android - Painting texture in cocos2d-x -

-

i working on baby app , there bath scene in user applies soap baby's body. drags soap bar on body painting , soap bubbles appear on body wherever soap applied painting soap texture brush (soap bar).

i have soap bar sprite , texture sprite , baby sprite.

how can achieve effect ?

edit: have bubbles sprite. , want wherever user touches, opacity of point in sprite becomes 1 or 255. in start opacity 0 won't visible , when user drags soap on baby's body opacity become 255 every point user drags soap over.

here see soap bubbles sprite

i think achieve following way:

  1. place "baby bubbles" in cclayer (as sprite). background.
  2. create second layer in front of first , put cctexture2d it, filled white.
  3. whenever user touches screen, @ point, draw brush sprite texture. brush sprite must draw transparency.

this reference may help.

was helpful?

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
