I’m trying to make a WASD System but on UI. I’ve managed to script it so it moves left and right when a key is pressed, but thats it. If I press A, it goes left once, and if I press D, it goes right once. My issue is that I want the UI Image to move when A or D are being held down, and continuesly move to an according position (left or right).
This is the current A Button script:
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
script.Parent.Position = UDim2.new(0.014, 0,0.714, 0)
local debounce = false
game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
if debounce == false then
debounce = true
print("pressed A")
script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0)
end
wait(0.05)
debounce = false
end
end)
game:GetService("UserInputService").InputEnded:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
print("unpressed A")
end
end)
This is the current D Button script:
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
script.Parent.Position = UDim2.new(0.014, 0,0.714, 0)
local debounce = false
game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.D then
if debounce == false then
debounce = true
print("pressed D")
script.Parent.Position = script.Parent.Position + UDim2.new(0.01,0,0)
end
wait(0.05)
debounce = false
end
end)
game:GetService("UserInputService").InputEnded:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.D then
print("unpressed D")
end
end)
You should have a loop inside the movement, like this:
local UserInputService = game:GetService("UserInputService")
local A_pressed = false
UserInputService.InputBegan:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
if A_pressed then return end -- Abort on debounce
A_pressed = true
repeat
task.wait() -- Add in appropriate delay
script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0)
until not A_pressed
end
end)
UserInputService.InputEnded:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = false
end
end)
Note: You could replace if debounce with if A_pressed since A_pressed will be true if debounce is true.
Edit: Added task.wait(), thanks for the reminder @WoTrox!
local AHeld = false
game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
AHeld = true
end
end)
game:GetService("UserInputService").InputEnded:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
AHeld = false
end
end)
coroutine.wrap(function() --maybe using RenderStepped or Heartbeat would be better, but I will use a loop rn
while wait() do
if AHeld then
--move it left a little
end
end
end)()
i tried it but it doesn’t work…did i mess up perhaps?
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
script.Parent.Position = UDim2.new(0.014, 0,0.714, 0)
local debounce = false
local A_pressed = false
UserInputService.InputBegan:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = true
repeat
game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
if debounce == false then
debounce = true
print("pressed A")
script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0)
end
wait(0.05)
debounce = false
end
end)
game:GetService("UserInputService").InputEnded:Connect(function(inputObject, gameProcessedEvent)
if inputObject.KeyCode == Enum.KeyCode.A then
print("unpressed A")
end
end)-- Movement code
until not A_pressed
end
end)
UserInputService.InputEnded:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = false
end
end)
You put the whole InputBegan event inside the loop. Yu only have to put the script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0) part inside it. But i would recommend adding a wait() too, and also using a coroutine like I did to keep the code running outside the loop too. Or just use the Heartbeat function
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
script.Parent.Position = UDim2.new(0.014, 0,0.714, 0)
local debounce = false
local A_pressed = false
UserInputService.InputBegan:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = true
repeat
if debounce == false then
debounce = true
print("pressed A")
script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0)
end
wait(0.05)
debounce = false
until not A_pressed
end
end)
UserInputService.InputEnded:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = false
end
end)
Right now this will make the UI teleport out of the screen, because it moves to the left continuously instantly. Make sure you add a wait(0.1) to slow it down
@WoTrox@domboss37@ifkpop (sorry for tagging btw), Your Scripts are probably be working, but i think the issue is that the UserInputService is underlined, as seen in the photo. Why?
Your UserInputService doesn’t exist. Add this to the beginning of the script
local UserInputService = game:GetService("UserInputService")
You first have to get the service from Roblox to be able to use it. That’s what that line does, it tells the script that it needs to use the User Input Service, which you store in a variable called “UserInputService”
Also, make sure its in a LocalScript, not a “normal” script
Since you don’t need to know when the keys are released, you can boil this down to a few checks in a RenderStepped loop:
RunService.RenderStepped:Connect(function()
if UserInputService:IsKeyDown(Enum.KeyCode.W) then
print"W down"
end
if UserInputService:IsKeyDown(Enum.KeyCode.A) then
print"A down"
end
if UserInputService:IsKeyDown(Enum.KeyCode.S) then
print"S down"
end
if UserInputService:IsKeyDown(Enum.KeyCode.D) then
print"D down"
end
end)
local UserInputService = game:GetService("UserInputService")
local A_pressed = false
UserInputService.InputBegan:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
if A_pressed then return end -- Abort on debounce
A_pressed = true
A_pressed = false
repeat
script.Parent.Position = script.Parent.Position - UDim2.new(0.01,0,0)
until not A_pressed
A_pressed = true
end
end)
UserInputService.InputEnded:Connect(function(inp, processed)
if inp.KeyCode == Enum.KeyCode.A then
A_pressed = false
end
end)
