How do I display a menu in a module?

Geesu · **Author**

Basically ask the question asks, if I try UTIL_ShowMenu, I get an identifier not found...

Is there another way?

Also, after I display the menu, how can I catch the result?

Thanks,
Josh

Get the UTIL_ShowMenu from AMXX / HLSdk ;)

You have to catch the menuselect commands. If the user presses 2, you get:

menuselect 2

Or something.

so I won't know if the user like opens my menu... then say presses the button for the radio button, will I still get the same result?

OK I thought I had it working but I get an error on the following line:

Code:

void UTIL_ShowMenu( edict_t* pEdict, int slots, int time, char *menu, int mlen )
{
    char *n = menu;
    char c = 0;
    int a;
    if (!gmsgShowMenu)
        return;                         // some games don't support ShowMenu (Firearms)

    while ( *n ) {
        a = mlen;
        if ( a > 175 ) a = 175;
        mlen -= a;
        c = *(n+=a);
        *n = 0;                                     <<<<< Crashes here
        MESSAGE_BEGIN( MSG_ONE , gmsgShowMenu, NULL, pEdict );
        WRITE_SHORT( slots );
        WRITE_CHAR( time );
        WRITE_BYTE( c ? TRUE : FALSE);
        WRITE_STRING( menu );
        MESSAGE_END();
        *n = c;
        menu = n;
    }
}

I invoke it with:

Code:

    char *pimp = " Yo YO YO\n\0";

    UTIL_ShowMenu(pEntity, (0<<1), -1, pimp, (int)strlen(pimp));

Any suggestions?

delete the '\0' from your code.
if u write it in quotes, then it has automatically an '\0'.

in your pimp array u will see this:

Code:

 
char *pimp = { ' ', 'Y', 'o', ' ', 'Y',  'O', ' ', 'Y',  'O', '\n', '\0', '\0' };

You see, that u have 2 '\0'. Ok it costs only 1 byte more of RAM, but if u have to code on things like an micromaster, there you dont have much of ram^^.

so just write:

Code:

    char *pimp = " Yo YO YO\n";
