Converting to Full 3D Positioning | Handmade Hero Episode Guide

0:15Recap

1:07Casey talk about "The coincidence of how people use their TODO notebook"

2:52Bug fix: Remove the code we left when we were playing around with familiars

5:39Decide what to do today: Clean up things by using v3

6:01Get rid of the struct "world_difference" and fix other places we were using it

8:16handmade_world.h: Change ChunkSideInMeters to v3

9:45handmade_math.h: Implement the Hadamard product

11:16handmade_math.h: Clone v2 operations for v3

15:14handmade_world.h: Offset_ is v3 now

16:00Point out the puzzler from world_position can be solved because we now no longer operate on entities without bringing them into the sim_region

17:28Back to deal with compiler errors

23:37The ground plane should not be the negative bottom sides of Tiles because we want to prevent things from accelerating near the Z bound

26:12handmade_world.h: Tidy up the function ChunkPositionFromTilePosition

29:14handmade_math.h: Use anonymous struct in union to grab part of the elements we are interested in v3

31:54handmade_math.h: Make a v3 "constructor" that append a v2 with a real32 value

33:05handmade_sim_region.h: Upgrade P/dP in sim_entity to v3

33:47Keep on dealing with compile errors

35:37handmade_math.h: rectangle3

36:34handmade_math.h: AddRadiusTo should take a vector as a parameter

37:54handmade_sim_region.h: Upgrade MoveEntity routine to v3

43:20Get rid of GetCameraSpaceP

43:35Keep on cleaning up

47:20Program now can be compiled

47:37Run the game and find out there is absolutely nothing except our hero

48:01Make sure that rectangle bound set up properly

48:33Blackboard: Explain what we want to make sure in more detail

56:57The bug might be Casey broke something in terms of how to store things into chunk position

1:19:28hnau I recently watched Jon Blow's talk on attempting deep work and became curious: Do you do anything similar from a psychological perspective, i.e. go dancing like Jon does or do you have some other relaxing / rewarding activity that helps to spawn creative thought or gain elusive insights into problems you are struggling to solve?

1:29:38d7samurai What about having two regions - one outer and one inner, include entities that move into the inner and exclude entities that move out of the outer - so there's a "margin" that allows some moving without ping-ponging right across a hard in / out line?
