58:09Do you use diagrams a lot in your actual work?

58:26What do you recommend for learning c++?

58:45Try setting handmade hero start at the midpoint between tiles

1:00:14What are your initial thoughts on DX12?

1:00:56Why is your code over 900 lines?

1:01:13How about using signed values for the top coordinates?

1:01:40Stream went offline

1:01:58Why don't you like private?

1:02:34Is there any background information you can give us new viewers?

1:02:59Do you see any complications broadcasting sound from float space in the next room?

1:05:23What is your preferred scripting language?

1:05:37I'm curious if you have to do with memory misalignment?

1:06:08Any reason you're making it somewhat more complicated than it should?

1:07:10How are you supposed to draw the game in Windows 10 without a HoloLens?

1:08:05Is the system rendering offscreen objects in the background?

1:08:31The struct name abc initialisation looks odd

1:09:15What's the estimated date for the release of Handmade Hero?

1:09:36Have you ever pair programmed?

1:09:47Do you go hard in the pain?

1:10:15Could you remove the old RenderWeirdGradient()?

1:10:30Why is there an issue with wrapping?

1:11:39Where did you get your education at?

1:11:48Does C handle pointers any different than C++?

1:12:15Do you use version control?

1:12:39Why not change the tilewidths and heights to 8x16 to wrap the camera with power of two?

1:13:55Can you explain how you use Minkowski addition in the collision?

1:15:19Are you eventually going to add tile entities?

1:16:15How much focus are you going to give to tile entities?

1:17:15How tall are you?

1:17:33What if you translate a 9x9 tilegrid to the player as origin before doing any world map?

1:18:08What do you use to draw?

1:18:49For wrapping you could just check if the new value is between uint_max and the nearest multiple of 9x17

1:19:11Can you explain what float-space is exactly

1:25:18Will you create a map editor?

1:25:34Seems like you could use bitfields or union to combine the different coordinates?

1:25:55What's the best way to learn how to code?

1:26:41I thought floats and doubles are the same speed in the FPU?
