Talk:Chariot Routes

From A Tale in the Desert
Jump to navigationJump to search

I've modified the regions.jpg in an attempt to show chariot routes. Unfortunately, several of them are currently 1-way so the lines have arrows on them. If both directions are open it's like 2 arrows bumping up against eachother making a diamond shape. Um, the graphics are rudimentary & really not that good. Also, just from looking at the thumbnail, I can tell it's not always so easy to see the arrows. But for a first draft, it's better than nothing. If anyone has any suggestions or comments, feel free to leave them here or change the image. amisibastet 21:25, 23 December 2008 (EST)

Route table calculation

Here, more or less, is the code I used to generate the route table. Feel free to modify and rerun it as needed.

I cleaned this up a bit so it actually runs, tweaked the output format so it's a bit more table-like, fixed a rounding bug in computation of travel times, and added Heaven's Gate to the routes. The main page has the newly regenerated output now. --Inkoaten 07:50, 8 April 2009 (EST)

route repair nearly complete

  • Thank you for the table! That looks great!
  • Does Heavens Gate have a chariot stop now? The last time I was up there was before some of the routes were fixed by a dev call.
  • Does Cat Claw Ridge have a second route? If so, where does it go & how many points are left? Probably to Nomads' Paradise since NP has a route to CCR but if someone could confirm that'd be great.

--AmisiBastet 09:42, 6 January 2009 (EST)

CCR doesn't have its route to Nomad's Paradise up yet. I actually cheated and included it in the table; as a result a couple of the routes are unachievable at the moment (namely, optimal routes from Nomad's Paradise to Adn, Pyramid Lake, and Sinai all pass through CCR). As far as I know, Heaven's Gate doesn't have a chariot stop (or if it does, not a working one). If anyone wants to update with coordinates and routes, I can fix the table.

All Routes Repaired Now?

If all the routes are repaired, can we remove all the "open" notations? - Phae 01:28, 6 January 2010 (EST)
