Bro I can't stress this enough : if you keep making C++ , C# tutorials your channel is going to skyrocket ,and hold on hold on before you say that people are more into py and js now yeah yeah I’ve done it all ppl in the comments have done it all, BUT because C# and C++ tutorials are FREAKING rare . I figured that learning the universal concepts and principles of programming languages and their special features are best served with a pinch of tutorials before you go out there and create your own apps. It can be very frustrating just sitting there and creating stuff without seeing how to make them in the first place. You are freaking life savior with this I swear to God. PLEASE make more videos !!!n

[@nikolaoskonstantinidis3505]

I'm a beginner at C# and unfortunately this is very hard for me to follow for some reason. Something about the explanations don't "click" with me. Maybe I'll try it again at a future time. Appreciate all the hard work you put in it though and the fact that you answer all your comments. Much respect.

[@OttoBotCode]

For a beginner, this is too hard. It's more helpful for people who know properties, inheritance, basic collections, etc. If you know such things, following a tutorial like this one can help you get to the next level. I don't speed up the typing like I did for this video anymore, that's probably another reason why it's a bit hard to follow. Once you get more familiar with C# and you want to create a small project, definetely come back here (or perhaps check out my Snake tutorial) and give that a try. Thanks for your comment! 😊

Well, I'm still in the 'learning to code phase' but I just finished my first iteration of Tetris which I coded with JavaScript. Wow, at a certain point I thought I was going to lose my mind because I ran into so many issues, but somehow it's 95% finished now. So, seeing your vid thumbnail, I thought I'd come and learn something. My code is about 4 times the size of yours. I've got a thing or two to learn as yet. It's fascinating to see how you handled the dropping of non-full rows after clearing 'x' amount of rows. That whole process gave me massive headaches.

Good afternoon! I have a problem in the code. I am writing on Visual stusio 2017. Everything is clearly written in code, but the O-block is not displayed. It is displayed transparent on the playing field, although it is displayed in the HOLD and NEXT fields.

[@OttoBotCode]

The hold and next fields display the Block-O.png image. On the playing field, an O-block is displayed using four instances of TileYellow.png. I suspect that Tile-Yellow.png is not loaded correctly in your project. Make sure that Tile-Yellow.png has build action set to "Resource" and double check that you have written the filename correctly in MainWindow.xaml.cs. Let me know if this resolves the issue! 😊

I also want to ask about how can you think about what function to create and how would you create it.. for example create a basic function that can be called later inside another function .. how do you think about it? Does this comes from experience and you just instinctively create all the functions in one go? is there a mathematics that can help us create the desired function? Does math function is really important in programming? for example a composite function is that necessary to learn for programming.. i honestly dont know what function to create but you just seamlessly code that without any troubles..

[@OttoBotCode]

What you don't see in the video is the process of planning everything and structured the code to be as easy to understand as possible. There are design principles and standard patterns you can follow to some extent. That being said, there is no substitute for practice. With time you will develop a feel for what "good" code and "bad" code is. How important is math? That really depends on what you want to do. For most projects it's not so important in my opinion. It's more important to think logically and keep the code as simple as possible. BUT the really impressive programs like ray tracers, machine learning algorithms and game engines require a lot of math! 😉

It is possible but you would have to change the code to display your blocks correctly. Also keep in mind that your blocks will be chopped up when the player clears a row.

i want to add a pause Function on it. Can you help? btw GREAT tutorial and worked like charm

[@OttoBotCode]

Sorry I completely missed your comment! The easiest way to add a pause feature would probably be to add a bool isGamePaused to MainWindow.xaml.cs. When the user presses P (or some other key) we set isGamePaused to true if it's currently false and vice versa. You also want to show something on the screen that indicates that the game is paused. When isGamePaused is true, we must make sure that: a) Pressing any key (except P) won't do anything. b) The current block doesn't move down. Stopping the current block from moving down can be a bit tricky, it requires modifying the game loop a bit. The easiest (but maybe not the prettiest) way would be to add a condition like this: if (!isGamePaused) { gameState.MoveBlockDown(); Draw(gameState); } That way each iteration of the game loop doesn't manipulate the GameState when the game is paused. Hope this makes sense and thank you for the kind words 😊

[@user-qf9dg4xx4b]

Inconsistent accessibility: property type 'Position[][]' is less accessible than property 'Block.Tiles'?

i would like to ask question @3:05 does declaring /*Rows=rows; /*is the same as */ this.Rows=rows; /*Columns=columns; /*is the same as */ this.Columns=colums; what does that imply?.. is that mean the class can only have one instance or object?

[@OttoBotCode]

In this case *Rows = rows* and *Columns = columns* is the same as *this.Rows = rows* and *this.Columns = columns* *this* just refers to the current instance of the class. In the case above you don't have to add it explicitly but it is sometimes necessary. If the parameters in the constructor were also called *Rows* and *Columns* then we would have to do this: *this.Rows = Rows* and *this.Columns = Columns*. It does not imply that you can only create one instance of the class. We don't need it but you could create multiple instances of GameGrid. I hope this helps 😊
