Я хочу, чтобы функция ball.move(); в приведенном ниже коде продолжала работать после однократного нажатия пробела. Это работает, только если я продолжаю нажимать клавишу пробела.
void draw() {
if (start == true) {ball.move();}
}
void keyPressed() {
if (key == ' '){start = true;}
}
void keyReleased() {
if (key == ' ') {start = false;}
}
Это игра для понга, которую я делаю, и каждый раз, когда мяч ударяется о край, он телепортируется в центр холста. Вот когда я хочу снова начать движение мяча вручную.
Вот весь код:

player2 = new Player(width-15, height/2, 30, 150);
ball.speedX = 10;
}
void draw() {
background(0);
textSize(40);
textAlign(CENTER);
font = loadFont("Arial-Black-48.vlw");
textFont(font);
ball.display();
if (start == true) {ball.move();}

player2.run();
//Score
