ChipmunkObjectFlatten Deprecated?

I'm trying to follow along with the Objective-Chipmunk examples, namely the SimpleObjectiveChipmunk project, but I notice that ChipmunkObjectFlatten has been deprecated in 6.0.2?
Can anyone point me in the right direction as to how to get over this issue?
Thanks.

Ah, sorry about that. From the header:
Code: Select all
/// @deprecated since 6.0.2 Use [NSArray arrayWithObjects:] or similar instead.
NSSet * ChipmunkObjectFlatten(id <ChipmunkObject> firstObject, ...) __attribute__((deprecated));
So where you would have done:
Code: Select all
chipmunkObjects = [ChipmunkObjectFlatten(a, b, c, d, e, nil) retain];
Do one of this instead:
Code: Select all
chipmunkObjects = [[NSArray alloc] initWithObjects:a, b, c, d, e, nil];
The Chipmunk Object protocol was modified to work with any nested NSFastEnumeration objects (NSArray, NSSet, etc) instead of only the flattened NSSets that the ChipmunkObjectFlatten() method created. Originally I had created it that way for what turned out to be imaginary performance reasons. So I fixed it to be more flexible.
