Automatically Constructed Debug Hierarchies | Handmade Hero Episode Guide

0:02Intro

0:31Background on the number 219

1:10"You should fertilize that directory with human tears, and then you should see what grows from it. It will probably be black roses that crumble and blow away with the wind."^α

1:39"The whole point of the existence of this system is because humans are so fallible and always do everything wrong."^β

1:49Current state of the game when run

2:04Brief explanation of unlimited debug info storage system from yesterday

3:25Determining today's goal: bringing the debug system together

4:31Starting work on hierarchical debug event UI

4:52Describing how debug events should be grouped into a hierarchy of debug elements

6:43Changing terminology of root tree back to root group

7:23Re-enabling hierarchy generation for the new system

8:38Considering whether or not to add free-list for the debug info

9:25Updating AddVariableToGroup, CreateVariableGroup to work with elements in a tree hierarchy

12:31Splitting AddVariableToGroup into AddElementToGroup and AddGroupToGroup

13:49Noting names aren't stored in debug_variable_group, and fixing it

15:41Removal of CreateVariable

16:21Adding root variable group handling in GetGroupForHierarchicalName

17:37Creating root variable group

18:26Adding hierarchy lookup to GetElementFromEvent

19:25Thinking how BlockName and/or GUID should be used to create the hierarchy

22:14Use GetGroupForHierarchicalName when adding a new event to check for a parent group, and link them if there is one

23:43Enabling the drawing of the hierarchy

24:18Debugging crash due to not knowing how to draw certain debug elements

25:50Adding a default name for unhandled debug events to prevent crashing

26:09Running the game, now doesn't crash, but debug variables aren't listed

26:28"Sometimes even in the depths of despair, some little tiny thing goes your way, and the important thing to remember is not to let that go to your head"^γ

26:59Start looking into why debug variables aren't appearing

29:51"I want to break down in tears. I want to just give up and let the horrors of the world continue unabated. But instead what I'm gonna do is set a breakpoint on MarkDebugValue"^δ

30:09Add breakpoint to MarkDebugValue to see which events are getting through

30:46Explanation of the bug, partial fix by storing GUID in the event

31:49Rerunning the game, multiple events now correctly show up, but with incorrect text

31:57Storing BlockName into the event too, making the debug display slightly more correct

33:37Explaining how the debug names can be used to assemble the hierarchies

34:25Implementing the hierarchy building in GetGroupForHeirarchicalName

38:00Adding the GetOrCreateGroupWithName helper function

41:01Putting a name into the debug_variable_group struct, completing hierarchy creation code

44:03Adding a StringsAreEqual function with explicit length parameters

46:22Describing what more needs to be added for the debug hierarchy to display correctly

48:10Start branching the code to handle both single elements and hierarchies

51:39Running the game, now events are displayed hierarchically

53:53Adding interaction support to the hierarchical debug events

58:18Rewriting how groups are expanded

59:36Game running, interactions now working but with improper highlighting

1:01:43Debugging why multiple interactions are being highlighted as hot

1:02:11Found the bug

1:03:08Everything running correctly

1:12:22"We just have to have faith that The Variable is looking down on us from The Great Memory, and that if we all just work hard and try to be good people that eventually The Variable will let us into The Great Memory and we'll live in peace and happiness with all of our other discretized values."^ε
