I think the state pattern makes sense as the pattern to manage the various stages: Area Creation, User Tower Setup, Wave of Enemies, Game Over/Wave complete etc. I've done a similar thing to this before, but using one massive MonoBehaviour class that handles every single state. So I really like this approach. Thank you for making it so clear :)

Your tutorials are superior every tutorial out there not only because you are a good teacher, but you also visualize what you're explaining and to someone like me, visualizing something is a LOT easier to understand than just typing code telling you what you need to create a state machine. I have seen so many tutorials where they just type code telling you that you need these lines of code because you just need it but never say WHY. I am someone who always ask myself in my head "why am I doing this and not that? what exactly does this mean?" and you answer those questions.

So I want to chime in here and say that there is one thing that I think should be done differently. In this example the AppleStateManager is creating four new instances of Apple states FOR EACH APPLE in the level, If I were to have a map of 1000 apples then there would be 4000 instances of appleStates present all doing the exact same thing (which is nothing other than taking up memory). In this case since none of the individual states are storing any type of data you could make the states static, that way you dont need to create new references. The only data needed is the current state value within the AppleStateManager Other than that great job on the video. Will you also be covering the Unity Animator State Machine?

@@lhorbrum1818 This is going to be a long one, So in the video AppleStateManager was made to hold an INTERNAL public variable of each state type, which was then populated with a NEW state object. Creating the apple object we have: the apple gameObject, the apple's State Manager object, and the 4 apple state objects within that manager. Resulting in a total of at least 6 objects (1 + 1 + 4) stored within the computer's memory. Now that was for a single apple in the level, as an example let's imagine 10 apples in the level. We have 10 gameObjects made by unity, each object has it's own manager 10 * 1 for a total of 10 managers in the scene, and EACH manager has its own set of 4 state objects (10 * 1 * 4) for a total of 40 state objects. All together the level would have at least 60 objects (10 + 10 + 40). Now here is the thing, the way @iHeartGameDev made the state behaviors, requires that you pass in a AppleStateManager reference as a parameter, which allows the behavior to modify anything within that manager. This means that it is possible to have A SINGLE state exist in the entire level and have all managers request the behavior from it so long as they provide who it was that made the request/needs modification. By doing this we can reduce the 40 state objects down to just 4 objects, reducing memory usage to at least 24 (10 + 10 + 4). A 36 object reduction. Now imagine instead we have 10,000 apples!!!! We would be going from 60,000 objects (10,000 + 10,000 + 40,000) to 20,004 objects (10,000 + 10,000 + 4) A wopping 39,996 object reduction. Usually when creating a single/few unique objects in your game that have its own unique set of states (Like a player object or a game instance manager) you dont need this type of optimization. Since this video made the states be on what appears to be a common object, an apple, and the level requirements could have lots and lots of apples to be loaded at one time then this optimization would be required, also it's just good practice to keep in mind. One limitation to creating static state object references is that any data that is stored within the state will be shared across all other objects. Example: State has a timer variable of 50 seconds that counts down on update. New manager is created using same state, now both objects are updating state at same time counting down faster, both objects finish the counter at same time despite second object being created latter. A way around this is to store countdown variable within manager object and have the static state's method modify it using the passed in reference parameter.

As an experienced C# developer, I can say this is a very thorough, clear and correct explanation, good job! One optimization (depending on the context) would be to not retain the created state in the Manager. Instead, having each state as a Singleton will load your game faster since you will have only one version of each state to instantiate at startup. Simply call appleRottenState.Instance in the SwitchState method. It will instantiate your object when needed and keep it in memory in case there's another SwitchState called. Another choice would be to not keep them in a Singleton and simply instantiate them each time a switchState is called. It all depends on the object itself (complex or not, easy to instantiate for the machine or not) but it's worth noting and make the Manager slightly shorter.
