I got it, it just the problem within filename, so I just need to rename the filename, actually it was basic mistakes xD u don't have to write your own file extension because greenfoot can read it automatically, i.e I changed my filename from "highscore.txt" to just "highscore" and save it to the folder that you pointed, thanks it helps! have a nice day

Try a number like 0.8 for gravity and remove lines 56 thru 58 in the Hero class.

woooah, I can do that? How exactly would I word that to make the actor look for that color?

Line 4 is not where the spacebar is only down. Its state is not determined until after line 5. An else clause following the if block (lines 5 thru 8) would be used for key down state. Line 4 is only for a unknown change in the state of the spacebar.

In the DUP class code, add the following line after line 18: <Code Omitted>Then, in the act method, add the following line after line 34: <Code Omitted>These lines will immediately cause an exit from the methods so that no further code that require the actor be in the world be executed.

Add a counter field to count number spawned: <Code Omitted>Add the following line immediately after spawning: <Code Omitted>Adjust the limit (10) as needed.

You could keep a reference to the Runner object in your World subclass along with a "getter" method: <Code Omitted>Then, use the following in your Actor subclass:
