Double-Tap to Run Does Not Work SPECIFICALLY with the W Key

[Vl5lX (VISIX)]

My project has four states of movement:

• Walking;
• Jogging;
• Running;
• Dashing.

After a week of struggling, I managed to implement walking and jogging, and I’m now struggling with running.
Detecting if the player has pressed a key in a specific time window, and only calling the StartRunning() from the DefaultMovement module script (which handles WalkSpeed changes) when that key is pressed under the time window works — except when “that key” is W. I have no idea why, and I don’t even know how do I even begin on trying to figure this out.

Here follows the script.

-- InputHandler
local Players = game:GetService("Players");
local UserInputService = game:GetService("UserInputService");

local player = Players.LocalPlayer;
local character = player.Character or player.CharacterAdded:Wait();
local humanoid = character:WaitForChild("Humanoid");

local DefaultMovement = require(script.DefaultMovement);
local isWalking = false;
local isJogging = false;
local currentTick = 0;
local lastTick = currentTick;
local tickWindow = 0.8;

UserInputService.InputBegan:Connect(function(input)
	if isWalking == false and input.KeyCode == Enum.KeyCode.W then
		isWalking = true;
		warn("Is " .. player.Name .. " walking?");
		DefaultMovement.StartWalking();
		--
	elseif input.KeyCode == Enum.KeyCode.LeftShift then
		isWalking = false;
		isJogging = true;
		warn("Is " .. player.Name .. " jogging?");
		DefaultMovement.StopWalking();
		DefaultMovement.StartJogging();
		--
	elseif input.KeyCode == Enum.KeyCode.F and tick() - lastTick <= tickWindow then
		-- Tried replacing the W key with any other and it worked
		-- Does not work exclusively with W and I have no idea why 
		warn("Is " .. player.Name .. " running?");
		DefaultMovement.StartRunning();
	end
end)

UserInputService.InputEnded:Connect(function(input)
	if isWalking and input.KeyCode == Enum.KeyCode.W then
		isWalking = false;
		warn(player.Name .. " will stop walking.");
		DefaultMovement.StopWalking();
		lastTick = tick();
	elseif not isWalking and input.KeyCode == Enum.KeyCode.LeftShift then
		isWalking = true;
		isJogging = false;
		warn("——" .. player.Name .. " will stop jogging.");
		DefaultMovement.StopJogging();
	elseif not isJogging and input.KeyCode == Enum.KeyCode.F then
		warn("——" .. player.Name .. " will stop running.");
		DefaultMovement.StopRunning();
	end
end)

I’m genuinely desperate at this point.

I’m sure there is a better way going about this, but I’m just gonna tell you what’s happening.

The line: if isWalking == false and input.KeyCode == Enum.KeyCode.W then is being triggerd every time because when you release “W” this line if isWalking and input.KeyCode == Enum.KeyCode.W then activates. So they go back and forth, which is why you never make it to elseif input.KeyCode == Enum.KeyCode.F and tick() - lastTick <= tickWindow then with a “W” key. So it goes, isWalking = true then isWalking = fasle reapeatedly, no matter how fast you press the keys, and only one if statement can be triggered so…

Basically I just changed some stuff around:

local Players = game:GetService("Players");
local UserInputService = game:GetService("UserInputService");

local player = Players.LocalPlayer;
local character = player.Character or player.CharacterAdded:Wait();
local humanoid = character:WaitForChild("Humanoid");

--local DefaultMovement = require(script.DefaultMovement);
local isWalking = false;
local isJogging = false;
local currentTick = 0;
local lastTick = currentTick;
local tickWindow = 0.8;

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.W and tick() - lastTick <= tickWindow then
		-- Tried replacing the W key with any other and it worked
		-- Does not work exclusively with W and I have no idea why 
		warn("Is " .. player.Name .. " running?");
		--DefaultMovement.StartRunning();
	elseif isWalking == false and input.KeyCode == Enum.KeyCode.W then
		isWalking = true;
		warn("Is " .. player.Name .. " walking?");
		--DefaultMovement.StartWalking();
		--
		lastTick = tick();
	elseif input.KeyCode == Enum.KeyCode.LeftShift then
		isWalking = false;
		isJogging = true;
		warn("Is " .. player.Name .. " jogging?");
		--DefaultMovement.StopWalking();
		--DefaultMovement.StartJogging();
		--
	end
end)

UserInputService.InputEnded:Connect(function(input)
	if isWalking and input.KeyCode == Enum.KeyCode.W then
		isWalking = false;
		warn(player.Name .. " will stop walking.");
		--DefaultMovement.StopWalking();
		--lastTick = tick();
	elseif not isWalking and input.KeyCode == Enum.KeyCode.LeftShift then
		isWalking = true;
		isJogging = false;
		warn("——" .. player.Name .. " will stop jogging.");
		--DefaultMovement.StopJogging();
	elseif not isJogging and input.KeyCode == Enum.KeyCode.W then
		warn("——" .. player.Name .. " will stop running.");
		--DefaultMovement.StopRunning();
	end
end)

So we check the time-Window first, then we check if walking/jogging. Oh! And we added lastTick = tick(); to when the player is detected walking.

Solved it, thank you!
I had figured out that the booleans were messing things up, though I had no idea on how to solve it. Never even considered changing the order.
