You changed the value of the isGameOver boolean in a world to true, but that would not be in the running world. You changed it in another world that you created on the previous line.

It works now. I couldn't find the mistake on my own, so thank you very much for sharing your insights!

Remove line 2. Also, the getColorAt method does not work on a World object (it works on a GreenfootImage object) and requires two int parameters, not one.

Please refer to my Value Display Tutorial scenario.

<Code Omitted> I just insert this code into the circular bar I'm remaining there is no way to do

thx :)

Not sure if this is causing your error, but try to change: <Code Omitted>to <Code Omitted> And similar everywhere.

just want to see how it is looking before i start the real coding. just want to codes well just once

The constructor and everything in it will execute when the world is created. If wou want the methods to be executed at a later point, you can add an “act” method to your world which is automatically executed once each act cycle. You can use a variable as a timer and call the methods after a set number of act cycles.

The “isTouching” method is protected, so you can’t access it from the World. You could “cheat” and create a public method which does the same thing. The alternative is to have the code in the object which both actors should touch. <Code Omitted>

How can it be, when it creates Server objects and it is coded to be in a World subclass? Yes -- AFTER calling serverPopulation.

Thanks for your help. let me try it
