Implementing Bezier Curves into my barraging

[Evs0n (Evan)]

I am trying to implement Bezier Curves into my Barrage to make the flow of the arms more fluid while striking, I have looked at the following resources

Problem when doing Barrage in Arc using Bézier

Hello, I found this code for making a barrage in arc effect using Bézier curves: local function TweenArm(Arm,pivotCFrame) task.spawn(function() local ArmStartCf = Arm.CFrame local TimePassed = 0 local rnd = Random.new() local rndCF = CFrame.new(rnd:NextInteger(-4,4),rnd:NextNumber(-5,5),rnd:NextNumber(-4,4)) local Speed = 2 local Duration = (ArmStartCf.p - pivotCFrame.Position).Magnitude / Speed local tweenDelay = 0.1 TimePassed = 0 while TimePassed < Duration…

Help with bezier curves

Hello there, im trying to make parts curve with bezier curves and move to destination with random spread. The problem is, because i set the random offset on X axis, when i turn 90 degrees right which makes me match up with the X axis, parts does not spread anymore. Basically, i know the problem but not the solution. Videos of what im talking about: 1- How it should work https://gyazo.com/859cb9f0169c4a2ab85eb5540433e2ff 2-How it works when i turn right https://gyazo.com/d810b619ba6946abbc…

and still cannot figure out how it works and am completely lost in the dirt

this is the handler for the barraging the handles the tweening

local rp = game:GetService("ReplicatedStorage")
local Barrage = rp:WaitForChild("Barrage")

local TweenService = game:GetService("TweenService")

local Animations = script:WaitForChild("Animations")

local SSS = game:GetService("ServerScriptService")
local Library = SSS:WaitForChild("Library")
local DictionaryHandler = require(Library:WaitForChild("DictonaryHandler"))

local Barrage_Handler = require(script.Barrage_Handler)
local Bezier_Module = game.Workspace.Bezier

local maxDuartion = 5
Barrage.OnServerEvent:Connect(function(Player,isActive)
	local Character = Player.Character
	local Humanoid = Character.Humanoid
	local HumanoidRP = Character.HumanoidRootPart

	if not DictionaryHandler.findPlayer(Humanoid,"Stunned") and not DictionaryHandler.findPlayer(Humanoid,"Blocking") and not DictionaryHandler.findPlayer(Humanoid,"Punching") then

		if isActive then
			local Stand = Character:FindFirstChild("Stand")
			if Stand then

				local AnimControl = Stand:FindFirstChild("AnimControl")
				if AnimControl then

					local Controller = Stand.PrimaryPart:FindFirstChild("Controller")
					if Controller then
						local Folder = Instance.new("Folder",Character)
						Folder.Name = "Effects"

						Humanoid.WalkSpeed = 4
						Humanoid.JumpPower = 0 

						local goal = {}
						goal.C0 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame)
						goal.C1 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame * CFrame.new(0,.25,-2))
						local info = TweenInfo.new(.1)
						local Tween = TweenService:Create(Controller,info,goal)
						Tween:Play()

						Tween.Completed:Connect(function()
							Tween:Destroy()

							local punching = AnimControl:LoadAnimation(Animations.Barrage)
							punching:Play()
							DictionaryHandler.addTo(Humanoid,"Barraging")
							Barrage_Handler.punches(Character,Stand,Folder)
						end)

						spawn(function()
							wait(maxDuartion)

							local Folder = Character:FindFirstChild("Effects")
							if Folder then
								Humanoid.WalkSpeed = 16 
								Humanoid.JumpPower = 50 

								local goal = {}
								goal.C0 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame)
								goal.C1 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame * CFrame.new(-3,1,2))
								local info = TweenInfo.new(.1)
								local Tween = TweenService:Create(Controller,info,goal)
								Tween:Play()

								for _, track in pairs(AnimControl:GetPlayingAnimationTracks()) do
									if track.Name == "Barrage" then
										track:Stop()
										DictionaryHandler.removeFrom(Humanoid,"Barraging")
									end
								end

								Barrage_Handler.cleanUp(Folder)
							end
						end)

					end
				end
			else 
				Barrage:FireClient(Player)
			end
		else
			local Stand = Character:FindFirstChild("Stand")
			if Stand then

				local AnimControl = Stand:FindFirstChild("AnimControl")
				if AnimControl then

					local Controller = Stand.PrimaryPart:FindFirstChild("Controller")
					if Controller then
						local Folder = Character:FindFirstChild("Effects")
						if Folder then
							Humanoid.WalkSpeed = 16 
							Humanoid.JumpPower = 50 

							local goal = {}
							goal.C0 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame)
							goal.C1 = Controller.Part0.CFrame:ToObjectSpace(Controller.Part1.CFrame * CFrame.new(-3,1,2))
							local info = TweenInfo.new(.1)
							local Tween = TweenService:Create(Controller,info,goal)
							Tween:Play()

							for _, track in pairs(AnimControl:GetPlayingAnimationTracks()) do
								if track.Name == "Barrage" then
									track:Stop()
									DictionaryHandler.removeFrom(Humanoid,"Barraging")
								end
							end

							Barrage_Handler.cleanUp(Folder)
						end
					end
				end
			end
			Barrage:FireClient(Player)
		end

	else
		Barrage:FireClient(Player)
	end
end)

and this is all it does is move the arms in a straight motion instead of the wanted curve.
Can anyone help explain this in a simple way that I can understand?

not gonna explain it but i will send the proper script, here you go.

Or if you dont wanna overwrite just get the parts that will support it.
ended up like this for me
