• YouTube fullscreen not displaying

  - by pt2ph8

  For some reason YouTube videos in my website do not get the fullscreen button, even if I added the parameter allowFullScreen set to true both in the object and embed tag. Here's an example page: http://www.indievault.it/2011/11/09/indie-vault-alla-games-week-2011-online-la-video-gallery/ Just take a quick look at the source. The allowFullScreen param is there, but the button won't show. Here's an excerpt from the code in that page: <object width="540" height="325"><param name="movie" value="http://www.youtube.com/v/dvYQhJwwkgA"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/dvYQhJwwkgA" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="540" height="325"></embed </object>

• How do I optimize SEO in a multiblog WordPress install?

  - by user35585

  We are about to launch two product pages plus a corporate website. The goal is to keep a blog in all of the sites, but here it comes the question about how to do it in a way we get everything unified but do not mess with Google's web crawlers. We considered the following options: Putting a blog from which we retrieve two categories with custom CSS, so we have a blog that sub splits two category-dependent blogs; this way we can get the feeds and will point to it Putting two product blogs of which we retrieve their posts into a bigger, corporate blog Putting three independent blogs Despite I was for the first option, so we only have to address our content from the product pages, I would sincerely like to hear your opinion. We are afraid duplicate content or strange link games may make us lose PageRank. How would you do it?

• Bumblebee stopped working after the today's update

  - by renatov

  I've followed this guide to put Bumblebee to work. Everything was working perfect and I was happy playing my Steam games using primusrun to run them. But after today's update, which updated something related to NVIDIA, Bumblebee is not working anymore: $ primusrun glxgears 2014/06/01 02:36:36 socat[4154] E connect(3, AF=1 "/var/run/bumblebee.socket", 27): No such file or directory primus: fatal: failed to connect to Bumblebee daemon: No such file or directory I'm using Ubuntu 14.04, I have an optimus notebook with a dedicated Nvidia GeForce 730M and an integrated Intel card. Could someone help me, please?

• Threading iPhone

  - by bobobobo

  Say I have a group of large meshes that I have to intersect rays against. Assume also, for whatever reason, I cannot further simplify/reduce poly check count by spatial subdivisioning. I can do this in parallel: bool intersects( list of meshes ) // a mesh is a group of triangles { create n threads foreach mesh in meshes assign to a thread in threads wait until ( threads.run() ) ; // run asynchronously // when they're all done // pull out intersected triangles // from per-thread context data } Can you do this in ios for games? Or is the overhead of thread creation and mutex waiting going to beat-out the benefit of multithreading?

• How to tell Wine that I have changed CD when mounting them virtually on a netbook with no CD drive?

  - by glenatron

  I have been trying to catch up with some of the old games from way back that are about right for my little Aspire One netbook through Wine. I've run into a problem Baldurs Gate, however, which is that I can't change CD. Obviously, I don't have a CD drive, so I have copied the CD content onto an external hard drive and I'm using a mount command with the loopback option to persuade the game that the CD is present. This allowed installation to work correctly and works fine to run it and to play the content from the first CD. However, when the game asks for CD2, I'm stuck. If I mount the CD2 ISO to the CD Rom path it doesn't appear to respond, whether or not I have first unmounted CD1. When I ask Wine to show me the CD drive it contains the right data, but it seems as though whatever signal would be interpreted by Windows to mean the CD drive has been closed isn't being sent. Does anyone know of a way to do this, or am I barking up the wrong tree and there is something else I need to do?

• Render graphics using Doubles in Graphics2D

  - by thedeadlybutter

  Currently, I have a JFrame for my game to render in, and I'm using Graphics2D for drawing (The games graphics are fairly simple 2D sprites). However, my delta variable is a double, and all of the Graphics 2D methods (And Grpahics) use int. I tried to type cast the delta to an int, but it just rounds down to 0. So my question is, how can I render graphics using Graphics2D in Java with coordinates that are doubles. Can I convert it to work with Graphics2D if there is no built in way? Or, is there a graphics library that can support doubles for coordinates?

• Does your team develop their supporting tools or this should be outsourced out of it?

  - by Pierre 303

  By supporting tools, I mean: reference data manager, like virus definition for anti-virus software test data generator level builders for games simulators or advanced mocking systems Does the team building the core product (in the case above, the game or the anti-virus) should be part of the development of the supporting tools significantly, or this is a task you would outsourced out of the team to help it focus on the product? I don't have enough experience to evaluate the pros & cons of each, so I'm hopping you would come up with personal experiences to share, or even studies or papers you read on the subject.

• How to achieve 'forward' movement (into the screen) using Cocos2D?

  - by lemikegao

  I'm interested in creating a 2.5D first-person shooter (like Doom) and I currently don't understand how to implement the player moving forward. The player will also be able to browse around the world (left, right, up, down) via gyroscope control. I plan to only use 2D sprites and no 3D models. My first attempt was to increase the scale of layers to make it appear as if the player was moving toward the objects but I'm not sure how to make it seem as if the player is passing around the objects (instead of running into them). If there are extensions that I should take a look at (like Cocos3D), please let me know. Thanks for the help! Note: I've only created 2D games so was hoping to get guided into the right direction

• record and replay directinput events

  - by cloudraven

  I am trying to build a record and replay system for a couple of games. I was wondering if I can make a general replay engine using directinput rather than doing an specific implementation for each game. Recording DirectInput events doesn't seem to be that much of a problem, but I don't know if there is a way to play them back. My question is, is there a way to feed DirectInput events from a log and make DirectInput believe that they came from mouse/joystick/keyboard? I assume it is unlikely, but if there is a way I would be interested in learning about it.

• How to handle jumping up a slope in a runner game?

  - by you786

  In an 2D endless runner, what should happen when the player is running "too fast" up a slope and jumps? For example, in a "normal" case: .O. . __..O_____ . / . / O/ _/ If he is moving to the right slowly enough, he will jump upwards and land on the flat part of the surface. However, if he is moving too fast, the jump will have no effect as his forward motion will bring him back in contact with the slope before he can get high enough to pass over it. When the speed is sufficiently high, there will effectively be no jump. _________ / .O/ O/ _/ Are there any known ways to solve this issue? I know it's physically correct*, but are there techniques that other games use to overcome this in a reasonable manner? As a last resort I'll have to just remove all slopes that are too slanted. *If you constrain the player to never jumping backwards.

• How Would I create alternate players (Turn base Event)

  - by Blue

  The picture above shows 2 players. Each containing 3 characters. I want to know how to make a Turn based event starting with player 1 alternating turns with player 2. And in every alternation each character gets a turn. If a character dies, the next character on the same team goes, and so on. How would I create this? Is there a tutorial? I haven't made any turn-based games so I don't know how to program these kinds of stuff.

• Is it a good idea to make a game for one aspect ratio and arbitrary screen resolution?

  - by Mimars

  After several very small games I have decided to make something more standalone (2D) and playable. However, I have met the problem of every game that is going to be played in more screen resolutions. Basically, after some research I see that there are several solutions. This seems to be the simplest one: Let's say I define a constant aspect ratio for the game (16:9) and the whole game will be created for a resolution 1680 x 1050. The game will be rendered in this resolution and then I will be able to scale the render to match the player's display resolution. Therefore the game might be playable on almost any resolution, while it would keep the aspect ratio. So, if the game was run on 4:3 display, the top and the bottom of the display would be filled with black color. It seems easy, but my question is - Is this a good approach for a simple game? The game will be simple, but I want to maintain high quality.

• Question about creating a sprite based 2-D Side Scroller with scaling/zooming

  - by Arthur

  I'm just wondering if anyone can offer any advice on how best to go about creating a 2-D game with zooming/scaling features akin to the early Samurai Showdown games. In this case it would be a side scroller a la Metal Slug, the zooming would come in as more enemy sprites entered the screen, or when facing a large sized boss. A feature that would be both cosmetic as well as functional to the game. I've done some reading and noticed a few suggestions that included drawing different sized sprites, a standard size and zoomed out size. Any thoughts? Thanks for your time.

• What is the point in using real time?

  - by bobobobo

  I understand that using real time frame elapses (which should vary between 16-17ms on average) are provided by a lot of frameworks. GetTimeElapsedSinceLastFrame, and it gives you the wall clock time. But should we use this information in basic physics simulation? It looks to me to be a bad idea. Say there is a slight lag on the machine, for whatever reason (say a virus scanner starts up). The calculations all jump, and there is no need for this. Why not use a virtual second and ignore wall clock time? For gameplay on the level of Commander Keen, shouldn't you always use the virtual second and not real-time? (Besides stopwatch timing for race games) I don't see a need to use real time and not a fixed 16ms time step.

• Are VM-based languages becoming viable for Graphics since the move to GPU computing?

  - by skiwi

  Perhaps the title is not the most clear, so let me elaborate it more: I am talking about VM-based languages, by that I mean languages that run on the JVM (java) and for example C#. Also I am talking about 3D graphics, just to be clear. Lately the trend has been that most computing is being done on the GPU and not on the CPU, and since times the issue with programming games on a VM-based language is that garbage collecting may happen randomly. So let's take a look which is responsible for what: Showing the graphics: GPU Uploading graphics to the GPU: CPU? Needs to be done every frame? Calculating physics constraints: GPU Doing the real game logic (Determining when to move objects (independent of physics calculations), processing AI): CPU Is my list actually correct? And if it is, is for example Java becoming more viable? Or is uploading the graphics (vertices) still the most expensive operation? Would like to get more insight into this.

• Should I switch my graphics mode in the BIOS to avoid using Bumblebee?

  - by Fawkes5

  I have just purchased a Acer 3830TG, the timeline X series. To my surprise I found out that there is no first-party support for nvidia optimus for linux. Bumblebee works great, but the battery life from the graphics card always running is not so great. I don't use linux for games so i don't really need the graphics card on, I have Windows for that. In my bios, I have the ability to change my graphics mode from switchable to integrated. If I do this, reinstall ubuntu, what will happen? Will my nvidia card just turn off? Will everything work properly, as if i'm not running an optimus laptop? Is this recommended as opposed to dealing with bumblebee? What is the best thing I could do?

• Will C++ remain viable for game engines in somewhat distant future?

  - by samual

  C++11 has opened ways, which were only dreamt by the C++ programmers. It has been three years since I have been learning C++, and I am going well. Now I want to get into vedio games. Every core of the game code I saw, was monstourously writtern in C++. My question is - If I get into serious game engine dev, and perfecting it would take, maybe say 10 years, would we still be writing game engines in C++ ?(newer standard) Or, will John Carmack, write id tech 7 in c++? note - I am strictly talking about game engines.

• Particles are not moving correctly [closed]

  - by cr33p

  I want to make a particle explosion, after something gets destroyed, but somehow only one line of mixed colors show up on the screen. Here's the header: http://pastebin.com/JW5bPLj2 Here's the source: http://pastebin.com/KHmFqytD I don't get what's wrong, as it's nearly the same as in "Programming Linux Games" Can somebody help me fix that? PS: "Uint32 delta" is needed to update the pixels based on time. PSS: Maybe I should add that it's programmed in C and includes SDL. EDIT: Found the problem. It was the "drawParticles" function. The problem was, that I passed a double to "offset" (as particles[i].x, etc are all doubles). So I ended up with values like ~MAX_INT because I didn't cast the doubles properly to ints.

• MVC? patterns for game development? [closed]

  Possible Duplicate: MVC-like compartmentalization in games? I am thinking of the best way to structure my project and was thought a MVC style pattern would be appropriate. Would be correct having the model handle the majority and basically being the game engine? Are there any standardised patterns recommended for simple game development?

• Building an instance system.

  - by Kyle C

  I am looking into how to design an instance system for the game I am working on. I have always wondered how these are created in games like World of Warcraft, where instances == dungeons/raids/etc). Areas that are separated from players other than those in your group, but have specific logic to them. Specifically how can you reuse your existing code base and not have a bunch of checks everywhere ? if (isInstance) do x; else do y; I don't know if this will make too much of a difference on any answers, but we're using a pretty classic "Object as pure aggregation" component system for our entities.

• How to configure screens in console or create screen configuration profiles?

  - by uncle Lem

  I have two monitors and integrated GPU (Intel® HD Graphics 4600). It works fine for work or movies, but if I launch games in fullscreen mode - I get artifacts, glitches and so on. Temporary disabling second monitor solve this problem, but then I have to enable it back, and set its properties manually (by default, additional screen attaches its left-top corner to main monitor's right-top corner, but I need it to be left-bottom and right-bottom corners). So I need some kind of automatization here. Best option - tool to create and swap between some kind of config profiles. Or, maybe, some console manipulations which I can put into script files would be fine too. (Ubuntu 13.04, if it matters)

• How would I use JBox2d in Java?

  So I did some research and a found Box2d. I then proceeded to download it and the testbed. Now that i have it, I don't know how to properly use it. I'm looking for a clear simple answer on how to use the engine. The things I did was that I put it into a lib folder and referenced the JBox2D jar file. After that i got stuck. How can i use this to program games for android? I'm very confused since Box2d was intended for C++.
