Placeholder object instance;

[Code Apperentice]

Hey guys, I'm trying to solve an A* pathfinding problem, I've ran into a problem where I can't set a placeholder object to get filled in the constructor later

class Node{
public:
	int coordX;
	int coordY;
	Node parent;
	int distFromStart;
	int heuristicDistFromTarget;
	int totalCost;
	Node(int, int, Node, int, int);
};

Node::Node(int mX, int mY, Node mParent, int dStart, int hDTarget){
	coordX = mX;
	coordY = mY;
	parent = mParent;
	distFromStart = dStart;
	heuristicDistFromTarget = hDTarget;
	totalCost = dStart + hDTarget;
}

When I set Node parent it won't let me, it says "Incomplete type not allowed". Any suggestions?

You can't have a Node contain another Node like that. Just imagine how big the node object would have to be. The node contains a node which contains another node which contains yet another node, and so on. The object would have to be infinitely big.

Consider using a pointer to the parent node instead.

Ah thanks, I just made parent a list of Nodes and pushback into it in the constructor
