  • 2D pathfinding - finding smooth paths

    - by Kooi Nam Ng
    I was trying to implement a simple pathfinding, but the outcome is less satisfactory than what I intended to achieve. The thing is units in games like Starcraft 2 move in all directions whereas units in my case only move in at most 8 directions (Warcraft 1 style) as these 8 directions direct to next available nodes (they move from a tile to next neighboring tile). What should I do in order to achieve the result as in Starcraft 2? Shrink the tile size? On the picture you can see a horizontal line of rock tiles being obstacles, and the found path marked as green tiles. The red line is the path I want to achieve.

  • Reading mp3 metadata?

    - by Blaze
    I am planing on writing an application using Vala. Its purposed is to import mp3 files from a location and rename them if necessary. The renaming information should be provided by the ID3 tags in the mp3 file such as the title and the number of the song. My target platform is Ubuntu (Linux). As the question says, I am searching for how can I achieve this on Vala. I think this functionality might be provided by Gstreamer.

  • OT: March Mdness 2011

    - by RickHeiges
    This past fall, I decided to take a break from Fantasy Football. Did I miss it? Yes to some extent. Fantasy Football can really eat up a lot of time. But - I still love March Madness (NCAA Men's Basketball Tourney). It doesn't take much time to pick out teams. Since you can't make any changes after the deadline and the computer keeps track of scoring/scenarios/etc, it is a fun thing that really takes a little time and can help you enjoy the games a bit more. Let's see how good you are at picking...(read more)

  • Game Sound Effects Availability

    - by Ben
    Is there a need in the community for affordable game-focused sound effect packs? I am considering putting together some effects specifically geared toward games and indie developers that desire to get a working prototype quickly off the ground. Is there a need for this, or is there another standard "go-to" spot for this kind of thing? I want to offer value to the community but wanted to assess the need first. If anyone has thoughts, insight, or personal opinions on this I would love to hear it!

  • How can I create a 3D model in Java without using modeling software?

    - by Galen Nare
    I am a lightly experienced game developer and this is my first time trying 3D objects in Java for the first time. I have been recently creating and updating games using AWT, Swing, and Graphics, but I want to delve farther into Java. I have looked into Java3D, but it's not what I want. I want to use Images and then crop the Image and place the respective textures in their respective places. I already know how to do the cropping and 2D Image editing, but how do I go 3D?

  • Learning to optimize with Assembly

    - by niktehpui
    I am a second year student of Computer Games Technology. I recently finished my first prototype of my "kind" of own pathfinder (that doesn't use A* instead a geometrical approach/pattern recognition, the pathfinder just needs the knowledge about the terrain that is in his view to make decisions, because I wanted an AI that could actually explore, if the terrain is already known, then it will walk the shortest way easily, because the pathfinder has a memory of nodes). Anyway my question is more general: How do I start optimizing algorithms/loops/for_each/etc. using Assembly, although general tips are welcome. I am specifically looking for good books, because it is really hard to find good books on this topic. There are some small articles out there like this one, but still isn't enough knowledge to optimize an algorithm/game... I hope there is a modern good book out there, that I just couldn't find...

  • Software installed on root partition or on home partition

    - by Tim
    I am planning to install some big softwares such as Matlab (4GB), Mathematica (4GB) on my Ubuntu partitions. I was wondering if I installed them on my home partition, when I reinstall Ubuntu without touching the home partition, will the softwares still be runnable after reinstallation? what are the advantage and disadvantages of installing softwares on root partition and of on home partition? with your answer to the previous questions, what are some reasonable plans for the sizes of root partition and of home partition? Note that I would like to learn programming in C, C++, Java, Python, Lisp, databases under both Ubuntu and Windows, and no games. My laptop has around 230 GB, where I plan to install both Windows and Ubuntu, and reserve 40 GB for Ubuntu (three partitions: swap, root and home), 110 GB for NTFS partition shared between the two OSes, 70 GB for Windows OS partition, and 10 GB that can be added to any of the above partitions. I will change my plan according to your suggestions. Thanks and regards!

  • MonoGame; reliable enough to be accepted on iOS, Win 8 and Android stores?

    - by Serguei Fedorov
    I love XNA; it simplifies rendering code to where I don't have to deal with it, it runs on C# and has very fairly large community and documentation. I would love to be able to use it for games across many platforms. However, I am a little bit concerned about how well it will be met by platform owners; Apple has very tight rules about code base but Android does not. Microsoft's new Windows 8 platforms seems to be pretty lenient but I am not sure oh how they would respond to an XNA project being pushed to the app store (given they suddenly decided to dump it and force developers to use C++/Direct3D). So the bottom line is; is it safe to invest time and energy into a project that runs on MonoGame? In the end, is is possible to see my game on multiple platforms and not be shot down with a useless product?

  • How do you manage frequent software releases to multiple clients?

    - by meeech
    hi we have a cross-platform middleware product which we typically end up customizing/bug fixing on a per client basis. In some cases, providing updates as often as once/twice per week. We have a lot of trouble efficiently managing and releasing the updates to our clients. I've done some digging, but I can't find anything to specifically address this problem. Can anyone share their experiences - how do you deal with this scenario, or do you know of a good software delivery cms? thanks

  • 2D basic map system

    - by Cyril
    i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

  • Should I use XNA (C#) or Java to create a basic game engine?

    - by Xboxking
    My project is to design and build a game engine (in just about 3 months). I've been looking at two options for this game engine, either make it with XNA (and C#) or Java. My experience with XNA/C# is zero to none, however I have been a Java programmer for around 4 years. I've had a little play around with both but I am still not sure what would be best to use (i.e. what would turn out better with my experience). XNA is obviously for making games and I would presume making a game engine would be slightly easier in this - however that said, there are numerous libraries available in Java that could be used for a game engine (such as lwjgl). What would be my best option and ideally produce the best results out of both XNA or Java? For your information, the game engine at the moment is a 2D one and is not too advanced (although I plan to extend it in the future). Thanks in advance for all answers!

  • Is there a global "low resolution" filter for OpenGL?

    - by Ian Henry
    I'm trying to learn a little about OpenGL, so I'm making a simple 2D game (with OpenTK), and so far it's coming along well. I thought it would be fun to give it that, for lack of a better word, retropixelated look of games from the early nineties. I figured it would be an easy thing to do -- simply draw everything at half its normal size and scale up with no anti-aliasing. But I can't find any resources on how to do this. I can set the min/mag filters of my textures to nearest and that works fine for my sprites, but I'm using lots of primitives and I'd like the effect to apply to them as well. The one idea I had was to draw everything at half size, then somehow copy the render buffer to a texture, then render that texture full-size, but I don't know how to do that, and it seems like there must be a better way. Can anyone help me out?

  • Oracle's Integrated Systems Management and Support Experience

    - by Scott McNeil
    With its recent launch, Oracle Enterprise Manager 11g introduced a new approach to integrated systems management and support. What this means is taking both areas of IT management and vendor support and combining them into one integrated comprehensive and centralized platform. Traditional Ways Under the traditional method, IT operational teams would often focus on running their systems using management tools that weren’t connected to their vendor’s support systems. If you needed support with a product, administrators would often contact the vendor by phone or visit the vendor website for support and then log a service request in order to fix the issues. This method was also very time consuming, as administrators would have to collect their software configurations, operating systems and hardware settings, then manually enter them into an online form or recite them to a support analyst on the phone. For the vendor, they had to analyze all the configuration data to recreate the problem in order to solve it. This approach was very manual, uncoordinated and error-prone where duplication between the customer and vendor frequently occurred. A Better Support Experience By removing the boundaries between support, IT management tools and the customer’s IT infrastructure, Oracle paved the way for a better support experience. This was achieved through integration between Oracle Enterprise Manager 11g and My Oracle Support. Administrators can not only manage their IT infrastructure and applications through Oracle Enterprise Manager’s centralized console but can also receive proactive alerts and patch recommendations right within the console they use day-in-day-out. Having one single source of information saves time and potentially prevents unforeseen problems down the road. All for One, and One for All The first step for you is to allow Oracle Enterprise Manager to upload configuration data into Oracle’s secure configuration repository, where it can be analyzed for potential issues or conflicts for all customers. A fix to a problem encountered by one customer may actually be relevant to many more. The integration between My Oracle Support and Oracle Enterprise Manager allows all customers who may be impacted by the problem to receive a notification about the fix. Once the alert appears in Oracle Enterprise Manager’s console, the administrator can take his/her time to do further investigations using automated workflows provided in Oracle Enterprise Manager to analyze potential conflicts. Finally, administrators can schedule a time to test and automatically apply the fix to all the systems that need it. In the end, this helps customers maintain their service levels without compromise and avoid experiencing unplanned downtime that may result from potential issues or conflicts. This new paradigm of integrated systems management and support helps customers keep their systems secure, compliant, and up-to-date, while eliminating the traditional silos between IT management and vendor support. Oracle’s next generation platform also works hand-in-hand to provide higher quality of service to business users while at the same time making life for administrators less complicated. For more information on Oracle’s integrated systems management and support experience, be sure to visit our Oracle Enterprise Manager 11g Resource Center for the latest customer videos, webcast, and white papers.

  • How to Quickly Check If Your Computer Can Run a PC Game

    - by Chris Hoffman
    PC gaming isn’t quite as simple as console gaming. If you have a laptop with weak graphics hardware or an older PC, it’s important to check whether your computer can support a game before you spend your hard-earned cash. Gamers don’t have to upgrade their hardware as often as they used to. Even a gaming PC built years ago should be able to handle the newest games just fine. Laptops not build for gaming and older PCs are a different matter.

  • Forms&Reports upgrade characterset issues

    - by Lukasz Romaszewski
    Hello,This quick post is based on my findings during recent IMC workshops, especially those related to upgrading the Forms 6i/9i/10g applications to Forms 11g platform. The upgrade process itself is pretty straightforward and it basically requires recompiling your Forms application with a latest version of frmcmp tool. For some cases though, especially when you migrate from Forms 6i which is a client-server architecture to a 3-tier web solution (Forms 11g), you need to rewrite some parts of your code to make it run on new platform. The things you need to change range from reimplementing (using webutil library) typical client-site functionality like local IO operation, access to WinAPI, invoking DLLs etc. to changing deprecated or obsolete APIs like RUN_PRODUCT to RUN_REPORT_OBJECT. To automate those changes Oracle provides complete Java API  which allows you to manipulate the code and structure of you modules (JDAPI). To make it even easier we can use Forms Migration Assistant tool (written in Java using JDAPI) which is able to replace all occurrences of old API entries with their 11g equivalents or warn you when the replacement is not possible. You can also add your own replacement definitions in the search_replace.properties file. But you need to be aware of some issues that can be encountered using this tool. First of all if you are using some hard-coded text inside your triggers you may notice that after processing them by the Migration Assistant tool the national characters may be lost. This is due to the fact that you need to explicitly tell Java application (which MA really is) what kind of characterset it should use to read those text properly. In order to do that just add to a script calling MA the following line:  export JAVA_TOOL_OPTIONS=-Dfile.encoding=<JAVA_ISO_ENCODING>  when the particular encoding must match the NLS_LANG in your Forms Builder environment (for example for Polish characterset you need to use ISO-8859-2).Second issue you can encounter related to national charactersets is lack of national symbols in you reports after migration. This can be solved by adding appropriate NLS_LANG entry in your reports environment. Sometimes instead of particular characterset you see "Greek characters" in your reports. This is just default font used by reports engine instead of the one defined in your report. To solve it you must copy fonts definitions from your old environment (e.g. Forms 10g installation) to appropriate directory in new installation (usually AFM folder). For more information about this and other issues please refer to https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=BULLETIN&id=1297012.1at My Oracle Support site. That's all for today, stay tuned for more posts on this topic! Lukasz
