  • Building a Flash Platformer

    - by Jonathan O
    I am basically making a game where the whole game is run in the onEnterFrame method. This is causing a delay in my code that makes debugging and testing difficult. Should programming an entire platformer in this method be efficient enough for me to run hundreds of lines of code? Also, do variables in flash get updated immediately? Are there just lots of threads listening at the same time? Here is the code... stage.addEventListener(Event.ENTER_FRAME, onEnter); function onEnter(e:Event):void { //Jumping if (Yoshi.y > groundBaseLevel) { dy = 0; canJump = true; onGround = true; //This line is not updated in time } if (Key.isDown(Key.UP) && canJump) { dy = -10; canJump = false; onGround = false; //This line is not updated in time } if(!onGround) { dy += gravity; Yoshi.y += dy; } //limit screen boundaries //character movement if (! Yoshi.hitTestObject(Platform)) //no collision detected { if (Key.isDown(Key.RIGHT)) { speed += 4; speed *= friction; Yoshi.x = Yoshi.x + movementIncrement + speed; Yoshi.scaleX = 1; Yoshi.gotoAndStop('Walking'); } else if (Key.isDown(Key.LEFT)) { speed -= 4; speed *= friction; Yoshi.x = Yoshi.x - movementIncrement + speed; Yoshi.scaleX = -1; Yoshi.gotoAndStop('Walking'); } else { speed *= friction; Yoshi.x = Yoshi.x + speed; Yoshi.gotoAndStop('Still'); } } else //bounce back collision detected { if(Yoshi.hitTestPoint(Platform.x - Platform.width/2, Platform.y - Platform.height/2, false)) { trace('collision left'); Yoshi.x -=20; } if(Yoshi.hitTestPoint(Platform.x, Platform.y - Platform.height/2, false)) { trace('collision top'); onGround=true; //This update is not happening in time speed = 0; } } }

  • trying to convert rails 2.3.4 app to rails 3 but views not appearing

    - by kgrad
    I have a simple rails 2.3.4 application I am trying to get running with rails 3.0.0-beta2. I have the server running and all my links and navigation showing, however for some reason the content of my views is not displaying. When I navigate to Site/index the html in my index.html.erb in my site view is completely ignored. There are no errors in the server log. My template is rendered properly (where all the links and navigation are being created) within application.html.erb however all of my actual view files are being ignored. Has anyone experienced this? I am using old style routing with map.connect, could this be the issue? Does anyone have a tutorial on how to convert old routes to new ones? I couldn't figure it out. my current routes look like this: map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' map.root :controller => :site, :action => :index

  • Flash was "not designed to function across LANs". Any workarounds?

    - by Triynko
    See: http://helpx.adobe.com/flash/kb/problems-using-flash-authoring-across.html Issue When using Adobe Flash across a local area network (LAN) and networked drives/folders, you may experience any of the following problems:" Flash crashes while performing a test movie on FLA files located on a networked drive or folder. FLA files get corrupted when opening from or saving to networked drives or folder. Flash does not reflect changes in custom class after compiling. Flash, Flash Video Encoder, or Adobe Media Encodercrashes or corrupts Flash Video (FLV) files while encoding source located on networked drives or folder. Flash Video Encoder or Adobe Media Encoder crashes or corrupts FLV files where the output folder is a networked drive or folder. Published Flash Player (SWF) files and projectors are unable to load content located on networked drives or folder. More than one instance of a SWF or Projector on client machines cannot play back FLV files located on a networked drive or folder. Reason The Adobe Flash IDE, FLV Encoder, Adobe Media Encoderand Flash Player were not designed to function across LANs. Solution Use of Flash files across local networks is not supported in any context. Published content should access data through a web server. All file sources should be opened and saved on the local system. Using Flash in such a scenario for project collaboration or content deployment is highly discouraged and may corrupt your source files. If you need to work in a collaborative environment or store source files on a server, use the project panel and/or a third-party version control system. SERIOUSLY? I cannot work on files located on a mapped network drive? How did they mess that one up? Does the Flash IDE really open the source file and wipe it clean to do the saving, rather than saving a copy first then replacing it as an atomic file system operation? How hard would it be for them make a dummy temporary file for saving then issue a MOVE command? Any workarounds for this, like something that can make a network drive as stable as a local drive, like some kind of automatic local caching and synching?

  • Noob Rails ? about learning Rails

    - by user271916
    Hi All I have been programming for a while and for the past 3 or 4 months have been learning ruby. I am not an expert by any means but I believe I have the basics down. I decided to start learning RoR and bought the "Agile Web Development with Rails 3rd Edition" and have been dutifully going through the chapters one by one. Currently I am in chapter 8 and have had no problems so far. My question is I know I have learned several things so far and I know that I am starting to get a sense of the Rails framework I have this fear that I am just not learning as much as I should. Some things I get and understand the interconnections while I feel on other things I am just going through the motions and don't fully comprehend the total interconnectivity. Now, there is still a large amount of the book for me to complete. I guess I am just wondering if I complete this book what should I expect to be able to accomplish on my own and what should be my next steps. Thanks

  • How to customize flash message based on success or failure with Inherited Resources Rails plugin?

    - by wgpubs
    I'm using the inherited resources plugin in a 2.3.5 Rails application and was wondering how to change the flash[:notice] (or any other flash) based on the success OR failure in my create and update actions. So given the below, how do I add flash[:notice] = "All good" if success ... and flash[:notice] = "All bad" if failure?

  • Rails 3 Form For Custom Action

    - by Andrew
    I'm having trouble routing a form to a custom action in Rails 3. Here are my routes: resources :photos do resources :comments collection do get 'update_states' end member do put 'upload' end end Here's the form_for: form_for @photo, :remote => true, :url => { :action => upload_photo_path(@photo) }, :html => { :multipart => :true, :method => 'put' } do |f| And here's the error message: No route matches {:action=>"/photos/42/upload", :controller=>"photos"} ... this is especially frustrating because "photos/:id/upload" is exactly the correct action for this form. What am I missing? EDITS - Here are the original Photo-related routes: photo_comments GET /photos/:photo_id/comments(.:format) {:action=>"index", :controller=>"comments"} POST /photos/:photo_id/comments(.:format) {:action=>"create", :controller=>"comments"} new_photo_comment GET /photos/:photo_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} edit_photo_comment GET /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"} photo_comment GET /photos/:photo_id/comments/:id(.:format) {:action=>"show", :controller=>"comments"} PUT /photos/:photo_id/comments/:id(.:format) {:action=>"update", :controller=>"comments"} DELETE /photos/:photo_id/comments/:id(.:format) {:action=>"destroy", :controller=>"comments"} update_states_photos GET /photos/update_states(.:format) {:action=>"update_states", :controller=>"photos"} upload_photo PUT /photos/:id/upload(.:format) {:action=>"upload", :controller=>"photos"} photos GET /photos(.:format) {:action=>"index", :controller=>"photos"} POST /photos(.:format) {:action=>"create", :controller=>"photos"} new_photo GET /photos/new(.:format) {:action=>"new", :controller=>"photos"} edit_photo GET /photos/:id/edit(.:format) {:action=>"edit", :controller=>"photos"} photo GET /photos/:id(.:format) {:action=>"show", :controller=>"photos"} PUT /photos/:id(.:format) {:action=>"update", :controller=>"photos"} DELETE /photos/:id(.:format) {:action=>"destroy", :controller=>"photos"} Here are the relevant routes when I changed the route to match 'upload': photo_comments GET /photos/:photo_id/comments(.:format) {:action=>"index", :controller=>"comments"} POST /photos/:photo_id/comments(.:format) {:action=>"create", :controller=>"comments"} } new_photo_comment GET /photos/:photo_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} edit_photo_comment GET /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"} photo_comment GET /photos/:photo_id/comments/:id(.:format) {:action=>"show", :controller=>"comments"} PUT /photos/:photo_id/comments/:id(.:format) {:action=>"update", :controller=>"comments"} DELETE /photos/:photo_id/comments/:id(.:format) {:action=>"destroy", :controller=>"comments"} update_states_photos GET /photos/update_states(.:format) {:action=>"update_states", :controller=>"photos"} upload_photo /photos/:id/upload(.:format) {:action=>"upload", :controller=>"photos"} photos GET /photos(.:format) {:action=>"index", :controller=>"photos"} POST /photos(.:format) {:action=>"create", :controller=>"photos"} new_photo GET /photos/new(.:format) {:action=>"new", :controller=>"photos"} edit_photo GET /photos/:id/edit(.:format) {:action=>"edit", :controller=>"photos"} photo GET /photos/:id(.:format) {:action=>"show", :controller=>"photos"} PUT /photos/:id(.:format) {:action=>"update", :controller=>"photos"} DELETE /photos/:id(.:format) {:action=>"destroy", :controller=>"photos"} Unfortunately 'match' didn't work any better... -- EDIT -- Just to confirm another scenario here... with this in the routes: resources :photos do resources :comments collection do get 'update_states' end member do match 'upload' end end and this in the view: form_for @photo, :remote => true, :url => { :action => 'upload' }, :html => { :multipart => :true, :id => 'photo_upload' } do |f| I still get: No route matches {:action=>"upload", :controller=>"photos"}

  • Flash movies in inactive browser tabs pause or don't execute in real time

    - by ZenBlender
    I'm noticing some unexpected behavior. Some time in the last few months, a change in either Firefox, the Flash player, or both, has made it so that Flash movies that are in inactive browser tabs no longer execute in real time. They appear to still execute, but only in bursts, and not in a predictable way. This is a problem because I develop a Flash-based (Actionscript 2.0, Flash CS3) multiplayer game that maintains a network connection and allows players to chat, etc. Many of our players complain about Firefox crashing while playing the game. I have noticed it too, not too frequently, but it crashes several times a week. (Firefox crashes, I do not get a message from Flash player that indicates an infinite loop or problem in my code) My theory is that this new behavior is causing crashes when there is a lot of activity in my game, leading to lots of unhandled network traffic for my game getting buffered before Firefox/Flash will give it a chance to execute. Maybe this leads to a buffer overflow or missing packets, and as a result, something crashes. At times I will switch back to the tab that is running my game and discover a display bug, which looks as though Flash has simply failed to execute something that it was supposed to. I would assume this new behavior is on purpose, for example to prevent all the Flash-based advertisements in inactive tabs from executing and therefore killing performance. In a quick test on Chrome (5.0.342.9 beta), this "pausing" of Flash seems to be there as well, but somehow it seems much less of a problem. My users have only complained about Firefox crashing, not other browsers. My machine: Windows 7 x64 Firefox 3.6.3 Flash Player 10.1.50.426 My game: triplejack.com Any ideas? Ideally I'd like to disable this behavior for my Flash game so it can execute in real time even when in an inactive tab. Thanks for any help!

  • Can someone explain the true landscape of Rails vs PHP deployment, particularly within the context of Reseller-based web hosting (e.g., Hostgator)?

    - by rcd
    Currently, I have a reseller account with the company HostGator. I design websites, which up until now have occasionally been wrapped in Wordpress CMSs and the like (PHP applications). I then sell hosting (of the site I've designed) to the client, which is pretty simple, in that I can simply click a button and add a new shared hosting account/site with whatever settings I want. Furthermore, I then utilize WHMCS to automate billing and account management. It's a nice package and pretty simple. I pay something like $25 a month, and can sell a hundred accounts under this (because my clients bandwidth requirements are low). Now I am finding the need to develop more customized applications, including a minimalist CMS and several proprietary things. I soon anticipate developing these apps for clients as well. Thus, I've spent the past few months learning Rails, and it's coming along well now. The thing that has nagged at me all along, though, is the deployment issue. I can't wrap my brain around it. It seems like all of the popular options (Heroku, etc) have nice automation with git and are set up in the "Rails Way". I get that (sort of). But it's terribly expensive... a single dyno, a helper, and the cheapest database (which they say is mainly suitable for testing) that isn't limited to 5MB runs $51. This is for ONE app!!! Throw in a "production" DB and you're over $200. This is like... the same prices as getting a server somewhere, right? Meanwhile, going back to what I guess is a "traditional" hosting environment with Hostgator, their server only has Ruby 1.8.7 and Rails 2.3.5... No Rails 3. AND, no Passenger (not that I really understand the difference in CGI or mod_rails or whatever, but they say Passenger is the simplest). So I'm to understand that if I build an app in Rails 3, it won't run at all on this host? But damn, I already have these accounts under my reseller account there, all running static html and/or PHP stuff, right? So what now? How do I get all of this under one simple (and affordable) roof? Forgive my ignorance, but I just don't get it. Managing a VPS is cool and all, but entails learning server admin stuff and security... And it's expensive. I get that a shared and/or reseller "server-based" (forgive the terminology) may be inadequate for large-scale apps that use a lot of bandwidth... But what about for those of us who are building real (but small and low bandwidth) apps (with Rails) and who want to deploy them simply, cheaply, using the same conceptual approach as PHP? Even after learning all of this Ruby and Rails stuff for months, I'm questioning whether it's worth it when it comes to deployment. I want to build a small app, upload it to my home directory on a shared server account, and just make it run. Why should that be so hard? Am I just choosing the wrong language/framework? Forgive my ignorance in the subject; these questions are not rhetorical; just trying to learn here. So: 1) I'd appreciate if someone could give me a good rundown of how to understand deployment in Rails vs. PHP. 2) I'd appreciate if someone could address my issue with running a hosting/web business around reseller hosting (Hostgator) while also being able to host Rails apps. Can it be done? And how can a company like Hostgator completely ignore what's current in Rails/Ruby? Thanks.

  • Flash video has become jittery in Karmic

    - by creamcheese
    When I first installed Karmic, I must have installed a Flash player or else it came with Karmic. It worked fine and I have been running the Ubuntu updates whenever requested by the OS. However, now my Flash video is extremely jittery and the whole computer kinds of slows down whenever I try to play a Flash video file. I have no idea what type of Flash player is running or what is the best one to use. Would appreciate any recommendations. Thanks.

  • Multiple Rails apps on same subdomain?

    - by Derek
    I recently decided to try out Rails. When working with PHP, I simply had all of my PHP projects in the same directory. For example, I may have http://ubuntu/app1, http://ubuntu/app2, etc. I created a subdomain for Rails (http://ruby.ubuntu), installed Rails and Passenger and everything is working. However, I may be wrong, but it looks like I can only have one Rails app per subdomain? My VirtualHost is as follows: <VirtualHost *:80> ServerName ruby.ubuntu ServerAdmin webmaster@localhost DocumentRoot /var/www/ruby/blog/public <Directory /var/www/ruby/blog/public> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all RailsEnv development </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> All of my PHP and misc. files are stored in /var/www/main. I want to be able to store all of my Rails apps in /var/www/ruby. I tried changing DocumentRoot to /var/www/ruby, but I don't think it's as simple as that. When I browse to a Rails app's Welcome Aboard page and click on "About my application's environment," I get a 404 page, but when the DocumentRoot is set to the public directory, I get the expected result. I don't want to have to create a new subdomain every time I create a new project. Is there any way I can make it so I can store all of my apps in /var/www/ruby, and browsing to http://ruby.ubuntu will let me access all of my Rails apps there? That way if I want to create a new app, all I have to do is rails new app, no Apache .htaccess or VirtualHost configuration required.

  • Why use flash to as content headings? Why not?

    - by Itai
    A large number of sites lately which use Flash to replace what would be simple HTML headings (h1, h2, h3). Some of them do it consistently for every header. Why would you do this? What are the pros and cons of this? This seems strange to me and really inefficient, particularly since a page can have dozens of headers. I notice this because I use Flash Block (which temporarily disables Flash), so not everyone may have seen it. Just today I landed here with 4 flash headers. I've seen dozens of such use of Flash this week alone, and I am wondering if this has some benefits.

  • Splitting up a Rails/Ruby app onto multiple servers

    - by craig.kaminsky
    We recently moved a large application to two machines, both running the same codebase. I. Machine A Web server for public facing application Receives web hook call backs from our ESP Handles a few large, list-processing jobs (uploaded spreadsheets with data) II. Machine B Manages a massive set of (background) jobs but, primarily, focuses on building and assembling newsletters Runs all integration with our NetSuite platform Runs all system maintenance (read: DB) jobs To me, having these two apps running the same codebase (a large, monolithic Rails application) seems 'wrong'. I am wondering if anyone has advice on how to better break up the code for these two apps. While they both need the same DB and, ultimately, the same model code, Machine B has no need for Controllers and Views and it feels wasteful running a full-stack Rails app for its tasks. A couple things came to mind but I'm not sure if I'm trying to solve a problem that doesn't exist: Break the models out into a sub-module on git and include into both apps Build out the Mahcine B app in plain Ruby or a lighter framework like Sinatra (where I could use ActiveRecord with Sinatra in combo with a sub-module for the model folder). I'm new to this scenario and appreciate any and all feedback or direction! Thank you.

  • How do I get Flash 10.2 RC + Crystal HD for HW accelerated video to work?

    - by Gee
    I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

  • What's the future of online gamedev. FLASH or UNITY?

    - by Cpucpu
    Currently, i develop for flash, not much ago i discovered unity, not yet played with it, but i have seen so far was cool. Here are my thoughts: Flash is more casual, start with cost less, in time and money. In unity you'd likely have to go more bussines-serious (real money). There are proven bussines models in flash, like adver-gaming, ads, micro-transactions. Have not seen much movement in this in Unity, too soon maybe. Flash is too heavy. By its nature(making games) Unity is way faster. Flash is 2d, doing something 3d with it turns weird and slow. Unity is natively 3d, not optimized for 2d though, it is likely feasible as well. I am overlooking the plug-in widespread, that gap will get closed over the time.

  • What's a good 2D animation program for Linux (an alternative for e.g. Flash CS)?

    - by Martin Zeltin
    I don't mean the flash player here, I'm talking about the flash program that i can make animations with. Like Adoble Flash CS (formerly known as Macromedia flash). Is there a program on linux that i can make animations? I want to make a movie like animator vs animation. I used easy gif animator on windows lol it was a bit harder than flash but i'm on linux and I'd like to know what it has to offer. Worse case scenario, what gif animators are there on linux. :) Thanks!

  • Rails: The Law of Demeter [duplicate]

    - by user2158382
    This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. EDIT I completely understand and agree that this is still a violation and I need to create a method in Wallet called withdraw that handles the payment for me and that I should call that method inside the Customer class. What I don't get is that according to this process, my first example still violates the Law of Demeter because Invoice is still reaching directly into Customer to get the street. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

  • Roo gem .xlsx files performance problems [closed]

    - by alvaritogf
    I am getting unacceptable performace problems by using the roo gem for reading a file by using XLSX or XLS library from this gem. Someone may suggest me an alternative about how to parse an .XLSX file? parsed_file = Excel.new(filename,false, :ignore) if (file_format.upcase == "XLS") parsed_file = Excelx.new(filename,false, :ignore) if (file_format.upcase == "XLSX") raise t "#{filename} is not an Excel file!" if (!parsed_file) parsed_file.default_sheet = parsed_file.sheets[0]#'Sheet2'#oo.sheets[1] first_row = parsed_file.first_row last_row = parsed_file.last_row first_column = parsed_file.first_column last_column = parsed_file.last_column #logger.info "#### Total Rows:#{last_row}, first_row:#{first_row}, last_row:#{last_row}, first_column:#{first_column}, last_column:#{last_column}" first_row.upto(last_row) do |current_line| # Stuff .... end Thanks

  • 3D rotation tool. How can I add simple extrusion?

    - by Gerve
    The 3D rotation tool is excellent but it only lets you rotate 2D objects, this means my object is wafer thin. Is there any way to add simple extrusion or depth to a symbol? I don't really want to use any 3rd party libraries like Away3D or Papervision, this is overkill for my simple 2D game. I only want to do this creating a couple motion tweens if possible. More Details: Below is what my symbol looks like (just with a bit more color). The symbol does a little 3D rotation and then flies away, it's just for something like a scoreboard within the app.
