Please provide example blocks, or an aia project, to show how the less obvious properties are set, and with what values.

Ready, I have uploaded the aia project. @TIMAI2

It does not have any library, it does not need a web view, just an Arrangement, the game is offline, it is pure java code.

did you write that java code yourself or did you find that code somewhere in the internet? In case of the latter please provide a link to the source and credit its author

No libraries, no other people involved.

I think that everything can be done without libraries, although it's more difficult, but not impossible.

It's difficult for me but I like it.

Nesse jogo da cobrinha, o fim da partida ocorre corretamente quando a cobra toca na borda superior ou inferior.

Problema:
Quando a cobra encosta na borda direita ou esquerda, o jogo nĂŁo termina. Em vez disso, ela atravessa a tela e reaparece do lado oposto:
Se estiver indo para a direita, ao atingir a borda, reaparece na esquerda e desce uma linha, continuando o movimento para a direita. Esse ciclo se repete até que chegue à borda inferior e o jogo acabe.
Se estiver indo para a esquerda, o processo é semelhante, mas a cada retorno ela sobe uma linha, até alcançar a borda superior e terminar a partida.
Esse comportamento torna o movimento da cobra previsível e pode ser explorado pelos jogadores. Por exemplo: se a comida estiver posicionada na parte inferior, basta deixar a cobra bater na borda direita para que ela siga sozinha, linha por linha, até alcançar a comida, sem esforço do jogador.

A ideia parece ter sido implementada como uma forma de evitar que, caso o jogador pare de jogar, a cobra fique indefinidamente presa nas laterais. Assim, o jogo garante que ela acabe eventualmente ao tocar a borda superior ou inferior.
Porém, essa mecânica abre brechas para atalhos e estratégias fáceis, o que reduz o desafio e compromete a dificuldade original do jogo da cobrinha.

Please add Left, Right and Up, Down buttons for controlling Snake because it is not easy to play by touching the screen

Thanks You Very Much Sir

Tested the new Snake Game (v1.1) works perfectly!
The speed, color, and collision updates are all fixed and smooth.
If your old version gives errors, just remove it first before adding this one.

:snake: Great job, everything’s running fine now!

Please Check Speed Block Not Work Propper . I Want Slow Speed=10 But Not Work .

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Thank you.

If you put smaller numbers, you will get more speed, if you want the snake to go slower you must put a larger number.

:snake: Snake Game Extension — Feature Request / Update Suggestion

Hi @Joejsanz,

First of all, thank you so much for creating this amazing Snake Game Customizable extension :raised_hands:.
I’ve tested it in my project and it’s working great. But I have a few feature improvement suggestions that can make this extension even more powerful and flexible:

:compass: 1. Boundary Wrap Feature (Like Old Nokia Snake Game)
Currently, when the snake touches any boundary, the game ends.
:point_right: I want to suggest an option where:

  • If the snake touches the left boundary, it should reappear from the right side.
  • If it touches the top boundary, it should come from the bottom side (and vice versa).
    :white_check_mark: This will make the gameplay more fun and classic, just like Nokia’s old snake game.

:turtle: 2. Speed Control Fix
Right now, even when the speed is set to 0, the snake moves too fast.
:point_right: Please make the speed truly adjustable from very slow (0) to fast — gradually increasing.
This will allow better difficulty control in the game.

:brain: 3. Custom Game Over Conditions
Currently, Game Over happens automatically on boundary touch.
:point_right: Instead of forcing game over on first boundary touch, please give developers control to:

  • Decide after how many boundary touches (e.g., 3 or 4 times) the game should end.
  • Or even manually trigger Game Over from blocks if needed.
  • Snake should also be able to self-collide with its body to trigger Game Over.

:toolbox: 4. Optional Game Over Behavior
There can be a block like:
SetGameOverBehavior ( "Boundary" / "Manual" / "Wrap" )
or
SetMaxBoundaryTouches ( number )

  1. Please Add Padding or Margin options in Game Layout Because When Food code in boundary corner then 95% time Game Over.

This will make the extension much more flexible for game developers.

These changes will make the Snake Game extension feel much more like a real classic snake game and give full control to the developer.
Thank you again for your hard work :pray:.

Best Regards,
[@Kabir_Khan]

These are good ideas that could be added, thank you for the suggestions.

  • The speed is set by time in milliseconds, the less quantity you put the faster it will go, if you want it to go slower, you must put more time, more quantity of number, for example if you put 1000, that is 1 second, every second the snake would move.
