Chipmunk 2.5D Physics

An FFI to the Chipmunk 2.5D rigid body physics engine.

(require (planet jaymccarthy/chipmunk))

This module re-exports (planet jaymccarthy/chipmunk/chipmunk-ffi) with a few changes and helpers.

First, cpInitChipmunk and cpResetShapeIdCounter are called.

Second, the following are provided:

(gen-collision-type) → exact-nonnegative-integer?

Returns a unique integer to use as a collision type.

(cpSpaceAddCollisionPairFunc   space             typea             typeb             callback)   →   void

space : cpSpace?

typea : exact-nonnegative-integer?

typeb : exact-nonnegative-integer?

callback   :   (-> cpShape? cpShape? (vectorof cpContact?) cpFloat?     boolean?)

Adds a collision pair function where the callback has less work to do.

(cpSpaceSetDefaultCollisionPairFunc   space             callback)   →   void

space : cpSpace?

callback   :   (-> cpShape? cpShape? (vectorof cpContact?) cpFloat?     boolean?)

Sets the default collision pair function where the callback has less work to do.

(cpvadd x ...) → cpVect?

x : cpVect?

Variable arity cpvadd.
