Too many 'upvalues' in function, Alternatives possible?
So basically I've been trying to make a system with 61 light switches (with FilteringEnabled) that can be switched on/off across a map. The problem is that I tried many possibilities in order to make this function properly. So I tried this method, but it returns an error indicating that the function has too many upvalues. Is there any other possible alternatives to this?

that's lots of elseif statments, find a way to simplify your code saSlol2436 716 — 6y

plus, put your switches in an array since it just stores things and keeps your code organized saSlol2436 716 — 6y

I really don't know how to simplify the code, i've tried multiple methods and I can't think of another anymore Adrian12094 12 — 6y

bruh use for loops, arrays, tables, get children, and anything else! this code looks very inefficient. abnotaddable 920 — 6y

First, if you have many similar objects, it's a great idea to put them all in an array. This allows you to access a light switch based on it's number in the array, like so:
local lightSwitches = {workspace.LightSwitch1,
workspace.LightSwitch2,
workspace.LightSwitch3,
workspace.LightSwitch4,
workspace.LightSwitch5} --Continue adding your lights from here...
print(lightSwitches[1])
Alternatively, you can automate discovery of your lights, using a for-each loop. Don't do this too often, as it is quite expensive. To be more efficient, you could put all your lights into a common folder you could quickly scan through. To do this, you should name them all the same thing. It's not important for you to be able to distinguish between light switches, so this is by far the easiest solution.
local placeWithAllLights = workspace.folderWithLights --This might be workspace for you if you didn't put your lights in a folder.
local lightSwitches = {} --Telling the game that this variable will be an array, so it knows what to expect
for index, object in pairs(placeWithAllLights:GetChildren()) do --i is the index, object is the current value of the array.
if object.Name == "LightSwitch" then --check to make sure it is a light switch...
table.insert(lightSwitches, object) --add the light switch to the array
print("This is a light!")
else
print("Not a light!")
end
end
print("Finished scanning for lights, found ", #lightSwitches)
This should give you an array with all of your lights in it. Then, it's a simple matter of scanning through lights when E is pressed, and finding the closest one. This is what it would look like finished:
local placeWithAllLights = workspace.folderWithLights --This might be workspace for you if you didn't put your lights in a folder.
local lightSwitches = {} --Telling the game that this variable will be an array, so it knows what to expect
for index, object in pairs(placeWithAllLights:GetChildren()) do --i is the index, object is the current value of the array.
if object.Name == "LightSwitch" then --check to make sure it is a light switch...
table.insert(lightSwitches, object) --add the light switch to the array
print("This is a light!")
else
print("Not a light!")
end
end
print("Finished scanning for lights, found ", #lightSwitches)
local nearestLightSwitchIndex
local nearestLightDistance = math.huge
local range = 1.8 --Define your range in a variable to easily change it later...
UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.E then
for index, lightSwitch in pairs(lightSwitches) do
local distance = (chr.Torso.Position - lightSwitch.Switch.Position).magnitude
if distance <= range and distance < nearestLightDistance then --The second part guarantees that we get the absolute closest switch
nearestLightSwitchIndex = index
nearestLightDistance = distance
end
end
end
remote:FireServer(tostring(nearestLightSwitchIndex )) --Finally, convert the number index to a string for compatibility with your in place code, and fire the server.
end)
I HIGHLY recommend reading up on for loops and generic for loops, as well as tables/array. They can make life a million times easier in the long run. Hope I helped!

+1, but note: for loops aren't expensive (GetChildren is a bit, but not worth worrying about if you're not doing it regularly). If you have a folder with *just* light switches, your table of lights can come directly from :GetChildren(), rather than iterating over it and filtering by name. Finally, for the FireServer, I'd recommend sending the light switch itself, rather than its index. chess123mate 5873 — 6y

(Sending the light instead of its index isn't a concern if lights are never added/removed while the game is running.) chess123mate 5873 — 6y

@chess123mate About the check to verify a switch and the strange server firing, I wrote this code to integrate into OPs original script structure as a basically copy-paste job. Seems like a new scripter, and I didn't want to over-complicate things. Thanks for the tip about :GetChildren() though, wasn't aware it was an expensive function :) ! whenallthepigsfly 541 — 6y
