[1:00:40][Q&A]
|
||
|
|
[1:01:23][Why use real physics and not something custom you can handtune?]
|
||
|
|
[1:06:59][Why not add an opposite directional deceleration when collisions occur?]
|
||
|
|
[1:07:29][Are you concerned that actual physics will retract from the beauty and elegance of the worlds greatest jump code?]
|
||
|
|
[1:08:06][What would you need to store if you wanted to rewind time ala Braid?]
|
||
|
|
[1:12:53][Is the character a bitmap?]
|
||
|
|
[1:13:22][Are we going to normalise the vector from the input, instead of having a special case for diagonals?]
|
||
|
|
[1:14:01][Will there be a map function to help determine terrain for friction and collisions?]
|
||
|
|
[1:14:37][Why v2 instead of vec2 or vector2?]
|
||
|
|
[1:15:13][Why not break the code into smaller functions?]
|
||
|
|
[1:16:36][Shouldn't you use a max speed variable?]
|
||
|
|
[1:17:32][Someone: Friction negative acceleration based on current velocity would feel better]
|
||
|
|
[1:18:06][Can you derive the 1/2at^2 part of the position equation again?]
|
||
|
|
[1:23:54][Do you think something like bullet or box2d for player movement is appropriate?]
|
||
|
|
[1:25:38][When would you use other integration methods?]
|
||
|
|
[1:34:20][Will we use rigid body even after the hero is bouncy and all that?]
|
||
|
|
[1:35:00][Correction on question from someone]
|
||
|
|
[1:35:49][If we had terrain (ice or mud), we could have an easy convincing example]
