Error: A module script may only connect in parallel if this instantiation of the script was required by a script associated with an actor

Pretty big eror message. Basically, i made a module that connects other modules in parallel. Pretty simple, right? Well, seems like it isn’t, because when i try to require another module (“MovementModules”) in a module that’s parented to an actor (“ParallelConnector”) it spits out this error message.

“MovementModules” has a function called “Dash” that at some point uses runservice.PreSimulation:ConnectParallel(…).
“InputReciever” asks ParallelConnector to connect the dash function in parallel.
“ParallelConnector” requires any module it’s given and runs a function that it was asked to run. In theory, because parallel connector is under an Actor, the required module SHOULD be able to :ConnectParallel, but for some reason it can’t…

Here’s the code.

-- InputReciever
local reciever = {}

local scriptapplied = false
local inputsend = game.ReplicatedStorage.clientbindableevents.sendInput
local loadedvalue = game.ReplicatedStorage.loadedmodules:WaitForChild("MovementModules"):FindFirstChild("AllMovementLoaded")
local parallelconnector = require(game.ReplicatedStorage.loadedmodules.ConnectorActor.ParallelConnector)
local movementmodulereference = game.ReplicatedStorage.loadedmodules.MovementModules
local movementmodule = require(movementmodulereference)




function reciever.GiveKey(inputname:string, timesent:number, activity:boolean)
	if os.clock() - timesent > .5 then
		warn("Error: input sent late. please report to dima!!")
	else
		if inputname == "MouseButton1" and activity == true then
			parallelconnector.RunInParallel(movementmodulereference, "Dash") -- here we're using the thingy to connect the 
		end


		if inputname == "E" then
			if activity then
				movementmodule.StartGrabCheck()
			elseif not activity then
				movementmodule.StopGrabCheck()
			end
		end
	end
end
return reciever

--ParallelConnector
local connector = {}

function connector.RunInParallel(requiredmodule, functionindex)
	require(requiredmodule)[functionindex]() -- Errors!!
end

return connector

I really gotta connect it in parallel cause i will have to use events like PreSimulation or Heartbeat a LOT in my game and i don’t want it to get laggy…

I think that there should be a way to restructure my scripts, yet i’ve looked at some posts and can’t quite find a solution that would help me. Please help.

I’m no master of parallel Luau but - to give you a start - modules cannot be required in a parallel thread unless they’re children of an Actor instance. What I suggest you to do is a bit of re-structuring on how your “parallel” module should run.

hmm, i’ll try to add on an actor to the movementmodule when im able to, thanks.

The error in your title is telling you to put the script that required said module inside an Actor instance, as Scripts/LocalScripts can only enter the Parallel execution phase by being a descendant of an Actor.

Placing Scripts within their own Actor is the only way to get parallel execution on your Script and anything within it.

By doing this you’ll then be able to connect an event to :ConnectParallel().

When you require a ModuleScript from a Script that belongs to an Actor, it will initialise the ModuleScript exclusively within that Actor. ModuleScripts that you require do not need to be a descendant of the same Actor for this to work, for example you can have them all sat outside the Actor, allowing you to better manage your ModuleScripts. This should make multi-actor setup for workload distribution much easier on your part.

#5

so, what you are saying, is that i should have a different actor for every script? and, here,

wouldn’t that make the module unable to ConnectParallel, if it’s not under an actor??

#6

and, uh, i’ve tried putting literally every script under an actor yet it still doesn’t want to connect parallel…
