The Thing doesnt move???? what the hecc???

i've been Working in an optimized script ffor my sinking ship game but it just doesn't work. No error messages. No warnings. F in the chat.

--variables

local ship = script.Parent
local P = ship.PrimaryPart
local SeaLevel = 0

--scripting

local function sink()
	while true do
		local X = P.Position.X
		local Y = P.Position.Y
		local Z = P.Position.Z
		if ship.Trigger1.Position >SeaLevel then
			ship:SetPrimaryPartCFrame(
				P.CFrame * CFrame.Angles(
					math.rad(.01),0,math.rad(.01)
					)
			)
			ship:SetPrimaryPartCFrame(
				P.CFrame + Vector3.new(
					X,Y -.05,Z
					)
				)
			wait()
		end
	end
end

#You didnt call the function

You only defined a funtion as sink() But you didnt actually call it.

to do that you need to add:

sink()
