• Render 2D textures on a 3D object's face

  - by www.Sillitoy.com

  I am not familiar with 3D graphics, and I'd like to know the right way to render some 2D figures on different points of a wider face of a 3D object. My 3D object is just a cube representing a poker table. I have a 2D png for players' placeholders, and I'd like to render these figures on the 3D object where needed. An alternative solution would be to render the whole face with a big picture containing all the placeholders figures. However, it would be a waste of memory and thus less efficient. What do you suggest?

• Dual displays not working with Xinerama in Ubuntu 12.04

  - by user68489

  I just upgraded from Ubuntu 10.10 to 12.04. I had been using a display configuration just like the one described at http://bitkickers.blogspot.com/2009/08/rotate-just-one-monitor-with.html without any problems under 10.10. I have an nvidia Quadro FX 380 and have upgraded to the latest drivers (295.49). Everything appears to be fine when the system first boots up. However, after logging in, the left screen goes black, and the right screen displays what should be displayed on the left screen. Logging into Ubuntu 2D somewhat improves things. The left screen correctly displays the left portion of the desktop but the right screen contains a duplicate view of the left screen. Turning off Xinerama and enabling TwinView appears to fix the issues but does not allow the right monitor to be rotated. Since the display problems start to occur only after logging on, I thought it might have to do with carryover user configuration from 10.10 but the problems persist even when logging in as a guest. Clicking on System Settings - Displays results in the error message "Could not get screen information - RANDR extension is not present." Any help would be greatly appreciated.

• How to prioritize related game entity components?

  - by Paul Manta

  I want to make a game where you have to run over a bunch of zombies with your car. When moving around, the zombies have a few things to take into consideration: When there's no player around they might just roam about randomly. And even when some other component dictates a specific direction, they should wobble to the left and right randomly (like drunk people). This implies a small, random, deviation in their movement. They should avoid static obstacles. When they see they are headed towards a wall, they should reorient themselves. They should avoid the car. They should try to predict where the car will be based on its velocity and try to move out of the way. When they can, they should try to get near the player. All these types of decisions they have to do seem like they should be implemented in different components. But how should I manage them? How can I give different components different weights that reflect the importance of each decision (in a given situation)? I would need some other component that acts as a manager, but do you have any tips on how I should implement it? Or maybe there's a better solution?...

• Rotate a vector relative to itself

  - by Paul Manta

  I have a plane defined by transform.forward and transform.right, with 0 degrees corresponding to the forward vector and positive 90 degrees to the right vector. How can I create a third vector rotated in this plane. A rotation of 0 degrees would mean the vector is identical to transform.forward, a rotation of 30 degrees would mean it forms a 30 degree angle with the forward vector. In other words, I want to rotate the forward vector relative to itself, in the plane it defines with the right vector.

• Ubuntu 12.04 freezing on startup

  - by Frank

  Have been looking everywhere to find a solution to this problem but have yet to find a solution. I am running 64 bit 12.04 LTS on a AMD C-50 Dual core 6 gigs ram AMD Ratheon HD 6250. The problem I am experiencing is when ubuntu gets to the wallpaper screen it will sometimes freeze soon after the the image appears or shortly there after gnome loads locking up keyboard and mouse. When I try to log in via the console the same thing happens (this is as ubuntu is loading). At the moment the system is set to auto login previously it was set to ask for password but it did the same thing. Switching to from lightdm to gdm did nothing to alleviate the issue. I have never had so many issues with ubuntu I have to say 12.04 is the most buggy version yet.

• Disable Dash Home Shortcut in 12.04

  - by kunigami

  I'm using Ubuntu 12.04 in VirtualBox on a MacBook. The current shortcut for the dash home launcher is the Command key (Super). I'm trying to disable it. First, this option is not present in the shortcuts preferences. I have already tried: Changing it through gconf-editor Changing it through ccsm Even though when I press Super or Super+F it still launches the dash home. Any ideas on what I can still try?

• New Endpoint options that enable additional application patterns

  - by kaleidoscope

  The two communication-related capabilities:  a) inter-role communication and b) external endpoints on worker roles enable new application patterns in Windows Azure-hosted services. Inter-role Communication - A common application pattern enabled by this is client-server, where the server could be an application such as a database or a memory cache. External Endpoints on Worker Roles - A common application type enabled by this is a self-hosted Internet-exposed service, such as a custom application server.

• Window controls appearing on the right side after updating to 12.10 [closed]

  - by Ankit

  Possible Duplicate: Window buttons stuck on right side After updating from Ubuntu 12.04 to 12.10 the window controls(min, max, close) have started appearing on the right side when the window is not maximized, they again come on the left side when the window is maximized. I tried changing it using Ubuntu Tweak, but with no effect. Other suggestion I found was to change it using gconf-editor and changing apps - metacity - general click button_layout but there is no metacity in the apps section.

• Drupal 7: Documents as a node/block/field

  - by WernerCD

  I'm working on my first Drupal site. I've progressed in learning the basics . I still have a lot to learn tho. Using FileViewer I can load a PDF saved in a field, for view content of various types. I haven't found something that does the same for Word Docs, Excel, PDF, etc. Does anyone know of something that works in Drupal 7 to load documents other than PDF like FileViewer does inside a browser? Or like Scribd does (Scribd is hosted. I am behind a firewall with limited access for users. So I don't want to use a Scribd like service.)

• block access to certain website types

  - by frustrated teacher

  Need to block access to certain website types without listing each URL to block. Students at secondary school are going to porn sites. Need to be able to block all such access without having to list each possible site URL. Having the Content -- Ratings tab set to None for all categories on the ratings files listed on my computers does not prevent access. Unchecking users may access sites with no rating, even with the security settings set to High, still allows the porn sites to come up. If that is checked, then ONLY listed sites can open and students would not be able to do any research via google, for example. I would rather not have to continue checking each computer and blocking sites as they find them.

• Missing launcher, top panel without icons, an ATI driver problem?

  - by jlotero

  After upgrading to Ubuntu 11.10, the following problems occurs when accesing in ubuntu mode (3D): the launcher is missing, top panel without icons on the right side, and I can only restart with Terminal (Alt-T and then sudo reboot). No problems in 2D. It occurs on my PC with AMD Athlon (tm) II X4 640 Processor, Radeon HD5670 and both with the 32-bit and 64 bits versions of Ubuntu. Both versions work well on an older PC with AMD Athlon 64 x2 Dual Core 4200 + processor, and an Nvidia integrated graphics card (C61 GeForce 6150SE nForce 430). Could it be a problem with the ATI driver?

• Is it possible to have my desktop loaded before login?

  - by Dims

  I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?

• How Would I create alternate players (Turn base Event)

  - by Blue

  The picture above shows 2 players. Each containing 3 characters. I want to know how to make a Turn based event starting with player 1 alternating turns with player 2. And in every alternation each character gets a turn. If a character dies, the next character on the same team goes, and so on. How would I create this? Is there a tutorial? I haven't made any turn-based games so I don't know how to program these kinds of stuff.

• Hidden Launch Bar wouldn't slide-out when moused over, now it won't hide away.

  - by Dave Keller

  When the launch bar is hidden, I have trouble getting it to slide out when I move the mouse pointer to the left side. After adjusting the settings under Settings--Appearance--Behavior, the bar no longer hides when a browser is open. Is there a fix for this. This all happened when I was looking for a way to change the icon sizes in the launch bar. Documentation from Linux.com told me to do it under Settings--Appearance, but there was no way to do it. Any help is appreciated! Thanks.

• two guitexture that do not work together

  - by London2423

  I have two GUITexture that move left and right a cube. Is pretty strange but together they don't work. If I activate only one it works. To be more specific: If I have the left GUItexture alone in the game the cube move left. If I have the right GUITexture activated alone the cube move right. Seems all fine I thought but If I have both of them the cube move only right and not left. Where is the mistake? Here is the code inside the GameObject cube for Right move void OnMousedown () { transform.position += Vector3.right * Time.deltaTime; } For Left move void OnMousedown () { transform.position += Vector3.left * Time.deltaTime; } And this is the left GUITexture code //move the cube left Cube.GetComponent<Left> ().enabled = true; left.transform.position += Vector3.left * Time.deltaTime; This is the right GUITexture //move the cube right Cube.GetComponent<Left> ().enabled = true; right.transform.position += Vector3.right * Time.deltaTime; What is the reason for this? I hope someone can help me.

• Privoxy rule to block Facebook spying

  - by bignose

  Recently, my server's Privoxy rules to block Facebook's spying have failed. How can I block current Facebook spying links? Since soon after [the inception of Facebook's so-called “Open Graph” cross-site tracking widgets][1] (those “Like” bugs on numerous websites), I blocked them by using this rule (in user.action) on our site's Privoxy server: { +block-as-image{People-tracking button.} } .facebook.com/(plugins|widgets)/(like|fan).* That worked fine; the spying bugs no longer appeared on any web page. Today I noticed that they're all making it past that filter [edit: no, they're not]. SOLUTION: The proxy was being silently ignored, though this was not obvious in the client. The above rule continues to work fine.

• Scrolling background with changing textures

  - by Simran kaur

  I have the 2 cubic structures that are my tracks and are scrolling basically to give effect of movement on object. In my OnBecameInvisible() method, I have changed their Tiling using mainTextureScale void OnBecameInvisible() { renderer.material.mainTextureScale = new Vector2(1, numberOfLanes); this.transform.position = new Vector3(this.transform.position.x, this.transform.position.y, 20.0f); } The tiling works fine. But the alternative tracks have their Tiling set to 0 which is giving an undesirable effect. Requirement: I want to be able to set the Tiling of every track that is visible on the screen. How do I do it?

• Ubuntu 12.10 Network Connection menu GUI doesnt work properly

  Many a times I have seen When I click on network connection(besides volume icon), I am unable to select any options. When I hover over VPN connections, the list shows nothing. I have added many VPNs. Network menu becomes non responsive to any clicks. This is annoying because I am not able to connect to any of the VPN connections. "Enable Wireless", "Edit Connections" or any other option doesnt work at all. Restarting ubuntu fixes this issue. But problem starts randomly again and restarting my laptop is the only way to fix it. Is this a known bug? Any ways to fix this prob?

• Dynamic Components

  - by Alex

  I am attempting to design a component-based architecture that allows Components to be dynamically enabled and disabled, much like the system employed by Unity3D. For example, all Components are implicitly enabled by default; however, if one desires to halt execution of code for a particular Component, one can disable it. Naively, I want to have a boolean flag in Component (which is an abstract class), and somehow serialize all method calls into strings, so that some sort of ComponentManager can check if a given Component is enabled/disabled before processing a method call on it. However, this is a pretty bad solution. I feel like I should employ some variation of the state paradigm, but I have yet to make progress. Any help would be greatly appreciated,
