  • Scripted Motion Paths (?) (XNA)

    - by Peteyslatts
    Ok, so the title isn't the greatest because this is a lot more general. Say I want to have the player be able to hit A and have their ship model roll to the right, and shift to the right of the screen, while the camera stays centered. Would I do that through programming (ie. set waypoints for the model and keep the camera focus still) or do it through animation ( so the ship model actually rolls and moves right, and just play those frames)(I actually don't know how to do this kind of 3D animation yet, haven't looked into it. Adding it to my To Do List) This is a really vague question I know, I'll try and answer any questions. Thanks, Peter

  • Time based movement Vs Frame rate based movement?

    - by sil3nt
    Hello there, I'm new to Game programmming and SDL, and I have been following Lazyfoo's SDL tutorials. My question is related to time based motion and frame rate based motion, basically which is better or appropriate depending on situations?. Could you give me an example where each of these methods are used?. Another question I have is that, in lazyfoo's two Motion tutorials (FPS based and time based) The time based method showed a much smoother animation while the Frame rate based one was a little hiccupy, meaning you could clearly see the gap between the previous location of the dot and its current position when you compare the two programs. As beginner which method should I stick to?(all I want is smooth animations).

  • Debian - Can't stop MySQL; permissions?

    - by anon
    I just tried to upgrade from debian squeeze to unstable by replacing 'squeeze' with 'unstable' in /etc/apt/sources.list. The upgrade went smoothly except for mysql, which failed because it couldn't stop mysql. /etc/init.d/mysql stop simply returns that it failed, but if I try to get the status with /etc/init.d/mysql status it gives me this error: me@debian:~$ sudo /etc/init.d/mysql status /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)' . mysql is running fine, and I checked the permissions for debian-sys-maint in phpmyadmin and it's allowed to do everything, but only connect from 'localhost.'

  • Looking for temporal upsampling / motion interpolation software

    - by timday
    I'm looking for something (prereably FOSS software) which can take an animation with N images as input, and which will output an animation with M frames, where M is in the range 2N to 5N or so. I believe the general technique is called "temporal upsampling" or possibly "inbetweening" (or "'tweening" for short). Note that it does need to make some effort to do motion tracking of things in the scene ("optical flow"); just fading ("dissolve") between keyframes isn't going to cut it. Googling "temporal upsampling" turns up any number of papers on the subject, but I've yet to discover any code/software (a gstreamer plugin would be perfect) I can just use to try the technique out. Any suggestions ? Additional information: "Motion interpolation" seems to be the more widely used name in the TV world for what I'm looking for. See this and the video here too. Interestingly, some cinephiles seem to hate what these technologies do to 24FPS film: e.g a comment "makes Gone With The Wind look like a soap opera shot on video".

  • Confusion on networking service start/stop in Ubuntu

    - by Daniel Ball
    I'm preparing to move and took down two of my servers, leaving only one with some essential services running. What I neglected to consider was that one was the DHCP server(which I realized when somebody contacted me saying they couldn't connect. Whups). So because I only have a few hosts on this small network, I opted to just statically configure them for now. One of these is a new Ubuntu 11.04 server, where I have very little experience. I edited /etc/network/interfaces and /etc/hosts to reflect my changes. I ran $sudo /etc/init.d/networking stop *deconfiguring network interfaces ... So yay. Then I try to start, it gives me the mumbo jumbo about using services (why didn't it do that for the stop?) So instead I run ... $sudo service networking start networking stop/waiting Now, to me that says the status of the service is stopped. But when I ping another computer, I get a successful reply. So is it not actually stopped? More importantly, am I doing something wrong? Edit daniel@FOOBAR:~$ sudo service networking status networking stop/waiting daniel@FOOBAR:~$ sudo service networking stop stop: Unknown instance: daniel@FOOBAR:~$ sudo service networking status networking stop/waiting daniel@FOOBAR:~$ sudo service networking start networking stop/waiting daniel@FOOBAR:~$ sudo service networking status networking stop/waiting So you can see why I ran /etc/init.d/networking stop instead. For some reason upstart (that is what "services" is, right?) isn't working with stop. cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 FOOBAR 198.3.9.2 FOOBAR #Added entry July 19 2011 # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface #auto eth0 #iface eth0 inet dhcp # hostname FOOBAR auto eth0 iface eth0 inet static address 198.3.9.2 netmask 255.255.255.0 network 198.3.9.0 broadcast 198.3.9.255 gateway 198.3.9.15 No I didn't save backups, it was just a minor change so I just commented out the old DHCP setting. Edit I set everything back to original settings and set up a DHCP server. "starting" networking does the same thing. I can only assume this is normal, I just don't know WHY. It can't be anything to do with the configuration files, since they've been restored.

  • Launching a PHP daemon from an LSB init script w/ start-stop-daemon

    - by EvanK
    I'm writing an lsb init script (admittedly something I've never done from scratch) that launches a php script that daemonizes itself. The php script starts off like so: #!/usr/bin/env php <?php /* do some stuff */ It's then started like so in the init script: # first line is args to start-stop-daemon, second line is args to php-script start-stop-daemon --start --exec /path/to/executable/php-script.php \ -- --daemon --pid-file=$PIDFILE --other-php-script-args The --daemon flag causes the php script to detach & run as a daemon itself, rather than relying on start-stop-daemon to detach it. This is how it's (trying to) stop it in the init script: start-stop-daemon --stop --oknodo --exec /path/to/executable/php-script.php \ --pidfile $PIDFILE The problem is, when I try to stop via the init script, it gives me this: $ sudo /etc/init.d/my-lsb-init-script stop * Stopping My Project No /path/to/executable/php-script.php found running; none killed. ...done. A quick peek at ps tells me that, even though the php script itself is executable, its running as php <script> rather than the script name itself, which is keeping start-stop-daemon from seeing it. The PID file is even being generated, but it seems to ignore it and try to find+kill by process name instead. $ ps ax | grep '/path/to/executable/php-script.php' 2505 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2507 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2508 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2509 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2518 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args $ cat /var/run/blah/blah.pid 2518 Am I completely misunderstanding something here? Or is there an easy way to work around this?

  • Comparing a saved movement with other movement with Kinect

    - by Ewerton
    I need to develop an application where a user (physiotherapist) will perform a movement in front of the Kinect, I'll write the data movement in the database and then the patient will try to imitate this motion. The system will calculate the similarity between the movement recorded and executed. My first idea is, during recording (each 5 second, by example), to store the position (x, y, z) of the points and then compare them in the execution time(by patient). I know that this approach is too simple, because I imagine that in people of different sizes the skeleton is recognized differently, so the comparison is not reliable. My question is about the best way to compare a saved motion with a movement executed (on the fly). PS: Sorry by my English.

  • Stop YouTube Videos from Automatically Playing in Chrome

    - by The Geek
    If you’ve actually used the internet before, you’ve probably come across a page with an auto-playing YouTube clip, and chances are good it was a rather annoying one. Here’s how to stop them from starting automatically in Chrome. We’ve already told you how to stop them from automatically playing if you’re a Firefox user (best answer: use Flashblock!), but now it’s time for Chrome users to get their turn. Use the Stop Autoplay for YouTube Extension The great thing about this extension is that it stops the video from playing, but it allows it to continue buffering, so when you do feel like playing the video, it’ll already be downloaded—really useful for people with slower internet connections. There’s no UI or anything fancy, just head to the extension page and click the Install button. If you want to get rid of it later, use the Tools –> Extensions menu (or you can type chrome://extensions/ into your address bar), and then click the Uninstall link for that add-on.   Download Stop Autoplay for YouTube [Google Chrome Extensions] Using FlashBlock for Chrome If you really wanted to, you could just disable Flash across the board using FlashBlock for Chrome. Once you’ve installed the extension, you won’t see any Flash elements anywhere, and you’ll have to move your mouse over them and click to enable them each time. When I installed the extension the first time, I noticed that YouTube was already in the allow list. I’m not sure if that’s the default setting or not, but you can use the icon in the address bar, or the Options from the Extensions panel to get to the settings page, and from there you can remove anything from the White List that you wouldn’t want. Another nice feature about Flash Block is that it can also block Silverlight, or you could simply uninstall or remove unnecessary Chrome plug-ins.

  • Stop animation playing automatically

    - by Starkers
    I've created an animation to animate a swinging mace. To do this I select the mace object in the scene pane, open the animation pane, and key it at a certain position at 0:00. I'm prompted to save this animation in my assets folder, which I do, as maceswing I then rotate the mace, move the slider through time and key it in a different position. I move the slider through time again, move the object to the original position and key it. There are now three things in my assets folder: maceswing appears to be my animation, but I have no idea what Mace Mace 1 and Mace 2 are. (I've been mucking around trying to get this working so it's possible Mace 1 and Mace 2 are just duplicates of Mace. I still want to know what they are though) When I play my game, the mace is constantly swinging, even though I didn't apply maceswing to it. I can't stop it. People say there's some kind of tick box to stop it constantly animating but I can't find it. My mace object only has an Animator component: Unticking this component doesn't stop the animation playing so I have no idea where the animation is coming from. Or what the Animator component actually does. I don't want this animation constantly playing. I only want it to play once when someone clicks a certain button: var Mace : Transform; if(Input.GetButtonDown('Fire1')){ Mace.animation.Play('maceswing'); }; Upon clicking the 'Fire1' button, I get this error: MissingComponentException: There is no 'Animation' attached to the "Mace" game object, but a script is trying to access it. You probably need to add a Animation to the game object "Mace". Or your script needs to check if the component is attached before using it. There is no 'Animation' attached to the "Mace" game object, and yet I can see it swinging away constantly. Infact I can't stop it! So what's causing the animation if the game object doesn't have an 'Animation' attached to it?

  • How to Change and Manually Start and Stop Automatic Maintenance in Windows 8

    - by Lori Kaufman
    Windows 8 has a new feature that allows you to automatically run scheduled daily maintenance on your computer. These maintenance tasks run in the background and include security updating and scanning, Windows software updates, disk defragmentation, system diagnostics, among other tasks. We’ve previously shown you how to automate maintenance in Windows 7, Vista, and XP. Windows 8 maintenance is automatic by default and the performance and energy efficiency has been improved over Windows 7. The program for Windows 8 automatic maintenance is called MSchedExe.exe and it is located in the C:\Windows\System32 directory. We will show you how you can change the automatic maintenance settings in Windows 8 and how you can start and stop the maintenance manually. NOTE: It seems that you cannot turn off the automatic maintenance in Windows 8. You can only change the settings and start and stop it manually. Can Dust Actually Damage My Computer?

  • Random walk- Brownian Motion

    - by Sam
    I've been assigned the project of creating a simple console app. that models brownian motion in a 2D plane. I wasn't given much information on how to do so (and I'm hoping that it's a pretty popular assignment so that I could get some insight) just that it relies on random number generation. I researched brownian motion for a little bit and saw some formulas that looked complicated, but by the description is just seems to have to move randomly within a certain number interval. Can anyone clarify? Am I to create a program that continually creates a random number in an interval and then modify the particles "x" and "y" coordinate or is there more to it? Thanks for any help.

  • Can I stop NUnit GUI test run from code under test?

    - by David White
    I'm using nunit.exe (v2.5.3, as it happens) for our testers to run UI tests of our web site, using WatiN. The regression test suite is up to around 100 tests. While the test suite is running, the test web site could go down for maintenance. It would be more efficient in those circumstances if the test suite would stop altogether, rather than attempting to run each remaining test, and failing. Is there any way to accomplish this?

  • 2D platformer gravity physics with slow-motion

    - by DD
    Hi all, I fine tuned my 2d platformer physics and when I added slow-motion I realized that it is messed up. The problem I have is that for some reason the physics still depends on framerate. So when I scale down time elapsed, every force is scaled down as well. So the jump force is scaled down, meaning in slow-motion, character jumps vertically smaller height and gravity force is scaled down as well so the character goes further in the air without falling. I'm sending update function in hopes that someone can help me out here (I separated vertical (jump, gravity) and walking (arbitrary walking direction on a platform - platforms can be of any angle) vectors): characterUpdate:(float)dt { //Compute walking velocity walkingAcceleration = direction of platform * walking acceleration constant * dt; initialWalkingVelocity = walkingVelocity; if( isWalking ) { if( !isJumping ) walkingVelocity = walkingVelocity + walkingAcceleration; else walkingVelocity = walkingVelocity + Vector( walking acceleration constant * dt, 0 ); } // Compute jump/fall velocity if( !isOnPlatform ) { initialVerticalVelocity = verticalVelocity; verticalVelocity = verticalVelocity + verticalAcceleration * dt; } // Add walking velocity position = position + ( walkingVelocity + initialWalkingVelocity ) * 0.5 * dt; //Add jump/fall velocity if not on a platform if( !isOnPlatform ) position = position + ( verticalVelocity + initialVerticalVelocity ) * 0.5 * dt; verticalAcceleration.y = Gravity * dt; }

  • Sprite Body can not stop

    - by Diken
    Hey i have issue regarding jump sprite body. In my code i am using moveLeft and moveRight Button and when i am press moveRight Button using following code if (moveRight.active==YES) { b2Vec2 force=b2Vec2(4,0); ballBody->SetLinearVelocity(force); } Its move perfectly and When i release this Button than sprite body stop using following code else { b2Vec2 force=b2Vec2(0,0); ballBody->SetLinearVelocity(force); } But when i put this else part then jump can not done. My jump code is following if (jumpSprite.active==YES) { NSLog(@"Jump Sprite"); b2Vec2 locationWorld; locationWorld=b2Vec2(0.0f,4.0f); double force=ballBody->GetMass(); ballBody->ApplyLinearImpulse(force*locationWorld, ballBody->GetWorldCenter()); } If i remove else part then jump will perform complete but sprite body can not stop after release button. So what to do?? Thanks in advance

  • Rotate to a set degree then stop Unity

  • Where can I find a list of 'Stop' words for Oracle fulltext search?

    - by Tyronomo
    I've a client testing the full text (example below) search on a new Oracle UCM site. The random text string they chose to test was 'test only'. Which failed; from my testing it seems 'only' is a reserved word, as it is never returned from a full text search (it is returned from metadata searches). I've spent the morning searching oracle.com and found this which seems pretty comprehensive, yet does not have 'only'. So my question is thus, is 'only' a reserved word. Where can I find a complete list of reserved words for Oracle full text search (10g)? Full text search string example; (<ftx>test only</ftx>) Update. I have done some more testing. Seems it ignores words that indicate places or times; only, some, until, when, while, where, there, here, near, that, who, about, this, them. Can anyone confirm this? I can't find this in on Oracle anywhere. Update 2. Post Answer I should have been looking for 'stop' words not 'reserved'. Updated the question title and tags to reflect.

  • Java mouse motion anywhere on screen

    I'm sure this is possible but all my searching is coming up blank. In Java is it possible to register for a mouse motion event outside of a Java app? So if the mouse pointer moves anywhere on the screen I get a call back. An approximation is possible with polling MouseInfo.getPointerInfo but there must be a better way. Thanks
