Hi Great tutorial.
I followed along and learned a lot about realitykit. I lasted try ARKit in version 2. I have two issues I wanted you to help with.
The first is more a usdz issue. sketchfab now supports export to usdz, so I downloaded the following file to add a fourth instrument.
Credit for Djembe Drum, Djembe Goplet Drum - by aqpetteri - https://sketchfab.com/3d-models/djembe-goplet-drum-572d364642434810abd1fa7cfb6e7782
In Xcode i set the scale to 0.1,0.1,0.1 on its local space as it's huge. It fits in the scene with the other instruments. However it moves after the animations ends. (up and towards camera). How do I address this issue? I suspect it will happen frequently if I am importing models from the web.
The next issue I had was a question. I have a loading animation playing when the models are being loaded. I would like to continue playing the animation until the objects are placed in the scene. Is there an event I can subscribe to end my animation when objects appear? I couldn't find anything, I tried SceneEvents.AnchoredStateChanged.self but this is fired a lot and crashes a second time at anchorCancellable?.cancel()
//MARK: I want to know when my objects are visible.
var anchorCancellable: Cancellable? = nil
anchorCancellable = arView.scene.subscribe(to: SceneEvents.AnchoredStateChanged.self, on: anchor) {
(event) in
if event.isAnchored && anchor.children.count == 4 {
anchorCancellable?.cancel()
self.loading = false
self.controlLoadingAnimation()
}
}
The reason I still want the animation to play is I've been testing in a busy room and it takes a while to find a plane to place objects on ( I think that's what's happening)
Again thanks for the tutorial.
