This video is mostly for those who want to get a first impression of Greenfoot. We write a simple game in seven minutes (realtime; no cuts!), using Stride. For those who already know Greenfoot with Java: You will see that writing in Stride is not very different to writing in Java. For those new to Greenfoot: This is a quick introduction to Greenfoot and Stride at the same time.
As always, Greenfoot is available for free download.
Stride is very cool! I taught a Greenfoot class at our local middle school, and syntax errors are definitely a pitfall. Great solution to get kids started without having to worry about them.
