Hey Community! I'm working on an RPG game atm, and i want the actor to move to the mouse clicked position. Sometimes it works fine, but sometimes he stops before reaching the target or he can't move after reaching the target. This is my code so far, hope you could help me. cya DMKxD 
private void Steuerung()
    {   
        if (status == STATUS_NORMAL) 
        {  
            if (Greenfoot.mouseClicked(null))   
            {
                zielX = 0;
                zielY = 0;
                NeuesZiel();
                status = STATUS_BEWGUNG;  
            }    
        }    
        else if (status == STATUS_BEWGUNG) 
        {
            Bewegung();
        }
        if(Greenfoot.mouseClicked(Bots.class))
        {
            angreifen = true;
        }
        else
        {
            angreifen = false;
        }
    }

    public void NeuesZiel()  
    {  
        MouseInfo mouse = Greenfoot.getMouseInfo();  
        zielX = mouse.getX();  
        zielY = mouse.getY();  
    } 

    public void Bewegung()  
    {
        if (zielY != getY() && zielX != getY())
        {
            setRotation((int)(180*Math.atan2(zielY-getY(),zielX-getX())/Math.PI));
            move(3);
        }
        else
        {
            status = STATUS_NORMAL;
        }
    }

From the code, I would say that the actor stops when either it is at the right horizontal of the target or the right vertical of the target. On line 36 replace '&&' with '||'. Test it, and report back.

Another issue may be that you are moving 3 steps at a time, so your actor could end up jumping back and forth over the target and never actually get there. Try this for your 'Bewegung' method: 
public void Bewegung()
{
    if (zielX != getX() || zielY != getY())
    {
        if (Math.abs(zielX - getX()) < 3 && Math.abs(zielY - getY()) < 3)
        {
            setLocation(zielX, zielY);
        }
        else
        {
            setRotation((int) (180*Math.atan2(zielY - getY(), zielX - getX()) / Math.PI));
            move(3);
        }
        if (zielX == getX() && zielY == getY()) status = STATUS_NORMAL;
    }
}
