You're the next level, you're my goal, I already got to a high level as a flutter Dev and I was beginning to relax, but your videos just 🤯...You're mental Mitch

bool checkCollision(Direction direction) { // loop through all direction index for (int i = 0; i < currentPiece.position.length; i++) { // calculate the index of the current piece int row = (currentPiece.position[i] / rowLength).floor(); int col = (currentPiece.position[i] % rowLength); // directions if (direction == Direction.down) { row++; } else if (direction == Direction.right) { col++; } else if (direction == Direction.left) { col--; } // check for collisions with boundaries if (col < 0 || col >= rowLength || row >= columnLength) { return true; } // check for collisions with other landed pieces if (row >= 0 && gameBoard[row][col] != null) { return true; } } // if there is no collision return false return false; }You can update checkCollision to fix collision with other piece

Hey Mitch. Great content. I hope you read this message. Lot of your viewers(beginners) face this problem. All of pieces are not landing on top of each other. We need it to be solved.

Clever👏 you’re clever Mitch✅ not just coding….genuinely inspired teaching 👌

That's really amazing🔥 Good work🎉

Very nice. I really enjoyed this tutorial. Beginner Flutter programmer here (but relatively experienced in scripting). One small problem in the tutorial though. At 19:32, your blocks are stacking, but the checkCollision method you outlined in 15:54 didn't have any code to detect collisions with other pieces. In between, you didn't mention any update to this method. Thankfully, due to your excellent explanation of your code, I figured out what I needed to add to achieve this.

I am very impressed with the details, i was already thrilled, but when you added the rotation i wanted to go and pop the fireworks, thats how happy i am. I want one day to reach your level of sofistication.

Great video! I found out that instead of using a Map to get the piece (Tetromino) color, using the enhanced enum as in: enum Tetromino { L(Colors.orange), J(Colors.blue), I(Colors.pink), O(Colors.yellow), S(Colors.green), Z(Colors.red), T(Colors.purple); const Tetromino(this.color); final Color color; } then we just get the current piece color using currentPiece.type.color.

Thanks a lot, Mitch. You inspire me a lot.

This was a short n sweet tutorial. I learned a lot.

I don't know why but I am in love🤩 with your Channel content. Great Content as always 💯💯

May I respectfully request you to make a tutorial video for Flutter Flame Game. I am really excited for your tutorial.

Awesome tutorial, keep up the good work!!!!

that's cool, only with flame it seems to me it would be much less code without the need to count collisions ,

Best in class 💜

You work great and amazin in flutter continue I support you 🎉

great sir

great tutorial 😄

Great as always

You are next level mann🙌🏻🙌🏻❤

19:46 My pieces are not stacking on top of each other like this and all are landing at the bottom and then overlapping. Any idea what I might have missed?

Yes, we need more help in the business logic part like implementing Collision detection system, movement and rotation. I understand whats going on, but I cant generalise the logic and implement in other projects, that seems pretty hard to get. Maybe some video just about the business logic involved in games would be wonderful!

Loved the video. THANKS💜

This is really cool ❤thanks so much bro

Great work Mitch!! .. Please Mitch, can you make a video on how to connect flutter project to unity? 🙏

just beautiful👌

good job . thank you brother

Def. Going to try this one, thanks 👍

you're awesome

Thanks 🎉 That's great 😍 please can you make tutorial about coloring game and drag-and-drop game

i wonderful u r teaching is so nice .

Good job!

Hi, Mitch! Can you make a video on how you set up your Flutter environment? Can you make one for Windows? And if not, what emulator are you using? Thanks for this wonderful video!

Thank you so much❤...

💜

Great Job Thanks

thanks

❤🔥😍❤️ well done ❤️

💜💜💜💜💜

This Tetris tutorial was really great :D. I am kinda beginner.. so I tried to copy the exact same code as mentioned in the video, but still my every tetromino is landing on the bottom only, instead of landing on top of the below tetromino block. :(. Can anyone help please?

where are you absent You don't upload many videos anymore. We missed your new ideas, so design and programming🎉🎉🎉

Hi, their is one problem that's if we completely fill the last row as end row then after that we just skip 2-3 lines and then make the row fill then it just show error , how can I solve that .

The tetrominos stop falling after couple of times, can anyone help?? I am stuck at it for 4 hours...

Bro i do but i have problem for loop is not stop when chackland void what is solution

any video about horizontal bar chart?

Hey can you show how to install and begin?

Hey mitch can u check why the pieces are not dropping after sometime cause its occuring randomly

make a video developing an application like 99 Taxi and creating API and Database without Google's Firebase

I tried to add code in createNewPiece but it’s still stuck in checkLeading how to fix bro

I lost hope in learning flutter😭but i will watch your videos 🎉

My blocks for some reason going through each other. Checked code and it looks identical, do you have any idea what might be wrong?

Has anybody solved the Range Error? when a line is full in the middle of the game board this Range Error shows up

Another one

My game is not running properly. When I play the game, the pieces stop in the first row and the game ends automatically. Another problem is that when the pieces fall on top of each other, the missing first piece is overwritten. Someone help me

Hey Mitch! Great Content as usual. Everything works fine but I am getting RangeError when a line is cleared from the middle of the screen. Any idea why this might be happening?

Hi, the rotation isn’t working for me. I tried everything you said and I can’t seem to find the problem. Can you please help me?

anyone can shared source code with me, pieces are stop after couple of time, how to solve this error please help me

Superb but do your hard work as open source

31:26 bru im getting range error in line 156 (RangeError (index): Index out of range: index should be less than 10: 14) can you help me boss?? thanks a lot

Has anybody solved the Range Error for this? It happens when a line is full in the middle of the gameboard...

can someone help me please , when i rotate the letter Z it doesn't rotate correctly , that's the part of Pieces code i copy it like Mitch: case Tetromino.Z: switch (rotationState) { case 0: newPosition = [ position[0] + rowLength - 2, position[1], position[2] + rowLength - 1, position[3] + 1, ]; //check that the new position is valid if (piecePositionisValid(newPosition)) { //update position position = newPosition; //update rotation state rotationState = (rotationState + 1) % 4; } break; case 1: //assign new position newPosition = [ position[0] - rowLength + 2, position[1], position[2] - rowLength + 1, position[3] - 1, ]; //check that the new position is valid if (piecePositionisValid(newPosition)) { //update position position = newPosition; //update rotation state rotationState = (rotationState + 1) % 4; } break; case 2: newPosition = [ position[0] + rowLength - 2, position[1], position[2] + rowLength - 1, position[3] + 1 ]; //check that the new position is valid if (piecePositionisValid(newPosition)) { //update position position = newPosition; //update rotation state rotationState = (rotationState + 1) % 4; } break; case 3: newPosition = [ position[0] - rowLength + 2, position[1], position[2] - rowLength + 1, position[3] - 1, ]; //check that the new position is valid if (piecePositionisValid(newPosition)) { //update position position = newPosition; //update rotation state rotationState = 0; } break; } break;

hello, same problem i toke the solution from the comments, it worked , but stoped when [row] is negative so i tried that modification with [row.abs()], if (col < 0 || col >= rowlenght || row >= columnlenght || board[row.abs()][col] != null) { return true; it work for the moment

does any one has the source code

🥰🥰🥰🥰🥰🥰🥰

Awesome as usual 🎉
