Yes, that should work. I have edited the plugin based upon following code: https://forums.alliedmods.net/showthread.php?t=163585

Try this:

PHP Code:

#include < amxmodx >
#include < amxmisc >
#include < fakemeta >
#include < hamsandwich >

#define IsPlayer(%1) (1<= %1 <= g_iMaxPlayers)
#define MAX_WEAPONS CSW_P90

#define MAX_PLAYERS 32

const bitsNotAllowedWeapons = 1 << CSW_SMOKEGRENADE | 1 << CSW_HEGRENADE | 1 << CSW_FLASHBANG | 1 << CSW_C4

new g_iMaxPlayers, bool: g_bHamRegistered, bool:bIsUserBot[ MAX_PLAYERS + 1 ]

new bool:g_weaponMortalHeadshot[ MAX_WEAPONS + 1 ]

public plugin_init()
{
    register_plugin( "Bot Headshot Chance", "0.1", "eXtrem / AMXX Community" )
    
    register_concmd( "bhc_chance", "ConsoleCommand_MortalHeadshot", ADMIN_KICK )

    if(!g_bHamRegistered)
    {
       g_bHamRegistered = true
       RegisterHamFromEntity( Ham_TraceAttack, id, "HamTraceAttack" )
     }
}

public client_disconnected(id)
{
    bIsUserBot[id] = false
}

public HamTraceAttack( victim, attacker, Float:damage, Float:tr[3], traceresult/*, dmgbits*/ )

    {
        set_tr2(traceresult, TR_iHitgroup, HIT_CHEST)

You can customize the weapons, which should have the effect. I have renamed the cvar name as you can see. The damage gets divided by 3, you may want to adjust that.

Ok, I have edited the code. It should now redirect a bot's headshot to the chest. You should never receive headshots by this now (not even the sound, since the actual hit gets redirected).

Good that you could figure it out with the task. I guess it will only work for bots. You should do the following:

1) Make the change you have written
2) Add in plugin_init() following:
RegisterHam(Ham_TraceAttack, "player", "HamTraceAttack")

This way noone will be able to make any headshots.

Glad I could be helpful. Shouldn't effect the performance much. It's safe to use.
