From 46747f06e42cfe6ae880a2eb16dafe69918deb78 Mon Sep 17 00:00:00 2001 From: Johnny Richard Date: Thu, 15 Dec 2022 21:26:03 +0100 Subject: Create linked list data structure We will need to have a list to traverse game entities. The first idea is to implement a mutable list. In case of mutable list get too bad or error prone. We can easily change it to immutable.
