Java HashMap - String to bukkit Vector? How? -


i didn't see answered question , i'm stuck. gist of i'm storing vector inside hashmap string, so:

notes.put(notes.size()+1), player.getlocation().getdirection().tostring());

notes hashmap name. since hashmaps seemingly store strings, need way convert vector.

later in code, implement vector later this:

`player.getlocation().setdirection(vector);`

when couldn't think of way around conversion, tried mathematical way of calculating direction facing so:

`double pit = ((parsed[4]+ 90) * math.pi) / 180; double ya = ((parsed[3]+ 90) * math.pi) / 180; double newx = math.sin(pit) * math.cos(ya); double newy = math.sin(pit) * math.sin(ya); double newz = math.cos(pit); vector vector = new vector(newx, newz, newy);`

pit being pitch , ya being yaw. parsed[3] , parsed[4] original pitch , yaw of player. again didn't work , sent error server console. [error]: null. in short, want way convert string vector. i'd prefer not math way if don't have choice, it. , constructive criticism appreciated; in advance!

as side note: i'm new java have experience in c , javascript, lot of things familiar me.

hashmaps aren't limited storing strings. can store object, including vectors

map<integer, vector> mymap = new hashmap<integer, vector>();

so, instead of worrying converting string vector, store vectors in hashmap

map<integer, vector> notes = new hashmap<integer, vector>();  //add vector map notes.put(notes.size() + 1, player.getlocation().getdirection());  //get vector out of map vector playervector = notes.get(notes.size());

also, way you're writing it, use arraylist

list<vector> notes = new arraylist<vector>();  //add vector array notes.add(player.getlocation().getdirection());  //get vector out of map vector playervector = notes.get(notes.size());

if change string vector reason, use

//get x, y, , z values of vector array string[] components = vectorstring.split(",");  //components[0] x value, [1] y, , [2] z. double x = double.valueof(components[0]); double y = double.valueof(components[1]); double z = double.valueof(components[2]);  //construct vector using components vector myvector = new vector(x, y, z);

c# - Validate object ID from GET to POST -

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
