1:37Blackboard: Position != Collision "Mesh"

9:13handmade_sim_region.h: Introduce sim_entity_collision_volume

10:54Blackboard: Two ways of storing this collision volume data

12:51handmade_sim_region.h: Introduce sim_entity_collision_volume_group

15:09Compile and be guided by the compile errors in replacing the Dim

15:43handmade_sim_region.h: Add WalkableDim to sim_entity

17:38handmade_entity.h: Use WalkableDim in GetStairGround

19:31handmade_math.h: Introduce GetBarycentric for rectangle2

20:18handmade_math.h: Introduce Clamp01 for v2

21:03handmade_sim_region.h: Add sim_entity_collision_volume TotalVolume to sim_entity_collision_volume_group

23:11handmade_sim_region.cpp: Pass sim_entity_collision_volume to EntityOverlapsRectangle

25:51handmade_sim_region.h: Specify that the VolumeCount is always expected to be greater than 0 if the entity has any volume

27:21handmade_sim_region.cpp: Iterate over the Volumes

28:04Blackboard: Collision detection is an o(n^2) problem

30:02handmade_sim_region.cpp: Continue writing this loop

45:57handmade.cpp: Use the WalkableDim to draw the Stairwell

46:56handmade.cpp: Implement MakeSimpleGroundedCollision

51:10handmade.cpp: Do InitializeWorld earlier

51:35Run the game and find that we're not totally busteD

52:27handmade.h: Flying things can now go over low walls

53:07handmade.cpp: Initialise the WalkableDim in AddStair

54:38handmade_math.h: Introduce ToRectangleXY

55:53Run the game and see that our stairwell is back

56:18handmade_sim_region.cpp: Reenable the stairwell collision

57:23Run the game and try jumping over the stairwell

58:24handmade.cpp: Implement MakeNullCollision

59:50Run the game and note the weird effect of gravity while falling down the stairwell

1:01:04handmade_sim_region.cpp: Set Drag.Z = 0.0f

1:01:49Run the game and fall down the stairwell
