alice-teacher Chapter 5 Zeus Exercise (in Dann, Cooper, Pausch) not working

[Don Slater]

The December version had a parameter passing bug. The bug has been fixed in our current version, but we are not quite ready to release the version yet. You can still download and try the experimental version as most of the previous features will still work. All additional feature like the Spanish translation or the update menu is still work-in-progress. Download at http://www.cs.purdue.edu/homes/aik_min/. Let me know if you find any other bugs.

Sorry,
Don Slater

For Chapter 5, the “Zeus” exercise worked through in the chapter, we’re getting a “target value must not be null” when running the code. We’re using when the mouse is clicked on anything event, and it seems that our “target” object parameter is not being recognized in our “prepareToShoot” method. Any clues or advice? This worked for me in the past with the older version of Alice and the same code, but not now.
