• Target tracking with a small delay (actionscript 3.0)

  - by John Dodson

  I'm having trouble thinking of a good method to track my character with an enemy attack. Of course, I don't want the attack to track my character's current position; I want it to track where the character was about 1 second before (so you can move around and make the attack miss and loop around you sort of a thing). The general structure of my game uses a timer to update all of my events. I have a timer going off every 25 milliseconds that updates everything, including my player's position and the enemies position. Right now I just have the enemy attack directly targeting my character....which works fine except that it's impossible to escape =p. Let me know if I didn't supply enough details. My approach was going to basically be get my character's position from about 1 second ago, then have the enemy target that position, the only problem is I can't think of a good way to get my character's position from previous times. Thanks for the help!

• GPU On-the-fly encoding of video through Logitech HD Webcam C510

  - by Ashfame

  Originally asked here but I edited that to move this question as a different one on suggestion by a fellow member. I read that I should have a Core2Duo 2.2Ghz for 720p but I have a 2.0Ghz one, would it be possible for me to first record it and then encode it after recording if my processor really start giving issue when doing on-the-fly encoding? I also have a ATI HD 4850 512MB card, if it can help in encoding on-the-fly or is there a chance that my graphics card alone can handle it and those specs were just for a system without a graphics card? I believe so. Also, I got no worries in dealing with console, if I have to do some of the things above in terminal. Other possible significant details: I have a dual screen setup 29" (1360X768) & 22" (1680X1050) which might be using some good power from GPU and I have 2GB DDR2 800Mhz RAM.

• Defining the track in a 2D racing game

  - by Ivan

  I am designing a top-down racing game using canvas (html5) which takes a lot of inspiration from Micro Machines. In MM, cars can move off the track, but they are reset/destroyed if they go too far. My maths knowledge isn't great, so I'm finding it hard to separate 3D/complex concepts from those which are directly relevant to my situation. For example, I have seen "splines" mentioned, is this something I should read up on or is that overkill for a 2D game? Could I use a single path which defines the centre of the track and check a car's distance from this line? A second path might be required as a "racing line" for AI. Any advice on methods/techniques/terms to read up on would be greatly appreciated.

• StreamInsight Licensing

  I cannot help but think that this is currently wrong.  There are two editions of StreamInsight (SI), Premium and Standard.  A link to their differences is here Points to note Developer Edition and Evaluation Edition represent Enterprise Edition in SQL Server but not SI where they represent Datacentre Edition.  Won’t this be confusing when people evaluating SI find that it is not the same animal when they move to Enterprise Edition? If SI Premium is the only thing you want out of the SQL Server box then it is going to be a high cost. The latency rates as well quoted on the site above make Premium Edition essential if you are going to be using this to do Real-Time analytics.

• Wanting to learn .NET, can I benefit from the MS discounts?

  - by Chris

  I quit high-school a couple of years ago and now I'm studying to get my diploma at a special course the EU created for people in my situation. This course is basically identical to normal high-school the only difference being fewer hours due to the fact that a lot of us have jobs(not me). I would like to learn windows development and .NET and I've seen around that they offer students some great discounts and even some free tools such as Visual Studio and Windows 7. I'm learning Java on Ubuntu at the moment but I'd like to move to .NET but can't afford Windows or other MS-related tools since I don't have a job and no real income. Can someone in my situation benefit from their offers?

• Samba network sharing NTFS drives and root permissions from local drives

  - by Bill

  I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.

• Text based game in XNA

  - by Sigh-AniDe

  I want to create a text based game, where the player will type up,down, left or right and the sprite will move in that direction. I created the game and at the moment the player moves with the up,left,down and right keys. I would like to change the movement of the sprite from keypresses to text commands, Ive googled a lot on creating text based games in XNA but have had no luck. Could you please help me or guide me in the right direction of how to do this in XNA. All help will greatly be appreciated. Thanks

• Pattern for performing game actions

  - by Arkiliknam

  Is there a generally accepted pattern for performing various actions within a game? A way a player can perform actions and also that an AI might perform actions, such as move, attack, self-destruct, etc. I currently have an abstract BaseAction which uses .NET generics to specify the different objects that get returned by the various actions. This is all implemented in a pattern similar to the Command, where each action is responsible for itself and does all that it needs. My reasoning for being abstract is so that I may have a single ActionHandler, and AI can just queue up different action implementing the baseAction. And the reason it is generic is so that the different actions can return result information relevant to the action (as different actions can have totally different outcomes in the game), along with some common beforeAction and afterAction implementations. So... is there a more accepted way of doing this, or does this sound alright?

• Look after your tribe of Pygmies with Java ME technology

  - by hinkmond

  Here's a game that is crossing over from the iDrone to the more lucrative Java ME cell phone market. See: Pocket God on Java ME Here's a quote: Massive casual iPhone hit Pocket God has parted the format waves and walked over to the land of Java mobiles, courtesy of AMA. The game sees you take control of an omnipotent, omnipresent, and (possibly) naughty deity, looking after your tribe of Pygmies... Everyone knows that there are more Java ME feature phones than grains of sand on a Pocket God island beach. So, when iDrone games are done piddlying around on a lesser platform, they move over to Java ME where things are really happening. Hinkmond

• How essential is it to make a service layer?

  - by BornToCode

  I started building an app in 3 layers (DAL, BL, UI) [it mainly handles CRM, some sales reports and inventory]. A colleague told me that I must move to service layer pattern, that developers came to service pattern from their experience and it is the better approach to design most applications. He said it would be much easier to maintain the application in the future that way. Personally, I get the feeling that it's just making things more complex and I couldn't see much of a benefit from it that would justify that. This app does have an additional small partial ui that uses some (but only few) of the desktop application functions so I did find myself duplicating some code (but not much). Just because of some code duplication I wouldn't convert it to be service oriented, but he said I should use it anyway because in general it's a very good architecture, why programmers are so in love with services?? I tried to google on it but I'm still confused and can't decide what to do.

• Switching from abstract class to interface

  - by nischayn22

  I have an abstract class which has all abstract methods except one which constructs objects of the subclasses. Now my mentor asked me to move this abstract class to an interface. Having an interface is no problem except with the method used to construct subclass objects. Where should this method go now? Also, I read somewhere that interfaces are more efficient than abstract classes. Is this true? Here's an example of my classes abstract class Animal { //many abstract methods getAnimalobject(some parameter) { return //appropriate subclass } } class Dog extends Animal {} class Elephant extends Animal {}

• Resolving a collision between point and moving line

  - by Conundrumer

  I am designing a 2d physics engine that uses Verlet integration for moving points (velocities mentioned below can be derived), constraints to represent moving line segments, and continuous collision detection to resolve collisions between moving points and static lines, and collisions between moving/static points and moving lines. I already know how to calculate the Time of Impact for both types of collision events, and how to resolve moving point static line collisions. However, I can't figure out how to resolve moving/static point moving line collisions. Here are the initial conditions in a point and moving line collision event. We have a line segment joined by two points, A and B. At this instant, point P is touching/colliding with line AB. These points have unit mass and some might have an initial velocity, unless point P is static. The line is massless and has no explicit rotational component, since points A and B could freely move around, extending or contracting the line as a result (which will be fixed later by the constraint solver). Collision is inelastic. What are the final velocities of the points after collision?

• How do I disable the global application menu?

  - by Michael Ekstrand

  I'm fairly excited for Unity, as it looks like a promising new direction for Ubuntu. However, I do have a concern - will it be possible to use Unity without the global menu? I have my window manager set to focus-follows-mouse/sloppy focus, and find the productivity gains to be immense. Sloppy focus is incompatible, however, with global menus, as it is possible for the focus to change while you move from window to menu. Will Unity support an option to use window menus while still using Unity?

• Child object free movement on Parent object

  - by The415

  Just to be straightforward, I am completely new to many aspects of coding and am searching for different specs and guidelines to aid me on my journey to crafting a wonderful game in Epic Games' Unreal Engine 4. Okay, I know upon viewing this, some may have little to no clue what I mean, so I'll put it like this to explain what I mean : Imagine a third person game with a simple model of a character. Now, say I have an object as a torso of a character in a game. Now Say I have an object as a head of the character. How could I keep the head as a child of the torso, but at the same time, allow it to move with the camera angle.

Booting flowing by normal till to login screen but if I move mouse cursor after that image immediately switch to console (without any error; only normal loading startup processes) and back to login screen. I can type my password and boot continuing loading but after few moment it again switch back to dark console and switch again to login screen. I can load recovery mode but if I try touch my cursor (by mouse or internal notebook touchpad) it again switch back to console and to login screen. But if I use only keyboard it work fine.

• How to improve programming skills?

  - by Mike

  I'm very new to programming. I started learning PHP about half a year ago, so I do know something. I can write small functions, I can export and import information from a database and I can make a website. I don't know OOP principles and I don't know about objects and classes. Should I move to OOP principles and learn about classes, methods and objects? If not, what should I do? Continue writing simple code? How can a programmer write his/her own API? Is OOP necessary to do this? So how can i improve my skills? I love programming. I spend my 24/7 on it, so any help will be appreciated.

• How should I handle using two databases with a legacy PHP application?

  - by Toby Allen

  I have a legacy PHP application that was written in 2004 and uses MSSQL as a database backend. At this stage MSSQL is still supported by PHP but only just via a Microsoft driver. I have looked at converting to mysql via automated tools, which work quite well, but I have quite complex views which need a lot of individual work to convert. I don't have a great deal of time to do this. Many tools I wish to use and frameworks I would like to move the application to, don't support MSSQL, so I was considering adding new features using a new mysql database and wondered if anyone had opinions on the pros and cons of using two seperate database backends in a single application?

• How to layout application icons in the panel?

  - by Vincenzo

  Hello everybody, Application and applets icons are changing their position or even disappears from the gnome-panel (see an example). It often happens after connecting to external monitor with different resolution setting, or sometimes happens by chance (I don't know what is the reason of such behaviour). Some icons I can move, others I can't. I don't know if they're locked or not. My question is: Is there any settings/software for icon's position control in the panel? I noticed that locking does not resolve this issue. Thank you for support.

• Dual monitor gnome-shell broke itself

  - by JXPheonix

  Ok, lets get this over with. I have a dual-monitor, ati setup on gnome-shell that was just fine until this morning. Then, this happened. Look closer... Whatever has happened to my ubuntu setup? My second monitor still works, entirely normally, with the exception that I cannot (obviously) access activities (as i am in gnome-fallback ). I do wish to resume my work... EDIT: By entirely normally, I mean I can move my mouse over it and have seperate windows on it and stuff. It's not mirroring. UPDATE: Unity works entirely normally.
