HappyHippo posted:I've been considering a lite RTS. I don't think I'd base it off this though - it isn't grid based and there's no pathfinding at all. In that case do you mind if I steal the art style and heavily base some mechanics off of it? I've been wanting to do a simple RTS for a while now but was having trouble finding a good starting place/goal.

HappyHippo posted:Thanks guys This one might never actually finish:  I'm running it in a VM, it's going about 1 frame per 4 seconds right now. There's so many bases that I can't count them any more, but it was about 50 for each side before it got too crowded. One thing to help prevent this might be being pickier about where bases can be built (e.g. not on top of each other), but you're not doing collision checks right now which I assume would be problematic.

You could do something like 'a base can't be built within d distance of another base' and just brute-force the list of bases every time a new one gets built.

From Earth posted:Up next: Shadow-casting for non-floor-to-ceiling objects (e.g., characters and low walls), diffuse lighting, and reflections if I feel up to it. Is the basic idea for non-floor-to-ceiling objects that they reduce light by some percentage depending on how big they are? And you should totally do reflection, I don't think it will be very hard, and it will really push the realism through the roof. Does everything in your world have material types?

gold brick posted:Don't know if you saw this, but Eric Lippert (from the C# compiler team) had a series of posts on this a while back. The code is in C#, but he spends a good deal of time discussing how he went about solving the problem. I went into this without reading up on existing algorithms, because I wanted to figure it out on my own. Scrolling through the article, it seems I do at least one thing the same (dividing the full 360 degree range into eight sections, and solving each independently), but there are some differences. Once I've got all features in, I might do a write-up of how my algorithm works. taqueso posted:Is the basic idea for non-floor-to-ceiling objects that they reduce light by some percentage depending on how big they are? Not quite. Like I said, I might do a full write-up in the future, but the basic idea is that I'll project the shadow of the object onto the 256*64 image that I use to determine the light color for a given set of angles. That way, all points behind the object will sample their light color from the now-shaded area, which will make them darker. The cool thing is that it even allows for neat effects like colored glass, since that'd be as easy as slapping a blue "shade" onto the light map instead of a black one. quote:And you should totally do reflection, I don't think it will be very hard, and it will really push the realism through the roof. Does everything in your world have material types? Not yet, I'll add that once I add diffusion. I hope reflection will be somewhat doable, I haven't really given it much thought yet.

There's no way I can release this since I don't have the Drinkify creators' permission, but I wanted to play with writing a basic Spotify app: Predictably, the Spotify apps API is awesome to work with and a lot of fun. Since Drinkify doesn't have an API, and their website doesn't support CORS, I had to whip up a JSON proxy. Sinatra + Heroku is awesome for doing stuff like that; I had a solution up and running in like 30 minutes

I spent the last couple of months building an open-frame laser bed for a client, and today I got the OK to use some screenshots as a portfolio piece. I can't show any actual test data however, so everything in the image below comes from a software simulation of the hardware system that I use to test the control program. The hardware setup consists of a Class IV source laser that shoots a beam into a test sample. The test sample is temperature controlled and spits out another laser beam at a different wavelength. There's a thermal power detector head that absorbs the output laser beam and figures out how strong it is by measuring a thermal gradient across a cooling structure, and finally there's a folded-grating spectrometer to monitor all the beam wavelengths. All the hardware components plug into a master control program for easy operator use. If you've ever worked with vendor hardware interop you know that 90% of all hardware drivers could be pasted wholesale into the Coding Horrors thread, so I spent a lot of time hiding all the terrible interop structure inside of a set of wrapper objects an just exposing a minimal set of properties/methods that let you operate the device as if it was just another C# object. Each hardware device has to run on its own thread so they don't interfere with each other's operation, so I also made a custom databinding system to connect the device wrapper properties to the UI thread that handles all the cross-threading bullshit internally. I wish I could show a picture of the hardware setup in operation but that'll take a lot more finagling since we have to clear images through various NDAs, IP lawyers, and ITAR regulations. The laser beams are all out of the visible range but if you turn off the lights and take a picture with a digital camera scattered light from the beams show up as a kind of electric purple color. With the silhouettes of all the control wires and cooling lines and the dark room background it just looks like some kind of demonic hell device and is all  as gently caress.

I'm a 2nd ed AD&D DM, and I was writing up the details for a location, when I looked at the treasure listing for ogres. Treasure type: M(Q, B, S). What the hell? Is that a lot, a little? Instead of opening up a book and going through the tables and lists to see what's what, I wrote my own treasure generator 100% based off the 2e DMG. Every chart is in there, and I went even deeper to the items themselves. Some items have random stats and random powers and random alignments and such that the tables themselves don't describe, and most generators skip over. Mine does it all easily from a console. The only thing I've yet to add is the chance of a sword being intelligent, and all the things that entails.  This was simple to make, just really tedious as it was just putting in d20 and d100 chart one after another, linking them together, and poring through every item description to make sure I got all the rolls right. Also, I have no idea how to make a UI with C++, so I've always just made console command stuff.

Does it have to be awesome super-serious stuff? I spent a little time learning javascript (coming from a C/C++ background) and got this far in a couple days learning canvas. Also, I have hooked up basic mouse capture. Part of me wants to keep going and try to turn it into a simple game, to force me to keep learning. Another part wants to retreat crying because JS is weird and scary (typeof doesn't even do what it's supposed to half the time). A third part is thinking I'm posing this in the wrong thread. Ah well, CHECKERBOARDS!

I'll check QT out later, thanks! Though I don't think this kind of application (command ->output) really needs much of a UI, a D&D forum I posted it on doesn't care a bit, except for "Will this be released with a UI?" Edit: Nice checkerboard, good practice for a new language. Now add choice of colors!

 Been working on a little RPG. Right now, all I have is a rough battle system. HP and AT (like Final Fantasy!) bars work and animate well. The character sprites animate to cast magic, attack, or use items. The open space at the top middle is where the magic and item menus open into after you click them. I need to get spells and items working. From there, I gotta make it so enemies attack you when their AT gets full. From there, I gotta code in stuff actually dying. I'm not artistic, at all, and I'm a novice programmer (1 year of experience in an AP class in high school, and half a semester in college), so I'm really proud of this project. It's also my first time using Python.

Keep working on it man! Subspace is probably one of my all time favorite games (DSB4Life) and it just keeps slowly dying....  I mean it is like 15 years old now I guess though.

Thanks, right now it's really early in the development stages and those are mockups so it will probably be dramatically different before we are done. It will all be web based though and serve about 30 stores.

Also, you may want to be more deliberate in your use of color. For example, red indicates both void and pay, which are opposite actions, right? Blue means options and list products? The lines in the payment area seem to blur/smunge together.
