2. Add Map Files to the Game

  • In your OpenFrontIO repo, create a folder: resources/maps/<YourMapName>/

Nice, I see this is early. One suggestion would be to add an auto nation fill tool and a way to edit nations info after. That way I could select a grid density, maybe there would be some randomness, and the computer could place the bulk of the nations evenly for me across the land.

#

I like the 3 million pixel suggested land cap. lol

please add a ctrl z option to the map maker, it makes life much easyer

A Few updates have been shipped, Auto-nations and Undo/redo options

#

could you also please add a height sampler for the land tool?, It'd make removing names from maps so much easier.

Wdym by ‘removing names from maps’ and by a height sample I am assuming you want a tool a that samples a pixel and gives you the same land elevation on the land tool.

I mean like if you have a map with place names

can you do a modified version of openfront website where we can test our custom maps online without creating a lot of folders ?

pretty sure that’s doable but this means a game instance would have to be running in a dev instance, we can have an api that receives maps to test, a script that modifies all files and uploads maps received, on a dev instance hot-reload should kick it yo instantly update it.

Will probably need a better server for that my current tiny server is running more than 9 projects may god bless it’s ram.

Any way to get rid of the 3M land tile limit? @ember cloak

ember cloak
#

not atm, pretty busy with moving right now, so the project might be down for a day or 2, as I am hosting it on my server,

The reason I have the tile limit is because its recommended, I can have it more of a suggestion than an enforced limit.

Yes please
