  • how to do collision detection for hollow(?) movieclips in flash AS3?

    - by Pieter888
    Hey everyone, I'm making small interactive games in flash to learn AS3, now I ran into a problem that I need some help with. I need to check the collision between the player and the wall which is normally simple using the hitTestObject function. But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object. So assuming that I'm correct about the error: How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?

    - by user2798091
    I am trying to build a tile calculator but can't seem to get the following code to work: JQuery: $(document).ready( function caculateForm() { var length = document.getElementById('length').value; var width = document.getElementById('width').value; var size = document.getElementById('size').value; var compute = (length * width) / (size / 100); var total = compute * 100; var allowance = (compute * 100) * .10; allowance = Math.floor(total) + Math.floor(allowance + 1); document.getElementById('total').value = Math.floor(total); document.getElementById('allowance').value = allowance; } }); $(document).ready( function clearFileInput(id) { var elem = document.getElementById(id); elem.parentNode.innerHTML = elem.parentNode.innerHTML; } }); Here is my jsfiddle

  • Can a link have both an onclick jquery and javascript event?

    - by odpogn
    I have a link that jQuery listens to, and if clicked it will toggle another div. The link also has an onclick javascript action. When I click the link, the div I want to toggle shows, but the javascript doesn't execute. Is it possible to get the javascript to execute AND have jQuery toggle the div? If so what would I put in the jQuery code to allow the link to execute the onclick javascript action? jQuery script $(function() { $('#links a').live('click', function() { $("#showall").toggle('slow'); }); }); my link <div id ="links"> <a href="some javascript" onclick="javascript">Play</a> </div>

  • MovieClip progress bar width is too small relative to parent container

    - by egyedg
    I am new to ActionScripot and Flash and I am stuck with the following problem: On the stage I have a movieclip (Container, originally 200px width) and inside it with a progressbar movieclip (originally 700px width), scaled with Free Transform Tool to fit the parent container. The width of the container changes run-time while resizing the scene. In ActionScript I have a function which should set the progress bar width according to a calculated percentage value: private function updateProgress(event:TimerEvent):void { var barWidth:int = _container.width; var progress:Number = _stream.time / _stream.duration * barWidth; _progressBar.width = progress; } My problem is that the progressBar even at full time (100%) is only at 1/4 of the parent container. I assume that it comes from the symbols original size. Can I correct this programatically, or I must redesign it with the "designer"? I hope I made clear my problem, as I said, I'm new in Flash. Thanks in advance.

  • Running a piece of code for a certain amount of time in C#?

    - by Hazem
    Hi I am working on a robot that is capable of motion detection using a webcam. I am doing this in C# The robot moves too fast, so I want to turn it on/off at short time intervals in order to reduce its speed. For example, it will start the engine then wait 0.5 second and turn it off, this cycle repeats every 2 seconds. This way, its speed wont be too fast. I would like to include this in a single function called Move() I just don't know how to do this, especially because my motion detection code runs like 20 times a second. Depending on the position of the obstacle, I may need to disable the Move() function and activate other functions that let the robot move into other directions. Any ideas/suggestions on where am I supposed to start? Thanks a lot!

  • Jquery: Setting permanent height to an specific tab & resize plugin

    - by charlieCodex
    I am working with jquery sliding tabs. I have found a resize plugin that helps the tabs adjust to expanding content. The only thing is that i want to set a permanent height to tab 1(st_content_1). The code i have below works but it is a bit faulty. Should place in the function if statements? Check for the height of the first tab and then set it? Or a any better solution? You can check my EXAMPLE. Jquery $('.st_tab_view').resize(function() { var height = 250 $('div#st_content_1').css('height', height+'px'); var $this = $(this); $this.closest('.st_view').css('height', $this.height()); });

  • mysql_close(): supplied argument is not a valid MySQL-Link resource

    - by maxedison
    I'm trying to get the hang of using custom session handlers to store session data in a MySQL database. However, I keep getting the following warning: mysql_close(): supplied argument is not a valid MySQL-Link resource Here's the code I'm using, which I got from here: function _open(){ global $_sess_db; $_sess_db = mysql_connect("localhost", "root", "******"); if ($_sess_db) { return mysql_select_db('style', $_sess_db); } return false; } function _close(){ global $_sess_db; return mysql_close($_sess_db); //error happens here } The full text of the error message ultimately points to the final "return mysql_close($_sess_db);" line. I can confirm that the mysql_connect info does in fact work, and I do have the rest of the session handler functions defined as well. And in case it helps, I get these errors immediately upon page load, without actually calling any of the session handler functions, and without having any current sessions open.

  • Append an onClick event to an anchor tag using jquery?

    - by M.Woodard
    I am trying to add an onClick event to an anchor tag ... Previously i had ... <a href="somlink.html" onClick="pageTracker._link(this.href); return false;"> But i am trying to avoid the inline onClick event because it interferes with another script.. So using jQuery i am trying the following code ... <script> $(document).ready(function() { $('a#tracked').attr('onClick').click(function() {window.onbeforeunload = null; pageTracker._link(this.href); return false; }); }); </script> with the html like so <a id="tracked" href="something.html"> So my question is should this be working, and if not what would be the best solution?

  • Getting URL of executing JavaScript file (IE6-7 problem mostly)...

    - by TooTallNate
    Hey all, I've been trying to throw together a generic function that retrieves the absolute URL of an executing JavaScript file on a web page: http://gist.github.com/433486 It works great in almost all the browsers I've tested (Firefox, Chrome, Safari, Opera v10 at least, and IE 8). It seems to fail, however, in IE 6 and 7. The callback function gets executed, but the retrieved name is simple the URL to the main HTML page, not the JavaScript file. So all I'm really asking is if there's some other way of getting the URL of the current JavaScript file (which could be IE 6 and 7 specific)? Thanks in advance!

  • using jquery $.post() for returning multiple values

    - by Aninemity
    Hi all I am trying to use a $.post() in the following way: $.post("file.php", { file_id: $(this).val()}, function(data){...} The file.php then does a database query and returns an array with a title, description and image reference. What I want to do then is be able to update the .val() for form fields for each. I understand how to do this on a single variable, it would just be the following: $.post("file.php", { file_id: $(this).val()}, function(data){ $('#title').val(data); } But, how do I get the data returned to be recognizable in jquery as either separate variables or as an array? Thanks in advance

  • Macros giving problems with dladdr()

    - by Veger
    I have implemented tracing behavior using the -finstrument-functions option of gcc and this (simplified) code: void __cyg_profile_func_enter(void *this_fn, void *call_site) { Dl_info di; if(dladdr(this_fn, &di)) printf("entered %s\n", (di.dli_sname?di_dli_sname:"<unknown>")); } This works great, except for one thing: macros are processed as well, but the function prints the information of the function which contains the macro. So functions containing macros have their information printed multiple times (which is of course undesired). Is there anything to detect that a macro is being processed? Or is is possible to turn off instrumenting macros at all? PS Same problems occur with sizeof()

  • CSS and JQuery: spaces inside image name break code of url()

    - by Shyam
    Hi, I have a page that is supposed to display a larger version of an image when hovered over a thumbnail. I have a 'div' with an ID and the JQuery code is as following: $(document).ready(function(){ $('img').hover(function() { var src = $("#im" + this.id).attr("src"); $('#viewlarge').css('backgroundImage','url(' + src +')'); return false; }); }); The images I use, are generated by a Ruby script that "generate" an image with a similar, yet different id. However, sometimes, photo's are uploaded that have "spaces" inside. My developer tools tell me that the background-image is not set correctly, yet the image path is correct and the browser don't have problems finding the image. My question is, can I somehow sanitize the url 'src', so spaces won't be a problem? I am aware of doing this server side, yet I would like to know how to do this with JQuery/JS too. Thanks!

  • dynamically double image size

    - by Edan Duarte
    I have an embarrassingly simple question: How can I display an image at double its size without hard coding the width and height attributes? Here's what I tried, but I ended up having to just enter 1000 for width and height. Is something wrong with my function? Thanks! <img onload="double(self.id);" name="bigPic" id="bigPic" src="album1.jpg" height="1000" width="1000"/> function double(id) { var img = document.getElementById(id); var dblWdth = img.width * 2; var dblHt = img.height * 2; img.height = dblHt; img.width = dblWdth; }

  • Slide Effect happening too many times

    - by Abs
    Hello all, I call this functions on onmouseover and onmouseout for several divs. //Takes effect on divs with id, 62,63,64,65... function slide_it(id){ $('#options_'+id).slideToggle('slow'); } The problem is that if I move my mouse over and then mouse out, then again, mouse over and then mouse out. If I do this several times, the slide effect happens the same number of times I moved my mouse over and out of the div, as expected. But I can't figure out how I can do this once? I can set a variable, but I have several divs that this function is used by and I can't think of a simple way of doing this rather than storing things into an array, but this is messy! I really appreciate any help on this that is simple to implement! Thanks all for any help

  • "this" in JavaScript

    - by cf_PhillipSenn
    I'm trying to understand the syntax of how to put together a JavaScript function as an object. Q: Is this the right way to do it? The reason why I ask is because I'm looking at it in Firebug and I was hoping to be able to drill down and see the value of myVar and myVariable, but instead Firebug only says that "this" is an object Object. var myObject = { init: function() { var myVar = 1; myObject.myVariable = 2; console.log('"this" when called as an object: ' + this); } } myObject.init(); Also, what's the funny little syntax to call it directly upon declaration? Something about (), but when I remove the last line and put () at the end of the declaration, I get a syntax error.

(i don't want the Modelbinder to use New() and instantiate obj, but I want to deliver the object from a custom repository.) Is this possible? Edit: The loading from the repository should be done based on the id parameter of EditObject...

  • Next/Previous click jQuery UI

    - by madjester
    I am trying to add next/previous buttons on a button click using the jQuery UI Slider. I found this code... $("#down").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val - step); }); $("#up").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val + step); }); Here: http://osdir.com/ml/jquery-ui/2009-03/msg00617.html However this only changes the value of the Slider, moving the slider handle, but it doesn't actually slide the element. Little help?

  • Does '[ab]+' equal '(a|b)+' in python re module?

  • speeding up parsing of files

    - by user248237
    the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.) this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.) how can I speed it up? def csv2dictlist_raw(filename, delimiter='\t'): f = open(filename) header_line = f.readline().strip() header_fields = header_line.split(delimiter) dictlist = [] # convert data to list of dictionaries for line in f: values = map(tryEval, line.strip().split(delimiter)) dictline = dict(zip(header_fields, values)) dictlist.append(dictline) return (dictlist, header_fields) thanks.
