i have do something like this.

PHP Code:

int cheat_client = -1;
for(int i = 1; i <= MaxClients; i++) 
{ 
    if(IsClientInGame(i))
    {
         cheat_client = i;
         break;
     }
}
if( !L4D_GetRandomPZSpawnPosition(cheat_client,class,5,{0.0,0.0,0.0}) )//这个玩家附近的位置, 类型, 次数, 无用的vec
{
    LogMessage("找位失败, 正在重新找位.");
    CreateTimer(1.0,Timer_CreateInfectedBotByClass,class,TIMER_FLAG_NO_MAPCHANGE);
    return;
}

int bot = CreateFakeClient("Infected Bot");
if( bot != 0 )
{
    ChangeClientTeam(bot,TEAM_INFECTED);
    KickClient(bot);
    switch(class)
    {
        case CLASS_CHARGER: 
        CheatCommand(cheat_client, "z_spawn_old", "charger auto");
        case CLASS_HUNTER: 
        CheatCommand(cheat_client, "z_spawn_old", "hunter auto");
        case CLASS_JOCKEY: 
        CheatCommand(cheat_client, "z_spawn_old", "jockey auto");
        case CLASS_SMOKER: 
        CheatCommand(cheat_client, "z_spawn_old", "smoker auto");
        case CLASS_BOOMER: 
        CheatCommand(cheat_client, "z_spawn_old", "boomer auto");
        case CLASS_SPITTER: 
        CheatCommand(cheat_client, "z_spawn_old", "spitter auto");
    }
} 


It prevent most of the issue about "couldn't find position", but sometime it happend again.
I guess that maybe check position before spawn is not perfect. Harry said that CreateFakeClient is too expensive, and usually late out in tick.

I look up some .sp file about infected_bot_control, they use SDKCall(NextBotxxxxxxx) to spawn infectedbot, and use the return value of SDKCall to check whether it spawn correctly. But "z_spawn_old" cmd has no return value.

I think DHook z_spawn_old(const CCommand *) , get and check the return value will help, but i don't know how to do this because it return a warning() func in failed and i don't know which type of return is appropriate.

Can someone give a suggestion?
