[0:14][Recap and set the stage for the day]
|
|
[1:42][Run the game and consider the plan for implementing multiple sim regions]
|
|
[5:47][handmade_world_mode.cpp: Consider how the UpdateAndRender*() functions are currently operating, and whether or not to split them up]
|
|
[11:24][handmade_brain.cpp: Look into why RenderGroup gets passed down to the brain]
|
|
[12:45][handmade_brain.cpp: Prevent ExecuteBrain() from setting AlwaysBehind and AlwaysInFrontOf, and run the game to see how the body and head are sorted]
|
|
[14:21][handmade_world_mode.cpp: Carve off the rendering code in UpdateAndRenderSimRegion() and determine which of its arguments may be optional]
|
|
[21:31][handmade_entity.cpp: Do that same process for UpdateAndRenderEntities()]
|
|
[26:10][handmade_world_mode.cpp: Run the game, then toggle off the rendering in UpdateAndRenderWorld()]
|
|
[27:05][handmade_brain.cpp: Make ExecuteBrain() only run the controller code if it has an Input]
|
|
[30:34][handmade_world_mode.cpp: Make UpdateAndRenderSimRegion() only process the mouse if it has Input]
|
|
[32:41][handmade_world_mode.cpp: Make UpdateAndRenderWorld() call UpdateAndRenderSimRegion() twice, run the game and see what happens]
|
|
[35:38][handmade_world_mode.cpp: Make UpdateAndRenderWorld() do an UpdateAndRenderSimRegion() on a second region]
|
|
[36:58][Run the game and zoom out to see two regions being simulated]
|
|
[38:16][Q&A][:speech]
|
|
[39:28][@f1aw][Did you make that debug UI yourself?]
|
|
[40:12][@nyeecola][Have you thought about refactoring your "brain" code to make use of virtual methods? Switch statements on "type" is basically replicating the type system and is a bit of a code smell]
|
|
[44:16][@montify][Do you use keyboard only at your day job? Are you faster without the mouse?]
|
|
[44:58][@nxsy][I missed the reason the two areas on the screen are discontinuous. Are these two sim regions of a larger world?]
|
|
[45:26][Run the game in -O2 and traverse the world towards the other sim region]
|
|
[47:42][@longboolean][What do you think about changing float values in the debug system by the distance you drag? Example: longer drag distance == bigger increments / decrements of the value, shorter drag distance == smaller increment / decrements]
|
|
[49:04][@nambitable][Couldn't you use CMake to generate visual studio solutions for windows?]
|
|
[50:36][@septumtesseract][What books do you recommend for C programming?]
|
|
[51:41][@soysaucethekid][How about for learning OpenGL?[ref
