[bbgun45621]

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!
   fix bug
2. What is the issue? Include screenshots / videos if possible!
   
   

-- This is an example Lua code block
local module = {}

local debris = game:GetService("Debris")

		end
	end

	if stunDuration then
		enemyHumanoid.WalkSpeed = 16
		enemyHumanoid.JumpPower = 50
		stunHandler.Stun(enemyHumanoid,stunDuration)
	end

	if ragdoll then

			if not ragdollTrigger.Value then
				ragdollTrigger.Value = true

				task.delay(ragdollDuration,function()
					if enemyHumanoid.Health > 0 then
						ragdollTrigger.Value = false
					end
				end)
			end
		end

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.

@bbgun45621

local attackerHumRp = attacker:WaitForChild("HumanoidRootPart")

well i guess line 12 is this one
the variable “attacker” must be a boolean (true/false) so double check what it is

[bbgun45621]

[bIorbee]

whereever you call this function the attacker variable you inputted must be a boolean, go to where you called the function

[bbgun45621]

[bIorbee]

what does that equal? you can be much more helpful by giving more information other than screenshots

i want to get attacker humanoidRootPart

function module.Hit(enemyHumanoid,damage,stunDuration,knockback,attacker,ragdoll,ragdollDuration, blockBreak, player)
	
	local attackerHumRp = attacker:WaitForChild("HumanoidRootPart")
	local enemy = enemyHumanoid.Parent

	if damage then
		enemyHumanoid:TakeDamage(4)
	end

	if not blockBreak then
		if enemyBlocking then
			local direction = (attackerHumRp - enemyHumRp.Position).unit
			local enemyLook = enemyHumRp.CFrame.LookVector
			
			local dot = direction:Dot(enemyLook)
			
			if dot > -0.4  then
				print("Blocked!!")
				return
			else
				enemy:SetAttribute("Blocking",false)
			end
		end
	end

[bIorbee]

you never supplied the attacker variable to the function
you skipped over it and went straight to the ragdoll

how i can get attacker humanoidrootpart
