How to get an input from a table?

Help and Feedback Scripting Support

Its a pretty straight foward question.

Here is my local script code:

local InputTypes = require(script.Modules.InputTypes)

local function findColorFromInput(input)
	for _,Color in pairs(InputTypes) do
		for Index,Input in pairs(Color) do
			if Input == input.Name then
				return tostring(Color)
			end
		end
	end
	
	return nil
end

UIS.InputBegan:Connect(function(input,gp)
	if not gp then
		local color = findColorFromInput(input)
		print(color) -- prints nil everytime!!! >:(
	end
end)

My module script code, aka InputTypes:

local module = {}

module.Red = {
	Enum.KeyCode.W.Name,
	Enum.KeyCode.Z.Name,
	Enum.KeyCode.ButtonA.Name
}

module.Yellow = {
	Enum.KeyCode.A.Name,
	Enum.KeyCode.X.Name,
	Enum.KeyCode.ButtonB.Name
}

module.Green = {
	Enum.KeyCode.S.Name,
	Enum.KeyCode.N.Name,
	Enum.KeyCode.ButtonX.Name
}

module.Blue = {
	Enum.KeyCode.D.Name,
	Enum.KeyCode.M.Name,
	Enum.KeyCode.ButtonY.Name
}

return module

I figured the .Name property would be best but Im not sure if its the way to go.

Edit for clarification: I need to get the name of the color but it prints nil. My use case would be something like pressing “D” and it printing “Blue”.

Shouldn’t it be

if Input == input.KeyCode.Name then

You need to give it the KeyCode’s name, that’s probably why it’s returning nil

Its working somewhat. It no longer prints nil but now it prints:
table: 0xe38fed8...
Theres a lot more random numbers and stuff. I think this is because tables have weird names like that, is there a way I can just make it print the name of the table its in? Example:
module.Blue would print "Blue"

EDIT: Just figured out that I needed to return “_” and not “Color”. Whoops :sweat_smile:

This isn’t guaranteed, but may help you.

UserInputService:GetStringForKeyCode(input) -- This should give you a string of the player's input.

Haha it’s okay! Trial and error is what gives results! If you have anymore issues don’t be afraid to make another post!

you do not need to use the names, you can use the objects directly

local InputTypes = {}

InputTypes.Red = {
	Enum.KeyCode.W,
	Enum.KeyCode.Z,
	Enum.KeyCode.ButtonA,
}

InputTypes.Yellow = {
	Enum.KeyCode.A,
	Enum.KeyCode.X,
	Enum.KeyCode.ButtonB,
}

InputTypes.Green = {
	Enum.KeyCode.S,
	Enum.KeyCode.N,
	Enum.KeyCode.ButtonX,
}

InputTypes.Blue = {
	Enum.KeyCode.D,
	Enum.KeyCode.M,
	Enum.KeyCode.ButtonY,
}

local function findColorFromInput(inputObject)
	for color, inputs in pairs(InputTypes) do
		for _, input in pairs(inputs) do
			if input == inputObject.KeyCode then
				return tostring(color)
			end
		end
	end

	return nil
end

UIS.InputBegan:Connect(function(input,gp)
	if not gp then
		local color = findColorFromInput(input)
		print(color)
	end
end)
