Waiting for Dependent Tasks on Metagame Mode Changes — Handmade Hero — Episode Guide

0:13Gift Received in the Mail: Owl of Shame Baby

2:06Recap and set the stage for the day

5:14Describe a threading bug in tasks which access the game's mode state and which persist

7:53Set out our choices for fixing this bug

11:23handmade.h: Add b32 DependsOnGameMode to task_with_memory

13:30handmade.cpp: Add Platform.CompleteAllWork and NeedToWait to SetGameMode

20:10Run the game and see that it does work right

20:33handmade_world_mode.cpp: Call PlayTitleScreen upon exiting from the game

21:03Debugger: Note that we may now be clearing a large block of memory to zero, run the game and use Debug->Break All to confirm that

23:06handmade.h: Introduce struct arena_push_params and inline arena_push_params in order to specify to the Push routines whether or not to clear to zero

27:14handmade.h: Introduce AlignNoClear and Align

29:51Propagate our new features to all of the Push calls that require it

35:38handmade.h: Introduce NoClear and finish writing these new functions

37:28Run the game and see that it runs much more snappily

38:01Consider making the memory arenas flow all the way down to the operating system level, making the debug system use a separate set of growable memory, and fixing the renderer's sorting

41:00handmade_render_group.cpp: Take a look at how the renderer currently works

43:32handmade_render_group.cpp: Consider removing the notion of the scanlines

44:21build.bat: Turn on HANDMADE_INTERNAL

44:57Run the game and watch our last frame time

46:16handmade_render_group.cpp: Remove the Even / Odd notion

47:49Run the game and enjoy our beautiful rendering

48:12handmade_optimized.cpp: Increment the Y counter by 1 rather than 2

49:13Run the game and see that we may have got a little faster

49:52handmade_render_group.cpp: Consider providing some way of knowing what we're sorting

53:11handmade_render_group.h: Add PushBufferElementCount to render_group to let us know how many elements have been pushed

55:27handmade_render_group.cpp: Introduce struct tile_sort_entry and use it in RenderGroupToOutput

1:00:55Run the game and see that it still works fine

1:11:40elxenoaizd Thanks, I was just curious in my console question. But sometimes I write utils that I would like to live in the background and not be visible on the screen, so I use a Windows application and hide the window. Is there any way to use a console instead and hide that (from taskmgr, etc.)?
