Why won't my Rope Constraint work?!

[Auevi]

1. What do you want to achieve?
   When the Grabber touches the prize (named Handle), then they become attached via a Rope Constraint.

2. What is the issue?
   The rope is being created but the two attachments aren’t being attached to each other via a rope contraint.

3. What solutions have you tried so far?
   Watched a few videos on Youtube but everything I tried didn’t work.

local touchedConnection = nil
CLAW.Grabber.Touched:Connect(function(touch)
	if not touchedConnection then
	local prize = touch.Parent
	if prize and prize.Name == "Handle" then --Config.PrizeFolderName
			print ("claw touched toy")
			touchedConnection = touch.Parent.Touched:Connect(function() end)
			
			local rope = Instance.new("RopeConstraint")
			print ("rope created")
			rope.Length = 5
			rope.Attachment1 = prize.HandleAttachment
			rope.Attachment0 = CLAW.Grabber.Attachment
			rope.Enabled = true
			
			local prizeAttachmentPos = prize.HandleAttachment.WorldPosition
			local grabberAttachmentPos = CLAW.Grabber.Attachment.WorldPosition
			local diff = grabberAttachmentPos - prizeAttachmentPos
			prize.HandleAttachment.Position = prize.HandleAttachment.Position + diff
	
			prize.CFrame = CLAW.Grabber.CFrame  - Vector3.new(0,-1, 0)
			
		prize.Parent = CLAW.Grabber
		wait(6) -- wait for x seconds before unattaching the prize
		
			rope:Destroy()
			prize.Parent = script.Parent.PRIZEFOLDER -- set the parent back to the original prize folder
			prize.Anchored = false
			prize.CFrame = CLAW.Drop.CFrame
			touchedConnection:Disconnect()
			touchedConnection = nil
		
		end	
		end
	end)

Try and set the transparency of the rope to 0 because I think it auto sets it to 1.

[Auevi]

Transparency is not a property of a rope constraint… do you mean thickness or visibility?

[offy177 (RoScripter)]

Yeah I think it is visibility I had the same problem a bit ago.

are there any errors?

@offy177

Try and set the transparency of the rope to 0 because I think it auto sets it to 1.

that is just a visual thing, doesn’t matter visible or invisible

This may be happening because you are creating attachments via script. If you do so, then you have to set attachments’ CFrame to be blank.

prize.HandleAttachment.CFrame = CFrame.new()
CLAW.Grabber.Attachment = CFrame.new()

anyway i found the issue,
the rope is not parented to anything, so it wont affect anything. in this case i parented it to prize variable

local touchedConnection = nil
CLAW.Grabber.Touched:Connect(function(touch)
	if not touchedConnection then
	local prize = touch.Parent
	if prize and prize.Name == "Handle" then --Config.PrizeFolderName
			print ("claw touched toy")
			touchedConnection = touch.Parent.Touched:Connect(function() end)
			
			local rope = Instance.new("RopeConstraint", prize)
			print ("rope created")
			rope.Length = 5
			rope.Attachment1 = prize.HandleAttachment
			rope.Attachment0 = CLAW.Grabber.Attachment
			rope.Enabled = true
			
			local prizeAttachmentPos = prize.HandleAttachment.WorldPosition
			local grabberAttachmentPos = CLAW.Grabber.Attachment.WorldPosition
			local diff = grabberAttachmentPos - prizeAttachmentPos
			prize.HandleAttachment.Position = prize.HandleAttachment.Position + diff
	
			prize.CFrame = CLAW.Grabber.CFrame  - Vector3.new(0,-1, 0)
			
		prize.Parent = CLAW.Grabber
		wait(6) -- wait for x seconds before unattaching the prize
		
			rope:Destroy()
			prize.Parent = script.Parent.PRIZEFOLDER -- set the parent back to the original prize folder
			prize.Anchored = false
			prize.CFrame = CLAW.Drop.CFrame
			touchedConnection:Disconnect()
			touchedConnection = nil
		
		end	
		end
	end)

This may be happening because you are creating attachments via script. If you do so, then you have to set attachments’ CFrame to be blank.

attachments are positioned on the center by default.

Thank you!! This was the issue — you’re the best!
