Thank you very much. Now everything is ok. I saw that in Version History you wrote that problem was with grass, but when I move camera closer to grass/plants or only terrain everything was ok. But only when on field of view showed other models Editor broke.
