Error says there are no arguments in the Snake constructor?

Question about the task

Snake (Part 6/20)

Games, Level 0, Lesson 1

Resolved

Getting the following error:

com/codegym/games/snake/part06/Snake.java:12: error: constructor GameObject in class com.codegym.games.snake.part06.GameObject cannot be applied to given types;
    public Snake(int x, int y){
                              ^
  required: int,int
  found: no arguments
  reason: actual and formal argument lists differ in length

could someone explain what this error means? I don't understand why I'd need to consider the parameters of the GameObject constructor if I am creating a new constructor. Plus, the parameters of the Snake constructor (int, int) are the same as the GameObject constructor (int, int), so I'm just not sure what I'm doing wrong

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 SnakeGame extends Game { public static final int WIDTH = 15; public static final int HEIGHT = 15; private Snake snake; @Override public void initialize() { setScreenSize(WIDTH, HEIGHT); createGame(); } private void createGame() { snake = new Snake(WIDTH/2, HEIGHT/2); drawScene(); } private void drawScene() { for (int x = 0; x < WIDTH; x++) { for (int y = 0; y < HEIGHT; y++) { setCellColor(x, y, Color.ORANGE); } } snake.draw(this); } }

In the draw method, you should call this on game.setCellValue, not GameObjcet
