Try replacing (rearranging) lines 45 thru 52 with the following:
if (invuTimer < 150)
{
    if (getX() < 150) setLocation(getX(), getY()+2);
    invuTimer++;
    return;
}

when I use the code the boss stays at the top of the screen and gives me this error, if I keep the code the boss gets in his place and the same error shows up. Idk why but now its instantly shows the error without the pausing, maybe its cus i left the programm open too long. java.lang.NullPointerException at Sakuya.act(Sakuya.java:140) (thats the code) counter.setValue(counter.getValue() - 1); at greenfoot.core.Simulation.actActor(Simulation.java:567) at greenfoot.core.Simulation.runOneLoop(Simulation.java:530) at greenfoot.core.Simulation.runContent(Simulation.java:193) at greenfoot.core.Simulation.run(Simulation.java:183)
