# Animations

There is no official animations implementations in Enoria. However, every Enoria widget is a normal GUI Object (`Frame`, `TextLabel`, etc.). These can be animated with the `TweenPosition` or `TweenSize` functions. The simplest way to get a widget as a Roblox GUI object is to give it a name and to get it with the `GetElementByName` function of the `Context` object.

For instance, we have a menu with a play button that we want to hide (with slide animation):

```lua
local e = require(game.ReplicatedStorage.Enoria.Enoria)
local Widget = require(game.ReplicatedStorage.Enoria.Enoria.Parent.Widgets.Widget)

local Menu = {}
Menu.__index = Menu
setmetatable(Menu, Widget)

function Menu.new(context, title)
   local self = Widget.new(nil, nil, context)
   setmetatable(self, Menu)

   self.Visible = true
   self.Title = title

   return self
end

function Menu:Build()
    local tree
    if self.Visible then
        tree = self:BuildTree(
            e.Container({
                Name = "menuFrame",
                Child = e.Column({
                    HorizontalAlignment = Enum.HorizontalAlignment.Center,
                    Children = {
                        e.VerticalSpacer(16),
                        e.TextLabel(self.Title, { Class = "title" }),
                        e.Container({ Size = UDim2.new(0, 0, 0.5, 0), Class = "transp" }),
                        e.TextButton("Play", {
                            OnClick = function()
                                self.Context.GetElementByName("menuFrame"):TweenPosition(
                                    UDim2.new(1, 0, 0, 0),
                                    Enum.EasingDirection.In,
                                    Enum.EasingStyle.Sine,
                                    0.5,
                                    true,
                                    function()
                                        self:SetState(function()
                                            self.Visible = false
                                        end)
                                    end
                                )
                            end,
                            Class = "button"
                        })
                    }
                })
            })
        )
    else
        tree = self:BuildTree(
            e.TextButton("Open", {
                OnClick = function()
                    self:SetState(function()
                        self.Visible = true
                    end)
                end,
                Class = "button"
            })
        )
    end
   

   return tree
end

return Menu

```

At line 23 we give the menu Container a name. Then, at line 32, we can grab it by it's name and animated.

{% hint style="info" %}
The last parameter of TweenPosition is a callback function. In this example, we set the state to make the menu not visible anymore. If we decided to put it after the tweening, it would not work since it would set the state before the animation has finished to play.
{% endhint %}
