• Personal Development : Time, Planning , Repairs & Maintenance

  - by Rajesh Pillai

  Personal Development : Time, Planning, Repairs & Maintenance These are just my thoughts, but some you may find something interesting in it. Please think over it. We may know many things, but still we always keeps procrastinating it. I have written this as I have heard many people coming back and saying they don’t have time to do things they like. These are my thoughts buy may be useful to someone else too. Certain things in life needs periodic repairs and maintenance. To cite some examples , your CAR, your HOUSE, your personal laptop/desktop, your health etc. Likewise there are certain other things in professional life that requires repair/ maintenance /or some kind of polishing, so that you always stay on top of it. But they are not always obvious. Some of them are - Improving your communication skills - Increasing your vocabulary - Upgrading your technical skills - Pursuing your hobby - Increasing your knowledge/awareness etc… etc… And then there are certain things that we are always short of…. one is TIME. We all know TIME is one of the most precious things in life and yet we all are very miserable at managing it. Remember you can only manage it and not control it. You can only control which you own or which you create. In theory time is infinite. So, there should be abundant of it. But remember one thing, you know this, it’s not reversible. Once it has elapsed you cannot live it again. Think over it. So, how do find that golden 25th hour every day. To find the 25th hour you need to reflect back on your current daily activities. Analyze them and see where you are spending most of your time and is it really important. Even the 8 hours that you spent in the office, is it spent fruitfully. At the end of the day is the 8 precious hour that you spent was worth it. Just reflect back on your activities. Did you learn something? If yes did you make a point to NOTE IT. If you didn’t NOTED it then was the time you spent really worth it. Just ponder over it. Some calculations of your daily activities where most of the time is spent. Let’s start (in no particular order though) - Sleep (6.5 hours) [Remember you only require 6 good hours of sleep every day]. Some may thing it is 8, but it’s a myth.   o To achive 6 hours of sleep and be in good health you can practice 15 minutes of daily meditation. So effectively you can    round it to 6.5 hours. - Morning chores(2 hours) : Some may need to prepare breakfast and all other things. - Office commuting (avg. to and fro 3 hours) - Office Work (avg 9.5 hours) Total Hours: 21 hours effective time which is spent irrespective of what you do. There may be some variations here and there. Still you have 3 hours EXTRA. Where do these 3 hours go? If you can find it, then you may get that golden 25th hour out of these 3 hours. Let’s discount 2 hours for contingencies, still you have 1 hour with you. If you can’t find it then you are living a direction less life. As you can see, the 25th Hour lies within the 24 hours of the day. It’s upto each one of us to find and make use of it. Now what can you do with that 25th hour i.e. 1 hour extra of your life. Imagine the possibility. Again some calculations 1 hour daily * 30 days = 30 hours every month 30 hours pm * 12 month = 360 hours every year. 360 hours every year seems very promising. Let’s add some contingencies, say, let’s be optimistic and say 50 % contingency. Still you have 180 hours every year. That leaves with 30 minutes every day of extra time. That’s hell a lot of time, if you could manage it. These may sound like a high talk [yes, it is, unless you apply these simple rules and rationalize your everyday living and stop procrastinating]. NOTE: I haven’t taken weekend, holidays and leaves into account. So, that leaves us with a lot of buffer time. You can meet family friends, relatives, other tasks, and yet have these 180 pure hours of joy every year. Do whatever you want to do with it. So, how important is this 180 hours per year to you? Just think over it. You may use it the way you like - 50 hours [pursue your hobby like drawing, crafting, learn dance, learn juggling, learn swimming, travelling hmm.. anything you like doing and you didn’t had time to do it.] - 30 hours you can learn a new programming language or technology (i.e. you can get comfortable with it) - 50 hours [improve existing skills] - 20 hours [improve you communication skill]. Do some light reading. - 30 hours [YOU DECIDE WHAT TO DO]? So, if you had done this for one year you would have learnt a new programming language, upgraded existing skills, improved you communication etc.. If you had done this for two years.. imagine the level of personal development or growth which you may have attained….. If you had done this for three years….. NOW I think I don’t need to mention this… So, you still have TIME, as they say TIME is infinite. So, make judicious use of this precious thing. And never ever comeback saying “I don’t have time”. So, if you are RICH in TIME, everything else will be automatically taken care of, as those things may just be a byproduct of how you spend your time… So, happy TIMING your TIME everyday.

• Technical development decision for my newly established software company

  - by test test

  I have a new software company where I am planning to develop CRM system. So I have settled down on the technological approach I am going to use:- I will use an open source Java-based CRM engine. I will use a third party reporting tool named JasperReports for providing reports capabilities for the CRM. I will develop the interface and any customization which the customer might ask for using asp.net mvc framework since my knowledge and experience are based on asp.net. And I will use the CRM API to integrate my asp.net web application with the Java-based CRM. I have developed a simple demo which integrate these three main components (CRM engine, asp.net application and the reporting tool) and they worked well. But I am afraid of the following risk that I might face if I go with the above approach: I should hire developers with different skills and experience: Developers with Java skills to be able to modify the Java-based CRM and writing plug-ins -when needed- to extend the CRM capabilities. Other developers with asp.net skills to be able to build the application such as application forms, the portal from where users will be able to start the CRM processes, searching capabilities, etc. So might the above point raise some risks when I start hiring a new team and start building the CRM application, OR I am on the right track at this early stage?

• Monogame - Shader parameters missing

  - by Layoric

  I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter. I'm not well versed writing shaders, so this might be caused by a more obvious problem. I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Shader code below #include "PPVertexShader.fxh" float2 lightScreenPosition; float4x4 matVP; float2 halfPixel; float SunSize; texture flare; sampler2D Scene: register(s0){ AddressU = Clamp; AddressV = Clamp; }; sampler Flare = sampler_state { Texture = (flare); AddressU = CLAMP; AddressV = CLAMP; }; float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0 { texCoord -= halfPixel; // Get the scene float4 col = 0; // Find the suns position in the world and map it to the screen space. float2 coord; float size = SunSize / 1; float2 center = lightScreenPosition; coord = .5 - (texCoord - center) / size * .5; col += (pow(tex2D(Flare,coord),2) * 1) * 2; return col * tex2D(Scene,texCoord); } technique LightSourceMask { pass p0 { VertexShader = compile vs_4_0 VertexShaderFunction(); PixelShader = compile ps_4_0 LightSourceMaskPS(); } } I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue? As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine. Any help would be appreciated.

• SQL SERVER – How to an Add Identity Column to Table in SQL Server

  - by Pinal Dave

  Here is the question I received on SQLAuthority Fan Page. “How do I add an identity column to Table in SQL Server? “ Sometime the questions are very very simple but the answer is not easy to find. Scenario 1: If you are table does not have identity column, you can simply add the identity column by executing following script: ALTER TABLE MyTable ADD ID INT IDENTITY(1,1) NOT NULL Scenario 2: If your table already has a column which you want to convert to identity column, you can’t do that directly. There is a workaround for the same which I have discussed in depth over the article Add or Remove Identity Property on Column. Scenario 3: If your table has already identity column and you can want to add another identity column for any reason – that is not possible. A table can have only one identity column. If you try to have multiple identity column your table, it will give following error. Msg 2744, Level 16, State 2, Line 2 Multiple identity columns specified for table ‘MyTable‘. Only one identity column per table is allowed. Leave a comment if you have any suggestion.

• Partner Infoline & Service Portal

  - by uwes

  As an EMEA-wide team we're supporting the daily work of our partners. Our team consists of 24 sales consultants, one third is specialized on the Partner Infoline. Partner Infoline's main focus is to deliver actively and reactively technical pre sales knowledge about the Oracle hardware portfolio to our partners.With infoline we assist our partners in their daily work, furthermore we help to educate our partners to be self sufficient in all aspects and questions about hardware configurations and hardware quotes. For our Infoline Service we use a ticketing system called Service Portal which is widely used within Oracle and delivers a good and stable functionality and availability. Our Infoline-Service provides answers to questions concerning technical pre-sales matters that are related to hardware and the corresponding hardware related software.* You can address these types of questions by sending them to our mailing list: [email protected] The serviceportal will send you an auto-reply including a unique reference number, which will be the identification for your request until it is closed. Depending on the complexity of the request, it might be necessary to forward it to our specialists (servers, storage, tape, Solaris etc.) located whole over Europe. In order to make the whole process smooth here are some recommendations: write your request in English; saves translation-time, when it has to be forwarded to the specialists stating clearly in the title your interest area, like for example "memory in M4000 server". one request/one subject; makes it easier to maintain and keep the correspondence clear and simple. The rule of the service is to provide an answer quick, which means the vast majority of the requests are answered within a couple of hours. However please keep in mind that some requests may need extra work by involving the appropriate person within Europe or even in US. Therefore there is no official SLA for this service. * This excludes Oracle "classic" products and post-sales support. The latter should still be addressed through MOS (http://support.oracle.com)

• Emacs: methods for debugging python

  - by Tom Willis

  I use emacs for all my code edit needs. Typically, I will use M-x compile to run my test runner which I would say gets me about 70% of what I need to do to keep the code on track however lately I've been wondering how it might be possible to use M-x pdb on occasions where it would be nice to hit a breakpoint and inspect things. In my googling I've found some things that suggest that this is useful/possible. However I have not managed to get it working in a way that I fully understand. I don't know if it's the combination of buildout + appengine that might be making it more difficult but when I try to do something like M-x pdb Run pdb (like this): /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ Where .../bin/python is the interpreter buildout makes with the path set for all the eggs. ~/bin/pdb is a simple script to call into pdb.main using the current python interpreter HellooKitty:hydrant twillis$ cat ~/bin/pdb #! /usr/bin/env python if __name__ == "__main__": import sys sys.version_info import pdb pdb.main() HellooKitty:hydrant twillis$ .../bin/devappserver is the dev_appserver script that the buildout recipe makes for gae project and .../parts/hydrant-app is the path to the app.yaml I am first presented with a prompt Current directory is /Users/twillis/bin/ C-c C-f Nothing happens but HellooKitty:hydrant twillis$ ps aux | grep pdb twillis 469 100.0 1.6 168488 67188 s002 Rs+ 1:03PM 0:52.19 /usr/local/bin/python2.5 /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ twillis 477 0.0 0.0 2435120 420 s000 R+ 1:05PM 0:00.00 grep pdb HellooKitty:hydrant twillis$ something is happening C-x [space] will report that a breakpoint has been set. But I can't manage to get get things going. It feels like I am missing something obvious here. Am I? So, is interactive debugging in emacs worthwhile? is interactive debugging a google appengine app possible? Any suggestions on how I might get this working?

• deWitters Game loop in libgdx(Android)

  - by jaysingh

  I am a beginner and I want a complete example in LibGDX for android(Fixed time game loop) how to limit the framerate to 50 or 60. Also how to mangae interpolation between game state with simple example code e.g. deWiTTERS Game Loop: @Override public void render() { float deltaTime = Gdx.graphics.getDeltaTime(); Update(deltaTime); Render(deltaTime); } libgdx comments:- There is a Gdx.graphics.setVsync() method (generic = backend-independant), but it is not present in 0.9.1, only in the Nightlies. "Relying on vsync for fixed time steps is a REALLY bad idea. It will break on almost all hardware out there. See LwjglApplicationConfiguration, there's a flag in there that let s use toggle gpu/software vsynching. Play around with it." (Mario) NOTE that none of these limit the framerate to a specific value... if you REALLY need to limit the framerate for some reason, you'll have to handle it yourself by returning from render calls if xxx ms haven't passed since the last render call. li

• Stupid Geek Tricks: Change Your IP Address From the Command Line in Linux

  - by Taylor Gibb

  Almost everybody can figure out how to change their IP address using an interface, but did you know you can set your network card’s IP address using a simple command from the command line? Changing Your IP From the Command Line in Linux Note: This will work on all Debian based Linux Distro’s. To get started type ifconfig into the terminal and hit enter, take note of the name of the interface that you want to change the settings for. To change the settings, you also use the ifconfig command, this time with a few parameters: sudo ifconfig eth0   192.168.0.1 netmask 255.255.255.0 That’s about all all you need to do to change your IP, of course the above command assumes a few things: The interface that you want to change the IP for is eth0 The IP you want to give the interface is 192.168.0.1 The Subnet Mask you want to set for the interface is 255.255.255.0 If you run ifconfig again you will see that your interface has now taken on the new settings you assigned to it. If you wondering how to change the Default Gateway, you can use the route command. sudo route add default gw 192.168.0.253 eth0 Will set your Default Gateway on the eth0 interface to 192.168.0.253. To see your new setting, you will need to display the routing table. route -n That’s all there is to it.

• How to Boot a VMware Virtual Machine from a USB Drive

  - by Usman

  Do you have an OS installed on your USB thumb drive? Booting from it in a VM is now possible, you’ll just have to use a simple trick to get it to work. Last week we showed you how to put Ubuntu on a USB drive in a separate partition, and we also discussed working with VMware Player (our favourite VM Client). But have you ever tried booting from a USB drive in VMWare? It doesn’t allow doing so, but we will force it to boot from a USB, with a bit of old geekery. If you remember, we have showed you how to boot from a USB drive even if your old PC doesn’t allow booting from one. That’s right, using Plop Boot Manager. All we need to do is to load the Plop ISO in VMware, attach and enable the USB drive in VMware, and finally select the USB option in Plop Boot Manager to boot from the USB. So, visit the Plop boot manager download site. HTG Explains: When Do You Need to Update Your Drivers? How to Make the Kindle Fire Silk Browser *Actually* Fast!

• My first encounter with SmartAssembly

  - by Peter Larsson

  Let me start by writing I am a supreme VB6 programmer, but I have very little experience with VB.Net, so I think I still need some more time learning SmartAssembly. SmartAssembly make obfuscating and merging dll files a piece of cake! With it's simple, straight forward and clean GUI I did make my tests work. With other obfuscators like Xenocode, Salamander etc which lets you (and in some cases forces you) control more advanced settings, you really have to know what you are doing. Especially when it comes to protecting code that uses external dependencies. My most annoying experience is that if you start checking radio buttons and activating different obfuscating features in SmartAssembly, you will end up breaking your working code as well, if you like me is not that experienced and don't know what you’re doing. SmartAssembly have some troubleshooting information on their website which explains why the application will fail in some scenarios. So why not extend these checks in some deeper analyzing stage on the dll's? By doing that I think more people could get fully functional dll's out of the box instead of trying different settings and then test the protected dll and see if it's working or not. //Peter

• 2D Side Scrolling game and "walk over ground" collision detection

  - by Fire-Dragon-DoL

  The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

• Find The Bug

  - by Alois Kraus

  What does this code print and why?             HashSet<int> set = new HashSet<int>();             int[] data = new int[] { 1, 2, 1, 2 };             var unique = from i in data                          where set.Add(i)                          select i;   // Compiles to: var unique = Enumerable.Where(data, (i) => set.Add(i));             foreach (var i in unique)             {                 Console.WriteLine("First: {0}", i);             }               foreach (var i in unique)             {                 Console.WriteLine("Second: {0}", i);             }   The output is: First: 1 First: 2 Why is there no output of the second loop? The reason is that LINQ does not cache the results of the collection but it does recalculate the contents for every new enumeration again. Since I have used state (the Hashset does decide which entries are part of the output) I do arrive with an empty sequence since Add of the Hashset will return false for all values I have already passed in leaving nothing to return a second time. The solution is quite simple: Use the Distinct extension method or cache the results by calling .ToList() or ToArray() for the result of the LINQ query. Lession Learned: Do never forget to think about state in Where clauses!

• rake aborted! undefined local variable or method

  - by Subhransu

  In a fresh new Ubuntu machine, I have installed ruby with sudo apt-get install ruby1.8 and then installed rubygem1.8 with : sudo apt-get install rubygems and after that installed rails3.2.8 with : gem install rails The procedure was very simple. But here comes the problem. When I tried checking the version of rake with rake --trace -version I got the following error: rake aborted! undefined local variable or method `rsion' for #<Rake::Application:0xb72c731c> /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:316:in `standard_rake_options' /usr/lib/ruby/1.8/optparse.rb:1298:in `eval' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:316:in `standard_rake_options' /usr/lib/ruby/1.8/optparse.rb:1298:in `call' /usr/lib/ruby/1.8/optparse.rb:1298:in `parse_in_order' /usr/lib/ruby/1.8/optparse.rb:1254:in `catch' /usr/lib/ruby/1.8/optparse.rb:1254:in `parse_in_order' /usr/lib/ruby/1.8/optparse.rb:1248:in `order!' /usr/lib/ruby/1.8/optparse.rb:1339:in `permute!' /usr/lib/ruby/1.8/optparse.rb:1360:in `parse!' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:425:in `handle_options' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:74:in `init' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:72:in `init' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:64:in `run' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /var/lib/gems/1.8/gems/rake-0.9.2.2/lib/rake/application.rb:63:in `run' /var/lib/gems/1.8/gems/rake-0.9.2.2/bin/rake:33 /usr/local/bin/rake:19:in `load' /usr/local/bin/rake:19 Is it the problem due to I have installed straight from ubuntu apt-get package manager ?

• WPF or WinForms for Game Development and learning resources?

  - by Stephen Lee Parker

  I'm looking to create a game framework for my own personal use... I want to use WPF, but I'm unsure if that is a wise choice... The games I will be writing should not require high performance graphics, so I am hoping to build on native classes... I do not want to rely on external DLL's unless I generate them myself. The games will be for young children, say 4 to 8. Most will be learning puzzles or simple shooters. The most advanced will be a platform game (non-scrolling screen like the old Atari Miner 2049er game). I think I know how to write something like the old Atari Chopper Command (partially written and my 4 year old loves it, but I used WinForms and GDI), Pac-Man, Tetris, Astroids, Space Invaders, Slider Puzzle, but I do not really know how to write the platform game... In my mind, I'm getting caught in collision detection and how to make a character jump and how to make a character walk up a slope or steps... Can anyone point me to information on developing a platform game in C#? Would you suggest WinForms or WPF for game development? I'm not looking for great graphics and speed, just entertaining game play...

• Writing a "Hello World" Device Driver for kernel 2.6 using Eclipse

  - by Isaac

  Goal I am trying to write a simple device driver on Ubuntu. I want to do this using Eclipse (or a better IDE that is suitable for driver programming). Here is the code: #include <linux/module.h> static int __init hello_world( void ) { printk( "hello world!\n" ); return 0; } static void __exit goodbye_world( void ) { printk( "goodbye world!\n" ); } module_init( hello_world ); module_exit( goodbye_world ); My effort After some research, I decided to use Eclipse CTD for developing the driver (while I am still not sure if it supports multi-threading debugging tools). So I: Installed Ubuntu 11.04 desktop x86 on a VMWare virtual machine, Installed eclipse-cdt and linux-headers-2.6.38-8 using Synaptic Package Manager, Created a C Project named TestDriver1 and copy-pasted above code to it, Changed the default build command, make, to the following customized build command: make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 The problem I get an error when I try to build this project using eclipse. Here is the log for the build: **** Build of configuration Debug for project TestDriver1 **** make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 all make: Entering directory '/usr/src/linux-headers-2.6.38-8-generic' make: *** No rule to make target vmlinux', needed byall'. Stop. make: Leaving directory '/usr/src/linux-headers-2.6.38-8-generic' Interestingly, I get no error when I use shell instead of eclipse to build this project. To use shell, I just create a Makefile containing obj-m += TestDriver1.o and use the above make command to build. So, something must be wrong with the eclipse Makefile. Maybe it is looking for the vmlinux architecture (?) or something while current architecture is x86. Maybe it's because of VMWare? As I understood, eclipse creates the makefiles automatically and modifying it manually would cause errors in the future OR make managing makefile difficult. So, how can I compile this project on eclipse?

• Did you forget me?

  - by Ratman21

  I know it has been a long time since I last blogged. Still at it, looking for work in the “IT” field. Had another phone interview (only found out during the interview that it was for one year contract job, but I still would take it) for a Help Desk job. Didn’t get it, they thought I was not a application support person and more of a hardware support. Gee..I started out in “IT” as a programmer. Then a programmer/computer operator, then a Tandem/Lan operator and finally a Network operator. I had to deal with so many different operating systems, software and applications.   And they thought I was too hardware. Well I am working a temp day job with the U.S. Census. It gets me out of the house and out in the country. If find getting paid to check for living quarters not bad job, except for the many houses I find that are up for sale and looks like it was not the owners (former owners it seems) idea, with the kids toys still in the yards. Not good for some one with a over active imagine or for my truck. So far I have backed in to ditch (and had to be pulled out), in to power pole (no damage to pole and very little to truck) and a mail box (no damage to truck but mail box was leaning a little) in the last two weeks.   Oh an I have started reading/using “The Love Dare” book from the movie “Fireproof”. I restarted (yes I have had to go back to day one from day five) the dare this Sunday. Dare one dare/day one “Love Is Patient” and the first dare is (reading from the book is): “The first part of this dare is fairly simple. Although Love is communicated in a number of ways. Our words often reflect the condition of our heart. For the next day, resolve to demonstrate patience and to sys nothing negative to your spouse at all. If the temptation arises, choose not to say anything. It’s better to hold your tongue that to say something you’ll regret. “. This was almost too easy as I can hold back from saying anything bad to any one but, this can also be a problem in life (you hold back for so long and!!!!!!!!!!!!!! Boom). Check back for dare/day two “Love Is Kind”.

• How to use T4 templates in WP7, Silverlight, Desktop or even MonoDroid apps

  - by Daniel Cazzulino

  In other words, how to use T4 templates without ANY runtime dependencies? Yes, it is possible, and quite simple and elegant actually. In a desktop project, just open the Add New Item dialog, and search for "text template": From the two available templates, the one that gives you a zero-dependency runtime-usable template is the first one: Preprocessed Text Template. Once unfolded, you get the .tt file, but also a dependent .cs file automatically generated. Note the Custom Tool associated with the file: If you open up the .cs file, you will see that it doesn't contain the rendered "Hello World!!!" I added in the .tt, but rather a full class named after the template file itself: namespace ConsoleApplication1 { using System; #line 1 "C:\Temp\ConsoleApplication1\ConsoleApplication1\PreTextTemplate1.tt" [System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.VisualStudio.TextTemplating", "10.0.0.0")] public partial class PreTextTemplate1 : PreTextTemplate1Base { public virtual string TransformText() { this.GenerationEnvironment = null; this.Write("Hello World!!!"); return this.GenerationEnvironment.ToString(); } } #region Base class ... #endregion } ...

• Suggestions for implementing a dynamic 2D level

  - by Wouter

  I am working on a game that needs a level that is completely generated. Currently my approach is to draw textures for the levels pixel by pixel during the game (in XNA with SpriteBatch). This is too intensive unfortunately. The game has frame drops even when I only draw 1 level texture each draw cycle. Here is an example of the current prototype. It is a simple sidescroller with the avatar swimming through a cave. The shape of this cave will alter throughout the level (textures and physics collision shapes). You can clearly see the boundaries of the level tiles in the screenshot below. These are generated just before they move into camera view. For inspiration I looked at PixelJunk Shooter 2. These levels are obviously not generated, but some of the levels have movement. How do you guys think they implemented it? My guess is that the level and other objects in the game are actually flat 3d models, but I am not sure..

• Libgdx detect when player is outside of screen

  - by Rockyy

  Im trying to learn libGDX (coming from XNA/MonoDevelop), and I'm making a super simple test game to get to know it better. I was wondering how to detect if the player sprite is outside of the screen and make it so it is impossible to go outside of the screen edges. In XNA you could do something like this: // Prevent player from moving off the left edge of the screen if (player.Position.X < 0) player.Position = new Vector2(0, player.Position.Y); How is this achieved in libgdx? I think it's the Stage that handles the 2D viewport in libgdx? This is my code so far: private Texture texture; private SpriteBatch batch; private Sprite sprite; @Override public void create () { float w = Gdx.graphics.getWidth(); float h = Gdx.graphics.getHeight(); batch = new SpriteBatch(); texture = new Texture(Gdx.files.internal("player.png")); sprite = new Sprite(texture); sprite.setPosition(w/2 -sprite.getWidth()/2, h/2 - sprite.getHeight()/2); } @Override public void render () { Gdx.gl.glClearColor(1, 1, 1, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(-1f); else sprite.translateX(-10.0f); } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(1f); else sprite.translateX(10f); } batch.begin(); sprite.draw(batch); batch.end(); }

• release management system - architectural question

  - by Sonic Soul

  Every place i've worked created their own release process, and all of them worked pretty well, however it took pretty good effort (and often a dedicated team) to manage releases. I am currently at a new place, and about to design such a system, however this time the team is very lean and we won't have dedicated resources to releasing. It will be up to development manager until the system is proofed enough for other developers to use. we're using Subversion as code repository, Team City as the build server, Jira issue tracker, Oracle db. I was thinking about writing a basic workflow app, that will let developers create a new manifest which will specify the following items. release details (who, jira issues etc) workflow step (dev, test, uat, prod approved, prod released) source files that last item is where it can get hairy. especially with database scripts. Figured I'd ask if there is a good pattern, or off the shelf product that could help with the database part, or perhaps the whole process. I briefly tested Red Gate Oracle deployment tool, but it didn't work out as well as I had hoped (from 1 day of testing at least) Questions: I think I could get around releasing of our code with something like Octopus Deploy straight from Team City. I am not clear however, how I could create a simple database deployment part, that will track which version of which script (from subversion) has been deployed where. Is there already some utility I could utilize for navigating subversion to choose which scripts should be released, instead of writing one from scratch. I'd just need it to produce some manifest of paths + versions.

• Tips on combining the right Art Assets with a 2D Skeleton and making it flexible

  - by DevilWithin

  I am on my first attempt to build a skeletal animation system for 2D side-scrollers, so I don't really have experience of what may appear in later stages. So i ask advice from anyone that been there and done that! My approach: I built a Tree structure, the root node is like the center-of-mass of the skeleton, allowing to apply global transformations to the skeleton. Then, i make the hierarchy of the bones, so when moving a leg, the foot also moves. (I also make a Joint, which connects two bones, for utility). I load animations to it from a simple key frame lerp, so it does smooth movement. I map the animation hierarchy to the skeleton, or a part of it, to see if the structure is alike, otherwise the animation doesnt start. I think this is pretty much a standard implementation for such a thing, even if i want to convert it to a Rag Doll on the fly.. Now to my question: Imagine a game like prototype, there is a skeleton animation of the main character, which can animate all meshes in the game that are rigged the same way.. That way the character can transform into anything without any extra code. That is pretty much what i want to do for a side-scroller, in theory it sounds easy, but I want to know if that will work well. If the different people will be decently animated when using the same skeleton-animation pair. I can see this working well with a Stickman, but what about actual humans? Will the perspective look right, or i will need to dynamically change the sprites attached to bones? What do you recommend for such a system?

• Edge Detection on Screen

  - by user2056745

  I have a edge collision problem with a simple game that i am developing. Its about throwing a coin across the screen. I am using the code below to detect edge collisions so i can make the coin bounce from the edges of the screen. Everything works as i want except one case. When the coin hits left edge and goes to right edge the system doesnt detect the collision. The rest cases are working perfectly, like hitting the right edge first and then the left edge. Can someone suggest a solution for it? public void onMove(float dx, float dy) { coinX += dx; coinY += dy; if (coinX > rightBorder) { coinX = ((rightBorder - coinX) / 3) + rightBorder; } if (coinX < leftBorder) { coinX = -(coinX) / 3; } if (coinY > bottomBorder) { coinY = ((bottomBorder - coinY) / 3) + bottomBorder; } invalidate(); }
