Preliminary Asset Structuring — Handmade Hero — Episode Guide

2:37Recap and set the stage

5:19Blackboard: "One in, One out"

7:46Blackboard: Only load once!

9:16Outline our tasks for the day

10:05handmade.cpp: Get TopDownAlignY back in

12:19Run the game to see the correct alignment

12:27handmade.h: Make things only load once

14:05handmade.cpp: Check to see if the asset in question is loaded

16:14handmade_intrinsics.h: Introduce AtomicCompareExchangeUInt32

19:05Compile and run

19:41FillGroundChunk will render incorrectly if the bitmap to be composited doesn't exist

21:42handmade.cpp: Only mark the ground chunk as having been filled once we know it has been

22:19handmade_render_group.cpp: Introduce AllBitmapsValid (AllResourcesPresent)

23:50Add MissingResourceCount to render_group

24:31Problem: With ground chunks being rendered on a separate thread, they could potentially be evicted at the wrong time

25:49Possible solutions to this problem

28:09handmade_render_group.cpp: Introduce CleanupRenderGroup

30:12handmade_render_group.h: Add game_asset_id to render_entry_bitmap

31:27handmade_render_group.cpp: Introduce UnlockAsset in CleanupRenderGroup

32:19Introduce LockAsset in PushBitmap

33:09Assess this locking implementation and undo it

37:06handmade.h: Introduce AssetState_Locked in asset_state

38:06Add asset_state FinalState to load_asset_work

39:03handmade.cpp: Assess what DEBUGLoadBMP is doing and consider what to do next

42:12handmade.h: Expand the notion of game_asset_id to be more generic

43:15Introduce asset_bitmap_info

44:24Introduce asset_tag

45:08Talk about creating a table of assets which provides semantic information to the code

46:22handmade.cpp: Discuss how this semantic information could be used by the world generation code

48:09Assets: Take a look at the art assets

49:06handmade.cpp: Introduce PickBest to rank assets according to the given criteria

53:39Explain how PickBest could work

55:50handmade.h: Introduce asset_group

56:50Get it compiling and leave it for now
