The ball spawns\r\n\r\nThe problem is that the table script starts running before `Player.Start` is called and nothing happens because `CoilPlayer.HandleCoilEvent` does not yet observe `IGameLogicEngine.OnCoilChanged`. This might be non-deterministic as well because the order of in which `Start` is called on MonoBehaviours is. Not sure how it is in Visual Scripting.","author":{"url":"https://github.com/arthurkehrwald","@type":"Person","name":"arthurkehrwald"},"datePublished":"2024-11-26T11:55:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/9/VisualPinball.Unity.VisualScripting/issues/9"}
