Find nearest reachable Node with specific tag

Hi

You can do that with the MultiTargetPath, however since the number of nodes with a specific tag is probably a very high number I would recommend that you use a slightly custom XPath instead. XPath is essentially like ABPath but you can set a custom ending condition. I recommend that you do something like

public class TagEndingCondition : PathEndingCondition {
	public int tag;

	public TagEndingCondition (int tag) {
		this.tag = tag;
	}

	public override bool TargetFound (PathNode node) {
		return node.Tag == tag;
	}
}

And call it like

 // Start the path without the same end point as start point because we don't really have a clear end point in this case
 var path = XPath.Construct(start, start, null);
 // Search outwards, not towards the end point
 path.heuristic = Heuristic.None;
 path.endingCondition = new TagEndingCondition(2 /* (or whatever) */);
 seeker.StartPath(path, OnPathComplete);
