[2:19][Overview of the previous day's work]
[5:11][An introduction to functional programming]
[10:44][Methods for making our programs more functional]
[11:41][Rationale for moving keyboard handling out of Win32MainWindowCallback()]
[14:37][Finishing the keyboard processing code]
[15:55][Adding a fifth controller (the keyboard)]
[17:00][Adding 32-bit and 64-bit compiler options to the build.bat]
[19:54][Ensuring keyboard state persists across frames]
[22:35][An Assert() that we didn't do anything stupid]
[23:50][Finishing our directional stick code with deadzone processing, no zombies.]
[29:36][Using the deadzone values from MSDN]
[35:05][Iterating across all the controllers in GameUpdateAndRender()]
[36:23][Testing new input code]
[37:34][Changing game_controller_input to work across both keyboard and gamepad]
[41:12][Adapting the keyboard and gamepad code to the new structure]
[44:55][Connecting the stick input into a fake directional pad]
[48:16][Hooking up the real DPad]
[52:05][Adding an IsConnected member to game_controller_input]
[53:07][Buffer Overrun encourages some bounds checking]
[56:44][Why did we overrun the buffer?]
[59:26][Adding some last minute keyboard inputs]
[1:00:06][Final Thoughts]
[1:02:28][Q&A][:speech]
[1:02:50][Check the array in the Buttons union, you might want 12 now that you've added start and back]
[1:08:54][Is that some copypasta, or is it really supposed to be all MoveLefts?]
[1:11:24][Could it be good to apply some integration on the keys, so we don't just set the value to binary -1/1?]
[1:12:56][Can you talk about the deadzone being round vs rectangular at hardware USB, HID, and XInput API layers?]
[1:19:15][Maybe it's a round deadzone?]
[1:23:40][I'm 16 days behind, is there a better way to catch up than watching all the days on YouTube?]
[1:24:22][For the build.bat, you can build for Windows XP 64-bit using 5.2 instead of 5.1]
[1:24:33][On the inline method for GetController(), what happens if you pass in -1 for index?]
[1:25:50][Can you do struct buttons_type (name the structure) and still get the benefits..?]
[1:26:39][I don't get using Win32 prefix for function names when compiling for 64-bit.]
[1:27:34][I was thinking about processing game input in a separate thread so it is framerate independent, but I heard you could introduce input lag. Is that true?]
[1:28:46][You said a circular deadzone would be good for gameplay, why don't you just make it circular? The deadzone would just be a little bit bigger.]
[1:32:02][DirectInput vs XInput, which is better?]
[1:33:17][You deleted the Min/Max macro TODO...]
[1:34:03][So when you use the ZeroController, why not just go *NewKeyboardController = {}?]
[1:35:29][stddef should include offsetof(), you can use that to make your assert a little simpler.]
[1:37:56][Final Wrap-Up][:speech]
