[1:00:29][Q&A][:speech]
|
|
[1:00:58][@yoonfan][When I write event-driven code, I am often forced to use dynamic memory allocation to preserve some state until it is needed by the callback. How do you deal with those situations?]
|
|
[1:03:35][@robrobby][Would the Handmade debug view enable viewing structs like world mode?]
|
|
[1:03:58][@longboolean][When moving diagonally, will it be clear to the player which way the body will go to get to the diagonal entity? Right now it seems kind of random]
|
|
[1:05:55][handmade_world_mode.cpp: Introduce DesiredDirection in order to make the body move more directly to the head]

|
|

|
|
[1:16:43][@chronaldragon][This may just be an illusion but it looks like the body is snapping to the corner of tiles. Usually in tile-based games, entities occupy the center of a tile. Is this intentional?]
|
|
[1:17:22][handmade_world_mode.cpp: Make MakeSimpleFloorCollision draw the tiles]
|
|
[1:18:01][Run the game, see the tiles and move around on them]
