Import town data from JSON file

[ebla71]

Just saw this new and very nice feature added to the latest nightly build

However, it seems like with the deletion of the "geodata branch" also the documentation disappered on how the *.json file coordinates are calculated

Would be nice to get that back somewhere to further play around with it ...

You don't need to look for the documentation any further than in the master branch, because it was merged in along with the rest of the change.

Ah, right, the documentation was on my PR branch that I deleted after merging into OpenTTD master. I have changed the link in the PR to point to the merged documentation in the master branch.

Thanks for the link

Just to confirm - the bottom is the coordinate system for a 2-tuple format (x y) ?!?

Just played around with it a little bit and works nicely and very intuitively once you know the orientation of the x- and y-axis.

Would be beautiful to have similar features to place signs to indicate "positions of interest" and also industries

The standard TTD coordinate system starts from the top corner, with x going down to the left and y down to the right. But you can rotate heightmaps on importation, which presumably rotates the town data too.

That's not a heightmap in the above picture but a "blank canvas" from the scenario editor ...

So it seems like in this routine, the coordinate system is rotated by 90° counter-clockwise?!?

Bug or feature?!?
