local ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - tool.Handle.CFrame.p).unit * 300)

shouldn't mouse.Hit.p be nil if it clicks the sky and break the script? (Got this from wiki) I don't understand how ^ works also on that note,

how can I make this work? for reference I'm trying to create a ray to find the distance from the humanoidrootpart to at most 50 studs below the humanoidrootpart

local char = script.Parent.Parent
print(char.Name)
while wait(.1) do 
	local visualization = workspace:FindFirstChild("VisualizationOfFall") or Instance.new("Part") 
	visualization.Name = "VisualizationOfFall" 
	visualization.Parent = workspace
	local distanceToGround = Ray.new(char.HumanoidRootPart.Position, (-char.HumanoidRootPart.Position).unit*-50) 
	local part, position = workspace:FindPartOnRay(distanceToGround, char, false, true)
	local distance = (char.HumanoidRootPart.Position - position).magnitude
	visualization.BrickColor = BrickColor.new("New Yeller")
	visualization.Transparency = .5
	visualization.CanCollide = false
	visualization.Anchored = true
	visualization.Size = Vector3.new(.5,.5,distance)
	visualization.CFrame = CFrame.new(char.HumanoidRootPart.Position - position) * CFrame.new(0,0, -distance/2) 
end

That's why you use "if mouse.Target == nil then return end"

This had no relevance to the question, the way it is works no matter what, even if the mouse target is nil ( the sky ), taken straight from the wiki

Mouse.Hit.p can never be nil, as it just returns the mouse's position in the game world. Also, at line 7, that makes the ray shoot upwards, since a negative multiplied by a negative returns a positive number, so it's equivalent to Ray.new(char.HumanoidRootPart.Position, char.HumanoidRootPart.Position.unit*50)

Thanks, but that didn't work either. The part is just in a static place in the workspace.
