iTween is an animation library I created which focuses on the premise of \u201cminimum input for maximum output\u201d to make your life easier when it comes to shaking, spinning, moving, fading, coloring, controlling audio, fading cameras, and just about everything else you can think of in Unity.<\/p>\n

\"\"<\/p>\n

At it’s core, iTween is an interpolation system that takes one value and animates it to another over a given amount of time. Where iTween shines is in its action-specific syntax that frees you from a production or coding mind-set and places you in more of an action-movie director position. At the end of the day iTween allows you to command, point, and lovingly coerce, while speeding up nearly every facet of your development process without sacrificing production value.<\/p>\n

But I can already do these things by…<\/h4>\n

\"\"<\/p>\n

Now, before we dig into the \u201chow-to’s\u201d of iTween let’s answer the \u201cwhy\u201d behind it’s existence. As the saying goes, \u201cthere’s more than one way to skin a cat\u201d and getting things to come alive in Unity is no exception to that rule. You can animate in external 3D applications or with Unity’s built in animation timeline; You can utilize JavaScript, C# or Boo and tackle things through pure, monotonous code; You can realize that you sit somewhere in the middle of these talent spectrums and ponder if you can afford the cost of someone who knows what you don’t. Now don’t get me wrong, before I show you proof of it’s abilities, I want to make it known that iTween is NO slouch when it comes to creating powerful results; simplicity does not equal simple in this case. In fact it’s been battle-tested by big and small game studios, follows the solid foundations of tweening libraries in the Adobe Flash world, and my son thinks it’s cooler than sliced bread. The bottom line is iTween is efficient, fast, simple and fits into nearly every project for use in simply adding pizazz all the way up to powering fundamental game mechanics and systems.<\/p>\n

Ok, I’m still here. Where do I start?<\/h4>\n

iTween is available for download from http:\/\/itween.pixelplacement.com<\/a>. iTween is a single C# file that can be used with ANY of the programming languages that Unity supports, as well as all versions of Unity. If you plan on using JavaScript or Boo you will need to create a \u201cPlugins\u201d folder (if you don’t already have one) in your \u201cAssets\u201d folder for iTween to live in. If you plan on using C# you can place it anywhere you want within your \u201cAssets\u201d folder. That’s it for installation; I told you \u201cminimum input for maximum output\u201d.<\/p>\n

Hello World!<\/h4>\n

Before we get into actually using iTween there’s a few basic things I want to point out:<\/p>\n
