  • What are the general strategies for the server of an FPS multiplayer game to update its clients?

    - by Hooray Im Helping
    A friend and I were having a discussion about how a FPS server updates the clients connected to it. We watched a video of a guy cheating in Battlefield: Bad Company 2 and saw how it highlighted the position of enemies on the screen and it got us thinking. His contention was that the server only updates the client with information that is immediately relevant to the client. I.e. the server won't send information about enemy players if they are too far away from the client or out of the client's line of sight for reasons of efficiency. He was unsure though - he brought up the example of someone hiding behind a rock, not able to see anyone. If the player were suddenly to pop up where he had three players in his line of sight, there would be a 50ms delay before they were rendered on his screen while the server transmitted the necessary information. My contention was the opposite: that the server sends the client all the information about every player and lets the client sort out what is allowed and what isn't. I figured it would actually be less expensive computationally for the server to just send everything to the client and let the client do the heavy lifting, so to speak. I also figured this is how cheat programs work - they intercept the server packets, get the location of enemies, then show them on the client's view. So the question: What are some general policies or strategies a modern first person shooter server employs to keep its clients updated?

  • Where can I buy freely redistributable (creative commons) game assets?

    - by Erlend
    I'd like to know about any 3D asset shops out there that specialize in game assets and, most importantly, license their assets under an open license like Creative Commons or similarly permissive. We are looking to buy some professional looking assets for use and redistribution with our open source 3D game engine. The problem is that all the commercial 3D assets we've come by are only sold under very restrictive licenses, which won't allow us to include the models in our code repository (since free code hosting repositories require that all your data, including media, is open source or otherwise copyleft) nor in turn redistribute the assets as part of our downloadable SDK. I realize this sounds like a weak business idea, since users could just buy the asset and start sharing it with everyone. But somehow this has worked for hundreds of WordPress theme shops, so I was hoping maybe someone's trying similar things for commercial game assets.

  • Good book/resource recommendation for HTML5 mobile game development?

    - by Greg Bala
    The problem: I am taking an existing, 5 year old, html based MMORTS game and "HTML5-ing" it, "AJAX-ing" it and most importantly, optimizing for mobile devices like iPhone, android etc. For these devices, the application will be packaged as a downloadable app that is a wrapper for a browser which actually shows the game.. The Question Looking for a good book, or books, or in-depth articles that would help me learn: what tools I have in iOS, andriod applications for optimizing an html based game. things like caching of images, etc what kind of connectivity, or interactivity I can expect between the html/javascript pages and the wrapper - can I play sounds in the wrapper by triggering them from javascript? etc tip and tricks to optimize html/html5 & Javascript application to run well on mobile devices ETC :) Any recommendations would be greatly appreciated!!

  • Size limit while using UICollectionView as tiled map for iOS game?

    - by Alexander Winn
    I'm working on a turn-based strategy game for iOS, (picture Civilization 2 as a template example), and I'm considering using a UICollectionView as my game map. Each cell would be a tile, and I could use the "didSelectCell" method to handle player interaction with each tile. Here's my question: I know that UICollectionViewCells are dequeued and reused by the OS, so does that mean that the map could support an effectively infinitely-large map, so long as only a few cells are onscreen at a time? However many cells were onscreen would be held in memory, and obviously the data source would take up some memory, but would my offscreen map be limited to a certain size or could it be enormous so long as the number of cells visible at any one time wasn't too much for the device to handle? Basically, is there any memory weight to offscreen cells, or do only visible cells have any impact? Also, does a UICollectionView seem like a bad idea for a game map, in a way I haven't thought of yet? It seems like it work well, but I haven't tried it yet so any thoughts are welcome.

  • E3 Booth Babes Display a Painful Lack of Video Game Knowledge [Video]

    - by Jason Fitzpatrick
    If you thought a prerequisite for manning a booth at an electronics expo was a passing knowledge of the electronics and games you were promoting, you were wrong. In the above video Chloe Dykstra puts a set of “booth babes” from the E3 2011 conference to the test by asking them simple questions about video games both new and old. If you’re a gaming fan and you can watch this video without laughing out loud you’ve got an iron will (or you’re shaking your head in disbelief that someone could work a gaming convention and not know the answers to these questions). We won’t lie, we were shaking our head when the one model admitted that she’d worked at GameStop for a year and still didn’t know any of the answers. What questions would you put on list? How about “Finish this sentence: ‘Your Princess is in another…’”, “Dimension?”. 5HP: Booth Babe Edition – E3 2011 [YouTube via Kotaku] How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • The Customer Experience Imperative: A Game Changer for Brands

    - by Jeri Kelley
    By Anthony Lye, SVP, Cloud Applications Strategy, Oracle We know that customer experience has emerged as a primary differentiator for businesses today.  I’ve talked a lot about the new age of the empowered consumer. At Oracle we’ve spent a lot of time developing technologies and practices that our customers can implement to greatly improve their customer experience strategies. Of course I’m biased, but I think that we have created a portfolio of the best solutions on the planet to help organizations deal with the challenges of providing great customer experiences. We’ve done this because we started to witness some trends over the last few years. As the average person began to utilize social and mobile technologies more frequently and products commoditized, customer experience truly remained the only sustainable differentiator for businesses.In fact, we have seen that customer experience is often driving the success or the failure of a product or a brand. And as end customers have become more vocal about their experiences with companies on social and mobile channels, they now have the power to decide which brands will win and which brands will lose. To address this customer experience imperative, I believe that business today must do three things really well:Connect with your customers. You have to connect with customers whenever, wherever and however they want. Organizations must provide a great experience on their existing channels— the call center, the brick and mortar store, the field sales organizations, the websites and social properties. Businesses must also be great at managing and delivering journeys on these channels, while quickly adapting to embrace the new channels that emerge. You have to understand mobile. You have to understand social. You have to understand kiosks. These are all new routes to market, new channels where your customers may or may not show up. You have to interact with them where they are. You have to present information in a way that's meaningful to them. As well as providing what we would call a multichannel experience. We have to recognize that customers may start their experience on one channel, but end it on a different channel. It’s important that an organization’s technology solutions enable, not just a multichannel strategy, but a strategy that can power new channels and create customer journeys that cross these channels.Get to know your customers. Next, companies need to get to know the customer as intimately as the customer will allow. Today most customer interactions are anonymous, but it’s important for brands to know which customers drive value. Customers want to provide feedback. They want to share their opinions, but they want to know that those opinions are being heard and acted upon. For this to occur, we need to know much more about the customer and then reward them for their loyalty and for their advocacy.Enable connections. The last thing is to enable people to connect or transact with your brand. We've got to make it really, really simple for customers to do business with us. We can't make them repeat the steps; we can't make them tell us their identity for the fifth time as they move between organizations. These silos can no longer sustain or deliver a good customer experience. It's extremely important that companies be where customers want them to be—that we create profitable journeys for us and for them.Organizations have to make sure that there is a single source of truth that defines the customer. We have to make sure that the technology applications that we rely on understand not just the dimensions of multichannel, but of cross-channel too. We have to enable social at the very core of the overall architecture. We have to use historical analytics, real-time decisioning as well as predictive analytics to help personalize and drive an experience. And these are all technologies that IT needs, that IT is familiar with, but needs to enable for the line of business that in turn can enable for the end customer.  This means that we've got to make our solutions available to the customers in the cloud.In this new age of the empowered consumer, businesses have to focus on delivery mechanisms that reduce the overall TCO, while driving a rapid rate of innovation and a more rapid rate of deployment. At the Oracle Customer Experience Summit @ OpenWorld, I’ll discuss these issues and more. I hope that you can join us for what promises to be an unforgettable experience.

  • How can i get latency when using Game Center?

    - by Freddy
    I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

  • Game Development In C Only. Is it possible?

    - by Ishan Sharma
    I am a first year college student in India and want to make a small game as a this semester project. I am quite good at C and am learning it rapidly but I wanted to ask if developing a game entirely in C(no C++ or C#m I'd love to use these but for college projects, we have strict requirements of using only C). What I am looking for is a simple top view driving game. It won't have anything fancy and even the visual things will be powered by simple characters. For example, user controlled car can be represented by ¦ and edges of road by series of |'s. What do you think?
