I'm trying to make a function to be used with a brick, and if the brick is a MeshPart then the function should accept a MeshId as a parameter. Unfortunately, I couldn't figure out how to add optional parameters. Would anyone be able to help out? Here's a simplified version of the code I'm using:
local Brick={}
function Brick.new(brickType,optionalMeshIdParameter)
--do stuff
end
return Brick
Thanks for helping!
All parameters are optional in Lua. Arguments that aren't given resolve to nil.
But I suppose what you really want to do is this:
local Brick = {}
local function Brick.new(brickType, meshId)
if brickType == "MeshPart" then
print(meshId)
else
-- Otherwise ignore second parameter.
print("ignored second parameter")
end
end
return Brick
Brick.new("MeshPart", 06748472344) -- Prints the mesh ID.
Brick.new("Part", 06748472344) -- Prints "ignored second parameter"
Awesome, thanks!
So like:
if optionalMeshIdparameter ~= nil then
--do more stuff?????
end

Do you mean parameters that can have default values if no arguments are passed to them?
