You might want to post the code of the make text method, so we can see what you are asking about. Or at least, point us to the scenario you have seen it in.
Actually it's the balloons scenario that comes with the greenfoot download, in the scenarios folder. Sorry for being unclear.
Are you refering to the makeImage(String title, String prefix, int score) method in the ScoreBoard class?
That method is for the final 'Game Over' scoreboard. You might want to post what code you have for it, as well as what you use to call the method and from where. Also, explain exactly what is happening (absolutely nothing, an error message ). For best response, it is well to be complete and specific. Also, include what import statements you are using in the class.
Heres a method of doing it:
Also, in img.drawString("Text", x, y) x and y are not the positions you might expect:
- x is the x position of the first letter.
- y is the y position of the bottom of the first letter.
Oh and here's the link for the java.awt.Color documentation - look through the fields for a list of default colors you can use. If the color you want to make isn't one of those, then replace "Color.BLACK" with "new Color(int red, int green, int blue, int alpha)" where all of the parameters are in the range 0 <= parameter <= 255
There are other constructors for Color but that's the one I find the most useful. Oh and alpha is the transparency.
//You'll need this import statement:
import java.awt.*;
//And then here's the code:
GreenfootImage img = new GreenfootImage(500, 50);
img.setColor(Color.BLACK); //Change this to the colour of text that you want
float fontSize = 35.0f; //Change this to the font size that you want
Font font = img.getFont().deriveFont(fontSize); //This adjusts the default font to the correct size.
img.setFont(font);
img.drawString("The text that you want", x, y);
setImage(img);
This gave me the inspiration for this scenario :)
I did the code you told me, and although it compiles when I run nothing happens. I have put the method in a actor class, is this okay?
Hi toyttttt, if you go and download my FileDialog demo. You should be able to easily see how I'm creating the button; which uses the drawString command.

Yes, because there is not an object reference preceding 'setImage(..)', it would have to be in the class that you are setting the image for. I say again, for better assistance, please post the code in question. You will find solutions much quicker that way.
@toytttttt, Yes, sp33dy's method for creating the button would be a fine template for your needs.
@sp33dy, I revised your method to
setImage(new GreenfootImage(" Click here for dialog ", 30, Color.BLACK, Color.RED));
