ios - Cocos2d-iphone. "touchBegan" method and returning a value -


i developing game using cocos2d-iphone 3.0. use bool make code inside (after user touches sprite) implemented once. when user touches sprite second time, code not implemented. problem is, xcode says touchbegan method should not return value ( return no ;). how can change method, there no mistake? should change else? way correct @ all?

bool firstclicked = false; -(void) touchbegan:(uitouch *)touch withevent:(uievent *)event {  if(firstclicked==true)  {     return no ;  }   cgpoint location = [touch locationinview: [touch view]]; cgpoint convertedlocation = [[ccdirector shareddirector] converttogl: location]; cgpoint convertednodespacepoint = [self converttonodespace:convertedlocation];  if (cgrectcontainspoint([_sprite boundingbox],convertednodespacepoint))     {  firstactfirsttimeclicked=true; .......// code. not important  } }

if need once, want deactivate touch began on sprite. in custom overriden sprite : 

-(void) touchbegan:(uitouch *)touch withevent:(uievent *)event {  {     // awesome game related code on here     self.userinteractionenabled = no;  }

this should work on custom ccsrpite. way don't have handle silly position code in scene, , ready go 1 line of code.

obviously need enable user interaction when creating ccspritein order touchbegan called in first place.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
