[58:54][Q&A]
|
|
[59:43][@badflydog][Wasn't today an off-day?]
|
|
[1:00:09][@cubercaleb][Can the compiler really mess up the pointer arithmetic? I mean, it is just integer ops, can't be that hard to mess up]
|
|
[1:02:28][@longboolean][So is the way to fix the snake from getting stuck to just allow it to run over itself or to make the snake AI smart enough to not trap itself?]
|
|
[1:03:48][@busy_beaver][I've recently watched your video on the GJK algorithm, it's great, thanks for that! Did you also do a video on the EPA algorithm?[ref

|
|
[1:04:02][@sir_kane][Will the snake head be able to move to the position of its last segment? So it can go in a circle / loop]
|
|
[1:04:50][@sssmcgrath][WTF you did a video on GJK? What other explanation videos have you done?]
|
|
[1:05:09][@paradjanin][Are you going to implement every AI thing in brain entity? When does path-finding and rest of AI coming on schedule? Also can you say some good reference book for AI? Cheers, Casey]
