Attempted To Index Nil with "Connect"

Help and Feedback Scripting Support
#1

Hi all,

I am attempting to Connect a function whenever the Value of a StringValue changes.

Here is the section of the script that the error is coming from:

Summary 
State.Value.Changed:Connect(function(old, new)
		if StateTracker.State == "onRunning" then
			print("Running check Good")
			canDoubleJump = false
			hasDoubleJumped = false
			humanoid.JumpPower = oldPower
			humanoid.PlatformStand = true
		elseif StateTracker.State == "onFreeFall" then
			print("Freefall Check Good")
			wait(.1)
			canDoubleJump = true
		end
	end)

A little bit of background as to why I’m not just using HumanoidStateType:

Summary

I am using Gravity Controller which makes using HumanoidStateType basically impossible. The work around was included in Gravity Controller and basically makes a new HumanoidState tracking system, which is working fine.

I have a StringValue that is allowing me to keep track of the current humanoid state of the player, which seems to be working fine.
I am trying to detect when this value changes, and to connect a function when that happens, allowing me to execute a double jump script.

This is the entire double jump script I currently have, it is kind of messy haha:

Summary 
module = require(game:GetService("StarterPlayer").StarterCharacterScripts:WaitForChild("ModuleScript"))

local PLAYERS = module.PLAYERS
local GravityController = module.GravityController
local Controller = module.Controller
local StateTracker = module.StateTracker


local player = game.Players.LocalPlayer
local UIS = game:GetService("UserInputService")
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")

local State = character:WaitForChild("State")

local Animation = Instance.new("Animation")
Animation.AnimationId="rbxassetid://5930179191"

local FlapAN = humanoid:LoadAnimation(Animation)

local canDoubleJump = false
local hasDoubleJumped = false
local oldPower
local jump_multi = 1.3


function onJumpRequest()
	if not character or not humanoid or not character:IsDescendantOf(workspace) then
		return
	end

	if canDoubleJump and not hasDoubleJumped then
		print("DOUBLE JUMP CAN HAPPEN")
		hasDoubleJumped = true
		humanoid.JumpPower = oldPower * jump_multi
		repeat StateTracker.State = "onJumping" until StateTracker.State == "onRunning"
	
	end
end

local function characterAdded(new)
	
	hasDoubleJumped = false
	canDoubleJump = false
	oldPower = humanoid.JumpPower
	
	Animation = Instance.new("Animation")
	Animation.AnimationId="rbxassetid://5918176410"
	FlapAN = humanoid:LoadAnimation(Animation)

	
	State.Value.Changed:Connect(function(old, new)
		if StateTracker.State == "onRunning" then
			print("Running check Good")
			canDoubleJump = false
			hasDoubleJumped = false
			humanoid.JumpPower = oldPower
			humanoid.PlatformStand = true
		elseif StateTracker.State == "onFreeFall" then
			print("Freefall Check Good")
			wait(.1)
			canDoubleJump = true
		end
	end)
end

if player.Character then
	characterAdded(player.Character)	
end

player.CharacterAdded:Connect(characterAdded)
UIS.JumpRequest:Connect(onJumpRequest)



while 1==1 do
	print(humanoid:GetState(Enum.HumanoidStateType),"AND", StateTracker.State)
	wait(.2)
end

You’re trying to index the Value, of the StringValue… Not the StringValue… Aka you’re trying to get a .Changed event from a String.

Try this instead;

State.Changed:Connect(function()

I hope I helped :slight_smile:
