I had an idea on how we could let the server know what the bounding boxes are for a block. We simply create a list of boundingboxes in the block handler. Here is kinda what I mean:
BlockHandler.h:

typedef std::vector<cBoundingBox> BoundingBoxes;

/// Returns a list of bounding boxes. For example a cauldron returns 5 because it has 5 faces that are solid but a full block returns 1
virtual BoundingBoxes & GetBoundingBoxes(Vector3i a_Pos);

BlockHandler.cpp:

cBlockHandler::BoundingBoxes & cBlockHandler::GetBoundingBoxes(Vector3i a_Pos)
{
	cBlockHandler::BoundingBoxes BBS;
	
	if (cBlockInfo::IsSolid(m_BlockType))
	{
		cBoundingBox BB(a_Pos, 1, 1);
		BBS.push_back(BB);
	}

	return BBS;
}

Then when the server needs to know if an entity is in a block it loops through the list and checks if the bounding boxes intersect with the bounding box of an entity. This method would be usefull for for example a cauldron since it's more like a hollow block.


EDIT:

Another idea is to let the blockhandler itself check if an entity is inside.
