Ich habe mit Python eine Hex-Map erstellt

Ich mache ein Spiel mit der Python-Bibliothek "Pygame" als Teil meines Studiums in der Schule. Da es sich um ein Simulationsspiel handelt, habe ich versucht, eine gemeinsame Hex-Karte zu erstellen, aber der Code, der verwendet werden kann, ist nicht leicht zu treffen. Immerhin habe ich beschlossen, es von Grund auf neu zu machen. Es war ... aber ich bat den Qiita-Benutzer shiracamus, den kindischen Code neu zu schreiben! Vielen Dank.
