Function Triggers even when if statement is false - lua

Question

local Players = game:GetService("Players")
local TouchPart = workspace["Start"]
local target = game.Workspace.Level1
local function teleport()
TouchPart.Touched:Connect(function(touched)
if touched.Parent:FindFirstChild("Humanoid") then
local Player = Players:GetPlayerFromCharacter(touched.Parent)
if Player then
--Player.Character.HumanoidRootPart.CFrame = target.CFrame + Vector3.new(0, 5, 0)
print("Teleport")
end
end
end)
end
while true do
local zeit = game.Workspace.wall1.time.Value
zeit = zeit - 1
game.Workspace.wall1.time.Value = zeit
game.Workspace.wall1.SurfaceGui.Frame.TextLabel.Text = zeit
wait(1)
print(zeit)
if zeit == 0 then
teleport()
game.Workspace.wall1.time.Value = 20
end
end
The Function Teleport should only be called if zeit == 0. And print("Teleport") should only work when zeit hits 0 and the player is touching the part.
My Problem is even if zeit isnt 0 the function teleport() prints "Teleport" into the console when a player touches the part. Am i missing something there ?

Answer 1

Your issue is that you are connecting a Touched listener every time zeit reaches zero. This listener will fire from here on out, until you disconnect it. It also means that after two loops, it will print "teleport" twice, and after three you will see it printed three times with every touch.
You either need to disconnect the listener, or simply teleport the people touching the part when the timer strikes zero. Here's how you would do the latter :
local Players = game:GetService("Players")
local TouchPart = workspace["Start"]
local target = game.Workspace.Level1
local zeit = game.Workspace.wall1.time
local wallText = game.Workspace.wall1.SurfaceGui.Frame.TextLabel
-- function for teleporting all of the players currently touching the TouchPart
local function teleport()
local touchingPlayers = {}
local parts = TouchPart:GetTouchingParts()
for _, touched in ipairs(parts) do
local Player = Players:GetPlayerFromCharacter(touched.Parent)
if Player then
touchingPlayers[Player] = touched.Parent
end
end)
-- teleport all the touching players
for player, character in pairs(touchingPlayers) do
print("Teleporting " .. player.Name)
-- character:PivotTo(target.CFrame + Vector3.new(0, 5, 0))
end
end
-- keep the wall text constantly updated
zeit.Changed:Connect(function(newValue)
wallText.Text = tostring(newValue)
end)
-- update the counter every second
while wait(1) do
zeit.Value -= 1
if zeit.Value == 0 then
teleport()
wait(1)
zeit.Value = 20
end
end
