is possible simulate candle instance in cocos2d. scene black , when candle appears lighten room in realistic way. if possible, how achieve effect? redirections, guidance welcome. thanks. please note, don't want light reflection algorithms, simple use. need game players life abillity see room. you should check out raycasting. if set cocos2d use box2d, can use box2d's raycasting method achieve effect. can make walls in room box2d rigid-bodies, , raycast candle origin number of points on circle around it. if raycast intersects wall, mark location of intersection. @ end can fill in area light inside polygon created of raycast intersection points.

i trying parse xml php single element json array. this have: $t = array(); $a=array("url"=>$test->channel->item->link); array_push($t,$a); echo json_encode($t);; which gives me this: [{"url":{"0":"http:www.example.com"}}] but i looking this: [{"url":"http:www.example.com"}] it seems $test->channel->item->link parses curly brackets {url} but if echo $test->channel->item->link , get: www.example.com without curly brackets. not sure if you're looking for, works :) $xmlstr = '<?xml version=\'1.0\' standalone=\'yes\'?> <container> <channel> <item> <link>www.example.com</link> </item> </channel> </container>'; $test = new simplexmlelement($xmlstr); $t = array(); $a = array("url"=>$test->channel->item->link

i have data structure, linked list, looks like struct listitem { void* data; struct listitem* next; }; typedef struct listitem listitem; typedef struct { listitem* head; pthread_rwlock_t lock; } linkedlist; i using pointer void* data because want make data structure polymorphic can use few different applications. to initialise list (allocate memory , initialise rw lock), pass function init_list(..). when pass pointer list follows, program hangs whenever try , perform further operations on list (e.g. push item it): int init_list(linkedlist* list /* borrowed - list initialise (probably unallocated) */) { list = (linkedlist*)calloc(1, sizeof(linkedlist)); // clear memory, head null pointer printf("allocated memory\n"); if (list == 0) { perror("calloc failed on allocating memory list"); return 1; } printf("initialising lock\n"); pthread_rwlock_init(&list->lock, null); return 0;

i have sql database 3 tables inside called... fruit name fruit color fruit price i attempting return random result each of these 3 tables give me example.... apple - green - $10 currently doing running following php 3 times (with different table each) $result = mysqli_query($con,"select * fruitname"); while($row = mysqli_fetch_array($result)) { echo $row['fruitname']; } this works fine feeling going wrong way. there way 1 command instead of three? if want random row, can way: select * (select * fruitname order rand() limit 1) fn cross join (select * fruitcolor order rand() limit 1) fc cross join (select * fruitprice order rand() limit 1) fp this returns fields in 1 row. note random row different arbitrary row. random row means each row has equal chance of being selected. arbitrary row indeterminate. first row in select without order by arbitrary, not random.

i want archive (or delete) posts after 24hours. possible ? when user logs in after 24hours previous post not shown instead link create new post next 24hours. not matter if previous posts gets deleted love learn to both ways. cheers one way without having alter or destroy data post use scope on record. example, like: scope :recent_posts, lambda { where("created_at <= ?", (time.zone.now - 24.hours).to_s(:db)) } a couple things understand this: any place want have recent posts appear, have use .recent_posts scope the lambda needed because causes current time (time.now) evaluated @ run time every time scope invoked; doing no lambda make evaluation of time.now static , not change on time. the .to_s(:db) ensures timestamp formatted correctly evaluation database. it assumes have timestamps on posts table. it possible apply default_scope used every query against model except explicitly excluded. regarded bad practice because it's easy make mistakes not

i using fantastic kineticjs javascript framework illustrations. i have number of tweens in illustrations funky transitions. my problem am trying move kinetic.line() object across illustration smoothly. the docs kineticjs can use tweens transition "any numeric property of shape". know points in kinetic.line() object not numeric, object property. there way access kline_movingline.attrs.points[0].x used in tween. my lines simple. have 2 points (from , points). you can still tween line tween shape changing it's properties! var line = new kinetic.line({ x: 100, y: 100, points: [0, 0, 50, 50], stroke: '#ff0000' }); var tween = new kinetic.tween({ node: line, duration: 1, x: 400, y: 30, points: [100, 50, 25, 0] }); in above example, used tween change x, y , points properties. check fiddle , see works expected: jsfiddle

is possible in c language: typedef struct s { char a; int b; int c = this.a * 60 + this.b; } s; such type of structure usefull in code. no, in c can't assign remember value in declaration, compilation time error. but 1 solution can suggest(may like): #define init(this, a, b) {a, b, (this).a * 60 + (this).b} and call it: s s = init(s, '5', 6);
