Handling Traversables in the Collision Loop — Handmade Hero — Episode Guide

4:29Blackboard: Augmenting the collision loop to loop over two types of t value

5:10handmade_sim_region.cpp: Introduce tMax

5:58handmade_sim_region.cpp: Consider how best to modify this routine

11:03handmade_sim_region.cpp: Loop over the Walls to get all of the data taken by TestWall

15:15handmade_sim_region.cpp: Introduce test_wall

15:56Run the game and make sure it's still working

16:14handmade_sim_region.cpp: Embed TestWall directly in the collision loop

17:45Run the game and test the collision

18:52handmade_sim_region.cpp: Test tMax

22:03handmade_sim_region.cpp: Massage the routine

24:27handmade_sim_region.cpp: Implement the tMin vs. tMax logic

26:27handmade_sim_region.cpp: Write the tests for Overlap and EntityFlag_Traversable

28:09Encourage us not to be scared of solving complex problems

32:49handmade_sim_region.cpp: Improve the overlap test

35:57handmade_sim_region.cpp: Introduce EntitiesOverlap for this overlap test

38:42handmade_sim_region.cpp: Make EntitiesOverlap take an Epsilon enlargement region

40:06handmade_sim_region.cpp: Reenable the EntityFlag_Traversable test and use EntitiesOverlap

41:52Run the game and find that we can't get past our tMax

42:27handmade_sim_region.cpp: Move tMin, tMax and HitThis inside the loop

44:03handmade_sim_region.cpp: Rethink the logic of the collision routine

46:25Run the game and find that we're working a little more properly

46:44handmade.cpp: Only create walls in the first room in order to test the new world definition

47:07Run the game and test the collision detection

50:04handmade_sim_region.cpp: Increase the size of the overlap Epsilon

51:55Debugger: Step into the collision routine

54:03handmade_sim_region.cpp: Initialise tMaxTest to our current tMax

54:34Run the game and find that everything seems pretty good, but still a little janky

54:55Set the stage for next week

1:08:09kknewkles I noticed that you tend to mostly skip over questions past the first question mark. Is it because you just parse that way or the rest tends to be not much interesting?

1:09:03garlandobloom For things like the projectiles, are we going to extend their bounding boxes in the Z axis so they will always hit enemies that are below them? Or are we going to handle that in screen space somehow?
