• Access variables from a number of sources

  - by mac_55

  I'm creating my first game, and I've currently set up a 'GameState' class, to store player health etc. inside. This class is currently instantiated from the AppDelegate as I need to access it from all over my game. This is fine. For each class I'm working in, I can access the app delegate, and then find the GameState object... however, it seems very messy. I'm tempted to find a way (I'm still a newbie) to define the GameState instance as being some sort of global variable so that I can access it from all over with ease... but my little bit of reading on variable scope makes me uneasy about doing this, even if I knew how. Any ideas of the best way to define and access this class? It'll be used for everything from player health, to items they've found, any personalisation etc. Thanks!

• Jquery Text Variable

  - by Batfan

  I am trying to get jquery to pick up variable that I am defining and I'm having issues doing it. $.ajax({ url: "sitemap.php", cache: false, success: function(html){ $("#results").append(html); var $seriestitle = $("#define-title").text(); $('#results a:contains("$seriestitle")').addClass('current-series'); $('a:not(".current-series")').hide(); } }); This is the code I am using. You can view the page at the following URL: http://benjammindesigns.com/XML/details/1231.html There is a span on the page, with the ID 'define-title', that contains text. I am trying to pull the text from that span and use it as my variable. Any info is greatly appreciated.

• passing value of sqlplus variable from one script to another.

  - by FrustratedWithFormsDesigner

  I have a script that gets the current time, and must pass it to another script. variable v_s_time varchar2(30); exec :v_s_time := to_char(sysdate,'YYYY-MM-DD HH:MI:SS AM'); --Lots of unrelated code here variable v_e_time varchar2(30); exec :v_e_time := to_char(sysdate,'YYYY-MM-DD HH:MI:SS AM'); @"test report script.sql" :v_s_time :v_e_time; --yes, I also tried ":v_s_time", didn't seem to do anything. This does not work, it seems that the literal :v_s_time is passed to the script, instead of what I want: "2010-04-14 05:50:01 PM". To execute this manually, I could enter: @"test report script.sql" "2010-04-14 05:50:01 PM" "2010-04-14 05:57:34 PM" I found that what does work is this: define v_s_time = "2010-04-14 05:50:01 PM" --Lots of unrelated code here define v_e_time = "2010-04-14 05:57:34 PM" @"test report script.sql" "&&v_s_time" "&&v_e_time"; But it is unrealistic to hardcode the datetimes. Anyone know how to handle this? (Oracle 10g)

• javascript arrays: adding entries

  - by Lyon

  Hi, I'm not sure how I would do this in Javascript. I want to create an array that would contain any number of error messages from my form. I read on websites that you define the key for that array when adding new entries. // Javascript var messages = new Array(); messages[0] = 'Message 1'; How can I add entries into my array using a similar method I normally do in PHP // PHP $messages = array(); $messages[] = 'Message 1'; // automatically assigned key 0 $messages[] = 'Message 2'; // automatically assigned key 1 Is it possible to emulate that in Javascript? I don't want to have to define the number of entries in my array as it can vary. Thanks for helping me out on this very basic js question. -Lyon

• difference equations in MATLAB - why the need to switch signs?

  - by jefflovejapan

  Perhaps this is more of a math question than a MATLAB one, not really sure. I'm using MATLAB to compute an economic model - the New Hybrid ISLM model - and there's a confusing step where the author switches the sign of the solution. First, the author declares symbolic variables and sets up a system of difference equations. Note that the suffixes "a" and "2t" both mean "time t+1", "2a" means "time t+2" and "t" means "time t": %% --------------------------[2] MODEL proc-----------------------------%% % Define endogenous vars ('a' denotes t+1 values) syms y2a pi2a ya pia va y2t pi2t yt pit vt ; % Monetary policy rule ia = q1*ya+q2*pia; % ia = q1*(ya-yt)+q2*pia; %%option speed limit policy % Model equations IS = rho*y2a+(1-rho)yt-sigma(ia-pi2a)-ya; AS = beta*pi2a+(1-beta)*pit+alpha*ya-pia+va; dum1 = ya-y2t; dum2 = pia-pi2t; MPs = phi*vt-va; optcon = [IS ; AS ; dum1 ; dum2; MPs]; He then computes the matrix A: %% ------------------ [3] Linearization proc ------------------------%% % Differentiation xx = [y2a pi2a ya pia va y2t pi2t yt pit vt] ; % define vars jopt = jacobian(optcon,xx); % Define Linear Coefficients coef = eval(jopt); B = [ -coef(:,1:5) ] ; C = [ coef(:,6:10) ] ; % B[c(t+1) l(t+1) k(t+1) z(t+1)] = C[c(t) l(t) k(t) z(t)] A = inv(C)*B ; %(Linearized reduced form ) As far as I understand, this A is the solution to the system. It's the matrix that turns time t+1 and t+2 variables into t and t+1 variables (it's a forward-looking model). My question is essentially why is it necessary to reverse the signs of all the partial derivatives in B in order to get this solution? I'm talking about this step: B = [ -coef(:,1:5) ] ; Reversing the sign here obviously reverses the sign of every component of A, but I don't have a clear understanding of why it's necessary. My apologies if the question is unclear or if this isn't the best place to ask.

• Transportation Web App - utilizing google or bing map api

  - by BillS

  I am working on a transportation web app and I am having a bit of a problem. First, I want to be able to define a shipping corridor, say like I-95 between Baltimore MD and Richmond VA. And store what parameters I need to define this route. Users will then use a web interface and can select various routes, in this case, I-95. Vendors will be posting constantly changing pickup locations in the application database which have a shelf life of about 2 days. Some of these locations maybe along this route. I am storing the LAT and LONG for the specific location right now. If any of these points ARE along or within 2 mile of the route (just off the highway basically - the ideal check would based on an actual highway exit but at this point anything would work), I want them to show up in my search results. Any ideas or suggestions?

• Slime in emacs seems has conflicts with autopair

  - by Boris

  I have just install slime in emacs. And after removed all the other plugins for debuging, I found that slime seems had conflicts with autopair.(Or a bug of autopair?).In slime, when I typed C-c C-c, the minibuffer displayed error like: error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil Even more, the error message still alerted after I killed the slime buffer. If I also remove the autopair plugin, slime works just fine. Can anyone tell me how to solve this? Thanks. :)

• Issue in exec method

  - by mukul sharma

  Hi all, I am a having two python files file1.py and file2.py. I am using exec() to get the method/Variables defined in the file2.py. file1.py have a class as given below class one: def init(self): self.HOOK = None exec(file2.py) self.HOOK = Generate ### call the hook method #### self.HOOK() file2.py looks like as (There is no class define in file2.py) def Generate() do 1 do 2 Hello() def hello() print "hello" Now the problem is as When i run script it is giving a error global name Hello not found. If i remove Hello() from Generate method in file2.py then its work fine. I cant use import file2.py in file1.py,because in file2.py the only one method name (Generate) is fix (its taken as requirement). So apart from Genarate method user can define any method and can call this in generate method, because this approach is not working so i have to write whole code into generate method only and code is also repetitive. Any help is really appreciable...

• In SICP exercise 2.26 using DrScheme, why does cons return a list, instead of a pair of lists?

  - by limist

  In SICP exercise 2.26, this Scheme code is given: (define x (list 1 2 3)) (define y (list 4 5 6)) Then this cons call is given: (cons x y) I expected a pair of lists would result, ((1 2 3) (4 5 6)) but the interpreter gives, ((1 2 3) 4 5 6) ...a list with 4 elements, the first being a list. Why is y treated differently? I've tried looking up other SICP answers for an explanation, but couldn't find something satisfactory. So could any Scheme/Lisp experts please shed some light on this aspect of cons? Thanks in advance for any insight.

• directx 9 hlsl vs. directx 10 hlsl : syntex the same.

  - by numerical25

  For the past month or so I been busting my behind trying to learn directx. So I been mixing back back and fourth from directx 9 to directx 10. One of the major changes I've seen in the two is how to process vectors in the graphics card. one of the drastic changes I notice is how you get the gpu to recognize your structs. In directx 9 you define the Flexible Vertex Formats your typical set up would be like this... #define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) in directx 10 I believe the equivalent is the input vertex description D3D10_INPUT_ELEMENT_DESC layout[] = { {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0} }; I notice in directx 10. it is more descriptive. besides this, what are some of the drastic changes made. and is the hlsl syntax the same for both.

• Create an grid array...

  - by Anicho

  Okay so I am looking to create a grided array in OGRE3D game engine but the array is generic my array skills are pretty basic and need work so I am posting this just to be sure I am doing this correctly. #define GRIDWIDTH 10 #define GRIDHEIGHT 10 int myGrid [HEIGHT][WIDTH]; int n,m; int main () { for (n=0;n<HEIGHT;n++) for (m=0;m<WIDTH;m++) { jimmy[n][m]=(n+1)*(m+1); } return 0; } I am assuming the above will return: 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 Then I can assign each point in the array to a valid node in OGRE3D to create a grid in 3D view would this work? Just need to tell me if I am doing it right or wrong dont need the ogre3d code....

• What's the diffrence btw System property and system environment variable

  - by khue

  Hi all I am not clear about this. When I run a java App or run an Applet in applet viewer,( in the IDE environment), System.getProperty("java.class.path") give me the same as System.getenv("CLASSPATH"), which is the CLASSPATH env variable defined. But when I deploy my applet to webserver and access it from the same computer as a client, I get different result for the two (System.getProperty("java.class.path") only point to jre home and System.getenv("CLASSPATH") return null). And here is some other things that make me wonder: For the applet part, the env var JAVA_HOME, i get the same result when deploying the applet in a browser as well as Applet Viewer. And if I define myself a env variable at system level, and use getenv("envName") the result is null. Is there anyway I can define one and get it in my java program? Thanks a lot Regards K.

• C language preprocessor behavior

  - by khanna_param

  There are different kind of macros in C language, nested macro is one of them. Considering a program with the following macro #define HYPE(x,y) (SQUR(x)+SQUR(y)) #define SQUR(x) (x*x) Using this we can successfully compile to get the result. As we all know the C preprocessor replaces all the occurrence of the identifiers with the replacement-string. Considering the above example I would like to know how many times the C preprocessor traverses the program to replace the macro with the replacement values. I assume it cannot be done in one go.

• C# Getting Just Date From Timestamp

  - by Soo

  If I have a timestamp in the form: yyyy-mm-dd hh:mm:ss:mmm How can I just extract the date from the timestamp? For instance, if a timestamp reads: "2010-05-18 08:36:52:236" what is the best way to just get 2010-05-18 from it. What I'm trying to do is isolate the date portion of the timestamp, define a custom time for it to create a new time stamp. Is there a more efficient way to define the time of the timestamp without first taking out the date, and then adding a new time?

• OpenAL - determine maximum sources

  - by Bill Kotsias

  Is there an API that allows you to define the maximum number of OpenAL "sources" allowed by the underlying sound hardware? Searching the internet, I found 2 recommendations : keep generating OpenAL sources till you get an error. However, there is a note in FreeSL (OpenAL wrapper) stating that this is "very bad and may even crash the library" assume you only have 16; why would anyone ever require more? (!) The second recommendation is even adopted by FreeSL. So, is there a common API to define the number of simultaneous "voices" supported? Thank you for your time, Bill

• Static struct in C++

  - by pingvinus

  Hi, I want to define an structure, where some math constants would be stored. Here what I've got now: struct consts { //salt density kg/m3 static const double gamma; }; const double consts::gamma = 2350; It works fine, but there would be more than 10 floating point constants, so I doesn't want to wrote 'static const' before each of them. And define something like that: static const struct consts { //salt density kg/m3 double gamma; }; const double consts::gamma = 2350; It look fine, but I got these errors: 1. member function redeclaration not allowed 2. a nonstatic data member may not be defined outside its class I wondering if there any C++ way to do it?

• C++ - dynamic pointer of array

  - by Eagle

  Hi to all, first i would like to say i am Newbie in C++. As part of my master thesis i am writing a program in C++ which also get as parameters the variables m and d (both integers). Were d is the power of 2 (this means 2^d elements). Parameter m define the number of possible interactions between one element and the total group (2^d elements). The number of possible interactions is computed as following: \kappa = \sum_{i=0}^m\binom{d}{i} (at present i generate vector of vectors for 2^d x \kappa, but my Prof. would like me to create different statistics to different m's. My first though was to to generate a dynamic array of m arrays of different sizes... Then i though of defining a 3-dim array with the biggest needed 2d array, but also program speed is important (e.g d = 20). i would like to ask for your advice how to define such kind of dynamic array that will also be fast.

• the problem about different treatment to __VA_ARGS__ when using VS 2008 and GCC

  - by liuliu

  I am trying to identify a problem because of an unusual usage of variadic macros. Here is the hypothetic macro: #define va(c, d, ...) c(d, __VA_ARGS__) #define var(a, b, ...) va(__VA_ARGS__, a, b) var(2, 3, printf, “%d %d %d\n”, 1); For gcc, the preprocessor will output printf("%d %d %d\n", 1, 2, 3) but for VS 2008, the output is printf, “%d %d %d\n”, 1(2, 3); I suspect the difference is caused by the different treatment to VA_ARGS, for gcc, it will first expand the expression to va(printf, "%d %d %d\n", 1, 2, 3), and treat 1, 2, 3 as the VA_ARGS for macro va. But for VS 2008, it will first treat b as VA_ARGS for macro va, and then do the expansion. Which one is correct interpretation for C99 variadic macro? or my usage falls into an undefined behavior?

• Executing certain code for every method call in C++

  - by Luís Guilherme

  I have a C++ class I want to inspect. So, I would like to all methods print their parameters and the return, just before getting out. The latter looks somewhat easy. If I do return() for everything, a macro #define return(a) cout << (a) << endl; return (a) would do it (might be wrong) if I padronize all returns to parenthesized (or whatever this may be called). If I want to take this out, just comment out the define. However, printing inputs seems more difficult. Is there a way I can do it, using C++ structures or with a workaroud hack?

• Create xml type with no body

  Hopefully this is an easy question. How can I define an XML type such that the type doesn't have a body. As an example I can define the Foo type as follows... <xs:complexType name="Foo"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="id" type="xs:integer" use="required"/> </xs:extension> </xs:simpleContent> </xs:complexType> But that would allow the following... <Foo id="7">STUFF I DON'T WANT</Foo> Is there a way I can change the xsd so that the Foo element isn't allowed any body?
