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

Help and Feedback Scripting Support
#1

The way to send a single variable through a coroutine function is through the following code–

coroutine.wrap(function.move)(EndCFrame)

But I wish to send more than one variable though it so how do I do it?

#2 
coroutine.wrap(function.move)(EndCframe,AnotherVariable)

?

#3

Tried but it return with a nil.

#4

How about

local c = coroutine.create(function.move)
coroutine.resume(c,EndCframe,AnotherVariable)

?

#5

Still a nil and not the intended variable value.

#6

Then there is something wrong with your function, not coroutine.wrap. Send the code you call the function from and the function itself. (function.move)

Also, task.spawn does the same thing:

task.spawn(function.move, EndCframe, AnotherVariable)

I believe another way is to send a dictionary, but I suggest to do what @majdTRM said.

coroutine.wrap(function.move)({EndCFrame = EndCFrame, SomethingElse = 2})

Here is the function being coroutined:

function 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

And here is the code from the function that is it called from:

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

What about the place where you create it? (Coroutine wrap it)

#11

It is included with the other one just now.

#12

Does making the variables a dictionary work…?

#13

The second (or the wanted variable) comes from another script. Plus, the two variable would constantly be changed so making it a dictionary would not be viable.

#14

What does that mean, usage of BindableEvents?

#15

No it is the usage of BindableFunction between a server script and a local script. However, the code is working perfectly and the variable is the intended value but just unable to send to the other function.

#16

For clarification, is the Tower.Spawn function the function.move function?

#17

No, the Attack function is the function.move function and the Tower.Spawn function is just the part where the coroutine code is located in.

#18

Then I believe you’re giving the wrong parameters to function.move, as it would appear to need a Tower model and a player, not a CFrame

#19

The CFrame is just for placeholder for the actual variable and it is not used in the actual code.

#20

So the newTower variable isn’t nil? Trying out the create-resume method, passing… let’s say, a number as a parameter as the plr variable would still be nil?

#21

Yes the newTower variable isn’t nil but the plr variable is nil to the other function even if it is a number.
