I've often had times just getting used to basic geometry, because I'm an idiot and it's hard to find a good reference. Is it more about the computational grittiness, or does it go over the theory / math of arbitrary intersecting polygons as well?

It'll tell you how to get far enough along with that to work out contact points. For concave shapes it basically recommends chopping the object into convex shapes then testing the same way. Anything more complex than this and you are heading into computational geometry territory which gets really complicated really quickly. The main strategy for detecting the collisions of static items is done through a separating axis test. If you take apart Monogame or SharpDX, you'll see a lot of references to that book. Also don't feel bad, I'm still learning this stuff and it still makes my head hurt.

I second the recommendation for Real-Time Collision Detection as a good book to own if occasionally you need to know how to intersect things with other things. Other than papers newer than the actual book it covers pretty much anything on the subject you could want. I'd also recommend looking at Real Time Rendering's collision algorithm matrix but a lot of the entries reference things in RTR or RTCD, and a lot of the paper links are stale. Still, it should at least help you find the right pdf elsewhere.

Three points: I was getting hella one-shotted by medium opponents. But I did see them futilely firing shots off the edge of the screen that didn't appear to be wrapping around to the other side -- so maybe there's a problem either with shots wrapping, or with AI calculation of such attempts. And a minus button on the buying screen would be nice.

Couple of weeks ago I started making planets using gimp. I decided that making planets was too much work, so I went procedural and here is the result: I finally managed to get atmospheric scattering right. In fact I should make that into a libgdx library and finally answer my own stackoverflow question from a year ago: http://gamedev.stackexchange.com/questions/50373/atmospheric-scattering-sky-from-space-artifacts The problem was moving either planet or camera. The original shaders make the assumption that the planet is at 0, 0, 0. When you adjust camera position or planet position, you just need to ensure that it holds true and make other calculations account for it. Right now I need to focus on gameplay rather than fancy stuff, but in future I'll also add support for gas giants. Right now it only supports basic earth-like planets with various colors.

Thanks KICK BAMA KICK posted:It is real fun. Three points: Heh, the thing that makes them medium is that they occasionally miss  . Hard never misses unless an obstacle gets in the way, cruel is like hard but picks the highest angle shot possible to reduce the chances of hitting a mountain. If no accurate shot is possible (usually because a cliff in the way, or due to being downwind when the wind is strong) the AI fires randomly. It looks weird but I did it to ensure that the game can end - if I applied some sort of strategy like "shoot to get as close as possible" they could get stuck in a loop of two AIs missing each other forever. Did you mean you want to sell items? I hadn't thought of that but I kinda like that you have to make a choice without being able to go back on it. Maide posted:I've ran it with 10 max difficulty AIs fighting each other with crazy settings for a few hours now, and it's great fun to watch. Player 2 is overpowered, from the simulations I've ran. Yeah it can be fun to just watch them, especially when the power level is high. I can't think of a reason why any player would be more powerful from the beginning of a game, but once a player gets the lead they tend to keep it since they have more money to buy weapons/defences.

 Lame python shell screenshot, but I wrote a script that scrapes a very specific type of wikipedia page (Billboard Hot 100 year overview pages). And it works! Now I just need to turn these data chunks into SQL entries, which will have to wait until way late tomorrow because I can't possibly work on this at work anymore. I work as a security guard, and the work computer can handle the Python shell, but cannot handle running an SQL server alongside all the other things. edit: forgot the obligatory apology to the gods for my filthy mortality, you guys do amazing things here Also this is my first project in Python, the code can be found here.

I'm still investigating options for database stuff, and I'd like to clarify that I wasn't going to run the SQL server on my work's computer and connect to it remotely or anything. Rather, I meant simply running it so I could send local instructions via my script. Somebody elsewhere suggested using Amazon AWS/DynamoDB for this whole project, which I'm still looking into. I have almost zero ideas of where to start with regards to databases, so yay learning experiences. Thanks for the suggestions, though!

 Click for bigger It's a browser "game" inspired by incremental clicker/idle games. Basically you sit there and let it run and your representative in the world goes out to harvest stuff for you. Of course, to get the rarer items, you'll need to craft items which boost your stats. These items use up items in your inventory, and you can only boost your stats so far in one direction in the game. HOWEVER, you can "soft reset" which resets your stats and clears your inventory but keeps your log of items/creatures you've discovered, so you can refocus your character on the next run to be better at getting drops from combat, rather than say, foraging. Once you collect every item, fight every monster, and get all the flavour text you get the final achievement and are free to depart this realm. I know its dumb but there are more boring ways to learn JavaScript I guess!!!!

Sergeant Baboon posted:This sounds like fun, do you have it online somewhere that we can play it? Hm I was hoping to develop this more first as like I say there's no interaction yet but to be honest if I can get critiques on my JS that would be awesome. It's using bootstrap and jQuery. The content is generated from text files and inserted dynamically, so the items can be added really quickly without having to hard code anything into the template or write a large object in code. Here!. Please note that it is very early days and right now there is nothing you can do but sit and watch your collection grow. There is no interaction yet. Try editing CWind.Player.perception or similar between 1 and 10 and I'll increase your drop rate for certain items

I wish I could give useful critique, but a quick glance at the code is enough to show that you know JavaScript a hell of a lot better than I do. Sorry! I've been wishing for a game that had the same idling mechanic as Cookie Clicker but is actually, y'know, fun, and I like the style of this game already. I'm looking forward to future updates!

My local library has a new book display for each of their collections, like non-fiction, adult fiction, dvds etc. New books go on display for a week, and you can place a hold on them before they go out on the shelves. I always like to check out the new books, but sometimes I can't make it in that week or someone's hidden the good ones when I can get there. Anyway I've been working on a way to get a list of these new books from the library website. As it happens, they recently changed their catalog and website software and now there's an RSS feed of all new items, so I wrote a web app to extract info from the feed, pull some extra info and also to help weed out some of the stuff I'm not interested in, like childrens books or foreign language writing. This is the first project I've done that's worth posting here, and I've been using it to learn git and to test out appharbor - I spent a lot of time working out a good enough way to generate my database objects inside my apps sql instance, because getting the actual error info was like pulling teeth. My scheme for taking each item in the rss feed and getting extra info from the library site is the biggest bottleneck at the moment, if anyone feels like taking a look at my code. Source here, in action here. Anyway, screenshot!

Here's a little game I'm working on to teach myself more about Python. It's sort of designed around half-memories of a game I played when I was wee called SimCinema Deluxe where you hired actors, wrote a little plot summary and then bought advertisements to promote your film. My version's a bit more fleshed out in gameplay mechanics, though most of them aren't fully realised yet because I've not done the filming/release part yet. The only thing I've been completely stumped on so far is changing the font of the menubar. Still, I'm pretty pleased with it as a first 'major' project.

Careful Drums posted:This is cool little project! I've been looking at .NET hosting, how is appharbor? Do they provide a db on the free service? Thanks! I'm using their free sql server plan which gives 20mb of storage and sql management access, but there are other db options like mysql etc, and there are other add-ons too like memcache, mailgun, and stuff for full text search among others. Each add-on has different service levels although not all have a free option. I've never built a hosted app before, and working out how to get meaningful errors out of the sql server was a bit of a pain, but I really like how it works with github to update itself with your latest commits.

Pollyanna posted:I think there was a library called amulet that handled curses for Rust. Yeah, it was one of the ones I tried in trying to find one that compiled, but it was last updated 7 months ago so it was too far from being compilable. The one I used was like a week old and still didn't compile out of the box (and actually after me updating it yesterday the examples don't compile today since it depends on the nightly build for some things). Basically, it's sorta a nightmare and I'm sad they got rid of rustpkg, but I guess it just wasn't working for them.

It's something that I am still tinkering with, but it is not intended to be read at first. To take an example from another game, Fez features a made-up ingame alphabet which is initially unintelligible. Eventually you find a key for decoding it and then you can laboriously decode inane messages around the world. I liked that idea, but I didn't like dragging the player through decoding after they've had the "aha!" moment, so I wanted to try to come up with a weird font that is similar enough to english to be legible once you recognize what it is. I'm not at all married to the idea, so I might still take it in a different direction.

The fact that it's close enough to our alphabet but still illegible makes it more annoying to decode, not less.

I'd agree with Dish that it'd be better to just make up your own symbols and have them be totally foreign though, so long as you can be creative enough that the symbols are clearly distinct. Also if you're gonna go down that route, make sure its only fun secrets and easter eggs and gags and stuff, not major important game clues. If you decode something you didn't have to for a fun joke or a secret, that's cool, but if you have to only to get "go to X" or "drink more ovaltine" its just frustrating. Probably assume most gamers won't even try. Its unbelievable how lazy gamers are now.  Back in my day we had to...
