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

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.

Of course, since we didn't cover how to use the results of getObjects (or even mention the get() method), there must be another (much simpler) way to do this!

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:

sending variables between 2 files

By yaronbr, with no replies.

hello. im new to greenfoot, and im trying to create a board game where the board of the game is revealed to all players but each players hand can only be seen by that player. i created two different greenfoot projects and am trying to send a variable between them so one project can influence the other. tried doing this with an abstract java class but it doesnt seem to work a) is there a way to get two projects to communicate with each other? b) is there a better way of creating a game like this? thanks

Multiple worlds

How could i save all the states of my main world, create a different one, lets call a battleWorld, do some stuff in it, and then go back to the main world without resetting everything (saving the progress). For example i have the main world where the player walks around, if the player comes in contact with some particular object then it will initiate battle and once the battle ends the world will continue running where it left off. Not too sure how to implement this. I was told that a possibility could be to create the new "battleWorld" and have it point to the original world
