How do I "dymanically" make a script call it's parent script function?

Hello, I wanna change a variable from a script in a diffrent script. I’ve already seen several ways on how to do this but they all seem “static”, that means if I copy paste the object / folder the scripts are in it will probably mess up.

I have a logic script that is supposed to increase a value based on it’s current status. I wanna change that status via diffrent buttons, each of them contain their own script to change that status. All of them are in a folder. My “main” script looks like this right now:

local displayNumber = script.Parent.ActualDisplay.SurfaceGui.TEXT
local displayExplanation = script.Parent.StatusExplaination.SurfaceGui.TEXT
local rodInjection = 100
local status = "Stay"

local function action()
	
	while true do
		while status == "Inject Rods" and rodInjection<100 do
		rodInjection=rodInjection+1
		displayNumber.Text=rodInjection
		displayExplanation.Text = "Injecting Rod"
		wait(1.2)
		end
		while status == "Eject Rods" and rodInjection>0 do
		rodInjection=rodInjection-1
		displayNumber.Text=rodInjection
		displayExplanation.Text = "Ejecting Rod"
		wait(1.2)
		end
		while status == "Stay" do
		displayExplanation.Text = "Holding Position"
		wait(1.2)
	end
	end
end

function changeStatus(newStatus) -- The Buttons call this and do de thing
	status=newStatus
end

My goal is that if I duplicate the folder and give it a diffrent name (in this case a number) the scripts only work in their folders and don’t escape from it and mess everything up.

Any ideas on how I should do this? I already tought of just changing a label, however that seems inefficent.

use _G. to make global variables, they don’t need any object to work, but they are not replicated so you might consider another approach if you don’t want to make a way to replicate them.

Yeah, the problem with _G is that if I duplicate the scripts they would probably mess up as they would try to modify eachother and not their own stuff

You could make a “central” script that modifies the _G values and use remotes then (maybe a remote linked to a _G)

But then I would have to rename the _G values to diffrent names for each script which is the thing I don’t want

I tried dymanically creating the variable _G names but that didn’t work either as it just says “.LogicScript:6: attempt to call a nil value”

local displayNumber = script.Parent.ActualDisplay.SurfaceGui.TEXT
local displayExplanation = script.Parent.StatusExplaination.SurfaceGui.TEXT
local rodInjection = 100
local statusName = "rod"..script.Parent.Name

_G.getfenv()[statusName] = "Stay"
print(_G.getfenv()[statusName])

function action()
	while true do
		while _G.getfenv()[statusName] == "Inject Rods" and rodInjection<100 do
		rodInjection=rodInjection+1
		displayNumber.Text=rodInjection
		displayExplanation.Text = "Injecting Rod"
		wait(1.2)
		end
		while _G.getfenv()[statusName] == "Eject Rods" and rodInjection>0 do
		rodInjection=rodInjection-1
		displayNumber.Text=rodInjection
		displayExplanation.Text = "Ejecting Rod"
			wait(1.2)
			print("YES")
		end
		while _G.getfenv()[statusName] == "Stay" do
		displayExplanation.Text = "Holding Position"
		wait(1.2)
	end
	end
end

My first recommendation, is to just combined all the button connection into one script. So that they all can share their variables. This is probably the more ideal approach.

Second recommendation would to use NumberValue objects stored in ServerStorage and then use Instance:GetPropertyChangedSignal() to have scripts efficiently update the variables.

Thanks, I managed to solve the problem by connecting all buttons in one script, didn’t know you could do that, whoops! Thanks alot, also thanks @Cristagolem for trying to help, I appreciate it alot!

If anyone from the future finds this my code looks like this now:

local displayNumber = script.Parent.ActualDisplay.SurfaceGui.TEXT
local displayExplanation = script.Parent.StatusExplaination.SurfaceGui.TEXT
local rodInjection = 100
local status = "Stay"

local clickInject = script.Parent.Button_Inject.clickInject
local clickStay = script.Parent.Button_Stay.clickStay
local clickEject = script.Parent.Button_Eject.clickEject

local function action()
	while true do
		while status == "Inject Rod" and rodInjection<100 do
			rodInjection=rodInjection+1
			displayNumber.Text=rodInjection
			displayExplanation.Text = "Injecting Rod"
			if status == "Inject Rod" and rodInjection==100 then
					status="Stay"
				end
			wait(1.2)
		end
		while status == "Eject Rod" and rodInjection>0 do
			rodInjection=rodInjection-1
			displayNumber.Text=rodInjection
			displayExplanation.Text = "Ejecting Rod"
			if status == "Inject Rod" and rodInjection==0 then
					status="Stay"
				end
			wait(1.2)
		end
		while status == "Stay" do
			displayExplanation.Text = "Holding Position"
			wait(1.2)
		end
		wait(2)
	end
end


local function onClickInject()
	status="Inject Rod"
end

local function onClickStay()
	status="Stay"
end

local function onClickEject()
	status="Eject Rod"
end

clickInject.MouseClick:connect(onClickInject)
clickStay.MouseClick:connect(onClickStay)
clickEject.MouseClick:connect(onClickEject)

action()
