Chandler Carruth's CPPCon talk [0] this year was also great (surprisingly, as I had a fairly low opinion of most of the others). It wasn't better than Mike Acton's [1], but I suspect that it was more actionable for most devs.

That's a pretty ridiculous use case. I'd think if you wanted to make a change this drastic, having to reload the game wouldn't be a huge deal. I mean, you'd want to make sure everything up to the point you were at still

The big downside with this is that you can't use function pointers or addresses to static memory (which means need to be careful with e.g. string literals). This is a pretty heavy restriction, and is too much of a limitation for a lot

This isn't really a good comparison at all. Game developers make around 10-20k less than a typical software engineers salary. That's still far more than a lot of lines of work. Maybe what you're saying is true if you'r

I used to take Ritalin, and it had serious negative effects on me after a while. When it would wear off I would become depressed and unable to do anything until the next morning when I would take it again. Since then I've been diagnose

> That is your opinion Well, it's not really an opinion though. Unless everybody had a perfectly equal standard of living (which sounds vaguely Harrison Bergeron-esque) there will always be a lower class, even if they have a rathe

That's a fairly compelling argument, but I definitely have had times where I wished for a numpad on my Macbook, mainly so that I could play games that required them (I went through a few months where I played through several traditiona

Really? You don't think they'd want to be able to show their friends? Mobile might be an artificial use case or a premature optimization, but it is solved with his choice of JS.

If you're going to move to a static language, I'd recommend Go over Java or Scala. Especially if you like duck typing (it has a static flavor of duck typing). I haven't used it for anything nontrivial (you can pry C from my c

My understanding is that LuaJIT isn't really under active development anymore. It does seem like it would be hard to add the 5.3 features to LuaJIT without compromising on efficiency, but given how clever Mike Pall is, I'd suspect

by yoklov 12y ago
My guess is that this would still be a bottleneck in practice. LuaJit has a similar feature, and Mike Pall has said several times that if you care about performance, you're almost certainly better off using 100% Lua, because calling in

This makes a lot of sense, and makes me appreciate the choice more (although my gut feeling was that it was a good idea).

Well, it's harder to grep, for one (although far from impossible).

Examples != a game, and given that scenario, I would recommend trying to make a game at this point, but I'll leave it be. And that's fair. I didn't think this way until after working in industry for a while, and my code from

Honestly, it sounds like you are over-engineering this... Forgive me if I'm wrong, but the impression I'm getting here is that you're writing the engine before the game. Never do this. Just don't. What you should do inst

I'm a game developer and I don't use inheritance a lot, and when I do use it it's almost never for virtual dispatch. (I wouldn't mind it being added to Rust, but I don't expect I would use it). Anyway, if you'r

Part of it would be done on a shader (mainly the visual portion, like the glowing and whatnot) but I think most of the effect would need to be done on the CPU. You might be able to make it work with clever usage of geometry or tesselation s

The macro usage might look daunting but most of it is pretty typical for libraries without platform dependancies (lots of compiler dependant config and shims for missing libraries). Look for "BEGIN PUBLIC API" for the stuff you&#x

Even indie games can benefit a lot from components, and a basic component-entity system is very easy to implement. Make component and entity classes, give the entities a list of components, put the update method in the component, and put mo

Caveat: I'm not a rendering engineer (though I do work in game development), so my knowledge might be a bit out of date or imperfect. It's very clever, and leads to pixel-perfect shadows. the other main technique used to do real t

`-ffast-math` is a double-edged sword. It can frequently optimize away stuff like NaN checks and the like, breaking code that uses NaN as a missing value. This, specifically, has bitten me before, but there are certainly other areas that it

Probably because until relatively recently, MS has not open sourced very much or any software, whereas Apple has a number of notable open source projects (LLVM/Clang, Webkit/JSCore, ...). OS X is also build on open source software

I think his point was that the standard (even C11) leaves a great deal of implementation-specific behavior. C++11 has the same problem (as it has the same implementation specific behavior as C), but the standard library allows you to avoid

The biggest downside of display: table and friends is performance. Changing any CSS or DOM properties will basically cause a full page (!) relayout and repaint on a lot of browsers (especially mobile safari).
