Could someone help me find a good resource that explains modules I am trying to use one for my bullet hell game, but I keep getting weird errors.

There are plenty of roblox published resources on this. The main purpose of modulescripts is organisation. Other uses include object oriented programming and loading order.

Module scripts are for sharing tables, in other words, a module script is a table. Usually that table contains functions, but it can all can contain numbers, strings, etc. Module scripts are “required” so other scripts can use them like this:

-- The require function is provided a ModuleScript, then runs
    -- the code, waiting until it returns a singular value.
    local my_functions = require(script.Parent.MyFunctions)
 
    -- These are some dummy functions defined in another code sample
    my_functions.foo()
    my_functions.bar()

And the module script itself, may contain code like this:

-- Tables are store multiple values in one variable
    local my_functions = {}
    
    -- Add a few functions to the table
    function my_functions.foo()
    	print("Foo!")
    end
    
    function functions.bar()
    	print("Bar!")
    end
    
    -- ModuleScripts must return exactly one value
    return my_functions

Module scripts cannot run independently. A lot of times, people create resources in the form of module scripts for them to be required by other scripts to use that module’s functions.
