GameObject nach Norden drehen

Question

Ich möchte meine Karte nach Norden drehen, aber sie dreht sich weiter und hält nicht nach Norden. Ich möchte eine Ausgabe wie Google Map, wo die Rotation der Karte nach Norden festgelegt ist. Bitte überprüfen Sie meine Update() Methode. Schaut euch das Video hier: https://www.youtube.com/watch?v=liXmxdI3Adg&feature=youtu.be

Answer 1

Sie drehen sich unendlich statt Drehung der Einstellung.

Sie können etwas tun:

void Update() 
{ 
    var targetEuler = new Vector3(0,0,Input.compass.trueHeading); 
    img.transform.rotation = Quaternion.Lerp(image.transform.rotation, targetEuler, Time.deltaTime); 
}
