Drehen Sie das Bild um die Mitte mit Pygame [Duplikat] ⇐ Python

[Anonymous]

Ich mache ein Spiel in Pygame und versuche, ein Waffenbild um meinen Spieler um zu drehen, aber derzeit dreht sich das Bild um die obere linke Ecke des Bildes. Daher liegt die einzige korrekte Rotation bei θ = 90, -90 und ist bei θ = 0,180 falsch (umgedreht auf den Spieler anstelle von weg). Ich weiß nicht, wie ich diesen Fehler beheben kann. < /P>

I tried adjusting the angle by adding to it at certain degrees, but it just reversed the problem. I've asked ChatGPT to see if it could fix the issue, but it results in the same problem, unable to fix the issue. I tried using solutions from similar problems, but to no avail.
