How do I create a loop in Processing that switches between three or more scenarios (summer, winter and fall) when my object (car) reaches the edge of the window?

A way of doing, not very beautiful but that works:

In variable declarations include:

int season = 0; // 0=summer, 1=fall, 2=winter

Create this new method:

void changeSeason() {
    // Gira o índice da estação atual
    if(++season > 2) season = 0;

    // Desenha o cenário correspondente
    if(season === 0) {
        scenarioSummer();
    } else if(season === 1) {
        scenarioFall();
    } else if(season === 2) {
        scenarioWinter();
    }
}

And the draw method would look like this:

void draw() {
    timeFrame = frameCount % width;

    // Se chegou no fim da tela
    if(timeFrame === 0) {
        changeSeason(); 
    }
}
