Minor updates this week

As well as the new world editor, there have been some other small updates to JAKE this week.

Firstly, the graphics have been improved slightly in the JAKE Java library, so that there's no longer the same stretching and pixelating as before. The wall and beeper icons are now crisper. You can see this in one of the screenshots for the world editor, when compared to a scenario from a few weeks ago:

Dynamic class diagrams in JAKE

It’s been noted [e.g. 1] that showing the static class structure is important in teaching materials and tools. BlueJ, for instance, places a lot of emphasis on this.
The JAKE IDE dynamically compiles a class diagram as classes are added to the JAKE program. Every program starts with a default class diagram that shows all the classes in the main JAKE package: World, Mover, Robot, and so on.
