_G Function only runs when player respawns also doesn't run even value is set to true

Help and Feedback Scripting Support

  1. What do you want to achieve? run _G.function ONLY when a boolvalue is set to true.

  2. What is the issue? It only seems to run when player respawns and it doesn’t even run when the boolvalue is clearly set to true.
    Also when the player joins for the first time, an error saying attempt to call a nil value
    The BoolValue is set to true by a serverscript.

  3. What solutions have you tried so far? I tried adding a health function but it doesn’t seem to work too…
    Both scripts are localscripts!
    Only the server-script involved is the script that changes the boolvalue to true.

-- _G FUNCTION
_G.Ragdolled = function()
	if values:WaitForChild("Ragdolled").Value == true then
		warn("worked")
		return true
	elseif values:WaitForChild("Ragdolled").Value == false then
		return false
	end
end
-- RECEIVES _G FUNCTION
if _G.Ragdolled() then
	print("hi")
end

Despite the boolvalue being set to true (by server-script) it doesn’t seem to print “hi”.

For starters, I wouldn’t recommend using _G at all, just use normal modules.

If this is a BoolValue (though I recommend trying Attributes) then you can use the .Changed event.

Something like the following:

values.Ragdolled.Changed:Connect(function(newValue)
     if newValue then
           print("It is true!")
     else
           print("It is false!")
     end
end

I would like to also point out to not use :WaitForChild() each time, it yields your script. If you know it is there, you can use either :FindFirstChild, or just referencing it

To expand on why you shouldn’t use _G in this case (and many others) is because you are reliant on a “race condition” where you must set _G.Ragdolled = in a script before using _G.Ragdolled() in another script. but you do not specify an order explicitly so lua may do it in the correct order or not. Using a module script and require solves this, forcing Ragdolled to be set by reading the module script.

Well i just thought of using _G because it is much easier, less complex and more universal.

How would a modulescript work exactly for this scenario?
I know it uses functions just like _G, but do i just paste in the same script i used for _G.Ragdolled = function()?

6 
local module = {}

local ragdolled = values:WaitForChild("Ragdolled")

module.Ragdolled = function()
    return ragdolled.Value
end

return module

basically the same as _G but with module, then in your script you would use

local ragdoll_module = require(game.starterplayer.ModuleScript)

if ragdoll_module.Ragolled() then
    print("is ragy")
end

_G is literally a global module script, I recommend reading on them, though my solution works.

Hello sorry for the late response, i was trying to figure out modulescripts and they seem to work fine but the same issue i’m having still recurs. the module script function is only called when player respawns and not when the value is set to true.

here are the scripts.

-- MODULESCRIPT
local module = {}
local player = game.Players.LocalPlayer.Character
local value = player:FindFirstChild("Values"):FindFirstChild("Ragdolled")
function module.Ragdolled()
	if value.Value == true then
		return true
	elseif value.Value == false then
		return false
	end
end
return module
-- LOCALSCRIPT
local module = require(game.ReplicatedStorage.ModuleScript)
if module.Ragdolled() then
	print("hi") -- Only prints when player respawns, which i don't want.
end

Yeah that happens because your script is in StarterCharacterScripts. The script is run from top to bottom every time the player is created. first it gets the module, then it checks if they are ragdolled, when the script ends it does not run again.

If you want to do something when something else happens you have to use events and connections. @noahrepublic’s first response is what you are looking for.

I guess so, i was originally using remote events that fires when player is ragdolled anyways, but they seem to be unreliable, but i’ll just stick to them for now on until i find a solution.

11

Does the solution work? If so mark as solved, if not did you get any errors?

12

Partially works, like i said it only prints “hi” when the player respawns and not when the player gets ragdolled.

Please refer to my first post, use .Changed events.
