BoolValue not changing

Help and Feedback Scripting Support
#1

So I want the BoolValue to change when the player touches a part, and that part works fine, when I print it it says true, but when another scripts checks the value, it always comes out as false.

HasTouched = model.Part:WaitForChild("HasTouched").Value

Button.Touched:Connect(function()
	if deb == false and HasTouched == false then
		deb = true
		print(HasTouched)
	end
end)

So what am I doing wrong?

Is your script a local script? It needs to be a serverscript. Server scripts can’t see changes made by clients. If you need it to be done via a local script, fire an event and change it on the server.

#3

You’re only retrieving the value once. You should either put HasTouched in the Touched event’s hooked function or reference the BoolValue, then use HasTouched.Value == false or not HasTouched.Value in the condition.

#4

Try this:

Has touched = model.Part:FindFirstChild("HasTouched")

Button.Touched:Connect(function()
    if deb == false and HasTouched.Value == false then
        deb = true
        print(HasTouched)
    end
end)
#5

You never set BoolValue to true you only set debounce variable to true.

This:

If you print out HasTouched, it just prints “true”. HasTouched doesn’t refer to the BoolValue instance you want to link it to, HasTouched is just a local true or false variable here.

HasTouched should refer to the BoolValue instance instead.

local HasTouched = model.Part:WaitForChild("HasTouched")


anEvent:Connect(function()
    HasTouched.Value = not HasTouched.Value
end)

Summary, the HasTouched in your script is just a local variable and not the BoolValue. Your script just sets the local variable’s value to the BoolValue’s current value. Hope this helped!

You do not need a BoolValue for this, simple create a variable:

local Debounce = false

Then, we can implement a debounce system:

local Debounce = false
local DebounceTime = 1 -- In seconds.
local Debounces = {} -- Our debounce dictionary

local Players = game:GetService('Players')
local Workspace = game:GetService('Workspace')
local TouchTrigger = Workspace.Part

TouchTrigger.Touched:Connect(function(Hit)
	local Player = Players:GetPlayerFromCharacter(Hit.Parent)
	if Player then
		if Debounces[Player] then 
			-- Accessing the player instance is faster than accessing its properties, ex Player.Name.
			return
		end
		Debounces[Player] = true
		
		-- Do whatever you'd like to.
		
		wait(DebounceTime)
		Debounces[Player] = nil -- There's no need to keep this in the memory, so we're setting it to nil instead of false.
	end
end)

This is a player-based debounce.
Just some pseudo code though – feel free to edit.

Well, I didn’t show the entire script, only the things necessary for this thread, but I do need a BoolValue, luckily @g_captain helped me spot the issue.
Thanks anyway.
