Игра понг мой мяч продолжает идти выше столкновений

Question

У меня есть простая игра в понг, где я могу забить мяч и проверить, нет ли столкновений на данный момент.У меня были столкновения с X и Y работающими, но так как я добавил углы к траектории шара, столкновения в координате X иногда терпят неудачу, не знаю почему.Так что это то, что у меня есть на данный момент, проверка коллизий выполняется функцией ballMovementHandler .

var ctx;

        player = new Player()
        ball = new Ball()
        attachKeyboardListeners()   
        reset();
        animate();  
    }
