BindableEvent Not Working

Help and Feedback Scripting Support
1

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I’m using a BindableEvent to send two arguments from one LocalScript (located in a ScreenGUI) to another LocalScript (in PlayerScripts). This will cause the camera to move smoothly over to a new subject.

  2. What is the issue? Include screenshots/videos if possible!
    The issue is that there are no errors, and I can’t find the problem. I’ve placed a “print” in the connection but found no output.

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have double-checked the hierarchy and tried different variables. I’m not really sure what else to try. Some similar posts have been fixed with the solution regarding the fact that the BE was fired before a connection could be made, but I doubt that is the case, as the first time it’s fired, it’s well into the game.

-- Script A

local function changeCamSubject(subject, newFOV) game:GetService("ReplicatedStorage").Tutorial.ChangeSubject:Fire(subject, newFOV) end

-- There's a bunch of code between these lines, but it all runs fine!

changeCamSubject(workspace.KingNoob, 3)

-- There's also a bunch of code after this that runs fine as well.

-- Script B

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local tutFile = game:GetService("ReplicatedStorage").Tutorial

plr.CharacterAdded:Wait()

local char = plr.Character
local cam = workspace.CurrentCamera
local zoom = 100
cam.FieldOfView = 10
cam.CameraType = Enum.CameraType.Scriptable

local newSubject = false

while true do
	if newSubject == true then
		break
	end
	newSubject = false
	game["Run Service"].RenderStepped:wait()
	if char then
		if char:FindFirstChild("Head") then
			cam.CFrame = CFrame.new(Vector3.new(char.Head.Position.X+zoom,char.Head.Position.Y+zoom,char.Head.Position.Z+zoom),char.Head.Position)
		end
	end
end

-- Switching subjects tween & follow

tutFile.ChangeSubject.Event:Connect(function(subject, newFOV)
	print("Switching subjects") -- Not printing; nothing after this runs (seemingly)
	newSubject = true
	game["Run Service"].RenderStepped:wait()
	if subject:FindFirstChild("Head") then
		
		local tweenService = game:GetService("TweenService")
		
		local goal = {}
		goal.CFrame = CFrame.new(Vector3.new(subject.Head.Position.X+zoom,subject.Head.Position.Y+zoom,subject.Head.Position.Z+zoom),subject.Head.Position)
		goal.FieldOfView = newFOV
		
		local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Sine, Enum.EasingStyle.InOut)
		
		local tween = tweenService:Create(cam, tweenInfo, goal)
		
		tween:Play()
		
		wait(1)
		
		newSubject = false
		while true do
			if newSubject == true then
				break
			end
			newSubject = false
			game["Run Service"].RenderStepped:wait()
			cam.CFrame = CFrame.new(Vector3.new(subject.Head.Position.X+zoom,subject.Head.Position.Y+zoom,subject.Head.Position.Z+zoom),subject.Head.Position)
		end
		
	end
end)

Simple thing. This is because you have a “while true do” loop running in script B before you do tutFile.ChangeSubject.Event:Connect(). Therefore, the script is never going to get to this Bindable event connection since it is stuck in a while true do loop.
