Where do I have to create road package ?

Question about the task

Racer (Part 10/28)

Games, Level 0, Lesson 5

Under discussion

Hi, I tried creating subfolder road in every folder and can't verify it. Help needed

The car's behavior currently doesn't match what we would expect:

- the car doesn't stop moving to the side when an arrow key is released; - the car drives right off the edge of the road and the playing field.

To fix this, you need to implement the correct behavior for the car when the RIGHT and LEFT keys are released.

Override the onKeyReleased(Key) method and there set the car's direction to Direction.NONE when this is necessary.

Create a RoadManager class in the road package in order to manage the flow of items on the road. Give it fields that will store the x coordinates of the edges of the driving surface.
Use them in the PlayerCar class's move() method to prevent the car from leaving the road.
If you check the road boundary before changing the x coordinate of the player's car, it will be able to put one wheel on the shoulder. But if you change х first and then check the boundary, the player's car will be strictly limited to the race track.
The choice is yours.

Requirements:

In the RacerGame class, the onKeyReleased(Key) method of the Game parent class must be overridden.
The onKeyReleased(Key) method must set the player's direction to Direction.NONE if the method's parameter is equal to Key.RIGHT and the player's direction is equal to Direction.RIGHT.
The onKeyReleased(Key) method must set the player's direction to Direction.NONE if the method's parameter is equal to Key.LEFT and the player's direction is equal to Direction.LEFT.
There must be a public RoadManager class in a separate file in the road package.
The RoadManager class must have a public static final int LEFT_BORDER field, initialized to RacerGame.ROADSIDE_WIDTH when it is declared.
The RoadManager class must have a public static final int RIGHT_BORDER field, initialized to RacerGame.WIDTH - LEFT_BORDER when it is declared.
The PlayerCar class's move() method must set the x field to RoadManager.LEFT_BORDER if x < RoadManager.LEFT_BORDER.
The PlayerCar class's move() method must set the x field to RoadManager.RIGHT_BORDER - width if x > RoadManager.RIGHT_BORDER - width.

package com.codegym.games.racer; public class ShapeMatrix { public static final int[][] PLAYER = new int[][]{ {0, 0, 123, 123, 0, 0}, {1, 0, 123, 123, 0, 1}, {1, 1, 123, 123, 1, 1}, {1, 0, 123, 123, 0, 1}, {0, 0, 123, 123, 0, 0}, {1, 0, 123, 123, 0, 1}, {1, 1, 123, 123, 1, 1}, {1, 0, 123, 123, 0, 1} }; public static final int[][] ROAD_MARKING = new int[][]{ {2}, {2}, {2}, {2}, }; }

This was my first try. I get this compilator output: com/codegym/games/racer/PlayerCar.java:30: error: cannot find symbol if(this.x < RoadManager.LEFT_BORDER) ^ symbol: variable RoadManager location: class com.codegym.games.racer.PlayerCar com/codegym/games/racer/road/RoadManager.java:6: error: cannot find symbol public static final int LEFT_BORDER = RacerGame.ROADSIDE_WIDTH; ^
