I just want to share my "write text" snippet. I hope this snippet can ease you to display texts somewhere. I'm still very new to Greenfoot (javascripting specifically) btw, but I'm used to be active at other coding site and used to write snippets. So let's see if this is acceptable here.
How to use:
I'm sorry for my poor attempt :(
This is how it looks like (yeah, I'm working on a tower defense game):
Open here
import greenfoot.*; // (World, Actor, GreenfootImage, and Greenfoot)
import java.awt.Color;
import java.awt.Font;
/* ~ Display Text v1.3 ~

* Last updates:
* - Added lifespan and fade out functionality
* - Added update text and color feature
