  • Moving x,y position of all array objects every frame in actionscript 3?

    - by Dylan Gallardo
    I have my code setup so that I have an movieclip in my library a class called "block" being duplicated multiple times and added into an array like this: function makeblock(e:Event){ newblock=new block; newblock.x=10; newblock.y=10; addChild(newblock); myarray[counter] = newblock; //adds a newblock object into array counter += 1; } Then I have a loop with a currently primitive way of handling my problem: stage.addEventListener(Event.ENTER_FRAME, gameloop); function gameloop(evt:Event):void { if (moveright==true){ myarray[0].x += 5; myarray[1].x += 5; myarray[2].x += 5 -(and so on)- My question is how can I change x,y values every frame for new objects duplicated into the array, along with the previous ones that were added. Of course with a more elegant way than writing it out myself... array[0].x += 5, array[1], array[2], array[3] etc. Ideally I would like this to go up to 500 or more array objects for one array so obviously I don't want to be writing it out individually haha, I also need it to be consistent with performance so using a for loop or something to loop through the whole array and move each x += 5 wouldn't work would it? Anyway, if anyone has any ideas that'd be great!

  • PHP while(variable=mysql_fetch_assoc) - explanation

    - by Petr
    Hi, I have been working with C# so this is quite strange for me: while($variable=mysql_fetch_assoc) I have not been able to look up in PHP manual how it works. I guess that in each loop it advances to next element of assoc.array. But what is this generally called in PHP? I am just not used to see '=' in loop condition.

    Hey all, why is this code throwing an out of memory error, when there is only 1 row in the database.. $request_db = mysql_query("SELECT * FROM requests WHERE haveplayed='0'") or die(mysql_error()); $request = mysql_fetch_array( $request_db ); echo "<table border=\"1\" align=\"center\">"; while ( $request['haveplayed'] == "0" ) { echo "<tr><td>"; echo $request['SongName']; echo "</td><td>"; echo "<tr><td>"; echo $request['Artist']; echo "</td><td>"; echo "<tr><td>"; echo $request['DedicatedTo']; echo "</td><td>"; } echo "</table>"; Thanks.

  • Loop crashing program having to do with 2D arrays

    - by user450062
    I am creating an encoding program and when I instruct the program to create a 5X5 grid based on the alphabet while skipping over letters that match up to certain pre-defined variables(which are given values by user input during runtime). I have a loop that instructs the loop to keep running until the values that access the array are out of bounds, the loop seems to cause the problem. This code is standardized so there shouldn't be much trouble compiling it in another compiler. Also would it be better to seperate my program into functions? here is the code: #include<iostream> #include<fstream> #include<cstdlib> #include<string> #include<limits> using namespace std; int main(){ while (!cin.fail()) { char type[81]; char filename[20]; char key [5]; char f[2] = "q"; char g[2] = "q"; char h[2] = "q"; char i[2] = "q"; char j[2] = "q"; char k[2] = "q"; char l[2] = "q"; int a = 1; int b = 1; int c = 1; int d = 1; int e = 1; string cipherarraytemplate[5][5]= { {"a","b","c","d","e"}, {"f","g","h","i","j"}, {"k","l","m","n","o"}, {"p","r","s","t","u"}, {"v","w","x","y","z"} }; string cipherarray[5][5]= { {"a","b","c","d","e"}, {"f","g","h","i","j"}, {"k","l","m","n","o"}, {"p","r","s","t","u"}, {"v","w","x","y","z"} }; cout<<"Enter the name of a file you want to create.\n"; cin>>filename; ofstream outFile; outFile.open(filename); outFile<<fixed; outFile.precision(2); outFile.setf(ios_base::showpoint); cin.ignore(std::numeric_limits<int>::max(),'\n'); cout<<"enter your codeword(codeword can have no repeating letters)\n"; cin>>key; while (key[a] != '\0' ){ while(b < 6){ cipherarray[b][c] = key[a]; if ( f == "q" ) { cipherarray[b][c] = f; } if ( f != "q" && g == "q" ) { cipherarray[b][c] = g; } if ( g != "q" && h == "q" ) { cipherarray[b][c] = h; } if ( h != "q" && i == "q" ) { cipherarray[b][c] = i; } if ( i != "q" && j == "q" ) { cipherarray[b][c] = j; } if ( j != "q" && k == "q" ) { cipherarray[b][c] = k; } if ( k != "q" && l == "q" ) { cipherarray[b][c] = l; } a++; b++; } c++; b = 1; } while (c < 6 || b < 6){ if (cipherarraytemplate[d][e] == f || cipherarraytemplate[d][e] == g || cipherarraytemplate[d][e] == h || cipherarraytemplate[d][e] == i || cipherarraytemplate[d][e] == j || cipherarraytemplate[d][e] == k || cipherarraytemplate[d][e] == l){ d++; } else { cipherarray[b][c] = cipherarraytemplate[d][e]; d++; b++; } if (d == 6){ d = 1; e++; } if (b == 6){ c++; b = 1; } } cout<<"now enter some text."<<endl<<"To end this program press Crtl-Z\n"; while(!cin.fail()){ cin.getline(type,81); outFile<<type<<endl; } outFile.close(); } } I know there is going to be some mid-forties guy out there who is going to stumble on to this post, he's have been programming for 20-some years and he's going to look at my code and say: "what is this guy doing".

  • form_for called in a loop overloads IDs and associates fields and labels incorrectly

    - by Katy Levinson
    Rails likes giving all of my fields the same IDs when they are generated in a loop, and this causes trouble. <% current_user.subscriptions.each do |s| %> <div class="subscription_listing"> <%= link_to_function s.product.name, "toggle_delay(this)"%> in <%= s.calc_time_to_next_arrival %> days. <div class="modify_subscription"> <%= form_for s, :url => change_subscription_path(s) do |f| %> <%= label_tag(:q, "Days to delay:") %> <%= text_field_tag(:query) %> <%= check_box_tag(:always) %> <%= label_tag(:always, "Apply delay to all future orders") %> <%= submit_tag("Change") %> <% end %> <%= link_to 'Destroy', s, :confirm => 'Are you sure?', :method => :delete %> </div> </div> <% end %> Produces <div class="subscription_listing"> <a href="#" onclick="toggle_delay(this); return false;">Pasta</a> in 57 days. <div class="modify_subscription"> <form accept-charset="UTF-8" action="/subscriptions/7/change" class="edit_subscription" id="edit_subscription_7" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="s5LJffuzmbEMkSrez8b3KLVmDWN/PGmDryXhp25+qc4=" /></div> <label for="q">Days to delay:</label> <input id="query" name="query" type="text" /> <input id="always" name="always" type="checkbox" value="1" /> <label for="always">Apply delay to all future orders</label> <input name="commit" type="submit" value="Change" /> </form> <a href="/subscriptions/7" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a> </div> </div> <div class="subscription_listing"> <a href="#" onclick="toggle_delay(this); return false;">Gummy Bears</a> in 57 days. <div class="modify_subscription"> <form accept-charset="UTF-8" action="/subscriptions/8/change" class="edit_subscription" id="edit_subscription_8" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="s5LJffuzmbEMkSrez8b3KLVmDWN/PGmDryXhp25+qc4=" /></div> <label for="q">Days to delay:</label> <input id="query" name="query" type="text" /> <input id="always" name="always" type="checkbox" value="1" /> <label for="always">Apply delay to all future orders</label> <input name="commit" type="submit" value="Change" /> </form> <a href="/subscriptions/8" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a> </div> </div> And that's a problem because now no matter which "Apply delay to all future orders" I select it always very helpfully checks the first box for me. How can I override the ID without doing something ugly and un-rails-like?

  • Refactoring a nested loop

    - by user3517441
    I have the following code which I use a lot of times in the class. for (int i = 0; i < someList.size(); i++) { for (int j = 0; j < someList.size(); j++) { if (i != j) { someList.get(i).sendMessageTo(someList.get(j))); //variable action } } } The purpose of the loop is to make each element in the List to send a message (or perform another action) to every element in the list except itself. Is there any way I can create a helper method so I don't have to repeat the loop code. I want to be able to state the variable action and call the helper method. Thanks.

  • PHP while loop, table row

    - by Elliott
    Hi, I'm trying to loop through a database and output data into a div, if there are 3 divs horizontally accross it will the start a new tr until it reaches another 3 etc. It is currently outputted like : [] [] [] [] [] [] Currently I have it working when it reaches 3 it starts a new row, but I don't know how I can only echo a new tr once? As it creates a new table row each time. echo '<table><tr>'; while ($result) { $i ++; if ($i&3) { echo '<td> <div>Row Data</div> </td>'; } else { echo '<tr> <td> <div>Row Data</div> </td></tr>'; } } echo '</tr></table>'; The $result variable is the recordset from my sql query, everything works fine I just don't know how to only create a new table row once? Thanks

  • VB.NET 2008 Application crashing during Do Loop

    - by RedHaze
    I am writing an application to compare each item on listbox1 to all items on listbox2. If the item is found, then remove it from both lists. The goal is to only have the items that were not found remain on both lists. The problem is, the application just hangs and I never get any results. I looked at my code several times and I cannot figure out what's going on (programming noob I know...). Can anybody help me with this? Code Snippet: Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim a As String Dim b As String Dim y As String For i As Integer = 0 To ListBox1.Items.Count - 1 a = ListBox1.Items(i) y = 1 Do While y = 1 For x As Integer = 0 To ListBox2.Items.Count - 1 b = ListBox2.Items(x) Dim res As Int16 = String.Compare(a, b) If res = 0 Then y = 0 ListBox2.Items.Remove(i) ListBox2.Items.Remove(x) ElseIf x = ListBox1.Items.Count Then Exit Do End If Next Loop Next End Sub

  • [java] How to get ALL the information from a socket

    - by raven
    Hello, I'll begin this question with the claim that I have read the java networking guide before asking you. I do not understand how to READ the socket and get all the info summed up into a string. the socket might contains more than 1 line [trying to make a chat]. Please do no refer me to any other site unless it clearly states "this exact line does this.." because I failed to understand what this code part does BufferedReader stdIn = new BufferedReader( new InputStreamReader(System.in)); String userInput; while ((userInput = stdIn.readLine()) != null) { out.println(userInput); System.out.println("echo: " + in.readLine()); } Please, I just want to make a loop that will receive information from a socket, get all the content together into one string [I also want it to know where to add another line]. Thanks allot for anyone who helps, I have been trying to get an answer from tuts for hours and just failed to understand!

  • Loop function works first time, not second time

    - by user1483101
    I'm creating a parsing program to look for certain strings in a a text file and count them. However, I'm having some trouble with one spot. def callbrowse(): filename = tkFileDialog.askopenfilename(filetypes = (("Text files", "*.txt"),("HTML files", ".html;*.htm"),("All files", "*.*"))) print filename try: global filex global writefile filex = open(filename, 'r') print "Success!!" print filename except: print "Failed to open file" ######This returns the correct count only the first time it is run. The next time it ######returns 0. If the browse button is clicked again, then this function returns the ######correct count again. def count_errors(error_name): count = 0 for line in filex: if error_name == "CPU > 79%": stringparse = "Utilization is above" elif error_name == "Stuck touchscreen": stringparse = "Stuck touchscreen" if re.match("(.*)" + "Utilization is above" + "(.*)",line): count = count + 1 return count Thanks for any help. I can't seem to get this to work right.

  • loop prematurely quitting

    - by Nick Gibson
    This loop works fine but prematurely quits at times. I set a piece of code in it so that I can view the random number. It only closes prematurely when the random number is equal to the highest numbered question the user inputs (Example...a user wants 10 questions, if the random number is 10 the program quits.) I have no idea why since i have it set to if(random number <= the number of questions) for ( int loop = 1; loop < loopCount; loop++ ) { aa = r.nextInt ( 10 + 1 ); abc = ( int ) aa; String[] userAnswer = new String[x]; JOptionPane.showMessageDialog ( null, abc ); if ( abc <= x ) { for ( overValue = 1; overValue < forLoop; overValue++ ); { userAnswer[j] = JOptionPane.showInputDialog ( null, "Question " + quesNum + "\n" + questions[abc] + "\n\nA: " + a[abc] + "\nB: " + b[abc] + "\nC: " + c[abc] + "\nD: " + d[abc] ); if ( userAnswer[j].equals ( answers[j] ) ) { JOptionPane.showMessageDialog ( null, "Correct. \nThe Correct Answer is " + answers[abc] ); } else { JOptionPane.showMessageDialog ( null, "Wrong. \n The Correct Answer is " + answers[abc] ); }//else }//for }//if }//for

  • How to iterate over numerically named object properties

    - by Scott Schluer
    So I have a horribly designed class that I can't change that has properties like this: object.Color1 object.Color2 object.Color3 etc... How can I iterate through those with a for loop. In other words, something like this: for (int i = 0; i <= 40; i++) { string PropertyName = "Color" + i; if (object.PropertyName != "") { // do something } } Obviously this code wouldn't work but it gives you an idea of what I'm after. I have to do some processing on each property and I don't want to repeat my code 40 times. :) A loop would be perfect, I'm just not sure how to create the name of the property on the fly.

  • Identify words with ascending characters from text file

    - by user2914000
    I am having a fair amount of trouble trying to write a program that counts the amount of ascending words (words in which each character is larger than the previous character) in a text file. I have tried a few different methods to solve this but cannot seem to get it working. If anyone could help me revise the code to work properly it would be appreciated. The code will print about 5 of the words from the list of nearly 20000, but none considered are ascending (the file does have many ascending words) and it sometimes prints the same word twice. I am printing theWord to the console simply to see if the code works. import java.util.Scanner; import java.io.*; public class { public static void main (String [] args) throws FileNotFoundException{ String theWord; Scanner inputFile = new Scanner(new File("file.txt")); boolean ascending = true; int i = 1; while(inputFile.hasNextLine()){ theWord = inputFile.nextLine(); if(theWord.length() >= 2){ while(i < theWord.length() - 1){ if(theWord.charAt(i) <= theWord.charAt(i + 1)){ ascending = true; System.out.println("+ " + theWord); totalNum = totalNum + 1; } else{ ascending = false; System.out.println("= " + theWord); } i++; } } }

  • How to do a for loop in windows command line?

    - by TheFoxx
    I was wondering if this was possible? I'm not familiar with using windows command line, but I have to use it for a project I'm working on. I have a a number of files, for which I need to perform a function for each. I'm used to working with python, but obviously this is a bit different, so I was hoping for some help. Basically I need the for loop to iterate through 17 files in a folder, perform a function on each (that's using the specific software I have here for the project) and then that will output a file with a unique name (the function normally requires me to state the output file name) I would suck it up and just do it by hand for each of the 17, but basically it's creating a database of a file, and then comparing it to each of the 17. It needs to be iterated through several hundred times though. Using a for loop could save me days of work. Suggestions?

    Hi there, I would like to know how can I get certain inputs and put them in more than one row in the structure ... I basically want a structure that updates one input per row in ever loop. The loop is looped 30 times, so I want to have 30 rows and 2 columns ( x and y columns) I have this code : For N=1:30 . . .

  • Java - Can i have a faster performance for this loop ?

    - by Brad
    I am reading a book and deleting a number of words from it. My problem is that the process takes long time, and i want to make its performance better(Less time), example : Vector<String> pages = new Vector<String>(); // Contains about 1500 page, each page has about 1000 words. Vector<String> wordsToDelete = new Vector<String>(); // Contains about 50000 words. for( String page: pages ) { String pageInLowCase = page.toLowerCase(); for( String wordToDelete: wordsToDelete ) { if( pageInLowCase.contains( wordToDelete ) ) page = page.replaceAll( "(?i)\\b" + wordToDelete + "\\b" , "" ); } // Do some staff with the final page that does not take much time. } This code takes around 3 minutes to execute. If i skipped the loop of replaceAll(...) i can save more than 2 minutes. So is there a way to do the same loop with a faster performance ?
