Installing Fusion

Install via Roblox

If you are creating Luau experiences in Roblox Studio, then you can import a Roblox model file containing Fusion.

• Head over to Fusion's 'Releases' page.
• Click the 'Assets' dropdown to view the downloadable files:

• Click on the Fusion.rbxm file to download it. This model contains Fusion.

• Head into Roblox Studio to import the model; if you're just following the tutorials, an empty baseplate will do.
• Right-click on ReplicatedStorage, and select 'Insert from File':

• Select the Fusion.rbxm file you just downloaded. Y
• You should see a 'Fusion' module script appear in ReplicatedStorage!

Now, you can create a script for testing:

• Create a LocalScript in StarterGui or StarterPlayerScripts.
• Remove the default code, and paste the following code in:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Fusion = require(ReplicatedStorage.Fusion)

• Press 'Play' - if there are no errors, everything was set up correctly!

Install as Source Code

If you're using pure Luau, or if you're synchronising external files into Roblox Studio, then you can use Fusion's source code directly.

• Head over to Fusion's 'Releases' page.
• Under 'Assets', download Source code (zip). Inside is a copy of the Fusion GitHub repository.
• Inside the zip, copy the src folder - it may be inside another folder.
• Paste the src folder into your local project, wherever you keep your libraries
  • For example, you might paste it inside a lib or shared folder.
• Rename the pasted folder from src to Fusion.

Once everything is set up, you should be able to require() Fusion in one of the following ways:

-- Rojo
local Fusion = require(ReplicatedStorage.Fusion)

-- darklua
local Fusion = require("../shared/Fusion")

-- vanilla Luau
local Fusion = require("../shared/Fusion/init.luau")
