I'm trying to run the Fox game sample SceneKit code from WWDC2017, but it crashes when calculating the collision bounding box.
// Setup collision shape
let (min, max) = model.boundingBox
Thread 1: EXC_BAD_ACCESS (code=1, address=0x7fffc0000020)
This error only occurs on my M1 iMac, but runs fine on Intel (using Rosetta).
I really want to get started on SceneKit development for M1 Macs so any help would be appreciated.
Could you try the Fox2 sample that is attached to this session? This is from WWDC21, so it might have a fix for whatever issue you are seeing. If you still hit the bug, please file the issue on Feedback Assistant.
I took my 20K app using SceneKit running on an Apple M1 and pruned it down to a 2 line program which fails. It runs on an x86 2013 MacBook pro. To duplicate, make a new CommandLine app and plonk the following lines down.
import SceneKit let _ = SCNMatrix4Mult(SCNMatrix4Identity, SCNMatrix4Identity)
It responds with
Thread 1: EXC_BAD_ACCESS (code=1, address=0x20)
I think this may be the same problem, and hope that it gets you closer to the problem. When I code matrix 4 multiply by hand, then I get a boundingBox bad address fault.
@PAllenKing can you file this as a bug on Feedback Assistant? That is a very good repro case and should make it easy to debug.
