Debug UI State Caching — Handmade Hero — Episode Guide

0:59Recap our current situation

2:19Blackboard: Breadth-first vs depth-first tree traversal

8:46Debugger: Step into DEBUGDrawMainMenu and hunt for the hierarchy

13:25handmade_debug_variables.h: Make DEBUGAddVariable call the correct Context

13:38handmade_config.h: Manually rewrite the config

14:42Debugger: Step through and hit a first-chance exception

15:20Debugger: Inspect the DebugState->RootGroup

16:33handmade_debug_variables.h: Set Link->Var in DEBUGAddVariableToGroup

16:49Run the game and find it's looking a little bit better

17:19handmade_config.h: Ensure that the write-out worked correctly

17:43handmade_debug.cpp: Test for View->Collapsible.ExpandedAlways to be true

19:17Run the game and find that everything is collapsed

19:37handmade_debug.h and handmade_debug.cpp: Add debug_view Dummy to debug_state and make GetDebugViewFor return it

20:10Run the game and see the debug menu expand briefly

20:28handmade_debug.cpp: Finish implementing GetDebugViewFor

24:29Run the game and see that it's almost working fine

24:45handmade_debug.h: Consider storing the debug_view in debug_variable_link

26:55handmade_debug.h: Introduce debug_id

27:51handmade_debug.cpp: Pass ViewID to GetDebugViewFor

28:21handmade_debug.cpp: Introduce DebugIDFromLink

29:15handmade_debug.h: Add debug_id ID and debug_variable *Var to debug_interaction

30:12handmade_debug.cpp: Revert the code in DEBUGEndInteract and DEBUGInteract

31:07handmade_debug.cpp: Introduce VarLinkInteraction in order to compress these routines

33:48handmade_debug.h: Add debug_view *ViewHash to debug_state

35:40handmade_debug.cpp: Implement a hash function in GetDebugViewFor

40:33handmade_debug.cpp: Introduce DebugIDsAreEqual

41:25Run the game and see that our stuff works, except for indentation

42:29handmade_debug.cpp: Set the Layout.Depth in order to fix the indentation

43:48Run the game and see that the indentation is working pretty well

44:42handmade_debug_variables.h: Investigate why the Real32 isn't working correctly

46:08handmade_config.h: Try manually adding .0f to DebugCameraDistance

46:35Run the game and find that DebugCameraDistance is working

47:07handmade_debug.cpp: Reimplement tear-offs

50:27handmade_debug_variables.h: Introduce DEBUGAddVariableToDefaultGroup

51:30Run the game and find that the tear-off behaves as it did before

52:18handmade_debug.cpp: Grab the correct group in DEBUGDrawMainMenu

53:38Run the game and tear off specific values

54:18handmade_debug.h: Make DebugIDFromLink and VarLinkInteraction take the Tree

55:35Run the game and see that the state is isolated

58:14mykevelli Pure design question. In GetDebugViewFor() your method is named such that it's a query but it appears to be a command in some cases (in that it changes the state of the system). I've heard that you typically want to avoid this. Do you agree? Is there a reason you did this?

59:53elxenoaizd Do you think learning all the algorithms and data structures is a must, or is it OK to learn them when the need for one of them rises? Or is it one of those things that you have to learn beforehand in order to know if you need them or not?

1:05:29elxenoaizd I would like to be a tools programmer / game tech writer like you, but I'm still learning things so I'm not fully qualified to work as one. I'm thinking of working in a simple game company where the qualifications aren't so hardcore (maybe they use Unity or whatever), and at the same time do my private low-level self-learning. Good idea? Yes / No
