java - Moving Actor using TouchDown event in Scene2d -

i'm looking way move actor when touched. i've tried code below. however, related actor lacks back upwards touchdown event, i'm getting nullpointerexception.

actor.addlistener(new inputlistener() { public boolean touchdown (inputevent event, float x, float y, int pointer, int button) { event.getrelatedactor().addaction(moveby(0,10,0.5f)); homecoming true; } });

any suggestions?

you want utilize gettarget() actor event originated from.

the getrelatedactor() method events involve 2 actors (like focus alter or enter/exit events). isn't particularly clear in doc, if @ focusevent doc getrelatedactor you'll see how used there.
