Again I fail the test but it works in my game

Question about the task

Under discussion

I tried many different thing and it seems to work correctly in my game but I keep failing the test. Someone any idea why??

Let's add the ability to control our snake. To handle key presses, override the Game parent class's onKeyPress(Key) method. Depending on which key is pressed, set the appropriate direction of snake movement.

Bear in mind that a snake cannot instantly turn 180 degrees.

Requirements:

The SnakeGame class must override the Game parent class's onKeyPress(Key) method.
If Key.LEFT is passed to the onKeyPress(Key) method, you need to call the setDirection(Direction) method on the snake with Direction.LEFT as the argument.
If Key.RIGHT is passed to the onKeyPress(Key) method, you need to call the setDirection(Direction) method on the snake with Direction.RIGHT as the argument.
If Key.UP is passed to the onKeyPress(Key) method, you need to call the setDirection(Direction) method on the snake with Direction.UP as the argument.
If Key.DOWN is passed to the onKeyPress(Key) method, you need to call the setDirection(Direction) method on the snake with Direction.DOWN as the argument.
The Snake class's setDirection(Direction) method must not change the direction of snake movement if the method parameter is the opposite of the current direction.

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

u need to add this code in setDirection(Direction direction) method, credit @Inderdeep Singh

if( direction == Direction.LEFT && this.direction != Direction.RIGHT ){
           this.direction = direction;
       }
       else if(direction == Direction.RIGHT && this.direction != Direction.LEFT){
           this.direction = direction;
       }else if(direction == Direction.UP && this.direction != Direction.DOWN){
           this.direction = direction;
       }
       else if(direction == Direction.DOWN && this.direction != Direction.UP){
           this.direction = direction;

Can you explain the difference between direction and this.direction.

this.direction is the current state of the direction that is active (Direction.LEFT by default when you start the game as you initialized direction variable with that). direction would be the new direction that you are passing to it as a new value.(here through the method onKeyPress(Key)
