  • Show and Fade UIImageView after 2 Seconds

    - by user1536432
    I am working on a notification system in my iPhone game and want an image to pop up on the screen and automatically fade after 2 seconds. User clicks a button that calls the method "popupImage" An image appears on the screen in a designated spot, it doesn't need to fade in The image fades out by itself after being on the screen for 2 seconds. Is there any way of doing this? Thanks ahead of time.

  • How to implement tail calls in a custom VM

    - by DeadMG
    How can I implement tail calls in a custom virtual machine? I know that I need to pop off the original function's local stack, then it's arguments, then push on the new arguments. But, if I pop off the function's local stack, how am I supposed to push on the new arguments? They've just been popped off the stack.

  • Java Swing UI Changing Method

    - by vigilant
    I would like to use Swing to program a simple learning game. I am wondering what would be best way to switch between UI screens. For example, I would have a screen for the Main Menu, and then when the user presses a button on that screen, I would swap out the whole screen for a completely different one. Then, arbitrary screens can be swapped in at any moment, and all of their event handlers would be reactivated while the inactive screen's event handlers will be deactivated. What type of Swing component/control would I use for each of the 'screens'. Is this even doable?

  • How to show a live Presentation from an Android phone?

    - by Pentium10
    This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

  • How do I get my Windows Forms application to use a custom main function and get access to the Applic

    - by burble
    Hi Folks I am trying to use a Main () function in a class to control the program flow in my vb .net Windows Forms application. I have added a splash screen component and a login screen, and customised my main sdi form. I have set the startup form to be my main function in the Application Page of the Project Designer, and everything seems to work fine(ish). However, I would like to use: Me.MinimumSplashScreenDisplayTime = 5000 to ensure that the splash screen is visible, but it is not recognised by the system unless I tick the Enable Application Framework check box on the Project Designer. If I do this, on startup the program ignores the login and splash screens and all my customisation and just displays a default Form1, even though I have also specified my splash screen in the AF dropdown list. Of course, there are alternative ways to delay a splash screen, such as putting the thread temporarily to sleep (which didn't seem to work), but I suspect that there are other things in the AF that I may want to use. Any suggestions on how I can get round this please, and get a sensible means of controlling program flow? Any thoughts on the best overall structure for organising program flow would also be helpful too. I am concerned both about going down a Microsoft or an alternative custom route that may cause me problems later, as the application becomes more complex. Thankses.

  • How to show a firemonkey form on second monitor

    I am trying to display a FireMonkey form on a second monitor, using C++Builder with following code: void __fastcall ShowFormOnScreen( int OutMon ) { MyForm->Top = 0; MyForm->BorderStyle = bsNone; MyForm->WindowState = wsNormal; MyForm->Left = Screen->Monitors[OutMon]->Left; MyForm->Height = Screen->Monitors[OutMon]->Height; MyForm->Width = Screen->Monitors[OutMon]->Width; MyForm->Show(); } Unfortunately, the Screen object does not have the Monitors property, so how can do this in FireMonkey?

  • IOS center bottom position view

    - by Ben_hawk
    I do the following to a loading animation, to place it at the bottom center of the screen. CGPoint bottomCenter = CGPointMake((self.imageView.bounds.size.width / 2), (self.imageView.bounds.size.height * 0.8)); self.activityView.center = bottomCenter; (imageView is the full screen splash image) If the orientation is portrait, it is positioned perfectly, however turning on its side, in landscape or upside down portrait and the animation ends up miles away :S Does anyone know the correct way to position this loading animation, its for the splash screen.

  • Is Android (read typical devices) fast enough for a game that requires plotting pixel by pixel rather than blitting

    - by mP
    i have an idea for an Android game which is a little different from the typical game that usually moves sprites(bitmaps) around the screen. Id want to plot lots of little pixels to create my visuals. PROS no bitmaps required pixel plotting of stuff like "fire" can react to wind. no need to scale bitmaps, works w/ any screen res (lets pretend device can handle more drawing because its got a bigger screen). CONS slower to plot pixels than blit bitmaps need lot of animation frames. WISHES id like to update my game in real time, more is better 30fps is good but not essential, 15fps is enough. PERFORMANCE Q... Is the typical Android device fast enough to plot say half a screenful of pixels w/ a default background ? if full screen is not practical what window size should be able to handle such refreshes

  • stdio data from write not making it into a file

    - by user1551209
    I'm having a problem with using stdio commands for manipulating data in a file. I short, when I write data into a file, write returns an int indicating that it was successful, but when I read it back out I only get the old data. Here's a stripped down version of the code: fd = open(filename,O_RDWR|O_APPEND); struct dE *cDE = malloc(sizeof(struct dE)); //Read present data printf("\nreading values at %d\n",off); printf("SeekStatus <%d>\n",lseek(fd,off,SEEK_SET)); printf("ReadStatus <%d>\n",read(fd,cDE,deSize)); printf("current Key/Data <%d/%s>\n",cDE->key,cDE->data); printf("\nwriting new values\n"); //Change the values locally cDE->key = //something new cDE->data = //something new //Write them back printf("SeekStatus <%d>\n",lseek(fd,off,SEEK_SET)); printf("WriteStatus <%d>\n",write(fd,cDE,deSize)); //Re-read to make sure that it got written back printf("\nre-reading values at %d\n",off); printf("SeekStatus <%d>\n",lseek(fd,off,SEEK_SET)); printf("ReadStatus <%d>\n",read(fd,cDE,deSize)); printf("current Key/Data <%d/%s>\n",cDE->key,cDE->data); Furthermore, here's the dE struct in case you're wondering: struct dE { int key; char data[DataSize]; }; This prints: reading values at 1072 SeekStatus <1072> ReadStatus <32> current Key/Data <27/old> writing new values SeekStatus <1072> WriteStatus <32> re-reading values at 1072 SeekStatus <1072> ReadStatus <32> current Key/Data <27/old>

  • Structuring iPhone/iPad application views

    - by Mark
    I have an idea about an application that I want to build and Im new to iPhone/iPad development (but not new to development in other languages/frameworks such as .NET and Java). I want to layout some views on the screen so that they animate (slide in) from different directions into their places. The question is about the strucuture of the application, if I have say 4 rectanglular areas on the screen that contain business data, such as contacts (name, photo, etc...) and they all take up different widths of the screen (say the first contact takes up one row of the screen, but the next 2 take up half the width of the next row each, and so on). Should I create a custom view for the different sized contact views, (i.e. LargeCustomView and SmallCustomView, and any other special type that I make) or should it all be one type, say, CustomerDetailsView which could be stretched to fit at design time? Also, if there were, say, 3 different instances of the same custom view on the one screen, are there 3 instances of the view controller also? Im a little confused about powering the data behind a view, can someone shed some light on this for me? Do I just set the properties (say an instance variable ContactForView) on the view controller for each instance? Thanks for any help you can give Cheers, Mark

  • Calculating the angle between two points

    - by kingrichard2005
    I'm currently developing a simple 2D game for Android. I have a stationary object that's situated in the center of the screen and I'm trying to get that object to rotate and point to the area on the screen that the user touches. I have the constant coordinates that represent the center of the screen and I can get the coordinates of the point that the user taps on. I'm using the formula outlined in this forum: How to get angle between two points? -It says as follows "If you want the the angle between the line defined by these two points and the horizontal axis: double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;". -I implemented this, but I think the fact the I'm working in screen coordinates is causing a miscalculation, since the Y-coordinate is reversed. I'm not sure if this is the right way to go about it, any other thoughts or suggestions are appreciated.

  • Pygame single push event

    - by Miller92Time
    in Pygame i am trying to translate an image by 10% in each direction using each arrow key. right now the code i am using moves the image as long as the key is pushed down, what I want is for it to move only once regardless if the key is still pushed down or not. if event.type == KEYDOWN: if (event.key == K_RIGHT): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_x(100) draw(1) if (event.key == K_LEFT): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_x(-100) draw(2) if (event.key == K_UP): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_y(100) draw(3) if (event.key == K_DOWN): DISPLAYSURF.fill((255,255,255)) #Clears the screen translation_y(-100) draw(4) is there a simpler way of implementing this besides using time.sleep

  • Problem running apps fullscreen in emulator

    - by Haakon
    I've created a device targeting 2.1 and having a screen screen size of 480x800 (WVGA). Some apps, including the one I'm currently writing, as well as the ApiDemos example, won't run fullscreen. I've uploaded a screenshot here: http://img248.imageshack.us/img248/503/emulator.png What could cause something like this? If I run these apps on my HTC Desire (which has the same resolution), they utilize the whole screen like they should.

  • buttons and menu items in cocos2d/objective-c

    - by peter61
    In my app, I'd like a method called whenever the user taps the screen (anywhere on the screen). Normally, I'd make a transparent UIButton that covers the whole screen. If I'm using the cocos2d framework, what's the best way to do this? Is it good practice to still use UIButtons? I've been reading about MenuItems but haven't found an easy way to make one giant fully transparent menu item? Thanks.

  • ASP.NET - Google Chrome caching DropDownList selections

    - by Fake
    I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database. It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem. Lets say the first dropdown list has the values of: VALUE1 VALUE2 VALUE3 And the second dropdown list has the values of: DUMBO1 DUMBO2 DUMBO3 I add an item to my cart. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I hit Checkout. Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) I hit the back button. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB) MOMENTARILY Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 Hit Checkout. Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) Go back. Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out. It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button. I am open to any solutions or suggestions at this point. Thanks!
