Hello everyone!

I'm just wondering how to use menus in these modules!
Would be great if someone can explain me...

I know that a menu is a sent message, but, the problem is, the function with the button the player is pressing, and many: ...
How to register that function, to hook the menu shown to player?

Thanks in advance!

Why you don't look at the amxx source code ?

I want something better explained like a tutorial if possible.

I can show you a simple example to begin with.
plain menu, some codes from amxx
PS: C-style, I personally don't like c++ class style for doing this.

bool g_Is_CSDM_Menu = false;	//distinguish from other menus
void (*g_MENU_func)(int);	//your menu callback function
char menu[512];			//menu text

void show_menu(int keys)
{
	MESSAGE_BEGIN(MSG_ONE, MSGID_ShowMenu, NULL, pEdict_Jim);
	WRITE_SHORT(keys);
	WRITE_CHAR(-1);
	WRITE_BYTE(FALSE);
	WRITE_STRING(menu);
	MESSAGE_END();
}

void show_menu_advanced(int keys, int mlen)
{
	char *m = menu;
	char *n = menu;
	char c = 0;
	int a;

	while(*n)
	{
		a = mlen;
		if(a > 175)
			a = 175;
		mlen -= a;
		c = *(n+=a);
		*n = 0;
		
		MESSAGE_BEGIN(MSG_ONE, MSGID_ShowMenu, NULL, pEdict_Jim);
		WRITE_SHORT(keys);
		WRITE_CHAR(-1);
		WRITE_BYTE(c ? TRUE : FALSE);
		WRITE_STRING(m);
		MESSAGE_END();
		*n = c;
		m = n;
	}
}

//CSDM Main Menu
void csdm_menu_main()
{
	int keys = (KEY_1|KEY_2|KEY_3|KEY_4|KEY_5|KEY_6|KEY_7|KEY_8|KEY_9|KEY_0);
	int len  = sprintf(menu, "\\yCSDM Settings\n\n\
				 \\r1.\\w Players\n\
				 \\r2.\\w Maps\n\
				 \\r3.\\w Bots\n\
				 \\r4.\\w Game Modes\n\
				 \\r5.\\w Grenades\n\
				 \\r6.\\w Brightness\n\
				 \\r7.\\w Jim\n\
				 \\r8.\\w Time\n\
				 \\r9.\\w Spawn Editor\n\n\
				 \\r0.\\w Exit");

	show_menu_advanced(keys, len);

	g_Is_CSDM_Menu = true;
	g_MENU_func = csdm_menu_main_cmd;
}

void csdm_menu_main_cmd(int key)
{
	switch(key)
	{
	case 1:	csdm_menu_players();		break;
	case 2: csdm_menu_maps();			break;
	case 3: csdm_menu_bots();			break;
	case 4: csdm_menu_modes();			break;
	case 5: csdm_menu_grenades();		break;
	case 6: csdm_menu_brightness();		break;
	case 7: csdm_menu_jim();			break;
	case 8: cmd_csdm_time();			break;
	case 9: csdm_menu_spawn_editor();	break;
	}
}

//hook clientcommand
void C_ClientCommand(edict_t *pEntity)
{
	const char *cmd = CMD_ARGV(0);
	if( EQUAL(cmd, "menuselect") && pEntity == pEdict_Jim && g_Is_CSDM_Menu)
	{
		g_Is_CSDM_Menu = false;
		(*g_MENU_func)(atoi(CMD_ARGV(1)));
		RETURN_META(MRES_SUPERCEDE);
	}
	else
		RETURN_META(MRES_IGNORED);
	
	RETURN_META(MRES_IGNORED);
}

I think this is quite clear and self-explained, hope this helps.

what a clear code !
test and work fine !

[claudiuhks]

Of course, it works like a charm.
Thanks in advance, Jim.
