Since you don't have a Procfile, your app is probably running on webrick instead of thin on cedar, even though you have it in your gemfile. See: http://devcenter.heroku.com/articles/procfile You want something like web: bundle exec thin start -p $PORT

ImDifferent posted:How does the multi-threading figure in? I take it you're not creating a thread per connection - otherwise you wouldn't be that much better off than just using blocking sockets. There are a fixed number of threads (probably the number of cores or twice that number) and connections are assigned randomly to a thread. This is completely going to bottleneck on the network connection, even if you ran it on one CPU, of course.

In the spirit of servers, I started working on adding multiplayer support to my game. My little server.  My 2 little test players (me on 2 different machines). I've never done multiplayer work before and now that I'm into it, I feel like this should've been one of the first things I did. A lot of the work is going to have to be offloaded to the server, so I'm wondering if I should have single player also launch a small local server so I'm not duplicating code between client and server. When the player launches in single player, they would just the only person on their server. When they get to the multiplayer stage of the game, the server can start allowing connections in. I don't know. Either way, it's fun to program.

100% yes to having single-player be local-only multiplayer. It's so annoying in a game to start single-player and then go "sorry friend, you can't join me because I didn't tick the 'multiplayer' checkbox when I started this game last week".

The concept of how I want to make multiplayer in my game also leans me in that direction. When the player gets to the 'multiplayer' stage (after they've terraformed the asteroid they're on, have built a successful base that can defend itself and have a good air seal), they can create 'portals'. Each portal can dial into another server and will allow people to come into your personal world while you're playing (if you keep it turned on). So ya, the single-player = local-multiplayer idea is more appealing. I just wish I would've done that from the beginning instead of building most of the game out first and then switching to it.

In the third shot you can see the five touches splayed out, with distances and angles drawn in. These shots have all the bells & whistles turned on - normally it only shows which controllers are currently active for the patch you're playing.More info soon - I'm sooooo close to releasing it. Just wanted to post in this thread while it's still 'in progress.'

I live in Los Angeles without a car, so I'm almost totally reliant on the public transit system. Finding Metro-accessible things to do, doctors, restaurants, etc. on sites like Yelp, Google Maps, FourSquare, etc. was a horrible crapshoot, so I made an app which will do it for me! yumMetro   Twitter Bootstrap kicks serious rear end, especially since I'm an awful designer but hate to use ugly sites. I would have loved to keep this closed-source and try to (seriously) monetize it but I need to be able to show off the source to prospective employers. It's actually still pretty inconvenient to use (search for 'butts' near every blue line station? good luck with that) but I have some ideas to work on to make it much more awesome . In fact, right now, you can pretty much do everything on Yelp! already (search for 'butts' near 'wilshire / western station, CA')

This is what I've managed so far: https://www.youtube.com/watch?v=PNqrahhTgyc I'm fairly new to programming in general, so it's been tough but enjoyable! I'm trying to sort out the collision detection right now, you can see from that video that it's not working so great. Each time the character passes in between two tiles it levitates up by one pixel or so which is pretty annoying. I feel I need to get this movement/collision stuff working properly before I can move on to more interesting parts of the game. Stiggs fucked around with this message at 00:13 on Dec 6, 2011 |

I feel I need to get this movement/collision stuff working properly before I can move on to more interesting parts of the game. Collision detection is always tough. Just eyeballing it I'd guess that you are checking to see if the character collides with a solid box below, and if so you're moving the character up one pixel. Then when the character transitions between two solid boxes you're getting two collision hits - one from the left box and one from the right box - in one frame and moving the character up twice. Up twice due to collisions, down once due to gravity and you get hovering or bouncing. FYI, we have a game programming thread you might want to check out. There are lots of people there who can help out with this kind of thing.

If you're going to add multiplayer for serious thing, do it properly and not like Terraria's horrible poo poo. Vulnerable to denial of service and running every core 100% plus mem leaking from a single telnet client, trusting client for everything including attributes like "can this thing explode" = expected results on every public server. Oh, and the (windows only binary)

Biowarfare posted:If you're going to add multiplayer for serious thing, do it properly and not like Terraria's horrible poo poo. The server is written in generic c# and MonoGame, so I can build for Windows/Linux/Mac. It will not require a GPU at all and almost all of the game update work will be done on the server. The client will only be a graphical representation of the status of the server. Even when you're in single player, the server will be launched locally but it'll allow only you to join it. Anyway, I don't want to keep hijacking this thread so here's a screenshot of the calm before the storm:  The server now has all of the in-game objects and managers built in. It doesn't throw any errors (although there are lots of warnings), so now I need to integrate all of the manager's update() methods, form the packets for each individual player and start sending them out.

On the upside it isn't obfuscated and as far as I can tell the devs give no real fucks about the reverse-engineered dedicated server mods. On the downside the code is so bad that both teams creating dedicated server mods are considering quitting.

Yeah, yeah, babby's first raytracer, but I wrote the core in python and then turned the matrix math into a C module (making it about 10x faster), so it's a learning experience for multiple reasons.

What sort of render times are you getting for the teapot scene? If you're brute-forcing the intersection tests (i.e. testing each ray for intersection with each polygon), you should look into bounding volume hierarchies or k-d trees. They make a huge difference in scenes with more than a few polygons/primitives.

It's using a sphere tree. The teapot takes about 15 minutes, most of which is taken up in sphere-ray intersections, because that part's still in python.

Finally got the k-d tree working yesterday, so I implemented triangle meshes today. Total render time, about 20 seconds (with 8 cores) with the k-d tree on and (judging by how slow it is when I run it) about 2 hours with them off. It also uses an embedded Lua interpreter with bindings to my scene objects instead of parsing scene files so I can do things like generate geometry on the fly (see: the ring of spheres).
