Accessing previous node in TraversalProvider

Feature Requests
1

Hi! I don’t think it is possible so I am writing in Feature Requests. It would be awesome to be able to access the previous node while making additional checks with TraversalProvider (for example when making sure that there is a connection between individual nodes for bigger size agents).

also I’ve tried to access Path as it should be provided in the traversal methods, i.e.

bool CanTraverse (Path path, GraphNode node);

But it does not contain any nodes.

I am using it with LayeredGridGraph with beta 4.3.26

@aron_granberg could you please take a look at this?

U need to change pathHandler to public in core

5

@Bito_Ishmael and what that does to do with my issue?

6

U want parent node of the path search, right?


        PathNode pn = path.pathHandler.GetPathNode(node);//.cost

        if(pn.parent == null)
            return cost;

        GraphNode prev = pn.parent.node;

Hi

Thanks for the suggestion.
In the next beta version you will be able to implement ITraversalProvider.CanTraverse(path, from, to) which allows you to get the functionality you need.

@aron_granberg any news on the update? It’s been over a month since the last one and by checking the changelog this isn’t something too common :slight_smile:

I ran into some bugs right when I was about to release it. I’ll have to hold off on the update for one or two days I’m afraid.
