Делаю урок 8

здесь ошибка float speed = 0;
int dir = 0; использование инициализатора элемента данных не допускается

надо мне поправить форум, откуда то “quot;” берется в твоем коде при вставке сюда =\
Теперь по твоей проблеме – скорее всего ошибка в том, что твой компилятор по старее моего и в нем еще не была реализована такая вещь как инициализация переменной в классе. Поэтому инициализируй переменные в конструкторе класса. То есть оставь как есть
float speed;
int dir;

А в конструкторе уже пиши Player(String F, int X, int Y, float W, float H){
dir = 0; speed = 0;

Тему перенес, в другой раздел
