Cleaning Up Debug Globals — Handmade Hero — Episode Guide

0:14The only reason we are writing a user interface is to support our debug system

1:08Since we are the only users of the UI, we don't care if it's not intuitive, as long as it provides efficient interaction at a low implementation cost

3:08Recap

3:22Our approach to UI code

4:45Initial plan for today: Turning off the profiling visualization

7:09The debug UI can be a nice complement live code editing

9:19Change of plans: We'll get rid of the global debug variables

10:30Moving global variables inside the debug state

10:50Making sure all routines have access to the debug state

12:22It will be better to access the debug state through the DebugGlobalMemory. Implementing DEBUGGetState

17:15Testing. We got rid of those global variables

18:19The memory for the DEBUGRenderGroup comes from the transient arena. It should come from the debug arena

19:05Performing the DEBUGRenderGroup allocation inside DEBUGReset

20:06Access to the debug state should imply its initialization

22:20CollationArena will be a subarena of DebugArena

23:50Initializing the debug RenderGroup

24:32DEBUGReset will call BeginRender

25:42DEBUGOverlay will call EndRender

26:50The debug system shouldn't rely on the asset system; debug assets should be baked into the binary

32:45If we want the debug system to have access to the asset system, we need to make sure that the asset system is initialized first

33:58Implementing DEBUGStart and DEBUGEnd

39:09Testing. Live code editing and debug services work together now

40:10Resizing the profile view by changing its orthographic projection

44:43The mouse pointer position should also be transformed

45:27Controlling the placement of the profile rectangle

49:57Adjusting lane heights

53:37Displaying the profile rectangle so that we can debug the code that scales and positions it

56:41Fixing lane heights

1:01:40Miblo I appreciate that there are more robust ways of implementing such things, but would it be practical to use the debug data to drive some of the game's visual effects, e.g. fire or, more likely, some otherworldly magical entity or the display on an in-game computer? Maybe it could be a sort of Easter Egg for those of us who know how the game's made

1:02:45elxenoaizd There are magenta spikes in the debug graph that happens so fast we don't have time to click on them. How do we plan to catch those? Having the ability to step-over frame-by-frame would be useful, methinks. Another idea is to have the debug text left off at the last rect position we hovered at
