box2d - c++ - raw pointer to shared_ptr -

i'm using box2d , may know, holds void* object can use reference when collisions occur between different entities. problem original item saved inside shared_ptr since ownership unknown , different classes (example player class) can 'equip' class (weapon). i'm wondering if possible put pointer inside shared_ptr , refer same object original one? this example: std::vector<std::shared_ptr<environment>> listenvironment; listenvironment.push_back(std::make_shared(new weapon())); //takes void pointer box2d->userid = listenvironment.back().get(); //some shit happens somewhere else , collision occurs , pointer box2d's callback: environment* envptr = static_cast<environment*>(box2d->userid); as can see envptr going cause trouble. there way refer old smart-pointer , increase reference value? ps: in actuality every class creates box2d body holds 'this' pointer don't have address smart-pointer either. example above kind narr...

javascript - Assign nested object to object JS -

this might have been asked before, didn't see question: is there way declare object in javascript such can directly assign values in multiple levels of nesting (without declaring each level along way)? example: var obj = {}; obj["key1"]["key2"]["key3"] = "value"; obj["key1"]["key4"]["key5"] = "value2; the above doesn't work me, since i'm creating object dynamically, creating each level along way each key costly i'd have check existence first.. ie: if (!obj["key1"]) obj["key1"] = {}; elseif (!obj["key1"]["key2"]) !obj["key1"]["key2"] = {}; ... etc i hope makes sense. it doesn't make sense way. i sure need in special case, recommend review purposes , use helper function instead. for example, setproperty(targetobj, path, value) path plain list ['key1', 'key2'] , can check existence there...

Python dictionary iteration order is unexpectedly sorted. Why? -

this question has answer here: will python dict integers keys naturally sorted? 5 answers a dictionary populated consecutive integer keys, this: d = dict() in range(0, 10): d[i] = 100-i later, dictionary items iterated this: for k, v in d.items(): print k, v the result shows items iterated in numerical order: 0 100 1 99 2 98 3 97 4 96 5 95 6 94 7 93 8 92 9 91 it turns out, behavior want, not expected. expected dictionary iteration in random order. what's going on here, , can depend on behavior in code released publicly? dictionaries not in random order. in arbitrary order. in case, got lucky , sorted. tomorrow, might not be. if need randomness, use random . if need sorted order, use sorted() . @benjaminwohlwend mentions in comments, can use collections.ordereddict keep track of insertion order. in case, guess dictionary do...
