• JS / HTML 5 Compatablity issue on iOS 6

  - by Dhaval

  I'm using HTML 5 to play video and there are some content before the video so I'm using flexroll to scroll that whole window. I'm checking it on iPad, now problem is that in iOS 5 its working fine but when I update to iOS 6 then screen is not scrolling only video is scroll up and down, content is as it is in the position. I can't understand what is the exact problem. Is that js compatibility issue or HTML 5 video compatibility issue. Can anyone please help me to figure out, your help will really be appreciated.

• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• Any pre-rolled System.IO abstraction libraries out there for Unit Testing?

  - by Binary Worrier

  To test methods that use the file system we need to basically put System.IO behind a set of interfaces that we can then mock, I do this with a DiskIO class and interface. As my DiskIO code gets larger (and the grumblings from the we're unconvinced about this TDD thing crowd here in work get louder), I went looking for a comprehensive open source library that already does this and found . . . nothing. I may be looking in the wrong place or have approached this problem in completely the wrong way. I can't be the only idiot in this position, do these libraries exist, if so where are they? Any you've used and would recommend? Thanks P.S. I'm happy with my current approach i.e. starting with what we need, and adding only when the need arises. Unfortunately the we're unconvinced about this TDD thing crowd remain unconvinced, and think that I can't be right.

• 2-D Lighting Theory

  - by Richard

  I am writing a rogue-like 'zombie' management game. The game map will be similar to Prison Architect. A top-down 50 X 50 grid. I want to implemented a day night cycle and during the night I would like the player to be able to position lights. I would like to be able to lighten and dark to whole map to display the day and night cycle. Then lights would be a circle of light blocked by game entities such as walls, players, trees etc. How would I achieve and what is the standard way of achieving this?

• How do I calculate the motion of 2 massive bodies in space?

  - by 1224

  I'm writing code simulating the 2-dimensional motion of two massive bodies with gravitational fields. The bodies' masses are known and I have a gravitational force equation. I know from that force I can get a differential equation for coordinates. I know that I once I solve this equation I will get the coordinates. I will need to make up some initial position and some initial velocity. I'd like to end up with a numeric solver for the ordinal differential equation for coordinates to get the formulas that I can write in code. Could someone break down how from laws and initial conditions we get to the formulas that calculate x and y at time t?

• Adding gesture recognizer (or dragging) to CCSprite

  - by user339946

  I'm trying to allow a CCSprite to be dragged across the screen. I've succeeded so far by doing it on a Layer level (from this tutorial). However, this only allows ONE sprite to be dragged at a time as the method implementation can only identify a single sprite to move at a time. I'd like to be able to perhaps add a gesture recognizer or somehow implement ccTouchesBegan/Moved in my own little CCSprite subclass. However, from what I understand, you can't just add gesture recognizers to CCSprites. ccTouchMoved are also not available on CCSprites?? Really confused as to how to implement touches on Cocos2D. What is the easiest way to add some position translation code to a CCSprite so it can be dragged around? Thanks!

• Should i expect real world questions from interviewing agency ? [closed]

  - by KPO

  I started coding almost a year ago. By "coding" I mean HTML(5), CSS(3), and only few times I implemented some AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I feel confident in HTML5/CSS3 subject area and somewhat ok with javascript. Will agency expect from me to write some code during the interview? I do have a live website as an example which contains snapshots of past projects which were sent to them. I am little nervous, so any tips or recommendations are welcome.

• Do I need a Point and a Vector object? Or just using a Vector object to represent a Point is ok?

  - by JCM

  Structuring the components of an engine that I am developing along with a friend (learning purposes), I came to this doubt. Initially we had a Point constructor, like the following: var Point = function( x, y ) { this.x = x; this.y = y; }; But them we started to add some Vector math to it, and them decided to rename it to Vector2d. But now, some methods are a bit confusing (at least in my opinion), such as the following, which is used to make a line: //before the renaming of Point to Vector2, the parameters were startingPoint and endingPoint Geometry.Line = function( startingVector, endingVector ) { //... }; I should make a specific constructor for the Point object, or there are no problems in defining a point as a vector? I know a vector have magnitude and direction, but I see so many people using a vector to just represent the position of an object.

• How can I calculate the angle between two 2D vectors?

  - by Error 454

  I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating two vectors, v, the facing direction of ship 1, and w, the vector pointing from the position of ship 1 to ship 2. I am then calculating the angle between these two vectors using the formula arccos((v · w) / (|v| · |w|)) The problem I'm having is that arccos only returns values between 0° and 180°. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

• What's a good model for continuous manager <-> programmer feedback?

  - by MebAlone

  Is it important for managers to give devs regular feedback on how they're doing and vice versa? I say vice versa because I consider employees to be responsible to their manager, and managers to be responsible to their employees. Everyone seems to think this is a good idea but in practice I rarely see it happen because so many shops are "agile" now and that usually means a daily standup plus a weekly kickoff, etc. So one-on-ones just don't happen. In my last position I had my first one-on-one w/ my manager 6 months after I'd been w/ the company. It turned out there was lots of misunderstanding, misalignment and confusion built up and snowballed. Not really surprising when there's no direct personal communication for that long.

• Rendering only a part of text FTGL, OpenGL

  - by Mosquito

  I'm using FTGL library to render text in my C++ project. I can easily render text by using: CFontManager::Instance().renderWrappedText(font, lineLength, position, text); Unfortunately there is a situation in which this Button which displays text, is partly hidden because of resizing container in which it is situated. I'm able without any problem to draw Button's background to fit the container, but I've got a problem with doing the same with a text. Is it possible to somehow draw only text for given width and the rest just ignore? This is a screen which presents my problem: As you can see, the Button "Click here" is being drawn properly, but I can't do the same with "Click here" text.

• What's the best route to getting started in moble app development?

  - by Rob Z

  As per the question title, I'm interested in starting up a new side project and I'm currently looking at doing a bit of mobile development as said project. I'm actually in a bit of a good position right now as I have a blank slate in front of me (i.e. not locked into a phone already) but on the same token, I also don't want to invest too much money into hardware and the like since this will likely not be a money making venture. As such, which platform provides the best flexibility in terms of experimentation and learning opportunities? Likewise, what are some useful resources to assist in the process?

• Engine Start and Stop Show Abnormal Behaviour

  - by Siddharth

  In my game, when I pause the game using mEngine.stop() it works perfectly but when I press resume button that has code mEngine.start() it provide some movement to the physics body. So the created body does not stand at its desire position after the resuming the game. That fault I have found in other game developed by other developer also. So please provide some guidance for it. I also tried with mScene.onUpdate(0) and mScene.onUpdate(1) but I does not able to found anything new from it.

• Dual 7950, freezes during startup

  - by Hiro

  I have two identical video cards right now. Xubuntu will boot up no problem if I only have one card installed. If I install the 2nd card it will just hang midway thru the loading screen. Regardless of which card I use and which position on the motherboard, it will freeze if I have both installed. I've tried installing the proprietary drivers, both fglrx and fglrx-updates, still freezes in the same spot. Uninstalled those and went back to the default ones. The only way I can get a terminal is by booting into failsafe mode. Booting using 13.10 i386 on a USB stick gives me some errors related to what I think is the 2nd video card: [drm:r600_ring_test] ERROR radeon: ring 1 test failed (scratch(0x850C)=0xCAFEDEAD) [drm:r600_dma_ring_test] ERROR radeon: ring 3 test failed (0x02FFFF6B) radeon 0000:0200.2 disabling GPU acceleration"

• How do I build a matrix to translate one set of points to another?

  - by dotminic

  I've got 3 points in space that define a triangle. I've also got a vertex buffer made up of three vertices, that also represent a triangle that I will refer to as a "model". How can I can I find the matrix M that will transform vertex in my buffer to those 3 points in space ? For example, let's say my three points A, B, C are at locations: A.x = 10, A.y = 16, A.z = 8 B.x = 12, B.y = 11, B.z = 1 C.x = 19, C.y = 12, C.z = 3 given these coordinates how can I build a matrix that will translate and rotate my model such that both triangles have the exact same world space ? That is, I want the first vertex in my triangle model to have the same coordinates as A, the second to have the same coordinates as B, and same goes for C. nb: I'm using instanced rendering so I can't just give each vertex the same position as my 3 points. I have a set of three points defining a triangle, and only three vertices in my vertex buffer.

• Looking for advice on B2B promotion [closed]

  - by IconicDigital

  Can anyone recommend affiliate networks that focus on B2B development. We are about to launch a UK job search engine that allows job boards to list their jobs on the engine. We have decided to keep the advertising in house, with the goal being of keeping the costs down. I was wondering if anyone could offer any advice on potential advertising routes that we could take. For example B2B affiliate networks, adwords etc. We are in the position of launching an empty site and ideally we would like to be attracting recruitment agencies or businesses to signup to either a free or paid account. They can then begin to populate the engine with job listings. An obvious choice so far would be to promote on networks like Linked In. Any ideas? Thanks

• World orientation in OpenGLES clarification

  - by Dev2rights

  I have a 3d tile map made up of individual billboards in OpenGLES. Each is a 2 triangles mesh and has a 3D Vector to determine its position and another defining its rotation from the origin at (0,0,0). Im trying to work out how to rotate the entire tile map around a point be that the origin or some arbitrary point in space. Im guessing i need to set up a Model Matrix instead for each tile. Then set up a world matrix for the world. Then on updating i would translate the world matrix and change the orientation and multiply it with each model matrix before rendering. Is this correct ?

• Sprite.js surface background

  - by user1086671

  I'm making a tile-based game using Sprite.js. It is not easy to redraw every tile each frame, so I tried to make a scrolling surface background. There is an example here http://batiste.dosimple.ch/sprite.js/tests/test_scrolling.html The example works, but it seems like ScrollingSurface.update is buggy or there is something I'm missing. What I tried to do is to draw 5x5 tiles and after 5 seconds draw another 5x5 tiles near the first ones. But it draws only the first ones. And surface.update() only updates the position of surface. Here is my code https://github.com/Sektoid/sprite.js/blob/master/tests/test_scrolling.html (You need also to set this.divider = 1.0 in scrolling.js to avoid drawing the same tiles 4 times.) There aren't any sprite.js-forums like with the other sprite- and game-engines have, so I'm asking here.
