How Unity works: the engine under your game

Stop fighting the engine and start using it. Learn why Unity is built on composition instead of class hierarchies, exactly when your code runs across Awake, Update, and the physics loop, how prefabs and serialization decide what survives to disk, and why physics runs on its own 50Hz clock. Finish able to explain the bugs that stump most Unity developers: the field that keeps resetting, the object that tunnels through walls, and the script that mysteriously never runs.
