  • Saving a list of points into a text file

    - by dylanisawesome1
    I recently posted a question about this, but was not really sure where to go. I've gotten some progress, and have generated some simple noise here: http://pastie.org/5408655 That works well enough for me, but I would really like to be able to save the points into an ascii text file. currently it's formatted so that something like this: http://pastie.org/5409311 would create a square. I need to save in this format with the points(and lines connecting them) generated in the method above. Essentially, I need to write the array of points created in the first example to a text file formatted like the second example.

  • 3D game editor with C++ support and Bullet Physics

    - by Raghav Bali
    I am very new to game development and hence the question. Is there any open-source game editor that uses Bullet Physics engine with C++ code edit support.I have read about blender but it allows python based editing(if I am not wrong here). I need an editor to quickly draw the needed objects and concentrate more on the logic on their interactions(mostly magnetism based). This(my project) is part of an already existing legacy code in C++ which is forcing the dependency. Also, is there any physics engine which provides support for magnetism? Any help will surely be great. Thanks

  • A good way to build a game loop in OpenGL

    - by Jeff
    I'm currently beginning to learn OpenGL at school, and I've started making a simple game the other day (on my own, not for school). I'm using freeglut, and am building it in C, so for my game loop I had really just been using a function I made passed to glutIdleFunc to update all the drawing and physics in one pass. This was fine for simple animations that I didn't care too much about the frame rate, but since the game is mostly physics based, I really want to (need to) tie down how fast it's updating. So my first attempt was to have my function I pass to glutIdleFunc (myIdle()) to keep track of how much time has passed since the previous call to it, and update the physics (and currently graphics) every so many milliseconds. I used timeGetTime() to do this (by using <windows.h>). And this got me to thinking, is using the idle function really a good way of going about the game loop? My question is, what is a better way to implement the game loop in OpenGL? Should I avoid using the idle function?

  • Redirecting non existing post to homepage; is that good for SEO?

    - by BlackEagle
    I am checking my website out on Google Webmasters and I am seeing an astonishing 5000 links that could not be found by Google's Crawlers. That's normal, because my website is built in a manner that users can drop their own things, which also lead to 404 pages. Not a problem at all if I can find a workaround of course... So my question is: what if I made a function or a mod rewrite that will check if the link exists (a post for example) and if not, it will redirect it to the home page. Is this good for SEO? Will Google see this as 'link found'? How do I have to look at this problem?

  • Artist, Looking to lean how to program games, where do I start? [on hold]

    - by Christopher Hindson
    I have bean an artist for many years now I am very comfortable with using Photoshop and Flash but I want to learn how to but together my own games, I bean doing my own research into this and at the moment I am at little bit stuck on witch direction to go down. So my question is witch programming language should I learn? I have already bean looking into this what i understand is that Gamemaker with its built in language (GML) is one of the most friendly to people who are new to the game making world. I have played around with this program and was pretty happy with it but I want more also you can use Unity with language such as C and javascript and then games built with Java witch looks interesting. One more thing before you send your answer in at this moment in time I would only be able to make 2D game but 3D isn't out of the picture.

  • Ubuntu: how to change the right click "open with" application order?

    - by ramgorur
    I am using Ubuntu 10.10 Maverick, when I try to open a plain text file using a program x, I do right click to access the "open with" application list. Suppose my current "open with" list is like below -- application z application y application x But I want it to be like -- application x application y application z i.e. I want to change the order of the list. I know that I can fix a "default program" for a particular file, but that's not what I am looking for. My question is which file defines this "open with" preferences? and if there is any way to tweak it. Any idea?

  • When should I increment version number?

    - by ahmed
    I didn't learn programming at school and I do not work as a (professional) developer, hence a lot of basics are not quite clear to me. This question tries to clarify one of them. Now let's suppose that I have issues #1, #2 and #3 in my Issues Tracker that are set to be corrected/enhanced for version 1.0.0 and that the last (stable) version is 0.9.0. When should I increment to version 1.0.0 ? When a) just one of the listed above issues is closed or b) when all the issues related to version 1.0 are closed ? Which one is the right way to do it ? And by the right way, I mean what is currently used in the industry. Thanks.

  • Water Simulation in LIBGDX [on hold]

    - by Noah Huppert
    I am doing some R&D for a game and am now tackling the topic of water. The goal Make water that can flow. Aka you can have an origin point that water shoots out from or a downhill slope. Make it so water splashes, so when an object hits the water there is a splash. Aka: Actual physics water sim. The current way I know how to do it I know how to create a shader that makes an object look like its water by making waves. Combined with that you can check to see if an object is colliding and apply an upwards force to simulate buoyancy. What is wrong with that way The water does not flow No splashes Possible solutions Have particles that are fairly large that interact with each other to simulate water Possible drawbacks Performance. Question: Is there a better way to do water or is using particles as described the only way?

  • Dell XPS 15 with Ubuntu 12.10 and HDMI working on hybrid graphics

    - by karolsojko
    So there is a lot of buzz about hybrid graphics being shitty and having a weak support. I'm currently considering buying a new laptop. Dell XPS 15 caught my eye. I will use it for work as well so I will need a large monitor for it connected by HDMI. The question is: has someone got a Dell XPS 15 and can confirm that hybrid graphics support is working fine on 12.10 with no issues on the HDMI. I ask this because all the buzz about the subject stops on 12.04 - does this mean that it's all ok now :) ?

  • Wireless speed drops over time and doesn't get up if not reconnected

    - by Vili Lehto
    I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

  • Change Logging Level for SOA 11g

    - by James Taylor
    I’m sure there are many blogs out there that have this solution. But I seem to get asked this question a lot so I thought I would post it here for my convenience. Login to Enterprise Manager, e.g. http://localhost:7001/em Expand the SOA folder and right-click the soa-infra(soa_server1) folder and select Logs – Log Configuration Navigate to the component you want to monitor and change the log level. It is possible to change at a parent level if required It is not recommended that you set the level to FINIEST at a parent level as it will generate a lot of logging. Make sure you apply the change to take affect. Simple as that.

  • How can I boot into Windows from GRUB rescue WITHOUT CD drive?

    - by user103968
    I took this from another website's string where i found no good answer This is my situation: installed Ubuntu without a CD (using A USB) dual boot installation (Windows 7+Ubuntu) didn't like the installation and decided to boot into Windows and delete the Linux partitions forgot to fix the mbr from within Windows Now, when I boot, I am stuck in the GRUB rescue limbo. Simple question: How can I boot into Windows from GRUB rescue? I cannot boot from CD because I don't have a CD drive, therefore the usual solutions (recovery CD etc) do not work. Any hints? Is there a way i can maybe do this through a USB? Thanks

  • Apple New Year alarm bug cause

    - by StasM
    As many people know, Apple has a bug in their iPhone that prevented alarms from going off at 1st and 2nd of January 2011. What is strange is how that bug might happen - i.e., as far as I know this bug happens in all timezones and nobody is switching off DST on Jan 1st, so it's not timezone or DST-related. Also, Jan 1st seems to be nothing special as a UNIX timestamp, so something like sign change or integer overflow can't be the reason. It is highly improbably that alarm code has something like if(date == JANUARY_1_2011 || date == JANUARY_2_2011) turn_alarms_off(); - that would be a sabotage and not a bug. So the question is - could you imagine and describe a bug that would cause the alarm to fail exactly at Jan 1st and 2nd everywhere while letting it work otherwise, without specifically referring to those exact dates? Of course, if somebody knows the real cause, that would be a definite answer, but if nobody knows it - I think it is interesting to think what might be the cause of such strange bug.

  • Advice: How to overcome the "accent" barrier in cross-geographical teams ?

    - by shan23
    I'm an Indian working in a MNC. As a result, I often have to attend(and contribute) to meetings where I have to listen to people who have a pronounced American accent. Some are still understandable, but a couple of people I have interact with speak such a different form of English, I mostly have to guess at what they are saying. When I ask them to clarify, they often speak the same sentence in the same tenor/speed, so my net gain is zero. My question is, how to politely put it across that due to their accent, I can't understand a thing, and may they please speak slowly and a bit clearly ? Some people might take it a bit personally, since "everyone else" is understanding them perfectly...and I don't want to cause offense at all. Any ideas ?

  • Finding Telecommuting Opportunities as a Recent College Graduate

    - by stanigator
    Reading the answers to hiring practices of remote vs. local employees and freelance programming sites, I would like to add this question to the mix. I am a recent college graduate from an electrical engineering background with 2 years worth of work terms in programming (C, C++, VBA, Matlab, etc.) while I was still in school. While I am interested in learning other software tools (such as Python, Ruby on Rails, Javascript, etc.), I want to use the tools I have now in a telecommuting role while I grow my toolset. Despite having 2 years of work experience (and I've lost track of when I have started programming), my status as a recent college graduate may be an obstacle of my credibility to compete for telecommuting (or in fact any) programming opportunities. I don't know how I can go about finding telecommute programming opportunities for someone with my situation. Overall, many of previous places I've worked at liked my work. What are your suggestions? Thanks in advance!

  • Got an idea for an application, but part of it is patented, any suggestions?

    - by tekiegreg
    so I've been working on developing an idea for an application that I think has the potential to be successful, however after some initial research I've discovered that at least part of my ideas are covered by a patent out there, the patent in particular is held by a really large company (I don't want to give away specifics for fear I'd draw their attention for sure). I'm debating a few options: 1) Develop patents around my ideas that don't conflict and maybe approach the company in question for a license exchange 2) Just approach them for a license outright 3) Just develop around it anyways and hope for the best :-p What have other people done in these situations? Are companies generally willing to grant patent licenses? Are they willing to grant them at reasonable prices? Thoughts?

  • How to test robots.txt in googlebot to find out what is being indexed

    - by Amar Jarubula
    This question is a continuation for this answer How to check if googlebot will index a given url? As was told I did go to the Webmaster Tools and tested contents of my robots.txt file. However this is just giving me the info if that content is good enough or not. However for my scenario I need to test whether disallowing some patterns is being indexed or not. For example I have something like this below in my robots.txt disallow:/pattern* My understanding is the URLs with word pattern should not crawled, but how do I test this pattern is enforced while indexing the website?

  • Why is Conway's "Game of Life" used for code retreats?

    - by blunders
    Code Retreat is an all-day training event that focuses on the fundamentals of software development. There's a "global" code retreat day coming up, and I'm looking forward to it. That said, I've been to one before and have to say there was a huge amount of chaos... which is fine. One thing that I still don't get is why the "Game of Life" is a good problem for TDD, and what good and bad TDD for it feels like. Realize this is a pretty open ended question, so feel free to comment.

  • which kernels can I safely purge?

    I use the main answer of this question quite often to clear some space, but now I'm in extreme need and I'd like to better understand which kernels are safe to purge, my list is the following 10:50:58-673 - ~> dpkg -l | grep -Eo "^.i +linux-(image|headers)[^ ]+" | cut -c 5- | grep --color -E "$|"`uname -r` linux-headers-2.6.38-15 linux-headers-2.6.38-15-generic linux-headers-2.6.38-15-generic-pae linux-headers-2.6.38-16 linux-headers-2.6.38-16-generic linux-headers-2.6.38-16-generic-pae # current one linux-headers-generic linux-headers-generic-pae linux-headers-server linux-image-2.6.38-15-generic-pae linux-image-2.6.38-16-generic-pae linux-image-generic-pae linux-image-server Is it enough to keep linux-headers-2.6.38-15 linux-headers-2.6.38-15-generic linux-headers-2.6.38-15-generic-pae linux-headers-2.6.38-16 linux-headers-2.6.38-16-generic linux-headers-2.6.38-16-generic-pae # current one Or would this be enough linux-headers-2.6.38-15-generic-pae linux-headers-2.6.38-16-generic-pae # current one Or which other would be the shortest (keeping the previous one too)?

  • graphical interface when using assembly language

    - by Hellbent
    Im looking to use assembly language to make a great game, not just an average game but a really great game. I want to learn a framework to use in assembly. I know thats not possible without learning the framework in c first. So im thinking of learning sdl in c and then learn, teach myself, how to interpret the program and run it as assembly language code which shouldnt be that hard. Then i will have a window and some graphics routines to display the game while using assembly to code everything in. I need to spend some time learning sdl and then some more time learning how to code all those statements using assembly while calling c functions and knowing what registers returned calls use and what they leave etc. My question is , Is this a good way to go or is there something better to get a graphical window display using assembly language? Regards HellBent

  • Number of Classes in a Namespace - Code Smell?

    - by Tim Claason
    I have a C# library that's used by several executables. There's only a couple namespaces in the library, and I just noticed that one of the namespaces has quite a few classes in it. I've always avoided having too many classes in a single namespace because of categorization, and because subconsciously, I think it looks "prettier" to have a deeper hierarchy of namespaces. My question is: does anyone else consider it a "code smell" when a namespace has many classes - even if the classes relate to each other? Would you put in a lot of effort to find nuances in the classes that allows for subcategorization?

  • How can I store post rankings that change with time?

    - by Daniel Fein
    I'm trying to learn how to code a website algorithm like Reddit.com where there are thousands of posts that need to be ranked. Their ranking algorithm works like this (you don't have to read it, its more of a general question that I have): http://amix.dk/blog/post/19588 Right now I have posts stored in a database, I record their dates and they each have an upvotes and downvotes field so I'm storing their records. I want to figure out how do you store their rankings? When specific posts have ranking values, but they change with time, how could you store their rankings? If they aren't stored, do you rank every post every time a user loads the page? When would you store the posts? Do you run a cron job to automatically give every post a new value every x minutes? Do you store their value? Which is temporary. Maybe, until that post reaches its minimum score and is forgotten?

  • Creating a level editor event system

    - by Vaughan Hilts
    I'm designing a level editor for game, and I'm trying to create sort of an 'event' system so I can chain together things. If anyone has used RPG Maker, I'm trying to do similar to their system. Right now, I have an 'EventTemplate' class and a bunch of sub-classed 'EventNodes' which basically just contain properties of their data. Orginally, the IAction and IExecute interface performed logic but it was moved into a DLL to share between the two projects. Question: How can I abstract logic from data in this case? Is my model wrong? Isn't cast typing expensive to parse these actions all the time? Should I write a 'Processor' class to execute these all? But then these actions that can do all sorts of things need to interact with all sorts of sub-systems.
