  • How to implment the database for event conditions and item bonuses for a browser based game

    - by Saifis
    I am currently creating a browser based game, and was wondering what was the standard approach in making diverse conditions and status bonuses database wise. Currently considering two cases. Event Conditions Needs min 1000 gold Needs min Lv 10 Needs certain item. Needs fulfillment of another event Status Bonus Reduces damage by 20% +100 attack points Deflects certain type of attack I wish to be able to continually change these parameters during the process of production and operation, so having them hard-coded isn't the best way. All I could come up with are the following two methods. Method 1 Create a table that contains each conditions with needed attributes Have a model named conditions with all the attributes it would need to set them conditions condition_type (level, money_min, money_max item, event_aquired) condition_amount prerequisite_condition_id prerequisite_item_id Method 2 write it in a DSL form that could be interpreted later in the code Perhaps something like yaml, have a text area in the setting form and have the code interpret it. condition_foo: condition_type :level min_level: 10 condition_type :item item_id: 2 At current Method 2 looks to be more practical and flexible for future changes, trade off being that all the flex must be done on the code side. Not to sure how this is supposed to be done, is it supposed to be hard coded? separate config file? Any help would be appreciated. Added For additional info, it will be implemented with Ruby on Rails

  • Are webhosts that require NS instead of a CNAME common?

    - by billpg
    I've just signed up with a webhost (which I prefer not to name) and I'm reasonably happy with it. The only nit was when I was ready to put a site online and I asked the support line to what name I should point my 'www' CNAME to. They responded that they don't do that and I need to set my domain's NS records for the hosting to work. "Why would you ever want to do it that way? Our service to you includes DNS and our servers are probably much better than the one your registrar provides." This was a bit of surprise as all of the other webhosts I've worked with happily support this. I've set up (eg) gallery.myfriend.example for friends by having them configure their DNS to CNAME 'gallery' to the name of a shared server at a webhost and the webhost does name-based hosting for 'gallery.myfriend.example'. (Of course, if the webhost ever tells me I'm being moved from A.webhost.example to B.webhost.example, it would be my responsibility to change where the CNAME points. Really good webhosts would instead create myname.webhost.example for the IP of whichever server my stuff happens to be on, so I'd never have to worry about keeping my CNAME up to date.) Is my impression correct, that most webhosts will happily support a service that begins with a CNAME hosted elsewhere, or is it really more common that webhosts will only provide a service if they control the DNS service too?

  • Are there any real-world cases for C++ without exceptions?

    - by Martin
    In When to use C over C++, and C++ over C? there is a statement wrt. to code size / C++ exceptions: Jerry answers (among other points): (...) it tends to be more difficult to produce truly tiny executables with C++. For really small systems, you're rarely writing a lot of code anyway, and the extra (...) to which I asked why that would be, to which Jerry responded: the main thing is that C++ includes exception handling, which (at least usually) adds some minimum to the executable size. Most compilers will let you disable exception handling, but when you do the result isn't quite C++ anymore. (...) which I do not really doubt on a technical real world level. Therefore I'm interested (purely out of curiosity) to hear from real world examples where a project chose C++ as a language and then chose to disable exceptions. (Not just merely "not use" exceptions in user code, but disable them in the compiler, so that you can't throw or catch exceptions.) Why does a project chose to do so (still using C++ and not C, but no exceptions) - what are/were the (technical) reasons? Addendum: For those wishing to elaborate on their answers, it would be nice to detail how the implications of no-exceptions are handled: STL collections (vector, ...) do not work properly (allocation failure cannot be reported) new can't throw Constructors cannot fail

  • Where to look for challenging jobs with a relaxed atmosphere?

    - by RBTree
    I'm a dev at one of the big-name tech companies. I like the job for many reasons: I do interesting work on a cool product I solve challenging problems and use a lot of high-level skills (quantitative, creative, writing, presenting) It pays well The problem is that I feel I need a more relaxed atmosphere (shorter hours, less performance pressure, and more flexibility), in order to free up time for other pursuits and reduce stress. The ideal would be a job that's around 30-35 hours a week, where there is flexibility to work more or less in a given week. Can anyone suggest where to look for a job like this, where I wouldn't have to sacrifice too much on the above points? (Obviously I would have to sacrifice pay.) My employer does not generally offer part-time employment. The closest thing I can think of is when I did summer internships at my university's CS department. The work was very intellectually challenging, but if I needed to go home a couple hours early or get flexibility on a due date, nobody batted an eyelash. However, I'd like to find out if there are alternatives to academia since from what I've seen the pay there is a gigantic drop from what I'm currently making. I've done freelance development before, but I do like that as an employee of a large company I have a lot of things taken care of for me (e.g. benefits and guaranteed stable employment).

  • Learning OpenGL GLSL - VAO buffer problems?

    - by Bleary
    I've just started digging through OpenGL and GLSL, and now stumbled on something I can't get my head around this one!? I've stepped back to loading a simple cube and using a simple shader on it, but the result is triangles drawn incorrectly and/or missing. The code I had working perfectly on meshes, but was attempting to move to using VAOs so none of the code for storing the vertices and indices has changed. http://i.stack.imgur.com/RxxZ5.jpg http://i.stack.imgur.com/zSU50.jpg What I have for creating the VAO and buffers is this //Create the Vertex array object glGenVertexArrays(1, &vaoID); // Finally create our vertex buffer objects glGenBuffers(VBO_COUNT, mVBONames); glBindVertexArray(vaoID); // Save vertex attributes into GPU glBindBuffer(GL_ARRAY_BUFFER, mVBONames[VERTEX_VBO]); // Copy data into the buffer object glBufferData(GL_ARRAY_BUFFER, lPolygonVertexCount*VERTEX_STRIDE*sizeof(GLfloat), lVertices, GL_STATIC_DRAW); glEnableVertexAttribArray(pos); glVertexAttribPointer(pos, 3, GL_FLOAT, GL_FALSE, VERTEX_STRIDE*sizeof(GLfloat),0); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, mVBONames[INDEX_VBO]); glBufferData(GL_ELEMENT_ARRAY_BUFFER, lPolygonCount*sizeof(unsigned int), lIndices, GL_STATIC_DRAW); glBindVertexArray(0); And the code for drawing the mesh. glBindVertexArray(vaoID); glUseProgram(shader->programID); GLsizei lOffset = mSubMeshes[pMaterialIndex]->IndexOffset*sizeof(unsigned int); const GLsizei lElementCount = mSubMeshes[pMaterialIndex]->TriangleCount*TRIAGNLE_VERTEX_COUNT; glDrawElements(GL_TRIANGLES, lElementCount, GL_UNSIGNED_SHORT, reinterpret_cast<const GLvoid*>(lOffset)); // All the points are indeed in the correct place!? //glPointSize(10.0f); //glDrawElements(GL_POINTS, lElementCount, GL_UNSIGNED_SHORT, 0); glUseProgram(0); glBindVertexArray(0); Eyes have become bleary looking at this today so any thoughts or a fresh set of eyes would be greatly appreciated.

  • Spreading incoming batched data into a real-time stream

    - by pr1001
    I would like to display some events in 'real-time'. However, I must fetch the data from another source. I can request the last X minutes, though the source is updated approximately every 5 minutes. This means that there will be a delay between the most recent data retrieved and the point in time that I make the request. Second, because I will be receiving a batch of data, I don't want to just fire out all the events down a socket once my fetcher has retrieved it: I would like to spread out the events so that they are both accurately spaced amongst each other and in sync with their original occurrences (e.g. an event is always displayed 6 minutes after it actually happened). My thought is to fetch the data every 5 minutes from the source, knowing that I won't get the very latest data. The original data would be then queued to be sent down the socket 7.5 minutes from its original timestamp – that is, at least ~2.5 minutes from when its batch was fetched and at most 7.5 minutes since then. My question is this: is this the best way to approach the problem? Does this problem have any standard approaches or associated literature related to implementation best-practices and edge cases? I am a bit worried that the frequency of my fetches and the frequency in which the source is updated will get out of sync, leading to points where no data will be retrieved from the source. However, since my socket delay is greater than my fetch frequency, the subsequent fetch should retrieve newer data before the socket queue is empty. Is that correct? Am I missing something? Thanks!

  • How to setup Java-Home and Path in Ubuntu 12.04

    - by ur truly friend
    we are new to Ubuntu.Recently we changed my server OS to ubuntu 12.04 from windows 7 . every one have their own login details. one of my college installed Open-Jdk7. I asked him, where you installed JAVA, then he suggested to switch the following directory su root cd /usr/lib/Jvm Totally 3 folders are there in JVM folder. names are. java-1.7.0-openjdk-amd64 java-7-openjdk-amd64 java-7-openjdk-common generally, If you install Java in Windows, we will get 2 folder. 1 folder is for JDKand another points to JRE. but, in Ubuntu we have 3 folders. is it right? for my conformation, whether he installed correctly or not. I open Terminal. I run the following 2 commands javac java -version both commands are working fine. now I want to set-up Java-Home and Path for all users at same place.because everyone is working on Application server. Can anyone explain step-by-step. Thanks.

  • Is StackOverflow making me stupid? [closed]

    - by Ayush Goyal
    Possible Duplicate: When stuck, how quickly should one resort to Stack Overflow? Its good that solution to almost every programming problem is available at my disposal, either someone has asked it before or programming gurus are waiting for me to post it..sometimes its just the matter of seconds after posting the question and someone points out the error-causing-line or proposes alternate (easier, lightweight and efficient) solution. But today it struck me "is this making me dumb?" In good (umm..not so good) old days I used to figure out the source of my problem and then work it out myself, though it used to eat up lot of time but it helped in developing my logical thinking as it used to make an impression in my mind due to which I tend to avoid that situation in future codes. Now, as soon as I encounter a problem I just give it a shot or two and head towards the community. Many times after looking at the solution it turns out that answer was all in front of me..all I needed was to take a break, hover it once and its solved. Both the approaches make me feel guilty, for wasting time when I could have asked and solved it within minutes OR being too lazy to look over it again before posting the code snippet.

  • proper way to creation multiple similiar buttons/panels

    - by JayAvon
    I have the below Code which i tried to do, but it only shows(the minus/plus button) on the last GirdLayout (Intelligence stat): JButton plusButton = new JButton("+"); JButton minusButton = new JButton("-"); statStrengthGridPanel = new JPanel(new GridLayout(1,3)); statStrengthGridPanel.add(minusButton); statStrengthGridPanel.add(new JLabel("10")); statStrengthGridPanel.add(plusButton); statConstitutionGridPanel = new JPanel(new GridLayout(1,3)); statConstitutionGridPanel.add(minusButton); statConstitutionGridPanel.add(new JLabel("10")); statConstitutionGridPanel.add(plusButton); statDexterityGridPanel = new JPanel(new GridLayout(1,3)); statDexterityGridPanel.add(minusButton); statDexterityGridPanel.add(new JLabel("10")); statDexterityGridPanel.add(plusButton); statIntelligenceGridPanel = new JPanel(new GridLayout(1,3)); statIntelligenceGridPanel.add(minusButton); statIntelligenceGridPanel.add(new JLabel("10")); statIntelligenceGridPanel.add(plusButton); I know I can do something like I did for the Panel names(have multiple ones), but I did not want to do that for the Panels in the first place. I am trying to use best practice and not have my code be repetitive. Any suggestions?? The goal is to have 4 stats, to assign points to, with decrement and increment buttons(I decided against sliders). Eventually I will have them have upper and lower limits, decrement the "unused" label, and all of that good stuff, but I just want to not be repetitive. Thanks for any help.

  • Is a "model" branch a common practice?

    - by dukeofgaming
    I just thought it could be a good thing to have a dedicated version control branch for all database schema changes and I wanted to know if anyone else is doing the same and what have the results been. Say that you are working with: Schema model/documentation (some file where you model the database visually to generate the schema source, say MySQL Workbench, with a .mwb file, which is binary) Schema source (a .sql file) Schema-based code generation The normal way we were working was with feature branches, so we would do changes to the model files (the database specific ones), and then have to regenerate points 2 and 3, dealing with the possible conflicts (or even code rewriting). Now say that your workflow goes the same way as the previous item numbering. With a model branch you wouldn't have to reconcile the schema model with binaries in other feature branches, or have to regenerate schema source and regenerate code (which might have human code on top of it). It makes so much sense to me it feels weird not having seen this earlier as a common practice. Edit: I'm counting on branch merges to be the assertions for the model matching the code. I use a DVCS, so I don't fear long-lived branches or scary-looking merges. I'm also doing feature branching.

  • Why doesn't it seem to be any development in the field of 3D VR gear, especially with regard to gaming?

    - by neuviemeporte
    I remember that way back around 1995, there was this big craze with VR in the media, a whole bunch of (mostly mediocre) games labeled as "virtual-reality-interactive-movie (...)" were published. If I recall correctly, the first 3D VR helmet was called VFX-1 and was sold bundled with Descent and some dedicated joystick. I never owned one, and I read just one review which was mostly enthusiastic, but pointed to some weak points, like the eyes getting tired after an hour or so of playing. Then the whole thing basically flickered down and died. I suppose the main reason it wasn't successful was that the hardware of the day was not powerful enough, the VR gear's design wasn't perfected to make it comfortable and natural to use, and the companies that made it failed to market it successfully. What I can't understand is why isn't there any development in the field today. There is some vr-ish hardware mostly targeted at the consoles (Kinect, Wii remote, TrackIR), but all projects of creating some 3d head-mounted display system seem to be in early infancy, appear once in a trade show somewhere and aren't heard of again. I think it could work great with head tracking and some of today's shooters, flight sims (trackIR is nice but the movement scale translation is awkward) and other games with an FPP POV. Is there any technological reason why decent vr headgear can't be made today, or is it just that nobody really cares/everyone is scared to repeat the '90s failure?

  • Combining pathfinding with global AI objectives

    - by V_Programmer
    I'm making a turn-based strategy game using Java and LibGDX. Now I want to code the AI. I haven't written the AI code yet. I've simply designed it. The AI will have two components, one focused in tactics and resource management (create troops, determine who have strategical advantage, detect important objectives, etc) and a individual component, focused in assign the work to each unit, examine its possibilites and move the unit. Now I'm facing an important problem. The map where the action take place is a grid-based map. Each terrain has different movement cost. I read about pathfinding and I think A* is a very good option to determine a good route between two points. However, imagine I have an unit with movement = 5 (i.e, it can move 5 tiles of movement cost = 1). My tactical AI has found an objective at a distance d = 20 tiles (Manhattan distance) from my unit. My problem is the following: the unit won't be able to reach the objective in one turn. So the AI will have to store a list of position and execute them in various turns. I don't know how to solve this. PS. In my unit code, I have a list called "selectionMarks" which stores all the possible places where the unit can go in this turn. This places are calculed recursively using a "getSelectionMarks" function. Any help is appreciated :D

  • Is it bad to be the only person supporting software you have developed?

    - by trpt4him
    My employer has a need for a web-based application to manage and share data within the department, with approximately 50-75 possible users. I feel I have the ability to write it for them. I would likely use Python/Django with a MySQL database, so it would be open source. However, I'm the only IT person in my department (our larger organization has a separate IT support staff with which I often work, but not for web development). I want to develop this application, but if I leave in 1-2 years, and someone else has to come in after me and support it, will this be seen as a bad decision? This is assuming all the obvious points -- I will write documentation, I will comment my code, and I will strive to follow good application design principles. But will that be enough? In principle, is it acceptable for one person to develop and support an entire web application? Is this a "do first, then show and ask" kind of situation, or should I be certain it will be adopted by everyone involved first?

  • Constituent Experience Counts In Public Sector

    - by Michael Seback
      Businesses and government organizations are operating in an era of the empowered customer where service  and communication channels are challenged every day.  Consumers in the private sector have high expectations from purchasing gifts online, reading reviews on social sites, and expecting the companies they do business with to know and reward them.   In the Public Sector, constituents also expect government organizations to provide consistent and timely service across agencies and touch points.  Examples include requesting critical city services, applying for social assistance or reviewing insurance plans for a health insurance exchange. If an individual does not receive the services they need at the right time and place, it can create a dire situation – involving housing, food or healthcare assistance. Government organizations need to deliver a fast, reliable and personalized experience to constituents. Look at a few recent statistics from a Government focused survey: How do you define good customer service? 70 % improved services, 48% shortest time to provide information, 44% shortest time to resolve complaints What are ways/opportunities to improve customer service? 69% increased collaboration across agencies and 41% increased customer service channels Are you using data collected to make informed decisionsto improve customer service efforts? 39% data collection is limited, not used to improve decision making Source: Re-Imagining Customer Service in Government, 2012 Click here to see the highlights.  Would you like to get started – read Eight Steps to great constituent experiences for government.

  • Could someone explain why my world reconstructed from depth position is incorrect?

    - by yuumei
    I am attempting to reconstruct the world position in the fragment shader from a depth texture. I pass in the 8 frustum points in world space and interpolate them across fragments and then interpolate from near to far by the depth: highp float depth = (2.0 * CameraPlanes.x) / (CameraPlanes.y + CameraPlanes.x - texture( depthTexture, textureCoord ).x * (CameraPlanes.y - CameraPlanes.x)); // Reconstruct the world position from the linear depth highp vec3 world = mix( nearWorldPos, farWorldPos, depth ); CameraPlanes.x is the near plane CameraPlanes.y is the far. Assuming that my frustum positions are correct, and my depth looks correct, why is my world position wrong? (My depth texture is of format GL_DEPTH_COMPONENT32F if that matters) Thanks! :D Update: Screenshot of world position http://imgur.com/sSlHd So you can see it looks nearly correct. However as the camera moves, the colours (positions) change, which they shouldnt. I can get this to work, if I do the following: Write this into the depth attachment in the previous pass: gl_FragDepth = gl_FragCoord.z / gl_FragCoord.w / CameraPlanes.y; and then read the depth texture like so: depth = texture( depthTexture, textureCoord ).x However this will kill the hardware z buffer optimizations.

  • The most efficent ways for drawing lines all day long with OpenGL

    - by nkint
    I'd like to put a computer screen that is running an OpenGL programs in a room. It has to run all day long (not in the night). I'd like to draw lines that are slowly fading in the background. The setting is simple: a uniform color background (say, black) and colored lines (say, white) that are slowly fading out. With slowly I mean.. hours. Say that the first line I draw is with alpha 255 (fully visible), after one hours is 240. After 10 hours is 105. One line could have 250 points and there will be like 300 line in one day. For now I have done a prototype with very rudimentary method like: glBegin( GL_LINE_STRIP ); iterator = point_list.begin(); for (++iterator, end = point_list.end(); iterator != end; ++iterator) { const Vec3D &v = *iterator; glVertex2f(v.x(), v.y()); } glEnd(); More efficient method?

  • String Conversion to Char for Java Game

    - by Jen
    Is there someone who could help me achieve the following points on this problems? I can't seem to get it. I tried using toCharArray and Scanner to achieve this, but it doesn't work, nor do I know how to make this things possible for my word game. :( · Get a popular name of person, place, verse, saying or event from the user. This may have a single or multiple words in it. · Create a copy of this string to an array where each letter is replaced with a hyphen (-) and each space is replaced with an underscore (_). Symbols and numbers will remain shown. · The program then asks a letter from the user. If the letter is in the inputted string, then it should be shown on the array at the same position it is shown in the string. Meaning, the letter replaces the hyphen (-) at the correct position of the array. · The program again prompts for a letter from the user and replaces the hyphen (-) of the array if it exists on the inputted string. This will be repeatedly done until such time each hyphen (-) is replaced with the correct letter. · If the user inputs an invalid letter, that is, a letter that does not exist on the inputted string, then the program should inform the user. If this happens 3 times while there is still at least one hyphen on the array, then the program should inform the user that he lost the game and showing him the whole correct string. · If the user completes the game, meaning, all hyphens have been replaced with the correct letters; then the program should congratulate the user for a job well done.

  • How do I separate model positions from view positions in MVC?

    - by tieTYT
    Using MVC in games (as opposed to web apps) always confuses me when it comes to the view. How am I supposed to keep the model agnostic of how the view is presenting things? I always end up giving the Model a position that holds x and y but invariably, these values end up being in units of pixels and that feels wrong. I can see the advantage* of avoiding that but how am I supposed to? This idea was suggested: Don't think of it in units of pixels, think of them in arbitrary distance units that just happen map to pixels at a 1:1 ratio. Oh, the resolution is half of what it was? We are now taking the x/y coordinates at 50% value for screen display, and your spells casting range is still 300 units long, which now is 150 pixels. But those numbers conveniently work out. What do I do if the numbers divide in such a way that I get decimal places? Floating points are unsafe. I think allowing decimal places would eventually cause really weird bugs in my game. *It'd let me write the model once and write different views depending on the device.

  • Correct way to use Farseer Physics in XNA

    - by user1640602
    I am using Farseer Physics for my 2D sidescroller game and I'm not sure how to proceed with it. I currently have a Sprite class (handles nothing but graphics), a GameObject class (contains specific object info like hit points), a World object which contains the list of Bodies, and a Level object which contains all of these objects. Originally I was trying to keep track of the Sprites, GameObjects, and Bodies separately because I felt that would provide loose coupling but it quickly became a headache. So my new idea was to add a Sprite member to the GameObject class but I'm still not sure how to maintain the Bodies because they have to communicate with GameObject. Specifically, my issue is this: The position of the Body is used to draw the Sprite inside of the Level. In order to do that I would have to maintain a link between GameObjects and Bodies. Is this correct or is there a better way to architect my game? If any of this is unclear please ask and I'll try to clarify. Thank you in advance for any help.

  • Ubuntu Boot Slow - Late Drive Access

    - by Mo2
    So I just installed Ubuntu on a brand new Samsung 840 Pro SSD and have noticed that it is slower than expected. The LED access light doesn't start blinking until after 20 seconds or so have passed, after which the boot up seems to actually start. Does anyone have any ideas as to why this is happening? I have Windows 7 installed on a separate SSD and use Windows Loader as the main loader. Windows Loader points to GRUB2, from which I then start Ubuntu up. The 20 seconds count that I mentioned earlier starts AFTER I select Ubuntu 14.04.1 from the GRUB2 menu. Any help is appreciated. EDIT: I forgot to mention that I have only one partition for / and /home. I intend on using a shared NTFS drive for my documents and other personal files, so I had no need for the /home. I did not make a /swap since I have 12 GB of RAM. I also did not make a /boot since I was told that it's not really necessary in my case.

  • Does F# kill C++?

    - by MarkPearl
    Okay, so the title may be a little misleading… but I am currently travelling and so have had very little time and access to resources to do much fsharping – this has meant that I am right now missing my favourite new language. I was interested to see this post on Stack Overflow this evening concerning the performance of the F# language. The person posing the question asked 8 key points about the F# language, namely… How well does it do floating-point? Does it allow vector instructions How friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? Does it have capacity for distributed memory processors, for example Cray? What features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Now, I don’t have much time to look into a decent response and to be honest I don’t know half of the answers to what he is asking, but it was interesting to see what was put up as an answer so far and would be interesting to get other peoples feedback on these questions if they know of anything other than what has been covered in the answer section already.

  • can't get a good install:11.10 server

    I screwed up my partitioning aparently tring to get lvm and raid1 going. the machine is an intel dual core dt with 2 gig of ram and 2 sata drives, one 250g and the other 500g. This a build for my school in n.e. Thailand. we have 20+ clients now, a website, email. Our old server is dying fast and we are going to add another 12 stations next week. I really need some help here! 1. have onboard gigabit ethernet that aparently uses same driver as realtek 811c. I installed a pcie gigabit card also 811c. At several points the eth0 has accessed the internet fine, but the eth1 will not communicate. 2. I saw a "fix" for this online which from root: rmmod r8169. this imediately killed the working onboard card. 3.I tried to re-install 11.10 figuring that would re-install r8169. However I messed something up in my partitioning and can't get a clean boot now. 6. so I think after 12 re-installs or so and 2 days. I can get through it right if I can start over with clean drives, but I can't figure out how to empty them out what with soft raid and lvm partitions. seems like i've had it going well and then trying to fix that one little problem, i go backwards.Please help! please send email.-thanks

    - by Adam Naylor
    I've been adapting the NeHe ogl/win32 code to be more object orientated and I don't like the way some of the calls are structured. The example has the following pseudo structure: Register window class Change display settings with a DEVMODE Adjust window rect Create window Get DC Find closest matching pixel format Set the pixel format to closest match Create rendering context Make that context current Show the window Set it to foreground Set it to having focus Resize the GL scene Init GL The points in bold are what I want to move into a rendering class (the rest are what I see being pure win32 calls) but I'm not sure if I can call them after the win32 calls. Essentially what I'm aiming for is to encapsulate the Win32 calls into a Platform::Initiate() type method and the rest into a sort of Renderer::Initiate() method. So my question essentially boils down to: "Would OpenGL allow these methods to be called in this order?" Register window class Adjust window rect Create window Get DC Show the window Set it to foreground Set it to having focus Change display settings with a DEVMODE Find closest matching pixel format Set the pixel format to closest match Create rendering context Make that context current Resize the GL scene Init GL (obviously passing through the appropriate window handles and device contexts.) Thanks in advance.

  • How can I read a portion of one Minecraft world file and write it into another?

    - by RapierMother
    I'm looking to read block data from one Minecraft world and write the data into certain places in another. I have a Minecraft world, let's say "TemplateWorld", and a 2D list of Point objects. I'm developing an application that should use the x and y values of these Points as x and z reference coordinates from which to read constant-sized areas of blocks from the TemplateWorld. It should then write these blocks into another Minecraft world at constant y coordinates, with x & z coordinates determined based on each Point's index in the 2D list. The issue is that, while I've found a decent amount of information online regarding Minecraft world formats, I haven't found what I really need: more of a breakdown by hex address of where/what everything is. For example, I could have the TemplateWorld actually be a .schematic file rather than a world; I just need to be able to read the bytes of the file, know that the actual block data starts always at a certain address (or after a certain instance of FF, etc.), and how it's stored. Once I know that, it's easy as pie to just read the bytes and store them.
