The RK Unity Toolkit is an open source library of extension methods and tools that make solving many common problems cleaner, faster, and easier. Here are some of my favorites:

• Easing Functions - Unity implementations of all the functions described on easings.net. These are very useful for code-based animations and creating polished non-linear behaviors.

• Vector Extensions - A lot of common vector operations like taking the absolute value, clamping, and removing components are tedious and verbose in Unity. These extensions simplify most operations into a single statement that’s easy to read.

• Gizmo Drawing Tools - Debugging 3D math can be really difficult, so to make it a bit easier, I’ve added some tools to draw points and bounding boxes in Unity’s gizmos.
