[0:15][Recap]
[1:07][Casey talk about "The coincidence of how people use their TODO notebook"]
[2:52][Bug fix: Remove the code we left when we were playing around with familiars]
[5:39][Decide what to do today: Clean up things by using v3]
[6:01][Get rid of the struct "world_difference" and fix other places we were using it]
[8:16][handmade_world.h: Change ChunkSideInMeters to v3]
[9:45][handmade_math.h: Implement the Hadamard product]
[11:16][handmade_math.h: Clone v2 operations for v3]
[15:14][handmade_world.h: Offset_ is v3 now]
[16:00][Point out the puzzler from world_position can be solved because we now no longer operate on entities without bringing them into the sim_region]
[17:28][Back to deal with compiler errors]
[23:37][The ground plane should not be the negative bottom sides of Tiles because we want to prevent things from accelerating near the Z bound]
[26:12][handmade_world.h: Tidy up the function ChunkPositionFromTilePosition]
[29:14][handmade_math.h: Use anonymous struct in union to grab part of the elements we are interested in v3]
[31:54][handmade_math.h: Make a v3 "constructor" that append a v2 with a real32 value]
[33:05][handmade_sim_region.h: Upgrade P/dP in sim_entity to v3]
[33:47][Keep on dealing with compile errors]
[35:37][handmade_math.h: rectangle3]
[36:34][handmade_math.h: AddRadiusTo should take a vector as a parameter]
[37:54][handmade_sim_region.h: Upgrade MoveEntity routine to v3]
[43:20][Get rid of GetCameraSpaceP]
[43:35][Keep on cleaning up]
[47:20][Program now can be compiled]
[47:37][Run the game and find out there is absolutely nothing except our hero]
[48:01][Make sure that rectangle bound set up properly]
[48:33][Blackboard: Explain what we want to make sure in more detail]
[56:57][The bug might be Casey broke something in terms of how to store things into chunk position]
[58:13][Q&A][:speech]
[58:51][@plainflavored][Have you considered using macros that take a name and operator to paste in simple vector functions?]
[1:00:02][@llorton][What kind of almond milk are you drinking?]
[1:00:12][@donotputmeonpizza][Do you have any suggestions on how to keep up with your 5 episodes a week, when me and my friend have only started watching your videos from the beginning last week?]
[1:01:22][@ryanries][Why type 1.0f instead of 1.0?]
[1:02:28][@hexagonal_diamond][Have you considered writing tests?]
[1:05:36][@rsxole][Can you explain what your Z really means? If it's for separating levels, should tall walls be able to poke into the upper Z layer(s)?]
[1:06:36][Reminder: Monster that you fight on two floors at once, going up and down stairs to fight the bottom or the top]
[1:07:34][@xanthacroi][How do you tab between things so quickly?]
[1:08:39][@mickeyd32][How good of a computer do I need to smoothly code?]
[1:10:19][@saltattack][I love you... Will you marry me?]
[1:10:36][@nathyks][How smooth is it transitioning a knowledge of Python into C++]
[1:11:26][@apathydude][Have you thought more on how the Z-axis will look when finally implemented?]
[1:12:35][@biralx][When you work on a game do you work on one project or do they contract you for multiple projects?]
[1:12:50][@nicstop][Do you think about data locality all the time, to reduce cache misses?]
[1:14:37][@jkr2120][How long have you been programming?]
[1:14:50][@plainshane][Are you done working for real - made all your money, and this is just for fun / philanthropic reasons?]
[1:15:10][@duroate][How do you determine what gathers in a chunk with the Z-axis? Do you grab entities from all 6 sides of the chunk?]
[1:15:27][Blackboard: "Axis aligned bounding box"]
[1:18:11][handmade.h: TODO(casey): Minkowski inclusion test for sim region begin / updateable bounds]
[1:19:28][@hnau][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?]
[1:21:08][@drtwox][Do you think RK4 integration is "overkill" for a 2D game like Handmade Hero?]
[1:24:25][@mymlyreen][Hi, just tuned in so it might have been mentioned before, but why are you using assertions in non-test code?]
[1:29:38][@d7samurai][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?]
[1:31:13][Call it][:speech]
