I've known and looked at Widelands for about the last 10 years now and was always happy to get a quick nostalgia fix. However now with more friends staying at home and playing online games at night we are staying longer than just for 5 games. I got curious about creating my own maps then and spent some hours "painting" in the editor. It really felt like that and after i had 1 players area to my liking i could not go through with repeating the process for the others. I looked everywhere for some copy/paste capabilities but got nowhere. Well not nowhere, but to those threads that talk about map symmetry since about 2013. And boy those maps that 'gnarfk' made are REALLY hitting a nerv with me. I desperately want to play his hilbert curve map (the others too), but as soon as a geologist hammers at the >20 resource nodes the game crashes. I would love to repair it (it seems so easy) and adapt it for personal use but i cant see myself doing that 2 hours in the editor switching resource tools and sizes like a maniac. So could anyone of you that know how to create a map by script share his/her knowledge or code here? May be release an editor extension or something like that? I would already be happy with a "repeat east" feature for X players. We are regularly between 3 to 7 so it would really help us if we could extend a map to the number of players that show up to play.

Bottom line is that you can use LUA scripts to edit maps. Basically would create new empty map of expected size and using console (F6 button) you can execute your script. Top Quote

For our scripting commands, see https://www.widelands.org/documentation/index.html Busy indexing nil values Top Quote

(cant see it though because i dont know how to turn off the FPS counter) I also got a *.lua file placed in the main Widelands directory to run. (the one where the exe is in) So i tried running those lines you gave me but "f=base.map:get_field(0, 0)" is trying to INDEX a nil value (global 'base'). Trying to learn from the documentation here i changed it to ...wl.map:... but that is trying to CALL a nil value (method 'get_field'). And now i am lost again. I understand the script logic, but i got no idea how it is implemented. Pease help. Edited: 2020-12-21, 12:38 Top Quote

Best is to take a look at some scenarios which are shipped with the game. You may find them in the subfolder `campaigns` below the datadir. If you want to execute a script saved in a file from the debug console, you can do that by typing `dofile("full/path/to/script.lua")`. Not sure but i think on windows you have to use '/' as path delimiter here, not windows style '\'. Top Quote

In the editor, `wl.Editor()` needs to be used instead of `wl.Game()` Top Quote

After all i am just trying to create a "simple" copy/paste script for map editing. Yes i looked at the Island Hopping and the Atlantian water rising scripts too, but didnt find anything to help me (yet). So trying to run f=wl.Game().map:get_field(0,0) --> attempt to call a nil value (field 'Game') Sorry to bother you with error messages. just saw the last post ... thanks Edited: 2020-12-21, 13:55 Top Quote
