рони,
|
Но теперь просто выводится постоянный алерт и игра не останавливается и не начинается заново
|
Георгий777,
строка 126 добавлена |
теперь он вроде начинает заново, но размер змеи - 3, а не один, как должен быть с начала
|
Георгий777,
нужно написать свой resetGame который сотрёт snake |
if(game_over == true) {
alert("game over"); game_over = false score = 3; // return; snake = []; } но так не помогает( |
