How to stop an actor while letting the other actors keep moving?

Hello friends, I'm trying to make an if statement that basically says if they are at the edge of the world they stop. Is there a simple command to make an actor stop and letting the other actors resume their scripts? I'm sure you can do this with a line of code but is there a command for this?

Do you want the actor to stop forever and just sit there? If so, just make a Boolean variable call it something like NeverMoveAgain, set it to false upon construction. When the edge of the world is detected set this variable to true. In the act have this 
Public void act()
{
    if (NeverMoveAgain)
        return;

... Rest of routine here ...
}

If you use a World constructor 'super' call with only three int arguments, 'super(int, int, int)', then your world is bounded and if your actors only move horizontally and vertically, they will stop automatically at the world edges. However, half of their images will be cut off by the edge of the window. You could use 'getImage().getWidth()' and divide it in half and then use an 'if' statement for each side edge -- 'if (getX() < halfWidth)' and 'if (getX() > getWorld().getWidth()-halfWidth)' for the horizontal edges. Then do similar for the vertical directions. That would keep the entire image of your actor in view, stopping it at the edges.

Pretty smart actually :) I'll try that when I get back on my program
