How to send more then one variable in a coroutine.wrap?

#22

Hmm… Try out this code in the commandbar so we can locate the issue.

function f(a,b)
print(a,b)
end

local c = coroutine.create(f)
coroutine.resume(f,1,2)

What is in the output? If this prints the numbers 1 and 2, then your code is structured wrong.

#23

The output is this:
local c = coroutine.create(f)
coroutine.resume(f,1,2):6: invalid argument #1 to ‘resume’ (thread expected, got function)
Yes it is an error.

#24

My bad, try

function f(a,b)
print(a,b)
end

local c = coroutine.create(f)
coroutine.resume(c,1,2)
#25

The output is 1 and 2 only and not repeated.

#26

Then that’s the code working properly, meaning something is structured badly in your code. I didn’t manage to find out what, but try not using placeholder parameters and check the actual code running, with the example above implemented?

#27

Call me crazy, but do you need ANY variables for a coroutine wrap? just put it in a function and it will use those variables.

example:

function dosomething (var1, var2)
coroutine.wrap( function ()
–stuff with var1, var2 ) ()
end

#28

That could be possible but it is inefficient and would cause a mess that is hard to add anything or remove anything later on plus the variable constantly changes so you would need a new set of code for each and every possible changes, I don’t know for you but I would not want the code to be that messy and inefficient.

#29

coroutine.wrap(function)(argument1, argument2)

function Tower.Attack(newTower,plr)
	print(plr)
	local Config = newTower.Status
	local target = FindNearestTarget(newTower, Config.Range.Value)
	if target and target:FindFirstChild("Humanoid") and target.Humanoid.Health > 0 then
		local targetCFrame = CFrame.lookAt(newTower.HumanoidRootPart.Position, target.PrimaryPart.Position)
		newTower.HumanoidRootPart.BodyGyro.CFrame = targetCFrame
		if Config.Damage.Value > target.Humanoid.Health then
			plr.Money.Value += target.Humanoid.Health
		elseif Config.Damage.Value <= target.Humanoid.Health then
			plr.Money.Value += Config.Damage.Value
		end
		target.Humanoid:TakeDamage(Config.Damage.Value)
		task.wait(Config.FireRate.Value)
	end
	task.wait(0.1)
	Tower.Attack(newTower)
end

function Tower.Spawn(name, cframe, plr)
	local AllowedToSpawn = Tower.CheckSpawn(plr, name)
	if AllowedToSpawn then
		local newTower = RepStorage.Towers[name]:Clone()
		newTower:SetPrimaryPartCFrame(cframe)
		newTower.Parent = workspace.Towers
		newTower.HumanoidRootPart:SetNetworkOwner(nil)
		
		local bodyGyro = Instance.new("BodyGyro")
		bodyGyro.MaxTorque = Vector3.new(math.huge, math.huge, math.huge)
		bodyGyro.D = 0
		bodyGyro.CFrame = newTower.HumanoidRootPart.CFrame
		bodyGyro.Parent = newTower.HumanoidRootPart
		
		for i, object in ipairs(newTower:GetDescendants()) do
			if object:IsA("BasePart") then
				object.CollisionGroup = "Tower"
			end
		end
		plr.Money.Value -= newTower.Status.Cost.Value
		plr.TowerPlaced.Value += 1
		coroutine.wrap(Tower.Attack)(newTower,plr)
		else
		warn("Requested tower does not exist", name)
	end
end

Output = nil

Depends on what you are doing, I suppose, but I have not run into any problems and never once used a variable for a wrap. I use it to finish off a function that needs to both return immediately AND wait for time to pass. It happens a lot in my games… I do not use wrap for core game mechanics.

#32

No idea, should’ve worked. That’s how I always used it

#33

Weird that the things that works for others don’t work for me.

#34 
function test(A, B, C, D)
	print(A)
	print(B)
	print(C)
	print(D)
end

coroutine.wrap(test)(1, 2, 3, 4)
