[1:28][Recap and set the stage for the day]
[3:24][handmade_sim_region.cpp: Investigate the glitch in the room-based camera movement]
[6:23][Blackboard: How the camera was being moved]
[7:27][handmade_sim_region.cpp: Correct the displacement and run the game]
[11:14][Blackboard: Camera control, hysteresis and perception grammar]
[20:05][Blackboard: Hysteresis]
[25:38][Blackboard: What we need hysteresis for in Handmade Hero]
[30:18][handmade_world_mode.h: Add CameraOffset to game_world_mode in order to decouple the camera and the simulation region]
[33:32][handmade_world_mode.cpp: Test offsetting the camera]
[38:19][handmade_sim_region.cpp: Introduce RoomDelta and hRoomDelta to make it easier to tweak values]
[40:29][Run the game and try moving between rooms]
[40:31][handmade_sim_region.cpp: Displace the camera away from the hero]
[41:14][handmade_sim_region.cpp: Scroll the camera halfway into the apron]
[47:04][Run the game and see the camera's half-interpolation]
[47:22][handmade_sim_region.cpp: Scroll the second half of the transition]
[48:18][Run the game and see the full scroll in action]
[50:33][handmade_sim_region.cpp: Tune the camera control]
[54:22][Blackboard: Parabolic arc equation]
[59:24][handmade_sim_region.cpp: Give the camera this parabolic arc]
[59:52][Run the game and enjoy the camera movement]
[1:01:48][handmade_sim_region.cpp: Update the Entity->P before computing the CameraOffset]
[1:03:55][Run the game and see that the glitch is gone]
[1:04:05][Q&A][:speech]
[1:05:00][@cubercaleb][Are you concerned about the player seeing outside the boundaries of the map or seeing into other rooms when the camera zooms out?]
[1:05:22][@gasto5][So, no more smooth scrolling?]
[1:05:47][@soysaucethekid][I know the rooms are going to fit the screen, but will there be variable sized rooms with the camera making it fit to the screen?]
[1:06:49][@dragonkinn02][When thinking of enemies, would you have classifications for AI, e.g. Level 1 approach constantly (zombie)? What would be the main levels you'd say for difficulty or reward feeling?]
[1:07:04][gasto5 When does he turn 39?]
[1:07:19][@popcorn][Have you seen the warp glitch from Link's Awakening? How would you avoid that?]
[1:09:29][@popcorn][You press start when before you enter a room and the link will end up on top of the screen]
[1:10:27][Blackboard: Our coherent sense of world space vs What may be happening in Link's Awakening]
[1:13:07][@sgtcarnaval][If you want a good hysteresis example a heater controller does the job]
[1:14:13][We are done][:speech]
