Dibujar un camino en AndEngine para mover una imagen o el sprite

Question

hola soy nueva en el desarrollo de juegos Android yo uso AndEngine necesito ploat un camino, pero hay un problema

vistazo a la trayectoria image.The que necesito es como el primero, el objeto debería moverse desde la parte inferior hasta la mitad de la pantalla. Pero mientras trazado mi camino, se mueve al centro de la pantalla, pero vuelve al segundo punto como en la segunda imagen. La imagen se mueve a través el camino, pero es como la segunda imagen. Lo necesito como el primero. Debe detenerse en el 3er punto y debe comenzar desde el primer punto nuevamente.

Mi código es la siguiente

package com.example.sss;

por favor ayuda me.Thanks por adelantado

Answer 1

Si tiene tres puntos que debe indicarlo en el constructor de Ruta:

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

lugar

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