Problem using RealityComposer about multipeerhelper HOT 7 CLOSED

@maxxfrazer Hi, When I say animations I mean the animations in a rcProject, I will send this problem to Apple. My rcProject is 180MB... Thanks very much for your reply!

from multipeerhelper.

I did more test and found that this crash only happens when rcProject activities have an animation. If an activity only does hide and appear (without any animations), all things work fine. But if it contains scale, rotate or other animations, this crash will happen. Do you have any ideas? I think it's a bug in RealityComposer but I am not sure...

Hi @xinnai, I'm glad you like this repo!
I don't know what this issue could be, but there are several similar issues on stackoverflow that may help you such as this one potentially?

Is that post function something you've created or does that come straight from the rcProject?

BTW when sending data; I find it simpler to just use JSONEncoder and JSONDecoder, it can be clearer when debugging than bringing it in as an NSDictionary. See here for an example:

That post function comes from the rcProject file so I've no idea, maybe this bug will be fixed by apple some day.
That's really kind of you to tell me about JSONEncoder and I will improve my code immediately.

BTW I found your code has memory issue and will crash when connectting a big rcProject. I think this because of the high frequency synchronization make a rapid increase of memory. I don't think it's your code's problem but I think I could let you know, thanks again!

@xinnai that's interesting about the memory issue, how big is your rcProject?
Without knowing much about the specific problem, could it be that both users are creating the entire scene and then sending it to each other over synchronization? I've had problems syncing USDZ files over the network and have opened a FB request to Apple. If you can replicate your issue they might help you out by responding to FB, they seem pretty good at responding to RealityKit feedback so far.

@xinnai looks like RealityKit animations work fine, I added one to the example project on the branch dev

I'm going to close this because it seems like it's most likely a RK issue, not an issue with this framework
