How can I change the target of the tank when the survivor is incapacitated?

this is a bit of my code

PHP Code:

public void OnPluginStart()
{
    l4d_chance_attacknext = CreateConVar("l4d_chance_attacknext", "100.0", "chance of continue attack [0.0, 100.0]" );
    l4d_change_target = CreateConVar("l4d_change_target", "1", "0 = change target, 1 = change target");
    l4d_range_attack = CreateConVar("l4d_range_attack", "400.0", "attack range");

    HookEvent("player_incapacitated", eIncap);
}

public Action eIncap(Event event, const char[] name, bool dontBroadcast)
{ 
    int userid = event.GetInt("userid");
    int victim = GetClientOfUserId(userid);
    int tank = event.GetInt("attackerentid");
    if( victim > 0 && tank > 0)
    {
        if(IsClientInGame(victim) && GetClientTeam(victim)==2)
        {
            StartAttack(tank, victim);
        }
    }
    return Plugin_Continue;     
}

void StartAttack(int tank, int victim)
{ 
    if(IsTank(tank) && GetRandomFloat(0.0, 100.0) < l4d_chance_attacknext.FloatValue)
    { 
        OnStart(tank, victim);
    } 
}

void OnStart(int ent, int victim)
{
    if(IsTank(ent))
    { 
        GetEntPropVector(ent, Prop_Send, "m_vecOrigin", fPos);
        if(GetConVarInt(l4d_change_target)==1) NextVictim = GetVictim( victim, fPos );
        else if(IsPlayerIncapped(victim))
        {
            NextVictim = victim;
        }
        if( NextVictim > 0 )
        {
            PrintToChatAll("next target is %N", NextVictim);
        }    
    }
}

int GetVictim(int except, float Tpos[3])
{
    float minDis = l4d_range_attack.FloatValue;
    float ePos[3];
    int selected = 0;
    for( int i = 1; i <= MaxClients; i++)
    {
        if( IsClientInGame(i) && GetClientTeam(i)==2 && IsPlayerAlive(i) && i!=except && !IsPlayerIncapped(i) )
        {
            GetClientAbsOrigin(i, ePos);
            float dis = GetVectorDistance(ePos, Tpos);
            if( dis <= minDis )
            {
                selected = i;
                minDis = dis;
            }
        }
    } 
    return selected;
}

bool IsPlayerIncapped(int client)
{
    if( client > 0 && client <= MaxClients && IsClientInGame(client) && GetClientTeam(client) == 2 && IsPlayerAlive(client) )
    {
        if (GetEntProp(client, Prop_Send, "m_isIncapacitated", 1))
            return true;
    }
    return false;
}

bool IsTank(int client)
{
    if( client > 0 && client <= MaxClients && IsClientInGame(client) && GetClientTeam(client) == 3 )
    {
        int class = GetEntProp(client, Prop_Send, "m_zombieClass");
        if( class == 5 )
            return true;
    }
    return false;
}

1.
Use tEntDev to compare props when tank attacks different targets to find appopriate prop name.
Then, maybe change it OnThink.

2. Kick tank and create new one (clone) and apply point_hurt OnSpawn.

3. Apply vec math OnPlayerRunCmd like it is done by Pan XiaoHai in Evil Witch plugin.
