Yeah. I've relatively little experience with networking so whatever you'd recommend, if TCP is a bad choice. I've only ever done a little bit of TCP/IP and RPC stuff.

Nah TCP is great for that.

[InfiniteStateMachine]

Yeah TCP would be my only choice between game and tools. Who wants to deal with a lost packet when everything is local (ok I'm assuming everything is local :X)


also libuv is apparently the backend for nodejs so it's certainly been tested.

For some reason it's super difficult to find a full up-to-date list of not only what game controllers SDL 2 has built-in support/profiles for but also on what systems they work. I'm trying to find info on the Steam controller. There's a recent commit adding support for it "on Linux and iOS", but I don't know about Windows or Mac tho it seems weird iOS would be added before them. Anybody know where to find this sort of info?

[qMopey]

I don't have info, but I can say that one dude Sam doesn't he work at Valve? Pretty sure those guys will pump out support for their Steam-ey things into SDL very consistently. But unfortunately I don't know specifics. I'd suggest to just try it out and see what you can get.

Just to clarify. Every tool you build/use has to either choose TCP or UDP to interface networking, which is a part of the operating system. In practice there is not really that much you can do to affect internet traffic/quality of service. In short, if you want to ensure that your sent packet successfully arrives, use TCP (but it introduces more overhead than UDP). If you don't care about occasional packet loss that much, use UDP.

Ah, thanks for clearing that up.

IDK how actively he's involved in SDL atm but icculus aka Ryan Gordon is pretty accessible via mail, could just ask him.
Anyways I know as much as that the Steam controller partly registers as a mouse device. Pretty much any controller that you can think of should be halfway supported on any system afaik.

On the TCP/UDP issue let me add that UDP is usually what you use for game protocols - even if you need/want reliability for some messages, Glenn Fiedler's articles (gafferongames) give good insight on why and how.
But for tools you very certainly fit the exact requirements that TCP has been built for.

[oahda]

Yeah, I'm definitely taking the slight overhead over lost packages for something like that. Will see if I dare mail this person, thanks!

As for the steam controller, there is no support for it in sdl as it looks like a keyboard and mouse. You have to use steamworks for that.

My flatmate had email convos with him before he used to be pretty cool to talk to I think.

The Steam controller appears as a keyboard and mouse to your computer? Seems weird, but I get why it would be that way. I'll be able to experiment with that at least, since I ordered two steam controllers a while ago.

For those interested in networking protocols specifically for the world of game development this is a great website

It's because of the trackpads mostly I guess. They're supposed to model mouse like control after all.
It being locked to steamworks is pretty disappointing though.

How would one go about determining the technical specs for one's game? Like, my game is a pretty simplistic puzzle game running on a high-end gaming laptop, but I'm pretty sure most people don't need the specs I have.

[qMopey]

Well the way I'm doing it is to track my memory usage, and place hard-limits, from project conception. This can be super hard to do with pre-made engines, but for my own code there's a hard 2GB RAM limit and that number can be adjusted. There's an LRU cache for swapping in and out assets in an async streaming manner. Similar idea for GPU memory.

Specs for min CPU and net bandwidth are probably much easier to come up with. Just set something you recommend the player have to enjoy the game. Same idea for power of the GPU. I myself actually bought some low end machines with really cheap hardware, and can test my stuff on there whenever needed.

Is it enough to slap on a mutex to make logging threadsafe?

Yeah should be.

[oahda]

Seems like it did the trick.

Without mutex:



With one:

Ok, I ported the monogame math API (matrices, quaternions, vectors) to my engine. But, I was wondering, what's the best way to represent the object position/rotation/scale (that works for both 2D and 3D)?

Would this suffice?

Code:

struct ctransform {
    cvector3 pos;
    cvector3 scale;
    cquaternion rotation;
};

Then, in the rendering, I would make 3 matrices from those and multiply the end result.

in unity when i'm using licecap to get gifs of my game, when my cursor is hidden, it's still showing up on the gif in the end. it is a custom mouse if that makes any difference.
