It is a continuation of the previous article where I’ve presented the concepts behind A* search algorithm. Last time, I’ve implemented a grid that now will be used by enemies to move around levels. That is to say, the enemies will independently wander around a game world without bumping into obstacles.

This guide makes some assumptions: You know how to configure your text editor of choice You already know the basics of Unreal Engine 5 You know how to install software on your Linux distribution of choice You are using a text editor/IDE that is capable of using LSP and DAP You have basic knowledge of and are comfortable using the Shell and a little bit of Shell-scripting Personally I use Neovim and Arch Linux, but all information in this guide should also be applicable to every other text editor/IDE with the required feature set and every other Linux distribution (and maybe even Mac or Windows, though I do not use any of those OSes).

If you want to get started as quickly as possible, this is your best bet. Coc Install coc.vim, e.g. with vim-plug inside .vimrc: Plug 'neoclide/coc.nvim' Run :CocInstall coc-clangd You will likely have to familiarize yourself with coc’s shortcuts first or customize it as you see fit. LSP Setting up LSP takes a bit of time but for those that already have it up and running, there is probably not much to do.
