Boat Spawn (Roblox Studio) - roblox

Question

I'm trying(I'm very new) to make a game where you have to attack each other with a boat. There is a button on each island and when you press it, a boat should appear. (this works so far)
But as soon as you want to spawn a new boat it removes everyones boat. I thought it makes sense to use player.id but this still won't work. Does anyone know the solution?
Below you will find the code thats hidden in a part.
Thanks!
CODE:
local cd = script.Parent.ClickDetector
local boat = script.Parent.Parent.Firstboat
local button = script.Parent
local debounce = false
game.Players.PlayerAdded:Connect(function(player)
print(player.UserId)
local plruserid = player.UserId
print(player.Name)
boat.Parent = game.ServerStorage
cd.MouseHoverEnter:Connect(function()
button.Transparency = 0.5
end)
cd.MouseHoverLeave:Connect(function()
button.Transparency = 0
end)
cd.MouseClick:Connect(function()
local SetNameToBoat = plruserid
print (SetNameToBoat)
local oldboat = workspace:FindFirstChild(SetNameToBoat)
if not debounce then
if oldboat then
oldboat : destroy()
end
debounce = true
local NewBoat = boat:clone()
NewBoat.Name = (SetNameToBoat)
NewBoat.Parent = game.Workspace
wait(5)
debounce = false
end
end)
end)

Answer 1

I simplified the code and found the solution:
local cd = workspace.Button:WaitForChild('ClickDetector')
local boat = game:GetService('ServerStorage'):WaitForChild('Boat')
local button = workspace:WaitForChild('Button')
local debounce = false
cd.MouseHoverEnter:Connect(function()
button.Transparency = 0.5
end)
cd.MouseHoverLeave:Connect(function()
button.Transparency = 0
end)
cd.MouseClick:Connect(function(player)
local plruserid = player.UserId
local SetNameToBoat = plruserid
print(SetNameToBoat)
local oldboat = workspace:FindFirstChild(SetNameToBoat)
if not debounce then
if oldboat then
oldboat:destroy()
end
debounce = true
local NewBoat = boat:clone()
NewBoat.Name = SetNameToBoat
NewBoat.Parent = game.Workspace
wait(5)
debounce = false
end
end)
