release Check Safe Zone For Monster Fix

[Black_Rose©]

 

Hey everyone,

Here is a quick and effective server-side modification to prevent players from luring aggressive monsters into towns or designated safe zones. This script continuously checks the monster's coordinates, and if it steps into a "No-PK" / safe attribute zone, it is instantly and safely removed from the map.

Below are the step-by-step changes required in your source code.

📂 Step 1: Open game\src\char.h

First, we need to declare the new function. Look for your public section and add the following line:

C++

void CheckSafeZoneForMonster();

📂 Step 2: Open game\src\char.cpp

Next, we will implement the actual logic. You can add this block anywhere within the global namespace area of the file:

C++

void CHARACTER::CheckSafeZoneForMonster()
{
if (!IsMonster())
return;

if (IsDead())
return;

LPSECTREE sectree = GetSectree();
if (!sectree)
return;

if (sectree->IsAttr(GetX(), GetY(), ATTR_BANPK))
{
M2_DESTROY_CHARACTER(this);
return;
}
}

📂 Step 3: Update the State Machine in game\src\char.cpp

Finally, we need to make sure the server triggers this check regularly. Find your UpdateStateMachine function and modify it to include our new check, exactly like this:

C++

void CHARACTER::UpdateStateMachine(DWORD dwPulse)
{
if (dwPulse < m_dwNextStatePulse)
return;

if (IsDead())
return;

CheckSafeZoneForMonster();

if (IsDead())
return;

Update();
m_dwNextStatePulse = dwPulse + m_dwStateDuration;
}

✨ And that's it! Recompile your game source, and monsters will no longer be able to invade your safe zones.
