How to get the "key" from a KeyCode?

Asked 1,070 views1 answers

So my question is this: How can I get the "key" from a KeyCode value?

Example of what I have:

game:GetService("UserInputService").InputBegan:Connect(function(input)
	workspace.Key.Value =tostring(input.KeyCode);
end);

print(workspace.Key.Value)

Currently if the key I press for example is "E" it will print "Enum.KeyCode.E". I want it to just print "E" instead.

I will also want to use this value to check for the button entered later with somthing like this:

local Key ="Enum.KeyCode."..workspace.Key.Value"

if(input.KeyCode ==Key)then
	print("Pressed key!")
end

(I assume the above code would work, haven't tested it.)

If your purpouse is to simply capture the character that has been pressed in the keyboard and you make sure it's one character only you can simply invert the string in the value and get the first letter of the string, here is an example:

game:GetService("UserInputService").InputBegan:Connect(function(input)
    workspace.Key.Value =tostring(input.KeyCode);

    local invertKey = string.reverse(workspace.Key.Value);
    local Key = string.sub(invertKey, 1, 1);
end);

print(Key);

This will make sure that Enum.KeyCode.E will be written as E.edoCyek.munE and you will simply just "cut" the string by the first character and capture that in a variable.

In the case of having more than one character you can utilize string.split() and split the string by a definet character which in this case is the character . ( dot ) and then capture whatever character you want to capture in a variable.

Here is more information on string manipulation:

If you have any more questions feel free to ask! :)

instead of reversing the string you could use -1 as the beginning of the substring

That works greatly too, capturing the last character of the string. It would only work in case your keycode is only 1 character though!
