0000 - Intro to C on Windows

0001 - Setting up the Windows Build

Setting the environment - 19:45

• install the C/C++ tools for Windows
• setup the cl, by loading vcvarsall.bat x64

0002 - Opening a Win32 Window

0003 - Allocating a Backbuffer

Different meanings of static - 17:00

Context dependent:

add to a function

makes it invisible outside the file

add to a variable in a function

persisting a value, between scope recreation

add to variable outside a function

global variables

Good practice to give semantic meaning:

1. #define internal static
2. #define local_persist static
3. #define global_variable static

0004 - Animating the Backbuffer

Pixels in Little Endian Memory - 1:19:49

Code (theory)	RR GG BB xx
Memory (little endian)	xx BB GG RR
Memory (Microsoft's preference)	xx RR GG BB
Code (actual)	BB GG RR xx

0005 - Windows Graphics Review

0006 - Gamepad and Keyboard Input

Dynamically Loading Libraries - 31:50

• prevents the game from crashing if user doesn't have XInput installed
• essentially we load the library in a similar fashion as Windows, but during execution of the program
• use a dummy function with macros

Load the xinput1_4.dll via LoadLibrary and retrieve the address to the function we want to use from that library by calling GetProcAddress. (essentially this is exactly what Windows anyways).

Keyboard Input - 46:55

0007 - Initializing Sound

Why are there two buffers to initialize the audio in Windows? - 1:27:56

The Windows code is complex due to legacy, while the SDL version felt reasonable. A lot of the annoyances doesn't apply here.

I'm interested in understanding how game engines and games work from scratch.
