When you set a function, what happens when you put something in the brackets?
for an exampe
1 | local function hi([somthing here]) |
2 | print("What does the bracket means D: I can't find my answer on the internet.") |
3 | end |

The bracket for function() allows arguments to added in it. Example:
1 | function(arg1) |
2 | print(arg1) |
3 | end |
4 | arg1("Hello World!") |
The function would print Hello World! This use can allow developers to quickly run codes without copy and pasting it. Also this is very important for modules scripts too.
======After editing===========
A more complex situation for this would be a script requiring a module script to summon a part Exmaple:
Module Script:
1 | local module = {} |
2 | function module:SpawnPart(position, partcolor) |
3 | local part = Instance.new("Part") |
4 | part.Position = position |
5 | part.Color3 = partcolor |
6 | print("Added part!") |
7 | end |
8 | return module |
Script:
1 | local module = require(moduleScript) |
2 | module:SpawnPart(Vector3.new(0, 0, 0), Color3.fromRGB(0, 50, 100)) |
I would suggest searching up what arguments and parameters are because they play a major role in scripting. But I'll try to do my best to explain it.
01 | --// Parameters are values inside of the brackets when you create the function |
02 |
03 | local function printingfunction(x) |
04 | print(x) |
05 | end |
06 |
07 | --// Arguments are the syntax used when you call your function |
08 |
09 | printingfunction("Hello World!") |
10 |
11 | --> Console would print Hello World! |
This is a simple example of arguments and parameters. You can create more complex functions with multiple parameters and arguments
