PRAction is a GameMaker Studio 2 (GMS) module created by Prismatic Realms, Inc. It is an action/animation system that is similar to a tweening system, but is so much more than that. At its very basic level, PRAction allows you to modify an object's properties from one value to another over time, but it takes this concept several steps further. The idea is that you create "action" objects, each of which represent a specific object property changing from one value to another over a given amount of time. Then you can package any number of these actions together into complex groups and sequences that, when played by a object, will be executed like an action script from a movie.
