Frage zum Modifizieren eines Mods

Auf Empfehlung habe ich mir den Mod viewtopic.php?f=11&t=7263&start=125 angeschaut. Ich finde es sehr interessant, wollte aber nicht standardmäßig "villages" auf der Karte haben. Also habe ich gefragt, ob ich das "abschalten" kann, und es kam die Antwort:

"If you want to remove the villages but leave the area flattened, so you can easily build on it, replace lines 326-342 (function generate_village) of villages.lua by "return {}"."

Das habe ich versucht, aber beim Spielstart kam dann die Meldung:
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all

Leider hat seitdem der Mod-Autor nicht mehr geantwortet. Kann mir jemand helfen, was ich falsch gemacht habe?

Damit ist gemeint, dass du diesen Abschnitt mit

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
function generate_village()
   return {}
end

ersetzen sollst. Höchstwarscheinlich hast du dabei das "end" bei Linie 323 ausversehen gelöscht.

Danke erstmal für die Antwort. Ich habe genau das gemacht, was du gesagt hast, aber nun kommt wieder eine Fehlermeldung:

Ich glaube du musst nicht die kompletten lines, sonder alles wohinter {} steht austauschen.
EDIT: Irgendwo anders musst du galube ich noch mal was entefernen/austauschen, weiß momentan leider noch nicht wo genau.

Wir können nicht sehen was Du genau gemacht hast. Aber die Fehlermeldung sagt schonmal wo etwas nicht stimmt:
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
C:\minetest-0.4.14\bin\..\mods\mg/villages.lua:325: '<name>' expected near 'function'

Es müsste wohl die vorgeschlagene Zeile
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
function generate_village()
sein. Bitte überprüfe diese noch einmal. ob Du diese korrekt abgetippt hast und dass dort keine nicht druckbaren Zeichen dzwischen kamen. Stelle zB. sicher dass zwischen "function" und "generate_village" ein Leerzeichen ist und nocht irgen eine Grütze.
Oder ist das Problem inzwischen gelöst? Die Post ist ja schon über einen Monat alt sehe ich gerade...
