- sv_antihack_ban_minutes // Ban time (minute) | Default: 10

- I knew there are a lot of anti hack plugin...

because no one can run 250m per a second

with scout your speed is 260.

[dias]

250 is not player speed. That is the distance from old origin and new origin

What if the player has a lot of lag ?

[dias]

example ?

For the ping lag, you can try this:

Cvar: amx_antihack_min_ping - 100

#include <amxmodx>
#include <engine>
#include <fakemeta>

new Float:g_lastcheck[33], Float:g_lastcheck2[33]
new Float:g_cur_origin[33][3]
new Float:g_vic_origin[33][3]

new antihack_active
new cvar_antispeed, cvar_antispeed_code, cvar_ban_minutes, cvar_min_ping

public plugin_init()
{
    register_plugin("AntiHack Speed", "1.0", "Dias")
    
    register_event("HLTV", "event_newround", "a", "1=0", "2=0")
    register_logevent("event_round_end", 2, "1=Round_End")
    register_event("TextMsg","event_round_end","a","2=#Game_Commencing","2=#Game_will_restart_in")
    
    cvar_antispeed = register_cvar("sv_antihack_speed", "1")
    cvar_antispeed_code = register_cvar("sv_antihack_speed_code", "250.0")
    cvar_ban_minutes = register_cvar("sv_antihack_ban_minutes", "10")
    cvar_min_ping = register_cvar("amx_antihack_min_ping", "100")
}

public plugin_cfg()
{
    set_task(1.0, "event_newround")
}

public event_newround(id)
{
    set_task(1.0, "active_antihack", id)
}

public event_round_end(id)
{
    antihack_active = 0
}

public active_antihack(id)
{
    antihack_active = 1
    g_vic_origin[id] = g_cur_origin[id]
}

public client_PostThink(id)
{
    if(is_user_alive(id) && antihack_active && get_pcvar_num(cvar_antispeed))
    {
        static Float:Current_Time
        Current_Time = get_gametime()
        
        if(Current_Time - 0.5 > g_lastcheck[id])
        {
            pev(id, pev_origin, g_cur_origin[id])
            g_lastcheck[id] = Current_Time
        }
        
        if(Current_Time - 1.0 > g_lastcheck2[id])
        {
            check_origin(id)
            g_lastcheck2[id] = Current_Time
        }   
    }
}

public check_origin(id)
{
    static Float:distance
    
    pev(id, pev_origin, g_vic_origin[id])
    distance = get_distance_f(g_cur_origin[id], g_vic_origin[id])

    if(distance > get_pcvar_float(cvar_antispeed_code) && pev(id, pev_flags) & FL_ONGROUND)
    {
        new Ping, Loss
        get_user_ping(id, Ping, Loss)
        
        if(Ping >= cvar_min_ping)
            return;
        
        static name[32]
        get_user_name(id, name, sizeof(name))
        
        server_cmd("amx_banip %s %s Hack_Speed_Detect", get_pcvar_num(cvar_ban_minutes), name)
    }
}

I suggest you to change this plugin's punishment to slay.

If a player slayed three times or more, the plugin will make a vote for all players to vote ban the cheater.

Another question, I am running a zombie plague server. Should I change the sv_antihack_speed_code value to the fastest zombie's speed value?

Does your plugin will ban the player who use the vehicle make a larger than sv_antihack_speed_code distance?

Why don't enable VAC?

If I have 500 speed (set by a plugin) this plugin ban me ? (i have a superhero server)

good plugin =)
