  • Per Pixel Collision Detection

    - by CJ Cohorst
    Just a quick question, I have this collision detection code: public bool PerPixelCollision(Player player, Game1 dog) { Matrix atob = player.Transform * Matrix.Invert(dog.Transform); Vector2 stepX = Vector2.TransformNormal(Vector2.UnitX, atob); Vector2 stepY = Vector2.TransformNormal(Vector2.UnitY, atob); Vector2 iBPos = Vector2.Transform(Vector2.Zero, atob); for(int deltax = 0; deltax < player.playerTexture.Width; deltax++) { Vector2 bpos = iBPos; for (int deltay = 0; deltay < player.playerTexture.Height; deltay++) { int bx = (int)bpos.X; int by = (int)bpos.Y; if (bx >= 0 && bx < dog.dogTexture.Width && by >= 0 && by < dog.dogTexture.Height) { if (player.TextureData[deltax + deltay * player.playerTexture.Width].A > 150 && dog.TextureData[bx + by * dog.Texture.Width].A > 150) { return true; } } bpos += stepY; } iBPos += stepX; } return false; } What I want to know is where to put in the code where something happens. For example, I want to put in player.playerPosition.X -= 200 just as a test, but I don't know where to put it. I tried putting it under the return true and above it, but under it, it said unreachable code, and above it nothing happened. I also tried putting it by bpos += stepY; but that didn't work either. Where do I put the code? Any help is appreciated. Thanks in advance!

  • Developer Compensation System

    - by Graviton
    Joel wrote excellent articles on developer compensation system used at Fogcreek. As a team lead and business owner, I would like to device a system that would work best for my team. And here's the catch: I have no experience in managing a team before, and I don't know what works and what doesn't. So I would like to get as many references as I can on this matter. Is there other developer compensation systems that you find is working for you and your company?

  • Web Developer or Web Designer

    - by user1702801
    I have built 10+ straightforward websites using the Symfony framework and Wordpress. Does this mean I am a web developer or a web designer? I set the sites up in Symfony and wrote the CSS/Javascript/HTML. I had to write themes for Wordpress and move some code about. What experience do I need to to be a web developer and not a designer? What experience distinguishes me from a designer that knows HTML and jQuery?

  • The best Drupal and JavaScript developer?

    - by hakanito
    I've read a lot of JS articles and books by Nicholas Zakas and Addy Osmani, in my opinion evangelists in the field. But I am also a Drupal developer, and these guys are not. Many of the techniques they're talking about such as AMD and RequireJS are great, but it's hard to know how to integrate them when it comes to Drupal (and do it right, ofc). So my question is if there are any recognized developer/s out there with strong JavaScript AND Drupal experience?

  • Algorithmically generating neon layers on pixel grid

    - by user190929
    In an attempt at a screensaver I am making, I am a fan of neo-like graphics, which, of course, look great against a black background. As I understand it, neon, graphically speaking, is essentially a gradient of a color, brightest in the center, and gets darker proceeding outward. Although, more accurate is similar, but separating it into tubes and glow. The tubes are mostly white, while the glow is where most of the color is seen. Well... the tubes could also be a light variant of the color, you could say. The glow is darker. Anyhow, my question is, how could you generate such things given an initial pattern of pixels that would be the tubes? For example, let's say I want to make a neon 'H'. I, via the libraries, can attain the rectangles of pixels which represent it, but I want to make it look neonized. How could I algorithmically achieve such an effect given a base tube shape and base color? EDIT: ok, I mistated that. Got a bit distracted. My purpose for this was similar to a neon effect, but not. Sorry about that. What I am looking for is something like this: Start with a pattern of pixels: [!][!][!][!][!][!][!][!] [!][!][O][!][!][!][!][!] [!][!][O][O][!][!][!][!] [!][!][!][!][O][!][!][!] [!][!][!][!][!][!][!][!] How to I find the U pixels? [!][E][E][E][!][!][!][!] [!][E][O][E][E][!][!][!] [!][E][O][O][E][E][!][!] [!][E][E][E][O][E][!][!] [!][!][!][E][E][E][!][!] Sorry if that looks bad.

  • Should I be an algorithm developer, or java web frameworks type developer?

    - by Derek
    So - as I see it, there are really two kinds of developers. Those that do frameworks, web services, pretty-making front ends, etc etc. Then there are developers that write the algorithms that solve the problem. That is, unless the problem is "display this raw data in some meaningful way." In that case, the framework/web developer guy might be doing both jobs. So my basic problem is this. I have been an algorithms kind of software developer for a few years now. I double majored in Math and Computer science, and I have a master's in systems engineering. I have never done any web-dev work, with the exception of a couple minor jobs, and some hobby level stuff. I have been job interviewing lately, and this is what happens: Job is listed as "programmer- 5 years of experience with the following: C/C++, Java,Perl, Ruby, ant, blah blah blah" Recruiter calls me, says they want me to come in for interview In the interview, find out they have some webservices development, blah blah blah When asked in the interview, talk about my experience doing algorithms, optimization, blah blah..but very willing to learn new languages, frameworks, etc Get a call back saying "we didn't think you were a fit for the job you interviewed wtih, but our algorithm team got wind of you and wants to bring you on" This has happened to me a couple times now - see a vague-ish job description looking for a "programmer" Go in, find out they are doing some sort of web-based tool, maybe with some hardcore algorithms running in the background. interview with people for the web-based tool, but get an offer from the algorithms people. So the question is - which job is the better job? I basically just want to get a wide berth of experience at this level of my career, but are algorithm developers so much in demand? Even more so than all these supposed hot in demand web developer guys? Will I be ok in the long run if I go into the niche of math based algorithm development, and just little to no, or hobby level web-dev experience? I basically just don't want to pigeon hole myself this early. My salary is already starting to get pretty high - and I can see a company later on saying "we really need a web developer, but we'll hire this 50k/year college guy, instead of this 100k/year experience algorithm guy" Cliffs notes: I have been doing algorithm development. I consider myself to be a "good programmer." I would have no problem picking up web technologies and those sorts of frameworks. During job interviews, I keep getting "we think you've got a good skillset - talk to our algorithm team" instead of wanting me to learn new skills on the job to do their web services or whhatever other new technology they are doing. Edit: Whenever I am talking about algorithm development here - I am talking about the code that produces the answer. Typically I think of more math-based algorithms: solving a financial problem, solving a finite element method, image processing, etc

  • 2D Pixel/sprite game in unity? [on hold]

    - by acidzombie24
    Hi I'm an absolute newbie in unity. In the past I was told unity is terrible for 2d games so I look away after looking at it for a few days. I don't remember if this was right before unity4 came out or after. I hear unity is fairly good at 2d now. I tried googling for tutorials but I'm doing it wrong. I could not find a good tetris or tic tac toe tutorial. What assets/tutorials do I want for a 2D game? Side question is what tutorials are good if I want to make a fire emblem/advance wars type game (HUD heavy grid base game)

  • TypeScript or JavaScript for noob web developer [closed]

    - by Phil Murray
    Following the recent release by Microsoft of TypeScript I was wondering if this is something that should be considered for a experienced WinForm and XAML developer looking to get into more web development. From reviewing a number of sites and videos online it appears that the type system for TypeScript makes more sense to me as a thick client developer than the dynamic type system in Javascript. I understand that Typescript compiles down to JavaScript but it appears that the learning curve is shallower due to the current tooling provided by Microsoft. What are your thoughts?

  • The Developer's Conference Florianópolis, Brazil

    - by Tori Wieldt
    by guest blogger Yara Senger With over 2900 developers in person and another 2000 online, The Developer's Conference (TDC) in Florianópolis, Brazil, reminds us that Java is BIG in Brazil. The conference included 20 different tracks, and Java was the most popular track. Java was also a big part of the talks in the IoT, Cloud and BigData tracks. Here's my overview (in Brazilian Portguese): Several JUGs were involved in TDC Florianópolis, serving as track leads, speakers and all-around heros, including SouJava SouJava Campinas GUJava Santa Catarina JUG Vale JUG Maringá Java Bahia GOJava (Goinia) JUG Rio do Sul RS Jug (Rio Grande do Sul) and I thank them for their support and commitment. It is a vibrant and fun community! We saw that the IoT space is maturing rapidly. There are already some related to embedded in the region.  Java Evangelist Bruno Borges and Marco Antonio Maciel gave a view popular talk "Java: Tweet for Beer!" They demonstrated how to make a beer tap controlled by Java and connected to the Internet, using a visual application JavaFX with Java SE 8, running on a Rasperry Pi. Of course, they had to test the application quite throughly.   We Brazilians are training the next generation of Java developers. TDC4Kids was as big success. We made a tour with the kids in all booths and almost everybody talked about Java. Java in government managment (Betha), Java on the 2048  (Oracle), Java on the popcorn machine and Java training (Globalcode & V.Office) and of course: Java & Minecraft! OTN's Pablo Ciccarello was there to support the community.  He did several video interviews with JUG leaders and speakers (mine included). You can watch more videos on his TDC Florianópolis playlist.  Thank you, Oracle and OTN for all your support. We interacted with thousands of Java developers at The Developer's Conference Florianópolis. If you want to join us, we are planning two more conferences this year: The Developer's Conference São Paulo, July  The Developer's Conference Porto Alegre, October

  • Pixel alignment algorithm

    - by user42325
    I have a set of square blocks, I want to draw them in a window. I am sure the coordinates calculation is correct. But on the screen, some squares' edge overlap with other, some are not. I remember the problem is caused by accuracy of pixels. I remember there's a specific topic related to this kind of problem in 2D image rendering. But I don't remember what exactly it is, and how to solve it. Look at this screenshot. Each block should have a fixed width margin. But in the image, the vertical white line have different width.Though, the horizontal lines looks fine.
