Ich habe ein Spiel entwickelt, in dem farbige Punkte (SpriteKitShapeNodes) vom oberen Rand des Bildschirms nach unten fallen. Vorher habe ich die SpriteKit-Gravitation benutzt, um die Punkte fallen zu lassen, aber ich habe entschieden, dass ich den Fallaspekt verbessern wollte und beschloss stattdessen, Impulse zu verwenden. Aus irgendeinem seltsamen Grund empfangen die Punkte nicht die Impulse oder etwas anderes. Die Punkte bewegen sich überhaupt nicht. Punkte von Interesse sind in den "Ändern [Farbe]" Funktionen.Apply Impulse funktioniert nicht richtig

Sie sollten auf jeden Fall den Namenskonventionen folgen, besonders hier auf StackOverflow (wegen falscher Hervorhebung), wie @crashoverride777 in seiner Antwort gezeigt hat (und yeah, 0.1 hat wahrscheinlich keinen Effekt auf Ihren Körper). – Whirlwind
