Changing to Static Frame Arrays | Handmade Hero Episode Guide

1:48handmade_debug.cpp: Initialise the ProfileGraph dimensions to something relatively large

4:01Run the game, see the profile at a more useable default size and set the stage for the day

5:42handmade_debug.cpp: Introduce DrawFrameBars which draws stacked bars for multiple frames

15:55handmade_debug.cpp: Call DrawFrameBars rather than DrawProfileIn

17:17handmade_debug.cpp: Cap the FrameIndex

18:02Run the game and see our stack

18:08handmade_debug.cpp: Increase the FrameCount to 10

20:50handmade_debug.cpp: Just set the RootNode to be the OldestEvent

22:03handmade_debug.cpp: Increase the FrameCount to 128

22:18Run the game and see a more granular view of what's happening over time

24:36handmade_debug.h: Remove debug_frame_region and MAX_REGIONS_PER_FRAME

25:58"None of that's a thing"^α

26:08handmade_debug.h: Introduce debug_element_frame to allow us to track and time events

31:07handmade_debug.h: Introduce FrameOrdinal and MostRecentFrameOrdinal and make functions in handmade_debug.cpp use it

38:09handmade_debug.cpp: Work on FreeFrame and FreeOldestFrame, and rework NewFrame as InitFrame

48:12handmade_debug.cpp: Introduce IncrementFrameOrdinal and GetCollationFrame

51:32handmade_debug.cpp: Work through compile errors

1:01:48Run the game and see that it is (almost) working

1:02:48Debugger: Break on FreeFrame and inspect the ordinals

1:09:33handmade_debug.cpp: Conditionally do a FREELIST_DEALLOCATE in FreeFrame

1:12:58handmade_debug.cpp: Scrutinise FreeFrame and do a ZeroStruct on *ElementFrame

1:14:48Run the game and reiterate the fact that we're leaking memory

1:17:10EnemyMouse Do you need to wrap that + FrameOrdinal in the FreeFrame function?

1:17:10EnemyMouse Do you need to wrap that + FrameOrdinal in the FreeFrame function?

🗪

1:17:48handmade_debug.cpp: Assert that FrameOrdinal is less than DEBUG_FRAME_COUNT

1:19:08handmade_debug.cpp: Keep track of the FreedEventCount

1:19:55Run the game, crash and find that we're freeing one more event than we're storing

1:21:10handmade_debug.cpp: Remove a FREELIST_DEALLOCATE

1:21:36Rebuild and run and find that the bug's gone

1:22:48zilarrezko I'm a bit behind on Handmade Hero, but do you typically bypass (for something like off-stream coding) all the simplified things like rendering a bitmap like how you were doing (DrawBitmap, like on episode 39), and go straight to the renderer? But as well as other things like structured assets and the like?

1:29:07handmade_debug.cpp: Reenable the profile lanes

1:30:35Run the game, see the multiple lanes, enable the software renderer and crash

1:31:10handmade_debug.cpp: Disable the recursion for now and run the game

1:32:39zilarrezko What if you aren't really learning from Handmade Hero? Where I've gone through episodes 1-28 about four times and I thought I knew how to do so. I tried to make the simplified win32 layer to get to the independent layer, and I found that I couldn't do it. The documentation was rough and I forgot what things did what. What would you say to people who find that they aren't learning?
