My tweens are not playing despite being told to do so

[notsad2 (nots7d)]

my tweens are disobeying orders and i literally have no idea why, this is something i come across for the first time and i am unable to see any errors in my beautiful code

the BackgroundTransparency of both the frames i’ve defined just instantly pop to 1 and the tweens never play, why is this??

local TS = game:GetService("TweenService")
local tweenParameters = TweenInfo.new(
	1,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.Out
)

-- // HEALTH UI
local plrGui = plr.PlayerGui:WaitForChild("PlayerUI"):WaitForChild("Main"):WaitForChild("UI")
local HealthAmount = plrGui:WaitForChild("HealthAmount")
local currentHealth = humanoid.Health
local LowHPUI = plr.PlayerGui:WaitForChild("PlayerUI").LowHealth

-- // STAMINA UI
local StaminaAmount = plrGui:WaitForChild("StaminaAmount")
local Stamina = plr:WaitForChild("Stamina")
local StaminaFullEffect = plr.PlayerGui:WaitForChild("PlayerUI"):WaitForChild("Stamina100")

-- // SOUNDS
local HurtSound = script:WaitForChild("DamageSound")
local LowHealth = script:FindFirstChild("LowHP")
local StaminaFullSound = plrGui.Parent:WaitForChild("StaminaFull")

function ResponsiveHealth()
	if humanoid.Health < 0 then
		HealthAmount.Text = "0" .. "/" .. humanoid.MaxHealth
	end
	
	if humanoid.Health > 0 then
		if humanoid.Health < currentHealth then	HurtSound:Play() end
		
		if humanoid.Health < 30 then
			LowHealth:Play()
			HealthAmount.TextColor3 = Color3.fromRGB(125, 30, 11)	
			LowHPUI.Visible = true
			LowHPUI.BackgroundTransparency = 0.6
		else
			LowHealth:Stop()
			HealthAmount.TextColor3 = Color3.fromRGB(255, 255, 255)
			-- // this does NOT run >:(
			local HealthTween = TS:Create(LowHPUI, tweenParameters, {BackgroundTransparency = 1}) 
			HealthTween:Play()
			
			if HealthTween.Completed then
				LowHPUI.Visible = false
				HealthTween:Destroy()
			end
		end

		HealthAmount.Text = math.floor(humanoid.Health)	.. "/" .. humanoid.MaxHealth
	end
	
	currentHealth = humanoid.Health
end

function ResponsiveStamina()
	StaminaAmount.Text = math.floor(Stamina.Value)
	if Stamina.Value == 100 then
		StaminaFullEffect.Visible = true
		StaminaFullEffect.BackgroundTransparency = 0.6
		-- // NEITHER DOES THIS >:(((
		local StaminaTween = TS:Create(StaminaFullEffect, tweenParameters, {BackgroundTransparency = 1})
		StaminaTween:Play()
		StaminaFullSound:Play()
		
		if StaminaTween.Completed then
			StaminaFullEffect.Visible = false
			StaminaTween:Destroy()
		end
	end
end

humanoid.Changed:Connect(ResponsiveHealth)
Stamina.Changed:Connect(ResponsiveStamina)

bumping since i still didn’t fix this!!!

Wait, shouldn’t ’ completed ’ be connected to function? in:

@notsad2

			if HealthTween.Completed then
				LowHPUI.Visible = false
				HealthTween:Destroy()
			end
		end

and

@notsad2

if StaminaTween.Completed then
			StaminaFullEffect.Visible = false
			StaminaTween:Destroy()
		end
	end
end

[notsad2 (nots7d)]

uh i, i’m not sure what you mean?

[quxplayz (Nadricus)]

As far as i know, ’ completed’ doesn’t return a boolean?

StaminaTween.Completed:Connect(function()
			StaminaFullEffect.Visible = false
			StaminaTween:Destroy()
end)
