Problem: Advanced Path Movement - Selecting the closest node?

[GreenOnion]

Hi, I'm having a problem in figuring out a functional way the Advanced Path Movement extension would choose the node with the smallest distance to the current one, traversing to it/adding it into the 'journey' - without it selecting the current node itself or something else that's just as silly.

The attempts so far:
I first tried gathering all the nodes (through a fast-loop) and adding them into the Sort X extension, hoping it could spit out the distances sorted into shortest to longest - Which it did.. But without any documentation on the extension, I couldn't get the "GetAdress" expression to work - nor anything else - at this point the algorithm became such a mess to handle, and it seemed to select nodes at random. A while after that, it decided to stop cooperating with me completely.

Alright then, fair enough. I then decided to flip the algorithm: run a fast-loop and insert the loop index into an array, with the position dependent on the distance from the current node to the fast-loop ID node. Then I'd run a second fast-loop, which would Bubble sort (http://en.wikipedia.org/wiki/Bubble_sort) the array. This didn't come close to working when I tried it, giving similar results like the past attempt.

Okay, then I just did a fast-loop testing between all the nodes, checking which one would be the shortest (If X < Y then set Z to X; else end) but that way - It just kept selecting the current node all the time, even if I tested if the current node = the fast-loop index. Frustrated, I gave up trying.

*Sigh*

Could anyone give me some help, detailing the correct way of doing this? I've slept on the problem for two days but I can't wrap my head around it - And because Google couldn't spit out an answer, I'm trying here.

Thanks in beforehand.

I didnt use advanced pathfinding, because of a similar reason, it is very uncooperative and has issues. I suggest that if you are able to code your own pathfinding. It is much better when you can make pathfinding to meet your own needs.

Otherwise an example of your problem would be nice.

Yeah, I suppose you're right. The Advanced pathfinding extension only likes to do one thing, it seems, and becomes distressed if you'd try to mutate it into other uses. I'll code my own pathfinding and make use of that instead.

Anyway, thanks.

Maybe you can use this, or at least get ideas:
