could somebody please explain the issue?

Question about the task

Resolved

validation fails with the following error message: The createGame() method must assign the created Snake object to the snake field. Isn't that what line 21 (snake.draw(this);) is supposed to accomplish?

Once we have a snake, we need to draw it. To do this, by analogy with the Apple class, create HEAD_SIGN and BODY_SIGN constants in the Snake class. They will store symbols for drawing the head and body of the snake. Also, create a draw(Game) method to draw the snake on the playing field.

We'll handle drawing the snake from the SnakeGame class. So, create a Snake snake variable in the SnakeGame class: it will store the snake's current state.

In the createGame() method, create a new snake in the center of the playing field and assign it to the snake variable. In the drawScene method(), call the draw(Game) method on the snake to draw it on the playing field.

Requirements:

The Snake class must have a private static final String HEAD_SIGN field that is initialized when it is declared. For example, you can use this UTF-16 symbol: "\uD83D\uDC7E".
The Snake class must have a private static final String BODY_SIGN field that is initialized when it is declared. For example, you can use this UTF-8 symbol: "\u26AB".
The Snake class must have a public void draw(Game) method.
The draw(Game) method must call the Game class's setCellValue(int, int, String) method on each GameObject in the snakeParts list.
The setCellValue(int, int, String) method must be called with arguments (x, y, HEAD_SIGN) on the snake's head (the element with index 0 in the snakeParts list).
The setCellValue(int, int, String) method must be called with arguments (x, y, BODY_SIGN) on each segment of the snake's body (elements with non-zero indices in the snakeParts list).
The SnakeGame class must have a private Snake snake field.
The SnakeGame class's createGame() method must create a new snake (instance of the Snake class) with coordinates (WIDTH / 2, HEIGHT / 2) before calling the drawScene() method.
The createGame() method must assign the created Snake object to the snake field.
In the drawScene() method, the snake object's draw(Game) method must be called last. Pass this to the method.
The Snake class must have a statement that imports the entire contents of the com.codegym.engine.cell package.

package com.codegym.games.snake; import com.codegym.engine.cell.*; public class Apple extends GameObject { private static final String APPLE_SIGN = "\uD83C\uDF4E"; public Apple(int x, int y) { super(x, y); } public void draw(Game game) { game.setCellValueEx(x,y,Color.NONE,APPLE_SIGN,Color.LAVENDERBLUSH,75); } }

Line 9 you have the class's snake variable. This variable needs to be initialized in the createGame() method. Right now the above code does not do this.

I would give the snake object another name like snake2 and then private void createGame() { Snake snake 2 = new Snake(WIDTH/2, HEIGHT/2); this.snake = snake2; snake.draw(this); drawScene(); }
