Integrating Debug UI into Game Code | Handmade Hero Episode Guide

1:10"We will be in sync..."^α

1:34Recap and set the stage for the day

3:16Run the game and show that the picking system is kind of random and janky

5:58handmade.cpp: Look at the current picking system and consider what we'd like to do

9:14handmade.cpp: Decouple the hit testing and the output

13:41handmade.cpp: Use debug_id in order to unify the system

16:14On the uses of pointers as a location in memory and a name

20:24handmade.cpp: Make DEBUG_HIT take LocalMouseP.z

23:34handmade_debug_interface.h: #define the necessary values and implement them

29:31handmade.cpp: Introduce DEBUG_REQUESTED

30:50handmade_debug_interface.h: Give debug_event the concept of a DebugID

31:51handmade_debug.cpp: Introduce DEBUG_HIT, DEBUG_HIGHLIGHTED and DEBUG_REQUESTED

33:12handmade_debug.cpp: Check for the existence of Memory in DEBUGGetState

35:26Run the game and hit an assertion

37:34handmade_debug.cpp: Replace the Assert in DEBUGGetState with a check for DebugState

38:10Run the game and find that the debug system highlights everyone

38:29handmade_debug.h: Add DebugInteraction_Select to debug_interaction_type

39:45handmade_debug.cpp: Introduce DebugIDInteraction based on VarLinkInteraction which takes the Type and ID

41:47handmade_debug.h: Add debug_id SelectedID to debug_state

42:03handmade_debug.cpp: Write DEBUG_HIGHLIGHTED and DEBUG_REQUESTED

43:00handmade_debug.cpp: Introduce IsSelected

44:56Run the game see that it doesn't look very exciting

45:09handmade_debug.cpp: Clear the NextHotInteraction when we end

45:47Run the game and see that we're in much better shape

48:37handmade_debug_interface.h: Make DEBUG_HIGHLIGHTED take *Color

48:47On compiling something out and using ... as the parameters

49:17handmade_debug.cpp: Highlight entities in different colours

51:33Run the game and see that the picked entity persists

52:08handmade_debug.cpp: Make DEBUG_REQUESTED work on both the selected and hovered entities

53:00handmade_debug.h: Add SelectedIDCount to debug_state

53:32handmade_debug.cpp: Make IsSelected loop over all of the SelectedIDCounts

54:11handmade_debug.cpp: Introduce ClearSelection and AddToSelection

55:59handmade_debug.cpp: Make DebugInteraction_Select handle multiple selections

57:40Run the game and select as many things as we want
