My god, this is horrific. I need it.

New version: 0.5

• It differentiates between constructions made from boulders, and other constructions (blocks or bars).
• You can set pathfinding costs and job delays for different creatures separately.

You still can't set costs for different castes within a race differently. Unless someone asks I'll keep it that way.

[Jiri Petru]

You, sir, are amazing.

Can this be turned on only for certain creatures/races? I was thinking having goblins not able to dig, but allowing trolls to.

Also, is there is difference between digging through rock and digging soil? (If you wanted to be extra nifty, calculate the digging speed from the density of the material - for the first time, the densities would finally see some use.)

[expwnent]

Yes, you can definitely set dig abilities for different races.

I could plausibly differentiate between soil and rock, but it'd be a pain and would slow things down a bit. Differentiating between types of rock would be a little excessive before there's a difference for normal digging.

[Jiri Petru]

Differentiating between soil and rock can be as easy as giving one an 1 in the pathing algorithm and the other one, say, a 5. I guess. Or not?

(And yes, rock types are very excessive, forget about that.)

[expwnent]

Checking whether it's soil or rock is the annoying part. Also it has to dig in several parts of the code and I'd have to make entirely sure that every place they dig or consider digging, they check for soil or rock. It's one more thing that's easy to forget and could cause hard to find bugs.

Hi

This mod is amazing.  I think it's the first time I've seen someone mod DF pathfinding. 

Quick question.  How feasible would it be to change the pathfinding for your own dwarves?  Specifically, would it be possible to change the dwarves' pathfinding so that they will path through water (assuming they can breathe water)? 

[expwnent]

Not really, no.

edit: In more detail, there's a quick check the game does to see if pathfinding is possible before it runs the algorithm. This quick check doesn't consider water to be passable. It would not be possible to intercept this before it happens and override the pathfinding. The best you could get is pathing through water/air/whatever when you already could have gotten wherever you're going on land.

This mod is amazing.  I think it's the first time I've seen someone mod DF pathfinding. 

Question: I have the impression that you rolled your own pathfinding algorithm.  Did you hook into any of DF's pathfinding code?  (Specifically the code, not the world data.)

If you did, are you willing to share some details of the hooks?  Calls in, callbacks, caveats and best practices, etc.

[expwnent]

That's not how it works. The mod runs its own pathfinding algorithm to find out what the diggers have to do to get to your dwarves, then it assigns jobs and the game does its own pathfinding thing to make the digger do the dig job. It's essentially impossible to replace DF's pathfinding code with your own.

I just have to ask: Any motivation to take on that Alpha Lightning System that was posted two months ago?

Because, you know, you already seem to have added the impossible, so why not ask for something equally hard.

[expwnent]

Haha, thanks. I like a good challenge.

Lighting or lightning? Either way I'm not sure what you're talking about.

[Meph]

I mean this abandoned project: http://www.bay12forums.com/smf/index.php?topic=125438.0

[expwnent]

I think that's a little more impossible than I'm likely to have time for.

[0x517A5D]

That's not how it works.  [...]  It's essentially impossible to replace DF's pathfinding code with your own.

Shoot, I'd hoped you had managed it.

Yeah, it looks really, really hard.  I've been exploring it for a couple of extensions I want, but....
