Как сохранить спрайт от "прыжков" более одного раза в Phaser 3?

Question

Позвольте мне сказать, что для начала я уже задавал этот вопрос один раз. Ответ работал нормально, но с тех пор я добавлял код, и теперь предыдущий ответ не работает.

Ранее я решил эту проблему, добавив переменную с именем skaterTouchingGround и установив для нее значение true, когда фигурист "столкнулся" с землей (или когда он был на земле). Затем, когда я заставил игрока прыгать, после обнаружения клавиши прыжка, skaterTouchingGround будет установлен в false. По какой-то причине это больше не работает, поэтому я думаю, что мне нужен новый способ ограничить моего игрока одним прыжком, прежде чем он снова упадет на землю.

Я попытался изменить способ определения значения переменной и изменить способ определения нажатия клавиши.

Вот полный код игры

//Configurations for the physics engine
var physicsConfig = {
    default: 'matter',
    matter : {
        gravity: {
            x: 0,
            y: 2.5, // <--This is the only way I could get the skater to roll up the ramp.
        },
        debug: true //CHANGE THIS TO TRUE TO SEE LINES
    }   
}
