Bug Reports Engine Bugs
#1

Reproduction Steps

  1. Create an ImageLabel and name it “Img”
  2. Run this on a LocalScript:
local Players 	= game.Players
local Player 	= Players.LocalPlayer
local PlayerGui = Player.PlayerGui
local Gui 		= PlayerGui:WaitForChild("ScreenGui")
local Img 		= Gui.Img
local START_POSITION = UDim2.new(0, 0, 0, 0)
local GOAL_POSITION = UDim2.new(1, 0, 1, 0)

Img.Position = START_POSITION
Img:TweenPosition(
	GOAL_POSITION,           -- Final position the tween should reach
	Enum.EasingDirection.In, -- Direction of the easing
	Enum.EasingStyle.Exponential,   -- Kind of easing to apply
	5                       -- Duration of the tween in seconds
)
  1. Test changing Enum.EasingStyle also to Circular (9) and Cubic (10)

Expected Behavior
The tween animation should work

Actual Behavior
The tween animation only works for Enum.EasingStyle from 0 to 7.

Try using game.Tweenservice and TweenInfo.new(), despite the fact that tweenservice is commonly used on parts, it can be used on UIs as well. so try something like this

local Img = game.Players.LocalPlayer.PlayerGui.Gui.Img
Img.Position = UDim2.new(0,0,0,0)
local tweenInfo = TweenInfo.new(
5,
Enum.EasingStyle.Exponential,
Enum.EasingDirection.In
)
game.TweenService:Create(Img,tweenInfo,{Position = UDim2(1,0,1,0)}):Play()

I know.
But the topic is about GuiObject | Roblox Creator Documentation.

Those tweening styles are currently limited to internal use, I’m not sure why but it’s been that way for years.

#5

No, they will work with Tweenservice.

#6

There was a bug report for this issue before, and they likely won’t be fixed. You’re supposed to use TweenService instead of TweenPosition and TweenSize, which works with these EasingStyles.
