Python - problem med if sats.
Hej!
Efter några år utan dator och kodande lyckades jag komma igång igen här i jul. Problemet är en if-sats just nu iaf. Jag pillar på en pongklon, hela koden är längst ner och if-satsen är i fetstil. Jag har klippt ut själva if-satsen nedan. Jag använder mig av VS-Code och har lagt till pygame.
Det jag vill är att för alla bollar som finns på spelplanen försvinner tills det bara finns minst en kvar. Hamnar en boll bakom en spelare blir det poäng och extra bollar försvinner. Jag tycker jag har provat varianter med parenteser, AND OR, flera if-satser. Tills jag hittade nedan lösning, den fungerade så jag provade ändra värden då slutade den fungera. Ändrade tillbaka och då fungerade det inte längre. Möjligheterna till att jag snurrat till det är oändliga.
Senast jag pillade var längesedan, enligt github 5 år sedan.
balls: Håller informationen om alla bollar. När spelaren trycker på högerknappen läggs en boll till i list balls.
ball.rect[0]: innehåller X positionen för bollen.
for ball in balls:
if 20 > ball.rect[0] < 750 and len(balls) > 1:
#if ball.rect[0] <= 20 and len(balls) > 1:
print(ball)
balls.remove(ball)
ball.draw()
ball.move(players)
