Elusive UserInputService bug finally tracked down

Bug Reports Studio Bugs
#1

Please fix this fast, it’s been an issue that plagues my game, and I finally got some info on it:

error text: “Invalid value for enum KeyCode”
error link: http://gyazo.com/40b19c1b1ff75eca78518cdcc5dfeade

what caused the error: mac user typing ‘!’, in chat or out of, no other character seems to trigger it

script line that faults:

function Input(InputObject,Down)
	if InputObject.UserInputType == Enum.UserInputType.Keyboard then
		if InputObject.KeyCode == Enum.KeyCode.LeftShift then -- this line here
		end
	end
end
UserInputService.InputBegan:connect(function(InputObject) Input(InputObject,true) end)
UserInputService.InputEnded:connect(function(InputObject) Input(InputObject,false) end)

Can confirm this happens. I’m on Mac and typed in “!”

#3

Can I have any information from a mod on anything about this bug? like workarounds, or a time when it’s fixed, or even a notice it’s being worked on?

#4

Ah that is what is messing me up, yea this definitely needs to be patched.

#5

Does this only happen on Macs?

#6

pretty sure it’s mac only, although it has been reported on non-macs, I suspect the people who reported it may have been not intelligent enough to know they were on a mac, as I deal with these kind of people all the time, reporting impossible bugs out of their own sheer stupidity.

#7

Fix already, or tell me it’s being worked on, or it’s in the next update.

#8

Bump, how’s it going? is this being worked on, I want to tell my users something on it.

#9

Oh, so that’s what it meant. Always wondering what that Invalid value KeyCode thing was.

There’s also another mac related keycode glitch.

If you hold shift and press X, the X input does not register until you release the shift key. This is only the case for the “X” key, everything other key works while holding shift, so I assume it is probably related to some sort of mac command with shift X.

#11

this bug is still a thing 0.0

I ran in to this bug like 3 months ago if that helps anything, I thought I posted about it here
EDIT: found it Documentation - Roblox Creator Hub

this is the date of the taking of this screen shot, 8/22/14 12:30 AM.

Also this was Mac only related bug. Could not reproduce on Windows.

Also I can confirm the lito’s bug, except It happens to me when I’m holding down Z and try to hit X, although hitting X again a second time sometimes works. it’s got to be a Mac Key Binding error.

EDIT: although I am no long able to reproduce the crash with the ’ key I strictly remember when it was broken back then I fixed the issue by removing this line of code:

keyinputs.APOSTR.Changed:connect(function()
	-- non important stuff
end)

where APOSTR is set by this code (this was not removed)

mouse.KeyDown:connect(function(key)
	-- . . . 
	if key == "'" then
		keyinputs.APOSTR.Value = true
	end
end)

mouse.KeyUp:connect(function(key)
	-- . . . 
	if key == "'" then
		keyinputs.APOSTR.Value = false
	end
end)

This line of code was also present:

IS.InputBegan:connect(function(input)
	if input.KeyCode == Enum.KeyCode.Slash then
		-- non important stuff
	elseif input.KeyCode == Enum.KeyCode.Quote then
		-- non important stuff
	elseif input.KeyCode == Enum.KeyCode.Tab then
		-- non important stuff
	end
end)
