  • Delay keyboard input help

    - by Stradigos
    I'm so close! I'm using the XNA Game State Management example found here and trying to modify how it handles input so I can delay the key/create an input buffer. In GameplayScreen.cs I've declared a double called elapsedTime and set it equal to 0. In the HandleInput method I've changed the Key.Right button press to: if (keyboardState.IsKeyDown(Keys.Left)) movement.X -= 50; if (keyboardState.IsKeyDown(Keys.Right)) { elapsedTime -= gameTime.ElapsedGameTime.TotalMilliseconds; if (elapsedTime <= 0) { movement.X += 50; elapsedTime = 10; } } else { elapsedTime = 0; } The pseudo code: If the right arrow key is not pressed set elapsedTime to 0. If it is pressed, the elapsedTime equals itself minus the milliseconds since the last frame. If the difference then equals 0 or less, move the object 50, and then set the elapsedTime to 10 (the delay). If the key is being held down elapsedTime should never be set to 0 via the else. Instead, after elapsedTime is set to 10 after a successful check, the elapsedTime should get lower and lower because it's being subtracted by the TotalMilliseconds. When that reaches 0, it successfully passes the check again and moves the object once more. The problem is, it moves the object once per press but doesn't work if you hold it down. Can anyone offer any sort of tip/example/bit of knowledge towards this? Thanks in advance, it's been driving me nuts. In theory I thought this would for sure work. CLARIFICATION Think of a grid when your thinking about how I want the block to move. Instead of just fluidly moving across the screen, it's moving by it's width (sorta jumping) to the next position. If I hold down the key, it races across the screen. I want to slow this whole process down so that holding the key creates an X millisecond delay between it 'jumping'/moving by it's width. EDIT: Turns out gameTime.ElapsedGameTime.TotalMilliseconds is returning 0... all of the time. I have no idea why.

  • iPhone - Reset UINavigation Controller

    - by Ward
    Hey there, I have a UINavigationController inside a UITabBarController. When a user presses the first tab, I want to reset the navigation controller back to the first screen instead of displaying whichever view they last selected in the navigation controller. Is there an easy way to reset the stack? Thanks, Howie

  • How to output formatted HTML from PHP?

    - by Tim
    I like to format all my HTML with tabs for neatness and readability. Recently I started using PHP and now I have a lot of HTML output that comes from in between PHP tags. Those output lines all line up one the left side of the screen. I have to use /n to make a line go to the next. Is there anything like that for forcing tabs, or any way to have neat HTML output coming from PHP?

  • Cursor backed ExpandableListView data update

    - by Aleksander O
    Hi I'm implementing CRUD functionality using ExpandableListView. Wen I delete a parent data on screen refreshes automatically but it doesn't when I delete a child. I've solved this with: int categoryId = ExpandableListView.getPackedPositionGroup(info.packedPosition); getExpandableListView().collapseGroup(categoryId); getExpandableListView().expandGroup(categoryId); Is there any better way to this? Thanks Aleksander

  • Intersection of Inner Polygons of MKPolygon being colored - iOS

    - by Josh Glick
    I am trying to create a fog of war style map where areas I have visited are uncovered and the rest of the map is "hidden". I am using a MKPolygonOverlay that covers the whole map and create inner polygons around all the locations I have visited. However in areas where these inner polygons overlap, that portion of the overlay is still being drawn. As a new user I can't post pictures but here is a link to the image: http://dl.dropbox.com/u/13815916/Screen%20Shot%202012-06-29%20at%204.40.20%20AM.png

  • MySQL-problem when baking with CakePHP.

    - by timkl
    I am currently reading "Beginning CakePHP:From Novice to Professional" by David Golding. At one point I have to use the CLI-command "cake bake", I get the welcome-screen but when I try to bake e.g. a Controller I get the following error messages: Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117 Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122 Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130 Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables. I suspect that the error-messages has to do with php trying to access the wrong mysql-socket, namely the default osx mysql-socket - instead of the one that MAMP uses. Hence I change my database configurations to connect to the UNIX mysql-socket (:/Applications/MAMP/tmp/mysql/mysql.sock): class DATABASE_CONFIG { var $default = array( 'driver' => 'mysql', 'connect' => 'mysql_connect', 'persistent' => false, 'host' =>':/Applications/MAMP/tmp/mysql/mysql.sock', // UNIX MySQL-socket 'login' => 'my_user', 'password' => 'my_pass', 'database' => 'blog', 'prefix' => '', ); } But I get the same error-messages with the new socket: Warning: mysql_connect(): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock:3306' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117 Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122 Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130 Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables. Also, even though I use the UNIX-socket that MAMP show on it's welcome-screen, CakePHP loses the database-connection, when using this socket instead of localhost. Any ideas on how I can get bake to work?

  • Framework for iPhone wait screens

    - by 4thSpace
    I ran across a small framework some time back that someone put together for iPhone wait screens. But now I can't find any trace of it. Does anyone have a link to it? It may not be a framework as much as a few code snippets. But the guy had it all pre-made. You just needed to implement and specify the type of wait screen you wanted.

  • MVC4 dynamically changing master layout page doesn't work on first load

    - by Kelvin
    I have an MVC4 mobile project that I want to add a desktop (non mobile) page to for some users. I have added a new desktop master page and assigned my view to use it. The first time I navigate to the page it renders using jquerymobile which appears to somehow be cached from the previous screen. If I hit F5 to refresh the page it displays using the assigned desktop masterpage correctly. Can anyone tell me how to fix this? Any insight appreciated

  • Ajax problem not displaying data using multiple javascript calls...

    - by Ronedog
    I'm writing an app that uses ajax to retrieve data from a mysql db using php. Because of the nature of the app, the user clicks an href link that has an "onclick" event used to call the javascript/ajax. I'm retrieving the data from mysql, then calling a separate php function which creates a small html table with the necessary data in it. The new table gets passed back to the responseText and is displayed inside a div tag. The tables only have around 10-20 rows of data in them. This functionality is working fine and displays the data in html form exactly as it needs to be on the page. The problem is this. the HREF "onclick" event needs to run multiple scripts one right after the other. The first script updates the "existing" data and inside the "update_existing" function is a call to refresh a section of the page with the updated HTML from the responseText. Then when that is done a "display_html" function is called which also updates a different section of the page with it's newly created HTML table. The event looks like this: Update This string gets built dynamically using php with parameters supplied, but for this example I simply took the parameters out so it didn't get confusing. The "update_existion() function actually calls the display_html() function which updates a section of the page as needed. I need to update a different section of the page on the same click of the mouse right after the update, which is why I'm calling the display_html() again, right after it. The problem is only the last call is being updated on my screen. In other words, the 2nd function call "display_html()" executes and displays the refreshed data just fine, but the previous call to update_existing() runs and updates the database properly, but doesn't display on the screen unless I press the browsers "refresh" button, which of course displays the new data exactly how I want it to, but I don't want the users to have to press the "refresh" button. I tried adding multiple "display_html() calls one right after the other, separating all of them with the semicolon and learned that only the very last function call actually refreshed the div element on the html page with the table information, although all the previous display_html() calls worked, they couldn't be seen on the page without a refresh of the browser. Is this a problem with javascript, or the ajax call, or is this a limitation in the DOM that only allows one element to be updated at a time. The ajax call is asynchroneous, but I've tried both, only async works period. This is the same in both Firefox and Internet Explorer Any ideas what's going on and how to get around it so I can run these multiple scripts?

  • See images in SSMS?

    - by Vaccano
    I was browsing around and found this blog post: http://erikej.blogspot.com/2010/04/version-3-of-exportsqlce-now-available.html (It is for a great add in if you user SQL Server CE.) On that post I saw an screen shot of SSMS with images in the results. How is this done? I have images in my database (PNG files that are serialized via memory stream), but I just see numbers when I select the image column.

    I'm having some problems with users cheating my online game by using macros to automatically click certain spots on the screen in a certain order to automate various tasks without having to actually be playing the game. Are there any methods that can be used to block this kind of activity without having to plaster CAPTCHAs all over the site and ruin the experience for the honest users?

  • Always center UIView

    - by bresc
    Hi, I have a small UIView that should appear always in the center of the screen. This works great for portrait mode but does not in landscape. To draw the UIView I use: myView.frame = CGRectMake((visibleArea.size.width - MY_VIEW_WIDTH) / 2, (visibleArea.size.height - MY_VIEW_HEIGHT) / 2, MY_VIEW_WIDTH, MY_VIEW_HEIGHT); myView.autoresizingMask = ( UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin ); Any ideas what might be missing?
