The code is meant to lower the bridge, check if it is lowered, then raise it after X time but will only lower but not raise. Have tried many methods to no resolve.
local Zone = script.Parent
local Winch = script.Parent.Parent.Model.RopePart.RopeConstraint
local Up = script.Parent.Parent.Up
local debounce = false -- bridge lifted
Zone.Touched:Connect(function(TrainInZone)
if not TrainInZone:FindFirstChild("TrainSensor") then
print("Bridge Found No Sensors")
return
end
if Up.Value == false then
print("Im Ready")
Up.Value = true
if Winch.Length <= 60 then
print("lowering")
Winch.WinchTarget = 114
wait(1)
print("Waited 4 seconds")
if Winch.WinchTarget<= 113 then
Winch.WinchTarget = 50
print("Raising")
if Winch.Length <= 60 then
Up.Value = false
print("done")
end
end
end
end
end)
It will only lower the bridge, well, now this code wont even lower it as I changed it so much that I am facing a block. It just will not work at all what-so-ever. Any help would be nice.
Mind showing the model? A video of it happening in action would be better.
It doesnt do much of “Work” now because of it being… well… a busted script due to me changing it to the point my brain isnt braining anymore. I’ve been trying for about 3 hours now, hence so many “Prints” right now testing each block.
Essentially right now due to me not knowing anything about region3 as to how complicated it is. The train enters the green area, this kicks off the “Touch” function which goes and checks to see if the bridge up is marked false as a bool value. It marks Up as true and checks to see if the Winch Length is under 60. Reason I did this is because having exact values never works. I dont know any better way. If it is under 60 then it will start to lower the bridge to a Winch target lengh of 114. it will kick off a 4 second timer (Short for testing) and after the 4 seconds, it will check to see if it is under 113 for length and then set the target to 50 to then it checks to see if it goes below 60 before marking up as false.
Essentially its to act like a draw bridge.
What I wanted to do is for it to lower then the “TrainSensor” is in the green zone and when no TrainSensors are in said zone, the bridge would lift. But again. I have 0 idea how to do that which is why im doing it like this and yet still having lots of problems.
First off, Region3, though not deprecated, has been replaced by workspace:GetPartsInPart() there’s a few other functions that do the same as the provided method like workspace:GetPartBoundsInRadius() but you should probably be using the first one since you already have a part for it.
Also, it seems you wan to rotate the bridge, you could just weld the parts and rotate the main part to rotate the bridge up. This post could help you on rotating the bridge model, Introduction to Tweening Models.
Sorry for late replay laptop died on me
Ah yes… The tween… It comes back to haunt me again… Ill try my best.
If you tag your TrainSensor parts with a CollectionService tag, you can do something like this:
-- Prefer all services at top of file to see at a glance what the script uses
local Workspace = game:GetService("Workspace")
local CollectionService = game:GetService("CollectionService")
-- Used for all GetPartsInPart queries later
local overlapParams = OverlapParams.new()
overlapParams.FilterType = Enum.RaycastFilterType.Include -- For performance, only consider a subset of parts
overlapParams.MaxParts = 1 -- Since we only care if 'at least 1' train is in the zone, stop checking after it finds 1 part to avoid unnecessary performance hits
-- References used throughout the script
local zone = script.Parent
local bridgeRopeConstraint = script.Parent.Parent.Model.RopePart.RopeConstraint
-- Configurable constants
local BRIDGE_UP_ROPE_LENGTH = 50
local BRIDGE_DOWN_ROPE_LENGTH = 114
local function checkIsTrainInZone()
-- Since trains could be created/destroyed at runtime, we update the filter to be all trains that exist at the time of this check. This sets it to a table containing all parts tagged with "TrainSensor". Only these parts will be checked.
overlapParams.FilterDescendantsInstances = CollectionService:GetTagged("TrainSensor")
-- Since we have overlapParams.MaxParts set to 1, this will return at most 1 part, but it's still in a table since GetPartsInPart can also be used to check for multiple parts, if given a different MaxParts property
local firstSensorFoundInZone = Workspace:GetPartsInPart(zone, overlapParams)
-- If there is more than 0 found parts in the zone (i.e. 1 part), then isAnySensorInZone is true. Otherwise, false (if no sensors are found in the zone)
local isAnySensorInZone = #firstSensorFoundInZone > 0
-- Returns true or false
return isAnySensorInZone
end
local function raiseBridge()
-- Set the WinchTarget to the Bridge UP value; lets the RopeConstraint handle the actual movement
bridgeRopeConstraint.WinchTarget = BRIDGE_UP_ROPE_LENGTH
end
local function lowerBridge()
-- Set the WinchTarget to the Bridge DOWN value; lets the RopeConstraint handle the actual movement
bridgeRopeConstraint.WinchTarget = BRIDGE_DOWN_ROPE_LENGTH
end
-- Used as a flag for whether or not the update should be skipped due to an ongoing update
local debounce = false
local function updateBridge()
if debounce then
-- Skip this update
return
end
-- Between here and when it gets set to false later, all updates will be skipped
debounce = true
-- Stores a boolean value (true or false)
local isTrainInZone = checkIsTrainInZone()
if isTrainInZone then
lowerBridge()
-- Allow the bridge to lower for at least 4 seconds
task.delay(4, function()
-- Since debounce was true before this point, no other updates have run since 4 seconds ago. The bridge has lowered for 4 seconds, let's allow it to update again
debounce = false
-- Call update again, which will perform another check to see if it should stay lowered or raise
updateBridge()
end)
else
-- No train is in the zone. Let's raise immediately
raiseBridge()
-- Allow any train to immediately trigger lowering the bridge again and cancel the raising
debounce = false
end
end
-- If a part touches or stops touching the zone, that's a good time to run an update to check if a train is in the zone and adjust the bridge accordingly
zone.Touched:Connect(updateBridge)
zone.TouchEnded:Connect(updateBridge)

Could you explain this bit by bit for me to learn from? I request this because I do have a slowness in learning and need things dumbed down. Forgive me. I wish to learn from these things than just use as well to grow in my understanding.
Of course! I’ve edited the code snippet with a bunch of verbose comments now.
