handle all NPC, even when no player has is proximity

[illift]

Hi,
I am currently developing a custom battleground in mangos.
In this battleground, I have a script with scriptdev2 creature that has spawn interval regulate other NPC.

The problem I have is that when are too far away from the NPC, the server uses the "pause" in some way and so he stopped to invoke.

I tried to increase visibility in the configuration file but it is still too little.

Anyone know what part of it I can modify the source code for the server to handle all NPC in the battleground, even when no player has is proximity?

Sorry for my bad English.

Thank you for reading.

The problem is npc's are only loaded when players go near them.

You have to manually change the load distance (static spawns) by rewriting how it is handled in the core, or handle events not from a npc.

Thank you for your response,
That's what I thought, I already try to change several different location in the core but I can not found the piece of code that handles this.

I thought the following code, tell me if I'm wrong:

In map.cpp line 1120 (in my core)

void Map::AddToActive( WorldObject* obj )
{
m_activeNonPlayers.insert(obj);
Cell cell = Cell(MaNGOS::ComputeCellPair(obj->GetPositionX(), obj->GetPositionY()));
EnsureGridLoaded(cell);

// also not allow unloading spawn grid to prevent creating creature clone at load
if (obj->GetTypeId() == TYPEID_UNIT)
{
Creature* c= (Creature*)obj;

if (!c->IsPet() && c->HasStaticDBSpawnData())
{
float x,y,z;
c->GetRespawnCoord(x,y,z);
GridPair p = MaNGOS::ComputeGridPair(x, y);
if(getNGrid(p.x_coord, p.y_coord))
getNGrid(p.x_coord, p.y_coord)->incUnloadActiveLock();
else
{
GridPair p2 = MaNGOS::ComputeGridPair(c->GetPositionX(), c->GetPositionY());
sLog.outError("Active creature (GUID: %u Entry: %u) added to grid[%u,%u] but spawn grid[%u,%u] not loaded.",
c->GetGUIDLow(), c->GetEntry(), p.x_coord, p.y_coord, p2.x_coord, p2.y_coord);
}
}
}
}

void Map::RemoveFromActive( WorldObject* obj )
{
// Map::Update for active object in proccess
if(m_activeNonPlayersIter != m_activeNonPlayers.end())
{
ActiveNonPlayers::iterator itr = m_activeNonPlayers.find(obj);
if(itr==m_activeNonPlayersIter)
++m_activeNonPlayersIter;
m_activeNonPlayers.erase(itr);
}
else
m_activeNonPlayers.erase(obj);

// also allow unloading spawn grid
if (obj->GetTypeId()==TYPEID_UNIT)
{
Creature* c= (Creature*)obj;

if(!c->IsPet() && c->HasStaticDBSpawnData())
{
float x,y,z;
c->GetRespawnCoord(x,y,z);
GridPair p = MaNGOS::ComputeGridPair(x, y);
if(getNGrid(p.x_coord, p.y_coord))
getNGrid(p.x_coord, p.y_coord)->decUnloadActiveLock();
else
{
GridPair p2 = MaNGOS::ComputeGridPair(c->GetPositionX(), c->GetPositionY());
sLog.outError("Active creature (GUID: %u Entry: %u) removed from grid[%u,%u] but spawn grid[%u,%u] not loaded.",
c->GetGUIDLow(), c->GetEntry(), p.x_coord, p.y_coord, p2.x_coord, p2.y_coord);
}
}
}
}

I think this is called "grid"? And grud unload timer could be increased i guess

I honestly have no idea how it is handled, nor where. Your best bet would be to ask the developers of the core.
