Alright, well I would like to make a little code for drawing the names of players on my team. Not the enemy, only for team. Instead of when you move your crosshair over them, it always shows their name. The problem is I don't know what i'm doing wrong. Here's the code.

#define FONTSCALE 0.45f

char *info_getname (int index);
int info_getteam (int index);

char *Info_ValueForKey (const char *s, const char *key);

const char *
CONFSTR (int index)
{
  gameState_t *gs;
  extern gameState_t gstemp;
  return cgs.gameState.stringData + cgs.gameState.stringOffsets[ index ];
}

char *info_getname (int index)
{
  return Info_ValueForKey (CONFSTR (CS_PLAYERS + index), "n");
}

int info_getteam (int index)
{
  return atoi (Info_ValueForKey (CONFSTR (CS_PLAYERS + index), "t"));
}

qhandle_t font = 0;
int fontheight = 0;

void CG_MatrixEsp( playerState_t *ps, centity_t *cent ) 
{
	entityState_t *es = &cent->currentState;
	vec4_t red = { 1.0f, 0.0f, 0.0f, 1.0f };
	vec4_t green = { 0.0f, 1.0f, 0.0f, 1.0f };
	float		*color;
	int x, y;
	char *s, *s2;
	int w;
	entityState_t	*ent;


	if (!font)
    {
      font = cgs.media.hudFont;
      fontheight = trap_R_GetTextHeight ("|", font, FONTSCALE, 0);
	}	

	  if (!CG_WorldCoordToScreenCoord (cent->lerpOrigin, &x, &y))
    return;

	if ( cgs.gametypeData->teams && cg_teamCheck.integer > 0 )
	{
		if (cg_teamCheck.integer == 1)
		{
			if (info_getteam (cent->currentState.number) ==
              info_getteam (ps->clientNum))
            color = (float *) &green;   // friendly
             }
  if (cg_matrixEsp.integer == 1 || cg_matrixEsp.integer == 3)
  {
	  s = info_getname (cent->currentState.number);
      CG_DrawText ((x - trap_R_GetTextWidth (s, font, FONTSCALE, 0) / 2),
                       y - fontheight, font, FONTSCALE, color, s, 0, 0);
  }

The problem is, nothing even draws. No text. Any help would be great.

I made a huge reply lastnight then came back just now and read it.  It didnt even make sense to me  .

Basically, you are doing A LOT more then you need to be doing.  You can get the player name and team via cgs.clientinfo.

Also the worldcoornates will work, just make sure its only drawing it if its in the bounds of the virtual screen (480x640).

Lastly, make sure its ran every frame for each client, that way the text can be seen by human eyes.  It would probably be better to check each client in one call using a loop statement.

Could I use cg.screenYScale and cg.screenXScale?

All resolutions are based off 640x480 and then scaled from there.

Just use the SCREEN_WIDTH/SCREEN_HEIGHT DEFINES.

if(y < 0 || y >= SCREEN_HEIGHT)
 continue;
if(x < 0 || x > SCREEN_WIDTH)
 continue;

Thanks for the reply. So how about this?


vec4_t green = { 0.0f, 1.0f, 0.0f, 1.0f };
float *color;
int x,y;
char *name;

if(y < 0 || y >= SCREEN_HEIGHT)
continue;
if(x < 0 || x > SCREEN_WIDTH)
continue;
{
if (!CG_WorldCoordToScreenCoord (cent->lerpOrigin, &x, &y))
  return;
}
if ( cgs.gametypeData->teams)
{
if (ci->team == cgs.clientinfo.team)
          color = (float *) &green;   // friendly
           }
if (cg_Esp.integer == 1)
{
name = cgs.clientinfo.name;

I don't know if this is right. How would I draw text after this?  

Try something like this.  I added some extra stuff, like distance checks, dead/respawing checks, etc..

Code Sample

void CG_Matrix (void) { int i, x, y; int width; centity_t* cent; vec3_t dirPlayer; float distance; if ( !cgs.gametypeData->teams ) return; for ( i = 0; i < cgs.maxclients; i ++ ) { if ( cgs.clientinfo[i].team != cgs.clientinfo[cg.snap->ps.clientNum].team ) continue; cent = CG_GetEntity (i); if(cg.snap->ps.clientNum == cent->currentState.clientNum) continue; if(cent->currentState.eFlags & EF_DEAD) continue; if(cgs.clientinfo[i].health <= 0) continue; if (CG_WorldCoordToScreenCoord (cent->lerpOrigin, &x, &y)) { if(y < 0 || y >= SCREEN_HEIGHT) continue; if(x < 0 || x > SCREEN_WIDTH) continue; VectorSubtract ( cg.predictedPlayerState.origin, cent->lerpOrigin, dirPlayer ); dirPlayer[2] = 0; distance = VectorNormalize ( dirPlayer ); if ( distance > 1800) continue; if ( distance < 200) continue; width = trap_R_GetTextWidth (cgs.clientinfo[i].name, cgs.media.hudFont, 0.38f / (distance / 300 ), 0); CG_DrawText ((x - (width/2)), y - (150 / (distance / 150 )), cgs.media.hudFont, 0.38f / (distance / 300 ), colorGreen, cgs.clientinfo[i].name, 0, 0); } } }

Alright, thanks man i'll give it a shot and let you know soon. My motherboard fried, and I can't get back on my system, so i'll have to download the source code on this computer, and test it out until newegg can send me a replacement.  

Sorry for the doublepost. I compiled it and all went well, but nothing drew still on screen or on players. No text. Any suggestions. Thanks man.  

Make sure you are calling your CG_Matrix function.

Add it to the end of the CG_Draw2D function and it should work.

Hmm. Weird. I have called the matrix function.

void CG_Matrix (void)
{
int i, x, y;
int width;
centity_t* cent;
vec3_t dirPlayer;
float distance;

if ( !cgs.gametypeData->teams )
return;

for ( i = 0; i < cgs.maxclients; i ++ )
{

if ( cgs.clientinfo.team != cgs.clientinfo[cg.snap->ps.clientNum].team )
continue;
cent = CG_GetEntity (i);

if(cg.snap->ps.clientNum == cent->currentState.clientNum)
continue;

if(cent->currentState.eFlags & EF_DEAD)
continue;
if(cgs.clientinfo.health <= 0)
continue;


if (CG_WorldCoordToScreenCoord (cent->lerpOrigin, &x, &y))
{
if(y < 0 || y >= SCREEN_HEIGHT)
continue;
if(x < 0 || x > SCREEN_WIDTH)
continue;

VectorSubtract ( cg.predictedPlayerState.origin, cent->lerpOrigin, dirPlayer );
dirPlayer[2] = 0;
distance = VectorNormalize ( dirPlayer );

if ( distance > 1800)
continue;
if ( distance < 200)
continue;

width = trap_R_GetTextWidth (cgs.clientinfo.name, cgs.media.hudFont, 0.38f / (distance / 300 ), 0);
CG_DrawText ((x - (width/2)), y - (150 / (distance / 150 )), cgs.media.hudFont, 0.38f / (distance / 300 ), colorGreen, cgs.clientinfo.name, 0, 0);

}
}
}

Then under 2d

if ( cg.snap->ps.pm_type == PM_SPECTATOR || cg.snap->ps.persistant[PERS_TEAM] == TEAM_SPECTATOR )
{
CG_DrawSpectator();
CG_DrawCrosshair();
CG_DrawCrosshairNames();
CG_DrawHUDIcons();
CG_Matrix();
}
