The issue presents itself by the fourth tap, as the gradient will then appear outside of the SKLabel frame. A tap down on the scene will iterate the text of the SKLabel though 3 strings of different lengths. The effect node has a simple SKShader attached which produces a gradient effect across the frame of the SKLabel. It consists of an SKScene, with an SKEffectNode added to it and an SKLabel added to the effect node. I've prepared the following playground example which allows for reproduction of what I believe to be a bug. This happens when the frame of the effect node's subview is changed. Currently my copy still contains nodes even though I don't display them and only require read access.Īs of iOS 16, I am seeing strange behaviour in SKEffectNode where the attached shader appears to be affecting an area that is outside the accumulated frame. int GetNewestTrailWithParticleId (int particleId) Gets the newest trail following the particle id. If the trail is already dead or doesn't contain the particle id -1 will be returned. int GetOldestTrailWithParticleId (int particleId) Gets the oldest trail following the particle id. A fast & simple way to copy these parameters from all nodes into a normal array would do. Creates a trail and assigns it to a particle. I need access to things such as position and velocity for each node and there can potentially be 300 of them. They could even be copied prior to going into the background thread.

With my code I am copying 2 arrays of nodes and use those copies in the background thread/s. I'm getting the impression that nodes can only be accessed from the main thread. I tried removing the from the parameter 'goalSpeed' and it made no difference - the error still occurred on it. A number of its parameters were also Published variables. the 'Vehicle' type is an ObservableObject. Override var focusItemContainer: UIFocusItemContainer? ) //Sort into positional order, 000 - 999.999 Some of the nodes cannot be focused then anymore, and the focus just jumps to random nodes, and not the one in which direction I swiped to. So then I tried to just set the SKScene's view, the parent environments focus item container, an empty view and more as the SKScene's focusItemContainer - this fixed the crash, but the focus behaves quite randomly. Now, with tvOS 16, the app crashes with the following error:įocus item RandomSKSpriteNode has a parent focus environment of MySKScene but this environment does not provide a container for focus items. Before tvOS 16 everything worked correctly, I could move around with the remote and focus all items in the correct way.
