[0:07][Recap]
[0:53][Plan for today]
[2:32][Features and limitations of our current radial menu]
[4:01][We will build our UI around the debug features we already have]
[5:50][Let's find a way of turning debug features on and off easily from the debug interface]
[6:31][Quick review of the debug camera]
[7:20][There's a conflict between the reloading system and the debug event array collation]
[8:33][Maybe we should flush all events after a reload]
[10:12][Flushing the array event buffer]
[12:15][The DLL reloading already cleared that buffer. We only need to restart the collation process]
[14:00][Moving the ExecutableReloaded flag from the game input to the game memory]
[14:59][Testing it]
[15:39][The current way of switching between regular and debug cameras is inconvenient]
[16:37][We would prefer to automate the process of changing the code and recompiling it]
[18:02][We will collect all switches inside the globally accessible handmade_config.h]
[20:03][Be banana-cakes][quote 256]
[20:21][Assigning a type to config switches]
[20:56][Rewriting the config file from inside the game code]
[22:01][Implementing WriteHandmadeConfig]
[23:31][We resort again to _snprintf_s to minimize the amount of CRT functions we will have to replace later]
[27:22][Rewriting the config file after every debug UI action]
[28:17][We want the game to recompile itself]
[28:35][The platform layer will allow us to execute build.bat via DEBUGExecuteSystemCommand]
[32:25][The OS function we are looking for is CreateProcess]
[38:30][Testing it. It does not work]
[38:46][CreateProcess returned false]
[39:29][Using GetLastError to find out why]
[40:31][Providing an explicit path to cmd.exe]
[41:32][It works now]
[41:42][Toggling the value of DEBUGUI_UseDebugCamera in the config file]
[42:39][Introducing the Uber-Debug-UI!]
[43:08][Getting rid of the compilation window pop-up]
[44:20][Hiding the window using the wShowWindow flag inside the startup info parameter]
[46:40][It works!]
[46:50][Getting information about the state of the the compilation process]
[50:00][We will use WaitForSingleObject to find that information]
[52:54][Querying the platform layer about the state of the compilation process]
[55:48]["We don't care big it is"][quote 253]
[56:12][Implementing DEBUGGetProcessState]
[58:31][Using GetExitCodeProcess to confirm the completion of the compilation]
[1:02:05][Signalling the ongoing recompilation graphically]
[1:03:21][Find that platform_api doesn't have DEBUGGetProcessState][quote 254]
[1:03:38][Apologise for the slang][quote 255]
[1:04:49][Q&A][:speech]
[1:05:31][@powerc9k][Why be able to compile from the game if we can do it from the editor? Is it just to be cool?]
[1:06:30][@ChronalDragon][Compile in mr4th's editor and do all of the game development work from in-game?]
[1:06:51][@andsz_][I like how it's "STARTUPINFO", but "PROCESS_INFORMATION". Inconsistency even in a single small part of the WinAPI... Do such things annoy you in a "professional" API?]
[1:07:33][@Mr4thDimention][Why are we writing to a code file instead of just passing -D to the build line? Seems like it would be a little easier, although I have to admit you made that look pretty easy]
[1:08:24][@cubercaleb][Why not use system() instead of CreateProcess()?]
[1:09:43][@glaman1605][Do you plan on reading the original config file and then rewrite with modified values?]
[1:09:52][@TheSizik][Why not just set a boolean variable instead of recompiling a #define?]
[1:10:38][@ejunkie64][Will there be a dev console?]
[1:10:50][@Pseudonym73][Also, system() runs a program through CMD.EXE, which is yet another dependency]
[1:11:57][@Lkey144][The chat recommended CREATE_NO_WINDOW as a process creation flag. You could probably use that instead of the minimized window]
[1:12:38][@Trystan34][What is in the bat file that is run?]
[1:12:48][@powerc9k][Why does it zoom out?]
[1:13:02][@Radar_CS][Are you using sublime?]
[1:13:07][@Quantumplation][Can you add a radial menu for debug camera, instead of piggybacking off toggle graph? It's bugging me]
[1:13:19][Shut down][:speech]
