How can i use coroutine.wrap with a module function

[noobingthenoobing (noobingthenoobo)]

Hi. How can i use coroutine.wrap with a module function. I have a module function and i wanted to use coroutine.wrap so that i don’t have to wait until the end of the function. i tried everything but i couldn’t find the answer.

You just have to pass the function to coroutine.wrap?

[noobingthenoobing (noobingthenoobo)]

i tried but it didin’t work it said missing argument #1

[azqjanna]

Are you doing something like this?

local myModule = require(MyModuleScipt)

local coro = coroutine.wrap(myModule.MyFunction)

i did it like this.

			-- zombie
			local zombie = enemyModule.spawn(zombieName);
			local zombieWrap = coroutine.wrap(zombie:move());
			zombieWrap();

in the module, you can return function rather than a table in task.spawn, or put your yielding part into task.spawn

[azqjanna]

move() with parentheses calls the function, so you are actually passing the result of :move() to wrap. If move returns nil then that would give you the error you see. You should pass the function itself:

	local zombie = enemyModule.spawn(zombieName);
	local zombieWrap = coroutine.wrap(zombie.move);
	zombieWrap();

Edit: Dot . not Colon :

it didin’t work i got a error it said expected (, {

[azqjanna]

Hmmm. It may not work anyway because move is a member function and wants to be called with :. You may have to do something less obvious, I will check.

i am using Egomoose’s constructor.

example:

local Vector3 = {}
Vector3.__index = Vector3

-- constructor

function Vector3.new(x, y, z)
	local self = setmetatable({}, Vector3)
	
	self.x = x or 0
	self.y = y or 0
	self.z = z or 0
	
	return self
end

Creating A Furniture Placement System

This guide was originally written for scriptinghelpers . The original can be found here . One of the most common requests I get for blog post topics are for a decoration placement system that saves. I’ve shied away from this topic in the past as there is no singular “correct” way to do it. That being said, I think it’s a good exercise for all game devs to go through and will potentially place a role in a future blog post I plan to write. In addition to change things up, I’ll also take the ti…

Why are you using this? This could cause some confusing issues because the returned self is a Table instead of a Userdata.

[noobingthenoobing (noobingthenoobo)]

it’s easier for my enemy spawn script:

local serverStorage = game:GetService("ServerStorage");
local enemies = serverStorage:WaitForChild("Enemies");

local map = game.Workspace:WaitForChild("Map");
local waypoints = map:WaitForChild("Waypoints");

local enemy = {}
enemy.__index = enemy

function enemy.spawn(enemyName)
	local self = setmetatable({}, enemy)
	
	-- enemy exist
	local enemyExist = enemies:FindFirstChild(enemyName);
	if enemyExist then
		
		-- new enemy
		self.newEnemy = enemyExist:Clone();
		self.newEnemy.HumanoidRootPart.CFrame = waypoints:FindFirstChild("1").CFrame;
		self.newEnemy.Parent = game.Workspace;
	end
	
	return self
end

function enemy:move()
	
	-- waypoints
	for i = 1, #waypoints:GetChildren() do
		if self.newEnemy:FindFirstChild("Humanoid") then
			self.newEnemy.Humanoid:MoveTo(waypoints[i].Position);
			self.newEnemy.Humanoid.MoveToFinished:Wait();
		end
	end
	
	-- destroy
	self.newEnemy:Destroy();
end

return enemy

isn’t wrap and then resume same thing as task.spawn?

task.spawn(function()
    zombie:move()
end)

Why not this one

Also what I meant was;

local Vector3 = {}
Vector3.__index = Vector3

-- constructor

function Vector3.new(x, y, z)
	local self = setmetatable({}, Vector3)
	
	self.x = x or 0
	self.y = y or 0
	self.z = z or 0
	
	return self
end

return function(desiredFunction,...)
    if Vector3[desiredFunction] then
        task.spawn(function()
            Vector3[desiredFunction](...)
        end
    end
end --something like this

[noobingthenoobing (noobingthenoobo)]

i’ll try it and see if it works.

If you want to pass in a table function that uses the colon operator to a task.spawn or coroutine.wrap, you must switch to dot operator and pass the table as the second argument.

task.spawn(zombie.move, zombie, ...)
