[1:41:48][Q&A][:speech]
[1:42:42][@insobot][Q: Celeron ftw. FailFish?]
[1:42:57][@neitchzehrer][Q: Are you planning on having a jump command?][:"input handling" :movement]
[1:43:20][@garryjohanson][Don't even remember what a Celeron is]
[1:44:32][@nxsy][Q: There were some questions around b32x vs. b32 at some point][:language]
[1:45:04][@Miblo][Q: How about a dive and slide command?][:"input handling" :movement]
[1:45:21][@jamoflaw][Q: Are you planning on implementing a control remapping interface?][:"input handling"]
[1:45:38][@m0re85][Q: I know your view on comments but I often see you asking yourself "what was all that about?" when looking at old code. Wouldn't it be beneficial to comment non-obvious stuff?][:language]
[1:46:15][@shadowpro67][Q: What is the reason of pure C? I think C++'s oop and procedural coverage much better][:language]
[1:46:30][@x13pixels][Q: If you don't care how much space a bool is, why not use b8x?][:language]
[1:47:14][@mrpque][Q: Will you eventually make these input commands event driven rather, now that multiple sources of input are being accounted for?][:"input handling"]
[1:47:45][@yourmoviesbaddotnet][@handmade_hero What do you think are the disadvantages of C++ compared to C? Isn't C basically a subset of C++?][:language]
[1:50:21][@longboolean][Q: Something I thought of, of coarse it is a gameplay thing totally up to you. You could have the dodge double as an attack or have it push enemies away (or something) in the direction of the dodge][:"input handling" :movement]
[1:50:49][@ricecream][Q: Since you interviewed Pat Wyatt in 2015 HandmadeCon, have you ever thought about copying the Guild Wars faux Z-axis configuration?]
[1:51:50][@vateferfout][Q: What is happening with C++ templates that shouldn't be? Isn't it just generating code based on the template parameters?][:language]
[1:53:46][@wubbleduff][Q: What do you think about entity component systems as the engine architecture? How would you implement this if you don't use inheritance?][:"entity system" :language]
[1:54:25][@steamymcfly][Q: I recently learned about Imperfect Shadow Maps, I wonder if that could be a substitute for raycasting in the current :lighting system (at least on the GPU)?][:rendering]
[1:55:54][@strangezak][400 viewers today. That's a lot more than usual!]
[1:56:16][@theflame937][Q: Even if you don't do network for the game, will you do some lecture about it?][:networking]
[1:59:22][@mextrox][Q: What are your current thoughts on jai?][:language]
[2:00:09][@ricecream][Q: With the capabilities of mobile games exponentially increasing, what are the decision factors that result in games being ported to mobile?]
[2:03:18][@maxkaren][Q: What are your thoughts on Rust?][:language]
[2:03:25][@jim0_o][Q: What was it C was missing that makes you compile using C++?][:language]
[2:04:37][@dudeinbasement1][@handmade_hero stb doesn't do hinting, is there another lib that supports small text?][:font]
[2:05:35][@neitchzehrer][Q: How many types of enemies are you planning on having?][:"entity system"]
[2:05:42][@keepingtrckofthisacct][@handmade_hero How long have you been coding?]
[2:05:59][@warner][@handmade_hero Kind of off-topic question but here it goes: I've been in the gamedev industry working with studios, but now I decided to make an independent game of my own, and I kinda want to make a Kickstarter. Do you have any recommendations on that?]
