  • How to Restore Uninstalled Modern UI Apps that Ship with Windows 8

    - by Lori Kaufman
    Windows 8 ships with built-in apps available on the Modern UI screen (formerly the Metro or Start screen), such as Mail, Calendar, Photos, Music, Maps, and Weather. Installing additional Modern UI apps is easy using the Windows Store, and uninstalling apps is just as easy. What if you accidentally uninstall a built-in app? It can be easily restored with a few clicks of your mouse. To begin, access the Modern UI screen by moving your mouse to the extreme, lower, left corner of the screen and click the Start screen button that displays. NOTE: You can also press the Windows key to access the Modern UI screen. How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?

  • Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work correcltly

    - by Dirk
    I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk PS: I could now install ubuntu with an external USB Keyboard/Mouse Set. But now, after showing the grub menu, a kernel panic error appears and booting stops :-/ Seems that the ubuntu images fit not to a macbook pro retina 13" (10,2) yet. PPS: Ok, there are new facts: If I edit the boot options and enter " nomodeset noapic" ubuntu starts and Keyboard and Touchpad work! Now I have to enable WiFi... PPPS: After installing Broadcom firmware from USB Live stick as described in other posts, WiFi was enabled. Then I could update ubuntu normally to 12.10. After this, I must not enter "nomodeset noapic" in the grub menu anymore. Last Thing now is the Touchpad. The driver seems not to be there. The touch pad is only showing as mouse. t.b.c.

  • Display problem with fresh install of 12.04

    - by Dan
    Just intalled Ubuntu 12.04 from CD and install went with no problems. After rebooting, I get the initial purple screen and then a black screen with mouse pointer and a few stray pixels at the bottom left of screen. Occasionally during the boot process, the purple screen comes back momentarily but then back to the black screen with the mouse pointer. When I finally give up and press the power button, the purple screen returns with the Shut Down box visible as it is shutting down. Any ideas? I have tried adding nomodeset after quiet splash, but no change. Possibly not doing it correctly, since I am somewhat of a newbie to linux. Thanks! Dan

  • 3D transformations in WPF & DirectX/Direct3D or OpenGL

    - by user2723417
    I need your help with 3D transformations. I have a sphere and I want to deform it by a mouse click or a mouse move. I want to make a furrow or to bite off a piece of the sphere without any breaks of 3D material. It is possible in WPF, but if the quantity of 3D points is more then 25 000, it creates some freezes in a dynamic mode (animation breaks), because the object of MeshGeometry3D class should be reconstructed every time to stop the breaks of 3D material. Give me advice about tools for the realization of my task. Maybe it can be done with the help of DirectX/Direct3D or OpenGL? I am a newcomer in these collections of APIs, but I would like to study them. I need to integrate the process of transformation in WPF application.

  • Ogre3D, OGRE_NEW gives editor errors

    - by automaticoo
    Hello Game Developers, I am trying to get more experienced with OGRE3D and I am following the basic tutorials on the website. All the code samples compile just fine. The first time I encountered a "error" was in Basic Tutorurial 3. The code line where visual studio says something is not right is : mTerrainGroup = OGRE_NEW Ogre::TerrainGroup(mSceneMgr, Ogre::Terrain::ALIGN_X_Z, 513, 12000.0f); Visual studio compiles this line but it shows a ugly red line beneath it and on mouse hover it says "#define OGRE_NEW new (FILE, LINE, FUNCTION) Error: no instance of overloaded 'operator new' matches the argument list" or if I mouse hover over Ogre::TerrainGlobalOptions() it says "Error: expected a type specifier". I searched on google but couldn't find my answer. I got about a year c++ experience but that was mainly with the WinSock libarys. Thanks in advance.

  • Ray-plane intersection to find the Z of the intersecting point

    - by Jenko
    I have a rectangle in 3d space (p1, p2, p3, p4) and when the mouse rolls over it I need to calculate the exact Z of the point on the rect, given the mouse coordinates (x, y). Would a Ray-plane intersection find the Z of the intersecting point? Edit: Would this one-liner work? .. it returns the t value for the intersection, apparently the Z value. float rayPlane(vector3D planepoint, vector3D normal, vector3D origin, vector3D direction){ return -((origin-planepoint).dot(normal))/(direction.dot(normal)); }

  • Problem on login: Freeze just before user selection

    - by Diego Garcia
    Hi, I'm using ubuntu 10.10 and when I login it shows my login's wallpaper an appears the window where I select my user without showing it and then gets frozen. No mouse response, no keyboard responde (even if I try to num/caps lock).

  • Configuring Multi-Tap on Synaptics Touchpad

    - by nunos
    I am having a hard time configuring my notebook's touchpad. The touchpad already works. It successfully responds to one-finger tap, two-finger tap and two-finger vertical scrolling. What I want to accomplish: change two-finger tap action from right-mouse click to middle-mouse click add three-finger tap functionality to yield right-mouse click action (i have checked that the three-finger tap is supported by my laptop's touchpad since it works on Windows) I read on a forum to use this as a guide. I have successfully accomplished point 1 with synclient TapButton2=2. However, I have to do it everytime I log in. I have tried to put that command on /etc/rc.local but the computer always boots and logins with the default configuration. Regarding point 2, I have tried synclient TapButton3=3 but it doesn't do anything when I three-finger tap the touchpad.

  • 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

    - by Lucy Dixon
    I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

  • Day 6 - Game Menuing Woes and Future Screen Sneak Peeks

    - by dapostolov
    So, after my last post on Day 5 I dabbled with my game class design. I took the approach where each game objects is tightly coupled with a graphic. The good news is I got the menu working but not without some hard knocks and game growing pains. I'll explain later, but for now...here is a class diagram of my first stab at my class structure and some code...   Ok, there are few mistakes, however, I'm going to leave it as is for now... As you can see I created an inital abstract base class called GameSprite. This class when inherited will provide a simple virtual default draw method:        public virtual void DrawSprite(SpriteBatch spriteBatch)         {             spriteBatch.Draw(Sprite, Position, Color.White);         } The benefits of coding it this way allows me to inherit the class and utilise the method in the screen draw method...So regardless of what the graphic object type is it will now have the ability to render a static image on the screen. Example: public class MyStaticTreasureChest : GameSprite {} If you remember the window draw method from Day 3's post, we could use the above code as follows...         protected override void Draw(GameTime gameTime)         {             GraphicsDevice.Clear(Color.CornflowerBlue);             spriteBatch.Begin(SpriteBlendMode.AlphaBlend);             foreach(var gameSprite in ListOfGameObjects)            {                 gameSprite.DrawSprite(spriteBatch);            }             spriteBatch.End();             base.Draw(gameTime);         } I have to admit the GameSprite object is pretty plain as with its DrawSprite method... But ... we now have the ability to render 3 static menu items on the screen ... BORING! I want those menu items to do something exciting, which of course involves animation... So, let's have a peek at AnimatedGameSprite in the above game diagram. The idea with the AnimatedGameSprite is that it has an image to animate...such as ... characters, fireballs, and... menus! So after inheriting from GameSprite class, I added a few more options such as UpdateSprite...         public virtual void UpdateSprite(float elapsed)         {             _totalElapsed += elapsed;             if (_totalElapsed > _timePerFrame)             {                 _frame++;                 _frame = _frame % _framecount;                 _totalElapsed -= _timePerFrame;             }         }  And an overidden DrawSprite...         public override void DrawSprite(SpriteBatch spriteBatch)         {             int FrameWidth = Sprite.Width / _framecount;             Rectangle sourcerect = new Rectangle(FrameWidth * _frame, 0, FrameWidth, Sprite.Height);             spriteBatch.Draw(Sprite, Position, sourcerect, Color.White, _rotation, _origin, _scale, SpriteEffects.None, _depth);         } With these two methods...I can animate and image, all I had to do was add a few more lines to the screens Update Method (From Day 3), like such:             float elapsed = (float) gameTime.ElapsedGameTime.TotalSeconds;             foreach (var item in ListOfAnimatedGameObjects)             {                 item.UpdateSprite(elapsed);             } And voila! My images begin to animate in one spot, on the screen... Hmm, but how do I interact with the menu items using a mouse...well the mouse cursor was easy enough... this.IsMouseVisible = true; But, to have it "interact" with an image was a bit more tricky...I had to perform collision detection!             mouseStateCurrent = Mouse.GetState();             var uiEnabledSprites = (from s in menuItems                                    where s.IsEnabled                                    select s).ToList();             foreach (var item in uiEnabledSprites)             {                 var r = new Rectangle((int)item.Position.X, (int)item.Position.Y, item.Sprite.Width, item.Sprite.Height);                 item.MenuState = MenuState.Normal;                 if (r.Intersects(new Rectangle(mouseStateCurrent.X, mouseStateCurrent.Y, 0, 0)))                 {                     item.MenuState = MenuState.Hover;                     if (mouseStatePrevious.LeftButton == ButtonState.Pressed                         && mouseStateCurrent.LeftButton == ButtonState.Released)                     {                         item.MenuState = MenuState.Pressed;                     }                 }             }             mouseStatePrevious = mouseStateCurrent; So, basically, what it is doing above is iterating through all my interactive objects and detecting a rectangle collision and the object , plays the state animation (or static image).  Lessons Learned, Time Burned... So, I think I did well to start, but after I hammered out my prototype...well...things got sloppy and I began to realise some design flaws... At the time: I couldn't seem to figure out how to open another window, such as the character creation screen Input was not event based and it was bugging me My menu design relied heavily on mouse input and I couldn't use keyboard. Mouse input, is tightly bound with graphic rendering / positioning, so its logic will have to be in each scene. Menu animations would stop mid frame, then continue when the action occured again. This is bad, because...what if I had a sword sliding onthe screen? Then it would slide a quarter of the way, then stop due to another action, then render again mid-slide... it just looked sloppy. Menu, Solved!? To solve the above problems I did a little research and I found some great code in the XNA forums. The one worth mentioning was the GameStateManagementSample. With this sample, you can create a basic "text based" menu system which allows you to swap screens, popup screens, play the game, and quit....basic game state management... In my next post I'm going to dwelve a bit more into this code and adapt it with my code from this prototype. Text based menus just won't cut it for me, for now...however, I'm still going to stick with my animated menu item idea. A sneak peek using the Game State Management Sample...with no changes made... Cool Things to Mention: At work ... I tend to break out in random conversations every-so-often and I get talking about some of my challenges with this game (or some stupid observation about something... stupid) During one conversation I was discussing how I should animate my images; I explained that I knew I had to use the Update method provided, but I didn't know how (at the time) to render an image at an appropriate "pace" and how many frames to use, etc.. I also got thinking that if a machine rendered my images faster / slower, that was surely going to f-up my animations. To which a friend, Sheldon,  answered, surely the Draw method is like a camera taking a snapshot of a scene in time. Then it clicked...I understood the big picture of the game engine... After some research I discovered that the Draw method attempts to keep a framerate of 60 fps. From what I understand, the game engine will even leave out a few calls to the draw method if it begins to slow down. This is why we want to put our sprite updates in the update method. Then using a game timer (provided by the engine), we want to render the scene based on real time passed, not framerate. So even the engine renders at 20 fps, the animations will still animate at the same real time speed! Which brings up another point. Why 60 fps? I'm speculating that Microsoft capped it because LCD's dont' refresh faster than 60 fps? On another note, If the game engine knows its falling behind in rendering...then surely we can harness this to speed up our games. Maybe I can find some flag which tell me if the game is lagging, and what the current framerate is, etc...(instead of coding it like I did last time) Sheldon, suggested maybe I can render like WoW does, in prioritised layers...I think he's onto something, however I don't think I'll have that many graphics to worry about such a problem of graphic latency. We'll see. People to Mention: Well,as you are aware I hadn't posted in a couple days and I was surprised to see a few emails and messenger queries about my game progress (and some concern as to why I stopped). I want to thank everyone for their kind words of support and put everyone at ease by stating that I do intend on completing this project. Granted I only have a few hours each night, but, I'll do it. Thank you to Garth for mailing in my next screen! That was a nice surprise! The Sneek Peek you've been waiting for... Garth has also volunteered to render me some wizard images. He was a bit shocked when I asked for them in 2D animated strips. He said I was going backward (and that I have really bad Game Development Lingo). But, I advised Garth that I will use 3D images later...for now...2D images. Garth also had some great game design ideas to add on. I advised him that I will save his ideas and include them in the future design document (for the 3d version?). Lastly, my best friend Alek, is going to join me in developing this game. This was a project we started eons ago but never completed because of our careers. Now, priorities change and we have some spare time on our hands. Let's see what trouble Alek and I can get into! Tonight I'll be uploading my prototypes and base game to a source control for both of us to work off of. D.

  • Alt-Tab in Unity 2D makes app icon jiggle instead of switching

    - by itsadok
    I'm using Unity 2D as my desktop, and it works fine most of the time, but every now and then, I try to Alt-Tab to switch to a different application, and instead of switching to that window, the launcher bar opens, and the icon of the application I was trying to switch to starts jiggling. If I try to switch to something else, that icon starts jiggling too. If I click on the icon with the mouse, then it stops jiggling and switches to the requested window. What is this behavior? I haven't seen any mention of jiggling icons in Unity. I don't understand the original purpose of this, and I'd like a way to fix it so that I won't have to use the mouse.

  • Direction of the bullet - how to have something else than left, right, top, bottom

    - by Florian Margaine
    I'm making a simple shooter game using canvas and javascript. The current code can be seen here. To know which way I want the bullet to be shot, I simply have a direction property that can have 4 values (left, right, bottom, top), and I can then calculate the next position of the bullet easily. However, I'd like to move the bullet to the mouse position, but I don't really see how to do this. How do I calculate the next position? I'm guessing there is some formula to calculate the line between two positions (the player's and the mouse's), but I don't have much idea yet. So there is no obstacle, but I don't see how to calculate this, and be able have the next position of the bullet at each frame.

  • How to autohide Unity 2D?

    - by ph1b
    In the regular Unity 3D, I used Compiz Config Manager where I could config the Unity-Plugin to autohide the left start-bar and not to show it when moving my mouse to the left. So it was perfect for using Docky. But with Unity 2D the Unity settings don't have any effect. How can I completely hide the start-panel and just have it shown when pressing the windows-key? With the following: dconf write /com/canonical/unity-2d/launcher/hide-mode 1 dconf write /com/canonical/unity-2d/launcher/use-strut false it still opens the bar when going with my mouse to the left.

  • Ubuntu on AMD based Sony Vaio VPCY B15AG

    - by Gaurav
    Last week I bought a AMD E350 (AMD Fusion platform) based Sony VAIO (VPCYB15AG) having AMD Radeon HD 6310 graphics, I removed Windows that came along with and installed Ubuntu 10.10 (AMD64) using USB drive. During installation my touchpad was not working, I managed through keyboard, but after completing installation & restarting the machine still there was no touchpad support. Also there's no proper graphic card drivers. Even I tried connecting the USB mouse to it but the left key is not working and had to configure the mouse as left-hand to get the left click enabled. I tried searching for any possible solutions for these but found nothing helpful, is there any hope? What should I do to enable i) enable touch pad support ii) get higher resolution 1366x768, etc?

  • IP address from a MAC address

    - by acermate433s
    I'm writing a class to integrate a POS card reader device to our software. In order for it to work I must know what IP it's using. We were given some sample code by the service provider and the way they do this is they open a website (http://www.ebizchargeemv.com/getip.php?mac={MAC address of device}) and it would return the IP address of the device. The device I'm using is a POSLynx220 Mini. It has an ethernet port that connects to the internet to communicate with the service provider. I send TCP data to it and the device then controls a PIN pad that prompts a client to swipe his card. It's probably a mini computer that communicates with the service provider and uses the PIN pad as its input device. Just being curious but how did they implement this? Are they implementing it using ARP? I'm planning on not using their website to determine the IP of the device. I've seen some code that uses ARP but using executing ARP in one of the PC didn't detect the POS device.

  • 12.04 How do I disable the long press Super key from showing the shortcuts window?

    - by pt123
    Note this is the long press and not the one for the short press as mentioned here How do I disable the Super key? The super key has been a modifier long before Unity came, and I have used it on Compiz Zoom feature. So holding super down and moving the mouse scroll would zoom in and out the screen. But now in 12.04 the shortcut list screen pops up and it is irritating. I have also tried changing the keys to control +super + mouse scroll and a similar thing happens. Is there anyway to disable or change the long press super key for this, I have searched Compiz Unity plugin, the Systems Preferences - Keyboard shortcuts settings and haven't been able to find this.

  • Switch encoding of terminal with a command

    - by Tomas Lycken
    One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that). I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly. The change I need to do can be performed using the mouse by navigating to "Terminal"-"Set Character Encoding..."-"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen? To clarify: I'm not interested in ways of switching the locale of the system on the remote site - that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

  • How to disable touchpad while using trackpoint on a Thinkpad?

    - by January
    Thinkpads (e.g. X230 that I'm using) have both a trackpoint and a touchpad. The touchpad is disabled when typing. However, when I'm using the trackpoint, I often touch the touchpad as well, and generate mouse clicks I'd like to avoid. Does anyone have an idea how disable mouse-clicks on touchpad when trackpoint is in use? EDIT: also, can someone explain how the option of disabling touchpad when typing works? What is being done behind the scenes? Is it an xinput configuration command, and if yes, which one?

Ok so i have been following this tutorial, but im not using glm, ive been implementing everything up until now, like lookat etc. http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_Arcball So i can rotate with the click and drag of the mouse, but when i rotate 90º degrees around Y and then move the mouse upwards or donwwards, it rotates on the wrong axis, this problem is demonstrated on this part of the tutorial An extra trick is converting the rotation axis from camera coordinates to object coordinates. It's useful when the camera and object are placed differently. For instace, if you rotate the object by 90° on the Y axis ("turn its head" to the right), then perform a vertical move with your mouse, you make a rotation on the camera X axis, but it should become a rotation on the Z axis (plane barrel roll) for the object. By converting the axis in object coordinates, the rotation will respect that the user work in camera coordinates (WYSIWYG). To transform from camera to object coordinates, we take the inverse of the MV matrix (from the MVP matrix triplet). What i have to do acording to the tutorial is convert my axis_in_camera_coordinates to object coordinates, and the rotation is done well, but im confused on what matrix i use to do just that. The tutorial talks about converting the axis from camera to object coordinates by using the inverse of the MV. Then it shows these 3 lines of code witch i havent been able to understand. glm::mat3 camera2object = glm::inverse(glm::mat3(transforms[MODE_CAMERA]) * glm::mat3(mesh.object2world)); glm::vec3 axis_in_object_coord = camera2object * axis_in_camera_coord; So what do i aply to my calculated axis?, the inverse of what, i supose the inverse of the model view? So my question is how do you transform camera axis to object axis. Do i apply the inverse of the lookat matrix? My code: if (cur_mx != last_mx || cur_my != last_my) { va = get_arcball_vector(last_mx, last_my); vb = get_arcball_vector( cur_mx, cur_my); angle = acos(min(1.0f, dotProduct(va, vb)))*20; axis_in_camera_coord = crossProduct(va, vb); axis.x = axis_in_camera_coord[0]; axis.y = axis_in_camera_coord[1]; axis.z = axis_in_camera_coord[2]; axis.w = 1.0f; last_mx = cur_mx; last_my = cur_my; } Quaternion q = qFromAngleAxis(angle, axis); Matrix m; qGLMatrix(q,m); vi = mMultiply(m, vi); up = mMultiply(m, up); ViewMatrix = ogLookAt(vi.x, vi.y, vi.z,0,0,0,up.x,up.y,up.z);

  • The menu in the titlebar disappears in 12.10

    - by kinsago
    When running various programs (as I write this, with Chrome & Evolution) I move my mouse to the title bar to access the menu. The menu only seems to appear if I target the buttons to the left. When I move the mouse off the buttons (but still on the title bar) to select a menu then most times the menu disappears. It would seem this only happens on of my displays (of which I have 2) and it is the display that has the unity menu on it. Any ideas?

  • External USB 3 drive not recognized

    - by ilan123
    Ubuntu 12.10 64 bit seems not to recognize my external hard disk. It is a Vantec NST-310S3 external disk enclosure with a WD 3TB drive. The disk has two NTFS partitions. My PC is a dual boot system. Under Windows 7 the hard disk works fine but I can't make it work with Ubuntu. When the drive is connected to the PC then the command sudo fdisk -l seems to hang forever. Below are the output of lsusb and cat /proc/partitions without the external drive and then with it connected. I added also the last lines of the dmesg command at the end.

  • Preventing RSI (Repetitive Strain Injuries)

    - by nightcracker
    I am 16 years old and I love to program and playing the piano. It's not uncommon that I'm bashing away on my mouse and keyboard all day long. I do not feel any pains doing so. Yet I am still worried, because I often hear from people that they can never type for longer then 10 minutes again without getting severe pains. Given my two hobbies, programming and playing the piano that worries me a lot. My current situation is this: G15 keyboard and G5 mouse A chair that looks like this (the back of the chair is surprisingly supportive): http://www.ikea.com/nl/nl/images/products/torbjorn-bureaustoel__0084333_PE210956_S4.JPG In my "normal sitting position" the table is around the height of my bellybutton. A LG Flatron L194wt screen (too small IMO, getting a new one soon) Should I be worrying about RSI/similar health issues? If yes, what can/should I do about it?

  • Why does my sprite glitch when moving? [closed]

    - by rphello101
    Using Slick 2D/Java, I'm using the mouse to rotate a sprite and WASD to move it (A and D are used to strafe). I finally got the directional keys and rotation to work in sync, but I'm having problems with sporadic movement. It seems that the move speed is not always set to the value I have it at. Sometimes the sprite with just shoot across the screen. Furthermore, it seems that at 0 degrees, when the left key is pressed, the sprite moves backwards, not to the left. There also seems to be quite a bit of glitching when two keys are pressed, like left and up. Anyone see anything obvious? Here is the rotational code: int mX = Mouse.getX(); int mY = HEIGHT - Mouse.getY(); int pX = sprite.x+sprite.image.getWidth()/2; int pY = sprite.y+sprite.image.getHeight()/2; double mAng; if(mX!=pX){ mAng = Math.toDegrees(Math.atan2(mY - pY, mX - pX)); if(mAng==0 && mX<=pX) mAng=180; } else{ if(mY>pY) mAng=90; else mAng=270; } sprite.angle = mAng; sprite.image.setRotation((float) mAng); Movement code: Input input = gc.getInput(); Vector2f direction = new Vector2f(); Vector2f velocity = new Vector2f(); Vector2f left; Vector2f right; direction.x = (float) Math.cos(Math.toRadians(sprite.angle)); direction.y = (float) Math.sin(Math.toRadians(sprite.angle)); if(direction.length()>0) direction = direction.normalise(); left = new Vector2f(-direction.y, direction.x); right = new Vector2f(direction.y, -direction.x); velocity.x = (float) (direction.x * sprite.moveSpeed); velocity.y = (float) (direction.y * sprite.moveSpeed); if(input.isKeyDown(sprite.up)){ sprite.x += velocity.x*delta; sprite.y += velocity.y*delta; }if (input.isKeyDown(sprite.down)){ sprite.x -= velocity.x*delta; sprite.y -= velocity.y*delta; }if (input.isKeyDown(sprite.left)){ sprite.x += left.x * sprite.moveSpeed * delta; sprite.y += left.y * sprite.moveSpeed * delta; }if (input.isKeyDown(sprite.right)){ sprite.x += right.x * sprite.moveSpeed * delta; sprite.y += right.y * sprite.moveSpeed * delta; }
