Is there a way to make a function stop in the middle of running and go back to the top?

MrMatthewGamingX · December 26, 2022, 11:19pm

I have a function that’ll countdown until something explodes, but I want it to go back to the top of the function when its parent changes at any given moment. How would I make the function do that?


script.Parent.Parent.AncestryChanged:Connect(function()
	wait(4.5)
	--On
	script.Parent.TextureID = ""
	script.Parent.Material = Enum.Material.Neon
	script.Parent.Color = Color3.new(0.8, 0.164706, 0.164706)
	wait(.7)
	--Off
	script.Parent.TextureID = "rbxassetid://8196371175"
	wait(.7)
	--On
	script.Parent.TextureID = ""
	script.Parent.Material = Enum.Material.Neon
	script.Parent.Color = Color3.new(0.8, 0.164706, 0.164706)
	wait(.7)
	--Off

	Explosion.BlastRadius = 1
	Explosion.Position = script.Parent.Position

You would Call the Function Again:

function Something()
task.wait(1)
Something() -- Calls Function Again
end

Something() -- Initial Call

MrMatthewGamingX · December 26, 2022, 11:22pm

So if I reached (Example) Line 30, then the object was passed to another player, would this make it start from the begining again?

DasKairo · December 26, 2022, 11:23pm

I think this would just Call the function and continue, try adding return

return Something()

MrMatthewGamingX · December 26, 2022, 11:24pm

Would I add return to the end of the function? Never used returns before

DasKairo · December 26, 2022, 11:24pm

return just returns data and ends the function early, but in this case, it ends the function early and calls itself to repeat itself

CircDev · December 26, 2022, 11:25pm

You could use a seperate script to disable and re-enable the script

DasKairo · December 26, 2022, 11:28pm

That doesn’t seem like very good idea

MrMatthewGamingX · December 26, 2022, 11:30pm

Would this work?

DasKairo · December 26, 2022, 11:31pm

It would, but you most likely wont see it happen due to all the waits.

MrMatthewGamingX · December 26, 2022, 11:31pm

Would I put the return after every wait to get the effect I’m going for?

DasKairo · December 26, 2022, 11:32pm

return only works once in functions as it ends the function, if you would want the code to yield, try using coroutines

TortenSkjold · December 26, 2022, 11:33pm

What in the world are you trying to?

DasKairo · December 26, 2022, 11:35pm

Looks like he is trying to make a bomb

SageToxigen · December 26, 2022, 11:36pm

Do you mean yielding the function from running like what @DasKairo said?

I think task.spawn() or coroutines may help.

They basically creates a thread in the script, so the code in there will only run in that thread and loops can be placed in there without interrupting the rest of the code.

This is a simple way of creating a thread with task.spawn() and yielding it later

local thread = task.spawn(function()
print("1")
task.wait(2)
print("2")
task.wait(2)
print("3")
end)
task.wait(3)
task.cancel(thread)

I didn’t test it yet, and I’m not sure if it really cancels, but I think it does.

coroutines is the same task.spawn(), but with more features for complex scripting

MrMatthewGamingX · December 26, 2022, 11:36pm

To elaborate, this is a hot potato game. The code I put flashes the potato red and then the flashing speeds up, then it explodes and whoever is holding it blows up. When the potato gets passed to another player, I want this function to go back to the top to reset the explosion timer.

TortenSkjold · December 26, 2022, 11:36pm

I am aware. But I need more information from OP about the topic. The replies so far, have been very ineffecient. (Not gonna judge, just putting out a fact here)

MrMatthewGamingX · December 26, 2022, 11:43pm

Could I do something like this?

game.ReplicatedStorage.HotPotatoEvents.TimerReset.Event:Connect(function()--BindableEvent is from a seperate script that handles the model being swapped from player to player
	task.cancel(ExplosionFunction)
	wait()
	task.spawn(ExplosionFunction)
end)

DasKairo · December 26, 2022, 11:47pm

Just an idea

task.spawn(function()

local Time = 2

while Time >= .1 do
 -- Part 1 code
task.wait(Time/2)
-- Part 2 code
task.wait(Time/2)
Time -=.1
end


-- Explode

end)

Obviously this isnt great but, Just an idea neither less.

SageToxigen · December 26, 2022, 11:52pm

Yes, but I have a feeling that it may error because you’re canceling what’s already canceled.

I may be wrong, but just in case, maybe add a variable and a sanity check to make sure that the thread is resuming to cancel it. Run the game and then tell us if it worked.

local threadResuming = false

game.ReplicatedStorage.HotPotatoEvents.TimerReset.Event:Connect(function()--BindableEvent is from a seperate script that handles the model being swapped from player to player
	if threadResuming then
		task.cancel(ExplosionFunction); threadResuming = false
	end
	task.wait()
	task.spawn(ExplosionFunction); threadResuming = true
end)
