A couple of years ago I was building an online multiplayer game doing the frontend in Flash MX 2004 and using Colin Moock''s Unity server (http://moock.org/unity/) for the backend. This was to be along the lines of JungleWar and the Hidden and Dangerous mini games for those whom remember these: http://moock.org/unity/showcase/screenshots/hiddenanddangerous.gif

How can I use the drawing canvas and its off-screen image buffer, say FXImage, to dynamically resize or have its width and height attributes changed in reply to user interaction with the main window (FXMainWindow)? It seems that whem I put initial values to W and H of the canvas or FXImage, they remain with its initial values no matter what I do whem resizing the main window. -- Ranieri Barros

Hello, I want to save a pdf plot using Cairo, but the canvas of the saved file seems too large when compared to the actual plotted area. Is there a way to control the relation between the canvas size and the size of actual plotting area? Thanks in advance, and best regards, Eduardo Horta [[alternative HTML version deleted]]

I generate a lot of URL''s in my Facebook related code that point to our main site, not our FB app. My understanding was that the way to do this was to use ":canvas => false" as a parameter to url_for and link_to and so on. However, that doesn''t seem to generate the proper URL''s. The URL''s still point to apps.facebook.com (because they

Hi R world, I am such a newbie, with only 4-5 days of R experience. I did a search in forum history but couldn't find a solution to my problem... Sorry if it's obvious: I managed to draw a barplot (yey!) with xlabels of 'long' names (filenames, to be particular). To make them readable, I place them perpendicular to the axis (las=2). When I do that, however, these names don't

In Splus, I often use graphics windows with a black background and white foreground. The S print.graph() function sends the current plot to my printer but with a white background and black foreground. I'd like to be able to do something similar in R, but can't figure out how. I've tried various permutations of dev.copy() and dev.print(), but it seems that the foreground color is

I noticed something strange in my app today. It appears that the extra canvas path appended in url_for is back but only for controllers that are not resources. Here is an example I have in my site: campaigns is a resource checkout is not # With the canvas false flag (rdb:1) @controller.url_for(:controller => ''campaigns'', :action => ''show'', :id

I just encountered a bug that caused the links in my partials to be generated as non-canvas routes when the partial was loaded via ajax. This bug is due to facebooker url rewriting checking for fb_sig_in_canvas to determine if the application is running in or outside a canvas, and fb_sig_in_canvas is not sent for ajax requests. My hacked together patch diff is below, sorry I didn''t have

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Hi wxRuby Gurus, I''m trying to write a sample program which allows me to drag an image (by left_mouse_button down) across the canvas. I got it to work ... well, sort of. The problem is I can drag it only by clicking on the left top corner of the image and nowhere else. Besides, the dragging is not very smooth. How can I make it better? I am using wxRuby 0.6.0 on Win XP (Home) and

Hi, I am having trouble debugging this one. The code is attached below, but it seems to be a problem at the C-tk interface. If I run this 1 time there are no problems if I run it more than once I start to get warnings that increase in multiples of 11 everytime I run it. Here is a sample session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

I have been checking the params for params[:fb_sig] to detect if the client is in the Facebook canvas, but those don''t work at the beginning of a controller when you''re calling before_filters. I have a require_login in the before_filter, but I want to skip it if the user is from Facebook. So are there any other ways to check that the client is coming from the canvas?

The URLs for CSS/JS files are being rewritten to the address specified in the tunnel even when outside of the facebook canvas. Is anyone else having this problem?
