Question about the task

Snake (Part 11/20)

Games, Level 0, Lesson 1

Resolved

The code I've added for this task is: Snake Class - line 39 SnakeGame Class - lines 38-44

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.Color; 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.RED, 75); } }

I got rid of the getDirection() method in the Snake Class and instead changed the setDirection() method to:

public void setDirection(Direction direction){
      if (this.direction.equals(Direction.UP) && direction.equals(Direction.DOWN)) return;
      if (this.direction.equals(Direction.DOWN) && direction.equals(Direction.UP)) return;
      if (this.direction.equals(Direction.LEFT) && direction.equals(Direction.RIGHT)) return;
      if (this.direction.equals(Direction.RIGHT) && direction.equals(Direction.LEFT)) return;
      this.direction = direction;
  }
