Adding a Debug Frame Slider — Handmade Hero — Episode Guide

0:49Run the game and set the stage for the day

1:56"You feel me, dawg?"^α

2:47handmade_debug.cpp: Introduce case DebugType_LastFrameInfo and _DebugMemoryInfo and tie them into the system

6:12handmade_debug.cpp: Introduce BasicTextElement

7:50Hype 4coder and demo some indentation issues

9:24Compile and run and find that BasicTextElement does work

9:50handmade_debug.cpp: Propagate BasicTextElement

10:32handmade_debug_interface.h: Define our new DebugTypes and DEBUG_UI_ELEMENT

12:44Run the game and view the profiler

13:10handmade_debug.cpp: Investigate why the DebugTypes appear in reverse order

14:36handmade.h: #define DLIST_INSERT_AS_LAST

15:54handmade_debug.cpp: Make AddGroupToGroup call DLIST_INSERT_AS_LAST

16:27handmade_debug.h: Add ViewingFrameOrdinal to debug_state

17:48handmade.cpp: Add a DEBUG_DATA_BLOCK "Debug Control" for a FrameSlider

19:04handmade_debug.cpp: Implement DebugType_FrameSlider

22:04handmade_debug.cpp: Introduce DrawFrameSlider

26:11Run the game and see that we did totally mess it up

26:20"Nice work, Muratori. You're off the team"^β

26:25handmade_debug.cpp: Iterate through the for loop in DrawFrameSlider

27:10Song: 'Too Many Frames' by Casey Muratori

28:21handmade_debug.cpp: Make ViewingFrame yellow, the color of urine^γ

30:48Run the game, view the FrameSlider and explain what will happen when we run out of per-frame arena space

32:49handmade_debug.cpp: Switch to a smaller SubArena for the debug information

33:21Run the game and hit an assertion when we have insufficient memory to store the debug data

35:32handmade_debug.cpp: ZeroStruct the Frame

35:54Run the game and watch the FrameSlider as we run out of space to store the debug data

38:02handmade_debug.cpp: Provide the ability to interact with the FrameSlider

42:03Run the game and crash upon interacting with the slider

42:20"Who wrote this ridiculous code?"^δ

42:30handmade_debug.cpp: Put the interaction code in the correct place

43:01Run the game and interact with the slider

43:38handmade_debug.cpp: Replace MostRecentFrameOrdinal with ViewingFrameOrdinal

45:59Run the game and find that we can pick the ViewingFrame with the slider, but that the profiler expands weirdly

50:14Run the game and investigate why ToggleExpansion is happening

53:32handmade_debug.cpp: Conditionally set MostRecentFrameOrdinal if we're paused

54:10Run the game and admire the profiler

55:13handmade_debug.cpp: Implement the ability to pause the profiler

57:30Run the game and try pausing the profiler

58:21Demonstrate the fact that we track all of the data
