  • How do I render terrain in a 2.5D perspective, like in the game Don't Starve?

    - by Hamdan
    I have experience in making 2D side scroller games such as Terraria, but now I want to challenge myself and make a game that has a 2.5D perspective. The game I am trying to mimic is Don't Starve. Right now my focus is on figuring out how to render the ground. I am having a hard time figuring out how they generated the ground, and then rendered it. The way I think they rendered the ground is by first painting the ground in some paint program, and then somehow manipulating that flat image so that it appears to have depth. I am completely confused by how you would actually render that type of terrain. I want the terrain to have the following features: Look like the terrain in Don't Starve, here is a video showing the terrain in Don't Starve The terrain will be flat, and the camera's angle and perspective will be fixed Any tips and hints will be appreciated, Thank you in advance. (I am working in Java, using the Light Weight Java Game Library (LWJGL).)

  • Xubuntu 12.4 upgraded fine but there are everywhere pale grey windows/menus with white fonts!

    - by Costa
    I upgraded to Xubuntu 12.4 through the update manager. Everything works fine except that many windows and menus (Ubuntu Software Center,Transmission properties etc) apear in pale grey with white fonts. For examle, it's impossible to read n change properties on Transmission. Titles apear excellently, the rest is really hard to read: white text on allmost white background ... I have tried already:rebooting, changing theme/apearance photo1 http://en.zimagez.com/zimage/-26042012-102025.php When login as guest everything works fine. I created a new account, all is fine photo2 http://en.zimagez.com/zimage/-26042012-103258.php But I still want my initiall user-account which i had so well tuned...

  • Where do I find display brightness controls in Lubuntu?

    - by dlanod
    I'm looking for a control to be able to change my standard display brightness in Lubuntu. I've tried How do I set default display brightness? but my system settings does not include a Screen option. I've also tried Power Manager, Monitor Settings and Screensaver under Preferences and couldn't spot anything to control this option. The function key mappings (this is a laptop) work to change the brightness, but I'm looking for a UI option as the laptop is physically set up to be mouse-based (keyboard is hard to access with how we've got it set up).

  • I want to record a screencast of a processing sketch

    - by nathanvda
    I have a created a music visualisation using Processing. I now want to convert that to a video, and the least obtrusive way I could think of is to record a screencast. I figured exporting Processing to video including audio, from within Processing itself, on ubuntu seemed an unsolved issue. Very hard and also could cause timing sync issues (since the music keeps running while images are captured). So move on to the screencast method. Dead-easy, I figured. But I was wrong. First hurdle was to find a way to record the sound from the audio (and not the mic). I did find a tutorial for that here. In short: use gtk-recordmydesktop and pulse audio. But, apparently, what happens: Processing does not use ALSA. When the sound is playing, it does not appear in the Pulse Audio mixer. How can I record the audio now?

  • Grub can't find device on boot resulting in Grub Rescue

    - by user1160163
    So I have 2 hard drives a HDD 320GB and a SSD 20GB. Before I had Windows 7 on the HDD and Ubuntu on the SSD but wanted to get rid of windows and reinstall a clean Ubuntu on the SSD then use the HDD for storage. So I deleted everything from the HDD and set up the SSD with 18GB ext4 and 2GB Swap and installed Ubuntu on the 18GB ext4. Though now when I boot up I get "Error: No such device Grub Rescue" I have a live USB and I ran the Boot Repair following these instructions - grub rescue after install of Ubuntu 12.04 (dual boot) - it says successful though still have the same problem. This is the given URL from Boot Repair - http://paste.ubuntu.com/1257988/ Thanks for any help given.

  • How best to take a users signature online? (UK law orientated) [closed]

    - by Ben Griffiths
    Not sure if this is the best place to ask, but I can't seem to find any of the other SE sites that would fit better (unless there's a law one?) I'm building an application that will replace an existing paper based form, and this form would normally be signed by the person filling it in. Looking around, it's hard to find a good definitive resource to explain what I can and cannot accept as far as a signature goes. It looks like some UK government online forms accept just your name typed into a box, but I've also heard you should back up with an email - so that process would be type name into a box along with providing an email address, send out an email, then make them click a link within the email to finally complete the verification. Involving email seems very long winded and leaves the system open to spam filters blocking emails, forgotten emails that just sit in inbox's etc. So, does anyone have any knowledge in this department? Personally, I'd love to just get them to type their name into a box and be done with it!

  • Is it bad practice to use <?= tag in PHP

    - by marco-fiset
    I've come across this PHP tag <?= ?> recently and I am reluctant to use it, but it itches so hard that I wanted to have your take on it. I know it is bad practice to use short tags <? ?> and that we should use full tags <?php ?> instead, but what about this one : <?= ?>? It would save some typing and it would be better for code readability, IMO. So instead of this: <input name="someVar" value="<?php echo $someVar; ?>"> I could write it like this, which is cleaner : <input name="someVar" value="<?= $someVar ?>"> Is using this operator frowned upon?

  • How relevant is PHP today for browser games?

    - by Bitgarden
    I was the lead developer of 2 moderately successful browser games quite a few years back, and plan on working on a new game soon. At the time, I wrote them in pure PHP (no template engine or anything of the sort). I'd like to start working on a new game, but have been out of the web development world for a while. Reading around, I hear a lot of good about Rails, Django, Node.js, etc., with which I have no experience (although I know my way around Python, Javascript, and the others quite well). So my question is the following- if I were to go in my old ways and go with PHP again, would I be making things hard for myself? Would picking something more "trendy" have a real impact on my development? In addition, does anyone have any pointers relating to specifically developing browser games with these more modern tools?

  • Mounting Samba share whenever it's available, unmounting when it's not

    - by Laurynas Biveinis
    I am trying setup permanent samba share mounts. That's not too hard using these instructions. But, I want them to Automatically remount whenever I join the network where these shares are available. Automatically unmount (or make access requests fail immediately instead of hanging) whenever I leave the network, i.e. avoid this automatically. Googling suggests that AutoFS might be helpful. I gather it takes care of the 1. above but I am not sure about the 2. The other questions about automated Samba mounts, i.e. How to mount a samba share permanently?, do not seem to address automatic remounts/unmounts, so I think this is not a duplicate. Thanks.

  • Update live USB distro?

    - by qubex
    I have Lubuntu 14.04 (and Ubuntu 14.04) on a pair of USB disks created by writing the img files to USB using dd on Mac OS X. Unfortunately these systems both have some known bugs (that have since been corrected) and lack certain important drivers for my system (which I have located online). How can I make the USB disks writable and how do I update the distribution upon them as one may do for a locally-installed system? And if I later proceed to install from these USB sticks onto a hard-drive, will they ‘carry’ the package and driver updates with them or will I have to start from scratch again? (I seem to remember from my ancient Windows XP days that such procedures were referred to as ’slipstreaming’ or somesuch on that side of the fence.) (No, I did not create a persistence partition when I created the sticks, because from Mac clearly that isn’t an option. And anyway, as I imperfectly understand it, the persistence partition is for user files and not for the modification of the system.)

  • How can I obtain in-game data from Warcraft 3 from an external process?

    - by Slav
    I am implementing a behavior algorithm and would like to test it with my lovely Warcraft III game to watch how it will fight against real players. The problem I'm having is that I don't know how to obtain information about in-game state (units, structures, environment, etc.) from the running WC3 game. My algorithm needs access to the hard drive and possibly distributed computing, that's why JASS (WC3's editor language) isn't appropriate; I need to run my algorithm from a separate process. Direct3D hooking is an approach, but it wasn't done for WC3 yet and a significant drawback of that approach would be the inability to watch how the AI performs online, since it uses the viewport to issue commands. How I read in-game data from WC3 in a different process in a fastest and easiest way?

  • Find angle for projectile to meet target in parabolic arc

    - by TheBroodian
    I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)? The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?

  • Splitting Logic, Data, Layout and "Hacks"

    - by fjdumont
    Sure, we all heard of programming patterns such as MVVM, MVC and such. But that isn't really what I'm looking into as Layout, Data and Logic is already pretty much split up (XML-Layout markup, Database, insert your language of choice here). The platform I am developing for is hard to maintain over the updated versions and older OSes. The project significantly grew up over the last few months and dealing with different platform versions really is a pain. For example simply disabling an user interface control for all existing versions took me around 40 lines of code in the logic layer, wrangling around with invocation, delegation, singletons that provide UI handling and so on. Is there a clean way to keep track of those "hacks" by maybe excluding it into separate classes or even packages? Should I overwrite existing framework code in order to handle my requirements correctly? If so, does that concept have a name?

  • Ubuntu Variant / Linux Distros which uses least system resources (RAM, CPU)?

    - by elegantonyx
    I have a netbook (an older Asus EEEPC 1005HA) which I want to get rid of Windoze on (I like Windows, but I don't think it works well in a netbook environment). Basically, my question is which Ubuntu variant will use the least RAM and CPU running idle, and/or the same question except when running Firefox and Libreoffice Writer, say. I am also open to suggestions of non-Ubuntu Linux distros, but since this is AskUbuntu I thought the first question would be more appropriate. I have a disk drive which I can attach to the netbook, so it doesn't have to be a Ubuntu Variant / Linux Distro which solely boots from a USB drive. I have at my disposal: DVDs, DVD writer/ disk drive, 4gb flash drive, 8 gb flash drive I was thinking either Lubuntu or Archbang / Crunchbang but I would like some help from more knowledgable people Specs: Can't boot into it right now, but I think I have either Intel Atom N270 @1.60ghz OR Intel Atom N280 @1.66ghz (single core, I think) 2gb RAM 160 GB hard drive

  • What is MVC, really?

    - by NickC
    As a serious programmer, how do you answer the question What is MVC? In my mind, MVC is sort of a nebulous topic — and because of that, if your audience is a learner, then you're free to describe it in general terms that are unlikely to be controversial. However, if you are speaking to a knowledgeable audience, especially an interviewer, I have a hard time thinking of a direction to take that doesn't risk a reaction of "well that's not right!...". We all have different real-world experience, and I haven't truly met the same MVC implementation pattern twice. Specifically, there seem to be disagreements regarding strictness, component definition, separation of parts (what piece fits where), etc. So, how should I explain MVC in a way that is correct, concise, and uncontroversial?

  • Creating an Ubuntu live USB for use with Gparted

    - by Jeff
    I've install Ubuntu 12.04 on my Windows 7 Dell laptop. Recently I discovered that I'm running out of space on my Ubuntu partition, and I would like to enlarge it. Is it safe to resize partitions while they're in use e.g. when I'm logged into Ubuntu? If so, I've ran into this problem when I run GParted: It seems as if my hard drive is one big, NTFS partition, like the Ubuntu partition doesn't exist. Is it possible Ubuntu runs off the NTFS partition, sharing it with Windows? What should I do?

  • Function that requires many parameters

    - by user877329
    I have a problem related to this: Are there guidelines on how many parameters a function should accept? In my case, I have a function that describes a rounded rectangle. The caller specifies An integer which determines how the rectangle should be merged into previously created shapes An Anchor, which is a point that is used for alignment (right, left, top, bottom etc). (0,-1) means that position (next parameter) describes the top, middle point of the rectangle. The position of the rectangle Width and height Corner radius Should I use Parameter Object pattern in this case? It is hard to see how these parameters are related

  • How do you describe your profession in a public place or conference?

    - by Jenko
    I've often been in situations where non-technical people ask me, "So, what do you do?" ... and I've found it somewhat hard to describe that I spend the entirely of my days pouring over colored text. Of course, its quite reasonable to say "I design software" or "I develop computer applications", but that still feels somewhat "lame" and generic. So how do you describe your profession in public situations? are there any insights for those of us less gifted in public speaking?

  • How much do they study in the best universities, relative to the other universities?

    - by Velizar Hristov
    In my university, our total required weekly attendance (for lectures and tutorials/similar) is about 12 hours. It was like that in the first year, and then everything required extremely little effort - I believe that if I invested as much efforts as someone who is studying for medicine or law, I could have learnt everything for 1-2 months - if not less! Now I'm second year and it doesn't look like it's going to be too different. This concerns me about the people who study in Oxford, Cambridge or Imperial College. It would be weird if they study that little, and it would be very concerning if they do study very hard, because this would mean that by the end of the year, their first year students will be better than our average third year student. Which is bad news for me, given that I share the market with them. I know the question can't have an absolutely accurate answer, but it can still be answered quite definitely, and it's relevant to many people.

  • Letting go of a project

    - by SkyOrg
    I've been the sole developer of a niche product for my company for nearly 6 years. I've grown quite attached to the project and I enjoy working on it. However, it was the decision of management to take the project out of my hands and move it under the wings of another team. Unfortunately, I'm having a hard time letting go of the project. I'm sad to see it leave my hands since I've put so much time into it and enjoyed working on it, but it also allows me to work on new things. I've even caught myself being a bit hostile to the other team, which is poor on my part. How can I convince myself to just let it go?

  • How to study for an Informatics Olympiad [on hold]

    - by Cloud
    One of my goals for next year is to participate in the Australian Informatics Olympiad. As far as I'm aware, it is not too different from Informatics Olympiads in other countries. What would be the best way to study for this? What content should I pay particular attention to while learning in Python? I am currently using the book 'Learn Python the hard way', but are there any other books worthy of a mention? This is the link to their site: http://orac.amt.edu.au/aio/ It contains sample questions, so you can get an idea for the structure or nature of the competition. I know this isn't really a specific programming question, but it would be great if someone could share their experience or give some suggestions for me.
