How to run a script at multiple objects but with 1 script?

[BaseplateB0T (Baseplate)]

Im using a insanely complicated stock weapon system where editing the way it works or finding hit detection in the weapon itself is likely not an option. Instead when an explosive device goes off it leaves a scorch mark that is parented to the object it most directly effected. My solution is, if an Mesh in the “Breakables” Folder has a new descendant “Explosion” then fire the server.

2 issues arise from doing this.

1. Descendant added gets fired twice because a descendant was added to the folder via Folder.Child AND a descendant was added to the Child so because of this i need to use a bool val to check if its broken.

2. I have to use a while loop because of that boolean.

local Breakables  = game.Workspace.Breakables
local Remote      = game.ReplicatedStorage.BreakObject
local Send  
local Mesh

Breakables.DescendantAdded:Connect(function(Desendant)
	if Desendant.Name == "Explosion" then
		Desendant.Parent.Broken.Value = true
	end
end)

while wait() do
	for i, v in pairs(Breakables:GetChildren()) do
		if v:IsA("MeshPart") or v:IsA("UnionOperation") then
			if v.Broken.Value == true and v.Anchored == true then
				Remote:FireServer(v)
				v.Broken.Value = false
			end
		end
	end
end

This looks very inefficient. Can you not do .ChildAdded? That should only fire once if DescendentAdded is fired twice due to a child being inserted into the explosion.

Can’t you just run the script when the descendant is added?

Breakables.DescendantAdded:Connect(function(Desendant)
	if Desendant.Name == "Explosion" then
		if (Desendant.Parent.Broken.Value == true) and (Desendant.Parent.Anchored == true) then
			Remote:FireServer(Desendant)
		end
	end
end)

If you want one script to run for multiple objects, you could try using task spawn

local folder = -- put the parts you want in a folder

for i,v in folder:GetChildren() do
    task.spawn(function()  -- basically creates a sepearate thread/script
       while true do
          print(v.Name)
          task.wait(1)
       end
    end) 
end

-- i forgot if this needs ")"

It does. If there wasn’t, the function call of task.spawn would be open. See what it looks like without the function:

task.spawn(function()

end)
task.spawn() -- Correct

task.spawn(function()

end
task.spawn( -- Incorrect

for i,v in folder:GetChildren() do
    task.spawn(function()  -- basically creates a sepearate thread/script
       while true do
          print(v.Name)
          task.wait(1)
       end
    end) 
end

This generally isn’t a good idea since you would be creating a loop for every item within the Folder, what you should Instead you is have the while loop outside the for loop which would work the exact same way:

coroutine.wrap(function() -- I get I could use task.spawn or defer but nah
    while task.wait(1) do
        local Array = folder:GetChildren() -- i prefer to do this (Idk why)
        for i,v in Array do  -- looks nicer, shorter ¯\_(ツ)_/¯
             print(v)
        end
    end

end)() -- this extra parentheses have the coroutine fire

This would basically be doing the exact same thing, if you wanted to, you can add in another coroutine or a task to prevent yielding.

I understand this, howver the op asked how to run a single script for multiple objects. I was just giving an example of how using task.spawn, you could create a new thread for each object while still only using 1 script

@TheNamesLua

inefficient. Can you not do

Nope it fires the server twice because like i said the client picks up the SAME descendant twice once in the folder and once in the child

Hey everyone, the solution i was looking for turned out to be this

local Breakables  = game.Workspace.Breakables
local Table       = Breakables:GetChildren()
local Remote      = game.ReplicatedStorage.BreakObject
local Send  

Breakables.DescendantAdded:Connect(function(Desendant)
	if Desendant.Name == "Explosion" then
		Desendant.Parent.Broken.Value = true
	end
end)

for _,Mesh in pairs(Table) do
	Mesh.ChildAdded:Connect(function(Child)
		if Child.Name == "Explosion" then
			if Mesh.Broken.Value == true and Mesh.Anchored == true then
				Remote:FireServer(Mesh)
				print("Fired")
				Mesh.Broken.Value = false
			end
		end
	end)
end
