• What is w componet [duplicate]

  - by Tifa

  This question already has an answer here: What does the graphics card do with the fourth element of a vector as the final position? 3 answers What is the W component on graphics programming. I read a blog about opengl that says that w must be equal to either 0 or 1 here. But the book I am currently reading has put w component to more than 1 value. So im kinda confuse what does it really do. The book I am reading is OpenGL es a quick start guide.

• Cycling through ItemStacks whlie supplying data... LOST [on hold]

  - by user3251606

  Ok so i am working on a plugin for my server that will open and inventory and when closed it will pass items to this class... object of this class is to cycle through the inventory and use a cfg file to define items and prices and then grab that info in a for loop and add it all up... heres what i have thus far... public void sell(Player p, Inventory inv) { ListIterator<ItemStack> it = inv.iterator(); double total = 0; for (ItemStack is : inv) { is = it.next(); if (is.getType() != null) { String type = is.getType().toString(); //short dur = is.getDurability(); String check = ChestSell.plugin.getConfig().getString(type); p.sendMessage("Item Type: " + type); if (check != null) { int amou = is.getAmount(); double value = ChestSell.plugin.getConfig().getDouble(type + ".price"); double tv = amou * value; p.sendMessage("Items in chest: Type " + type + " Ammount: " + amou + " Value: $" + tv); } //TODO Add return Items } } p.sendMessage("You got paid $" + total + " for your items!"); inv.clear(); }

• TexturePacker ignores extensions

  - by The Oddler

  I'm using TexturePacker in one of my games, though when packing a bunch of textures their extension is kept in the data file. So when I want to find a texture I need to search for "image.png" instead of just "image". Is there an option to let texture packer ignore the extensions of my source images in the data file? Solved: So if anyone else wants this, here's the exported I made: https://www.box.com/s/bf12q1i1yc9jr2c5yehd Just extract it into "C:\Program Files (x86)\CodeAndWeb\TexturePacker\bin\exporters\UIToolkit No Extensions" (or something similar) and it should show op as an exporter.

• Sprite batching seems slow

  - by Dekowta

  I have implemented a sprite batching system in OpenGL which will batch sprites based on their texture. How ever when I'm rendering ~5000 sprites all using the same texture i'm getting roughly 30fps. The process is as followed create sprite batch which also create a VBO with a set size and also creates the shaders as well call begin and initialise the render mode (at the moment just setting alpha on) call Draw with a sprite. This checks to see if the texture of the sprite has already been loaded and if so it just creates a pointer to the batch item and adds the new sprite coords. If not then it creates a new batch item and adds the sprite coords to that; it adds the batch item to the main batch. if the max sprite count is reached render will be called call end which calls render to render the left over sprites in the batch. and also resets the buffer offset render loops through each item in the batch and will bind the texture of the batch item, map the data to the buffer and then draw the array. the buffer will then be offset by the amount of sprites drawn. I have a feeling that it could be the method i'm using to store the batched sprites or it could be something else that i'm missing but I still can work it out. the cpp and h files are as followed http://pastebin.com/ZAytErGB http://pastebin.com/iCB608tA On top of this i'm also getting a weird issue where then two sprites are batched on after the other the second sprite will use the same coordinates as the last. And then when one if drawn after it is fine. I can't seem to find what is causing this issue. any help would be appreciated iv been sat trying to work this all out for a while now and cant seems to put my finger on what's causing it all.

• Function for building an isosurface (a sphere cut by planes)

  - by GameDevEnthusiast

  I want to build an octree over a quarter of a sphere (for debugging and testing). The octree generator relies on the AIsosurface interface to compute the density and normal at any given point in space. For example, for a full sphere the corresponding code is: // returns <0 if the point is inside the solid virtual float GetDensity( float _x, float _y, float _z ) const override { Float3 P = Float3_Set( _x, _y, _z ); Float3 v = Float3_Subtract( P, m_origin ); float l = Float3_LengthSquared( v ); float d = Float_Sqrt(l) - m_radius; return d; } // estimates the gradient at the given point virtual Float3 GetNormal( float _x, float _y, float _z ) const override { Float3 P = Float3_Set( _x, _y, _z ); float d = this->AIsosurface::GetDensity( P ); float Nx = this->GetDensity( _x + 0.001f, _y, _z ) - d; float Ny = this->GetDensity( _x, _y + 0.001f, _z ) - d; float Nz = this->GetDensity( _x, _y, _z + 0.001f ) - d; Float3 N = Float3_Normalized( Float3_Set( Nx, Ny, Nz ) ); return N; } What is a nice and fast way to compute those values when the shape is bounded by a low number of half-spaces?

• What is the easiest and fastest way to display an SDL_Surface in a window with SDL2?

  - by Semmu

  I would like to have an SDL_Surface representing the contents of the window, just like in the old days with SDL1.2. What is the best and fastest way to do it in SDL2? What I found is that I need an SDL_Window, an SDL_Renderer for that window, an SDL_Texture to render, and an SDL_Surface to create a texture from. This seems a bit too much to me, since I just want to display a single image on the screen. Not to mention the impact on the performance. On my machine (Lenovo Y510p laptop) this whole procedure takes 9ms, without any memory allocation, only using pre-allocated variables and totally black SDL_Surface. Is there a way I could speed up things?

• Artificial Neural Networks

  - by user1724140

  I have an Artificial Networks which needs to recognize 130 different types of moves encoded in terms of 1s and 0s. Therefore the number of outputs I used is 8 so that all my patterns could be distinguished. However, by using 8 outputs, the different types of patterns possible is 256, leaving me with 126 different types of patterns useless. Do these extra 126 different patterns ruin my ANN's ability? Is there a better way not to have these unused holes?

• How to add two textures ,one is used as background and another one is used in a rotating cube!

  - by VampirEMufasa

  I am working in OpenGL ES 2.0. Now I am writing a demo for my project, I load two png images as my textures with the libSOIL But now I need to use one of them as the texture of my demo's background and another one as the texture of a rotating cube. In OpenGL ES 2.0, the adding texture operation is in the shader But now I don't know how to add the different textures to the different place in a shader Who can help me! Thank you very much!

• Camera not working

  - by user17548

  I made a camera in DX9. To move forward I press the Up arrow. To rotate on the Y axis I use the mouse. When I perform these movements on their own the camera moves at the speed I want. However, if I hold down Up and move the mouse at the same time then the camera moves a lot faster than it should. I want it to move at the same speed as it does when only the Up arrow is pressed. I think I need to normalize something somewhere but not sure what and not sure where. Have tried various combinations without success so if anyone can point me in the right direction that would be great. Thanks. My code #define KEY_DOWN(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0) LRESULT WINAPI MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam ) { if( KEY_DOWN(VK_UP)) MovePlayer(D3DXVECTOR3(0, 0, -1.0f)); if( KEY_DOWN(VK_DOWN)) MovePlayer(D3DXVECTOR3(0, 0, 1.0f)); switch( msg ) { case WM_MOUSEMOVE: ProcessMouseInput(); } } void MovePlayer( D3DXVECTOR3 in_vec ) { D3DXMATRIX CameraRot; D3DXMatrixRotationY(&CameraRot,D3DXToRadian(AngleY)); D3DXVECTOR3 CameraRotTarget; D3DXVec3TransformNormal(&CameraRotTarget,&in_vec,&CameraRot); CameraPos += (m_timeElapsed * CameraRotTarget); } void ProcessMouseInput() { GetCursorPos( &CurrentMouseState ); if ((CurrentMouseState.x != GameMouseState.x) || (CurrentMouseState.y != GameMouseState.y)) { int dx = CurrentMouseState.x - GameMouseState.x; int dy = CurrentMouseState.y - GameMouseState.y; AngleY+=m_timeElapsed*dx*7.0f; } GameMouseState = CurrentMouseState; // Set back to window center in Render function } VOID UpdateCamera() { D3DXVECTOR3 CameraOrigTarget(0, 0, -1); D3DXVECTOR3 CameraOrigUp(0, 1, 0); D3DXMATRIX CameraRot; D3DXMATRIX CameraRotX; D3DXMatrixRotationX(&CameraRotX,D3DXToRadian(AngleX)); D3DXMATRIX CameraRotY; D3DXMatrixRotationY(&CameraRotY,D3DXToRadian(AngleY)); CameraRot = CameraRotX * CameraRotY; D3DXVECTOR3 CameraRotTarget; D3DXVec3TransformNormal(&CameraRotTarget,&CameraOrigTarget,&CameraRot); D3DXVECTOR3 CameraTarget; CameraTarget = CameraPos + CameraRotTarget; D3DXVECTOR3 vUpVec( 0.0f, 1.0f, 0.0f ); D3DXMatrixLookAtLH( &matView, &CameraPos, &CameraTarget, &vUpVec ); g_pd3dDevice->SetTransform( D3DTS_VIEW, &matView ); D3DXMatrixPerspectiveFovLH( &matProj, D3DX_PI / 4, 1.0f, 1.0f, 100.0f ); g_pd3dDevice->SetTransform( D3DTS_PROJECTION, &matProj ); }

• How to visualize real time data on Android? [closed]

  - by matarsak

  I want to build and android app that visualizes real time data (2D animation). I set up a UDP channel that get the data, now I want to visualize it. I know that I can use OpenGL ES, but after a few weeks, I dont think that I'm able to learn that. What about Android Processing? Could it be used for an extensive visualization task like this? or is it limited in some way? I've heard it's not hard learn. Any other options?

• What does the Sys_PageIn() function do in Quake?

  - by Philip

  I've noticed in the initialization process of the original Quake the following function is called. volatile int sys_checksum; // **lots of code** void Sys_PageIn(void *ptr, int size) { byte *x; int j,m,n; //touch all memory to make sure its there. The 16-page skip is to //keep Win 95 from thinking we're trying to page ourselves in (we are //doing that, of course, but there's no reason we shouldn't) x = (byte *)ptr; for (n=0 ; n<4 ; n++) { for (m=0; m<(size - 16 * 0x1000) ; m += 4) { sys_checksum += *(int *)&x[m]; sys_checksum += *(int *)&x[m + 16 * 0x10000]; } } } I think I'm just not familiar enough with paging to understand this function. the void* ptr passed to the function is a recently malloc()'d piece of memory that is size bytes big. This is the whole function - j is an unreferenced variable. My best guess is that the volatile int sys_checksum is forcing the system to physically read all of the space that was just malloc()'d, perhaps to ensure that these spaces exist in virtual memory? Is this right? And why would someone do this? Is it for some antiquated Win95 reason?

• What is the proper way to use string::find to look for a word? [migrated]

  - by RubyKing

  How would I look through a string for a word rather then each character in that word. I have my code here and it always seems to find everything that is .obj even if its o or b or j or "." I checked the docuementation here but was unable to find an answer. Here is my code: string &str = *it; if(it->find(".obj")) { cout << "Found .Obj" << endl; } I also tried to use string::compare but that failed.

• libgdx - #iterator() cannot be used nested

  - by TimSim

  I'm getting this error when I try to check if any of the targets overlap each other: iterTargets = targets.iterator(); while (iterTargets.hasNext()) { Target target = iterTargets.next(); for (Target otherTarget:targets) { if (target.rectangle.overlaps(otherTarget.rectangle)) { // do something } } } So I can't do that? How am I supposed to check each member of an array to see if it overlaps any other member?

• How can I find the closest vector to another in a specific direction?

  - by Sniper

  Perhaps I am not phrasing it incorrectly in my searches, but I can not find anything on this. I have a vector3 with a specific direction that it is facing, I want to get the closest object to that position in that specific direction. Basically I want to get the object that is being aimed at. I have thought about finding all objects within a box and then finding the closest object to my vector from them results, but I am sure that there is a more efficient way. The Z axis is optional, the objects are most likely within a few meters of the search vector. http://i.stack.imgur.com/FafAu.jpg

• j2me sprite array

  - by danis

  I`ve tried to put the same Image into an array (array contains 22 Images) to form inventory. for(int i=0;i>22;i++){ invSprite[i] = new Sprite(ingame); invSprite[i].defineReferencePixel(0,0); } and if(inventory){ for(int i=0;i>22;i++){ if(i>=11){ invSprite[i].setRefPixelPosition(0+15*i, 27); }else{ invSprite[i].setRefPixelPosition(0+15*i, 42); } invSprite[i].paint(g); } } If the inventory is on it will show those Images but it`s not. PS if I would try invSprite[0].setRefPixelPosition(10, 27); invSprite[0].paint(g); it would throw an java/lang/NullPointerException

• How would I go about updating my electronic circuit simulator's 'electricity'?

  - by liqwidice

  I have made an application which allows the user to place down wires, power sources, and inverters on a virtual circuit board. All connections between tiles are automatic, as shown here: As you can see in the last image, the updating of power throughout this grid is not yet functioning. I think I understand how to do this updating conceptually, but getting it to work in my program is appearing to be much more difficult than I first imagined. My source code can be found here. If you have any tips as to how to I might approach this monstrous task, please let me know. EDIT The goal here is to simply get a working application. Getting tiles to pass on power to their neighbors is quite easy, but the tricky part is getting wires to "unpower" after the removal of a power source. The size of the grid is just 18x18, so efficiency really isn't a factor, for those wondering.

• Rotating a sprite to touch

  - by user1691659

  I know this has been asked before and Ive looked through peoples questions and answers all over the internet and I just cant get it to work. Im sure its down to my inexperience. Ive got an arrow attached to a sprite, this sprite appears when touched but I want the arrow to point where the sprite will launch. I have had the arrow moving but it was very erratic and not pointing as it should. Its not moving at the moment but this is what I have. - (void)update:(ccTime)delta { arrow.rotation = dialRotation; } -(void) ccTouchMoved:(UITouch*)touch withEvent:(UIEvent *)event { pt1 = [self convertTouchToNodeSpace:touch]; CGPoint firstVector = ccpSub(pt, arrow.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(pt1, arrow.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); dialRotation += currentTouch - previousTouch; } I have got pt from ccTouchBegan the same way as pt1 Thanks

• TileEntitySpecialRenderer only renders from certain angle

  - by Hullu2000

  I'm developing a Minecraft mod with Forge. I've added a tileentity and a custom renderer for it. The problem is: The block is only visible from sertain angles. I've compaed my code to other peoples code and it looks pretty much like them. The block is opaque and not to be rendered and the renderer is registered normally so the fault must be in the renderer. Here's the renderer code: public class TERender extends TileEntitySpecialRenderer { public void renderTileEntityAt(TileEntity tileEntity, double d, double d1, double d2, float f) { GL11.glPushMatrix(); GL11.glTranslatef((float)d, (float)d1, (float)d2); HeatConductTileEntity TE = (HeatConductTileEntity)tileEntity; renderBlock(TE, tileEntity.getWorldObj(), tileEntity.xCoord, tileEntity.yCoord, tileEntity.zCoord, mod.EMHeatConductor); GL11.glPopMatrix(); } public void renderBlock(HeatConductTileEntity tl, World world, int i, int j, int k, Block block) { Tessellator tessellator = Tessellator.instance; GL11.glColor3f(1, 1, 1); tessellator.startDrawingQuads(); tessellator.addVertex(0, 0, 0); tessellator.addVertex(1, 0, 0); tessellator.addVertex(1, 1, 0); tessellator.addVertex(0, 1, 0); tessellator.draw(); } }

• How do you make a 2D character in Javascript? [on hold]

  - by user36507

  How do you actually make a character in JS? I know you are supposed to use objects like var character = new Object(); (If the code has errors I apologise.)But how do you make the character move using keys WASD or let the character pick up items. What I want to know is that whether you need a canvas created specially for the character, how to add attributes and use keys to move it all in code. Also it would be great if you could help me on how to import pictures to JS to use it.

• What arguments do I send a function being called by a button in python?

  - by Jared

  I have a UI, in that UI is 4 text fields and 1 int field, then I have a function that calls to another function based on what's inside of the text fields, this function has (self, *args). My function that is being called to takes five arguments and I don't know what to put in it to make it actually work with my UI because python button's send an argument of their own. I have tried self and *args, but it doesn't work. Here is my code, didn't include most of the UI code since it is self explanatory: def crBC(self, IKJoint, FKJoint, bindJoint, xQuan, switch): ''' You should have a controller with an attribute 'ikFkBlend' - The name can be changed after the script executes.

• MySQL my.cnf file not being read, Ubuntu 10.04 64bit

  - by reallyordinary

  I've been researching this for a few hours with no luck. Basically it looks like my server's my.cnf file isn't being read at all. I've searched my server, and there's only one my.cnf file on it, located at /etc/mysql/my.cnf. Its ownership is root:root. I'm running Ubuntu 10.04 64bit on a Linode.com server. I have the latest versions of MySQL and PHP installed. I've edited the my.cnf file, commented out "skip-innodb", and have set innodb to be the default storage engine using default-storage-engine = innodb And then restarted mysql. But when I do show engines, MyISAM is still coming up as the default engine. Also - none of the innodb settings I've added to the my.cnf file are being read. For example, I have this in my.cnf: innodb_buffer_pool_size=4G But in phpmyadmin, InnoDB is showing as having a buffer pool size of 8,192 KiB. Similarly, I have this in the my.cnf: innodb_data-file_path = ibdata1:500M:autoextend But in phpmyadmin, it's reading as ibdata1:10M:autoextend. It doesn't look like MyISAM info is being read from the my.cnf file either. The my.cnf file has skip-external-locking queried out, but it's showing as "on" in phpmyadmin. So - yeah, it looks like nothing in the my.cnf file is being read at all. But the server still works. I'm running a Drupal site on it and it seems to operate fine. So mysql seems to be drawing default settings from... some mysterious secret location. Any idea how I can make mysql see and use this my.cnf file? Actually, wait - it looks like it may be being read, not sure. I checked the error.log and found this: 101128 4:28:52 [ERROR] Cannot find or open table databasename/cache_apachesolr from the internal data dictionary of InnoDB though the .frm file for the table exists. Maybe you have deleted and recreated InnoDB data files but have forgotten to delete the corresponding .frm files of InnoDB tables, or you have moved .frm files to another database? or, the table contains indexes that this version of the engine doesn't support. See http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting.html how you can resolve the problem. InnoDB: Error: auto-extending data file ./ibdata1 is of a different size InnoDB: 640 pages (rounded down to MB) than specified in the .cnf file: InnoDB: initial 32000 pages, max 0 (relevant if non-zero) pages! InnoDB: Could not open or create data files. InnoDB: If you tried to add new data files, and it failed here, InnoDB: you should now edit innodb_data_file_path in my.cnf back InnoDB: to what it was, and remove the new ibdata files InnoDB created InnoDB: in this failed attempt. InnoDB only wrote those files full of InnoDB: zeros, but did not yet use them in any way. But be careful: do not InnoDB: remove old data files which contain your precious data! 101128 4:28:52 [ERROR] Plugin 'InnoDB' init function returned error. 101128 4:28:52 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 101128 4:28:52 [ERROR] /usr/sbin/mysqld: unknown variable 'innodb_lock_wait_timout=50' 101128 4:28:52 [ERROR] Aborting 101128 4:28:52 [Note] /usr/sbin/mysqld: Shutdown complete

• BSOD Code 16, artifacts all over the place (gtx 260)

  - by belinea

  I have a following, quite dated rig E8400 Core 2 Duo cpu Intel Dragontail Peak DP35DP motherboard on Intel Bearlake P35 chipset 4GB ram Geforce 260gtx Corsair 650W PSU Windows 7 64 bit The following things has happened in the last few days. I first decided to update my Nvidia drivers to the latest version. That was 4 days ago. PC worked fine for 2 days and I was able to play few games as well without any problems. Then 2 days ago a first crash happened while playing the new XCOM game. BSOD code 16. Just the blue screen, no artifacts. PC rebooted and worked well again, I continued playing this game for another 2 hours and went to sleep. Next evening I tried to play some BF3 multiplayer (use to play on LOW settings). Approx. 10 minutes into the game red/pink-ish artifacts appeared on the screen and game quit to desktop. Restarted the game and another 3-4 minutes afterwards another crash to desktop but this time followed shortly by BSOD Code 16. From that moment I started to seeing artifacts on random startups, including Windows loading screen and the BIOS itself. Windows would still load but soon enough it would BSOD on a simple task like opening a Internet browser. Today I get tons of artifacts (little small red dashes all over the screen) on BIOS, loading screen, normal Windows mode as well as safe mode. I suspect it wouldn't be drivers but I tried removing and sweeping them entirely in the safe mode. PC would still start with artifacts all over the place but would load the normal mode, just without the driver, in the default lowest resolution. As soon as proper Nvidia drivers are installed though and PC rebooted, Windows doesn't load at all as BSOD now appears on loading screen. However, again, if I go to safe mode and remove drivers, normal mode launches fine. So obviously crash happens only on high resolution. I opened my machine this morning and gave it a proper cleaning even though it wasn't heavily dusted. It didn't help and number of artifacts seems to increase with every PC restart. I write these words in safe mode, which works, but I have to look through all the red dots and dashes. I don't have built in GPU chipset so I can't try removing my Geforce card nor can I borrow A GPU from anyone else. What are my options? I was looking into getting a completely new rig around Christmas so I'm not freaking out about this. If everything points to hardware issue I may simply decide to get the new machine earlier and don't bother with fixing this one. However it would be great to learn more if this is indeed situation that has slim chances of getting sorted. I realize BSOD Code 16 is rather popular topic online but every story seems a bit different and there can be number of issues with it. Hence a new thread.

• How do I fix my resolution after Directx install through Steam?

  - by Justin

  I'm a bit long-winded so see bottom for quick version and specs. Friendly Hello: Hello all on these askUbuntu pages, I just recently built my own computer and decided to switch to Ubuntu for the extra coolness. I've been learning a lot through all this, and mostly been trying to figure out issues on my own (read: Google searches). However, I couldn't seem to find others with this problem so I've come here for help. Detailed Recount: So I just used WINE and WINETRICKS to install Steam. All went well and it worked. Then I went to trying a game out. I remembered that Orcs Must Die! worked from http://www.steamgamesonlinux.com/ so I tried that out. After selecting to download it, that's when the problem occurred. The screen suddenly zoomed in!!! I think it's the resolution right? Half the screen is cut off and I can't see parts of the right side of windows. My theory is that this is due to Direct X being installed through Steam, as Steam automatically installed it as I chose to download the game. It didn't even ask me to install Direct X or not ): It all happened so fast. This all being said, the game works fine! It looks a little strange, as if the resolution was off, but it plays just fine. What I did so far: Restarted my computer. Didn't work -_- Researched Steam installing DirectX on Ubuntu then messing up resolution and couldn't really find anything. Researched uninstalling DirectX from Ubuntu but only found uninstalling DirectX after having been installed with Wine, not through Steam. Got mad and ate my feelings. Tried "xrandr -s 0" but it didn't do anything. Ran xrandr alone and terminal showed this: Screen 0: minimum 8 x 8, current 640 x 480, maximum 16384 x 16384 DVI-I-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 640x480 59.9*+ 320x240 120.1 DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) DP-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) About now I was mad so I played Odin's Sphere then took a nap. Back to it! I entered the following: xrandr --output DVI-I-0 --mode 1024x768 But I was met with this message: xrandr: cannot find mode 1024x768 I get the same messages for 800x600, 1400x1050, and seemingly any other combination of numbers. I then tried Going into System Settings then Displays, then playing around in there. My Resolution is set to 640x480 and there are no other options for me to choose from. Rotation has Normal, Clockwise, Counter Clockwise, and 180 Degrees. It's set to Normal and I haven't messed with that. Launcher Placement has Unknown and All Displays as its two options. It's set to Unknown, but moving it to All Displays doesn't seem to do anything. Finally, when I click Detect Displays, nothing seems to happen. Quick Version: Linux noob. Steam installed with Wine and Winetricks. Steam downloaded and installed game + DirectX. Resolution messed up now (I think; pretty sure), can't fix it, very annoying, no idea what's going on, halp! Specs: Ubuntu Version 12.04 Wine Version 1.4.1 Have not changed any settings in Wine Using Winetricks Graphics Card: http://www.gigabyte.com/products/pro...px?pid=4361#sp Drivers: Proprietary (Installing those were a LOT of fun) Also let it be known that I have a DVI to VGA cord running from my Graphics card to my monitor. If any more information is needed I am ready to report. Thank You: Thanks a lot for your help and all the work you do to support noob ubuntuers like me (:
