"Int'l Date Line"??

[Jawn Henry]

I just read this from the GOTM forum:

Did anyone notice that the Buffalo you start on,next to that string of lakes, is next to the "international date line" and can be used by two cities? I bet DoM had to work to set that up!

Whazzat?? Never noticed that a square could be used 2x before... Does this work in ToT?

The IDL is the "seam" of the map - where horizontal coordinate 0 meets the highest horizontal coordinate. Some of the algorithms of the game do not adjust for this correctly in round/wrapped maps. The notable ones are the GoTo command and the city duplicate tile working checker. Two cities can share the same tile if they are located on opposite sides of the IDL.

Ok, but is it just one row of squares that is affected, or the squares on oth sides of this?

The "seam" is between vertical columns of tiles (eg, between (98,0) and (0,0), and between (99,1) and (1,1) on a 50x80 map). If one city is located so that one or more of its city radius tiles are on the other side of the "seam", it can share those tiles with a city on the other side, and vice versa. Both sides of the "seam" are affected.

The way it works is that cities on opposite sides of the IDL can use the same square if it is in each of their city radii. Because of the IDL, the game engine does not recognize that a city on the other side of the line has a square being worked by a city on the opposite side of the line. Basically, you have two cities, one on each side of the IDL. Any squares that are covered by both cities, ie overlapping city radius, can be worked by both cities.

This usually does not occur because the map generator tries to put the IDL in the seas. However, evil, insidious, Gotm Mods sometimes generate maps to make the game more interesting.

The one exception (in my experience) is the tile each city is actually located on: THAT tile is only worked by the occupying city, and it will show up in the other city's screen as occupied by a city, althoug all of the surrounding tiles will be available to be worked (even if they are being worked by the other city - or any other city - on the other side of the dateline).

Ooo, hey! I'm a "Warlord" now.

Hey, "Warlord" - time for some Early Conquest games?

 

[Jawn Henry]

Wow! That's pretty neat... in some ways. :devil Good to know, at least. Thanks everyone!

*Sigh* I am just sorely lacking in that conquest mindset. Instead of going HBR-Mys-Poly, I'm always heading for early Republic, banking, trade . . . . I just don't have TIME for a war.
