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:
game.Players.PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(char)
local UserInputService = game:GetService("UserInputService")
local key = Enum.KeyCode.R
local pressedkey = UserInputService:GetKeysPressed()
local function forceField()
for _, keypog in pairs(pressedkey) do
if (pressedkey.KeyCode == key) then
local part = Instance.new("Part",workspace)
part.Shape = Enum.PartType.Ball
part.Color3 = Color3.new(159, 243, 233)
part.Position = char.Torso.Position
part.CanCollide = true
part.Anchored = true
wait(1)
part.Size = Vector3.new(4.623, 4.623, 4.623)
part.Transperency = 0.1
wait(1)
part.Size = Vector3.new(5.305, 5.305, 5.305)
part.Transperency = 0.2
wait(1)
part.Size = Vector3.new(6.304, 6.304, 6.304)
part.Transperency = 0.3
wait(1)
part.Size = Vector3.new(7.569, 7.569, 7.569)
part.Transperency = 0.4
wait(1)
part.Size = Vector3.new(8.88, 8.88, 8.88)
part.Transperency = 0.5
wait(1)
part.Size = Vector3.new(10.247, 10.247, 10.247)
part.Transperency = 0.6
wait(1)
part.Size = Vector3.new(11.69, 11.69, 11.69)
part.Transperency = 0.7
wait(1)
part.Size = Vector3.new(13.387, 13.387, 13.387)
part.Transperency = 0.8
wait(1)
part.Size = Vector3.new(15.039, 15.039, 15.039)
part.Transperency = 0.9
wait(1)
part:Destroy()
end
end
end
end)
end)

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:
local UserInputService = game:GetService("UserInputService")
local requiredKey = Enum.KeyCode.E -- key needed to run the function
UserInputService.InputBegan:Connect(function(key, gameProcessed)
if key.KeyCode == requiredKey then
-- Use remote event/function to comunicate with the server
wait(10) -- cooldown
end
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 )
local UserInputService = game:GetService("UserInputService")
local requiredKey = Enum.KeyCode.R
local function getPressedKey()
local pressedKey = UserInputService:GetKeysPressed()
for _, key in pairs(pressedKey) do
if key.KeyCode == requiredKey then
print("Pressed: " , key.KeyCode)
-- Don't forget to use remote event/function
wait(10) -- cooldown
end
end
end
while wait(1) do
getPressedKey()
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.
