[A16] Better Pathfinding (v1.5.2 update 2/22)

...TickMultiThread

What is that? o.O

[mathwizi2005]

A mod someone (don't know who) made that forces plant ticks into another thread, specifically every plant gets its own thread. Sadly, its kinda buggy as plants tend to.....get frozen at 5% so I don't recommend yet.

I wound't mind testing it *drools*

off topic, wth is the 'spoiler' syntax, nothing I type in seems to be accepted and I wanted to avoid a long ass post

We don't have spoiler tags here

I've spent a couple of weeks building a pathfinding algorithm tester in c#. I've finally got it to the point where both the A* and my modified weighted JPS work as optimally as I can get them. Here is a snapshot of a hand drawn rimworld like map.


As you can see, this path took 74ms. With A* the best I could get is about 300ms. That is optimal paths only, no sacrificing accuracy for performance. That is about a quarter of the time. I'm quite happy with that.

I'll post it soon, somewhere, I'm not sure where yet. Maybe I'll post a copy here for some feedback. I designed it as best I could to make it easy for anyone to add their own algorithm to test. I hope I succeeded.

So my question to you Zhentar, while doing your work, did you even pull any map data for testing purposes or do you know how I might pull data about the a map weights so I can try a real map in my program?

A bit late on this, but you can check out what I did in my github repository here (including half a dozen of my test cases): https://github.com/Zhentar/BetterPathfinding/tree/master/OfflineTester

Ok I think I found an issue. Feels more like a mod compatibility problem since....I played a game thru with no issues....then I add a few more mods and this happens.

Lets lay out the problems. Pawn randomly freezes in place and frame rate plummets significantly. Error is as follows repeating every tick or so

Something is messed up about the room Toni is in, and it's resulting in a corrupt region grid. Better Pathfinding heavily depends upon the region grid, so it tends to fail quite visibly when there are problems with it. Other parts of the game that depend upon it tend to have much more subtle effects. The region grid corruption can't be caused by Better Pathfinding, so it's most likely a result of one of the other mods (although I know there is at least one bug in the region generation algorithm in A16, so it's not impossible that it's a Vanilla issue).

Apparently the Tick Multithread mod I was experimenting with was causing the issue. The plan was to put PLANTS onto their own thread per tick but it seems it expanded beyond just plants as that one cell Toni was trying to get to was literally right next to the pawn with nothing on the tile, literally NOTHING. I have since removed the mod and the problems disappeared overnight.

I suggest you post your mod [Here] for a possible official integration.

[Zhentar]

There's no need; it's already included in A17.

FYI, that's the mods announcement thread, used to advertise the existence of a mod. I think you were meaning the mod nomination thread here: https://ludeon.com/forums/index.php?topic=29505.0

Woo hoo, that's awesome Zhentar!

[ultra4]

That is great. On one hand no need for your mod anymore, but that means you deserve a whole bunch of thanks, you made the game a lot better

That is very cool to hear (congratulations!)

I think it would be a very good idea to put a big red notice about this in the first post of this thread though. It would save a lot of time and confusion for people.

Maybe overthink your choise.
Playing on the rainforest mod, my Builder build roads through the jungle, and once he is want to break, he move straight through the jungle instead to use his own builld path.

Maybe not an issue about pathfinding, but caravan rarely exit the map through the selected direction you select at the option. I set south, because the base is at the south, south is a road closeby, and the pawns move 1 day to the north through the jungle to exit.
