  • Modifying a model and texture mid-game code

    - by MicroPirate
    Just have a question for anyone out there who knows some sort of game engine pretty well. What I am trying to implement is some sort of script or code that will allow me to make a custom game character and textures mid-game. A few examples would be along the lines of changing facial expressions and body part positions in the game SecondLife. I don't really need a particular language, feel free to use your favorite, I'm just really looking for an example on how to go about this. Also I was wondering if there is anyway to combine textures for optimization; for example if i wanted to add a tattoo to a character midgame, is there any code that could combine his body texture and the tattoo texture into one texture to use (this way I can simply just render one texture per body.) Any tips would be appreciated, sorry if the question is a wee bit to vauge.

  • Characters in string changed after downloading HTML from the internet.

    - by Callum Rogers
    Using the following code, I can download the HTML of a file from the internet: WebClient wc = new WebClient(); // .... string downloadedFile = wc.DownloadString("http://www.myurl.com/"); However, sometimes the file contains "interesting" characters like é to é, ? to ↠and ????? to フシギダãƒ. I think it may be something to do with different unicode types or something, as each character gets changed into 2 new ones, perhaps each character being split in half but I have very little knowledge in this area. What do you think is wrong?

  • Forcing the Soft Keyboard open

    - by jax
    I am trying to force the Soft Keyboard open in an Activity and grab everything that is entered as I want to handle the input myself, I don't have an EditText. Currently I have tried this but it does not work. I would like the Soft Keyboardto open below mAnswerTextView (Note: it is a TextView not EditText). InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); // only will trigger it if no physical keyboard is open mgr.showSoftInput(mAnswerTextView, InputMethodManager.SHOW_IMPLICIT); how do I force the Soft Keyboard open How do I gab everything that is entered so that I can handle each character. I would like to flush each character from the imei after I have handled it. ie, the user should not be able to enter whole words in the Soft Keyboard.

  • Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

    - by Laurence Gonsalves
    Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

  • C# assign char and char array to string?

    - by Bopha
    char character = 'c'; string str = null; str = character.ToString();//this is ok char[] arrayChar = { 'a', 'b', 'c', 'd' }; string str2 = null; str2 = string.Copy(arrayChar.ToString());//this is not ok str2 = arrayChar.ToString();//this is not ok. I'm trying to converting char array to string, but the last two attempts don't work. Other source I found and they have to create new string type, but I don't know why. Can someone give me little explaination, thanks.

  • Purpose of Trigraph sequences in C++?

    - by Kirill V. Lyadvinsky
    According to C++'03 Standard 2.3/1: Before any other processing takes place, each occurrence of one of the following sequences of three characters (“trigraph sequences”) is replaced by the single character indicated in Table 1. ---------------------------------------------------------------------------- | trigraph | replacement | trigraph | replacement | trigraph | replacement | ---------------------------------------------------------------------------- | ??= | # | ??( | [ | ??< | { | | ??/ | \ | ??) | ] | ??> | } | | ??’ | ˆ | ??! | | | ??- | ˜ | ---------------------------------------------------------------------------- In real life that means that code printf( "What??!\n" ); will result in printing What| because ??! is a trigraph sequence that is replaced with the | character. My question is what purpose of using trigraphs? Is there any practical advantage of using trigraphs? UPD: In answers was mentioned that some European keyboards don't have all the punctuation characters, so non-US programmers have to use trigraphs in everyday life? UPD2: Visual Studio 2010 has trigraph support turned off by default.

  • Unescape _xHHHH_ XML escape sequences using Python

    - by John Machin
    I'm using Python 2.x [not negotiable] to read XML documents [created by others] that allow the content of many elements to contain characters that are not valid XML characters by escaping them using the _xHHHH_ convention e.g. ASCII BEL aka U+0007 is represented by the 7-character sequence u"_x0007_". Neither the functionality that allows representation of any old character in the document nor the manner of escaping is negotiable. I'm parsing the documents using cElementTree or lxml [semi-negotiable]. Here is my best attempt at unescapeing the parser output as efficiently as possible: import re def unescape(s, subber=re.compile(r'_x[0-9A-Fa-f]{4,4}_').sub, repl=lambda mobj: unichr(int(mobj.group(0)[2:6], 16)), ): if "_" in s: return subber(repl, s) return s The above is biassed by observing a very low frequency of "_" in typical text and a better-than-doubling of speed by avoiding the regex apparatus where possible. The question: Any better ideas out there?

  • is it possible to extract certain strings based off a predefined white-space count?

    - by s2xi
    So after several Advil's I think I need help I am trying to make a script that lets the user upload a .txt file, the file will look like this as an example EXT. DUNKIN' DONUTS - DAY Police vehicles remain in the parking lot. The determined female reporter from the courthouse steps, MELINDA FUENTES (32), interviews Comandante Chitt, who holds a napkin to his jaw, like he cut himself shaving. MELINDA < Comandante Chitt, how does it feel to get shot in the face? > COMANDANTE CHITT < Not too different than getting shot in the arm or leg. > MELINDA < Tell us what happened. > COMANDANTE CHITT < I parked my car. (indicates assault vehicle in donut shop) He aimed his weapon at my head. I fired seven shots. He stopped aiming his weapon at my head. > Melinda waits for more, but Chitt turns and walks away into the roped-off crime scene. Melinda is confused for a second, then resumes smiling. MELINDA < And there you have it... A man of few words. > Ok, so based off of this what I want to do is this: The PHP script looks at the file and counts 35 white spaces, since all files will have the same layout and never differ in white spaces I chose this as the best way to go. for every 35 white spaces extract character 36 until the end of line. Then tally up $character++ so in the end the output would look like ----------------------------------- It looks like you have 2 characters in your script Melinda Commandante Chitt ----------------------------------- using PHP to select distinct names, and use the strtolower() to lower case the strings and ucfirst() to make the first letter upper-case thats my project, I'm at the stage where I'm going crazy trying to figure out how to count white-spaces and everything after that white space until the first white-space after the word IS a character name

  • Another C datatypes question

    - by b-gen-jack-o-neill
    Hello. Well, I completely get the most basic datatypes of C, like short, int, long, float, to be exact, all numerical types.These types are needed to be known perform right operations with right numbers. For example to use FPU to add two float numbers. So the compiler must know what the type is. But, when it comes to characters I am little bit off. I know that basic C datatype char is there for ASCII characters coding. But what I don´t know is, why you even need another datatype for characters. Why could not you just use 1 byte integer value to store ASCII character. If you call printf, you apecify the datatype in the call, so you could say to printf that the integer represents ASCII character. I dont know how cout resolves datatype, but I guess you could just specify it somehow. Another thing is, when you want to use Unicode, you must use datatype wchar. But, what if I would like to use some another, for example ISO, or Windows coding instead of UTF? Becouse wchar codes characters as UTF-16 or UTF-32 (I read its compiler specific). And, what if I would want to use for example some imaginary new 8 byte text coding? What datatype should I use for it? I am actually pretty confused of this, becouse I always expected that if I want to use UTF-32 instead of ASCII, I just tell compiler "get UTF-32 value of the character I typed and save it into 4 char field." I thought that text coding is to be dealt with by the end, print function for example. That I just need to specify the coding for the compiler to use, since Windows doesent use ASCII in win32 apps, I guess C compiler must convert the char I typed to ASCII from whatever the type is that windows sends to the C editor. And the last thing is, what if I want to use for example 25 Byte integer for some high math operations? C has no specify-yourself datatype. Yes, I know that this would be difficult since all the math operations would need to be changed, becouse CPU can not add 25 Bytes numbers together. But is there a way to do it? Or is there some math library for it? What if I want to compute Pi to 1000000000000000 digits? :) I know my question is pretty long, but I just wanted to explain my thoughts the best I can in English, since its not my native language it is difficult. And I believe there is simple answer to my question(s), something I missed that explains everything. I read lot about text coding, C tutorials, but nothing about his. Thank you for your time.

  • C# Button Text Unicode characters.

    - by Fossaw
    C# doesn't want to put Unicode characters on buttons. If I put \u2129 in the Text attribute of the button, the button displays the \u2129, not the Unicode character, (example - I chose 2129 because I could see it in the font currently active on the machine). I saw this question before, link text, but the question isn't really answered, just got around. I am working on applications which are going all over the world, and don't want to install all the fonts, more then "don't want", there are that many that I doubt the machine I am working on has sufficient disk space. Our overseas sales agents supply the Unicode character "numbers". Is there another way forward with this? As an aside, (curiosity), why does it not work?

  • How should I handle incomplete packet buffers?

    - by Benjamin Manns
    I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

  • Convert Decimal to ASCII

    - by Dan Snyder
    I'm having difficulty using reinterpret_cast. Before I show you my code I'll let you know what I'm trying to do. I'm trying to get a filename from a vector full of data being used by a MIPS I processor I designed. Basically what I do is compile a binary from a test program for my processor, dump all the hex's from the binary into a vector in my c++ program, convert all of those hex's to decimal integers and store them in a DataMemory vector which is the data memory unit for my processor. I also have instruction memory. So When my processor runs a SYSCALL instruction such as "Open File" my C++ operating system emulator receives a pointer to the beginning of the filename in my data memory. So keep in mind that data memory is full of ints, strings, globals, locals, all sorts of stuff. When I'm told where the filename starts I do the following: Convert the whole decimal integer element that is being pointed to to its ASCII character representation, and then search from left to right to see if the string terminates, if not then just load each character consecutively into a "filename" string. Do this until termination of the string in memory and then store filename in a table. My difficulty is generating filename from my memory. Here is an example of what I'm trying to do: C++ Syntax (Toggle Plain Text) 1.Index Vector NewVector ASCII filename 2.0 240faef0 128123792 'abc7' 'a' 3.0 240faef0 128123792 'abc7' 'ab' 4.0 240faef0 128123792 'abc7' 'abc' 5.0 240faef0 128123792 'abc7' 'abc7' 6.1 1234567a 243225 'k2s0' 'abc7k' 7.1 1234567a 243225 'k2s0' 'abc7k2' 8.1 1234567a 243225 'k2s0' 'abc7k2s' 9. //EXIT LOOP// 10.1 1234567a 243225 'k2s0' 'abc7k2s' Index Vector NewVector ASCII filename 0 240faef0 128123792 'abc7' 'a' 0 240faef0 128123792 'abc7' 'ab' 0 240faef0 128123792 'abc7' 'abc' 0 240faef0 128123792 'abc7' 'abc7' 1 1234567a 243225 'k2s0' 'abc7k' 1 1234567a 243225 'k2s0' 'abc7k2' 1 1234567a 243225 'k2s0' 'abc7k2s' //EXIT LOOP// 1 1234567a 243225 'k2s0' 'abc7k2s' Here is the code that I've written so far to get filename (I'm just applying this to element 1000 of my DataMemory vector to test functionality. 1000 is arbitrary.): C++ Syntax (Toggle Plain Text) 1.int i = 0; 2.int step = 1000;//top->a0; 3.string filename; 4.char *temp = reinterpret_cast<char*>( DataMemory[1000] );//convert to char 5.cout << "a0:" << top->a0 << endl;//pointer supplied 6.cout << "Data:" << DataMemory[top->a0] << endl;//my vector at pointed to location 7.cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing 8.cout << "Characters:" << &temp << endl;//my temporary char array 9. 10.while(&temp[i]!=0) 11.{ 12. filename+=temp[i];//add most recent non-terminated character to string 13. i++; 14. if(i==4)//when 4 chatacters have been added.. 15. { 16. i=0; 17. step+=1;//restart loop at the next element in DataMemory 18. temp = reinterpret_cast<char*>( DataMemory[step] ); 19. } 20. } 21. cout << "Filename:" << filename << endl; int i = 0; int step = 1000;//top-a0; string filename; char *temp = reinterpret_cast( DataMemory[1000] );//convert to char cout << "a0:" << top-a0 << endl;//pointer supplied cout << "Data:" << DataMemory[top-a0] << endl;//my vector at pointed to location cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing cout << "Characters:" << &temp << endl;//my temporary char array while(&temp[i]!=0) { filename+=temp[i];//add most recent non-terminated character to string i++; if(i==3)//when 4 chatacters have been added.. { i=0; step+=1;//restart loop at the next element in DataMemory temp = reinterpret_cast( DataMemory[step] ); } } cout << "Filename:" << filename << endl; So the issue is that when I do the conversion of my decimal element to a char array I assume that 8 hex #'s will give me 4 characters. Why isn't this this case? Here is my output: C++ Syntax (Toggle Plain Text) 1.a0:0 2.Data:0 3.Data(1000):4428576 4.Characters:0x7fff5fbff128 5.Segmentation fault

  • Emailing HTML from within an iPhone app is stopping at special characters

    - by user141146
    Hi, I have an iPhone app that will let users email some pre-determined text as HTML. I'm having a problem in that if the text contains special characters within the text (e.g., ampersand &, , <), the NSString variable that I use for sending the body of the email gets truncated at the special character. I'm not sure how to fix this (I tried using the method stringByAddingPercentEscapesUsingEncoding…but this hasn't fixed the problems). Thoughts on what I'm doing wrong / how to fix it? Here is sample code showing what I'm trying to do Thanks!!! - (void)send_an_email:(id)sender { NSString *subject_string = [NSString stringWithFormat:@"Summary of %@", commercial_name]; NSString *body_string = [NSString stringWithFormat:@"%@<br /><br />", [self.dl email_message]]; // email_message returns the body of text that should be shipped as html. If email_message contains special characters, the text truncates at the special character NSString *full_string = [NSString stringWithFormat:@"mailto:?to=&subject=%@&body=%@", [subject_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [body_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [[UIApplication sharedApplication] openURL:[[NSURL alloc] initWithString:full_string]]; }

  • Axis2 issue with comment in WSDL

    - by Sirs
    I'm using an Axis2 client to access an external Webservice, whose WSDL starts with the following content: <?xml version="1.0" encoding="UTF-8"?><!--Created by TIBCO WSDL--><wsdl:definitions xmlns:wsdl=... My call to sendReceive crashes with the following error: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'C' (code 67) in prolog; expected '<' The 'C' is the first character on the comment in the WSDL. Without that comment everything works fine, but as far as my knowledge of basic XML dictates that comment is correct. My question would be: Is this a bug in Axis2 or is the accessed WSDL malformed? Is there any way to prevent Axis2 from crashing under these circumstances?

  • When is ¦ not equal to ¦?

    - by Trey Jackson
    Background. I'm working with netlists, and in general, people specify different hierarchies by using /. However, it's not illegal to actually use a / as a part of an instance name. For example, X1/X2/X3/X4 might refer to instance X4 inside another instance named X1/X2/X3. Or it might refer an instance named X3/X4 inside an instance named X2 inside an instance named X1. Got it? There's really no "regular" character that cannot be used as a part of an instance name, so you resort to a non-printable one, or ... perhaps one outside of the standard 0..127 ASCII chars. I thought I'd try (decimal) 166, because for me it shows up as the pipe: ¦. So... I've got some C++ code which constructs the path name using ¦ as the hierarchical separator, so the path above looks like X1¦X2/X3¦X4. Now the GUI is written in Tcl/Tk, and to properly translate this into human readable terms I need to do something like the following: set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 set humanreadable [join [split $path ¦] /] Basically, replace the ¦ with / (I could also accomplish this with [string map]). Now, the problem is, the ¦ in the string I get from C++ doesn't match the ¦ I can create in Tcl. i.e. This fails: set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 string match $path [format X1%cX2/X3%cX4 166 166] Visually, the two strings look identical, but string match fails. I even tried using scan to see if I'd mixed up the bit values. But set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 set path2 [format X1%cX2/X3%cX4 166 166] for {set i 0} {$i < [string length $path]} {incr i} { set p [string range $path $i $i] set p2 [string range $path2 $i $i] scan %c $p c scan %c $p2 c2 puts [list $p $c :::: $p2 $c2 equal? [string equal $c $c2]] } Produces output which looks like everything should match, except the [string equal] fails for the ¦ characters with a print line: ¦ 166 :::: ¦ 166 equal? 0 For what it's worth, the character in C++ is defined as: const char SEPARATOR = 166; Any ideas why a character outside the regular ASCII range would fail like this? When I changed the separator to (decimal) 28 (^\), things worked fine. I just don't want to get bit by a similar problem on a different platform. (I'm currently using Redhat Linux).

  • Regex to validate initials

    - by iar
    I'm looking for a regex to validate initials. The only format I want it to allow is: (a capital followed by a period), and that one or more times Valid examples: A. A.B. A.B.C. Invalid examples: a. a A A B A B C AB ABC Using The Regulator and some websites I have found the following regex, but it only allows exactly one upper (or lower!) case character followed by a period: ^[A-Z][/.]$ Basically I only need to know how to force upper case characters, and how I can repeat the validation to allow more the one occurence of an upper case character followed by a period.

  • Java String Replace and null characters

    - by praspa
    Testing out someone elses code (of course it was ...) , I noticed a few JSP pages printing funky non-ascii characters. Taking a dip into the source I found this tidbit. // remove any periods from first name e.g. Mr. John --> Mr John firstName = firstName.trim().replace('.','\0'); Does replacing a character in a String with a null character even work in Java? I know that '\0' will terminate a c-string. Would this be the culprit to the funky characters? Thanks PR

  • Delete Range of Data From Text File With PHP

    - by Evan Byrne
    I want to delete a range of data from a text file using PHP. Let's assume the file contains the following: Hello, World! I want to delete everything from character 2 to character 7. The actual file I need to do this with is very large, so I don't want to have to read the large file in order to delete just a small, given range of data. The data contained within the given range is not known, so str_replace or preg_replace solutions wouldn't work anyways. Thanks!

  • MySQL storing negative and positive decimals

    - by Shishant
    Hello, I want to be able to store -11.99 and +11.99 kind of values in mysql db I am thinking of decimals instead of varchar. But reading mysql site I found out that its incompatible with older versions of mysql As a result of the change from string to numeric format for DECIMAL storage, DECIMAL columns no longer store a leading + or - character or leading 0 digits. Before MySQL 5.0.3, if you inserted +0003.1 into a DECIMAL(5,1) column, it was stored as +0003.1. As of MySQL 5.0.3, it is stored as 3.1. For negative numbers, a literal - character is no longer stored. Applications that rely on the older behavior must be modified to account for this change. So what should be the data type, If I have to give up varchar and make it compatible with older versions too?

  • Replacing a colour/colours in a movieclip with different colours?

    - by Oli
    I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.
