Disabling Sort for Debug Overlays — Handmade Hero — Episode Guide

0:08Recap and set the stage for the day

1:03Consider how to address the problem of sorting the debug overlay

3:26Run the game, toggle on the sort groups and see the extent of the sorting in the debug overlay

4:34build.bat: Temporarily switch to -O2, run the game and consult the profiler

5:50handmade_debug.cpp: Consider how DrawFrameBars() could aggregate the rectangles

7:14handmade_render_group.h: Introduce render_entry_rectangle_batch and render_entry_bitmap_batch structs

10:28handmade_debug.cpp: Make DrawFrameBars() initialise a batch to pass to PushRect()

13:15handmade_render_group.cpp: Begin to implement BeginRectangleBatch() and EndBatch()

16:41handmade_render_group.h: Introduce rectangle_batch struct

17:33handmade_render_group.cpp: Implement BeginRectangleBatch() as NewRectangleBatch() and leave out EndBatch() for now

22:03handmade_render_group.cpp: Consider how the SortKey aggregation works

25:23handmade_render_group.cpp: Make NewRectangleBatch() take SortZ and introduce a version of PushRect() that takes a rectangle_batch

33:30handmade_render_group.cpp: Consider how to aggregate the bounds

35:02handmade_render_group.cpp: Revert everything, in favour of turning off the sorting for the debug overlay

38:20handmade_render.cpp: Enable SortEntries() to skip sorting and simplify BuildSpriteGraph()

44:31handmade_render.cpp: Introduce UnsortedOutput()

47:22Run the game and consult the profiler

47:38handmade_render_group.cpp: Make PushSortBarrier() take a TurnOffSorting boolean and DEBUGEnd() set that value

50:55Run the game and find that the debug overlay is now unsorted

51:51handmade_debug_ui.cpp: Change the order in which TextOp() and BasicTextElement() draw

53:00Run the game and consult the profiler

54:18handmade_debug_ui.cpp: Enable the tooltips to be drawn last

56:26handmade_debug_ui.cpp: Introduce DrawTooltips() and rework AddTooltip()

1:01:52handmade_debug.cpp: Make DEBUGEnd() call DrawTooltips()

1:03:03Run the game and see the tooltips correctly hovering

1:05:39anonymous519 Could you talk a bit about the metaprogramming stuff you use at work? I'm kind of annoyed at the limitations of C/C++ and it looks like the JAI compiler won't be released anytime soon. Do you actually parse the code and construct an AST, or is it simpler than that?
