Chipmunk 7.0 Release! Free Pro tools!

Postby AndyKorth » Thu Jan 15, 2015 2:37 pm

The Chipmunk 7.0.0 release is complete!

Most notably, we've decided to integrate all of the Chipmunk2D Pro into the free and open source version of Chipmunk2D. We want the ARM NEON optimizations and autogeometry code to be in the hands of as many people as possible. This also allows these features to be integrated into popular engines like Cocos2D.

Have fun!

What's new in 7.0.0:
* All features from Chipmunk Pro are now free and open source! (threaded and NEON solver, autogeometry)
* API: Lots of cleanup to the API naming for better consistency.
* API: Renamed nearest point queries to simply point queries.
* API: Removed many deprecated functions.
* API: Struct definitions have become fully opaque instead of mangling names with the CP_PRIVATE() macro.
* API: Replaced templated accessor functions with concrete ones. Should be simpler to deal with for FFIs.
* API: Optional automatic mass properties for shapes. Calculates the moment of inertia and center of gravity for you.
* API: Optional anchor point for bodies that is separate from the center of gravity.
* API: Added radius parameters to many functions dealing with shapes (moment calculation, initialization, etc).
* API: The convex hull and winding is automatically calculated when creating a poly shape.
* API: Added a cpShapesCollide() function to check overlap of arbitrary shapes.
* API: cpShape filter property to supersede layers and groups.
* API: Collision handlers now return a collision handler struct to make it simpler to set up callbacks.
* API: Wildcard collision types.
* API: The cpArbiterTotalImpulseWithFriction() function was renamed to cpArbiterTotalImpulse(). The old useless cpArbiterTotalImpulse() implementation was removed.
* API: Contacts now store the colliding point on the surface of both shapes.
* API: cpArbiterIsRemoval() to check if a separate callback is called due to a removal and not a true separating collision.
* API: Arbiters now only store one normal per pair of colliding shapes.
* API: cpBBNewForExtents().
* API: Added a concrete kinematic body type to replace the confusing "rogue" body concept.
* API: Added a 2x3 affine transform type, cpTransform.
* API: Added a new debug rendering API.
* MISC: Numerous improvements to the collision detection.
* MISC: cpPolyline structs are passed by reference instead of value. (I've regretted that decision for years!)

And the manual has been updated to reflect all the API changes:
