How do I add a working grenade?

[mindcore]

Hey Emergency Planet.

I am trying to make a submod for Hoppah's Los Angeles Mod 2.1.

I have very little experience with scripting in Emergency 4 (although I do know some C++).

I am trying to add a new command to soldiers: Get Grenade. I pretty much want to make a copy of the flashbang but make it explosive, and make a secondary command to retrieve and use it.

This is for a military submod I am making... I'm not a trigger-happy maniac.

Any ideas? As I am a complete newbie, I really need all the help I can get. My code so far is:

object ThrowMolotov : CommandScript
{
ThrowMolotov()
{
  SetValidTargets(ACTOR_FLOOR | ACTOR_OBJECT | ACTOR_VIRTUAL | ACTOR_HOUSE | ACTOR_OPEN_HOUSE);
  SetPossibleCallers(ACTOR_PERSON);
  SetIcon("throwmolotov");
  SetCursor("throwmolotov");
}
bool CheckPossible(GameObject *Caller)
{
  if(!Caller->IsValid() || Caller->GetType() != ACTOR_PERSON || Caller->GetEquipment()!=EQUIP_BOTTLE)
   return false;
  return true;
}

bool CheckTarget(GameObject *Caller, Actor *Target, int childID)
{
  if(!Caller->IsValid() || Caller->GetEquipment()!=EQUIP_BOTTLE || Caller->GetID() == Target->GetID())
   return false;
  if (Caller->GetType() != ACTOR_PERSON)
   return false;
  Person p(Caller);
  if(p.GetEnteredCarID() != -1)
   return false;
  return true;
}

void PushActions(GameObject *Caller, Actor *Target, int childID)
{
  Vector CmdPos, TargetPos;
  CmdPos = Game::GetCommandPos();
  TargetPos = CmdPos;

  Person p(Caller);
  if(!p.IsValid())
   return;
  if (p.GetThrowPosition(TargetPos))
  {
   Caller->PushActionmove(ACTION_NEWLIST, TargetPos);
   Caller->PushActionTurnTo(ACTION_APPEND, CmdPos);
  }
  else
  {
   Caller->PushActionTurnTo(ACTION_NEWLIST, CmdPos);
  }
  Caller->PushActionThrowMolotov(ACTION_APPEND, CmdPos, 150000.f);
  Caller->PushActionRemoveEquipment(ACTION_APPEND); 
}
};

object GetMolotov : CommandScript
{
GetMolotov()
{
  SetValidTargets(ACTOR_FLOOR | ACTOR_OBJECT | ACTOR_VIRTUAL | ACTOR_HOUSE | ACTOR_OPEN_HOUSE);
  SetGroupID(CGROUP_GETEQUIPMENT);
  SetPossibleCallers(ACTOR_PERSON);
  SetNeedsCarWithFlagSet(OF_HAS_FLASHGRENADE);
  SetIcon("getmolotov");
  SetCursor("getmolotov");
}
bool CheckTarget(GameObject *Caller, Actor *Target, int childID)
{
   if (!Caller->IsValid() || !Target->IsValid() || (Caller->GetID()==Target->GetID()))
    return false;
   if (Target->GetType()==ACTOR_VEHICLE)
   {
    Vehicle v(Target);
    if ((v.HasCommand("FlyTo") || v.HasCommand("VcmdDeInstallRope")) && !v.IsOnGround())
     return false;
   }

   Person p(Caller);
   if(p.IsValid() && (p.IsCarryingPerson()||p.IsLinkedWithPerson()|| p.IsPulling() || p.GetEnteredCarID() != -1))
    return false;

   GameObject obj(Target);
   if (Caller->GetObjectType()==TYPE_PERSON && Caller->GetEquipment()!=EQUIP_FLASHGRENADE &&
    obj.IsValid() && obj.IsFlagSet(OF_HAS_FLASHGRENADE))
   {
    return true;
   }

   return true;
}
void PushActions(GameObject *Caller, Actor *Target, int childID)
{
  Vector TargetPos = Target->GetTargetPoint(Caller, TARGET_EQUIPMENTDOOR);

  Caller->PushActionmove(ACTION_NEWLIST, TargetPos);
  Caller->PushActionTurnTo(ACTION_APPEND, Target);
  Caller->PushActionGetEquipment(ACTION_APPEND, Target, EQUIP_BOTTLE);
}
};

I will give Hoppah a hint about it, maybe he has an idea

[Rlast]

Just out of interest, have you created a model to go with it or are you just going to edit the properties of the flashbang?

[Newfoundking]

That's what I was thinking too, essentially create a new flashbang but instead of it exploding and disorienting people, have people in XYZ dustance injured by fire, and give it the other properties of an explosion.

I think the retrieving and using function though would be a little foolhardy

[mindcore]

Yes, you are probably right. I just have no idea what I am doing, so I used the first (and only) example script I could find!

[Rlast]

Made this model as a tester if it's of any interest to you; I'm not even sure if you wanted an explosive grenade, but what the heck', someone might .

[Miercolini]

Not sure if this will help, but during those riots they sometime throw Molotov. Not sure if they helps.

[Hoppah]

In addition to Voodoo, it should be possible by using a modified version of the flashbang script.

You cannot edit the flashbang code itself to make it injure or kill people as that code can only stun persons within a certain range.

I suggest you modify the Flashbang-script though and make it spawn an invisible object on the location where the flashgrenade is thrown (CmdPos).

Make the spawned object explode and voilá you will have something that looks like an exploding grenade.

The only problem you might encounter, is the timing of the explosion, but I'm sure thats resolvable too.

Don't forgot to change the Explosion Effect in the editor (Edit Traits menu) to an 'explosion type' of your choice, like 'explosioncar01'.

Also, change the 'material setting' of the invisible object in the editor. If I recall correctly, the material is related to the force of the explosion.

I'm not sure if the ThrowMolotov code will work. I've never used that code.

Good luck,

Mr Hop

Thanks for all the responses! I will try what you guys have said and see what I can get working.
