Step-by-step Neovide/Neovim setup with Unity and Godot

• I spent a couple days trying to figure this stuff out, and I think I stumbled upon a pretty decent solution
• All other solutions I found were okay, but kinda finicky, and required you to download a unity package or something
• Anyways yeah I think this is probably the easiest setup for unity and godot yet! No more struggling with this stuff

Note!

• I have not set up DAP, so I don’t know if this setup is debugger friendly
• When I start getting into debugging I’ll come update this and fix it

Installation

• If you have the AppImage for nvim or you installed it with your system package manager, uninstall it
• Here’s a fast way to do it that sets up everything for you

curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim-linux-x86_64.tar.gz
sudo rm -rf /opt/nvim-linux-x86_64
sudo mkdir -p /opt/nvim-linux-x86_64
sudo chmod a+rX /opt/nvim-linux-x86_64
sudo tar -C /opt -xzf nvim-linux-x86_64.tar.gz

sudo ln -sf /opt/nvim-linux-x86_64/bin/nvim /usr/local/bin/

• Now go get neovide in the same way, again getting the latest release

curl -LO https://github.com/neovide/neovide/releases/download/0.15.2/neovide-linux-x86_64.tar.gz
sudo rm -rf /opt/neovide-linux-x86_64
sudo mkdir -p /opt/neovide-linux-x86_64
sudo chmod a+rX /opt/neovide-linux-x86_64
sudo tar -C /opt -xzf neovide-linux-x86_64.tar.gz

sudo ln -sf /opt/neovide /usr/local/bin/

• Now you gotta go get Unity and Godot

• (one of these is easier than the other to install...)

• if you’re on debian or its derivatives go here to download

• Everyone else good luck lmao

Aside

• By the way, if you’re just getting into Neovide you’ll realize that the .desktop file provided by default does NOT load your .bashrc (aliases, etc)

• If you care about this, I’ve included a handy little wrapper script that just runs bash in interactive mode then runs neovide

• Simply download my /desktop folder, make neovide-wrapper.sh executable, then put it anywhere

• Go into Neovide.desktop and change the Exec field to where you put it

• Then put Neovide.desktop in .local/share/applications and neovide.svg anywhere in .local/share/icons

• i just put it in the top level like a neanderthal

LSP

Unity/Godot with C#

• Go grab roslyn.nvim with this config

• Follow the guide to install the Roslyn (C#) LSP, then come back

• We’re also gonna grab roslyn-filewatch.nvim just because my god it has so many features

• You could absolutely configure the brains off these two plugins, but these are the settings that work for me

{
"seblyng/roslyn.nvim",
dependencies = {
{ "khoido2003/roslyn-filewatch.nvim", opts = {} },
},
config = function()
require("roslyn_filewatch").setup({
preset = "unity",
})

require("roslyn").setup({
lock_target = true,
filewatching = "off",
choose_target = function(targets)
if #targets == 1 then
return targets[1]
end
end,
})
end,
}

Godot with GDScript

• Make sure you don’t have the steam version it DOES NOT WORK for this guide
• Godot lsp is kinda weird because the engine is the lsp
• Meaning you don’t really have to do anything but configure it
• If you have nvim-lspconfig just run vim.lsp.enable("gdscript") literally anywhere and you’re good
• If you don’t, then put this in nvim/after/ftplugin/gdscript.lua

local port = os.getenv("GDScript_Port") or "6005"
local cmd = vim.lsp.rpc.connect("127.0.0.1", tonumber(port))

---@type vim.lsp.Config
vim.lsp.config("godot", {
name = "Godot",
cmd = cmd,
filetypes = { "gd", "gdscript", "gdscript3" },
root_markers = { "project.godot", ".git" },
})

vim.lsp.enable("godot")

Setup

• Ok now download my linker scripts (in /linker)

• Make sure everything in there is executable

• Put them somewhere easy to access bc you will have to navigate to this file a lot

• Now open /linker/code and if you’re *NOT* using neovide, open the file and follow the instructions

• Now open either a Unity or Godot project

• In Unity, go to Edit > Preferences > External Tools > External Script Editor

• Browse to where you put /linker/code

• Click Regenerate project files

• You will have to do this everytime you open Unity, to get around this make a symlink at /usr/local/bin/code that points to this path

• In Godot, go to Editor > Editor Settings > Text Editor > External

• Again, Browse to /linker/code

• Tick Use External Editor

• Happy game developing!
