Problem with positioning welds

Help and Feedback Scripting Support
#1

Heyo Devforum! I have been scripting a zipline using welds, and I want to weld the player right below the part he/she is supposed to hang on, but it doesn’t work. Can someone please tell me why my script doesn’t work?

repeat wait() until game.Workspace:WaitForChild("Tower of Troubling Tutorials")
local ziplines = game.Workspace:WaitForChild("Tower of Troubling Tutorials").Ziplines:GetChildren()

local tweenservice = game:GetService("TweenService")
local runservice = game:GetService("RunService")

local player = game.Players.LocalPlayer
local playermodule = require(player:WaitForChild("PlayerScripts"):WaitForChild("PlayerModule"))
local controls = playermodule:GetControls()

for i, zipline in pairs(ziplines) do
	local isonzip = false

	local line = zipline.Line
	local finish = zipline.End
	local start = zipline.Start
	local speed = zipline.Speed
	local slider = script.Slider
	local animation = script.ZiplineHold

	start.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
			if not isonzip then
				isonzip = true
				local character = hit.Parent
				local humanoid = hit.Parent.Humanoid
				local sliderclone = slider:Clone()
				sliderclone.Parent = game.Workspace:WaitForChild("Tower of Troubling Tutorials").Ziplines
				sliderclone.PrimaryPart.Position = start.Position
				local sliderpart = sliderclone.SliderPart
				local movingsliderpart = sliderclone.Part
				local weld = Instance.new("Weld")
				weld.Part0 = character.Head
				weld.Part1 = sliderpart
				weld.Parent = sliderpart
				character.Head.CFrame = sliderpart.CFrame * CFrame.new(0,-5,0)
				local tweeninfo = TweenInfo.new(speed.Value)
				local goal = {}
				goal.CFrame = finish.CFrame
				local tween = tweenservice:Create(movingsliderpart, tweeninfo, goal)
				tween:Play()
				local loadanimation = humanoid:LoadAnimation(animation)
				loadanimation:Play()
				coroutine.wrap(function()
					while isonzip and not controls:GetActiveController():GetIsJumping() do
						runservice.Heartbeat:Wait()
					end
					weld:Destroy()
					loadanimation:Stop()
					sliderclone:Destroy()
					isonzip = false
				end)()
				wait(speed.Value)
				weld:Destroy()
				loadanimation:Stop()
				sliderclone:Destroy()
				isonzip = false
			end
		end
	end)
end

I suggest reading:

What you just could do is make C0 the offset from the head you want to use and C1 the offset from the sliderpart.
As far as I know what you meant, I thought you meant that you’re struggling with welding?

What do you mean by “doesn’t work”, does anything happen or does the weld not create at all?

#4

The weld definitely is created because the player is attached to the object, but I want it so that the player is attached below the object so that when he/she is on the zipline, it looks like they are hanging onto it.

#5

Tbh I suggest putting a rope between the part the player holds/the player itself
and the part which moves around a rope from one point to another.
This would having to weld it a lot less annoying and easier for you to script than to figure out how to use CFrames and welding.

#6

character.Head.CFrame = sliderpart.CFrame * CFrame.new(0,-5,0)

That will not get you the result you are looking for.
If this is the only thing you want to do for the weld you can use this

weld.C0 = CFrame.new(0, -5, 0)

That will position the sliderpart down 5 studs from the head

Thank you firsttobebear! This was just what I was looking for.
