To be fair, Toady doesn't have to try and simulate 200,000+ people.

Neither does SimCity. The number of agents isn't close to the number of population, and it's not like there is any real logic being simulated anyway. Its just pathfinding at times of day for work/school/home and some random shop visits.

[Spitfire]

Maybe EA should hire Toady to rewrite their AI.

(heh)

Toady's AI is actually smarter. At least the dwarves know where their bedroom is. At least the dwarves know their job. At least the dwarves can be told that some ways are faster than others.

To be fair, Toady doesn't have to try and simulate 200,000+ people.

alway already adressed that. Basically in DF, each tile is an intersection. Of which there are a lot. A SC city will only have about 200 intersections.

And then:

Pathfinding for high-volume, low density is much easier than low-volume, high density.

A Sim City 5 person don't path find like a dwarf does. The roads themselves form the data structures that things attach to and path along, so a simple binary search will get you the ideal path very quickly. A dwarf exists in a 3d space with much more possible routes...

Have You guys read on RPS that apparently the Sims aren't actual entities unto themselves? i.e, they disappear completely from Your city upon entering a building, go to different jobs and houses every-day, etc?

[Kaje]

Any truth in this?

Hopefully, a future without EA servers isn't too far away!

Luckily in SC 4 the circular traffic was just graphical glitches.
Sims are a little dumb in their SC 4 pathfinding, but nowhere near the problems in SC 5

It wasn't a graphical glitch in SC4 though. the count of cars itself would loop, meaning you'd have 4-5K sims using the connections in your city as a loop. not good for your traffic congestion and it also siphoned off workers for jobs IIRC.

While I'm not really interested in the 'play offline' thing I would love the mod which removes the ghost citizens. One which adds back in workers you lose by deleting buildings while they're inside would be lovely too.

[Satarus]

Comparing DF's pathfinding to SimCity's pathfinding isn't fair.  DF has many more paths and much fewer actors while Sim City has far fewer paths and many more actors.  In any pathfinding algorithm, the more paths you add, you exponentially increase the complexity of the algorithm.  As you add actors to it, you increase it much more linearly.  Therefore 2000 paths with 100 actors is much much harder than 100 paths with 2000 actors.

Should be easily patchable if you just do a daily census and readd the missing ones.

Not completely lineary though, as each pather has to account for other pathers as well. (Or what they should do in an ideal situation)

[Neonivek]

this also means that by doing so he is missing out on many of the features which make SimCity a fantastic experience, such as the ability to connect and share resources with friends

Why does this somehow feel EXTREMELY sarcastic? I know it isn't, but it just seems sarcastic.

Sorry but the one thing you share with friends is misery.

This whole affair feels like a clumsily written morality tale, where someone’s unrealistic hubris gets them into trouble

No, this sounds like a tale about a mean troll that everyone keeps feeding because it will "protect the town" that then stomps on the town and no one can stop it.

EA IS NOT PAYING FOR THIS MISTAKE! Stop pretending it is. It already more then made back its money for Sim city 5.

To be fair, dwarves in DF just crouch under eachother whenever they take the same path. It'd be a total disaster if there was "traffic".

Personally I don't know why they didn't just draw paths and have the agents move along those paths instead. SURE it would have been somewhat artificial but it would have worked a lot better.
