  • In MMO game, how to handle user characters, who are offline?

    - by Deele
    In my medieval MMO game, players have their own character, that represents themselves inside game. Like a King. Players could have cities and armies, but King acts as main driving force. Then it comes to player, going offline/vacation/disconnect. How to deal with "offline King", to keep some sort of reality in game, without ruining everything for player. I have never liked unrealistic stuff in games, like appearing/dissapearing from thin air, like in WoW or other MMO RPG's, when it comes to connect/disconnect, like in Matrix movie, when you are disconnected, your "avatar" inside the system just vaninshes. Ok, if player char stays where it was left, other players who are online could kick his ass like offline player char was frozen? I see only one solution - give player char, while offline, some sort of AI, that controls char. Is there any other solutions? May be, some sort of legend/story, could make users only as inner-voice, leaving King just passively controlled by user, or other stuff... Please, help! I hope you understand my question.

  • Updating sprite location with controls

    - by iQue
    So ive got a character in a 2D game using surfaceView that I want to be able to move using a button(eventually a joystick), but my game crashes as soon as I try to move my sprite. This is my onTouch-method for my steering button: public void handleActionDown(int eventX, int eventY) { if (eventX >= (x - bitmap.getWidth() / 2) && (eventX <= (x + bitmap.getWidth()/2))) { if (eventY >= (y - bitmap.getHeight() / 2) && (y <= (y + bitmap.getHeight() / 2))) { setTouched(true); } else { setTouched(false); } } else { setTouched(false); } and if I try to put this in my update-method: public void update() { x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } the sprite moves on its own just fine, but as soon as I add: public void update() { if(steering.isTouched()){ x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } the game crashes. Does any1 know why this is or how to fix it? I cannot figure it out. Im using MotionEvent.ACTION_DOWN to check if the user if pressing the screen. }

  • Crash when trying to detect touch

    I have this Structure the elements of which that I need to write in a text file struct Stage3ADisplay { int nSlot; char *Item; char *Type; int nIndex; unsigned char attributesMD[17]; //the last character is \0 unsigned char contentsMD[17]; //only for regular files - //the last character is \0 }; buffer = malloc(sizeof(Stage3ADisplayVar[nIterator]->nSlot) + sizeof(Stage3ADisplayVar[nIterator]->Item) + sizeof(Stage3ADisplayVar[nIterator]->Type) + sizeof(Stage3ADisplayVar[nIterator]->nIndex) + sizeof(Stage3ADisplayVar[nIterator]->attributesMD) + sizeof(Stage3ADisplayVar[nIterator]->contentsMD) + 1); sprintf (buffer,"%d %s %s %d %x %x",Stage3ADisplayVar[nIterator]->nSlot, Stage3ADisplayVar[nIterator]->Item,Stage3ADisplayVar[nIterator]->Type,Stage3ADisplayVar[nIterator]->nIndex,Stage3ADisplayVar[nIterator]->attributesMD,Stage3ADisplayVar[nIterator]->contentsMD); How do I make sure the rows in the file are properly aligned. Thank you.

  • HP Color LaserJet 2605dn color alignment issue

    - by robertvt
    We have a HP Color LaserJet 2605dn at work that recently lost its mind. The red and blue colors are offset from where they should be and producing a rather trippy 3D look. I've performed a manual calibration through the menus and poked at just about everything I could find. These toner cartridges are not new (as you can see they're about 50% used) but only just recently started this problem. They were working great up until this error appeared. It happens on mac, pc, and via the printer menu printouts so I don't think it's a driver problem. The printer has been restarted and reset and is running the newest firmware. Anyone have any ideas? Here's a pic http://img16.imageshack.us/img16/9984/photoon20090914at1149.jpg

  • Windows 7 dual monitor setup: Wallpaper alignment

    - by Tomalak
    I have the following dual-screen set up on my Windows 7 PC: [2][1], that means my secondary monitor is on the right side of my primary monitor. Now I have a dual-screen wallpaper that should stretch across the monitors. I have set it to "Tile" mode. Problem: The wallpaper invariably starts at [1] (left edge of the image being on the left edge of [1]), and then continues on [2]. It basically splits the wrong way, producing a rather awkward look. How can I make the wallpaper appear correctly (i.e. left edge of the image being on the left edge of [2])?

  • Implementing a wheeled character controller

    - by Lazlo
    I'm trying to implement Boxycraft's character controller in XNA (with Farseer), as Bryan Dysmas did (minus the jumping part, yet). My current implementation seems to sometimes glitch in between two parallel planes, and fails to climb 45 degree slopes. (YouTube videos in links, plane glitch is subtle). How can I fix it? From the textual description, I seem to be doing it right. Here is my implementation (it seems like a huge wall of text, but it's easy to read. I wish I could simplify and isolate the problem more, but I can't): public Body TorsoBody { get; private set; } public PolygonShape TorsoShape { get; private set; } public Body LegsBody { get; private set; } public Shape LegsShape { get; private set; } public RevoluteJoint Hips { get; private set; } public FixedAngleJoint FixedAngleJoint { get; private set; } public AngleJoint AngleJoint { get; private set; } ... this.TorsoBody = BodyFactory.CreateRectangle(this.World, 1, 1.5f, 1); this.TorsoShape = new PolygonShape(1); this.TorsoShape.SetAsBox(0.5f, 0.75f); this.TorsoBody.CreateFixture(this.TorsoShape); this.TorsoBody.IsStatic = false; this.LegsBody = BodyFactory.CreateCircle(this.World, 0.5f, 1); this.LegsShape = new CircleShape(0.5f, 1); this.LegsBody.CreateFixture(this.LegsShape); this.LegsBody.Position -= 0.75f * Vector2.UnitY; this.LegsBody.IsStatic = false; this.Hips = JointFactory.CreateRevoluteJoint(this.TorsoBody, this.LegsBody, Vector2.Zero); this.Hips.MotorEnabled = true; this.AngleJoint = new AngleJoint(this.TorsoBody, this.LegsBody); this.FixedAngleJoint = new FixedAngleJoint(this.TorsoBody); this.Hips.MaxMotorTorque = float.PositiveInfinity; this.World.AddJoint(this.Hips); this.World.AddJoint(this.AngleJoint); this.World.AddJoint(this.FixedAngleJoint); ... public void Move(float m) // -1, 0, +1 { this.Hips.MotorSpeed = 0.5f * m; }

  • What's the UITableView index magnifying glass character?

    - by David Grant
    In Apple's iPhone apps (like Contacts), they have a nice magnifying glass icon at the top of the table view index. Since the table view index API is character-based, I assume that this magnifying glass is a Unicode character. So far I've resorted to placing a question mark character there, but that looks lame. Can anyone tell me what character the magnifying glass is?

  • Ab Initio - Formatting a number in Left alignment

    - by Veera
    I have a requirement in Ab Initio to format a number in left alignment. I shouldn't be using String conversion (as Strings are left aligned by default), as it might cause compatibility problems in the other end. For example, if my Field has 7 bytes length, and I'm getting only two digits as my input, then these two digits should go into the first two bytes of my field (left aligned), instead of the last two bytes. So, is there any in-built function in Ab Initio, that can format a number as left aligned?

  • What is the Null Character literal in TSQL?

    - by David in Dakota
    I am wondering what the literal for a Null character (e.g. '\0') is in TSQL. Note: not a NULL field value, but the null character (see link). I have a column with a mix of typical and a null character. I'm trying to replace the null character with a different value. I would have thought that the following would work but it is unsuccessfull: select REPLACE(field_with_nullchar, char(0), ',') from FOO where BAR = 20

  • Is there a list of language only character regions for UTF-8 somewhere?

    - by Brehtt
    I'm trying to analyze some UTF-8 encoded documents in a way that recognizes different language characters. For my approach to work I need to ignore non-language characters, such as control characters, mathematical symbols etc. Just trying to dissect the basic Latin section of the UTF standard has resulted in multiple regions, with characters like the division symbol being right in the middle of a range of valid Latin characters. Is there a list somewhere that identifies these regions? Or better yet, a Regex that defines the regions or something in C# that can identify the different characters?

  • How to correct character encoding in IE8 native json ?

    - by mike_t2e
    I am using json with unicode text, and having a problem with the IE8 native json implementation. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script> var stringified = JSON.stringify("?????? olé"); alert(stringified); </script> Using json2.js or FireFox native json, the alert() string is the same as in the original one. IE8 on the other hand returns Unicode values rather than the original text \u0e2a\u0e27\u0e31\u0e2a\u0e14\u0e35 ol\u00e9 . Is there an easy way to make IE behave like the others, or convert this string to how it should be ? And would you regard this as a bug in IE, I thought native json implementations were supposed to be drop-in identical replacements for json2.js ?

  • Japanese character stored in SQL Server DB using ASP page that assumed it as ISO-8859-1 encoding

    - by Vishal Seth
    We have a legacy ASP based product that allowed the UI and Data languages of user groups to be configured according to their locations. CodePage and CharSet in ASP pages collecting data was set accordingly. I've noticed few instances in the SQL Server DB where users posted Japanese characters in the ASP page that assumes the oncoming stream to be of ISO-8859-1/Western and as a result, the data in the SQL table has gobbled up. While upgrading the client to our new product, I want to back-convert those "garbage" Japanese (in some instances Chinese) characters back to their actual form. Can I create some utility ASP page that would go through such data values and "fix" the wrongly-encoded strings and store everything back as utf-8 strings? In any case, I don't want to affect my French/Spanish/English characters that might be there as well.

  • R: How to separate character output in a loop?

    - by John
    I'm blanking on the best way to paste a list of strings together to go into an SQL statement... I'm having trouble with the separator bar | printing at the beginning when I don't want it to: foo = "blah" paste_all_together = NULL for (n in 1:4) { paste_together = paste(foo ,sep = "") paste_all_together = paste(paste_all_together, paste_together, sep = "|") } > paste_all_together [1] "|blah|blah|blah|blah" I just want it to print out "blah|blah|blah|blah". Do I need a nested loop, or is there a better itterator in R for doing this? Or perhaps a better way to input SQL statements?

  • return first non repeating character in a string

    - by Amm Sokun
    I had to solve this question in which given a string, i had to return the first non repeating character present in the string. I solved it using hashtable and wrote a method which takes a constant reference to the string and returns the first non repeating character. However, when there is no non repeating character present in the string, i return -1 and in the main program i check as follows char c = firstNonRepeating( word ); if (static_cast<int> (c) == -1) cout<<"no non repeating character present\n"; else cout<<c<<endl; is that the correct way to return -1 when required character is not present?

  • Table character encoding - exception in application

    - by zgnilec
    I have a code: CREATE TABLE IF NOT EXISTS Person ( name varchar(24) ... ) CHARACTER SET utf8 COLLATE utf8_polish_ci; This works OK in my application, but I read if someone put in name field a string that contains character wchich code is greater than 127, database will use 2 bytes (or more) to store this character. So i think, i will change character set to utf16: CHARACTER SET utf16 COLLATE utf16_polish_ci; But now when I run my application, exception apears: KeyNotFoundException. It apears exactly at these instructions: MySqlCommand komenda = baza.Polaczenie.CreateCommand (); komenda.CommandText = zapytanie; MySqlDataReader dr = komenda.ExecuteReader (); // HERE, at execute reader method if (dr.Read ()) ... 1) Anyone had similar problem? 2) Any idea how to use always 2 bytes/char in database field?

  • How do I read UTF-8 characters via a pointer?

    - by Jen
    Suppose I have UTF-8 content stored in memory, how do I read the characters using a pointer? I presume I need to watch for the 8th bit indicating a multi-byte character, but how exactly do I turn the sequence into a valid Unicode character? Also, is wchar_t the proper type to store a single Unicode character? This is what I have in mind: wchar_t readNextChar (char** p) { char ch = *p++; if (ch & 128) { // This is a multi-byte character, what do I do now? // char chNext = *p++; // ... but how do I assemble the Unicode character? ... } ... }

  • finding character in string C language

    - by iSight
    Hi, I am searching a character at first occurence in string using the following code. But, it is taking some time when the character is too long or the character that i am searching is at far extend, which makes delay in other operations. How could i tackle with this problem. The code is below here. Note: attrPtr is a char* which holds a reference to a string containing '"' character at far extend. int position = 0; char qolon = '"';//character to search while (*(attrPtr + position++) != qolon); char* attrValue = NULL; attrValue = (char*)malloc(position * sizeof(char)); strncpy(attrValue, attrPtr, position-1);
