How can I implement the A* algorithm in Unity?

To implement the A* algorithm in Unity, you'll need to create a grid system, define start and end nodes, and use a priority queue.

What data structures should I use for the open and closed lists?

You can use a List for the open list and a HashSet for the closed list to efficiently check for existing nodes.

How do I calculate the cost for each node?

The cost can be calculated using the G cost (distance from the start node), H cost (heuristic estimate to the end node), and F cost (G + H).

Can you give me a simple code example?

Sure! Here's a basic example:

public class Node {
    public int GCost;
    public int HCost;
    public Node Parent;
}
