I believe this is referencing a meme on the primeagen's standup podcast, where Casey is referred to as legendary while he feels undeserving of this title.
Titles aside, his talk is really insightful and it is super interesting to do a deep dive on these old computer/programming topics as the modern concepts were being discovered
Hah, I wasn't aware of that. I was sort of referring to what seems to be not such a meme that jblow is always introduced like that. It just seems weird, even if true...
Yeah Ive been meaning to watch that talk - I love listening to pretty much anything Casey says/does. He's extremely thoughtful and fair.
Are they? Casey programmed the walk monster for Jon's game, a brute force tester to make sure you could always walk both ways and never get stuck, instead of building the walking system using a nav mesh. There was one place you could walk where you weren't supposed to, despite the walk monster, that would have been obvious if it was a nav mesh.
Doesn't mean you can't learn a lot from the attempt. Technical craftsmanship and project management skill are two completely separate skills. Definitely don't learn project management from Casey.
Sure, but the biggest reason to direct anybody to these videos is that they should actually make that video game they want to make, not just think about it - and so the fact that Handmade Hero just trails off and doesn't end up producing a finished video game is a problem.
The craftsmanship is dubious. I think it's a problem that people assume Casey knows what he's doing when so often he's like "We're doing it live" and Casey's hand coded solution is pretty bad whereas the thing which came in the box is very good. Casey understands Casey's version, and that's an upside if you are Casey but you are not. If the result was a finished game then hey, whatever, the game was finished and that matters. But that part didn't happen either, so then it's just like watching Tsoding or something.
At some point I stopped caring about Handmade Hero because he just never got out of the global illumination rabbit hole. He should have followed that as a side quest, behind a feature flag. Maybe one week for progress on the game, one week for rendering experiments. He didn't seem to make much progress, and it just fizzled out as he ran out of steam. Finishing should have been a bit higher on the priority list. It was just not setting a good example from a project or self management perspective.
Well Billy Basso was hugely inspired by the Handmade Hero series and went on to make the critically acclaimed Animal Well because of it. That's enough of a win for that series in my eyes.
John Carmack is a legendary game programmer. If I can identify a superior algorithmic approach to something in Doom, does that disqualify Carmack's credentials?
First I think I'd want to see you identify a superior algorithm known when Doom shipped and then we can have that discussion about who's credentials should be disqualified.
I never made claims to be any kind of game programmer, but sure.
Fine, as I recall, Doom data assets are searched linearly whenever they need to pull new data. So if you switch to the chainsaw, and need to rev, the game does a linear scan of all graphics, maps, and sounds looking for the vroom noise.
There are many different data structures that could perform this lookup faster. These have been known since the earliest days of computing.
Does it matter? No. Engineering is all about trade-offs. A linear scan was obviously fast enough and simple to implement.
Similarly, if walk monster manually trolls the map, that does not say anything about Casey in isolation. I believe all of Blow's games use a custom game engine, so unless a nav mesh system was already implemented, that was going to take additional work. The walk monster may have been better bang-for-buck.
(to be clear, I'm a big fan of Casey)
