Runtime Revolution and Debrille Software have updated the Arcade Engine for Runtime Revolution, which helps software developers create 2D games for Mac OS X, Windows and Linux.
A free update for Arcade Engine 1.x users, the new 1.5 release includes polygon-to-polygon collision management, line intersection and segmentation points (used for RPG map creation, for example), point-in-polygon testing, left, right or online testing, a reworked interface, improved documentation and an example project.
Arcade Engine costs US$49; for a limited time it’s free with purchases of a new Runtime Studio license. System requirements call for Mac OS X v10.0.3 or later, 128MB RAM and 50MB hard disk space.
