blackplayer.dispose(); redplayer.dispose(); greenplayer.dispose(); dropsound.dispose(); rainmusic.dispose(); batch.dispose(); } }above code, trying move screen in beginning of render method try switch screen need call later in render method giving me fatal signal 11 when run app , application stops , have realized problem being caused batch.dispose() in dispose().
if remove batch.dispose() code application runs happens both screen runs simultaneously i.e. current screen not go away , screen comes play, thereby both displaying own content.
any idea , how officially switch screen?
game application origin class.
dispose() of game should called when you're exiting game. doesn't matter on screen arerender() method of game called .
so try in way :
create screen(let's assume playscreen) gameover screen , put render method code in render method of screen , of required stuff of picasso class.
from create method of picasso set playscreen setscreen(new playscreen()) method of game class.
