  • Must double-tap Windows key to open Dash

    - by Bart van Heukelom
    I'm experiencing some strange behaviour of the Unity Dash and the Windows/Super keyboard key. As far as I know, normal behaviour is: Tap: Open Dash Hold: Show keyboard shortcut overlay However, the behaviour I'm experiencing is: Tap: Show keyboard shortcut overlay (after a short delay) Double Tap: Open Dash Hold: Show keyboard shortcut overlay What could cause this, and how do I fix it? I'm on a fresh 12.10 (Quantal) installation.

  • Map format for 3d open world

    - by Pacha
    I am making an open world 3d platformer in Ogre3D, and I have no idea on what kind of 3d map file format I should use for it. I want to make low-polygon blocky-style objects. Probably rectangles and other geometrical figures that don't have circular edges. Some of those blocks will have properties, like climbable or they might move. I was wondering what would be the best thing to do to make the map (just one level, as it is open).

  • How to clean and add options to the Open With list of apps

    - by Luis Alvarado
    After installing several PPAs (Wine, PoL) and opening several files with other apps (Like changing from Totem to VLC) I discovered that the Open With option had 2 problems: Many items on the list are duplicated (As seen on the image for "A Wine Program") Sometimes the app I want to use to open is not shown there (For example, Virtualbox or VLC) So how can I edit this list to clean the duplicates and add missing apps from the list.

  • Set Ctrl+Alt+T to open a maximized terminal

    - by queueoverflow
    I use the Ctrl+Alt+T shortcut to open a terminal, but I cannot see how I can get it maximized. When I start it manually, I can simply do a gnome-terminal --maximize, but that does not apply for the shortcut. Even a changing of the .desktop files did not change anything. Any way to let the shortcut open a maximized terminal window? I use regular Gnome 2 on Ubuntu 11.04 with no compositing effects.

  • Yet another frustum culling question

    - by Christian Frantz
    This one is kinda specific. If I'm to implement frustum culling in my game, that means each one of my cubes would need a bounding sphere. My first question is can I make the sphere so close to the edge of the cube that its still easily clickable for destroying and building? Frustum culling is easily done in XNA as I've recently learned, I just need to figure out where to place the code for the culling. I'm guessing in my method that draws all my cubes but I could be wrong. My camera class currently implements a bounding frustum which is in the update method like so frustum.Matrix = (view * proj); Simple enough, as I can call that when I have a camera object in my class. This works for now, as I only have a camera in my main game class. The problem comes when I decide to move my camera to my player class, but I can worry about that later. ContainmentType CurrentContainmentType = ContainmentType.Disjoint; CurrentContainmentType = CamerasFrustrum.Contains(cubes.CollisionSphere); Can it really be as easy as adding those two lines to my foreach loop in my draw method? Or am I missing something bigger here? UPDATE: I have added the lines to my draw methods and it works great!! So great infact that just moving a little bit removes the whole map. Many factors could of caused this, so I'll try to break it down. cubeBoundingSphere = new BoundingSphere(cubePosition, 0.5f); This is in my cube constructor. cubePosition is stored in an array, The vertices that define my cube are factors of 1 ie: (1,0,1) so the radius should be .5. I least I think it should. The spheres are created every time a cube is created of course. ContainmentType CurrentContainmentType = ContainmentType.Disjoint; foreach (Cube block in cube.cubes) { CurrentContainmentType = cam.frustum.Contains(cube.cubeBoundingSphere); ///more code here if (CurrentContainmentType != ContainmentType.Disjoint) { cube.Draw(effect); } Within my draw method. Now I know this works because the map disappears, its just working wrong. Any idea on what I'm doing wrong?

  • Code Design question, circular reference across classes?

    - by dsollen
    I have no code here, as this is more of a design question (I assume this is still the best place to ask it). I have a very simple server in java which stores a mapping between certain values and UUID which are to be used by many systems across multiple platforms. It accepts a connection from a client and creates a clientSocket which stores the socket and all the other relevant data unique to that connection. Each clientSocket will run in their own thread and will block on the socket waiting for a read. I expect very little strain on this system, it will rarely get called, but when it does get a call it will need to respond quickly and due to the risk of it having a peak time with multiple calls coming in at once threaded is still better. Each thread has a reference to a Mapper class which stores the mapping of UUID which it's reporting to others (with proper synchronization of course). This all works until I have to add a new UUID to the list. When this happens I want to report to all clients that care about that particular UUID that a new one was added. I can't multicast (limitation of the system I'm running on) so I'm having each socket send the message to the client through the established socket. However, since each thread only knows about the socket it's waiting on I didn't have a clear method of looking up every thread/socket that cares about the data to inform them of the new UUID. Polling is out mostly because it seems a little too convoluted to try to maintain a list of newly added UUID. My solution as of now is to have the 'parent' class which creates the mapper class and spawns all the threads pass itself as an argument to the mapper. Then when the mapper creates a new UUID it can make a call to the parent class telling it to send out updates to all the other sockets that care about the change. I'm concerned that this may be a bad design due to the use of a circular reference; parent has a reference to mapper (to pass it to new ClientSocket threads) and mapper points to parent. It doesn't really feel like a bad design to me but I wanted to check since circular references are suppose to be bad. Note: I realize this means that the thread associated with whatever socket originally received the request that spawned the creation of a UUID is going to pay the 'cost' of outputting to all the other clients that care about the new UUID. I don't care about this; as I said I suspect the client to receive only intermittent messages. It's unlikely for one socket to receive multiple messages at one time, and there won't be that many sockets so it shouldn't take too long to send messages to each of them. Perhaps later I'll fix the fact that I'm saddling higher work load on whatever unfortunate thread gets the first request; but for now I think it's fine.
