Alright, it is now properly fixed, and Silva can trigger earthquakes in GC6.

In gods.cpp:

void silva::PrayGoodEffect()
{

    // ...

  if(!game::GetCurrentLevel()->IsOnGround())
  {
    ADD_MESSAGE("Suddenly a horrible earthquake shakes the level.");
    int c, Tunnels = 2 + RAND() % 3;
    if (game::GetCurrentLevel()->GetLevelScript()->IsZombieLevel()) 
		Tunnels = 0;
   // ...
}

Created a quick fix for the bug that causes Silva to crash the game in GC6. Praying to Silva there will spawn wolves instead of starting an earthquake:

In gods.cpp:

void silva::PrayGoodEffect()
{

    // ...

  if(!game::GetCurrentLevel()->IsOnGround() && !game::GetCurrentLevel()->GetLevelScript()->IsZombieLevel())
  {
    ADD_MESSAGE("Suddenly a horrible earthquake shakes the level.");
    
   // ...
}

In script.h:

class levelscript : public scriptwithbase
{
  // ...
  SCRIPT_TRUTH_WITH_BASE(IsCatacomb);
  SCRIPT_MEMBER_WITH_BASE(festring, EnterImage);
  SCRIPT_MEMBER_WITH_BASE(v2, EnterTextDisplacement);
  SCRIPT_TRUTH_WITH_BASE(IsZombieLevel);
};

In script.cpp:

void levelscript::InitDataMap()
{
  // ...
  INIT_ENTRY(EnterTextDisplacement);
  INIT_ENTRY(IsZombieLevel);
}

In dungeon.dat:

 Level ZOMBIE_LEVEL;
  {
    Rooms = 1;
    IsZombieLevel = true;
    IgnoreDefaultSpecialSquares = true;
    MonsterAmountBase = 20;
    LOSModifier = 24;
    FillSquare = FLINT solidterrain(GROUND), GNEISS earth;
    //...
   }

Tomorrow I'll poke around and see if I can figure out why the earthquake causes the crash on that level (if anyone knows anything about this any info would be greatly appreciated), but failing that this should work nicely.

^Pepsi will also give you a slight perception boost, at the cost of your guruism.

I tried changing it to:

if(Victim && Terrorist)
	Terrorist->Hostility(Victim);

and it seems to work now. I'll do a bit more testing to make sure it works properly. I didn't push the last one to the repo (I don't think I have the power to push changes anyways).

This introduced a bug that caused the game to crash if the player stepped on a mine while carrying a gas grenade. I managed to fix it by altering

if(Victim)
	Terrorist->Hostility(Victim);

to

if(Victim && !Victim->IsPlayer())
	Terrorist->Hostility(Victim);

It will still crash if an NPC is hit by a mine-activated grenade, but the chances of that happening unintentionally are fairly low, so it shouldn't be too much of an issue. A more permanent solution would be not to set hostility in the case the grenade was activated by a mine (therefore no Terrorist to assign the hostility to), but that may be beyond my capabilities.

As I recall from another thread, in IVAN 0.40 (or one of the .4s; too lazy to check), you could dip containers and weapons into solid materials like flesh, but for whatever reason (likely what you said, 4zb4) it was removed in 0.50.

I also just realized that weeping blades in CVS spill acid on enemies; I never bothered using them before because they're always made of fairly weak materials.

I just found out that kneeling at an altar with '_' will give you a (very) slight increase in favor with that god.

Yeah, but it does it in the most charming way.

After years of being confused by it, and eventually just assuming it did nothing, I finally figured out what that "Be nice to pets?" option does in CVS... If you set it to 'no', and have a sadist weapon (whip/banana peel/bodyparts/etc) and your pet is a masochist, moving into them will ask "Do you want to punish them?" and if you say yes you'll hit them, instead of just displacing them like normal.

Not very useful it seems, but you can get some whip training in on the slave in Attnam if nothing else (wow... this sounds incredibly dark).

I used that link, but that gave me the initial problems. I'll pm you

EDIT: Thanks, it worked!
