Crossposting from the Making Games thread: https://www.youtube.com/watch?v=sNT6mNhQbB0 Video of skeleton animation (via Spine) working in my engine, complete with aiming. It's really easy to modify the skeleton at runtime, which is going to lead to some fun effects. I can actually start making enemies / anything else that's supposed to be animated, since I'm awful at traditional sprite animation. Not sure what I'll work on next, maybe just some general tilesets and level design.

I just pushed out another release of BeagleSNES. Among other things, it now supports: ... two gamepads for the BeagleBone Black. This might not seem like a big deal, but there are actually a family of community kernel patches that I needed to apply in order to support recovery from voltage noise from external hubs ("babble"), USB device discovery and enumeration, and hot-plugging. It wouldn't be a new release without a video, so here you go: https://www.youtube.com/watch?v=RMdrskg66bQ I also took a gamble and started BeagleSNES as the init process for the kernel. That shaves about 8-9 seconds off of the system boot time, but it also makes the system completely dependent on that process. The init process never terminates, so if BeagleSNES quits, the kernel panics. But hey... it boots fast, so that's good, right? Lumpy was kind enough to assist me by whipping up a scrollbar thumb that I now use in the game selection menu. Now you can throw as many titles in there as you like.

It's annoying to create an entry for every game, especially since I don't care about the date/genre/ect. Those microSD cards are slow, slow, slow, so I avoid doing file system scans like that. What I should really be doing is making it even worse: make the end users place the ROMs and box images into a cramfs loop file and then mount the thing to pull everything out. That way, a scan like that will go much faster, since you're looking through the index of the file in memory, rather than hitting the disk over and over. Plus, you're pulling far less data off of the disk because it is compressed. But, I think that what I'll eventually end up doing is make a desktop app that builds the games.cfg and an archive file like that for you. Then you just drop the generated files into your system and be done with it. quote:Otherwise it's been working fine for me, and the documentation on your site is incredibly detailed. Thanks! The documentation is about a version and a half behind at the moment, so I need to get it up to date. It is my hope that my docs will help out some other developers that are working on single-purpose multimedia apps like this. There isn't a whole lot of easy-to-understand docs out there for these platforms, and not everyone is up to picking through code to figure out what is going on, so I do what I can to help other devs out.

I've been learning Javascript and Canvas by doing little graphic effects apps. The one I'm currently working on attempts to simulate the glittering back of my Nexus 4 phone. What I'm doing is dividing the canvas up into "facets" with a random vector for each facet acting as a surface normal of sorts. I then use the mouse as a light emitter and figure out how much "mouse light" is reflecting off each facet. It looks pretty neat right now but has a defect which I'm sure is due to the naive way in which I'm calculating the light direction to each facet. I'm pretty sure I need to modify the vector subtraction to take into account which side of the facet the light is on. You can see it moving here.

I know crap-all about JS so I've no doubt cocked up in a number of ways but the main reason you were getting the weird anisotropic comet-ish shape was because the randomized facet normal components used range(0,1) rather than range(-1,1). Edit: Also did a version were the facets are a brushed metal at random orientation by adding a ward brdf and randomizing the direction of maximum anisotropy rather than the surface normal, as I figured that (more actually microfacetty) model would be more like the real phone thingamabob than the randomly angled lambertians from before. The lack of dynamic range actually makes it look worse, though. Oh well. Xerophyte fucked around with this message at 22:35 on Jun 8, 2013 |

Ah nuts! I didn't even consider that I was using only a quarter of the Cartesian space when calculating the faux normals. I like that you turned it into a three dimensional light; that opens it up to some neat effects and simulating different light conditions.

I don't really know if this is the right place for this, but hey why not. I spent the last day or so spending some time messing around with Flask and wanted to do some sort of chrome plugin as well, so I made a youtube extension that shows if a song is available on rdio or spotify (and I might add more similar services later).  Would anyone be interested in using this? Is it against anyone's terms of service?

I've been thinking it would be cool to set up a collection of D3.js visualizations on my website, and I've just put up the first one. The goal is smaller, more focused charts that I can do more of, for like a gallery. Click through for the animated/interactive version & source code, but here's a screenshot for the thread. I'm pretty happy with it overall but I'm ready to move on to the next one. I will say that 1) I don't really like SVG 2) I REALLY don't like working with SVG text 3) D3.js is very nice for this kind of project. Link

I thought the same thing, but I remember that sometimes coordinates for images have their origin at the top left, making the positive for both values down and to the right. But 99 out of 100 people would say it's backwards and could hurt their experience with the interface due to their intuition.hendersa posted:I received a mail earlier this morning from a fellow over at Texas Instruments.

But 99 out of 100 people would say it's backwards and could hurt their experience with the interface due to their intuition. The problem isn't which direction the positives are in, it's that the angle still goes counter-clockwise, when it should be going clockwise. The vertical value of 90º should be 1. Whether that 1 is at the top or bottom is up to you, but that's where the 90º should be, for example.

Just like how all the angle values are reversed because in SVG angles increment clockwise, again opposite conventional unit circles. Fixed now

What I'm working on isn't nearly as interesting as what other people post in here, but after recently finishing my semester, I decided to get node.js working and get a bot going to monitor a steam chat I'm a part of and collect a range of stats. After much messing around I got the bot to a stable point, and started collecting data proper, but I figured it'd be a waste to just toss all that old data I got, so I then decided to build a front end to visualize it. I'm not a big fan of the chart plugin I'm using and normally I'd write my own using PHP and GDLibrary, but I figured if I'm already learning something new, I might as well continue learning. The end result was the following:  Members of the chat can also use !mystats in chat or message the bot directly, and it'll respond with a message containing a link to their stats once I put things live proper. For now the bot directs members to something similar to this, and the front page gives overall stats for the group. I don't really like highcharts, though I think it's more because this is the first time I've used it, and JavaScript isn't really my strong point so it felt really hacky to get things displayed,it was the easiest to get running quickly though, so I stuck with it. Though honestly, I just love stats and being able to visualize them and this project has just been a terrible enabler for my addiction.

I'm working on a data logger / data viewer platform. I made a C# desktop app that makes it easy to configure an XML doc full of OPC servers and the loggable tags in each one. The XML document is fed into a windows service that I wrote which talks to the OPC servers (which pull tags from PLC systems) over COM and logs values to a SQL Server. You can view all of the data in the SQL database with a little PHP web application. Still need to work on securing and documenting all of it, but the basic features are there. It's really basic but it beats spending $16,000 for the brand name solutions.

Now, I realize that this probably doesn't look very exciting at first glance: ... but, there is actually an interesting story behind it. That is the BeagleBone Black running Android. The interesting part is that I've gotten the hardware to run Android 4.2.2 (Jellybean) with a 3.8.13 Linux kernel. Android has just became available for the BBB maybe a week ago via Rowboat, but it uses the 3.2 Linux kernel. For those that don't know, an Android kernel is actually just a Linux kernel with another 25k or so of Android-specific stuff built into it: out of memory manager, Binder IPC, etc. So, if you build in the extra bits, then whatever Linux device drivers are available in that kernel are available to an Android OS based upon the kernel. You can even build the extra Android functionality into your Linux kernel and still run it just fine on your Linux system. You'll have a few extra things hanging around, like a "/dev/binder" in your file system, but it will work without issue. OS hipsters can then brag that they run an Android kernel on their desktop. The 3.8 Linux kernel tree went in a "different direction" than the "stable" 3.2 kernel and added a lot of new features and support for BBB hardware. It is also really broken (but getting better fairly quickly). It took a lot of time and swearing, but I managed to resolve the toolchain/kernel/patches/build script problems and got Android up and running under a (patched all to hell) 3.8 kernel. Probably the big selling point is that my 3.8 version uses all of the HDMI driver support in the 3.8 kernel, meaning that you can now hook your Android BBB up to your 60" HDMI TV and use it to display Android with the audio coming out of the TV. The 3.2-based Android required a "cape" add-on board to be plugged into the BBB to drive an external LCD display and provide audio hardware. With my version, you no longer need the cape board (unless you want a touchscreen display). If you feel that the screen on your Android phone or tablet is too small, I now have one heck of a solution for your problem. You can plug a USB mouse and keyboard into the BBB to provide touchscreen and keyboard events. hendersa fucked around with this message at 15:37 on Jun 15, 2013 |

The OUYA hardware has quite a bit more oomph than what I'm working with, but I suppose the concept is about the same. By goal isn't to make some fantabulous thing, but rather to figure out the difficult problems that keep others from using these platforms to do neat stuff. I spend a lot of time writing docs and talking on mailing lists and stuff because new projects are going to run into the same problems that I did. It is my hope that some of those projects are going to find something useful in the collection of things that I helped to figure out with all of my "screw around" projects.
