funny shape of cultural border?

[davidlallen]

There must be some details about how cultural borders expand. In the attached screen shot from Dune Wars, you can see a city with a large culture value, and its cultural border shape is very weird. Most importantly, this is on a map with no Y-wrap, and you can see the top edge of the map. The cultural border seems very resistant to spread to the top row, but it is not impossible; there are two squares on the top row which are part of the cultural border.

It is a little hard to tell from the screenshot which are coast terrains and ocean terrains, which is part of the reason for the weird shape. But, does anybody know what the exact rules for expanding cultural borders are? Is it harder across ocean, harder at the top edge of the map, etc?

iirc, you can gain control over every waterplot, which is in the "FC" of a land plot.
The rule fits to the picture, if i look right at it.

Solved. The mapscript was changing the *terrain* type of the plot to add the polar terrain, but I had forgotten to change the *plot* type of the plot. If you convert an ocean plot to grass, you have to set both the terrain type and the plot type. Also, it seems calling CyMap().recalculateAreas() after making all your changes is needed to lock everything in.

mmhh...okay.
The system is quite confusing.
I'll have to check, what happens with my terraforming. I guess, there's maybe also a problem like this.
