I am currently working on a school project for my own benefit. I have designed a Flappy Bird Game, I am now attempting to include a highscore board. I have attempted to use the imported ScoreBoard from greenfoot classes, however with the newest version of greenfoot. This imported Scoreboard no longer works due to an update in greenfoot adjusting the font and color changes. I was wondering if there is a way to fix the imported scoreboard, or if there is a simpler way to implement a highscore board. Thank you.

When starting a greenfoot project with said errors, greenfoot should offer you to replace old methods automatically (that's what happened with my old school project) actually.. Else u can just look up the current methods used by greenfoot and choose your own colors or just use an older greenfoot version (3.0.4 and below) https://www.greenfoot.org/doc/font_color

The first step in making the class compatible with the new version of greenfoot is removing the Color and Font import lines (or any java.awt import lines). Any other problems will then be highlighted and should be easy enough to fix. Keep in mind that NO color parameters can be 'null' and must be replaced with a true Color value.

Upon removing the 'java.awt.Color' import line it has highlighted only one error in my code, 
private void drawString(String text, int x, int y, Color color, int height)
    {
        getImage().drawImage(new GreenfootImage(text, height, color, new Color (0, true)), x, y);
    }
I have looked into this error and have so far I have not been able to think of anyway to fix it nor found anything that will help, if you can think of anyway to fix the error it will be much appreciated. Thank you

I have removed the 'java.awt.Color' import and upon doing this it has highlighted only one error in my code. however greenfoot has not offered to replace the old methods and I am unsure how I am able to access this option. The message that is being displayed in the current error is: "no suitable constructor found for Color (int,boolean) constructor greenfoot.Color.Color(java.awt.Color) is not applicable (actual and formal argument lists differ in length)" If you could explain how the option given by greenfoot to replace the old methods it would be much appreciated. Thank you.

Hey, The color constructor looks as follows 
Color(int r, int g, int b)
Creates a RGB color with the specified red, green, blue values in the range (0 - 255).
Alpha can be added after b, also as an int if required. https://www.rapidtables.com/web/color/RGB_Color.html

Instead of 'new Color(0, true)', you can use 'new Color(0,0,0,0)' to create a transparent color.

Thank You! I will give it a go.

I have been attempting for to implement changes to the code, adding the color constructor and so on. Yet I am still unable to fix the issues/work around them. I am not awfully experienced so perhaps this is the issue at hand and I simply can not see a simple issue, but any help would be very much appreciated

I have gone back to the final point I feel I was closest to having it working in my opinion. I will show what I currently have, I feel it is as close if not closer to working to when i attempted to implement the color constructor.

As always: What is happening? How is it different to what should happen? Do you receive any error message? I am not at home right now, so I don't have access to Greenfoot and can't see the differences between your code and the scoreboard class that you import. Why do you use 0x60 (and other hex numbers) there instead of simple ints?

I have pretty much gone back to the imported one, The error message being displayed is this "no suitable constructor found for Color (int boolean) constructor greenfoot.Color.Color(java.awt.Color ) is not applicable (actual and formal argument lists differ in length ) "

Change the hexadecimal values (values beginning with '0x') to decimal values. With each, remove the '0x', then take the last digit and add to it 16 times the second to last digit. The alpha digits start with A being 10, going up to F being 15.
