progress bar to follow actor
I'm not sure what you mean by "multipull actors", but here's an idea on how to follow an actor.
I may well have mis-interpreted what you're asking, but its worth a shot.
public class ProgressBar {
Actor following;
//Other fields
public ProgressBar(Actor following) {
this.following = following;
//Rest of constructor
}
public void act() {
followActor();
//Rest of act()
}
private void followActor() {
if(following != null
&& following.getWorld() != null) {
int x = following.getX(),
y = following.getY() - following.getImage().getHeight()/2 - getImage().getHeight()/2;
setLocation(x, y);
}
}
//Other methods
}
What do you mean by 'multipull' and in exactly what why do you want the progress bar to follow the actor?
