Typchecking Problem

Help and Feedback Scripting Support
#1

So as you read by the title I have a problem with typechecking.

So here’s a basic type check script:

--!strict
local t: boolean 
t = 5

The number 5 is underlined in yellow because it’s not a boolean value, but that doesn’t show any error in the in the output. Is it not supposed to give a error or am I doing something wrong? If it’s not supposed to give a error, then what exactly can type checking be used for?

#2

It doesn’t give an error because technically it’s acceptable in lua, typechecking will only underline things in yellow to assist you in making sure you are passing the right type.

#3

Oh. I see, then here’s a follow up question:

People use type checking in remote events(for parameters), but since type checking doesn’t effect the script at all, how is type checking helpful in the remote event parameters

example:

RemoteEvent.OnServerEvent:Connect(function(Player, variable: string) 

print(variable)

--how is checking if variable is a string helpful if it doesn't stop the script?

end)
#4

It’s only there to assist you within your code

so if you do

re.OnServerEvent:Connect(function(player, var:string)
    -- anytime you use "var" in here it will be typechecked

    var() -- can't call type "string"
end)
