Let's assume I have a CEntity class that describes every entity within the game.

Each entity class has it's own std::vector of CActions. Each CAction is just an action that the entities can perform, for example CActionFight would have the logic for fighting.

To command my player (or any other entity) to fight all I do is:

CActionFight *pActionFight = new CActionFight();
pActionFight->SetTarget(pTargetEntity);
pPlayer->AddAction(pActionFight);

Before this action is started, all other actions queued earlier have to be finished. Imagine player starting to execute the CActionFight over pTargetEntity and suddenly, pTargetEntity disconnects. pTargetEntity is invalid and here's my question.

How do you normally handle that in actions?

If a disconnection event of an entity is received on the server side, do you iterate through the actions of all entity in the map and remove these which are related to an entity that has just dropped connection?

EDIT Liked Josh's approach and implemented the solution, sounds very sensible and worked like a charm.

// Example of an action, checking wether Entity is still valid.
void CActionFight::Execute()
{
    m_iCycles--;
    
    if(m_iCycles>0)
    {
        if(m_pTarget->IsValid() == false)
        {
            m_pTarget = NULL;
            m_bValid = false;
        }
        else
        {
            printf("Attacking.%s\n", m_pTarget->GetName().data());
        }
    }
    else m_bValid = false;
}

Ok i've read couple of these so far on gd stackexchange, but i would like to sum up the approach.

Lets assume i have an CEntity class(this is simplified), that describes every entity within the game. Each Entity class has it's own std::vector of CActions. Each CAction is nothing more than an action that the Entities can perform, for example

CActionFight - would have the logic for fighting (script)

So in order to command my player or any other entity to fight all i do is:

CActionFight *pActionFight = new CActionFight();
pActionFight->SetTarget(pTargetEntity);
pPlayer->AddAction(pActionFight);

Before this action is started, all other actions queued earlier have to be finished (that's for now).

  Imagine player starting to execute the CActionFight over pTargetEntity and suddenly, pTargetEntity disconnects.

pTargetEntity is invalid and here's the question.
