Drawing Multi-frame Profile Graphs | Handmade Hero Episode Guide

1:04Recap and set the stage for the day

3:29Apologise to folks not on the 4coder bandwagon yet^α

3:37handmade_debug.cpp: Consider how to unify Element creation

10:26handmade_debug.h: Add RootProfileElement to debug_state and pass that down the profiler system

14:38Run the game and make sure that it works

16:26Debugger: Step into RootProfile and erroneously follow the ParentGroup path

17:20"Arrrgggghhhhhh"^β

18:12Make this a very quiet, dignified edit^γ

18:24handmade_debug.cpp: Do AddElementToGroup in the CreateHierarchy path

18:47Run the game and see that we're in better shape

19:21handmade_debug.cpp: Simplify the ViewingElement code using RootProfileElement

20:42Opine the low resolution^δ

21:03handmade_debug.cpp: Simplify DrawFrameBars

26:11Blackboard: How the events are stored

28:33handmade_debug.h: Consider doing StoreEvent directly into the Element, without adding it to a Parent in CollateDebugRecords

30:31Blackboard: Why this might not work

32:12handmade_debug.cpp: Use debug_profile_node in DrawFrameBars

34:22Run the game and stress test the profiler

39:27handmade_debug.cpp: Switch to DrawProfileIn and make it take a debug_element RootElement

41:33Run the game and view the profiler with the old display

42:18Blackboard: Gracefully handling multiple events on a single frame

45:20handmade_debug.h: Remove AggregateCount from debug_profile_node and pack it a little differently

48:12handmade_debug.h: Remove TotalClocks from debug_element_frame

50:12handmade_debug.cpp: Introduce GetTotalClocks in order to compute TotalClock on demand

53:53Run the game and make sure the profiler still works

54:04handmade_debug.cpp: Space the EventRects based on the TotalClock

58:38Run the game and view our beautiful profiler

1:01:30cvaucher Reasons performance was so bad with the new debug view? Isn't this still way fewer tris than a typical 3D game? Is the framerate reasonable if you switch to solid rectangles vs outlines?

1:04:28Longboolean Right now the outlines on the profiler overlap each other. Makes it a little harder to make out the colors (or the change from one to the other). The obvious solution would be to draw them with a slight offset from the last each time, but are there any problems with that once the rectangles get really small?
