How to check if a player pressed a key?
So, I wanna check when a player pressed a key to make a sort of "attack."
This is the current code which isn't working:
01 | game.Players.PlayerAdded:Connect(function(plr) |
02 | plr.CharacterAdded:Connect(function(char) |
03 | local UserInputService = game:GetService("UserInputService") |
04 |
05 | local key = Enum.KeyCode.R |
06 | local pressedkey = UserInputService:GetKeysPressed() |
07 |
08 | local function forceField() |
09 | for _, keypog in pairs(pressedkey) do |
10 | if (pressedkey.KeyCode == key) then |
11 | local part = Instance.new("Part",workspace) |
12 | part.Shape = Enum.PartType.Ball |
13 | part.Color3 = Color3.new(159, 243, 233) |
14 | part.Position = char.Torso.Position |
15 | part.CanCollide = true |

As DetectiveRaie said, you should use :InputBegan() to simply detect user input. Also remember UIS only works in 'LocalScript' not 'ServerScript' ( RECOMMENDED ONE )
Basic Code:
1 | local UserInputService = game:GetService("UserInputService") |
2 | local requiredKey = Enum.KeyCode.E -- key needed to run the function |
3 |
4 | UserInputService.InputBegan:Connect(function(key, gameProcessed) |
5 | if key.KeyCode == requiredKey then |
6 | -- Use remote event/function to comunicate with the server |
7 | wait(10) -- cooldown |
8 | end |
9 | end) |
Next, you will need to use remote function/event since it's client sided code if you want your attacks or stuff to be seen by all players/clients ( server )
Another way of doing it by using :GetPressedKeys() ( LESS RECOMMENDED )
Your code is actually fine and correct but there is something that makes it not work.
- You probably used ServerScript instead of LocalScript
- In line 8 of your code there's a local function named forceField and your attacks code is inside it.
- You forgot to call the function above
- If you want it to be seen by the server, you must use remote event.
Before getting into the code. There' 2 ways I usually use to detect input with :GetPressedKeys(), which are UserInputService.JumpRequest and Humanoid.Running or simply just use white loop
Basic Code: ( White Loop Usage )
01 | local UserInputService = game:GetService("UserInputService") |
02 | local requiredKey = Enum.KeyCode.R |
03 |
04 | local function getPressedKey() |
05 | local pressedKey = UserInputService:GetKeysPressed() |
06 |
07 | for _, key in pairs(pressedKey) do |
08 | if key.KeyCode == requiredKey then |
09 | print("Pressed: " , key.KeyCode) |
10 | -- Don't forget to use remote event/function |
11 | wait(10) -- cooldown |
12 | end |
13 | end |
14 | end |
15 |
16 | while wait(1) do |
17 | getPressedKey() |
18 | end |
REMINDER: ALL stuff you want to do needs to be done on the server by using remotes
FYI: You can use remote function instead of remote event to make a built in cooldown for this

Hello, from what I can see you have the code right, but instead of trying to get when a key is pressed I would check when any input from the UserInputService is detected using :InputBegan().
I believe this is what you are looking for, take a look at lines 5-8, and let me know if I am wrong. Have a great day, Raie.
