RAIN Overview:

Today we launch the latest version of RAIN, the development tools of the Sentio Platform. This version of RAIN is the most streamlined, optimized, and beautiful version to date. Even if RAIN’s looks are the first feature you notice— the massive improvements to our wiki documentation and new Getting Started tutorials will help you dig deep into everything RAIN has to offer.

Below is the details release notes about the newest version of RAIN.

RAIN 2.1 Release Notes

Upgrades:

- Wiki documentation has been significantly upgraded. Click on the red question mark symbol in any RAIN Editor and you will be linked to relevant help from the wiki.

- Numerous performance improvements throughout RAIN.

- MoveLookTarget positions are now displayed in AI memory, making movement debugging easier

- Mecanim Motor UI cleaned up, now only shows parameters in use.

- Navigation Target range is now used as a close enough distance when moving to the target

- Behavior Tree nodes are now placed inline when added through the Behavior Tree editor, rather than at the end of the current container node.

- gameobject(“objectname”), navigationtarget(“targetname”), and waypoints(“waypoint route/network name”) as functions usable in Expressions.

Bug Fixes:

- Fixed bugs with Expression evaluation

- Fixed unary operators not parsing correctly in Expressions

- Fixed an issue with waypoint patrol routes not resuming properly after interruption

- Fixed an issue with jitter when using both Move and Face targets simultaneously

- Fix for importing behavior tree XML (was not saving).

- Removed check for incorrect animations as it won’t compile for WP8.

- Fix for close enough distance (on Move node) not being used in some cases.

- Misc. editor fixes and stabilization

Other:

- The RAIN Editor now sends an anonymous ping to the update server once every 24 hours. No personal data is sent, only the RAIN version #, Unity version #, and unique device id.
