Abstract
While the introduction of object-oriented programming slowly moves down the age groups - starting from advanced university courses, to introductory courses, and now into high schools - many attempts are being made to make object-oriented programming introduction less abstract and theoretical. Visualisation and interaction techniques are being applied in an attempt to give students engaging and concrete experiences with objects. Recently, the greenfoot environment has been proposed as another step in this development. In this paper, we describe new functionality in the greenfoot environment, especially the addition of user interaction programming via direct state manipulation. Direct state manipulation provides very low overhead graphical I/O handling at a level that makes it feasible to guide students to simple graphical game programming within a few weeks, while concentrating on fundamental object-oriented concepts in the structure of the program.
