Module: ease

This module allows you to modify values over a given period of time and following different variation curves.

-- A few examples:
--- local t = {x = 0.0}
-- All ease functions return an instance controlling how
-- values change over time, and on what duration:
local instance = ease:inSine(t, 1.0)
instance.x = 10.0 -- x will go from 0 to 10 in 1 second following inSine curve
--- -- It's also possible to do this in one line:
ease:inSine(t, 1.0).x = 10.0
--- -- The returned instance is useful to cancel the movement:
local instance = ease:outBack(someShape, 12.0)
instance.Position = {10, 10, 10}
instance:cancel()
--- -- An optional easeConfig table can be provided when creating easing instances:
local callback = function() print("done animating") end
local config = { onDone = callback }
-- triggers `callback` when done (after 1 second)
ease:inSine(t, 1.0, config)

ease:outQuad(someObject, 1.0).Position = {10, 10, 10}
outSine ( )

Go to target value(s) following outSine curve.

ease:outSine(someObject, 1.0).Position = {10, 10, 10}

easeInstance

An easeInstance is a table returned by all ease functions to provide control over the ongoing animation.

Functions

cancel ( )

Cancels easing when called.

local instance = ease:outBack(someObject, 1.0).Position = {10, 10, 10}
instance:cancel()
