Map HUD

#1 Now, to integrate this with the Radar, and we have a winner :)

Seriiously, I had been trying to get the existing terrain editor control to do exactly that, and all I ever got was a black screen with a nice arrown on it :)

Thanks!!

#2 Excellent! I think I'll add a toggle to it.
Ooops...the download link seems to be broken. Nevermind, I DLd from your post :)

#3 How difficult would it be to alter this to show the outline of interior objects as well? I think that would be quite good if possible.

Well Done :)

#4 Frank,
the function dglDrawBitmapRotated() you use doesn't seem to be defined anywhere in the engine... could you please provide it?
Thanks!! :-)

#5 dglDrawBitmapRotated is defined in an early resources posted here (did not remember if it's Phil or Matt who posted it). Here is the code BTW :

//*********
void dglDrawBitmapRotated(TextureObject *texture,const RectI& dstRect,const RectI& srcRect,const U32 in_flip,F32 spinAngle)
{
   AssertFatal(texture != NULL, "GSurface::drawBitmapStretchSR: NULL Handle");
   if(!dstRect.isValidRect())
      return;
   AssertFatal(srcRect.isValidRect() == true,
               "GSurface::drawBitmapRotated: routines assume normal rects");

   glEnable(GL_TEXTURE_2D);
   glBindTexture(GL_TEXTURE_2D, texture->texGLName);
   glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);

   glEnable(GL_BLEND);
   glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

   glDisable(GL_LIGHTING);

   F32 texLeft   = F32(srcRect.point.x)                    / F32(texture->texWidth);
   F32 texRight  = F32(srcRect.point.x + srcRect.extent.x) / F32(texture->texWidth);
   F32 texTop    = F32(srcRect.point.y)                    / F32(texture->texHeight);
   F32 texBottom = F32(srcRect.point.y + srcRect.extent.y) / F32(texture->texHeight);

   F32 screenLeft   = dstRect.point.x;
   F32 screenRight  = dstRect.point.x + dstRect.extent.x;
   F32 screenTop    = dstRect.point.y;
   F32 screenBottom = dstRect.point.y + dstRect.extent.y;

   if(in_flip & GFlip_X)
   {
      F32 temp = texLeft;
      texLeft = texRight;
      texRight = temp;
   }
   if(in_flip & GFlip_Y)
   {
      F32 temp = texTop;
      texTop = texBottom;
      texBottom = temp;
   }
   
   glColor4ub(sg_bitmapModulation.red,
             sg_bitmapModulation.green,
             sg_bitmapModulation.blue,
             sg_bitmapModulation.alpha);
  
   F32 X = 0;

   // calculate the centroid of the rectangle (to use as rotation pivot)
   if (screenLeft < screenRight)
   {
        X = screenLeft + ((screenRight - screenLeft)*0.5f);
   }
   else
   {
        X = screenRight + ((screenLeft - screenRight)*0.5f);
   };

   F32 Y = 0;

   if (screenTop < screenBottom)
   {
        Y = screenTop + ((screenBottom - screenTop)*0.5f);
   }
   else
   {
        Y = screenBottom + ((screenTop - screenBottom)*0.5f);
   };
   
   // spin angle is in degree's so convert to radians..radians = degrees * pi /180
   spinAngle = spinAngle * 3.14 / 180.0f;

   Point2F screenPoint(X,Y); 

   F32 width = dstRect.extent.x;
   width *= 0.5;

   MatrixF rotMatrix( EulerF( 0.0, 0.0, spinAngle ) );

   Point3F offset( screenPoint.x, screenPoint.y, 0.0 );
   Point3F points[4];
   
   points[0] = Point3F(-width, -width, 0.0);
   points[1] = Point3F(-width,  width, 0.0);
   points[2] = Point3F( width,  width, 0.0);
   points[3] = Point3F( width, -width, 0.0);

   for( int i=0; i<4; i++ )
   {
      rotMatrix.mulP( points[i] );
      points[i] += offset;
   }

   glBegin(GL_TRIANGLE_FAN);
      glTexCoord2f(texLeft,texTop);
      glVertex2fv(points[0]);

      glTexCoord2f(texLeft, texBottom);
      glVertex2fv(points[1]);

      glTexCoord2f(texRight, texBottom);
      glVertex2fv(points[2]);

      glTexCoord2f(texRight, texTop);
      glVertex2fv(points[3]);
   glEnd();

   glDisable(GL_TEXTURE_2D);
}

#6 Thanks, Frank, I got it already working - Matt told us about the function in the forum thread.

Really great control, thanks very much!! I was planning to write something similar, cause I always wanted to have such cool maps as in Tribes2... and now I can use yours! :-))

#7 showing the outline of interior objects in the map would really ROCK, by the way... ;-) Any chance of giving it a try?

#8 Really cool stuff Frank.

Given that our levels will be fairly small compared to some of the landscapes we've seen under discussion, 'interior objects' support would be a boon here.

I'll enter it into our Bugzilla queue and see if someone jumps on it.

#9 I can't get it to toggle?

#10 I've got a quick and dirty Interior objects solution ... take a look at this thread...

#11 HI.. I was trying to put a map gui, I added the 'dglDrawBitmapRotated' function in the dgl.cc and the declaration in dgl.h but it returns a fatal error: unresolved external link in linking it to the MapGui.cc when I try to build it..

am I doing something wrong?

thanks..

#12 @ Architecture@UOA: have you tried CLEAN + REBUILD ALL?

#13 how can I get it so I can send commands to something eg. it gets the coonditits and sends it to a AI object and moves to that position?

#14 how can I get it so I can send commands to something eg. it gets the coonditits and sends it to a AI object and moves to that position?

#15 Like a popup command map, the maps in the middle and you have a cursor and you pick a spot on the map and it sends the coor's to the AI object, and it moves there?

#16 Frank,

What you are displaying in the map hud is basicly the heightmap for the terrain correct?
I have yet to look at the code indepth, but how hard would it be to display the The final generated texture terrain?

Regards,

Ron

#17 Im an ultra newbie to Torque and have no idea where to put dglDrawBitmapRotated, can someone tell me please. Sorry for my stupidity.

#18 dgl.cc

#19 I am sorry, but I am having a terrible time getting this to compile. Here is what I did:

1) Put guiMapCtrl.h and guiMapCtrl.cc into "torque\engine\gui"
2) Pasted the dglDrawBitmapRotated code at the bottom of dgl.cc
3) Added both files in step 1 to the project by selecting "Project -> Add to Project -> Files...".
4) Tried to build by selecting "Build", then I tried all these choices:
-"Rebuild All"
-"Build Torquedemo_DEBUG.exe"
-"Clean" then each one of the above.

I keep getting identifier errors.

Sorry I am being lame, but this is pretty new to me. I am very much a step by step guy. I am sure I missed something, or there is a fundamental step that I wasn't aware of.


Thanks,
-Jeff

#20 did you add the function declaration in dgl.h ?

if not add this

//*******
void dglDrawBitmapRotated(TextureObject *texObject,
                          const RectI&   in_rStretch,
                            const RectI&   in_rSubRegion,
                            const U32      in_flip = GFlip_None,
                            const F32 spinAngle = 0.0f,
							const Point2F spinOffset = Point2F(0,0) );
//*******

after

void dglDrawBitmap(TextureObject* texObject,
                   const Point2I& in_rAt,
                   const U32      in_flip = GFlip_None);
