i'm developing cocos2d-x game (version 3.8). game uses chipmunk physics , has static body works interruptor. interruptor enabled when body on it. interruptor disabled when bodies separate each other. i want to: moving body don't collision interruptor. has cross interruptor no bounce i want detect when moving body separates interruptor my first approach implementing oncontactbegin method. return false when 2 bodies in touch. way body crosses interruptor , not bounce. the problem oncontactseparate method not called, because contact did not happen. if return true in oncontactbegin method, oncontactseparate called , can detect it. problem body not cross interruptor, bounces. [edit] more info this scenario 2 sprites separated. ball can move , interruptor static body. ball on interruptor. this scenario 2 sprites in contact , object1 (the ball) on interruptor. want detect 2 sprites separate each other. any appreciated! it seems me using box2d with...

i'd know fastest , efficient way multiply array elements using javascript. var array = ["1", "2", "3", "4"]; so outcome total 10. first, values strings, not numbers, first thing make them numbers: array.map(number) then multiply .reduce array.map(number).reduce(function(product, value) { return product * value; }); edit — comment wisely notes * operator try convert operands numbers anyway. explicit conversion numbers, add filter see if there nan values produced, nan spreads cancer wouldn't matter. consider numeric conversion optional. now, in general , if getting array of numbers-as-strings api, i'd inclined explicit conversion, because in sense means there's wrong design of api. i'd prefer isolate "interesting" code weird stuff that.

i've been using shelve library python (not in multiprocessing environment), , i've been observing unstable behaviour when using has_key() method. returns true , false, when know key exists in shelve. usual cause of such behaviour? import shelve some_key = 'not relevant' s = shelve.open('cache.db') if s.has_key(some_key): var = s[some_key] print 'found key', some_key s.close() note: python 2.7, ubuntu 14.04 in vm virtualbox, running in i7 x86-64bit

i have problem: have 2 lists pipe_sizes = [15,15,22,15,32,45] flow_rate = [0.1,0.3,1,2,0.4,1.5] i use logical operators change list pipe_size like: if flow_rate <= 0.2 pipe size 15 if flow_rate > 0.2 , <= 1 pipe size 22 if flow_rate > 1 , <=1.9 pipe size 32 if flow_rate > 1.9 pipe size 45 how can it? pipe_sizes irrelevant generating ouput because possible flow rate / pipe size combinations covered in list of conditions. can generate result directly: def flow_rate_to_size(rate): if rate <= 0.2: size = 15 elif 0.2 < rate <= 1: size = 22 elif 1 < rate <= 1.9: size = 32 else: size = 45 return size flow_rates = [0.1, 0.3, 1, 2, 0.4, 1.5] pipe_sizes = [flow_rate_to_size(rate) rate in flow_rates] print(pipe_sizes) output: [15, 22, 22, 45, 22, 32]

i read image , change format without saving it. for example can read image this bufferedimage img=imageio.read(new file(filename)); then want change format of img , example jpeg png. way found use imageio.read write , read new image, seem efficient way it. when "read" image via bufferedimage img=imageio.read(new file('myimage.png')); you not reading decoding it, i.e., transforming raw bytes in (say) png format "raw" format aplication or api can manipulate (or display) - in case, bufferedimage . once done, fact image came png file forgotten. read png , save jpeg need decode (as png) , code (as jpg). i read image , change format without saving it. the "format" of image (in png/jpeg sense) gives way of packing image in sequence of bits. so, desire makes little sense. @ most, store bits in memory (what for?), same "saving it" (to memory instead of disk).

what null pointer exceptions ( java.lang.nullpointerexception ) , causes them? what methods/tools can used determine cause stop exception causing program terminate prematurely? when declare reference variable (i.e. object) creating pointer object. consider following code declare variable of primitive type int : int x; x = 10; in example variable x int , java initialize 0 you. when assign 10 in second line value 10 written memory location pointed x. but, when try declare reference type different happens. take following code: integer num; num = new integer(10); the first line declares variable named num , but, not contain primitive value. instead contains pointer (because type integer reference type). since did not yet point java sets null, meaning "i pointing @ nothing". in second line, new keyword used instantiate (or create) object of type integer , pointer variable num assigned object. can reference object using dereferencing operator .

i need write following method: accepts 2 integer parameters , returns integer. if either integer not 4 digit number method should return smaller integer. otherwise, method should return 4 digit integer made of smallest digit in thousands place, hundreds place, tens place , ones place. cannot turn integers strings, or use lists, or arrays. for example biggestloser(6712,1234) returns 1212 example biggestloser(19,8918) returns 19 here's how i've started write it: public static int biggestloser(int a, int b){ if(a<9999 || b<9999){ if(a<b) return a; else if(b<a) return b; } int at=a/1000; int ah=a%1000/100; int an=a%100/10; int ae=a%10; int bt=b/1000; int bh=b%1000/100; int bn=b%100/10; int be=a%10; if(at<bt && ah<bh && an<bn && ae<be) return at*1000+ah*100+an*10+ae; else if(at<bt && ah<bh && an<bn &...

i tried understand these 3 attributes in xsd definition. not sure if right . please correct me .if wrong. thanks compared java class definition xsd definition. the targetnamespace package definition of java class. indicating members including fields , properties , class belong targetnamespace . and need import class members other class consuming them. xmlns , xmlns:someprefix work for. , xmlns default one. yes, targetnamespace tells scope elements of xsd reside in. similar package not same tags inside xml file reside in targetnamespace. on other hand, in java instance variables/methods not belong package directly, belong class. xmlns:someprefix provides convenient "someprefix" alias imported xml schema's namespace. xmlns not not import members of targetnamepace have separate xsd:import tag. rather, referring namespace. can of course use in conjunction xsd:import have "java import like" effect.

i'm new type script, browsing tutorial , trying coding in playground found strange. for example code: class foobar implements ifoobar { full: string; constructor (public foo, public bar) { this.full = foo + bar; } } interface ifoobar { foo: string; bar: string; } function test(ifoobar: ifoobar) { return ifoobar.foo + ifoobar.bar; } var obj = new foobar("hello", "world"); document.body.innerhtml = test(obj); works if put class foobar implements ifoobar or just class foobar so what's point of using interface if contract not enforced? update main concern on line: document.body.innerhtml = test(obj); this should throw error right since foobar doesn't use implements ifoobar, , test(ifoobar: ifoobar) specified in method argument should accept ifoobar. me feels typescript plainly think foobar implements ifoobar though isn't. typescript uses duck typing , means if members match, type...
