Diary During Summer Vacation 10

As discussed with Tim 2 months ago, what I'm trying to do is to finish a running software prototype, that we can say is a 60-70% finished software. The software prototype should already provide all basic functionality to create and edit a knot. The prototype should be well documented as well, so that during the session all other members who are not that familiar with C# or XNA game engine can then do a little coding work according to the documentation. With this in mind, this week I'm continuingly working on the project. Since the integration of windows form and XNA is too time-consuming, I'm thinking of another solution to purely draw our own buttons using XNA framework. I looked into some sample codes and tutorials from XNA game developer's club, feeling confident to do so now.
