|
|
[1:19:22][Q&A][:speech]
|
|
[1:21:05][Why is the heros head 1.5 meters in diameter?]
|
|
[1:21:29][How would you handle concave objects with Minkowski?]
|
|
[1:22:41][Why isn't the game split up in smaller, more modular files?]
|
|
[1:24:51][Is the alpha channel in the art assets created by the artist?]
|
|
[1:25:21][How many years since you started doing games?]
|
|
[1:26:37][I usually just hope the framerate stays high enough for the velocity not to get too high]
|
|
[1:28:57][Can't you have multiple views of the same file with emacs?]
|
|
[1:29:26][Will you be able to use minkowski with rotating and diagonal objects?]
|
|
[1:33:30][How long have you been working on this game?]
|
|
[1:33:57][Is it possible to make an assert that lets you continue on failure?]
|
|
[1:34:17][Are you doing any cyclomatic complexity analysis?]
|
|
[1:34:43][How would you represent a large sidescroller 2D world?]
|
|
[1:35:43][Is it possible to determine the point of collision?]
|
|
[1:36:11][Seems like the inability to represent convex objects is a major for problem for physics]
|
|
[1:37:15][I meant determining the point of collision with the general GJK algorithm]
|
|
[1:38:27][Are we doing a Raspberry Pi port just for the heck of it?]
|
|
[1:39:24][Cyclomatic complexity: a direct measure of the number of linearly independent paths through the code]
|
|
[1:39:50][BeagleBone black is better than Raspberry Pi I think]
|
|
[1:41:01][Can't you do straight on hardware on the PC?]
