pretty new cocos2dx , c++ objective-c background. i'm making game can have between 1-10 enemies on screen @ time. each enemy has 1 sprite body , 2 stats (health & damage). in past objective-c i've been able define class.h/class.mm file , fill many variables want (health, speed, height, weight, color, etc), i'm having trouble figuring out how in cocos2dx. here simplified project isolates problem i'm having. i'm sure it's straight forward i'm having trouble looking solution //-----enemy.h #include "cocos2d.h" using_ns_cc; class enemy : public cocos2d::layer{ public: virtual bool init(); create_func(enemy); void sethealth(int val); private: int myhealth; sprite *body; sprite *weapon; }; //-----enemy.cpp #include "enemy.h" using_ns_cc; bool enemy::init() { if ( !layer::init() ) return false; return true; } void sethealth(int newhealth) { //myhealth = newhealth; } //-----hellow

whats difference between containsvalue , contains method of hashtable http://docs.oracle.com/javase/7/docs/api/java/util/hashtable.html there isn't one. emphasis mine. returns true if hashtable maps 1 or more keys value. note this method identical in functionality contains (which predates map interface). so can use either one, perfer containsvalue() because bit more self-explanatory, that's me. the reason there 2 different methods same thing because hashtable implements map<k, v> interface. don't know if you've used interfaces yet, classes implement interface required have methods defined in interface . so, because map has definition boolean containsvalue(object value); classes implement (like hashtable ) has have method. that's why containsvalue() exists. then why have have contains() ? well, that's because contains() existed before map interface existed (see documentation snippet above). contains() came first, that

my system started life single winforms application single database using entity framework. down line, database branched off encompass new system extended new tables. main employee table renamed person, , associated fk references renamed term person in columns. the existing system has since changed in terms of database structure new tables added. something like: now want bring 2 databases in line, keeping person table on employee. need bring 2 entity frameworks together. need tips , pointers on how this. luckily new system still in uat not live. have base population scripts this. i use nhydrate maintain both entity frameworks - db first. database side of things can cope with. however, unsure of best way bring entity frameworks in line. there tools have used sync databases such red gate's sql compare. vs2013 has nice sql schema compare. i have couple thoughts on different ways this: thought 1 manually add changes through ef database designer generate

when add subview below uicollectionview, subview shows above uicollectionview cells. here subview insertion code: [self.collectionview insertsubview:self.garmentview atindex:0]; not sure if i'm not following best practice or otherwise missing obvious. assistance appreciated. ** edit ** might worth noting happens in landscape, when rightmost cell zoomed in. i think self.garmentview.layer.zposition = -1 [self.collectionview insertsubview:self.garmentview atindex:0]; will solve problem. guess can happen collection view cells gets added lower index garmentview. see question more thorough discussion subview positions.

so have developed program class of mine use actionlistener events when button clicked. have program working when clicking button have click input buttons multiple times answer register , move next level of program. example1: alert button open's 2 3 "hey there's bug on you!" message dialogs. example2: yes/no prompts 3-4 times return yes/no answer txt. example3: color takes 3/4 clicks before returning input txt. (i think picture...) for life of me cannot find out why won't take 1 input , move on... the code of program review... thank in advanced. import javax.swing.*; import java.awt.*; import java.awt.event.*; public class messageboxes{ private jbutton alert = new jbutton("alert"); private jbutton yesno = new jbutton("yes/no"); private jbutton color = new jbutton("color"); private jbutton vals = new jbutton("3 vals"); private jbutton input = new jbutton("input"); private jtextfield

i have expression: sin(x)+sin(y) there well-known trig identity express product of sin , cos. is there way sympy apply identity? simplify , trigsimp nothing. trigsimp , aristocrates points out, reverse, because sin(x) + sin(y) simpler 2*sin((x + y)/2)*cos((x - y)/2) . trigsimp internally uses algorithm based on paper fu, et. al. , pattern matching on various trigonometric identities. if @ source code , identities written out in individual functions (the functions named after sections in fu's paper). looking @ list of simplifications @ top of file, 1 want tr9 - contract sums of sin-cos products testing out, looks works in [1]: sympy.simplify.fu import tr9 in [2]: tr9(sin(x) + sin(y)) out[2]: ⎛x y⎞ ⎛x y⎞ 2⋅sin⎜─ + ─⎟⋅cos⎜─ - ─⎟ ⎝2 2⎠ ⎝2 2⎠ we factor these out more user-friendly functions, now, fu.py file pretty documented, if function names not particularly memorable.

this question has answer here: how convert lambda std::function using templates 6 answers i need accept lambda function parameter , figure out return type. far, couldn't come workable. here example: template <typename t1, typename t2> t1 foo(t2 arg, std::function<t1(t2)> f) { return f(arg); } ... int n = foo(3, [](int a){ return + 2; }); <-- error! how can done? boost solution ok, too. you shouldn't pass std::function parameter. has overhead because uses type erasure store type of callable, such function pointers, functors, lambdas (which automatically generated functor), etc. instead, should template function type. can use trailing return type figure out return type of function: template <typename t, typename function> auto foo(t arg, function f) -> decltype(f(arg)) { return f(arg); }

has deployed ember-cli + rails app in heroku one? https://github.com/bostonember/website if yes, how did/do deploy? i know ember-cli produces necessary code in dist/ dir, should placed (copied) under rails' public/ directory not sure how , when given heroku not allow write access in filesystem. if has done that, let me know :) the reason chose ember-cli instead of ember-rails gem don't want dependent on rails' gem developer. think ember-cli option long can deploy efficiently in heroku :d dockyard worked through example of during boston ember meetup. here's video . they posted code online, important part being deploy task of rakefile : task :deploy sh 'git checkout production' sh 'git merge rails-served-html -m "merging master deployment"' sh 'rm -rf backend/public/assets' sh 'cd frontend && broccoli_env=production broccoli build ../backend/public/assets && cd ..' unless `git statu

i want remove spaces(only ' ' , '\t' , '\r\n' should stay) string. have problem. example: if have string test = "902322\t\r\n900657\t\r\n10421\t\r\n"; string res = test.trim(); // res still "902322\t\r\n900657\t\r\n10421\t\r\n" res = test.trim('\t'); // res still "902322\t\r\n900657\t\r\n10421\t\r\n" but if have string test = "902322\t"; trim() work perfectly. why behavior? how can remove '\t ' string using trim() method? string.trim method deals whitespaces @ beginning , end of string so should use string.replace method string test = "902322\t\r\n900657\t\r\n10421\t\r\n"; string res = test.replace("\t", string.empty); // res "902322\r\n900657\r\n10421\r\n"

is there way total number of documents in mongodb database months (for example, can display chart showing evolution of number of users) in single request? or should request each month individually? i don't want see number of users created in month total (this month + previous months). each document in collection has field representing date created. total number of documents in mongodb database months, use range query query documents value created_on greater date representing start of month, , less date representing end. assume start date 'start' , end date 'end'. query be, db.users.count({created_on: {$gte: start, $lt: end}}); here nice explanation relevant topic. http://cookbook.mongodb.org/patterns/date_range/ refer answers in thread also. find objects between 2 dates mongodb

options -pg , -mfentry , -finstrument-functions affects functions in .c file, how can insert trace call specific functions, not all? i checked gcc function attributes seems there's no counterparts -pg , -mfentry , -finstrument-functions can used decorate specific functions. no_instrument_function excludes functions want opposite, i.e., includes functions. you can backtraces in c . method you'll have add code function want trace. here's simple example : #include <execinfo.h> #include <stdio.h> #include <stdlib.h> /* obtain backtrace , print stdout. */ void print_trace (void) { void *array[10]; size_t size; char **strings; size_t i; size = backtrace (array, 10); strings = backtrace_symbols (array, size); printf ("obtained %zd stack frames.\n", size); (i = 0; < size; i++) printf ("%s\n", strings[i]); free (strings); } /* dummy function make backtrace more inter
