Creating a yaw value

Help and Feedback Scripting Support
#1

So, I’m working on an aircraft that uses WASD controls and it uses the steer, and throttle values to turn. I’ve already figured out the throttle system and now I need to incorporate yaw for the rudder.
I want to use the Q and E keys, how could I create a yaw value (in a local script) that changes between; 1, -1, and 0 whenever your holding Q or E. For example: when you hold Q the value is -1, when you hold E the value is 1, but when you let go of the keys, the value is 0.

How would I go about doing this?

Thanks,
– Luke

You can use the UserInputService with its InputBegan and InputEnded functions.

With these functions you can do this, for example :

local UserInputService = game:GetService("UserInputService")

local YawValue = 0

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Q then
		YawValue = -1
	elseif input.KeyCode == Enum.KeyCode.E then
		YawValue = 1
	end
end)

UserInputService.InputEnded:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Q then
		YawValue = 0
	elseif input.KeyCode == Enum.KeyCode.E then
		YawValue = 0
	end
end)

Hoping this helps you :slightly_smiling_face:

Hey, I’m getting this error…

Whenever I print the YawValue it sometimes gives me a nil value as well… I think that’s the problem but I don’t know how to fix it

#4

Is it in a localscript ? Or could you send me a screen of the script ?

#5

It’s on a server script, I have to adjust the target angle of a servo, I just changed the “char” value I have to say “no” instead of nil and its printing that message as well even though I only said to print the yaw value…

#6

UserInputService works only on the client side.

However, you can use a Remote Event to send the yaw value when the input begin or end.

#7

I’m using a server script which is where the error is coming from, and I’m already using a remote event for this, the local script is firing the event currently.

#8

So, I advise you to when you fire this event, send a variable which is the yaw value.

#9

I am doing that, but the first variable is always the character so I have to add a char variable for the yaw value to even go through

#10

Okay, I sorta figured it out but the problem is that the input is only detected once I let go…

You can do something like that :

script.Parent.Event:FireServer("EVENT1",YawValue)

-- Server Side

script.Parent.Event.OnServerEvent:Connect(function(Event1, YawValue)
	print(YawValue)
end)

If you use your events for other things, I advise you to use a Table.

#12

Okay, but what about the problem I noted above? Any solution for that?

#13

Do you fire the event when the input starts ?

#14

Here, I don’t know how to check it so here’s my local script:

local char = 0

local currentThrottle = script.Parent.Parent.Parent:GetAttribute("currentThrottle")

local UserInputService = game:GetService("UserInputService")

local event = game.ReplicatedStorage:WaitForChild("YawUpdate")

local YawValue = 0

UserInputService.InputBegan:Connect(function(input)
	event:FireServer(YawValue, char)
	if input.KeyCode == Enum.KeyCode.Q then
		YawValue = -1
	elseif input.KeyCode == Enum.KeyCode.E then
		YawValue = 1
	end
end)

UserInputService.InputEnded:Connect(function(input)
	event:FireServer(YawValue, char)
	if input.KeyCode == Enum.KeyCode.Q then
		YawValue = 0
	elseif input.KeyCode == Enum.KeyCode.E then
		YawValue = 0
	end
end)

You have to fire the event in the if otherwise it fires as soon as a player presses a key :slightly_smiling_face:

Like that :

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Q then
		YawValue = -1
		event:FireServer(YawValue, char)
	elseif input.KeyCode == Enum.KeyCode.E then
		YawValue = 1
		event:FireServer(YawValue, char)
	end
end)

Same for input ended
