When the pivot point is no longer valid (the snake no longer has any parts that cross the pivot) I'd remove it from the array.

#Greenfoot snake game code how to

If I was implementing it I'd use an array of pivot points that would tell the snake how to turn pieces of the snake as it traverses the board. As the snake moves you can just increment over the array and change the points to take into account the direction of movement and how far to move. The snake object could have an array (or better yet an ArrayList) that stores the coordinates of the blocks that make up a snake. It wouldn't be unreasonable to let the snake draw itself on the board* or at least store it's display information for the board to handle. If it detects a collision on between the snake and itself, the game would end. If it the game board detects a collision between the snake and food, it would move the food sprite to the next position and invoke Eat() on the snake object in play. Probably a better idea would be to move user input elsewhere and have the game board communicate state changes to the various sprites (snake, food, wall etc) including collision detection.

It looks like you're trying to put a lot of sprite interaction logic in your snake class. I'm getting the feeling your question is more general than simple array handling.

Got a new task in School to code the Snake Game from scratch and need to use a array to add a new Snake bodypart when the Snakehead eats food and at the beginning the Snake need to have 1 head and 2 bodyparts.and I have no idea how to do this.can someone out there help me on right direction.how to start? Here is my code so far: x = getRandomInt ( 0, 25 ) * grid apple. wrap snake position vertically on edge of screen slow game loop to 15 fps instead of 60 (60/15 = 4) get random whole numbers in a specific range keep track of all grids the snake body occupies moves one grid length every frame in either the x or y direction the canvas width & height, snake x & y, and the apple x & y, all need to be a multiples of the grid size in order for collision detection to work When you become a Patron, you get access to behind the scenes development logs, the ability to vote on which games I work on next, and early access to the next Basic HTML Game.

This series is meant to give a basic outline of the game but nothing more.

Important note: I will answer questions about the code but will not add more features or answer questions about adding more features. Improve it so it only spawns in empty grid locations

Currently the apple spawns in any random grid in the game, even if the snake is already on that spot.

Allow the game to be scaled down to a phone size.

Use context.fillText() to display the score to the screen

When the snake eats an apple, the score should increase by one.

This is a basic implementation of the snake game, but it's missing a few things intentionally and they're left as further exploration for the reader. Snake is a fun game to make as it doesn't require a lot of code (less than 100 lines with all comments removed).
