Thank You Very Much!!! I used c# before for one of my exams and i hated it. But now after this project I feel that it is fun to code in this language.

[@lil_fanera]

Thanks for your video, I'm learning programming in C# and it's really helping me. I repeated after you, and then I analyzed the code that you wrote.

[@mooict]

Great job!

Hi ICT. Can i ask u about why my following step by step but my array is not functioning?

[@keivvy3269]

hi, when i try to press the keys to change the directions of the snake, the keys do not work, may i ask know why?

[@reyniercastano625]

That happens when the focus is on another control, key events might not be captured by the form. Go to Form properties and set KeyPreview to true, when done, you ensure that the form receives key events before they are passed to other controls. This allows you to handle key presses even if another control has focus

[@yardleighLanthony]

I had one last question as well, the in Settings.cs. What is the field directions = "Left" for? I was also confused about that as well. Thank you and have a great day.

[@mooict]

Direction == "Left" is the default direction of the snake. You can change it to any of the other directions and it will run in those direction when the game loads up first.

[@yardleighLanthony]

[@johncarmelosaloritos5086]

Thanks for the tutorial Moo, I just wanted to ask how can I reduce the length of the snake?

[@tyshoe]

If you are talking about the default length of the snake, he set his length to 10 by default at 23:31 on line 116. if you wanted to reduce the starting length, thats where you'd do it.

[@bencabilete6408]

Where parts of event arguments to move upward, the snake stop when i press up arrow keys

[@iScreens]

What keyboard switches do you have?

[@mooict]

Gateron Yellows I use mainly.

[@Soax-GameCenter]

When I was starting the game for you the snake moved and you could control it but for me the snake did not pop on the screen when i clicked start. Plz help and explain why it is not working

[@ledschmidt1441]

Hope you still check out the channel..... What is NUTs is, when the game starts, it flips the panel 90 so the snake is running vertical!! I checked all out and nothing... the canvas and panel when viewed from the form window is right, game starts and it flips it 90degrees AND i have no control of the snake unless I hold down two buttons at a time??? Nuts

[@oli9944]

Hello moo. Could you make a tutorial for a grid type of game in windows forms c#? For example, think Zelda 3 (link to the past) but with a grid, so we could later customize it to make turn based games, grid dungeons exploration, grid war strategic fighting, things like chess, etc. Just a simple grid in windows forms which we can then use to make our own customized games!

[@mooict]

I've done a snakes and ladders game using a image grid may be that will help you. It's also a turn based game 👍

[@oli9944]

@@mooict I’ll check it out, thank you!

[@yardleighLanthony]

Good day :), I find your videos really helpful and fun, thank you for that. I just had a question regarding why you named one of the methods "KeyIsUp" and "KeyIsDown"? I am confused about the naming. I am a first-year student and just learning about programming in c# and I apologise if my questions sound dumb but why did you not make a method as well that is called "KeyIsRight" and "KeyIsleft", if I may ask?, and the "e.KeyCode" is a built-in function? for when you press a key if I am not mistaken? Thank you and have a great day.

[@mooict]

Hi, key is down and key is up is created not for their direction but for the process. So the reason is called key is down in this example is because this event will trigger when the keys pressed down and. The key is up will trigger when the keys are released. We can access up down left right and all the other keys on the keyboard from inside of those events and we won't need to make the key is right or left extra events there. Hope this helps you

[@yardleighLanthony]

Hi Yazan, this error is stating that the if statement is trying to compare a boolean with an integer. Is it the part when snake eats the food? If so both the snake[i].x == food.x are integer values in the game, check if this statement is the same on yours.

You will need to add the directions enum to the settings class. It’s explained in the tutorial.

yet another question from me, and i am so so sorry to bother you this much: When i am at that part where we are adding "if (Snake[i].X == Snake[j].X && Snake[i].Y == Snake[j].Y)" { GameOver();} " [this is at 43:10 in video] i get following code: System.ArgumentOutOfRangeException: 'intex was out of range.Must be non-negative and less than the size of collection.

[@reyniercastano625]

That happen when the for loop is assigning values to either X or Y that don’t exist in your snake. Try using the debugging tool to identify exactly where things are going wrong

[@maneharutyunian7430]

I want to write the game with levels and in each level the speed of the game is going to be changed and some obstacles is going to be appeared. I think that there is no need to create new forms for each level, but the modification can be done in general form. Could you help me with that task?

[@whallieoo]

In the "private void button1_Click(object sender, EventArgs e)" section the "KeyCode" command doesn't work for me. Any ideas of whats wrong?

[@mooict]

It's the wrong event for key code. You are doing keyboard event code inside of the mouse click event. Do the keycode inside of the keydown function.

[@whallieoo]

Got ya, thx!

[@julitawojcik9994]

Hi! Thanks for your amazing job. I am thinking of adding a pause button to the program, but the active button is blocking the movement of the snake. Could you give me any tips how to do it?

[@mooict]

Having a pause button will take the focus away from the form. I think it will be better for you to have the pause function linked to a key down event. For example press p to pauses.

[@deadropfurman1694]

Hey mate, i just wanted to know, why doesnt the Timer do anything? I expected that after 40 second the game would be over, but it play indefinitely, or did i mistake about what the timer actually does?

[@mooict]

Hi the timer acts as the main game loop, it runs the entire game including the move Kent of the snake, updating the body of the snake, spawning the food and finally the user controls. The value 49 used in the timer properties is to set an interval so it ticks every 40 milliseconds and each time it will run the timer event. Hope this helps

[@deadropfurman1694]

@@mooict Oh, thanks, it actually does help, i thought about expanding the game (cause my course project demands inheritance), one of the things i thought about was making certain foods that increase movement speed (i suppose the interval will affect that), but if i wanted to add a timer, like a real one for the game duration, where would i put it? Thanks!

Hello, your video really helps me a lot. Just a little question here, is there any way to prevent the overlapping of food on the snake body when the food spawn on the map?

[@comebackguy8892]

Use a while or do-while loop that loops if the food intersects with snake. The food will in other words continue to try and randomize a spawn until it does not touch the snake.

It is to calculate number of parts that fit in the canvas. In my case maxWidth 442 / 16 and maxHeight 563 / 16. You can think like a grid divided in parts of 16 pixels.
