Folgendes Problem: Wenn ich jetzt z.B. die Linke Pfeiltaste drücke, geht das Feld wie gewünscht weiter. Allerdings bleibt die Figur nicht an ihrem Ursprungsort, sondern sie geht mit dem Hintergrund mit. Außerdem ist sie nur noch in Bruchstücken sichtbar. Zusätzlich zu diesem Problem lässt sich der Hintergrund auch nur einmal in jede Richtung verschieben. Ich vermute, dass das an der Funktion MoveWindow() liegt, aber ich weiß nicht, wie ich das Problen beheben kann. Ich hoffe ihr habt mich einigermaßen verstanden.
