• Navigation Controller with Tab Bar only on first view

  - by dinoc

  I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.

• Python: Removing particular character (u"\u2610") from string

  - by duhaime

  I have been wrestling with decoding and encoding in Python, and I can't quite figure out how to resolve my problem. I am looping over xml text files (sample) that are apparently coded in utf-8, using Beautiful Soup to parse each file, then looking to see if any sentence in the file contains one or more words from two different list of words. Because the xml files are from the eighteenth century, I need to retain the em dashes that are in the xml. The code below does this just fine, but it also retains a pesky box character that I wish to remove. I believe the box character is this character. (You can find an example of the character I wish to remove in line 3682 of the sample file above. On this webpage, the character looks like an 'or' pipe, but when I read the xml file in Komodo, it looks like a box. When I try to copy and paste the box into a search engine, it looks like an 'or' pipe. When I print to console, though, the character looks like an empty box.) To sum up, the code below runs without errors, but it prints the empty box character that I would like to remove. for work in glob.glob(pathtofiles): openfile = open(work) readfile = openfile.read() stringfile = str(readfile) decodefile = stringfile.decode('utf-8', 'strict') #is this the dodgy line? soup = BeautifulSoup(decodefile) textwithtags = soup.findAll('text') textwithtagsasstring = str(textwithtags) #this method strips everything between anglebrackets as it should textwithouttags = stripTags(textwithtagsasstring) #clean text nonewlines = textwithouttags.replace("\n", " ") noextrawhitespace = re.sub(' +',' ', nonewlines) print noextrawhitespace #the boxes appear I tried to remove the boxes by using noboxes = noextrawhitespace.replace(u"\u2610", "") But Python threw an error flag: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 280: ordinal not in range(128) Does anyone know how I can remove the boxes from the xml files? I would be grateful for any help others can offer.

• How to implement friction in a physics engine based on "Advanced Character Physics"

  - by paldepind

  I have implemented a physics engine based on the concepts in the classic text Advanced Character Physics by Thomas Jakobsen. Friction is only discussed very briefly in the article and Jakobsen himself notes how "other and better friction models than this could and should be implemented." Generally how could one implement a believable friction model on top of the concepts from the mentioned article? And how could the found friction be translated into rotation on a circle? I do not want this question to be about my specific implementation but about how to combine Jakobsens ideas with a great friction system more generally. But here is a live demo showing the current state of my engine which does not handle friction in any way: http://jsfiddle.net/Z7ECB/embedded/result/ Below is a picture showing and example on how collision detection could work in an engine based in the paper. In the Verlet integration the current and previous position is always stored. Based on these a new position is calculated. In every frame I calculate the distance between the circles and the lines. If this distance is less than a circles radius a collision has occurred and the circle is projected perpendicular out of the offending line according to the size of the overlap (offset on the picture). Velocity is implicit due to Verlet integration so changing position also changes the velocity. What I need to do know is to somehow determine the amount of friction on the circle and move it backwards parallel to the line in order to reduce its speed.

• 2D character controller in unity (trying to get old-school platformers back)

  - by Notbad

  This days I'm trying to create a 2D character controller with unity (using phisics). I'm fairly new to physic engines and it is really hard to get the control feel I'm looking for. I would be really happy if anyone could suggest solution for a problem I'm finding: This is my FixedUpdate right now: public void FixedUpdate() { Vector3 v=new Vector3(0,-10000*Time.fixedDeltaTime,0); _body.AddForce(v); v.y=0; if(state(MovementState.Left)) { v.x=-_walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=-_maxWalkSpeed; } else if(state(MovementState.Right)) { v.x= _walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=_maxWalkSpeed; } _body.velocity=v; Debug.Log("Velocity: "+_body.velocity); } I'm trying here to just move the rigid body applying a gravity and a linear force for left and right. I have setup a physic material that makes no bouncing and 0 friction when moving and 1 friction with stand still. The main problem is that I have colliders with slopes and the velocity changes from going up (slower) , going down the slope (faster) and walk on a straight collider (normal). How could this be fixed? As you see I'm applying allways same velocity for x axis. For the player I have it setup with a sphere at feet position that is the rigidbody I'm applying forces to. Any other tip that could make my life easier with this are welcomed :). P.D. While coming home I have noticed I could solve this applying a constant force parallel to the surface the player is walking, but don't know if it is best method.

• A Kingdom To Conquer: Character Sketches

  - by George Clingerman

  Still not 100% sold on my title so it remains a working title for now, but here’s a series of character sketches I’ve done for a turn based strategy game I’m playing at making. I’ve been sketching these on various pieces of paper throughout the last two weeks and just finished the last of them today (my plan was for 16 different types of units and well, now I have them, so I consider that done!).                    Pretty rough sketches for now, but I’m pretty happy with the art style overall. I was wrestling for quite a while just HOW I wanted the game to look and then I finally stumbled across Art Baltazar and I was like, THAT’S IT! There’s a few characters I need to re-do a bit more, I feel they’re a bit TOO much like some of the characters that inspired them but I’m happy that the ideas are finally sketched out. I’ve also been playing a bit in InkScape working on making these guys digital. A pretty new experience for me since I’m not used to working with vector images but I think I’ll get the hang of it. Here’s the Knight all vectorized. Now if I could just start making some progress on the actual game itself…

• Character progression through leveling, skills or items?

  - by Anton

  I'm working on a design for an RPG game, and I'm having some doubts about the skill and level system. I'm going for a more casual, explorative gaming experience and so thought about lowering the game complexity by simplifying character progression. But I'm having trouble deciding between the following: Progression through leveling, no complex skill progression, leveling increases base stats. Progression through skills, no leveling or base stat changes, skills progress through usage. Progression through items, more focus on stat-changing items, items confer skills, no leveling. However, I'm uncertain what the effects on gameplay might be in the end. So, my question is this: What would be the effects of choosing one of the above alternatives over the others? (Particularly with regards to the style and feel of the gameplay) My take on it is that the first sacrifices more frequent rewards and customization in favor of a simpler gameplay; the second sacrifices explicit customization and player control in favor of more frequent rewards and a somewhat simpler gameplay; while the third sacrifices inventory simplicity and a player metric in favor of player control, customization and progression simplicity. Addendum: I'm not really limiting myself to the above three, they are just the ones I liked most and am primarily interested in.

• Blending animations for more character movements

  - by Noob Saibot

  I am making a hack n slash 3rd person game. And I want the character movements to be more dynamic not like fighting games where you have a moves list. I want to animate tons of different animations and have them "Tween" between each other? Because I want the controls to not be keyboard mouse. I want it to be all keyboard. that way you have up to 10 inputs (All your fingers) to blend and morph animations to create more fluid movements. In the end this will almost be similar to characters typing a phrase or string of keys rather than move forward mouse look click to melee. My question is. Has anyone done this before and would someone go about trying to tween lets say one for key on the keyboard excluding Tab, Caps, R+Shift, L+Shift, Enter, R+Ctrl, L+Ctrl, L+Alt, R+Alt, Windows Key, and Menu. So thats all the numbers, letters and punctuation keys. Thats 46 keys gives me a combination of 46P1 = 5502622159812088949850305428800254892961651752960000000000L (used Python) and with a minimum entry value of 2 keypresses shortening to half. This is not humanly possible to create so many inique animations in one lifetime. But I'm guessing there is a reason this hasn't been done already. Or if I just used 10 basic keys. Maybe ASDF SPACE (RIGHT HAND) 456+0 (LEFT HAND KEYPAD) it would give me 3,628,800 posible unique animations.

• Efficient mapping layout in 2D side-scroller, and collisions between character and the world

  - by Jack

  I haven't touched Visual Studio for a couple months now, but I was playing a game from the '90s toady and had an epiphany: I was looking for something what i didn't need, and I wasn't using what I knew correctly. One of those realizations was collision, so let me tell you a bit about my project that I was working on. The project's graphics looks like Mario or Dangerous Dave, etc., you get the idea - old-school pixels. So anyway I remember trying to think of something else than AABB for character form, but I couldn't think of anything. Perhaps I could get a suggestion for this? Another thing is the world - I don't want it to be just linear world, I want mountains, etc.. My idea is to use triangles, and no idea yet what to do if I want just part of the cube, say 3/4 or 2/4 or whatever. Hard-coding such things seems inefficient. P.S. I am not looking at the precision level offered by Box2D. Actually I remember trying to implement it at first, but I failed as my understanding of C++ wasn't advanced enough, as it'll be mentioned below. P.P.S. I am programming in C++, and I haven't done it for a couple months now. I have no means of testing it either, as my PC is broken down, and this one can barely run games from late '90s, not to speak about a compiler or a program with inefficient resource management... I am also not an expert (obviously), I don't even know if I can consider myself an average programmer. In short, I am simply curious about my thoughts and my past experience when programming the game. I may come back to it when my PC is fixed, I'm already filling a note about these things.

• Character movement on a 2D tile map

  - by Chris Morris

  I'm working at making a HTML5 game. Top down, closest thing I can equate it to is the gameboy zeldas, but open world and no rooms. What I have so far is a procedurally generated map in a multi dimensional array. And a starting position on the map. Along with this I have an array of movable and non movable tile ID's. I also have a class for my player and have him being rendered out in the center of the starting tile. My problem however is getting the movement sorted out for the player. I want to be able to have the character free move around the map (pixel by pixel essentially) ontop of this 2D generated world. Ideally this would allow the user to move around the walk able area of the canvas. this is simple enough for me to do, but I am having problems now moving the world. If the user is 20% from the edge of the screen i want the world to start panning in the direction the player is heading. But I'm rather lacking in ideas of how to do this. I've looked around for some tutorials, but am coming up blank on ideas of how to generate the playable area (zoomed in) and to then move this generated area under the player when they reach near the end of the screen. My current idea was to generate a certain amount of tiles full size to fill the screen and place the player i the middle. Then when the user approaches the edge of the screen start generating the tiles offset by the distance moved and the direction. I can kind of see this working but I really have no idea if this is the best or easiest to code of methods for generating the world. sorry for the lack of code but I'm still just in the theory stages of working this all out.

• Importing tab delimited file into array in Visual Basic 2013 [migrated]

  - by JaceG

  I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

• 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. }

• 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?

• 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

• jQuery: tabs where the tab/content can be linked to

  - by Ricardo Zea

  My issue is simple. I have already implemented a tab system, and I'd probably spend more time implementing another one with the solution I need, than giving a shot at adapting the code I have, and learn something while asking :) My problem is that the tabs can't be linked to, I need to be able to link to a tab from another website or page, and have that tab get selected upon page load. ie: I have three tabs showing different products, by default tab 1 is active/selected when the page loads. From the home page I want to link to tab 2 but I can't link to tab 2 because it doesn't get selected. Not sure if that makes sense. Tabs: <ul> <li><a href="products.php">Product 1</a></li> <li><a href="products.php">Product 2</a></li> <li><a href="products.php">Product 3</a></li> </ul> <div class="tab_container"> <div id="tab1" class="tab_content">Product 1 info...</div> <div id="tab2" class="tab_content">Product 2 info...</div> <div id="tab3" class="tab_content">Product 3 info...</div> </div> my jQuery: $(document).ready(function() { //Default Action $(".tab_content").hide(); $("ul.tabs li:first").addClass("active").show(); $(".tab_content:first").show(); //On Click Event $("ul.tabs li").click(function() { $("ul.tabs li").removeClass("active"); $(this).addClass("active"); $(".tab_content").hide(); var activeTab = $(this).find("a").attr("href"); $(activeTab).fadeIn(); return false; }); }); Is there a way this code can be adapted to be able to link to any tab from anywhere and have that tab get selected when the page loads? Thanks in advance.

  I am writing my first chrome extension, and I want to pass a variable to the currently opened tab and manipulate the DOM with it. My extension has a button, and when clicked, is executing this code: chrome.tabs.getSelected(null, function(tab) { chrome.tabs.executeScript(tab.id, { file: 'tabscript.js' }); }); This works fine, but I see no way to pass a variable to tabscript.js so it can be used on the opened tab.

I have tried placing this code in viewWillAppear and other application lifecycle methods but no luck.

The documentation seems to suggest using a t:var, like this: let t:guitablabel="foo" But it doesn't do anything. Is there any way to give each different tab a different name?
