  • Trying to create a group of button sprites

    - by user1449653
    Good day, I have like 15 images I need to be buttons. I have buttons working with a Box() (Box - looks like this) class Box(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.Surface((35, 30)) self.image = self.image.convert() self.image.fill((255, 0, 0)) self.rect = self.image.get_rect() self.rect.centerx = 25 self.rect.centery = 505 self.dx = 10 self.dy = 10 I am trying to make the buttons work with image sprites. So I attempted to copy the class style of the box and do the same for my Icons.. code looks like this... class Icons(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/airbrushIC.gif").convert() self.rect = self.image.get_rect() self.rect.x = 25 self.rect.y = 550 the code in the main() rect = image.get_rect() rect.x = 25 rect.y = 550 ic1 = Icons((screen.get_rect().x, screen.get_rect().y)) screen.blit(ic1.image, ic1.rect) pygame.display.update() This code produces a positional (accepts 1 argument but 2 are there) error or an image is not referenced error (inside the Icon class). I'm unsure if this is the right way to go about this anyways.. I know for sure that I need to load all the images (as sprites)... store them in an array... and then have my mouse check if it is clicking one of the items in the array using a for loop. Thanks. EDIT QUESTION 2: class Icons(pygame.sprite.Sprite): def init(self, *args): pygame.sprite.Sprite.init(self, *args) self.image = pygame.image.load("images/airbrushIC.gif").convert() self.rect = self.image.get_rect() ic1 = self.image self.rect.x = 10 self.rect.y = 490 self.image = pygame.image.load("images/fillIC.gif").convert() self.rect = self.image.get_rect() ic2 = self.image self.rect.x = 10 self.rect.y = 540 Thanks to your help I got the Icons class loading ONE image. Its not loading both. Obviously because its being overwritten by the second one. It seems that "class" for this purpose isn't what I need. Which begs the question how I make sprites outside of a class.. If there is a way to make the class work please let me know.

  • Pass Element value to $ajax->link in cakephp

    - by TwoThumbs
    I need to pass the value of an element to an $ajax-link without using a form/submit structure. (because I have a dynamically set number of clickable links through which I am triggering the action) I used to do this in Ruby using the Prototype javascript function $F like this: <%= link_to_remote "#{item.to_s}", :url => { :action => :add_mpc }, :with => "'category=' + $F('mpc_category')" -%> But this does not seem to work in Cakephp: <?php echo $ajax->link(substr($vehicle['vehicles']['year'], -2), array('action' => 'add_mpc', 'category' => '$F("mpc_category")'), array('update' => 'results', 'position' => 'top')); ?> PHP sees $F as a variable instead of a call to javascript. I'm not too familiar with Javascript, but is there another way to pass the value of the 'mpc_category' input element to the controller through this link? I have been looking for a couple days and can't find anyone dealing with this specific issue. Thanks for any assistance. Edit: fixed syntax in php statement.

  • "Add another item" form functionality

    - by GSTAR
    I have a form that lets a user enter their career history - it's a very simple form with only 3 fields - type (dropdown), details (textfield) and year (dropdown). Basically I want to include some dynamic functionality whereby the user can enter multiple items on the same page and then submit them all in one go. I had a search on Google and found some examples but they were all based on tables - my markup is based on DIV tags: <div class="form-fields"> <div class="row"> <label for="type">Type</label> <select id="type" name="type"> <option value="Work">Work</option> </select> </div> <div class="row"> <label for="details">Details</label> <input id="details" type="text" name="details" /> </div> <div class="row"> <label for="year">Year</label> <select id="year" name="year"> <option value="2010">2010</option> </select> </div> </div> So basically the 3 DIV tags with class "row" need to be duplicated, or to simplify things - the div "form-fields" could just be duplicated. I am also aware that the input names would have to converted to array format. Additionally each item will require a "remove" button. There will be a main submit button at the bottom which submits all the data. Anyone got an elegant solution for this?

  • What is a more "ruby way" to write this code?

    - by steadfastbuck
    This was a homework assignment for my students (I am a teaching assistant) in c and I am trying to learn Ruby, so I thought I would code it up. The goal is to read integers from a redirected file and print some simple information. The first line in the file is the number of elements, and then each integer resides on its own line. This code works (although perhaps inefficiently), but how can I make the code more Ruby-like? #!/usr/bin/ruby -w # first line is number of inputs (Don't need it) num_inputs = STDIN.gets.to_i # read inputs as ints h = Hash.new STDIN.each do |n| n = n.to_i h[n] = 1 unless h[n] and h[n] += 1 end # find smallest mode h.sort.each do |k,v| break puts "Mode is: #{k}", "\n" if v == h.values.max end # mode unique? v = h.values.sort print "Mode is unique: " puts v.pop == v.pop, "\n" # print number of singleton odds, # odd elems repeated odd number times in desc order # even singletons in desc order odd_once = 0 odd = Array.new even = Array.new h.each_pair do |k, v| odd_once += 1 if v == 1 and k.odd? odd << k if v.odd? even << k if v == 1 and k.even? end puts "Number of elements with an odd value that appear only once: #{odd_once}", "\n" puts "Elements repeated an odd number of times:" puts odd.sort.reverse, "\n" puts "Elements with an even value that appear exactly once:" puts even.sort.reverse, "\n" # print fib numbers in the hash class Fixnum def is_fib? l, h = 0, 1 while h <= self return true if h == self l, h = h, l+h end end end puts "Fibonacci numbers:" h.keys.sort.each do |n| puts n if n.is_fib? end

  • How to randomly assign a partner?

    - by David
    I asked a question some time ago about creating a random circular partner assignment using php and mysql. This is a related issue. I am working from the following code to try to give two users new, randomly selected partners: $q = "SELECT user_id FROM users WHERE partner='$quit_partner' AND status='1'"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); while ($row = mysqli_fetch_array($r)) { $users[] = $row[0]; } $current = end($users); $partners = array(); foreach ($users as $user) { $partners[$user] = $current; $current = $user; $q = "UPDATE users SET partner='{$partners[$user]}' WHERE user_id='{$user}'"; mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); } Basically, a particular user (lets say user #4) quits the activity, leaving multiple other users without a partner (hypothetically, users # 5,6,7). I need to find out who those users are, hence the first query. Once I find them, I throw them into an array. Then comes the difficult part. I want those newly partnerless users (5,6,7) to be randomly assigned new partners from everyone in the table. The current code is flawed in that it only assigns the newly partnerless users eachother. Thanks for your help.

  • Java: How ArrayList memory management

    - by cka3o4nik
    In my Data Structures class we have studies the Java ArrayList class, and how it grows the underlying array when a user adds more elements. That is understood. However, I cannot figure out how exactly this class frees up memory when lots of elements are removed from the list. Looking at the source, there are three methods that remove elements: [code] public E remove(int index) { RangeCheck(index); modCount++; E oldValue = (E) elementData[index]; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work return oldValue; } public boolean remove(Object o) { if (o == null) { for (int index = 0; index < size; index++) if (elementData[index] == null) { fastRemove(index); return true; } } else { for (int index = 0; index < size; index++) if (o.equals(elementData[index])) { fastRemove(index); return true; } } return false; } private void fastRemove(int index) { modCount++; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work } {/code] None of them reduce the datastore array. I even started questioning if memory free up ever happens, but empirical tests show that it does. So there must be some other way it is done, but where and how? I checked the parent classes as well with no success.

  • codeigniter avoiding html div's

    - by rabidmachine9
    Hello there!Is there a proper syntax to avoid div's in codeigniter? I don't really like opening and closing tags all the time... <div class="theForm"> <?php echo form_open('edit/links');//this form uploads echo "Enter the Name: ". form_input('name','name'); echo "Enter the Link: ". form_input('url','url'); echo " ".form_submit('submit', 'Submit'); echo form_close(); if (isset($linksQuery) && count($linksQuery)){ foreach($linksQuery as $link){ echo anchor($link['link'], $link['name'].".", array("class" => "links")); echo form_open('edit/links',array('class' => 'deleteForm')); echo form_hidden('name',$link['name']); echo " ".form_submit('delete','Delete'); echo form_close(); echo br(2); } } ?> </div>

  • What is the most efficient way to handle points / small vectors in JavaScript?

    - by Chris
    Currently I'm creating an web based (= JavaScript) application thata is using a lot of "points" (= small, fixed size vectors). There are basically two obvious ways of representing them: var pointA = [ xValue, yValue ]; and var pointB = { x: xValue, y: yValue }; So translating my point a bit would look like: var pointAtrans = [ pointA[0] + 3, pointA[1] + 4 ]; var pointBtrans = { x: pointB.x + 3, pointB.y + 4 }; Both are easy to handle from a programmer point of view (the object variant is a bit more readable, especially as I'm mostly dealing with 2D data, seldom with 3D and hardly with 4D - but never more. It'll allways fit into x,y,z and w) But my question is now: What is the most efficient way from the language perspective - theoretically and in real implementations? What are the memory requirements? What are the setup costs of an array vs. an object? ... My target browsers are FireFox and the Webkit based ones (Chromium, Safari), but it wouldn't hurt to have a great (= fast) experience under IE and Opera as well...

  • Can anyone help with this (Javascript arrays)?

    - by Rich
    Hi I am new to Netui and Javascript so go easy on me please. I have a form that is populated with container.item data retuned from a database. I am adding a checkbox beside each repeater item returned and I want to add the container item data to an array when one of the checkboxes is checked for future processing. The old code used Anchor tag to capture the data but that does not work for me. <!--netui:parameter name="lineupNo" value="{container.item.lineupIdent.lineupNo}" /> here is my checkbox that is a repeater. <netui:checkBox dataSource="{pageFlow.checkIsSelected}" onClick="checkBoxClicked()" tagId="pceChecked"/> this is my Javascript function so far but I want to a way to store the container.item.lineupIdent.lineupNo in the array. function checkBoxClicked() { var checkedPce = []; var elem = document.getElementById("PceList").elements; for (var i = 0; i < elem.length; i ++) { if (elem[i].name == netui_names.pceChecked) { if (elem[i].checked == true) { //do some code. } } } } I hope this is enough info for someone to help me. I have searched the web but could not find any examples. Thanks.

  • Custom punctuation function making script run over the php's 60s runtime limit

    - by webmasters
    I am importing allot of product data from an XML file (about 5000 products). When I run the script I can make it work in about 10-12 seconds. Now, when I add this punctuation function which makes sure each product description ends with a punctuation sign, the code runs until the php 60 seconds loadtime on my server but I'm not getting any errors. I have error reporting turned on. I just get a final error that the script could not load in 60 seconds. The question is, looking at this function, is it that resource consuming? What can I do to make it faster? function punctuation($string){ if(strlen($string) > 5){ // Get $last_char $desired_punctuation = array(".",",","?","!"); $last_char = substr($string, -1); // Check if $last_char is in the $desired_punctuation array if(!in_array($last_char, $desired_punctuation)){ // strip the $mytrim string and get only letters at the end; while(!preg_match("/^[a-zA-Z]$/", $last_char)){ $string = substr($string, 0, -1); $last_char = substr($string, -1); } // add "." to the string $string .= '.'; } } return $string; } If the function is ok, the long runtime must come from something else which I'll have to discover. I just want your input on this part.

  • PasswordFiled char[] to String in Java connection MySql?

    - by user1819551
    This is a jFrame to connect to the database and this is in the button connect. My issue is in the passwordField NetBeans make me do a char[], but my .getConnection not let me insert the char[] ERROR: "no suitable method found for getConnection(String,String,char[])". So I will change to String right? So when I change and run the jFrame said access denied. when I start doing the System.out.println(l) " Give me the right answer" Like this: "Alex". But when I do the System.out.println(password) "Give me the Array spaces and not the value" Like this: jdbc:mysql://localhost/home inventory root [C@5be5ab68 <--- Array space .

    probably this is a simple problem to solve, since I'm quite new. I have a scene with a waiter holding a tray of food (the food is a random CCSprite choosen from an array) each time he comes onscreen he holds a new piece of food (the user touches the food and the waiter walks off to return again with a new piece of food however I cant seem to delete the old peice of food from the screen as it says the child is already added... any help would be great -(id) init { ///other code then... waiterOnSCreen = [CCSprite spriteWithSpriteFrameName:@"CatUP.png"]; waiterOnSCreen.position = ccp(CatOffSCreenPosX, catXpos); [self addChild:waiterOnSCreen z:0]; //moving the waiter // the random food sprite is added later to the waiter // [waiterOnSCreen addChild:myRandomSprite]; } -(void)LoadRandomFood { ///I make my array here then... int i = arc4random() % [RandomFood count]; myRandomSprite = (CCSprite *)[RandomFood objectAtIndex:i]; //waiterOnSCreen is a CCSprite added on the init [waiterOnSCreen addChild:myRandomSprite]; myRandomSprite.position=ccp(290,220); myRandomSprite.tag = RandomFoodTag; } } later in if(CGRectContainsPoint(waiterOnSCreen.boundingBox, location)) { //trying to remove the food here //Ive already tried to remove the sprite using [self removeChildByTag:RandomeObjectTag]; //and also CCSprite *wantedSprite = (CCSprite *)[self getChildByTag:RandomFoodTag]; [wantedSprite removeFromParentAndCleanup:YES]; } }

  • matching images inside a link in regex

    - by user225269
    What is wrong with regex pattern that I created: $link_image_pattern = '/\<a\shref="([^"]*)"\>\<img\s.+\><\/a\>/'; preg_match_all($link_image_pattern, $str, $link_images); What I'm trying to do is to match all the links which has images inside of them. But when I try to output $link_images it contains everything inside the first index: <pre> <?php print_r($link_images); ?> </pre> The markup looks something like this: Array ( [0] = Array ([0] = " <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p> But when outputting the contents of the matches, it simply returns the first string that matches the pattern plus all the other markup in the page like this: <a href="{$image_url}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url}" width="568" height="347"></a></p> <p>&nbsp;</p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p>")

  • Is there any well-known paradigm for iterating enum values?

    - by SadSido
    I have some C++ code, in which the following enum is declared: enum Some { Some_Alpha = 0, Some_Beta, Some_Gamma, Some_Total }; int array[Some_Total]; The values of Alpha, Beta and Gamma are sequential, and I gladly use the following cycle to iterate through them: for ( int someNo = (int)Some_Alpha; someNo < (int)Some_Total; ++someNo ) {} This cycle is ok, until I decide to change the order of the declarations in the enum, say, making Beta the first value and Alpha - the second one. That invalidates the cycle header, because now I have to iterate from Beta to Total. So, what are the best practices of iterating through enum? I want to iterate through all the values without changing the cycle headers every time. I can think of one solution: enum Some { Some_Start = -1, Some_Alpha, ... Some_Total }; int array[Some_Total]; and iterate from (Start + 1) to Total, but it seems ugly and I have never seen someone doing it in the code. Is there any well-known paradigm for iterating through the enum, or I just have to fix the order of the enum values? (let's pretend, I really have some awesome reasons for changing the order of the enum values)...

  • Maintaining Mouse Control in Embedded swfs (i.e. parent / child ) Flash cs4 AS3

    - by garydev
    Hello to all, I have an issue that is driving me nuts. I have an AS3 application that performs a calculation based upon user's input to determine a result. The purpose is to predict the results of a horse's coat color based on the genetics. The results are given in a 3d model swfs that are loaded into the "shell's" UILoader Component and they rotate. I have an example of this here: http://www.provideoshow.com/coatcalculator/coat_calculator.html As you can see this works fine with an "auto-rotate" feature. The problem is that my client wants the 3d models to be rotated by the user's mouse. I have the 3d models rotating with the mouse but they only work when they are stand alone swfs. They break when they are loaded into the shell. Some research informs me that the issue is in the stage properties and the parent not receiving them from the child. I've gotten some advice that I need to pass a reference to the shell's stage and preferably in the init function. This is the code I have in the child which is loaded as a class public function Main_master_withmouse() { if(stage) { _stage = stage; init(stage); } } protected function init(rootStage:Stage):void { if(rootStage) { _stage = rootStage; } else { _stage = this.stage; } sceneWidth = _stage.stageWidth createChildren(); startRendering(); } I can't figure out what to put in the parent to pass the reference to its stage. Any help is greatly appreciated. Thank you in advance

  • how to filter text of the selected value in drop down

    - by Carlos
    I have a drop down menu. Has product types. Product types have associated value (from drop down) values correspond to machine groups. So each option should have three variables--Machine name, values, machine group. I can get the Machine name and I can get the machine value (and display them in a different field)...what I have not been able to figure out is how to change the value into the Machine group. jQuery('#MachineName').bind('change', function() { //get selected value from drop down; var selectedValue = jQuery("#MachineName").val(); //populate a text field with the selected drop down value jQuery("#MachineValue").val(selectedValue); What I would like to do is keep that MachineValue but then populate another text field with the sorted MachineGroup I have been trying to run it through something like switch(jQuery(this).val()){ case "236" : newVal = "8"; break; But I don't want to "change" the value I just want to do an "if then" type filter, so maybe something like: '236' => "8", '237' => "5", I just don't know how to properly say "assign the MachineGroup based on the MachineValue" (and then have it populate a different text field) In the end I would have three fields. The drop down, the MachineValue and the MachineGroup. Drop down and value are done, I just need to do Group. (And I can sort Group based on MachineName...just not sure which would be easier)

  • [Processing/Java]Visibility/Layering Issue

    - by nnash
    I'm working on a small sketch in processing where I am making a "clock" using the time functions and drawing ellipses across the canvas based on milliseconds, seconds and minutes. I'm using a for loop to draw all of the ellipses and each for loop is inside its own method. I'm calling each of these methods in the draw function. However for some reason only the first method that is called is being drawn, when ideally I would like to have them all being visibly rendered. //setup program void setup() { size(800, 600); frameRate(30); background(#eeeeee); smooth(); } void draw(){ milliParticles(); secParticles(); minParticles(); } //time based particles void milliParticles(){ for(int i = int(millis()); i >= 0; i++) { ellipse(random(800), random(600), 5, 5 ); fill(255); } } void secParticles() { for(int i = int(second()); i >= 0; i++) { fill(0); ellipse(random(800), random(600), 10, 10 ); background(#eeeeee); } } void minParticles(){ for(int i = int(minute()); i >= 0; i++) { fill(50); ellipse(random(800), random(600), 20, 20 ); } }

  • Is it possible to reference remote content from chrome.manifest? (XULRunner)

    - by siemaa
    Hi, I have a xulrunner application and I've been trying to reference remote content from chrome.manifest file. Tt's an application for the company I work in; it's run on a number of computers (most of them are used by other employees as well) as a kind of an internet monitoring service. The problem I'd like to solve is this: updating the code of such application usually requires me to manually copy the modified files to every computer that the application is running on (I've had no luck trying to make automatic updates via xulrunner platform). This process has become very tedious. What I'd like to have is a web server, where all of the xul and js files would be accessible, so that every application could reference them from there. This would require me only to update the code on that server, and the applications (when restarted) would automatically get the latest code. What I managed to do: I can reference js scripts from a xul file using http based urls and everything works fine (I can use local, binary components etc.), although the xul file has to be local - that I'd like to change. But when I write in chrome.manifest a line like: content my_app http://path/to/app/files/ and then use the line in default/preferences/pref.js pref("toolkit.defaultChromeURI", "chrome://my_app/content/my_app.xul"); it just opens a console window (to test I manually run the application with the -console option) and no code gets executed. The file can be downloaded remotely using wget so I guess this isn't the web server issue. The applications work on Windows machines. Is there some kind of security issue causing such behavior or am I doing something wrong? Is it even possible to register remote, http based content as chrome?

The Flash detection script is as follows, using jquery 1.8.2 and jquery.jqplugin 1.0.2 <script type="text/javascript" src="jquery-1.8.2.min.js"></script> <script type="text/javascript" src="jquery.jqplugin.1.0.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#withflash").hide(); $("#noflash").hide(); if ($.browser.flash == true) $("#withflash").show (); else $("#noflash").show (); }); </script> <div id="withflash">Flash Supported</div> <div id="noflash">Flash Not Supported</div> I get the display that "Flash Supported" if Flash Plugin is present.. I need to capture the value whether flash plugin value is true in a php variable $hasFlashSupport as below: <?php echo " $hasFlashSupport"; exit; ?> I am aware that PHP is server based and Javascript is client based.. Hence Ajax would be a nice option to capture the javascript variable to my php variable. I am totally ignorant about Ajax syntax and how to achieve it. Request the experts here to help me out with the code on how this can be achieved... Thanking all of you in advance..

  • Win conditions for a connect-4 like game

    - by FrozenWasteland
    I have an 5x10 array that is populated with random values 1-5. I want to be able to check when 3 numbers, either horizontally, or vertically, match. I can't figure out a way to do this without writing a ton of if statements. Here is the code for the randomly populated array int i; int rowincrement = 10; int row = 0; int col = 5; int board[10][5]; int randomnum = 5; int main(int argc, char * argv[]) { srand(time(NULL)); cout << "============\n"; while(row < rowincrement) { for(i = 0; i < 5; i++) { board[row][col] = rand()%5 + 1; cout << board[row][col] << " "; } cout << endl; cout << "============\n"; row++; } cout << endl; return 0; }

  • When to pass pointers in functions?

    - by yCalleecharan
    scenario 1 Say my function declaration looks like this: void f(long double k[], long double y[], long double A, long double B) { k[0] = A * B; k[1] = A * y[1]; return; } where k and y are arrays, and A and B are numerical values that don't change. My calling function is f(k1, ya, A, B); Now, the function f is only modifying the array "k" or actually elements in the array k1 in the calling function. We see that A and B are numerical values that don't change values when f is called. scenario 2 If I use pointers on A and B, I have, the function declaration as void f(long double k[], long double y[], long double *A, long double *B) { k[0] = *A * *B; k[1] = *A * y[1]; return; } and the calling function is modified as f(k1, ya, &A, &B); I have two questions: Both scenarios 1 and 2 will work. In my opinion, scenario 1 is good when values A and B are not being modified by the function f while scenario 2 (passing A and B as pointers) is applicable when the function f is actually changing values of A and B due to some other operation like *A = *B + 2 in the function declaration. Am I thinking right? Both scenarios are can used equally only when A and B are not being changed in f. Am I right? Thanks a lot...

  • Using AJAX to POST data to PHP database, then refresh

    - by cb74656
    Currently I have a button: <ul> <li><button onclick="display('1')">1</button></li> <li><button onclick="display('2')">2</button></li> <li><button onclick="display('3')">3</button></li> </ul> That when pressed, calls a javascript function, and displays PHP based on which button is pressed using AJAX. I figured this out all on my own. The AJAX gets a PHP file with a postgres query that outputs a table of data to a div. Now I want to be able to add, via form, new data and have it refresh (without reloading the page, yannknow?). I've tried a couple of things, and have hit roadblocks every time. My initial idea was to have the form submit the data using a javascript function and AJAX, then call my "display()" function after the query to reload the content. I just can't figure it out using GoogleFu. Based on my current idea, I'd like help with the following: How do I pass the form data to a javascript function. How do I use POST to pass that data to PHP using AJAX? I'm super new to javascript and AJAX. I've looked into jquery as it seems like that's the way to go, but I can't figure it out. If there's a better way to do this, I'm open to suggestions. Please forgive any misuse of nomenclature. EDIT: Once I solve this problem..., I'll have all the tools needed to finish the project preliminarily.
