This page is for features from RAIN{indie} 1.3.4 version.

Our latest RAIN 2.0 version, is available to download directly from our website and currently cannot be downloaded from the Unity Asset Store.

Check out the RAIN 2.0 Features and Download the new version.


Movement

RAIN’s movement, behavior and pathfinding systems work together seamlessly to control Character motion. Use scene waypoints to create paths fast, or take advantage of the automatic recast and navigation grid system for detailed movement. The built-in Behavior Tree editor can help you tie movement to behavior to create patrol, hiding, attack, chase, wander, and other movement behaviors.



Behavior

Whether you are building simple background behaviors or creating complex strategic decision making, RAIN’s behavior system can help bring your Character to life. Create realistic behaviors through the graphical Behavior Tree editor and quickly add movement, animation, sensory awareness, and sound effects. Import, share and reuse previously created behaviors through XML.


Animation

RAIN is the only AI engine on Unity to support Mecanim, with built-in integration between behavior, movement, animation control and the ability to drive Mecanim state machines. Unity Legacy-style animations are also supported, with playback and transitioning support throughout RAIN’s motion systems. RAIN provides easy extensibility for creating and integrating user-defined animation controllers.



Performance

We know that creative vision should not be inhibited by technical constraints, and that’s why RAIN has been engineered to deliver reliable performance, smooth framerate and superb player experience across target platforms.

Ultimately, our intent is to capture the essence of the original artistic inspiration without imposing limits.
