• Solaris 11 VNC Server is "blurry" or "smeared"

  - by user12620111

  I've been annoyed by quality of the image that is displayed by my VNC viewer when I visit a Solaris 11 VNC server. How should I describe the image? Blurry? Grainy? Smeared? Low resolution? Compressed? Badly encoded? This is what I have gotten used to seeing on Solaris 11: This is not a problem for me when I view Solaris 10 VNC servers. I've finally taken the time to investigate, and the solution is simple. On the VNC client, don't allow "Tight" encoding. My VNC Viewer will negotiate to Tight encoding if it is available. When negotiating with the Solaris 10 VNC server, Tight is not a supported option, so the Solaris 10 server and my client will agree on ZRLE.  Now that I have disabled Tight encoding on my VNC client, the Solaris 11 VNC Servers looks much better: How should I describe the display when my VNC client is forced to negotiate to ZRLE encoding with the Solaris 11 VNC Server? Crisp? Clear? Higher resolution? Using a lossless compression algorithm? When I'm on a low bandwidth connection, I may re-enable Tight compression on my laptop. In the mean time, the ZRLE compression is sufficient for a coast-to-coast desktop, through the corporate firewall, encoded with VPN, through my ISP and onto my laptop. YMMV.

• What version was installed? x64 or i686? What's the difference exactly?

  - by Seppo

  Okay, so heres my problem. I recently started migrating several services to individual VMs on my box, using VirtualBox 4.1. I created a new VirtualBox VM with guest type "Ubuntu (64 Bit)". I've already done this before and it worked like a charm. I then installed unbutu server (12.04) from the exact same dvd image. All the time I thought that it should have installed x64. I already put a few hours work into the new VM, migrating the webserver and mail system etc. Today I tried installing a x64 piece of software and it suddenly told me that it needed x64 and I had only i686. I checked uname -a and this is what it gave me: Linux hostname 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686 i386 GNU/Linux Any guesses what went wrong? All the time I was thinking I had a x64 system. Any way to move to a "real" x64? I have a second VM on this host which is running x64 just fine .. P.S.: grep --color=always -iw lm /proc/cpuinfo returns lm among the flags.

• Scaling sprite velocity / co-ordinatesin Android

  - by user22241

  I'm trying to find the answer to a question that I've had for a long time, but am having trouble finding it! I hope someone can help :-) I'm trying to find information on how to scale sprite velocity / movement / co-ordinates. What I mean by this is how do I get a sprite to move at the same speed relative to the screen size / DPI so that it takes the same amount of real-time to get from one side of the screen to the other? All of the posts pertaining to sprite scaling that I can find on the various forums relate to the size of the sprite, but this part of it I'm OK with so far, it's just that when I move a sprite, it kind of gets there at different speed depending on the dpi / resolution of the device. I hope I'm making sense. This is the code I have so far, instead of using explicit amounts, like 1, I'm using something like the following: platSpeedFloat= (1 * (dpi/160)); //Use '1' so on an MDPI screen, the sprite will move by 1 physical pixel Then basically what I'm doing is something like this: (all varialble previously declared) platSpeedSave+=platSpeedFloat; //Add the platSpeedFloat value to the current platSpeedSave value platSpeed=(int) platSpeedSave; //Cast to int so it can be checked in the following statement if (platSpeed==platSpeedSave) //Check the casted int value to float value stored previoiusly {floorY=floorY-platSpeed; //If they match then change the Y value platSpeedSave=0;} //Reset Would be grateful if someone could assists - hope I'm making sense. The above doesn't seems to work the sprite moves 'faster' on lower DPI screens. Thanks

• Looking for job advice [closed]

  - by EntryLevelJavaDeveloper

  I am a software developer for a government agency in DC, and I have recently completed one year of employment. I am generally dissatisfied with my experiences here. I do not want to gripe too much, but I do not spend a lot of time doing actual development on projects. I am asked to do everything under the sun: write requirements, review specs, test, attend random meetings, but actual coding makes up a small fraction of my time. The coding itself is fairly straightforward and simple so it feels like I am not growing from my experiences. I am not tasked with more challenging work, and I find the experiences are not rewarding. If I had a stronger resume/more work experience, I'd leave the position immediately but combined with the present economy, I am hesitant to leave. I have several questions: Does anybody have experiences like this? How did you make the most of it? I am currently doing some side projects, making simple webpages for people, but aside from that, and open source projects, what other things are out there? What are general benchmarks for a developer after one year of professional experience? What should I be expected to know/do? I am outsider (coming from a math/science background) so I do not know what exactly I should know/do. Is it possible to obtain a mentorship with a mid/senior developer to learn? If so, how can I go about making contacts in the DC area?

• Linux, GNU GCC, ld, version scripts and the ELF binary format -- How does it work? [closed]

  - by themoondothshine

  I'm trying to learn more about library versioning in Linux and how to put it all to work. Here's the context: I have two versions of a dynamic library which expose the same set of interfaces, say libsome1.so and libsome2.so. An application is linked against libsome1.so. This application uses libdl.so to dynamically load another module, say libmagic.so. Now libmagic.so is linked against libsome2.so. Obviously, without using linker scripts to hide symbols in libmagic.so, at run-time all calls to interfaces in libsome2.so are resolved to libsome1.so. This can be confirmed by checking the value returned by libVersion() against the value of the macro LIB_VERSION. So I try next to compile and link libmagic.so with a linker script which hides all symbols except 3 which are defined in libmagic.so and are exported by it. This works... Or at least libVersion() and LIB_VERSION values match (and it reports version 2 not 1). However, when some data structures are serialized to disk, I noticed some corruption. In the application's directory if I delete libsome1.so and create a soft link in its place to point to libsome2.so, everything works as expected and the same corruption does not happen. I can't help but think that this may be caused due to some conflict in the run-time linker's resolution of symbols. I've tried many things, like trying to link libsome2.so so that all symbols are alised to symbol@@VER_2 (which I am still confused about because the command nm -CD libsome2.so still lists symbols as symbol and not symbol@@VER_2), but nothing seems to work. What am I doing wrong?

• Why is heap size fixed on JVMs?

  - by themel

  Can anyone explain to me why JVMs (I didn't check too many, but I've never seen one that didn't do it that way) need to run on a fixed heap size? I know it's easier to implement on a simple contiguous heap, but the Sun JVM is now over a decade old, so I'd expect them to have had time to improve this. Needing to define the maximum memory size of your program at startup time seems such a 1960s thing to do, and then there are the bad interactions with OS virtual memory management (GC retrieving swapped out data, inability to determine how much memory the Java process is really using from the OS side, huge amounts of VM space wasted (I know, you don't care on your fancy 48bit machines...)). I also guess that the various sad attempts to build small operating systems inside the JVM (EE application servers, OSGi) are at least partially to blame on this circumstance, because running multiple Java processes on a system invariably leads to wasted resources because you have to give each of them the memory it might have to use at peak. Surprisingly, Google didn't yield the storms of outrage over this that I would expect, but they may just have been buried under the millions of people finding out about fixed heap size and just accepting it for a fact.

• Developing a TCK: Spec Lead Call for Spec Leads 20 December

  - by Heather VanCura

  The JCP Program will be hosting a Spec Lead call on 20 December on the topic of developing a Technology Compatibility Kit (TCK).  A Technology Compatibility Kit is a required output of a JSR at Final Release, along with the Specification and Reference Implementation (RI).   The TCK must test all aspects of a specification that impact how compatible an implementation of that specification would be, such as the public API and all mandatory elements of the specification. The Reference Implementation is required to pass the TCK. A vendor's implementation of a specification is only considered compatible if the implementation passes the TCK fully and completely.  The TCK is used to test implementations of the Final Specification to make sure that they are fully compatible. The call will be recorded and posted on the JCP.org multimedia page along with any related materials.   Invitation details for the online meeting:Topic: SL Call: Developing a TCK Date: Thursday, December 20, 2012 Time: 9:30 am, Pacific Standard Time (San Francisco, GMT-08:00) Meeting Number: 804 390 892 Meeting Password: 2222 ------------------------------------------------------- To join the audio conference -------------------------------------------------------     +1 (866) 682-4770 (US)     Conference code: 945-4597    Security code: 52775 ("JCPSL" on your phone handset)     For global access numbers see http://www.intercall.com/oracle/access_numbers.htm         Or +1 (408) 774-4073

• cannot log in to all account except guest after mounting new partition

  - by student

  I really really need help. to do my homework from school, since two days ago, I was installing oracle 11g on my ubuntu. through that process, there was lots of problems also, but searching a lot, in somehow I could go to the next phase installing it. (because it was the first time to install on ubuntu by myself..) but when I was making password for oracle and clicked next, it says there are not enough space for home/oracle folder, So to make another space, I mounted another space after checking Gparted and using Software device management, I mounted it. And when I rebooted it, since then, I cannot log in to my own administrator account and even to oracle account(that I made for oracle 11g on ubuntu ) when I type the passwords for it, it seems to work but it redisplay the first page to log in, without really logging in it.. So I loggined to here as guest account... and even I cannot try gnome console manipulation to restore or fix it.. because it is guest account... I`m struggling for three days and... help me, how do I need to do? and at the time oracle said it needs enough space for its home folder, how I should have done?

• Task-It Source Code

  Download Source Code I've received many questions about when the source code for the Task-It application will be released. Well, the time has finally come. I haven't been able to release this sooner due to the flurry of releases that have been coming out lately. Silverlight 4, WCF RIA Services, and even our Q1 Rad Controls. Each time I got the latest bits I ran into issues (either bugs or visual issues) in the Task-It that needed to be fixed. Having said that, the app is far from perfect. There are still some bugs lurking and things that need to be fixed up visually (especially the RadGridView filtering popup), but the main purpose of this app is to show the RadControls for Silverlight 4 in the context of a real-world application, and I don't want to keep delaying the release of the source code. Minimum requirements To run the app you will need the latest Silverlight bits. Silverlight 4 RTM, VS2010 and the ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How to reset a List c# and XNA [on hold]

  - by P3erfect

  I need to do a "retry" option when the player finishes the game.For doing this I thought to reset the lists of Monsters and other objects that moved at the first playing or which have been "killed".for example I have a list like that: //the enemy1 class is already done // in Game1 I declare it List<enemy1> enem1 = new List<enemy1>(); //Initialize method List<enemy1> enem1 = new List<enemy1>(); //LoadContent foreach (enemy1 enemy in enem1) { enemy.Load(Content); } enem1.Add(new enemy1(Content.Load<Texture2D>("enemy"), new Vector2(5900, 12600))); //Update foreach (enemy1 enemy in enem1) { enemy.Update(gameTime); } //after being shoted the enemies disappear and i remove them //if the monsters are shoted the bool "visible" goes from false to true for (int i = enem1.Count - 1; i >= 0; --i) { if (enem1[i].visible == true) enem1.RemoveAt(i); } //Draw foreach (enemy1 enemy in enem1) { if(enemy.visble==false) { enemy.Draw(spriteBatch, gameTime); } } //So my problem is to restart the game. I did this in Update method if(lost==false) { //update all the things... } if(lost==true)//this is if I die { //here I have to put the code that restore the list //I tried: foreach (enemy1 enemy in enem1) { enemy.visible=false; } player.life=3;//initializing the player,points,time player.position=initialPosition; points=0; time=0; }//the player works.. } } they should be drawn again but if I removed them they won't be drawn anymore.If I don't remove them ,instead, the enemies are in different places (because they follow me). Any suggestions to restore or reinitialize the list??

• Windows W8, L8 and now H8

  - by raccoon_tim

  Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

• Getting Requirements Right

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/10/28/getting-requirements-right.aspxI had a meeting with a stakeholder who stated “I bet you wish I wasn’t in these meetings”.  She said this because she kept changing what we thought the end product should look like.  My reply was that it would be much worse if she came in at the end of the project and told us we had just built the wrong solution. You have to take the time to get the requirements right.  Be honest with all involved parties as to the amount of time it is taking to refine the requirements.  The only thing worse than wrong requirements is a surprise in budget overages.  If you give open visibility to your progress then management has the ability to shift priorities if needed. In order to capture the best requirements use different approaches to help your stakeholders to articulate their needs.  Use mock ups and matrix spread sheets to allow them to visualize and confirm that everyone has the same understanding.  The goals isn’t to record every last detail, but to have the major landmarks identified so there are fewer surprises along the way. Help the team members to understand that you all have the same goal.  You want to create the best possible solution for the given business problem.  If you do this everyone involved will do there best to outline a picture of what is to be built and you will be able to design an appropriate solution to fill those needs more easily.

• New Workstation &ndash; Lenovo W530 Core i7 32GB 256GB SSD Win8Pro

  - by Brian Lanham

  So I pretty-much have my new machine up and running full-time. I am still going to have to hit my old workstation for some things but am more-or-less working on my new machine.  It’s really fast. And Bret was right, I’m not so far using all the RAM. 16 would have been enough but as @CodeMonkeyJava “go big or go home”. Windows 8 is…interesting.  So far I still seem to do most of my work in the “Desktop”.  However, I like the Store concept and I like the Metro UX.  Live tiles are also nice.  I really like how I can switch between Desktop and Metro easily.  Overall I think Microsoft has done a great job of combining the needed experience for touch and mouse. My overall Windows 8 rating is 5.9 because of the video card. Otherwise I’m hitting 7.8.  The system boots from cold in about 11 seconds and performs complete shutdown in 4.7 seconds.  It wakes from sleep in less than 1 second. VS 2012 starts and restarts almost instantly.  In fact, I find myself staring at the start page without realizing it.  Build time doesn’t seem to be significantly increased but it is faster. I seem to already be reinvigorated for work with this new machine. I’m looking forward to the performance.

• Collider2D and Rigidbody2D, how do they work?

  - by user42646

  I have been learning JavaScript and Unity for a week now. I learned how to make Cube as a Ground and another Cube as a player and I used this code to make the Player Cube move forward and backward and jumping var walkspeed: float = 5.0; var jumpheight: float = 250.0; var grounded = false; function Update() { rigidbody.freezeRotation = true; if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetButton("Jump")) { Jump(); } } function OnCollisionEnter(hit: Collision) { grounded = true; } function Jump() { if (grounded == true) { rigidbody.AddForce(Vector3.up * jumpheight); grounded = false; } } I also learned how to make a character hit box. how to make a sprite and animation. pretty much the basic stuff. Couple of days ago I created simple ground in Photoshop and a simple character and imported them to Unity3D. Whenever I use my code above the character keeps falling from the scene. Like the character has nothing to stand on. After thinking about it it make sense because I really didn't make anything to make the player character understand that he should stand on something so I started reading about this issue and I realized that there is something called Collider2D and Rigidbody2D. Now I'm really stuck here I just don't know what to do. I applied the rigibody2d to my character picture and the Collider2D to the ground picture but whenever I play the project the gravity makes my character falls down. This is my question: How can I make the rigibody2d object realize that it shouldn't fall if there is a Collider2D object under it? So when I jump it's going to jump and the gravity going to bring it back to the ground.

• what will EcmaScript 6 bring to the table for us

  - by user697296

  Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

• Why doesn't wireless work on Wubi 12.04 with a Broadcom BCM4312 card?

  - by Kristin

  I have recently set up ubuntu 12.04 on my laptop using the Wubi installer. I am having a very difficult time setting up a wireless internet connection. I am currently set up with an ethernet connection which I have used to download all new updates and to activate the Broadcom STA wireless driver. I have tried several things in the terminal based on other people's posts: ~$ rfkill list 0: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: yes ~$ rfkill unblock all It doesn't change anything. I also tried rebooting and connecting to the internet on my Windows Vista OS, and it worked, so I know that the connection should not be hard blocked. I have also tried installing b43 firmware (lp/phy version) that is supposed to work with my chip (BCM4312). It seems to have no effect. Then I tried: ~$ iwconfig lo no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:0 Noise level:0 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 eth0 no wireless extensions. This is my first time trying to work with ubuntu, so I would appreciate any help. Thanks. Also sorry this is poorly formatted. I'm having troubles with that too.

• One of my VMs went boom using Virtual Box and how it got fixed

  - by Enrique Lima

  I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

• What makes a theme "Premium"

  - by Sinthia V

  I have a lot of time invested in creating Wordpress templates. I want to release combinations of these templates along with different styles and Fancy Front pages as "Premium Wordpress Themes". What I need to know is what does "Premium" mean? What do people expect of a GPL theme vs. a Premium theme? Are there features that are considered required to be premium? Are there features that are in demand but considered "exceptional" i.e. not part of every premium theme? How can I tell the difference? I have heard tounge-in-cheek answers that say that any theme that makes money is premium, but I mean to ask about what gives an outstanding theme it's quality. Why is it worth more? I am technically able to do many things, but as a lone developer with a family to feed, I can't afford to spend time on features that no one cares about. I have to try to isolate the things that people want. This is serious food and rent to me. How can I get this kind of info so I can make my project successful?

• Has anyone used game salad before and how does it compare with cocos2d in terms of 2d game development

  - by jih

  First a short intro. I am new to the game development space and want to make some 2d games for iOS. I first come across cocos2d and kobold but then wanted something more graphical for rapid prototyping. I then found Game Maker which doesn't support iOS but is fairly easy to learn and then found Game Salad which supports iOS as well as other platforms. I know this question has been ask before but I want to know in terms of the types of games I want to develop what an learning investment path would be best. The types of games genre I am interest are: Side scrollers Simple games like diamond dash or ninja fruits, shanghai, etc Old fashioned zelda or dragonquest type (nintendo fan here:-) 2d adventure RPG games (real time or turn based) Mystery turn based games like carmen sandiego, wizardry, myst etc. So now the question becomes Which game development environment should I invest my time in learning. Game Salad or cocos2d? It would seem game salad would be great for quickies being graphical but in terms of 2d platform games etc would there be speed/performance/feature penalties? Are there certain 2d games genre of the 4 above that Game salad is better at while certain type cocos2d would be better at? Anyone with experience of both can share some pointers? Thanks. inexperienced jih

• Domain Specific Software Engineering (DSSE)

  Domain Specific Software Engineering (DSSE) believes that creating every application from nothing is not advantageous when existing systems can be leveraged to create the same application in less time and with less cost.  This belief is founded in the idea that forcing applications to recreate exiting functionality is unnecessary. Why would we build a better wheel when we already have four really good and proven wheels? DSSE suggest that we take an existing wheel and just modify it to fit an existing need of a system. This allows developers to leverage existing codebases so that more time and expense are focused on creating more usable functionality compared to just creating more functionality. As an example, how many functions do we need to create to send an email when one can be created and used by all other applications within the existing domain? Key Factors of DSSE Domain Technology Business A Domain in DSSE is used to control the problem space for a project. This control allows for applications to be developed within specific constrains that focus development is to a specific direction.Technology in DSSE offers a variety of technological solutions to be applied within a domain. Technology Examples: Tools Patterns Architectures & Styles Legacy Systems Business is the motivator for any originations to use DSSE in there software development process. Business reason to use DSSE: Minimize Costs Maximize market and Profits When these factors are used in combination additional factors and benefits can be found. Result of combining Key Factors of DSSE Domain + Business  = Corporate Core Competencies Domain expertise improved by market and business expertise Domain + Technology = Application Family Architectures All possible technological solutions to problems in a domain without any business constraints.  Business + Technology =  Domain independent infrastructure Tools and techniques for building systems  independent of all domains  Domain + Business + Technology = Domain-specific software engineering Applies technology to domain related goals in the context of business and market expertise

• CCMoveBy values on update()

  - by Jose M Pan

  Hope you can help me. This is my problem: I have a scheduled update, here I track the movements of my objects (sprites), I move them with CCMoveBy, and I need to constantly update the zOrder. For setting the zOrder I've made a setZOrder(), which it takes the actual position of the sprite. And here is the problem, I get all the X and Y values AFTER the object is in the target. I know I get the values after the object is in the new position because I've made a CCLog. I can read all the values from the sprite, only when it's in the new position, so everything is well sorted only when the objects are not moving. How can I get the CCMoveBy values on every tick update? (or how can I get the CCMoveBy values in "real-time"?) Thanks a lot in advance, Here is an idea of my code. this->schedule(schedule_selector(Game::update)); void Game::update(float dt) { setZOrder(); moveObjects(); } void Game::setZOrder() { //This function takes the X and Y position and the row and column where the sprite is. Is working good. But I'm getting the "move" action values, after the object is in place. } void Game::moveObjects() { for (i=0; i < numChildren; i++) { CCActionInterval* move = CCMoveBy::create(targetPoint, time); object[i]->runAction(move); } }
