Viewing the history.
With that commit, another feature of SVN can be introduced. Open the history
window again by going to SVN Show Log. Click on the most recent commit,
revision number three. In the third dialog window, you'll see the modified
/HelloWorld/HelloWorld/Program.cs file. Right-click on this and choose Show
Changes, as shown in Figure 4.17.
This will bring up a new program called TortoiseMerge. TortoiseMerge will
display two files at once: the current commit and the previous commit, as is
shown in Figure 4.18. In the previous commit, Hello World is crossed out and
highlighted in red; this means it's the area of code that's changed and the text has
been removed. In the current commit, we can see that it has changed to ''Let's
make some games.''
This merge tool is very useful for seeing how code has changed.
Tao
Tao allows C# to access OpenGL's functionality. It's very simple to install and
add to a game project. The installer is available from sourceforge ( http://source-
forge.net/projects/taoframework/) , and it is also included on the CD. As new
features are added to OpenGL, Tao is updated to include them.
