I don't think I understood the meaning of returning?
Hey. I learned returning when I was a starter, and it's all fine. But lately I feel I do not know the meaning of returning and what it does so well. I use it rarely, and I use a lot of functions in my scripts. I feel maybe I got the wrong knowledge from a wrong website, or whatever. Can someone tell me what they are used for and give me an example? Thanks.

The return keyword prepares the function to give back a result. In most cases, with no procedures that provide a finished result, these functions just become what’s known as a void method.
Let’s take a look at a few examples of where we would apply return in daily code:
--// Mathematics
local function multiplyNumber(number, multiple)
return number*multiple
end
local fiveTimesFour = multiplyNumber(5,4)
print(fiveTimesFour) --// 20
--// Boolean condition
local function booleanCondition(Expression)
if (Expression) then
return true
end
return false
end
if (booleanCondition(workspace.Part:IsA("Part")) then
print("Is a Part!")
end
Note:
return will stop the function immediately, anything within the scope below will not run.
here you can understand with my script:
function rturn()
print("hi")
return 1
end
game.Workspace.scarp.Transparency = rturn()
When returned is active, it stops the function like a break in loops, return turns the function into a variable, return gave the function variable 1 to its value, therefore we change the transparency of Scrappy The Part. You can store the function in a variable like
Rat = rturn() game.Workspace.scarp.Transparency = Rat
Return is a good way to get data from a function. You won't need it too often, but every once in a while is a good thing. For example:
function returnHumanoid(part)
local humanoid = part.Parent:FindFirstChild("Humanoid")
if humanoid then
return true
else
return false
end
end
local isHumanoid = returnHumanoid(randomPart)
return is a thing which returns values such like this:
local function plus(A,B)
return A*B
end
local number = plus(1,1)
print(number)
--> the thing got printed is 2
