  • How do I obtain a code point integer from a 1 to 4 byte UTF-8 encoded sequence in Windows?

    - by Patrick Niedzielski
    Hello, I am Patrick Niedzielski, a programmer for the Free Software 3D adventure game Humm and Strumm. I'm working on a minimal Unicode character class in C++. I currently have an array of four bytes representing a UTF-8 sequence. On GNU/Linux, I can just convert to UTF-32 with iconv(), but on Windows, I cannot do this. Is it possible to convert the array to a single code point? Thanks, Patrick

  • Does mixing Quartz and OpenGL-ES cause big performance degrade??

    - by Eonil
    I have a plan to make a game using OpenGL for 3D world view, and CALayer(or UIView) for HUD UI. It's easy to imagine performance degrade from mixing them, but the document which mention this impact disappeared: http://developer.apple.com/iphone/library/technotes/tn2008/tn2230.html I cannot find the document on current version of SDK reference. And I got this document: http://gamesfromwithin.com/gdc-2010-the-best-of-both-worlds-using-uikit-with-opengl If you experienced about this, please let me know about performance impact on current SDK.

  • How does Dijkstra's Algorithm and A-Star compare?

    - by KingNestor
    I was looking at what the guys in the Mario AI Competition have been doing and some of them have built some pretty neat Mario bots utilizing the A* (A-Star) Pathing Algorithm. (Video of Mario A* Bot In Action) My question is, how does A-Star compare with Dijkstra? Looking over them, they seem similar. Why would someone use one over the other? Especially in the context of pathing in games?

  • Android VideoView LinearLayout.LayoutParams

    - by Chris
    I am playing a video using VideoView in my app. When I play it on Droid with linearlayout params FILL_PARENT, FILL_PARENT, it plays well. The same params do not work well for a myTouch. What params can I use that will work well with most devices? Thanks Chris

  • From a 3D modeler to an iPhone app - what are best practices?

    - by bonkey
    I am quite new in 3D programming on iPhone and I would like to ask for hints about organizing a work between designers and programmers on that platform. Most of all: what kind of tools, libraries or plugins cooperate the best on both sides. Although I consider the question as looking for general best-practices advice I would like to find a solution for my current situation which I describe further, too. I've already done some research and found following libraries: SIO2 Khronos OpenGL ES 1.x SDK for PowerVR MBX Unity3D Oolong Game Engine I've checked modellers or plugins to them giving output formats readable by those tools: obj2opengl Wavefront OBJ to plain header file converter Blender with SIO2 exporter iphonewavefrontloader Cheetah3D PVRGeoPOD for 3DS / Maya Unfortunately I still have no clear vision how to combine any of that tools to get a desinger's work in an application. I look for a way of getting it in the most possible complete way: models, lights, scenes, textures, maybe some simple animations (but rather no game-like physics), but I still got nothing. And here comes my situation: I would like to find right way to present few (but quite complicated) models from a single scene. The designers mostly use 3DS Max 9, sometimes 10 (which partly prevents using PVRGeoPOD) and are rather reluctant to switch to something else but if there's no other choice I suppose it would be possible. The basic rule I've already found in some places "use Wavefront OBJ" not always works. I haven't got any acceptable results with production files, actually. The only things worked fine were some mere examples. Some of my models did imported incomplete, sometimes exporters hung or generated enormous files not really useful on an iPhone, sometimes enabling textures (with GL_TEXTURE_2D) just crashed an app. I know it might be a problem with too complicated models or my mistakes coming from inexeperience but I am not able to find any guidelines for that process to have streamlined cooperation with designers. I am even willing to write some things from scratch in pure OpenGL-ES if it's necessary, but I would like to avoid what might be avoided and get the most from the model files. The best would be the effect I saw on some SIO2 tutorials: export, build & go. But at that moment I've got only "import, wrong", "import, where are textures?", "import, that almost looks fine, export, hang" and so on... Is it really so much frustrating or I am just missed something obvious? Can anybody share his/her experience in that field and tell what kind of software uses for "making things happen"?

  • Ruby Abstract Class Design

    - by MattDiPasquale
    I'm creating a video game. It has Characters & Items. Since I want Characters & Items to each have a name, should I make another class called NamedObjects with just a name field and have Characters & Items extend that? Or is that going overboard?

  • Detect marker with opencv and python

    - by Mitch
    Hi im trying to detect a marker in a webcam video feed and overlay it with a 3d object - pretty much exactly like this: http://www.morethantechnical.com/2009/06/28/augmented-reality-with-nyartoolkit-opencv-opengl/ i know artoolkit is the best module for this, but i was hoping to just use opencv in python since i dont know nearly enough c/c++ to be able to use artoolkit. im hoping someone will be able to get me on the right track towards detecting the marker and determining its location and orientation etc since i have no idea how best to go about this or what functions i should be using thanks mitch

  • Will Python 3.0's backwards-incompatibility affect adoption?

    - by George Stocker
    I visited Slashdot this morning to find out that Python 3.0 has been released. I know C# and Perl, but have wanted to learn Python for some time, especially after I saw its ease of use to create useful tools, not to mention its use in game scripting. My question is, how does the intentionally backwards-incompatible release of Python 3.0 affect adoption, and should I learn Python 2? Or should I take the dive and learn Python 3.0 first, and wait for the libraries to be ported?

  • Anyone knows which networking package contains winlive.h ?

    - by Reza
    I am dealing with a c++ small game solution which contains references to winlive.h header. I'm sure it is part of a networking package, but haven't been able to track it down. It is not in windows sdk or platform sdk. Anyone may have have seen this before and can point me in the right direction? thanks

  • What does it call in GWT to make 2 UI consistent?

    - by DucDigital
    I saw a video of Google I/O and found an example of GWT UI being very consistent between clients. Which you can save, add, drag and drop in almost real time between clients. I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information? Thank you very much

  • How do you solve the 15-puzzle with A-Star or Dijkstra's Algorithm?

    - by Sean
    I've read in one of my AI books that popular algorithms (A-Star, Dijkstra) for path-finding in simulation or games is also used to solve the well-known "15-puzzle". Can anyone give me some pointers on how I would reduce the 15-puzzle to a graph of nodes and edges so that I could apply one of these algorithms? If I were to treat each node in the graph as a game state then wouldn't that tree become quite large? Or is that just the way to do it?

  • NoHostAvailableException With Cassandra & DataStax Java Driver If Large ResultSet

    - by hughj
    The setup: 2-node Cassandra 1.2.6 cluster replicas=2 very large CQL3 table with no secondary index Rowkey is a UUID.randomUUID().toString() read consistency set to ONE Using DataStax java driver 1.0 The request: Attempting to do a table scan by "SELECT some-col from schema.table LIMIT nnn;" The fail: Once I go beyond a certain nnn LIMIT, I start to get NoHostAvailableExceptions from the driver. It reads like this: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /10.181.13.239 ([/10.181.13.239] Unexpected exception triggered)) at com.datastax.driver.core.exceptions.NoHostAvailableException.copy(NoHostAvailableException.java:64) at com.datastax.driver.core.ResultSetFuture.extractCauseFromExecutionException(ResultSetFuture.java:214) at com.datastax.driver.core.ResultSetFuture.getUninterruptibly(ResultSetFuture.java:169) at com.jpmc.es.rtm.storage.impl.EventExtract.main(EventExtract.java:36) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /10.181.13.239 ([/10.181.13.239] Unexpected exception triggered)) at com.datastax.driver.core.RequestHandler.sendRequest(RequestHandler.java:98) at com.datastax.driver.core.RequestHandler$1.run(RequestHandler.java:165) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) Given: This is probably not the most enlightened thing to do to a large table with millions of rows, but this is how I learn what not to do, so I would really appreciate someone who could volunteer how this kind of error can be debugged. For example, when this happens, there are no indications that the nodes in the cluster ever had an issue with the request (there is nothing in the logs on either node that indicate any timeout or failure). Also, I enabled the trace on the driver, which gives you some nice autotrace (ala Oracle) info as long as the query succeeds. But in this case, the driver blows a NoHostAvailableException and no ExecutionInfo is available, so tracing has not provided any benefit in this case. I also find it interesting that this does not seem to be recorded as a timeout (my JMX consoles tell me no timeouts have occurred). So, I am left not understanding WHERE the failure is actually occurring. I am left with the idea that it is the driver that is having a problem, but I don't know how to debug it (and I would really like to). I have read several posts from folks that state that query'g for resultSets 10000 rows is probably not a good idea, and I am willing to accept this, but I would like to understand what is causing the exception and where the exception is happening. FWIW, I also tried bumping the timeout properties in the cassandra.yaml, but this made no difference whatsoever. I welcome any suggestions, anecdotes, insults, or monetary contributions for my registration in the house of moron-developers. Regards!!

  • Fastest python/C++ multimedia library

    - by Matthew Mitchell
    I'm using pyglet for my OpenGL based game but is it the fastest library out there which has a python wrapper? I could create a C++ extension and use any C++ multimedia library. Are there any C++ libraries that are worth investing time into or is it not worth the extra work? Thank you.

  • What does "prototyping" mean in practice?

    - by prot
    When I recently asked about the uses of Ruby someone told me it was good for prototyping. I basically know what that means, quickly get the very base of your app up and working, see if there are conceptual problems and then add the rest. Am I right with how I understand prototyping? What would be a concrete example of prototyping a Snake game in Ruby or any other language?

  • Nonblocking texture upload on iPhone and other OpenGL ES platforms

    - by spurserh
    Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. A below answer suggests that glTexImage2D is always blocking, even if texture object referenced does is not used for any drawing. Is there a way to do a nonblocking texture upload with OpenGL ES (any version)? Thank you very much, Sean
