[0:08][Welcome back after having moved to the Molly Rocket offices]

|
[0:45][On switching to a full 3D pipeline]

[9:58][todo.txt: Consult the TODO list]
|
|
[11:53][Blackboard: Sim Region and World]
|
|
[14:27][Blackboard: Creation]
|
|
[16:26][Consider how the entity (un)packing currently works]
|
|
[19:00][handmade_sim_region.cpp: Pull in the entity packing functionality from handmade_world.cpp]
|
|
[22:54][handmade_world.cpp: Rename PackEntityIntoChunk() and PackEntityIntoWorld() to overloaded UseChunkSpace() functions]
|
|
[24:43][handmade_world_mode.cpp: Consider allowing many entities to be stuffed into a sim region]
|
|
[27:24][handmade_world_mode.cpp: Simplify BeginEntity() and EndEntity()]
|
|
[29:05][handmade_sim_region.cpp: Introduce CreateEntity()]
|
|
[30:07][handmade_sim_region.h: Add a NullEntity to the sim_region struct for CreateEntity() to use if we've hit the MaxEntityCount]
|
|
[33:30][handmade_sim_region.cpp: Consider how to insert the entity into the hash table]
|
|
[36:25][handmade_sim_region.cpp: Reorganise BeginSim() to only add an entity if there's room for it]
|
|
[37:54][handmade_sim_region.cpp: Introduce AddEntityToHash() for CreateEntity() to call]
|
|
[40:56][handmade_world_mode.cpp: Introduce AllocateEntityID() for BeginEntity() to call]
|
|
[41:34][handmade_world_mode.cpp: Make PlayWorld() create a dummy sim region for BeginSim() and EndSim() to use]
|
|
[47:01][Run the game and see what we've destroyed]
|
|
[48:30][handmade_world_mode.cpp: Make AddPlayer() set and unset the creation region]
|
|
[49:16][Run and investigate what else is failing]
|
|
[50:17][handmade_sim_region.cpp: Make TransactionalOccupy() check that we have a desired traversable_reference]
|
|
[52:18][Step into EndSim() and inspect the Region and Entity]
|
|
[56:15][handmade_sim_region.cpp: Consider removing ChunkDelta from EndSim()]
|
|
[1:00:22][Step back into EndSim() and inspect the DestE and Entity]
|
|
[1:01:11][handmade_world.cpp: Prevent UseChunkSpace() from taking a sim_region]
|
|
[1:02:09][Q&A][:speech]
|
|
[1:03:16][handmade_sim_region.cpp: Comment out the MaxEntityVelocity assertion in MoveEntity(), run the game and continue investigating]
|
|
[1:04:35][handmade_sim_region.cpp: Make GetSimSpaceTraversable() only operate if it has an Entity, run the game and see the cool]
|
|
[1:05:24][@snoringtortoise][Did you resolve the kerning / horizontal advance for kanji characters? I found when implementing it myself on OSX (at the font table level) that Arial doesn't actually have kanji in it. It seems Windows (and Mac - the higher level APIs like CoreText) load multiple font files for you if it detects that you are trying to load a codepoint that is outside the range of a particular font file]
|
|
[1:07:24][handmade_sim_region.cpp: Look through EndSim()]
|
|
[1:09:02][@cyberpunkhobo][Can you explain what the idea is behind using a zero-sized sim region bounds?]
|
|
[1:10:12][Run the game and note how everything is gravitating towards that lower-left area]
|
|
[1:11:48][handmade_world_mode.cpp: Make EndEntity() correctly compute the Entity->P]
|
|
[1:14:01][Run the game and see that we're a little better]
|
|
[1:17:18][Consider why other entities are able to traverse the trees, while we aren't]
|
|
[1:19:08][@invinciblechaz][I've just started watching this stream. How often have you needed to refactor major parts of your code?]
|
|
[1:27:35][@thenoble1][Is the ms counter in the corner the render time for the frame?]
|
|
[1:30:18][build.bat: Switch to -O2, run the game and consult the profiler]
|
|
[1:32:11][@nxsy][Need OpenGL query timers]
|
|
[1:32:50][@phort99][I was about to ask what would happen if one of those snakey guys got themselves stuck in a corner, but I see one already did]
|
|
[1:34:59][@snoringtortoise][Off-topic: Since there wasn't any sound in the pre-stream, are there any sneak peaks regarding HandmadeCon you can give us?]
|
|
[1:38:21][todo.txt: Add the trees on traversables bug to the TODO list]

|
[1:39:10][Close it down][:speech]
