Can I use return to call a set of numbers?
Is it possible to use return to call a set of numbers? I'm sorry if this doesn't make much sense, I'm still kind of new to this and I'm not really sure how to word it right. Here is a section of my script so you can get a better idea of what I'm asking.
if game:GetService("MarketplaceService"):PlayerOwnsAsset(plr,passId) then
Val = DataStore:GetAsync("Pos")
if Pos then
return Pos
else
return -151.4, 36.5, -138
end
plr.CharacterAdded:connect(function(Character)
Hum = Character:FindFirstChild("HumanoidRootPart")
HumPos = Hum.Position
local Humanoid = Character:FindFirstChild("Humanoid") -- find the humanoid, and detect when it dies
if Humanoid then
Humanoid.Died:connect(function()
wait(respawnTime) -- delay, then respawn the character
plr:LoadCharacter()
end)
end
end)
plr:LoadCharacter()
local HumPos = Val
On line 6 I am returning a set of numbers, is this possible or do I need to use a different approach? Thanks!

Returning the numbers as a table would be one approach. Change line 6 to:
return {-151.4, 36.5, -138}
Then you can call each number with its corresponding table index, such as:
local myTable = {-151.4, 36.5, -138}
local number1 = myTable[1]
local number2 = myTable[2]
local number3 = myTable[3]

JetCrusherTorpedo is correct, usually you would want to return a list (table) of values.
In this case, it would be better to return a Vector3 since this encapsulate 3 numbers into one value, and is actually the way we represent positions:
return Vector3.new(-151.4, 36.5, -138);
However, you can do exactly what you did. You can return multiple values from a function. Those will be treated as consecutive arguments to a function it is applied to, or as several variables in an assignment:
function numbers()
return 1, 2, 3;
end
local A,B,C = numbers();
local vec = Vector3.new( numbers() );
print(A); -- 1
print(B); -- 2
print(C); -- 3
print(vec); -- 1, 2, 3
