Некоторые фоне Я разрабатываю игру в Java, я использую Netbeans, чтобы построить его я в настоящее время есть 3 Java файлыLinking MouseEvents из одного Java-файла в другой файл Java
- App.java
- Совет. Java
- Piece.java
в настоящее время Когда она работает она показывает пользователю простую шахматную доску со всеми частями в правильных положениях и т.д.
Это все сделано в Board.java
Моя проблема в том, что движение для кусков сделано в Piece.java, в настоящее время у меня есть белая пешка и мыши, которые управляют ею, но когда я запускаю программу на плату появляется вместе с кусками, но ни одна из фигур не перемещает даже белую пешку
и я в тупик, как, почему я думаю, что, возможно, я не связал их, вероятно, с доской или что-то в этом роде или, может быть, есть что-то u с моими мышьяками
Также у меня нет ошибок в моем коде при его запуске
Вот ява файлы

So a Pawn is able to move two squares forward one its first go but only one square after that.
The Pawn is the only piece that cannot move backwards in chess...so be careful when committing
a pawn forward. A Pawn is able to take any of the opponent’s pieces but they have to be one
square forward and one square over, i.e. in a diagonal direction from the Pawns original position.
If a Pawn makes it to the top of the other side, the Pawn can turn into any other piece, for
demonstration purposes the Pawn here turns into a Queen.
