Ich beginne gerade im Sprite-Kit und habe eine Straßensperre getroffen. Ich versuche, die alten Atari-Spiel-Asteroiden nachzustellen. Ich versuche gerade herauszufinden, wie man den Knoten "Schiff" von einer Seite des Bildschirms bewegt und die gegenüberliegende Seite herauskommt. Ein Beispiel hierfür wäre Pacman, der von der rechten Seite des Bildschirms auf die linke Seite des Bildschirms geht. Hilfe wird sehr geschätzt. Vielen Dank im Voraus, JaredWie mache ich einen Knoten von einer Seite des Bildschirms zum anderen gehen?

Was fragen Sie genau? Bitte fügen Sie weitere Details hinzu. – Laurel
