How to use cLineBlockTracer in cpp? I'm currently working on boats and I noticed that you can only spawn boats by looking at a block not at water. I'm currently using

class cLineBlockTracer :
	public cBlockTracer::cCallbacks
{
public:
	Vector3d Pos;
	virtual bool OnNextBlock(int a_BlockX, int a_BlockY, int a_BlockZ, BLOCKTYPE a_BlockType, NIBBLETYPE a_BlockMeta) override
	{
		if (a_BlockType != E_BLOCK_AIR)
		{
			Pos = Vector3d(a_BlockX, a_BlockY, a_BlockZ);
			return true;
		}
		return false
	}
} Callbacks;

but I get these errors:

Code:

1>g:\mcserver\nieuwste versie\trunk\src\items\ItemBoat.h(44) : error C3668: 'cItemBoatHandler::OnItemUse::cLineBlockTracer::OnNextBlock' : method with override specifier 'override' did not override any base class methods
1>g:\mcserver\nieuwste versie\trunk\src\items\ItemBoat.h(49) : error C2259: 'cItemBoatHandler::OnItemUse::cLineBlockTracer' : cannot instantiate abstract class

Wait I think I got it.

Yes I got it. The example in World.cpp was a little outdated.
