33:26handmade_debug.h: Add *Event to debug_frame_region

34:27handmade_debug.cpp: Set ColorIndex to OpeningEvent->BlockName

35:15handmade_debug.cpp: Rename Source to Event

35:26handmade_debug.cpp: Change HotRecord to HotEvent

36:10handmade_debug.cpp: Remove the check on GlobalDebugTable

36:25Run the game and see that we're getting a lot closer

37:00build.bat: Remove TRANSLATION_UNIT_INDEX

37:22Run the game and check that it's still okay

37:25handmade_debug_interface.h: Remove debug_record and put GetController back into handmade_platform.h

38:08handmade_debug_interface.h: Move ThreadID and CoreIndex from threadid_coreindex to debug_event

39:07Run the game and see that all is working nicely

39:19handmade_debug_interface.h: Remove #define MAX_DEBUG_TRANSLATION_UNITS

39:50handmade_optimized.cpp: Remove DebugRecords_Optimized_Count

40:08handmade_debug.cpp: Remove DebugRecords nonsense

40:34handmade_debug_interface.h: Consider packing debug_event a little more

42:18handmade_debug.cpp: Add Var->BlockName back in to CollateCreateVariable

42:42Run the game and see "Hot Entity" again

43:03handmade_debug.cpp: Remove debug_event *Var

44:06handmade_debug.cpp: Do CollateAddVariableGroup rather than CollateCreateGroupedVariable

45:10handmade_debug.h: Remove DebugType_VarGroup from debug_type and call it OpenDataBlock everywhere

45:55Debugger: Investigate why BeginBlock is happening

48:42handmade_debug.cpp: Remove CollateCreateGroupedVariable

48:48handmade_debug.cpp: Assert that Link->Event->Type != DebugType_BeginBlock in CollateAddVariableToGroup

49:14Debugger: Inspect Stack and Depth

50:34handmade_debug.cpp: Try doing RestartCollation on every frame

52:02Run the game and find that it was an overwriting problem

1:06:59culver_fly Just asking, but is it worthwhile to put so much effort on the debug system at this stage? There's a lot of things you're doing right now that I'm not sure how it will help in the future (maybe just because I have never programmed games before), but if I as a newbie game programmer were to work on this, do you suggest going as far as you're going right now or proceed on the gaming part to see what I need first before doing it?
