What does Event:Wait(1) do?

Help and Feedback Scripting Support
#1

When I was learning some scripting, I noticed the scripter wrote this line.

Event:Wait(1)

Now, if theres no numbers in the brackets of Wait, then I understand it is that the event will pause the script until it was fired. However, if there’s numbers inside it, what does it do?

I believe this is a very simple question to answer, and I can’t find the answer on devforum sadly.

#2

I have a hunch that it does nothing, that anything in the brackets is just ignored. It will still wait for the event to be fired, and not a moment more or less.

#3

I heard that it acts like a timeout or something?

#4

It does not do anything at all.

On WaitForChild, yes. The documentation for this says that it does nothing though.

#6

Sorry if this is off topic but, what happens if WaitForChild() has reached a timeout?

#7

It simply returns nil. I’m pretty sure.

#8

Wait() function does not have any arguments so that do nothing.

It will return nothing, and your code can error if you don’t expect that.
so to fix it, you do this

hrp = character:WaitForchild("HumanoidRootPart", 3)
if hrp then
---stuff
else
   warn("No humanoid root part!")
end

Well, it looks like I’m gonna have a hard time on how to handle NPCs that gets stuck in certain situations. Do you have an idea on how to handle this?

#12

When this is fired:

obj:WaitForChild("Object")

The script will wait for Object forever, or until it is found.

When this is fired:

obj:WaitForChild("Object",5)

The script will wait for Object for 5 seconds. If it cannot find the object in 5 seconds, it will return as nil.

In this case, let’s say I wanna use timeout for waypoints for NPC. How can I like implement a timeout for it to jump in case the NPC is stuck?

I have idea

local timeout = 10

local somesignal = something.Event
local istimeout
local fired
somesignal:Connect(function()
  fired = true
end)
local starttime = tick()
while wait(.1) do
  if fired then break end
  if tick() > timeout + starttime then
     istimeout = true
     break
  end
end

if istimeout then
   warn("Timeout!")
end

Uh, how does it set fires back to false again?

#16

That will loop forever until fired variable is true.

  if tick() > timeout + starttime then
     istimeout = true
     break
  end

It should be like this.

You can make function for this

function waitfirewithtimeout(event, timeout)
local istimeout
local fired
event:Connect(function()
  fired = true
end)
local starttime = tick()
while wait(.1) do
  if fired then break end
  if tick() > timeout + starttime then
     istimeout = true
     break
  end
end

if istimeout then
   warn("Timeout!")
end
end

That’s just wrong. Where’d you get that idea from?

I made something like that for a Zombie AI I wrote a while ago, remember it may look ugly because I optimized it, the function is for one individual zombie only (each zombie had its own script), however you can modify it.

local CustomMoveTimeout
do
	local Dummy = Instance.new("BoolValue")
	local Changed = Dummy:GetPropertyChangedSignal("Value")
	
	CustomMoveTimeout = function(Event,Time)
		Dummy.Value = false
		local Returns

		local Connection;Connection = Event:Connect(function(Reached)
			Connection:Disconnect()
			Connection = nil

			Returns = Reached
			Dummy.Value = true
		end)

		do
			coroutine.wrap(function()
				wait(Time)
				if (Returns) then return end
				if (not Connection) then return end
				Connection:Disconnect()
				Connection = nil
				Dummy.Value = true
			end)()
		end

		Changed:Wait()

		return Returns
	end
end

You use it like this:

local HasReachedGoal = CustomMoveTimeout(Humanoid.MoveToFinished,Timeout)
