Re: [Pyode-user] collide2 ?

[<mar...@gm...>]

Add this code in ode.pyx near the end and recompile pyode:

def collide2(geom1, geom2, arg, callback):
     cdef void* data
     cdef object tup

     cdef long id1
     cdef long id2

     id1 = geom1._id()
     id2 = geom2._id()

     tup = (callback, arg)
     data = <void*>tup
     dSpaceCollide2(<dGeomID>id1, <dGeomID>id2, data, collide_callback)

And you will have collide2 funcion :) It will work like ordinary collide 
function just with this special space checking. I did this for me, 
because I too needed collide2 function between two spaces.
