How can I make a parrying system that requires you to look at the opponent for it to work?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!

I’m creating a melee system and recently have thought of parrying, I don’t know how to execute this or if there is any other better methods to make it.

  1. What is the issue? Include enough details if possible!

How can I make this direction based? Is there a better way to make something like this? No tutorials have helped so far.

  1. What solutions have you thought of so far?

I’ve thought of making it so an attribute is enabled when inside the parry window and if an enemy player hits the player inside the parry state, then it causes the other user to be stunned.

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

you’d use dot product checks. here is an example usage

	local Parryer = charactergoeshere
	local Attacker = charactergoeshere

	local AttackerPosition = Parryer.PrimaryPart.Position
	loacl ParryerPosition = Parryer.PrimaryPart.Position

	local Difference = AttackerPosition - ParryerPosition

	if Diff.Magnitude == 0 then
		return
	end

	local myLookVector : Vector3 = Parryer.PrimaryPart.CFrame.LookVector
	local diffUnit = Diff.Unit

	if myLookVector.Magnitude == 0 or diffUnit.Magnitude == 0 then
		return
	end

	local dotProduct = myLookVector:Dot(diffUnit)

	dotProduct = math.clamp(dotProduct, -1, 1) -- clamp to ensure no errors

	local Angle = math.acos(dotProduct) -- returns radians, so be careful
	local Parried = Angle <= math.rad(PARRY_ANGLE_IN_DEGREES)

	-- Now do something with parried! Yaaay

	if Parried then
		print("parried")
	else
		print("not parried u suck!!")
	end
