Game Development Reference
Before proceeding, try to compile and run the application from this chapter's source
code ( F5 in Visual Studio). A new window should launch with either a plain-white
or garbled background (depending on various low-level Windows configuration set-
tings) as shown in the following screenshot. Do not worry if you see a garbled back-
ground for now as this will be resolved later.
It is also worth checking that the callback functions are working properly by adding
breakpoints to them and verifying that they trigger each frame, and/or when you
press a key or click on a mouse button.
