Zeichnen Sie einen Pfad in AndEngine ein Bild oder Sprit

Question

hallo ist neu in Android-Spiele-Entwicklung zu bewegen i AndEngine i einen Pfad ploat muß verwenden, aber es gibt ein Problem

Blick auf dem Bildes.Verfahren Weg ich brauche, ist Wie beim ersten sollte sich das Objekt vom unteren Rand bis zur Mitte des Bildschirms bewegen. Aber während ich meinen Pfad zeichne, bewegt er sich in die Mitte des Bildschirms, geht aber zum zweiten Punkt zurück wie im zweiten Bild. Das Bild bewegt sich durch der Weg ist aber wie das 2. Bild.Ich brauche es als erstes.Er sollte im 3. Punkt stehen bleiben und erst wieder am ersten Punkt beginnen.

ist mein Code unten

gegeben

Answer 1

Wenn Sie drei Punkte haben Sie es in Ihrem Pfad Konstruktor angeben sollten:

final Path path = new Path(3).to(CAMERA_WIDTH - 58, 10).to(10, 10).to(10, CAMERA_HEIGHT/2f); 

statt

final Path path = new Path(5).to(CAMERA_WIDTH - 58, 10).to(10, 10).to(10, CAMERA_HEIGHT/2f);
