Anti God-mode problem - ]Rafaellos[ - 26.01.2013

Hello everyone, i am trying these days to create an anti god-mode for my Server.
My problem is not comparing right, so it detects non god-mode users.

My Code:

PHP код:
new Float:health_a,Float:health_b, Float:health_c;
public OnPlayerUpdate(playerid)
{
    GetPlayerHealth(playerid,health_a); //getting and saving players hp on health_a
    return 1;
}
public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid)
{
    health_c = health_a - amount; //minus the amount of damage from previous player health and saving it on health_c
    GetPlayerHealth(playerid,health_b);//getting the current player health
    if(health_c <= health_b)//checking if current health is equals or larger than the previous hp
    {
        if (GetPlayerVirtualWorld(playerid)==1)//checking the world (using different worlds from normal playing and deathmatch)
        {
            if(!IsPlayerLuxAdminLevel(playerid,10))//if player is not admin level 10
            {
                new pname[MAX_PLAYER_NAME];
                new string[170];
                GetPlayerName(playerid, pname, sizeof(pname));
                format(string, sizeof(string), "%s(%d) tried to GOD-Mode in dm/minigun.", pname, playerid);
                MessageToAdmins(-1,string);
                ResetPlayerWeapons(playerid);
                SetPlayerHealth(playerid, 100);
                SetPlayerVirtualWorld(playerid, 0);
                SetPlayerPos(playerid,-1670.1058,1303.2300,7.1820);
                SetCameraBehindPlayer(playerid);
                SendClientMessage(playerid, -1 , "Health Cheat detected, you have been automaticly teleported to spawn.");
                return 1;
            }
        }
    }
    return 1;
} 
Can anyone help me?

AW: Anti God-mode problem - Skimmer - 26.01.2013

I don't know why you use GetPlayerHealth function below OnPlayerUpdate.
OnPlayerUpdate gets called 60 times in a second. That means if someone take your health damage, the server will save in the variable health_a, the current health, after you got damaged.

Re: Anti God-mode problem - ]Rafaellos[ - 26.01.2013

Then how i can get and save the previous health so i can compare it??

Re: Anti God-mode problem - Patrick - 26.01.2013

simple tip: i tried on my server making a health anti what i did is

pawn Код:
public OnPlayerConnect
{
SetPlayerHealth(playerid, 99.99);//just incase to avoid bug
return 1;
}
public OnPlayerSpawn
{
SetPlayerHealth(playerid, 99.99);// there is no any changes at your health bar
return 1;
}
if you still got all things that has SetPlayerHealth(playerid, 100); change it to SetPlayerHealth(playerid, 99.99);

and when you detect it as a hacker
GetPlayerHealth(playerid, 100);
hope you understand it

also you need to remove the things that gives you health on default samp here

pawn Код:
public OnPlayerConnect
{
    RemoveBuildingForPlayer(playerid, 1302, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 1209, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 955, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 956, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 1775, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 1776, 0.0, 0.0, 0.0, 6000.0);
    RemoveBuildingForPlayer(playerid, 1977, 0.0, 0.0, 0.0, 6000.0);
    return 1;
}

I already did that, but s0.beit is lock on current hp, so if player use god on s0.beit, will have 99.

Thats why i am trying to compare health, so i can detect s0.beit users.

Re: Anti God-mode problem - Patrick - 26.01.2013

you could try SetPlayerHealth(playerid,98.99); if it damage alot on health bar, i cant think any idea of how to detect it.

Re: Anti God-mode problem - ]Rafaellos[ - 26.01.2013

Comparing is the only way to detect this types of god-mode...

Re: Anti God-mode problem - ]Rafaellos[ - 27.01.2013

Hi again, due to MouseBreaker information about OnPlayerUpdate, i decided to add a timer, that will check each second player's HP.

so i did:

PHP код:
new Float:health_a,Float:health_b;
new timer1;
forward HealthUpdate();
public OnFilterScriptInit()
{
    print("\n--------------------------------------");
    print(" Anti Cheats - LOADED");
    print("--------------------------------------\n");
    
    timer1 = SetTimer("HealthUpdate", 1000, 1);
    return 1;
}
public HealthUpdate()
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        GetPlayerHealth(i,health_a);
    }
    return 1;
}
public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid)
{
    KillTimer(timer1);
    GetPlayerHealth(playerid,health_b);
    if(health_a >= health_b)
    {
        if (GetPlayerVirtualWorld(playerid)==1)
        {
            if(!IsPlayerLuxAdminLevel(playerid,10))
            {
                new pname[MAX_PLAYER_NAME];
                new string[170];
                GetPlayerName(playerid, pname, sizeof(pname));
                format(string, sizeof(string), "%s(%d) tried to GOD-Mode in dm/minigun.", pname, playerid);
                MessageToAdmins(-1,string);
                ResetPlayerWeapons(playerid);
                SetPlayerHealth(playerid, 100);
                SetPlayerVirtualWorld(playerid, 0);
                SetPlayerPos(playerid,-1670.1058,1303.2300,7.1820);
                SetCameraBehindPlayer(playerid);
                SendClientMessage(playerid, -1 , "God-Mode detected, you have been automaticly teleported to spawn.");
                return 1;
            }
        }
    }
    timer1 = SetTimer("HealthUpdate", 1000, 1);
    return 1;
} 
But still the same problem. Please can anyone help me on this?

Re: Anti God-mode problem - Threshold - 27.01.2013

This should work:

pawn Код:
new Float:health_a[MAX_PLAYERS]; 
new Float:health_b;
forward HealthUpdate(); 

public OnFilterScriptInit() 
{ 
    SetTimer("HealthUpdate", 2000, 1); 
    return 1; 
} 

public HealthUpdate() 
{ 
    for(new i = 0; i < MAX_PLAYERS; i++) 
    { 
        if(IsPlayerConnected(i))
        {
            GetPlayerHealth(i, health_b); 
            if(health_b > health_a[i])
            {
                if(GetPlayerVirtualWorld(i) == 1) 
                { 
                    if(!IsPlayerLuxAdminLevel(i,10)) 
                    { 
                        new pname[MAX_PLAYER_NAME]; 
                        new string[65]; 
                        GetPlayerName(i, pname, sizeof(pname)); 
                        format(string, sizeof(string), "%s(%d) tried to GOD-Mode in dm/minigun.", pname, i); 
                        MessageToAdmins(-1,string); 
                        ResetPlayerWeapons(i); 
                        SpawnPlayer(i);
                        SendClientMessage(i, -1 , "God-Mode detected, you have been automatically teleported to spawn."); 
                        return 1;
                    } 
                } 
            }
            else 
            {
                health_a[i] = health_b;
            }
        }
    } 
    return 1; 
} 

public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid) 
{ 
    GetPlayerHealth(playerid,health_b); 
    health_a[playerid] = health_b;
    return 1; 
}
You needed to save the health_a variable to a playerid.
