andengine aplicar fuerza

Question

¿Alguien sabe por qué aplicaforce solo funciona en uno de mis sprites? También cuando presiono los otros sprites también aplica fuerza al único sprite individual. El método nextTile funciona bien. com.martynnorman.jude

Answer 1

Se debe a que sólo tiene un Body -Variable, y se sobreescribe por el bucle. Cuando se han creado todos los sprites, solo se conoce el cuerpo del último sprite.

Debe aplicar la fuerza al cuerpo asociada con el sprite se hace clic.
