Making the Debug System CLANG Compatible | Handmade Hero Episode Guide

0:31Set the stage for the day with a few words on compiling for multiple platforms

3:20Determine to make the debug system compatible with CLANG

5:48handmade_debug_interface.h: Explain the RecordDebugEvent() and DEBUG_NAME macros

8:59Describe our problem and demo string concatenation

14:06Consult the GCC documentation (see Resouces, GCC Manual)

14:52handmade.cpp: Demo the difference between GCC's and Visual Studio's implementations of string concatenation

17:28Consider how to workaround the problem

26:07Consider adding support for constant string concatenation to CLANG

27:04handmade_debug.cpp: Reacquaint ourselves with the code

28:334coder feature request: A standard way to send a platform message to 4coder in order to jump to a file at a given line

31:16handmade_debug.interface.h: Consider having two versions of UniqueFileCounterString__()

34:25handmade_debug_interface.h: Add Name to the debug_event struct and make BEGIN_BLOCK and END_BLOCK take it

41:46handmade_debug.cpp: Change DebugParseName() to take a ProperName

45:34handmade_debug_interface.h: Make the TIMED_BLOCK macros take a Name

46:52Run the game to see what that produces

48:47Step through DebugParseName() and inspect what it does

50:31handmade_debug.cpp: Make GetElementFromEvent() set a Name rather than NameStartsAt

52:48handmade_debug.cpp: Make DEBUGInit() set the Name

54:04Run the game and see what we're recording

54:54handmade_debug_interface.h: Ensure that everyone is passing the correct information down

57:30Inspect the assembly for the debug system during the cutscene rendering

1:02:47Step through GetElementFromEvent() and StoreEvent() to see what they do

1:05:47handmade_debug.cpp: Make DEBUGEventToText() use our newly passed Name and run the game to see what it produces

1:07:41Determine that we've solved our problem and close the issue

1:11:22Run the game and assess our situation

1:12:48Determine to fix the camera tracking

1:15:03Step into UpdateCameraForEntityMovement() and investigate why the player is never being found by EntityOverlapsRectangle()

1:23:47handmade_sim_region.cpp: Make UpdateCameraForEntityMovement() test on IsInRectangle() rather than EntityOverlapsRectangle()

1:28:12Step into UpdateCameraForEntityMovement() and receive a positive result

1:29:46handmade_sim_region.cpp: Make UpdateCameraForEntityMovement() record the RoomDelta differently

1:32:50Run the game and find that the camera is incorrectly positioned

1:33:35handmade_sim_region.cpp: Make UpdateCameraForEntityMovement() correctly set the RoomRelP, run the game and find that it's having trouble snapping back

1:34:48handmade_sim_region.cpp: Change UpdateCameraForEntityMovement() to snap to the room centers

1:37:02Run the game and find that the camera snaps correctly

1:37:33handmade_sim_region.cpp: Enable UpdateCameraForEntityMovement() to interpolate between camera positions

1:38:29Run the game to see that it correctly interpolates between camera positions

1:38:54Consider supporting differently sized rooms

1:39:50handmade_world_mode.cpp: Make AddStandardRoom() take RadiusX and RadiusY in order to create variably sized rooms

1:48:13Run the game to see that we're creating rooms as we were doing

1:48:38handmade_world_mode.cpp: Enable AddStandardRoom() to align the rooms and support different radii

1:53:07Run the game to see what that does

1:53:36handmade_world_mode.cpp: Try changing the sizes of the rooms

1:55:08Run the game to find that we have different sized rooms

1:56:11handmade_world_mode.cpp: Enable AddStandardRoom() to know the sizes of abutting rooms

1:58:32Run the game to see our variably sized rooms and consider making the camera zoom to correctly frame the rooms

2:01:33highergravity Long time archive viewer, but first time live streamer! I have two pre-stream questions but I can never make the pre-stream time. 1) Do you have a strong opinion about why int *p is "superior style" than int* p, or are you impartial to whatever the developer prefers?

2:02:12Demo: Pointer declaration style

2:04:40highergravity 2) Do compiler optimisations (-O2) guarantee that the same output is generated for time-independent code? That is, does the out-of-order processing ever introduce some nasty logic / contol flow bugs that -Od wouldn't?

2:08:01mtsmox You said you didn't want to use PRETTY_FUNCTION because that wouldn't work because of duplicate GUIDs. But the only place where PRETTY_FUNCTION would have been used is in TIMED_FUNCTION, which should never be used more then once in any function anyway. So not using DEBUG_NAME in TIMED_FUNCTION would solve the problem. All the other calls to TIMED_BLOCK_ would still work with DEBUG_NAME and thus use the COUNTER to be unique. So I think the extra field for the Name is really not necessary.

2:09:43linike860 What is your opinion on Minkowski Portal Refinement for collision detection and response? I feel it is much nicer as it gives you much of the collision information (normal, depth, etc.) without having to implement an entire separate algorithm like GJK does
