I think it's a ripoff system anyway... Committers get 1percent of deposited coins, which means they keep 99pct. So for each project they will always keep the biggest part of the coins :/

It seems that the loop is not working - the BTC is gone from me, but it's not been added to the project. What a black hole! >=[

How strange. There's a forum post on the bitcoin forums where you could complain I think.

Here it is.

I'm trying to make other wolves attack players when a wolf is attacked by a player, but I need to convert an cEntity to an cMonster in order to use GetMobType(). This is the code I use:

class cCallback :
	public cEntityCallback
{
	virtual bool Item(cEntity * a_Entity) override
	{
		if (a_Entity->IsMob())
		{
			if (a_Entity->GetMobType() == cMonster::mtWolf)
			{
				double Distance = (a_Entity->GetPosition() - ThisWolfPos).Length();
				if (Distance < 20)
				{
				}
			}
		}
		return false;
	}
public:
	Vector3f ThisWolfPos = GetPosition();
} Callback; Callback;

Try something like:

Code:

((const cMonster &)a_Entity).GetMobType()

You missed a * in there, it's a pointer.

Y think you can check mob type directly in cEntity. Use Entity:GetClass(). It returns cPickup and entity tipe but if its a mob it returns cWolf, cCreeper...

I tried registering there, but it didn't work - it said my password is too short and when I tried again, it said I'm already registered, but the login didn't work and registering for a different account said I need to wait 45 minutes. Not gonna bother anymore.

Not good - that's comparing strings, which is order of magnitude slower than comparing enums, even with the double step.

Probably the best code to check if an entity is a specific mob type currently is (if a_Entity is a cEntity *):

if (a_Entity->IsMob() && (((cMonster *)a_Entity)->GetMonsterType() == cMonster::mtWolf))

or if a_Entity is a const cEntity &, then:

if (a_Entity.IsMob() && (((const cMonster &)a_Entity).GetMonsterType() == cMonster::mtWolf))

That works, Now I need to have a variable with the current wolfs coordinates and the Players cEntity object in the callback. Any idea how to do that?

Don't wolves attack *all* players when they are aggravated? So just flipping their "IsAngry" flag should be enough.

I expect a code like this should work (written from the top of my head, may not compile):

function cWolf::DoTakeDamage(TakeDamageInfo & a_TDI)
{
  super:DoTakeDamage(a_TDI);
  if (m_IsTame)
  {
    // No aggravating for tame wolves
    return;
  }
  if (a_TDI.DamageType != dtAttack)
  {
    // Not attacked by a player, bail out
    // TODO: projectiles use dtRangedAttack with a projectile entity in the Attacker field, handle that too
    return;
  }

  ASSERT(a_TDI.Attacker != NULL);
  class cCallback : public cEntityCallback
  {
  public:
    Vector3f m_AttackerPos;

    cCallback(const Vector3f & a_AttackerPos) : m_AttackerPos(a_AttackerPos) {}

    virtual bool OnEntity(cEntity & a_Entity) override
    {
      // AGGRAVATE_RANGE is the range in blocks in which the wolves become angry; define that constant at the top of Wolf.cpp as static const double
      if (a_Entity.IsMob() && (((cMonster &)a_Entity).GetMobType() == mtWolf) && ((a_Entity.GetPos() - m_AttackerPos).SqrLength() < AGGRAVATE_RANGE * AGGRAVATE_RANGE))
      {
        ((cWolf &)a_Entity).SetAngry(true);
      }
      return false;
    }
  } Callback(a_TDI.Attacker.GetPos());
  m_World->ForEachEntity(Callback);
}

A little deviantion from redstone again: I need halp too, this time on saving mobs

// This code crashes:

void cWSSAnvil::LoadSlimeFromNBT(cEntityList & a_Entities, const cParsedNBT & a_NBT, int a_TagIdx)
{
	int SizeIdx = a_NBT.FindChildByName(a_TagIdx, "Size");

	if (SizeIdx < 0) { return; }

	int Size = a_NBT.GetInt(SizeIdx);

	cMonster * Monster = NULL;
	Monster = new cSlime(Size);
	if (!LoadEntityBaseFromNBT(((cEntity &)Monster), a_NBT, a_TagIdx))
	{
		return;
	}

	a_Entities.push_back(Monster);
}

//////////////////////////
// This code does too (with a deadlock):

void cWSSAnvil::LoadSkeletonFromNBT(cEntityList & a_Entities, const cParsedNBT & a_NBT, int a_TagIdx)
{
	int TypeIdx = a_NBT.FindChildByName(a_TagIdx, "SkeletonType");

	if (TypeIdx < 0) { return; }

	bool Type = ((a_NBT.GetByte(TypeIdx) == 1) ? true : false);

	std::auto_ptr<cSkeleton> Monster(new cSkeleton(Type));
	if (!LoadEntityBaseFromNBT(*Monster.get(), a_NBT, a_TagIdx))
	{
		return;
	}

	a_Entities.push_back(Monster.release());
}

What exactly should I do here to make mobs spawn?
