Today the agenda for the class was:
1. Check to see if the Squeak plug-in works in our browser.
2. Have students show-and-tell various projects they worked on in the past week.
3. Answer any questions about these projects.
The first project we saw was a one-person Pong game. We learned that you can use mouse coordinates in Squeak. This way we could control the moving wall with the mouse, rather than a joystick.
The second project we saw was a gyrating blob chasing a dude in a Ozzy shirt. For some reason the blob wasn't chasing the guy as expected but we didn't come up with a solution yet.
The third project was a Frogger game. There was a problem with the cars drifting upward ever so slightly as they moved horizontally. We found that the heading number shows up as integers by default. 90 degrees may actually be 89.78888 degrees. You can change the number of decimal points by clicking "decimal points" in the object's menu for heading.
The fourth project was a race track. One problem was we couldn't see one of the hidden objects. By going to World menu -> playfield options -> show all players, you can see the hidden objects.
You can have keystroke commands in Squeak but need to download a patch. The following website discusses how/where to install the fix for this:

Random notes:
Prof. Pitt has begun to populate the website with many "how-to"s, about Squeak. However, this information is badly in need of additional organization. Further, many of the items need elaboration. Prof. PItt requested (actually, he didn't, but he has edited these notes to say that he did) that people look over the entire how-to section, and help in various ways. Read the Goals on the how-to page.
We can upload our projects onto the Swiki but we should make sure we don't upload too much our we may run out of space.
