This was amazing, omg! I'm actually walking away from a tutorial understanding! Usually I gotta like watch a few times or somethin to get it, but the code and concepts was explained well! Also, you mentioning Class Inheritence a lot helped me actually understand that too. I've never been able to get it, but it makes a lil more sense to me now. Thanks man, this was awesome!

I totally agree such a very well constructed video! amazing tutorial made my day, thank you so much :)

What I dig about your approach here is you actually take the time to explain the why and the theory first, as opposed to just providing code for people to copy with no understanding. Great stuff.

Coming from an AI background, this is really good. I think a lot of programmers gloss over things, but this was really thorough. I also like that you showed how complex numerous conditionals can be, which is a common issue in development, this will teach people to recognize when to use a State Machine. I myself have a very complex player controller, which is only going to get more complex, and I look forward to your next tutorial.

Honestly, what a great vid. I finally understand how it works after 5 hours of trying to understand state machines

this is the most clear and soothing explaining i ever saw on youtube, thank you for the video

just the absolute exemplary game dev tutorial video, I came in not knowing much about states and with my notebook busy, have left with the ability to go integrate State Machines into my own game. Thank you so much

I was reluctant to use this system on my already-made code, but my God, it's a blessing to use!

been using the unity animator as a finite state machine since I could never wrap my head around how this pattern worked. the animator makes it super messy when you have 24+ different states but surprisingly it worked... you definitely explained this pattern much better then any other tutorial I've seen. cant wait to try this out in my next game!

This actually got State Machines through my skull! Thank you for your effort and love for this! ❤

Really incredibly work with the video. I was having SO MUCH trouble trying to get my states to be able to reference whatever is managing the states to change it but this made it really simple to understand. These videos are 10/10 quality.

Gotta be one of the best explanation I've seen

Honestly, I think this is the best tutorial about state machines! Your edition, examples and code are completely understandable at first view! Thank you very much

It really worked for me after I look and try some tutorials, yours is the one that worked. Owe you a lot.

Finally I understood state patterns which i was struggling to understand. Thank you mate, heart to you❤❤❤

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.

probably best tutorial i'Ive seen overall not just unity, literally god tier!

I am only half way through but just paused to say, awesome tutorial dude! Really clear and well explained, thanks!

Awesome tutorial, thank you. I had used state machines before, but the tutorial I followed placed all of the logic for each state in a single class. This is so much better. It feels like spring cleaning.

I think this is bang on what I'm after! I'm writing a Tower Defense game. 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.
