How can I implement Depth-First Search in Unity?

To implement DFS in Unity, you can use a recursive function or a stack data structure. Which one would you prefer?

I think a recursive function would be easier. Can you show me an example?

Sure! Here's a simple example:

void DFS(Node node) {
    if (node == null) return;
    node.visited = true;
    foreach (var neighbor in node.neighbors) {
        if (!neighbor.visited) {
            DFS(neighbor);
        }
    }
}

This function marks the node as visited and recursively visits its unvisited neighbors.

What if I want to visualize the DFS process in Unity?

You can visualize it by changing the color of the nodes as they are visited. You can use Unity's Renderer component to change the material color.
