Defining the Ground — Handmade Hero — Episode Guide

3:56handmade.h: Check the TODO list

4:51Blackboard: The Ground

5:45Blackboard: Quake vs. Unreal

9:01Blackboard: Quake's "Constructive Solid Geometry" Paradigm

10:39Blackboard: Unreal's "Constructive Solid Geometry" Paradigm

12:21Blackboard: The difference between these two models

14:25Blackboard: Robustness vs. Efficiency

16:55Blackboard: Propose not talking about "Ground" or "Floors", but "Rooms"

31:46Blackboard: What happens when you step off a ledge?

35:16handmade_sim_region.h: Add EntityType_Space entity_type

36:17handmade.cpp: Implement the ability to create an EntityType_Space

40:41handmade.cpp: Introduce AddSpace

47:04handmade.cpp: Rename AddSpace to AddStandardRoom and add EntityFlag_Traversable

50:49Blackboard: No overlap between adjacent rooms

51:40Run the game and see some giant rectangleS

52:23handmade.cpp: Turn off AddStandardRoom

53:15handmade.cpp: Correct the sim_entity_flags settings

54:02handmade_sim_region.cpp: Check EntityFlag_Collides in CanCollide

54:42Run the game and find that we now correctly don't collide with the StandardRooms

54:50handmade.cpp: Introduce PushRectOutline

56:37Blackboard: Drawing out the PushRectOutline

57:38handmade.cpp: Continue writing PushRectOutline

59:13Run the game and find that we cannot see the outline

59:26handmade.cpp: Increase the thickness of PushRectOutline

59:50Run the game and find that we're only drawing one line

1:00:07Debugger: Step into PushRectOutline

1:02:10handmade.cpp: Multiply the Dim by half

1:02:59Run the game and see our correctly drawing outline
