  • How to organize a programming course?

    - by Bogdan Gavril
    I've been given the task to train our manual testers to become developers in test (write test automation!). some have basic programing knowledge (either dabbling in PHP or reading stuff) and some who have no experience. Note that I do have teaching experience, but with real students, not employees, and one concern is that they will not put extra hours except the 20% management gave them for the transition. Language to be taught and used: C# We have 8 hours per week to do this and should decide if they will make it in 2 months. I am thinking of a combined approach: use a manual such as Head First C# (although I'm not happy with the labs, they're mostly games and I don't want to add UI complexities) have them read from the manual do labs with them, solving more and more difficult problems and explain the theoretical stuff as well have them do a bigger project towards the end Some questions: do you have a better suggestion as far as manuals go? do you have a better aproach? Focus less on labs? what kind of assesments should I use and how often? should I let them do a bigger project (bank system or small game) and how much time should I invest in that? ideeas on labs? other resources ? Any other tips would be most welcomed! Thanks!

  • Introducing Deep Fried Devcast

    - by Matt Christian
    I've been working on a new podcast for the game development community called the Deep Fried Devcast.  Currently we are in pre-production but should have some episodes up in the near future.  Here is a quick FAQ about the show: What is the Deep Fried Devcast? The Deep Fried Devcast is a bi-weekly show all about game development.  The show will feature developer interviews, a focus on the technical aspects of game development (programming, technical design), the business of team game development (time management, project management), and other areas focused around the actual development of games. Wait, no game design?  No game discussions?! Calm down, calm down.  Although the focus of the podcast is on the technical aspects of game dev, there will be episodes and content focused on all areas of the gaming industry, including discussion on design, story, recent game releases, games we've been playing, etc...  Anything could show up in the Deep Fried Devcast and nothing is off limits. How can I help? We're always looking for new content ideas, emails, and anything you want to send us (within some kind of reason!).  You can even be a guest host if you want!  Email us at: deepfrieddevcast [AT] gmail [DOT] com Where's the podcast?! We're still recording it!  Don't worry, it will be up soon.  Keep an eye on www.deepfrieddevcast.com for the latest updates (that will be up soon too!).

  • What is a legal way to use music from registered authors in a game?

    - by mm24
    I have recently asked a question about music in games like Guitar Hero. I have found that that in Europe (at least) if I do want to use a track composed by a musician member of a royalty collecting society I need to pay a flat fee to the society and not only to the member. So a "one-to-one" agreement is not valid and the society can come up to me and ask me for money for each download. Even if for FREE! This is a fee sheet list of the UK agency: for fee, see "Permanent download services" It is about 1,200 GBP for less than 22,000 copies and they DON'T specify anything more and they said me on the phone that I need to wait and see how many downloads I get before knowing the price. This is kind of crazy as If I give away the App for free I will have to PAY 1,200 GBP!! I am shocked and I feel very bad. One agency suggested me to use a fake name of the artist, but in this way is not fair to my collaborators as what they hope is that the App gets lots of downloads and in this way that other people will get to know about them and hopefully commission them more work. The other solution is to work only with non registered musicians. The question here to you is: Has anyone found a legal way to use music from registered authors in a game?

  • Oracle Delivers Special Recognition for Specialized Partners

    - by michaela.seika(at)oracle.com
    Since announcing Oracle PartnerNetwork Specialized (OPN Specialized) in October 2009, Oracle has been focused on building a program that first enables solution providers to become highly skilled Oracle partners who deliver value to customers and that then recognizes and rewards their achievements in a meaningful way. Today the company unveiled new benefits reserved for partners who have achieved one or more of the over 50 specializations currently available. The benefits demonstrate Oracle's commitment to showcase these valued partners to three key audiences: customers, other partners, and Oracle employees.With today's launch of www.oracle.com/specialized Oracle has taken what IDC believes is a first of its kind approach to putting top partners front and center with customers and prospects. While most vendors offer a business partner finder tool on their website none has gone as far as Oracle with the creation of this new site dedicated to the promotion of Specialized Partners. The tag lines - "Recognized by Oracle, Preferred by Customers" and "Specialized. Recognized. Preferred." gets right to the point - these are the solution providers with which customers should choose to engage. The contents of the page offer multiple proof points to justify the marketing phrases.One of the benefits Oracle offers its Specialized Partners is video creation and placement. While Oracle works with partners to create informal or "guerilla" videos which often are placed on YouTube to generate awareness and buzz, the company also produces professional videos for its partners. The greatest value the partner receives from this benefit isn't the non-trivial production costs that Oracle covers but instead the prominent exposure Oracle gives the finished product. Partner videos are featured on www.oracle.com/specialized, used as part of monthly OPN Specialized Partners monthly webcasts, placed on a customer facing website, the Oracle Media Network, which includes several partner sites such as PartnerCast. A solution provider gains a great deal of credibility when they can send a prospect to an Oracle website where they are featured. Read the full article here.

  • Data binding in web UI frameworks, what's the deal?

    - by c-smile
    I believe that most of modern Web frameworks that pretend to be MVC ones also has a notion of data binding in one form or another. Examples: AngularJS, EmberJS, KnockoutJS, etc. I am assuming that "data binding" is a declarative definition (oxymoron, no?) of live link between data (a.k.a. model) and its representation (a.k.a. view). With some transformers in between (a.k.a. controllers). I understand why declarativeness is kind of appealing but also understand that as usual it comes with the price. In particular: 1. Live binding is quite heavy, either with dirty watch (high CPU consumption) or with Object.observe() (high memory consumption with high CPU load in some scenarios). 2. There is a "frame" part in the framework word, means there are some boundaries/limits that can be hard to overcome if you need slightly more than it was designed for. Quite usual time split: 90% of features are made in 10% of project time. But 10% rest take 90% of project time. I suspect (a.k.a. educated guess) that those MVC things are not helping to implement more functionality in less time... If so their usage motivation is not quite clear. As an example: last week wanted to find virtual list idea/solution. Found one in vanilla JavaScript that is 120 LOC. Implementation of the same but in AngualrJS is about 420 LOC. Most of the code there seems like a fight with the framework itself... So is my question: what benefits that MVC stuff or data binding give us? Is it just a buzzword popular among project managers or they give us something useful. If later one then what exactly?

  • Why do programmers write applications and then make them free?

    - by Ken
    As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubical. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

  • checking for collision detection

    - by bill
    I am trying to create a game where you have a player and you can move right,left, and jump. kind of like mario but its not a side scroller. also i want to use 2d array to make a tile map. my big problem is that i dont understand how to check for collision. i spend about 2 week thinking about this and i came up with 2 solution but they both have problems. let say my map is: 0 = sky 1 = player 2 = ground 00000 10002 22022 Solution 1: move the '1'(player) and update the map less say player wants to move right, then x+=grid[x+1][y] this make the collision easy bc you can just check if if(grid[x][y+1] == 2){ //player is standing on top of ground } problem with this when u hit right key player will move (x*Titlewidth) to right. and as you can see the animation wont look smooth. Solution 2: move player and dont update map player_x += 2 this will make the animation more smoother bc i am just moving 2 pixels. problem1: i cant update map bc if player some times will be middle of int(2d array). but thats ok sinces its not a side scroller so updating the map is not a big deal. problem2: only way to check for collision is to use java intersection method. but then player have to be atleast 1 or 2 pixel in ground in order to check for collision. and as you can see that wont look good too. plz note this is my first collision game in java. so plz try to explain alot otherwise i wont understand it.

  • Google local search rankings is it possible without the use of citations

    - by bybe
    I have a client that is wanting a website design for his self-run business... Basically he is a self employed plumber so his home address is not visitable by the public, however the problem here is that he does not want his home address visible on the internet at all for one reason or another. I have informed him the benefits of having his address visible for such reasons as trust by customers as well as the benefits via Google's local search algorithms (Citations - Visible Address Details) on various directories including Google Maps, and Google Places. But he is clear that he does not want his address online and wants SEO + Web Design without any citations. Now, I care about my reputation in my local area and do not like do half-cut jobs, If I do SEO I want them to be the best they can otherwise word of mouth that customer could say to someone else after my services they are no where to be seen, (I know you can't keep them all happy but none the less). This is kinda new for me since Google introduced local rankings and something I've never had to do... So my question is fairly simple and hope that people who reply have some kind of experience in attempting ranking websites locally without citations.. Is it even possible to rank a local website with Google's local algorithms without the use of citations (address information)?

  • How to protect your real time online shooter from potential bots

    - by Zaky German
    I'm looking to create a multiplayer top down shooter. While i've read about different topics, i can see them i've got some real challenges ahead, but i'm all up for it. One thing i can't understand is how am i supposed to be protecting the game from people who try to create bots? What i mean is, as far as i understand, it's impossible to protect the network traffic in a way that players won't be able to create programs that listen to what's going on and understand it. So what worries me is that people can create bots that listen to the current location of rival players, and send communication that mimic as if the player is shooting in the exact "perfect" location to win that match. So what kind of techniques are used to protect real time games from such bots? Also i'd like to mention that i've tried searching for discussions (as this sounds like something many people struggle with), but couldn't find anything about it specifically, only as a part of broader questions about networking in real time games. If i should have looked harder feel free to put me in my place :) Thanks alot!

  • SAP or Navision? Career Path

    - by codebased
    This could be tricky to ask; I may or may not ask this question here but I thought to give it a try. I've been in Software Industry since 2002 and now it has been a time that I'm at Senior level where I normally code, lead and define the architect; giving technical solutions to the management is one of my asset that I've earned during my services. Now it is the time to define the road map for the future, $$$. I am not in favor of Project Management roles. I've been thinking of going through the ERP and my current company does provide me an option to go for Navision/ Microsoft Dynamics. They are currently on 4.0 but they are planning to move for 2009 and also to build one of their own plug-in. Indeed the option is good because Microsoft is trying to accomplish the market for Dynamics products. However, they have less success in Australia. Now, Another option is with SAP where person can go with 200 K $ a year. Where as I'd doubt that if the same kind of growth, financial, is available for Microsoft geek. What is your opinion on Navision or SAP? If I try to completely move to SAP it could be bit challenging as market will consider me a fresher. However the return is quite good. Where in case of Microsoft, I think technology changes so fast that there is a less chance to grow in, within, the same experience; in other word, if any new framework comes in .net then market look for that person who knows this new framework and not .net But in case of SAP, where the base remain same and chances are to grab more money from the market. What would you do if you were me? In stackoverflow - Navision questions are 20+ where in SAP 200+///?? :-)

  • Creating a retro-style palette swapping effect in OpenGL

    - by Zack The Human
    I'm working on a Megaman-like game where I need to change the color of certain pixels at runtime. For reference: in Megaman when you change your selected weapon then main character's palette changes to reflect the selected weapon. Not all of the sprite's colors change, only certain ones do. This kind of effect was common and quite easy to do on the NES since the programmer had access to the palette and the logical mapping between pixels and palette indices. On modern hardware, though, this is a bit more challenging because the concept of palettes is not the same. All of my textures are 32-bit and do not use palettes. There are two ways I know of to achieve the effect I want, but I'm curious if there are better ways to achieve this effect easily. The two options I know of are: Use a shader and write some GLSL to perform the "palette swapping" behavior. If shaders are not available (say, because the graphics card doesn't support them) then it is possible to clone the "original" textures and generate different versions with the color changes pre-applied. Ideally I would like to use a shader since it seems straightforward and requires little additional work opposed to the duplicated-texture method. I worry that duplicating textures just to change a color in them is wasting VRAM -- should I not worry about that?

  • bluetooth headset can connect, but not visible in pulse audio

    - by Kim Marivoet
    I have a plantronics bluetooth headset, and until yesterday I could use it without any problem. However, today it suddenly stopped working (maybe related to the last software update I did). I can still connect/disconnect my headset, but it doesn't show up in pulse audio anymore. I read through various posts that describes kind of the same problem, but none of the suggested solutions worked. I get following error in the syslog: Oct 13 16:49:57 desktop bluetoothd[1040]: Endpoint registered: sender=:1.34 path=/MediaEndpoint/HFPAG Oct 13 16:49:57 desktop bluetoothd[1040]: Endpoint registered: sender=:1.34 path=/MediaEndpoint/A2DPSource Oct 13 16:49:57 desktop bluetoothd[1040]: Endpoint registered: sender=:1.34 path=/MediaEndpoint/A2DPSink Oct 13 16:50:09 desktop kernel: [ 17.340943] input: 48:C1:AC:08:FE:8F as /devices/virtual/input/input14 Oct 13 16:50:09 desktop bluetoothd[1040]: /org/bluez/1040/hci0/dev_48_C1_AC_08_FE_8F/fd0: fd(36) ready Oct 13 16:50:09 desktop rtkit-daemon[1894]: Successfully made thread 2213 of process 1892 (n/a) owned by '1000' RT at priority 5.

  • Combining Code Review with Trust Metrics

    - by DragonFax
    I don't get the chance to partake of it at work. But I love the idea of code review. Especially of online open source code review like Gerrit Code Review. I love what Trust Metrics have done for forums and collective intelligences sites on the internet like stackexchange, reddit, and wikipedia. Would it be possible to combine the two and come up with an open source project management system. Something that ends up being mostly community driven. Perhaps a kind of wikipedia of code for a project. Where submitters become popular/trusted by having lots of patches reviewed favoriably by others, and accepted into the trunk. And popular/trusted submitters get their patchs accepted faster/easier. I'm looking for some opinions on the idea, or perhaps pointers to where its been done before, if thats the case. This might leave the lead maintiner little more to do than: wrangle the direction of the project by fast-tracking or vetoing specific patches. settling disputes when the CI tests break, or fixing it himself. Is design by community worse than design by committee?

  • Design pattern for client/server sessions?

    - by nonot1
    Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.

  • Network Issues only on one network with a Broadcom BCM4312

    - by Ryan McClure
    My Ubuntu 11.10 laptop is having network connection issues...only on one network. I have a BCM4312 card and I'm using the proprietary driver. Whenever I connect to a network over wireless connection, I have no trouble except for one network. In my dorm, if I try to connect to the wireless network, it stays connected from anywhere to 30 seconds to 30 minutes before it will still be "connected" according to the indicator but there is no incoming/outgoing internet connection. This only happens in this building. Other networks with the same name at other buildings on my campus have no issue whatsoever. I took it to the tech department here and they keep claiming it's my laptop; but, if I can connect to other networks with absolutely no issues, why can't my laptop connect here? So, here's my question: Is it my laptop, or is it the network? As a side note, no one else that I know has issues on this network but one; she's running Windows 7 and I forget what kind of laptop it is. One of the people in my hall runs Ubuntu 12.04 and has no problem with the wireless. What do you all think of this?

  • What is Cloud Computing?

    - by joelvarty
    This is a question that we discuss quite often at Edentity.  It’s one of those things, kind of like “web services” where the terminology has been thrown around by a ton of people and means a lot of different things. Here’s my favorite diagram so far, which is a visual breakdown of the material presented here by NIST, visualized by the folks at Cloud Security Alliance.     What I like about this diagram is that is shows several different ways that we can differentiate our definitions of cloud computing, from the essential characteristics, or which “Broad Network Access" and “On-Demand Self-Service” (which often are used on their own to define cloud computing) are but a couple of things that help make something “cloud”. The most important section from my point of view is the middle one – the Service Models.  This represents the different ways that cloud computing can be exposed from the ground up.  It can be an Infrastructure, a Platform or a piece of Software that an end user interacts with. This is the future, folks. more late - joel

  • How to get multiple open-source projects to use a standard way of doing something.

    - by Marco
    Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

  • Should a programmer "think" for the client?

    - by P.Brian.Mackey
    I have gotten to the point where I hate requirements gathering. Customer's are too vague for their own good. In an agile environment, where we can show the client a piece of work to completion it's not too bad as we can make small regular corrections/updates to functionality. In a "waterfall" type in environment (requirements first, nearly complete product next) things can get ugly. This kind of environment has led me to constantly question requirements. E.G. Customer wants "automatically convert input to the number 1" (referring to a Qty in an order). But what they don't think about is that "input" could be a simple type-o. An "x" in a textbox could be a "woops" not I want 1 of those "toothpaste" products. But, there's so much in the air with requirements that I could stand and correct for hours on end smashing out what they want. This just isn't healthy. Working for a corporation, I could try to adjust the culture to fit the agile model that would help us (no small job, above my pay grade). Or, sweep ugly details under the rug and hope for the best. Maybe my customer is trying to get too close to the code? How does one handle the problem of "thinking for the client" without pissing them off with too many questions?

  • JEE frameworks, a road map to learn? and should I learn them?

    - by vibhor
    Background Information I have been into programming since past 1 years professionally, my day to day work includes writing BIRT reports, designing and validating forms using JEE (struts/spring, hibernate). I don't have a comp Sci 4 year degree (Electronics), so I have very Limited experience in comp Sci. Question JEE frameworks (struts1/2, spring, hibernate etc) are hot nowadays, however java world have a tendency of building A4j, B4J... mayway4J kind of stuff (and I am tired of it). AFAIK, frameworks are nothing but bunch of XML config files and hundreds of classes built to cram (by developer). And sooner then later a new framework come into picture that says I am the best among all. So My Question is - 1.What will you do to learn a framework (many frameworks) considering that it can be obsolete till you'll be master in it (Learning frameworks can take significant amount of time)? 2.Considering early into your career, will you give a damn that how well someone knows framework (knowing frame work is important but still..) and why/how should I learn a framework knowing I have to (un)learn it in order to learn other one (plenty of of 4Js....)? I am just trying to get a big picture, that, if you're in place of me, what would be your learning/cramming strategy (Road map)? I am not intended to start a holy war between A versus B, (frameworks are more or less essential).

  • How can I convince my boss to invest into the developer environment?

    - by user95291
    Our boss said that developers should have fewer mistakes so the company would have money for displays, servers etc. An always mentioned example is a late firing of an underperforming colleague whose salary would have covered some of these expenses. On the other hand it happened a few times that it took a few days to free up some disk space on our servers since we can't get any more disk. The cost of mandays was definitely higher than the cost of a new HDD. Another example is that we use 14-15" notebooks for development and most of the developers get external displays after they spent one year at the company. The price of a 22-24" display is just a small fraction of a developers annual salary. Devs say that they like the company because of other reasons (high quality code, interesting projects etc.) but this kind of issues not just simply time-consuming but also demotivate them. In the point of view of the developers it seems that the boss always can find an issue in the past which they could have been done better so it's pointless to work better to get for a second display/HDD/whatever. How can I convince my boss to invest more into development environment? Is it possible to break this endless loop?

  • Learning from jQuery - Solid fundament for experienced jQuery developers

    Frankly speaking, I had to sleep a night over before typing this review. And even now it is not an easy, straight-forward task to write this recension. I'm not sure whether I'm the right kind of audience this title is actually addressed to. It clearly states that this book is for web developers which are very familiar with jQuery library but would like to extend their knowledge to vanilla JavaScript. Not being part of this particular group it felt strange to go through the various chapters after all. This title is clearly addressed to experienced jQuery users and developers especially while looking for improvements in performance and better ways of optimisations. Sometimes just to simplify the existing jQuery code in order to avoid the heavy load of the complete jQuery library and sometimes for the better understanding of JavaScript and its syntax. Callum's style of writing is clear and the numerous code samples used to emphasize the various techniques are good ones and easy to understand. Quite interestingly, it put a light smile on my face when I compared his sample code of sending an AJAX request to some code in one of my own blog articles I wrote back in 2006 (in German language). JavaScript is clearly a mature language and certain requirements are simply done this way. And Callum explains the nuts and bolts of JavaScript very well. Personally, I gained most out of this book from chapter 5 - JavaScript Conventions. The paragraphs and code snippets on Optimizations and Common Antipatterns gave me a better understanding on various aspects of JavaScript development, and I definitely have to revise a couple of code fragments I have written in the past. Overall the book provides solid information on JavaScript for jQuery developers and is worth the money spent. Just be sure that you're part of the targeted audience.

  • Authentication system brainstorm

    - by gansbrest
    Hi. We got multiple small websites (microsites) and one main high traffic one with big users base. Right now the requirement is to build authentication system which should allow users to loign with the same identity across the network. All website are running on different domains, powered by Drupal 6 CMS and have separate databases (so sharing tables with prefix is not an option + it creates a huge mess in the db). Here is the set of core requirements I came up with: Users should be able to login with the same credentials to all sites within the network User’s data sharing between Main site (storage) and all micro sites within the network Data synchronization across the network when user changes the data (update email or password for example) The login/registration process should be seamless and consistent Register on any of the sites across the network and use that identity to login later on. In the future there might be a need to add openid authentication options. Basically we are looking at something similar stackexchange does, but not sure if they have central users base on not. I was thinking about custom solution which will include 2 parts (modules), one will be stored on the Main site for users data storing and responding to requests from clients. Second part (module) will be placed on each microsite, which is going to send requests to the Master. Some kind of client - server setup. One of the complications I see right away is #3. Data Synhcronization across the network. I just don't want to reinvent the wheel and maybe some work is already done in this direction. Looking forward to your ideas on how to approach this project. EDIT: We use MySQL database

  • Creating a newspaper that effects the game's economy?

    - by zardon
    I am writing a game in Objective C/cocos2d where a newspaper is a central part of what controls or rather effects the game's world economy as well as what a city might do (such as increase X, reduce Y) The newspaper is a bit like a "Chance card" in Monopoly, it has an effect on something. My question is, what is the best way to do write a newspaper that has both a random and specific effect within the game. Would the best strategy be to write out all the things a newspaper can affect, a PLIST of headlines (with placeholders). I think Tiny Tower uses a PLIST of events and it randomly picks an event, but I'm not sure how it actually parses it because certain events do different things. But then how do I parse all the scenarios that a newspaper can deliver? A big switch statement seems very long and complicated to do. I am wondering if there is a simpler way to handle this kind of thing. Related to this is that there might be no news that day and I'm not sure what the newspaper should display, should it just display the last headline? So, in summary. 1) A newspaper generates a headline, it affects different things, such as the world economy, prices, how city reacts 2) I need the newspaper to generate headlines (although there may be days when there are no headlines at all), but I am not sure how to parse it without using a big-ass switch statement. Thanks in advance.

  • How can I perform 2D side-scroller collision checks in a tile-based map?

    - by bill
    I am trying to create a game where you have a player that can move horizontally and jump. It's kind of like Mario but it isn't a side scroller. I'm using a 2D array to implement a tile map. My problem is that I don't understand how to check for collisions using this implementation. After spending about two weeks thinking about it, I've got two possible solutions, but both of them have some problems. Let's say that my map is defined by the following tiles: 0 = sky 1 = player 2 = ground The data for the map itself might look like: 00000 10002 22022 For solution 1, I'd move the player (the 1) a complete tile and update the map directly. This make the collision easy because you can check if the player is touching the ground simply by looking at the tile directly below the player: // x and y are the tile coordinates of the player. The tile origin is the upper-left. if (grid[x][y+1] == 2){ // The player is standing on top of a ground tile. } The problem with this approach is that the player moves in discrete tile steps, so the animation isn't smooth. For solution 2, I thought about moving the player via pixel coordinates and not updating the tile map. This will make the animation much smoother because I have a smaller movement unit per frame. However, this means I can't really accurately store the player in the tile map because sometimes he would logically be between two tiles. But the bigger problem here is that I think the only way to check for collision is to use Java's intersection method, which means the player would need to be at least a single pixel "into" the ground to register collision, and that won't look good. How can I solve this problem?
