SMAC null cmd explanation.

Hi.

I'm interested to know what the reason is behind blocking null cmd input in OnClientRunCmd. Does anyone from the smac team remember why this code is in here. Is it possibly just a typo and it's ment to return Plugin_Continue ?

smac_eyetest.sp ->

This;

Code:

        // NULL commands

        if (cmdnum <= 0)

                return Plugin_Handled;

Re: SMAC null cmd explanation.

Formerly, the seed for weapon spread was calculated as seed=MD5_PseudoRandom(cmdnum). Not blocking cmdnum=0 causes a static seed to be easily accessible. Meaning, cheats wouldn't need to brute force this seed by skipping future cmdnums. IIRC, cmdnum=0 is useless and typically caused by clients typing "disconnect" in console.
