why does this function not print anything?
i have this modulescript and localscript, and when the modulescript function is running it should print running, but it doesnt say anything, here is my code:
--localscript code:
local myModule = require(workspace.KeyHandler)
game:GetService("UserInputService").InputBegan:connect(myModule.onKeyPress())
--modulescript code:
local module = {}
function module.onKeyPress(inputObject, gameProcessedEvent)
print("running...")
if inputObject.KeyCode == Enum.KeyCode.Space then
print("Spacebar was pressed")
if(_G.wt1 == true) then
_G.wt1 = false
_G.WelcomeText2()
elseif(_G.wt3 == true) then
_G.wt3 = false
_G.WelcomeText4()
end
end
end
return module
if anyone could figure this out I would be grateful, thanks in advance!

The function in the module script has 2 parameters, inputObject and gameProcessedEvent. The function needs those 2 parameters in order to run properly. In the main script, you just have the function be called whenever the inputbegan event is fired, but you're not passing any arguments to the onKeyPress function. This can be fixed by simply getting the arguments passed to the inputBegan function, and then passing those to the onKeyPress function, like so:
--localscript code:
local myModule = require(workspace.KeyHandler)
game:GetService("UserInputService").InputBegan:connect(function(inputObject, gameProcessedEvent)
myModule.onKeyPress(inputObject, gameProcessedEvent)
end)
Or you can just connect the function directly to the event like bluetaslem's answer, like so:
--localscript code:
local myModule = require(workspace.KeyHandler)
game:GetService("UserInputService").InputBegan:connect(myModule.onKeyPress)
Both methods work properly
Hope this helped!

In this line,
game:GetService("UserInputService").InputBegan:connect(myModule.onKeyPress())
You call the function myModule.onKeyPress with no arguments (inputObject and gameProcessedEvent on line 4 of the module will both be nil).
Since you called it, it should immediately print "running...", then error, because inputObject is nil.
You are supposed to give :connect a function. onKeyPress is a function. onKeyPress() is what it returns which is nothing -- not a function.
You just need to drop the ():
game:GetService("UserInputService").InputBegan:connect(myModule.onKeyPress)
Using _G is really not a good idea for keeping your code clean or understandable.
