    new headshot = read_data( 3 )
    new clip, ammo, weapon = get_user_weapon(attacker,clip,ammo);
 
    PlayerXP[attacker] += get_pcvar_num(XP_Kill)
 
    if(headshot)
    PlayerXP[attacker] += get_pcvar_num(XP_Hs)
 
    if(weapon == CSW_KNIFE)
    PlayerXP[attacker] += get_pcvar_num(XP_Knife)

public client_connect(id)

    {
 
        LoadData(id)

    }
    PlayerXP[id] = 0
}
public SaveData(id)
{
    new AuthID[35]
    get_user_authid(id,AuthID,34)
 
    new vaultkey[64],vaultdata[256]
    format(vaultkey,63,"%s-Mod",AuthID)
    format(vaultdata,255,"%i#%i#",PlayerXP[id])
    nvault_set(g_vault,vaultkey,vaultdata)
    return PLUGIN_CONTINUE
}
public LoadData(id)
{
    new AuthID[35]
    get_user_authid(id,AuthID,34)
 
    new vaultkey[64],vaultdata[256]
    format(vaultkey,63,"%s-Mod",AuthID)
    format(vaultdata,255,"%i#%i#",PlayerXP[id])
    nvault_get(g_vault,vaultkey,vaultdata,255)
 
    replace_all(vaultdata, 255, "#", " ")
 
    new playerxp[32]
