  • I can't get grub menu to show up during boot

    - by wim
    After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • Tomcat's connection pool opens only 20 connections to mysql

    - by stck
    I have a java application with following line in context.xml <Resource driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" initialSize="10" maxWait="7000" name="jdbc/app" password="pass" type="javax.sql.DataSource" url="jdbc:mysql://dbhost:3306/dbname?autoReconnect=true" username="user" validationQuery="SELECT 1" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="true" /> In mysql 'show variables' tells me that max_connections is 151. Still, use information_schema; select count(*) from processlist where User = 'user'; never shows me more than 20 connections.

  • Upgrading a hard disk – To repave or to migrate, that is the question

    - by guybarrette
    I recently changed my laptop hard disk from the stock 250GB 5400 drive to a 320GB 7200 drive.  And no, I didn’t bought a SSD drive because the cost is way too much right now.  At $70, my upgrade was a lot cheaper than a SSD drive.  Maybe next year. When changing a system main hard drive, one must ask himself: To repave or to migrate, that is the question.  I choose to migrate so I went to the Acronis Website to take a look at their product line.  They have a few products that could do the job.  One being Acronis Migrate Easy 7.0 and the other being Acronis True Image Home 2010.  Since True Image was just $10 more then Migrate Easy, I bought True Image. I inserted my new hard drive in a 2.5” USB enclosure, and started the migration process.  Once the data copied, I switched the drives.  The process went very smoothly and without hiccups.  Highly recommended. BTW, Acronis offers free trials so I guess that nothing can stop you from “testing” a migration  ;-) var addthis_pub="guybarrette";

  • SEO, IIS 7 and web.config in subfolder issue

    - by tesicg
    We have ASP.NET application that has sub-folder with .aspx pages and separate web.config file in it. The .aspx pages in that sub-folder behave as separate site. In the web.config file at application level, I set the rule that removing trailing slashes: <rewrite> <rules> <rule name="RemoveTrailingSlashRule1" stopProcessing="true"> <match url="(.*)/$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> </conditions> <action type="Redirect" redirectType="Permanent" url="{R:1}" /> </rule> </rules> </rewrite> I expect this rule will propagate downward to sub-folder as well. To access the site in sub-folder we should type: http://concert.local/elki/ and get it without trailing slash as: http://concert.local/elki But, the trailing slash remains. The web.config file in sub-folder looks as following: <configuration> <system.webServer> <defaultDocument> <files> <add value="Sections.aspx" /> </files> </defaultDocument> </system.webServer> </configuration>

  • Single complex or multiple simple autoload functions [on hold]

    - by Tyson of the Northwest
    Using the spl_autoload_register(), should I use a single autoload function that contains all the logic to determine where the include files are or should I break each include grouping into it's own function with it's own logic to include the files for the called function? As the places where include files may reside expands so too will the logic of a single function. If I break it into multiple functions I can add functions as new groupings are added, but the functions will be copy/pastes of each other with minor alterations. Currently I have a tool with a single registered autoload function that picks apart the class name and tries to predict where it is and then includes it. Due to naming conventions for the project this has been pretty simple. if has namespace if in template namespace look in Root\Templates else look in Root\Modules\Namespace else look in Root\System if file exists include But we are starting to include Interfaces and Traits into our codebase and it hurts me to include the type of a thing in it's name. So we are looking at instead of a single autoload function that digs through the class name and looks for the file and has increasingly complex logic to it, we are looking at having multiple autoload functions registered. But each one follows the same pattern and any time I see that I get paranoid about code copying. function systemAutoloadFunc logic to create probable filename if filename exists in system include it and return true else return false function moduleAutoloadFunc logic to create probable filename if filename exists in modules include it and return true else return false Every autoload function will follow that pattern and the last of each function if filename exists, include return true else return false is going to be identical code. This makes me paranoid about having to update it later across the board if the file_exists include pattern we are using ever changes. Or is it just that, paranoia and the multiple functions with some identical code is the best option?

  • Removing ocurrances of characters in a string

    - by DmainEvent
    I am reading this book, programming Interviews exposed by John Wiley and sons and in chapter 6 they are discussing removing all instances of characters in a src string using a removal string... so removeChars(string str, string remove) In there writeup they sey the steps to accomplish this are to have a boolean lookup array with all values initially set to false, then loop through each character in remove setting the corresponding value in the lookup array to true (note: this could also be a hash if the possible character set where huge like Unicode-16 or something like that or if str and remove are both relatively small... < 100 characters I suppose). You then iterate through the str with a source and destination index, copying each character only if its corresponding value in the lookup array is false... Which makes sense... I don't understand the code that they use however... They have for(src = 0; src < len; ++src){ flags[r[src]] == true; } which is turning the flag value at the remove string indexed at src to true... so if you start out with PLEASE HELP as your str and LEA as your remove you will be setting in your flag table at 0,1,2... t|t|t but after that you will get an out of bounds exception because r doesn't have have anything greater than 2 in it... even using there example you get an out of bounds exception... Am is there code example unworkable?

  • How to choose between using a Domain Event, or letting the application layer orchestrate everything

    - by Mr Happy
    I'm setting my first steps into domain driven design, bought the blue book and all, and I find myself seeing three ways to implement a certain solution. For the record: I'm not using CQRS or Event Sourcing. Let's say a user request comes into the application service layer. The business logic for that request is (for whatever reason) separated into a method on an entity, and a method on a domain service. How should I go about calling those methods? The options I have gathered so far are: Let the application service call both methods Use method injection/double dispatch to inject the domain service into the entity, letting the entity do it's thing and then let it call the method of the domain service (or the other way around, letting the domain service call the method on the entity) Raise a domain event in the entity method, a handler of which calls the domain service. (The kind of domain events I'm talking about are: http://www.udidahan.com/2009/06/14/domain-events-salvation/) I think these are all viable, but I'm unable to choose between them. I've been thinking about this a long time and I've come to a point where I no longer see the semantic differences between the three. Do you know of some guidelines when to use what?

  • How to enable systemd instantiated service with puppet?

    - by Richard Pena
    I've got the following puppet service: service { "[email protected]": provider => systemd, ensure => running, enable => true, } When I try to apply this configuration on my client, it throws the following error: err: /Stage[main]//Node[puppetclient]/Service[[email protected]]/enable: change from false to true failed: Could not enable [email protected]: The service is running fine and I can make sure it's started on system boot by adding a symlink to getty.target.wants: ln -s /lib/systemd/system/[email protected] /etc/systemd/system/getty.target.wants/[email protected] Of source, I could go ahead and remove "enable = true" from the service definition and include a the symlink manually in the puppet configuration, but shouldn't puppet take care of this? Am I doing something terribly wrong?

  • Making efficeint voxel engines using "chunks"

    - by Wardy
    Concept I'm currently looking in to how voxel engines work with a view to possibly making one myself. I see a lot of stuff like this ... https://sites.google.com/site/letsmakeavoxelengine/home/chunks ... which talks about how to go about reducing the draw calls. What I can't seem to understand is how it actually saves draw call counts on the basis of the logic being something like this ... Without chunks foreach voxel in myvoxels DrawIfVisible() With Chunks foreach chunk in mychunks DrawIfVisible() which then does ... foreach voxel in myvoxels DrawIfVisible() So surely you saved nothing ?!?! You still make a draw call for each visible voxel do you not? A visible voxel needs a draw call in either scenario. The only real saving I can see is that the logic that evaluates a chunk will be able to determine if a large number of voxels are visible or not effectively saving a bit of "is this chunk visible" cpu time. But it's the draw calls that interest me ... The fewer of those, the faster the application. EDIT: In case it makes any difference I will probably be using XNA (DX not OpenGL) for my engine so don't consider my choice of example in the link above my choice of technology. But this question is such that I doubt it would matter.

  • asterisk outbound caller id

    - by MCS
    I'm trying to set the caller id number for an outbound call. My asterisk .call file looks like this: Channel: SIP/flowroute/1234567890 Context: test Extension: 1234567890 Priority: 1 Here's my extensions.conf: [test] exten => _1NXXXXXXXXX,1,Set(CALLERID(num)=8005552222) exten => _1NXXXXXXXXX,n,Dial(SIP/${EXTEN}@flowroute) exten => _1NXXXXXXXXX,n,Playback(hello-world) When I receive the call, the caller id number is 1-206-445-6979, even though the CDR log has both src and clid set to 8005552222. I'm using flowroute as my carrier. Is there something wrong on their side?

  • How to stop reducing life? [closed]

    CODE Input input = gc.getInput(); int xpos = Mouse.getX(); int ypos = Mouse.getY(); emu = "Enemy Life : " + enemyLife; Life = "Your Life Is" + life; Mousepos = "X:" + xpos + "Y:" + ypos; //test test1 = "Test INT" + test1int; if(!repeatStop) { //if this button is press, the damage will add up.

It did not stop it // from reducing further. if(test1int>10) { floodControl1=true; } } QUESTION: Ok now, this is what is does. When I press the key, 1, it adds up the damage to the enemy. When I press fight, It will then start to reduce the enemy's health. Now my problem is, it kept on reducing and deducting it until negative! How do I deduct it to my desired damage (My desired damage is the one when press key 1)?

  • How do I automatically start Clamz with AMZ files for Amazon MP3 downloads?

    - by Takkat
    Chromium can open downloaded files with the default application (e.g. PDF in Evince). In my setup a downloaded .AMZ (for Amazon MP3) always opened with Gedit. However I would like to have all downloaded .amz files to autromatically open with Clamz, a command line tool for downloading that works like a charm. As in Nautilus my .amz files were associated to open with Gedit too I thought it was a good idea to add a clamz.desktop file in ~/.local/share/applications (according to this answer) [Desktop Entry] Encoding=UTF-8 Name=Clamz Comment=Open AMZ files for Amazon MP3 download Exec=/usr/bin/clamz %u Terminal=True Type=Application Icon= Categories=Application; StartupNotify=true MimeType=audio/x-amzxml; NoDisplay=true This lets me choose Clamz as default application in Nautilus. But when opening an .amz file in Nautilus it still does not open with Clamz as expected but is treated as an executable text file instead (note that the executable bit is not set!). Is there any other way to make Chromium or Nautilus always open an .amz file with Clamz? Did I miss to change setting in another place?

  • REST API wrapper - class design for 'lite' object responses

    - by sasfrog
    I am writing a class library to serve as a managed .NET wrapper over a REST API. I'm very new to OOP, and this task is an ideal opportunity for me to learn some OOP concepts in a real-life situation that makes sense to me. Some of the key resources/objects that the API returns are returned with different levels of detail depending on whether the request is for a single instance, a list, or part of a "search all resources" response. This is obviously a good design for the REST API itself, so that full objects aren't returned (thus increasing the size of the response and therefore the time taken to respond) unless they're needed. So, to be clear: .../car/1234.json returns the full Car object for 1234, all its properties like colour, make, model, year, engine_size, etc. Let's call this full. .../cars.json returns a list of Car objects, but only with a subset of the properties returned by .../car/1234.json. Let's call this lite. ...search.json returns, among other things, a list of car objects, but with minimal properties (only ID, make and model). Let's call this lite-lite. I want to know what the pros and cons of each of the following possible designs are, and whether there is a better design that I haven't covered: Create a Car class that models the lite-lite properties, and then have each of the more detailed responses inherit and extend this class. Create separate CarFull, CarLite and CarLiteLite classes corresponding to each of the responses. Create a single Car class that contains (nullable?) properties for the full response, and create constructors for each of the responses which populate it to the extent possible (and maybe include a property that returns the response type from which the instance was created). I expect among other things there will be use cases for consumers of the wrapper where they will want to iterate through lists of Cars, regardless of which response type they were created from, such that the three response types can contribute to the same list. Happy to be pointed to good resources on this sort of thing, and/or even told the name of the concept I'm describing so I can better target my research.

  • Checking validation of entries in a Sudoku game written in Java

    - by Mico0
    I'm building a simple Sudoku game in Java which is based on a matrix (an array[9][9]) and I need to validate my board state according to these rules: all rows have 1-9 digits all columns have 1-9 digits. each 3x3 grid has 1-9 digits. This function should be efficient as possible for example if first case is not valid I believe there's no need to check other cases and so on (correct me if I'm wrong). When I tried doing this I had a conflict. Should I do one large for loop and inside check columns and row (in two other loops) or should I do each test separately and verify every case by it's own? (Please don't suggest too advanced solutions with other class/object helpers.) This is what I thought about: Main validating function (which I want pretty clean): public boolean testBoard() { boolean isBoardValid = false; if (validRows()) { if (validColumns()) { if (validCube()) { isBoardValid = true; } } } return isBoardValid; } Different methods to do the specific test such as: private boolean validRows() { int rowsDigitsCount = 0; for (int num = 1; num <= 9; num++) { boolean foundDigit = false; for (int row = 0; (row < board.length) && (!foundDigit); row++) { for (int col = 0; col < board[row].length; col++) { if (board[row][col] == num) { rowsDigitsCount++; foundDigit = true; break; } } } } return rowsDigitsCount == 9 ? true : false; } I don't know if I should keep doing tests separately because it looks like I'm duplicating my code.

  • Could a singleton type replace static methods and classes?

    - by MKO
    In C# Static methods has long served a purpose allowing us to call them without instantiating classes. Only in later year have we became more aware of the problems of using static methods and classes. They can’t use interfaces They can’t use inheritance They are hard to test because you can’t make mocks and stubs Is there a better way ? Obviously we need to be able to access library methods without instantiated classes all the time otherwise our code would become pretty cluttered One possibly solution is to use a new keyword for an old concept: the singleton. Singleton’s are global instances of a class, since they are instances we can use them as we would normal classes. In order to make their use nice and practical we'd need some syntactic sugar however Say that the Math class would be of type singleton instead of an actual class. The actual class containing all the default methods for the Math singleton is DefaultMath, which implements the interface IMath. The singleton would be declared as singleton Math : IMath { public Math { this = new DefaultMath(); } } If we wanted to substitute our own class for all math operations we could make a new class MyMath that inherits DefaultMath, or we could just inherit from the interface IMath and create a whole new Class. To make our class the active Math class, you'd do a simple assignment Math = new MyMath(); and voilá! the next time we call Math.Floor it will call your method. Note that for a normal singleton we'd have to write something like Math.Instance.Floor but the compiler eliminates the need for the Instance property Another idea would be to be able to define a singletons as Lazy so they get instantiated only when they're first called, like lazy singleton Math : IMath What do you think, would it have been a better solution that static methods and classes? Is there any problems with this approach?

  • Allowing client to select data to return via REST interface

    - by CMP
    I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?

  • Should static parameters in an API be part of each method?

    - by jschoen
    I am currently creating a library that is a wrapper for an online API. The obvious end goal is to make it as easy for others to use as possible. As such I am trying to determine the best approach when it comes to common parameters for the API. In my current situation there are 3 (consumer key, consumer secret, and and authorization token). They are essentially needed in every API call. My question is should I make these 3 parameters required for each method or is there a better way. I see my current options as being: Place the parameters in each method call public ApiObject callMethod(String consumerKey, String consumerSecret, String token, ...) This one seems reasonable, but seems awfully repetitive to me. Create a singleton class that the user must initialize before calling any api methods. This seems wrong, and would essentially limit them to accessing one account at a time via the API (which may be reasonable, I dunno). Make them place them in a properties file in their project. That way I can load the properties that way and store them. This seems similar to the singleton to me, but they would not have to explicitly call something to initialize these values. Is there another option I am not seeing, or a more common practice in this situation that I should be following?

  • 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??

  • Basic questions while making a toy calculator

    - by Jwan622
    I am making a calculator to better understand how to program and I had a question about the following lines of code: I wanted to make my equals sign with this C# code: private void btnEquals_Click(object sender, EventArgs e) { if (plusButtonClicked == true) { total2 = total1 + Convert.ToDouble(txtDisplay.Text); //double.Parse(txtDisplay.Text); } else if (minusButtonClicked == { total2 = total1 - double.Parse(txtDisplay.Text) } } txtDisplay.Text = total2.ToString(); total1 = 0; However, my friend said this way of writing code was superior, with changes in the minus sign. private void btnEquals_Click(object sender, EventArgs e) { if (plusButtonClicked == true) { total2 = total1 + Convert.ToDouble(txtDisplay.Text); //double.Parse(txtDisplay.Text); } else if (minusButtonClicked == true) { double d1; if(double.TryParse(txtDisplay.Text, out d1)) { total2 = total1 - d1; } } txtDisplay.Text = total2.ToString(); total1 = 0; My questions: 1) What does the "out d1" section of this minus sign code mean? 2) My assumption here is that the "TryParse" code results in fewer systems crashes? If I just use "Double.Parse" and I don't put anything in the textbox, the program will crash sometimes right?

  • Resolving Domainnames differently for different services

    - by mlaug
    Some time ago we had an issue with our network infrastructure and php with curl. Our Network infrastructure is fairly simple. LoadBalancer/Firewall = 5 servers The Domainname of our website is set to the ip of the Loadbalancer, of course. But calling curl from one of the servers did result in a timeout. It appears that a server could not call for its own domain it is serving. So we had to set the domains via /etc/hosts to the sever itself. But now We have implemented a Varnish in front of the Loadbalancer, which we want to automatically purge, once a change on a page happens. So now we need to call the domain www.example.com/url_to_purge. Sadly this call what be resolved to the server itself instead of the varnish, because of the /etc/hosts entries. So now I am wondering, if you could resolve domain names differently for different services :)

  • Basic SDL2 Code which "Stop working" when calling SDL_Quit() [migrated]

    - by Rivten
    So I got into SDL2 with C++ quite recently and I did this very simple code : int main(int argc, char** argv) { SDL_Event *event; bool done = false; if(SDL_Init(SDL_INIT_VIDEO) != 0) { std::cerr << "Problèmes pour initialiser la SDL : " << SDL_GetError() << std::endl; return 1; } SDL_Window *window = 0; window = SDL_CreateWindow("Mopion", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN); if(window == 0) { done = true; } while(!done) { while(SDL_PollEvent(event)) { switch(event->type) { case SDL_QUIT: done = true; break; case SDL_KEYUP: if(event->key.keysym.sym == SDLK_q) { done = true; } break; default: break; } } } SDL_DestroyWindow(window); SDL_Quit(); return 0; } While that code executes at first quite well, when I hit the "Q" key, the window closes but I got a Windows Error Window saying that "My program stopped working." which is not very convenient. Using the debugger, I found that everything is fine until SDL_Quit() is called. Anyone has any idea why this is going on ? Thanks a lot !

  • Can i add friction in air?

    - by Diken
    I have issue regarding speed in air. When i jump and move simultaneously that time speed of player increase.For jump i am using impuls and for movement i am using force.I want to slow speed when player is in air. Thanks in advance Following is my update method ih HUDLayer -(void)update:(ccTime)dt :(b2Body *)ballBody :(CCSprite *)player1 :(b2World *)world { if (moveRight.active==YES) { ballBody->SetActive(true); b2Vec2 locationworld=b2Vec2(maxSpeed,0); double mass=ballBody->GetMass(); ballBody->ApplyForce(mass*locationworld, ballBody->GetWorldCenter()); // ballBody->SetLinearDamping(1.2f); } else if(moveLeft.active==YES) { ballBody->SetActive(true); b2Vec2 locationworld=b2Vec2(-10,0); double mass=ballBody->GetMass(); ballBody->ApplyForce(mass*locationworld, ballBody->GetWorldCenter()); // ballBody->SetLinearDamping(1.2f); } } Following is jump -(void)jump:(b2Body*)ballBody:(ccTime)dt:(BOOL)touch { if (touch) { if (jumpSprte.active==YES) { ballBody->SetActive(true); b2Vec2 locationWorld; //locationWorld=b2Vec2(0.0f,98.0f); locationWorld=b2Vec2(0,32); // double mass=ballBody->GetMass(); ballBody->ApplyLinearImpulse(locationWorld, ballBody->GetWorldCenter()); // ballBody->ApplyForce(mass*locationWorld, ballBody->GetWorldCenter()); ballBody->SetLinearDamping(1.2f); } } } So where i apply logic??
