[Yes Or No Question] Is running a function from a argument possible?

Asked by

local NPC = script.Parent.Tori


local function VanillaIcecream()
local Coordinates = script.Parent.Coordinates.VanillaIcecream.Value
NPC.Humanoid:MoveTo(CFrame.p)
NPC.Humanoid.MoveToFinished:wait()
NPC:SetPrimaryPartCFrame(CFrame)
end



function game.ReplicatedStorage.Events.SnackToServer.OnServerInvoke(Player,Type)
print(Type)
Type()
end

What I want to do is, you see that there is a function in the script. And then there is a event that is received from a client, with the argument Type. The Type name is called "VanillaIcecream, the same as the function. Is it possible to do Type()/VanillaIcecream()

Outputattempt to call local 'Type' (a string value)

Wait, I'm confused. Are you asking if you can pass a function as an argument to remotes? Perci1 4988 — 8y

In Lua, functions are variables like any other. What' special about these variables is that they can be invoked by adding parentheses on to the end.

Therefore, they can be passed as arguments to other functions and then called.

Here's an example:

local x = 5

local function fancyPrint(arg)
    print(arg)
end

local function someFunction(func, number)
    func(number)
end

someFunction(fancyPrint, x)
