keyframes

Keyframes is a compact and lightweight UI animation module for Roblox based on TweenService.

Installation

Create the module and import the contents of keyframes.lua, then specify the folder in which your animation modules will reside. The default folder path is game.ReplicatedStorage.modules.

local modules = rs:WaitForChild("modules")

Usage

In order to create an animation, create a new module inside of the folder. The name of the module is what the animation will be referred to. Here's an example animation:

local function keyframes(gui)
	return {
		{gui.Frame, "Out", "Quart", 0.25, {BackgroundTransparency = 0.5, Size = UDim2.new(0.5, 0, 0.5, 0)}};
		{gui.Frame.Object, "InOut", "Sine", 0.4, {Position = UDim2.new(0.5, 0, 0.5, 0)}};
		1;
		function()
			print("animation completed")
		end;
	}
end

return keyframes

Tables are keyframes and will play an animation based on the data provided. Keyframes are synchronous, and their arguments are as follows: EasingDirection, EasingStyle, Duration, Properties.

Numbers are delays and will wait for the specified amount of time in seconds.

Functions will execute as they are written.

In the event that you want to pass another table of keyframes to the handler, simply return another table. This is particularly useful in the event that you want to create a keyframe for a hover effect. Here's an example:

-- Hover effect!
local function keyframes(gui)
	return {
		{gui, "Out", "Sine", 0.3, {BackgroundTransparency = 0.3}};
	},
	{
		{gui, "Out", "Sine", 0.3, {BackgroundTransparency = 0}};
	}
end

Methods

The only method that currently exists is keyframes:play(). The arguments for this are instance GUIObject, string AnimationName, [optional] boolean Reverse and [optional] boolean Asynchronous. Here's an example:

keyframes:play(game:GetService("Players").LocalPlayer:WaitForChild("PlayerGui").ScreenGui, "animationName", false, true)
