[L4D2]About m_humanSpectatorUserID and the multiplayer plugin

sorallll · **Author**

Recently, when researching multiplayer plugins, I found a problem. After obtaining the m_humanSpectatorUserID of Survivor Bot and converting it to Client Index, they seem to judge IsClientInGame and others.

sorallll

But the player in the transition corresponding to the Bot is detected as true IsClientConnected and IsClientInGame detected as false, which will cause the Bot of some transition players to be taken over by others

sorallll

Maybe the player's equipment role after transition is messed up, and the multiplayer plug-in also has a certain reason

sorallll

This is the judgment of the game itself on taking over the Bot

PHP Code:


			
 if ( pSurvivorBot )

    {

        if ( !pSurvivorBot->SurvivorBot.m_humanSpectatorUserID

          || (v22 = CDirector::IsHumanSpectatorValid(pDirector, pSurvivorBot), result = 0, !v22) )

        {

            CDirector::NewPlayerPossessBot(a1, a2, v16, pDirector, pPlayer, pSurvivorBot_);

            result = 1;

        }

    } 



signed*int*__cdecl*CDirector::IsHumanSpectatorValid(CDirector**this,*SurvivorBot**a2)

{

****SurvivorBot**v2;*//*eax

****int*v3;*//*edi

****int*v4;*//*esi

****const*char**v5;*//*eax

****signed*int*result;*//*eax

****const*char**v7;*//*eax



****v2*=*UTIL_PlayerByUserId(a2->SurvivorBot.m_humanSpectatorUserID);

****{

********v3*=*a2->SurvivorBot.m_humanSpectatorUserID;

********v4*=*(v2->vptr->CBaseEntity.GetPlayerName)(v2);

********v5*=*SurvivorCharacterName(a2->SurvivorBot.CTerrorPlayer.m_survivorCharacter);

********DevMsg(1,*"[TAKEOVER]:*%s*is*already*spectated*by*%s*(%d)\n",*v5,*v4,*v3);

********result*=*1;

****}

****else

****{

********v7*=*SurvivorCharacterName(a2->SurvivorBot.CTerrorPlayer.m_survivorCharacter);

********DevMsg(1,*"[TAKEOVER]:*%s*is*spectated*by*an*invalid*userid*-*clearing*spectator*id.\n",*v7);

********RemoveTransitioningPlayerRecord(a2->SurvivorBot.m_humanSpectatorUserID);

********SurvivorBot::ResetHumanSpectator(a2);

********result*=*0;

****}

****return*result;

}*

This is by design, because when map ends all players are disconnected and connected again.
