How can i use those classes (see in the topic) in my scenario

2018/2/5

You need to get the score which should be used, so the score variable in the world in which the actor is (or in your case just the class because most of your variables are static for no reason...). Right now, the score variable is private so you will need a getter method to access it.

From what I gave, you should have been able to figure out that it should actually be 'World_30.getScore()' in the Timer30 class (and similar in the other timer classes). Apparently you are not applying yourself at all and having others do the work for you.

I dont know why i cant get my self together. Maybe its the fact that i am not american, and cant get your things straight.

Yea ikr.At school we stopped on addobjects stuff and then i had to carry on by my self.I got more stuff to do than wasting my time here dan.Wouldnt that be a stupid idea? I came here all alone.I have been using greenfoot 2 months. Calm down.I am not using AI or i am programmed to do this automatically.I edited the

MainMenu.saveHighScore(1,World_30.getScore());

and added it to the timer30 class on the part

 if (cycles == 0)
        {
            Greenfoot.setWorld(new GameOverScreen());
            MainMenu.saveHighScore(1,World_30.getScore());      
            
            sound.play();
        }

I will be looking to this,and also find a solution to make the highscores go to a new class with a custom image next. See ya!

So you say that i somehow link them together? Make a variable on the mainmenu and one on the timer and just communicate? I also made my private voids to public

most of your variables are static for no reason.

I did not see any issues with what static fields were present. They are either global constants or used outside the scope of a single game (or there is only one used within any game).

Right now, the score variable is private so you will need a getter method to access it.

One is already present (as you may well have since found out).

Can just get where the hell to put this. MainMenu.saveHighScore(30,World_30.getScore()); . I got it that i must put it in the timer30 and etc classes.But,in the act?,a new void? Also i put the highscore on the gameover screen.class http://www.greenfoot.org/scenarios/20792 Thats what i changed

Thanks. But i get underlines on > MainMenu.saveHighScore(1, score); ! Also i will put those in the scoreboard at the end of the game,So i will change MainMenu to GameOverScreen. Correct?

That was also given above. Read through the discussion before asking and making me repeat myself.

You will have to be more specific as to what you are referring to -- and also show what class and what codes you are dealing with.

Where is your saveHighScore method now? It seems like it isn't in the MainMenu world anymore.
