• Can there be an Environment that Reacts to Weather changes in-game?

  - 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. I had some recent thoughts about the possibility of creating an environment in a game that interacts with weather (Rain, Snow, Storms) Is it possible to make an environment that can simulate weather changes in a game? I wrote notes on this for weeks now. I was thinking that an increase on environments occlusion maps was necessary for creating the effect of rain on windows, as well as making a flowing liquid surface on windows that is only visible in rain. I was also considering the idea of additive bump-maps on meshes for snow, to simulate accumulation. Are these elements dynamic in Unreal 4? Can I implement them?

• Clone User Profile with Encrypted Home Folder

  - by doublerainbow64

  I'd like to clone my user profile on my local machine. I'd like to do so, just to keep all the preferences and not to have to redefine all of them manually. I've tried this, but when I login, it will just return to KDM login screen. BTW I'm using Kubuntu 14.04. What might be interesting: I have encrypted my home folder. Does this make any difference? I've also tried to copy the contents of .kde folder into /etc/skel, but this had no effect. Thank you very much in advance, doublerainbow64

• Cron doesn't execute one of the scheduled jobs

  - by user288633

  I'm using a lubuntu desktop, distribution Ubuntu 13.10, i686. This is my problem: in the job list scheduled by cron a job hasn't effect, but in /var/log/syslog its execution is traced. This is the relative log line: Jun 4 09:06:01 kiosk CRON[14189]: (root) CMD (/usr/bin/xinput set-prop 12 --type=float "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1 /tmp/mybackup.log) This job should rotate touchscreen mapping. I try different solutions: I substitute in crontab the with bash -c "", I set "export DISPLAY=:0.0" ("for Graphics related job in Unix Environment we need to set first the DISPLAY...") before the command,...and many other! I know there are a lots of details affect cron execution (path, environment variables, special character and other) and I have no more idea by now :( Could some gentleman suggest me an idea? where can I find the problem? Thanks in advance!

• As a programmer what single discovery has given you the greatest boost in productivity?

  - by ChrisInCambo

  This question has been inspired by my recent discovery/adoption of distributed version control. I started using it (mercurial) just because I liked the idea of still being able to make commits at times when I couldn't connect to the central server. I never expected it would give me a large boost in general productivity, but a pleasant side effect I discovered was that making a new clone every time I started a new task and giving that clone a descriptive folder name is extremely effective at keeping me on task resulting is a noticeable productivity increase. So as a programmer what single discovery has given you the greatest boost in productivity? Extra respect for answers which involve tools or practices that aren't so obvious from the outside!

• Faking Display tree (Sprite) parent child relationships with rasters (BitmapData) in ActionScript 3

  - by Arthur Wulf White

  I am working with Rasters (bitmapData) and blliting (copypixels) in a 2d-game in actionscript 3. I like how you can move a sprite and it moves all it's children, and you can simultaneously move the children creating an interesting visual effect. I do not want to use rotation or scaling however cause I do not know how that can be done without hampering with performance. So I'm not simulating Sprite parent-child behavior and sticking to the movement on the (x, y) axis. What I am planning to do is create a class called RasterContainer which extends bitmapData that has a vector of children of type Raster(extending bitmapData), now I am planning to implement recursive rendering in RasterContainer, that basically copyPixels every child, only changing their (x, y) offset to reflect their parent's offset. My question is, has this been implemented in an existing framework? Is this a good plan? Do I expect a serious performance hit for using recursive methods this way?

  I have below query: SET @sql = NULL ; SELECT GROUP_CONCAT( DISTINCT CONCAT( 'select latitude,longitude,max(serverTime) as serverTime,', deviceID, ' AS device from d', deviceID, '_gps' ) SEPARATOR ' UNION ALL ' ) INTO @sql FROM devices WHERE accountID =2; PREPARE stmt FROM @sql ; EXECUTE stmt; Can someone help me to write the above query in codeIgniter style.... ANd another thing is :What is the difference between writing the query in 1 and 2 formats 1. $query = $this->db->query('YOUR QUERY HERE'); 2. $this->db->select("..."); $this->db->from(); $this->db->where(); Will it have any effect on performance if we use 2nd style...

• Gparted not working in live CD (usb)

  - by alex

  Using ubuntu 10.10 live usb. When atempting to open gparted (sudo gparted in a terminal), its window gets stuck a few seconds and disappears (i noticed that it closes when it's searching for /dev/sda/ partitions). After a while a window appears telling gparted closed unexpectedly and asking to restart it. Choosing this option won't do any effect. Typing sudo fdisk -l in a terminal does show a list of the drives and partitons correctly. Any ideas? Thanks.

• Using apt-get from Canada

  - by Advant Edge

  I am using Ubuntu Server 12.04 LTS, and until yesterday, everything was quite peachy. I have installed several packages (MySQL, apache2) and to my knowledge have those configured correctly. Upon configuration of phpMyAdmin, I found that I was missing the directory path /etc/phpmyadmin, which got me thinking about the install. I am new to Ubuntu, so I guess I missed the message telling me that I did not download phpMyAdmin successfully. Anyway, trying to use apt-get yesterday/today results in "Failed to fetch..." messages, even if just to run sudo apt-get update. Some notable details: ···no GUI, command line only (sudo apt-get gksu fails, go figure) ···can ping 4.2.2.2, so I know the internet is out there (somewhere) ···this is a dedicated computer, using Samba to share files with Windows, which does work ···attempted to edit my /sources.list file, for various American/Canadian mirror, to no effect ···ensured I have correct DNS settings in /etc/networks/interfaces I'm not sure where along the way it happened, but I seem to have lost connections to repositories... :) Any advice (including GO BACK TO WINDOWS) is appreciated.

• Repelling a rigidbody in the direction an object is rotating

  - by ndg

  Working in Unity, I have a game object which I rotate each frame, like so: void Update() { transform.Rotate(new Vector3(0, 1, 0) * speed * Time.deltaTime); } However, I'm running into problems when it comes to applying a force to rigidbodies that collide with this game objects sphere collider. The effect I'm hoping to achieve is that objects which touch the collider are thrown in roughly the same direction as the object is rotating. To do this, I've tried the following: Vector3 force = ((transform.localRotation * Vector3.forward) * 2000) * Time.deltaTime; collision.gameObject.rigidbody.AddForce(force, ForceMode.Impulse); Unfortunately this doesn't always match the rotation of the object. To debug the issue, I wrote a simple OnDrawGizmos script, which (strangely) appears to draw the line correctly oriented to the rotation. void OnDrawGizmos() { Vector3 pos = transform.position + ((transform.localRotation * Vector3.forward) * 2); Debug.DrawLine(transform.position, pos, Color.red); } You can see the result of the OnDrawGizmos function below: What am I doing wrong?

• Do navigation menu links negatively impact SEO for pages' content?

  - by Rodolfo

  I've always had my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4

  - by danbystrom

  Beginner question. Synopsis: my water effects does something that causes the drawing of my sky sphere to throw an exeption when run in full screen. The exception is: XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4. This happens both when I start in full screen directly or switch to full screen from windowed. It does NOT happen, however, if I comment out the drawing of my water. So, what in my water effect can possibly cause the drawing of my sky sphere to choke???

• Need an engine for MMO mockup

  - by Kayle

  What I don't need is an MMORPG engine, at the moment. What I do need is a flexible easy-to-use engine that I can make a mock-up with. I don't need support for more than 10 players in an instance, so any multiplayer platform is probably fine. I need an engine with which I can create the following core features: Waves of simple AI enemies that have specific objectives (move to point A, destroy target, move to point B). The units present can be between 50-200 in number. An over-the-shoulder view and the ability to control a team of 3 (like Mass Effect or the latest Dragon Age) Functioning inventory system Right now, all I can really think of is Unreal or Source. Any other suggestions? Again, this is a proving mock-up, not an actual MMO. I'm not terribly worried about the visual aspects as we just want to test mechanics. Note: Can write some scripts in Python, Ruby, or Lua, if necessary.

• How to handle jumping up a slope in a runner game?

  - by you786

  In an 2D endless runner, what should happen when the player is running "too fast" up a slope and jumps? For example, in a "normal" case: .O. . __..O_____ . / . / O/ _/ If he is moving to the right slowly enough, he will jump upwards and land on the flat part of the surface. However, if he is moving too fast, the jump will have no effect as his forward motion will bring him back in contact with the slope before he can get high enough to pass over it. When the speed is sufficiently high, there will effectively be no jump. _________ / .O/ O/ _/ Are there any known ways to solve this issue? I know it's physically correct*, but are there techniques that other games use to overcome this in a reasonable manner? As a last resort I'll have to just remove all slopes that are too slanted. *If you constrain the player to never jumping backwards.

• How to make Facebook like button narrower than 225px?

  - by tog22

  I'm generating a like button with Facebook's 'standard' layout for my site via https://developers.facebook.com/docs/reference/plugins/like/ . I've set its width to 200 pixels, but notice that setting it to lower than 225 pixels has no effect, and the documentation on that page indeed specifies 225px as the minimum width for the standard layout. Unfortunately I need to make it 200 pixels wide to fit my site's design. Is there any way to force it into this width? (The site's at http://gwwc2.centreforeffectivealtruism.org/ if you want to have a play with Firebug, though the like button gets generated by javascript so you'd probably have to duplicate that page and edit its source.)

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?

• OcclusionQuery: how to ignore some objects?

  - by ApocKalipsS

  I'm trying to make a LensFlare effect when the player watch the sun in my XNA 4.0 Game. To do this, I use OcclusionQuery, here's my code: http://pastebin.com/meAkdwmD I also have some models, a terrain and a skybox. Here's my main Draw code: terrain.Draw(); model1.Draw(); model2.Draw(); skybox.Draw(); lensFlare.UpdateOcclusion(); lensFlare.Draw(); The problem is that the occlusion considers the sun to be behind the skybox, and the lensFlare wasn't showing up. So I moved lensFlare.UpdateOcclusion() before the drawing of the Skybox, and now the lensFlare appears, but my skybox is blinking (it's like it disappear and reappear at each frames...) How do I ignore the skybox in the occlusion?

• How to write loosely coupled classes in node.js

  - by lortabac

  I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

• How to disable low disk space notification? (Gnome 3, Ubuntu 12.04)

  - by grimripper

  I've got an SSD drive for root and /home, and a larger HDD for storage. The storage disk is almost full, and there's a low disk space warning on startup. The warning doesn't have any "don't show again" option, only "ignore" and "examine". It also doesn't go away but sticks on the screen until the ignore button is clicked, so it's very annoying in addition to being competely unnecessary. I tried unselecting the storage HDD in baobab's settings, but that didn't have any effect. I also tried gconf-editor, and looked for apps - gnome_settings_daemon - plugins - housekeeping, but there is no "plugins" under "gnome_settings_daemon". Only "gtk-modules" and "keybindings". Gnome 3.4.2.1 Ubuntu 12.04.1 LTS 64-bit

• Processing a list of atomic operations, allowing for interruptions

  - by JDB

  I'm looking for a design pattern that addresses the following situation: There exists a list of tasks that must be processed. Tasks may be added at any time. Each task is wholly independent from all other tasks. The order in which tasks are processed has no effect on the overall system or on the tasks themselves. Every task must be processed once and only once. The "main" process which launches the task processors may start and stop without warning. When stopped, the "main" process loses all in-memory data. Obviously this is going to involve some state, but are there any design patterns which discuss where and how to maintain that state? Are there any relevant anti-patterns? Named patterns are especially helpful so that we can discuss this topic with other organizations without having to describe the entire problem domain.

• Considerations for changing URL path

  - by Mandar

  I am having an e-commerce site and current URL structure is like this: www.example.com/category1 [Category landing page] www.example.com/category1/sub-category [sub-category listing page] www.example.com/category1/sub-category/product-name [Product Details page] I am finding it difficult to identify from the URLs whether the URL is category landing page or a listing page or a product details page (primarily in Google Analytics). To solve this problem, I am thinking of adding qualifiers in the URL as follows: www.example.com/category1/cat-land [Category landing page] www.example.com/category1/sub-category/cat-list [sub-category listing page] www.example.com/category1/sub-category/product-name/prod-details [Product Details page] Original URLs would be redirected to new URLs using 301 permanent redirect. Would this have any negative effect on existing SEO and Google ranking?

• How to display a projectile trajectory in c++? [on hold]

  - by sana

  I am trying to make a game of Gorillas in c++ whose specification is somewhat like....... is : "In this game both players should select their position on a level scaled ground. Scale of the ground should be from 0 to 20 divisions, each division corresponding to 10 meters. Each player will enter an angle and initial velocity (limits of both should be defined) and the player will hurl a stone with this velocity at given angle. Stone will make a projectile and if it hits the other player then shooting player wins. A random effect of air should also be incorporated. Air will support one player and resist other. Velocity of air should be generated randomly, within some limits, and subtracted or added in the horizontal velocity of the stone. An arrow of suitable length shall represent air direction and velocity. The player who hits first wins." How do I display the trajectory of the stone????

• When removing a bunch of files from a website, is 301 to the start page appropriate? [closed]

  - by Uwe Keim

  Possible Duplicate: What to do with random pages after a 301 redirect? Currently, we are working on modifying the contents of a website of one of our products. Since we are re-positioning the product, we would like to delete roughly 50% (around 200) of the pages of the website. My questions, in terms of SEO are: Would it have a negative effect if Google suddenly sees the large page drop? Is it OK to provide a 301 to the start page of the website for all removed pages?

• Get and set accessors do they protect different instances of a variable?

  - by Chris Halcrow

  The standard method of implementing get and set accessors in C# and VB.NET is to use a public property to set and retrieve the value of a corresponding private variable. Am I right in saying that this has no effect of different instances of a variable? By this I mean, if there are different instantiations of an object, then those instances and their properties are completely independent right? So I think my understanding is correct that setting a private variable is just a construct to be able to implement the get and set pattern? Never been 100% sure about this.
