Why is my flight script not functioning correctly? - roblox

Question

I'm making a flight script to use for ProtoSmasher and it's not working as intended. I want it to have a toggle button (G) and then be able to fly with a button (W). Instead of that, to get it to work I have to hold W and then press G; but if I try to let go of w to stop in the air I have to press G again.
local plr = game:GetService("Players").LocalPlayer
local char = plr.Character
local hum = char.Humanoid
local Torso = char.HumanoidRootPart
local Mouse = plr:GetMouse()
local toggle = false
local wToggle = false
Mouse.KeyDown:Connect(function(key)
if key == "w" then
wToggle = true
end
if key == "g" then
if toggle == false then
toggle = true
local BV = Instance.new("BodyVelocity",Torso)
BV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
while wToggle == true do
BV.Velocity = Mouse.Hit.lookVector*200
wait()
end
end
if toggle == true then
toggle = false
Torso:FindFirstChildOfClass("BodyVelocity"):remove()
end
end
end)
Mouse.KeyUp:Connect(function(key)
if key == "w" then
wToggle = false
end
end)

It looks like you are trying to connect to keyboard key presses, but you are doing so in the event listener for mouse button presses.
Try something like this :
local isFlying = false
local function onKeyPress(actionName, userInputState, inputObject)
local isKeyDown = userInputState == Enum.UserInputState.Begin
local isKeyUp = userInputState == Enum.UserInputState.End
if actionName == "toggleFlight" then
if isKeyUp then
isFlying = not isFlying
end
elseif actionName == "fly" then
if isKeyDown then
-- start flying forward
elseif isKeyUp then
-- stop flying
end
end
end
-- listen for keyboard input
game.ContextActionService:BindAction("toggleFlight", onKeyPress, false, Enum.KeyCode.G)
game.ContextActionService:BindAction("fly", onKeyPress, false, Enum.KeyCode.W)
