This tut shows how to make an in-game keypress menu( it's a menu that pops up and asks you what team you want to join in spectator mode, easily modified for use while actually playing ). The code is WELL documented, so I am just gonna tell you where to paste it, then you read it :) The best thing about this menu format is that it is SO easy to add new commands and such. I have had this code done for quite some time, but it had 1 bug. Thanks to RR2D02 for showing me the nice little CG_Weapon_f hack :) Here we go!

First off, go into cg_local.h and lets declare our functions and add a variable. Go to about line 613 and find:

	// development tool
	refEntity_t		testModelEntity;
	char			testModelName[MAX_QPATH];
	qboolean		testGun;

Add right under it:

	// inolen
	// is spec menu on?
	qboolean        specMenu;

Now go to about line 1261 and find:

qhandle_t CG_StatusHandle(int task);

Add this up under it:

// inolen
// Declare our functions
void CG_DrawSpecMenu( void );
void CG_SpecMenuCmd( int num );

Now go into cg_weapons.c and at about line 1393 find:

	num = atoi( CG_Argv( 1 ) );

Up under it add:

	// inolen
	// Leech user's input key
	if( cg.specMenu == qtrue ) {
		CG_SpecMenuCmd( num );
		return;
	}

Now its onto cg_draw.c to add in the last 2 bits of code, first lets add the little bit, then the huge bit :) So find:

if ( cg.snap->ps.persistant[PERS_TEAM] == TEAM_SPECTATOR ) {
		CG_DrawSpectator();
		CG_DrawCrosshair();
		CG_DrawCrosshairNames();

And up under it add:

		CG_DrawSpecMenu();

Now, for the core code! Go find:

/*
=================
CG_DrawVote
=================
*/

And directly ABOVE it add:

If you are a newbie to programming,
this is quite a bit of code to take in.
I have documented this code pretty well,
so I would suggest reading it.
