Ich habe mich gefragt, ob irgendjemand mich in die richtige Richtung lenken könnte. Ich habe ein Pong-Spiel entwickelt, das aufgrund von Flackern doppelt gepuffert werden muss. Ich habe versucht, einen Teil des Beitrags hier anzubringen, um ihn zum Laufen zu bringen, aber ich bin immer noch ein Anfänger mit dem Swing, der ausreicht. Jede Hilfe wäre unglaublich, danke.
