Grappling hook rope CFrame messed up, possibly of raycastresult

[lamcellari (LamSouls)]

So i wanted to make a grappling hook, the ones where they have a rope that lets you climb, it creates a “rope”. I want to make it so that for every raycast hit, it creates a rope, with the appropiate size and position. The problem is, Its not quite working as i expected it to.

local function visualray(origin,respos)
	local dist = (origin - respos).Magnitude
	local part = Instance.new("Part")
	part.Anchored = true
	part.CanCollide = false
	part.Parent = workspace
	part.Size = Vector3.new(0.1,0.1,dist)
	part.CFrame = CFrame.new(origin,respos)*CFrame.new(0,0,-(dist/2))
	part.Material = Enum.Material.Plastic
	
	
	debirs:AddItem(part,1)
	
end

cast.LengthChanged:Connect(function(activecast,lastpointray,raydir,displacement,segmentvelocity,cosmeticbulletobject)
	local lenght = cosmeticbulletobject.Size.X/2
	local offset = CFrame.new(0,0,-(displacement - lenght))
	local directionray =  cosmeticbulletobject.Position + Vector3.new(0,-30,0)
	cosmeticbulletobject.CFrame = CFrame.lookAt(lastpointray,lastpointray+raydir):ToWorldSpace(offset)
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Exclude
	params.FilterDescendantsInstances = {Character,Character.Grapplinghook.Handle,cosmeticbulletobject}
	local raycastresult = workspace:Raycast(cosmeticbulletobject.Position,directionray,params)
	visualray(cosmeticbulletobject.Position,directionray)
	if raycastresult then
		print(raycastresult.Position)
		lastYpos = raycastresult.Position.Y
		local ropepart = game.ReplicatedStorage.rope:Clone()
		local initialposition = ropepart.endofrope.Position
		local initialsize = ropepart.Size
		local dist = (lastpoint - raycastresult.Position).Magnitude
		local dir = (lastpoint - raycastresult.Position).Unit
		
		ropepart.Size = Vector3.new(0.1,0.1,dist)
		ropepart.CFrame = CFrame.new(lastpoint,raycastresult.Position) * CFrame.new(0,0, -dist/2)
		

		local newSize = ropepart.Size
		local scaleFactorFromOriginal = (newSize)/initialsize
		ropepart.endofrope.Position = initialposition*scaleFactorFromOriginal
		ropepart.Name = "rope"
		ropepart.Parent = game.Workspace.Rope
		lastpoint = raycastresult.Position
	end
end)

cast.RayHit:Connect(function(cast,raycastresult,segmentvelocity,cosmeticbulletobject)
	cosmeticbulletobject:Destroy()
	lastYpos = 0
	lastpoint = nil
end)

RE.OnServerEvent:Connect(function(player,state,mousepos,handle,lastXposRE,lastYposRE,lastZposRE)
	Character = player.Character
	local origin =  handle.Shoot.FirePoint.Position
	lastpoint = player.Character.HumanoidRootPart.Position
	local dir = (mousepos - origin).Unit
	cast:Fire(handle.Shoot.FirePoint.WorldPosition,dir,100,behavior)
end)

NOTE: Im using fastcast for the grapplehook, but im using raycastresults for my rope. I believe there is a problem with the raycastresult since everytime it prints the raycastresult.Position, it brings me to the rope, also im using an attachment for the rope which moves everytime the rope gets sized

i also didnt copy the variables on the first lines since i dont think they are important atm

with the help of a really cool dude, he fixed the code by replacing

local raycastresult = workspace:Raycast(cosmeticbulletobject.Position,directionray,params)

to:

local raycastresult = workspace:Raycast(cosmeticbulletobject.Position,Vector3.new(0,-30,0),params)
