so have been looking around , trying tutorials can't seem collision detection systems work. if able explain doing wrong or syntax errors great. player right touch object works player left touch object works 1--not working jump on objects 2-- not working hit top of objects i'm new in javascript first serious project while if http://codepen.io/guntarwii/pen/ebmnwb function startgame() { gamearea.start(); } var gamearea = { canvas: document.createelement("canvas"), start: function () { this.canvas.width = 720; this.canvas.height = 500; this.context = this.canvas.getcontext("2d"); document.body.insertbefore(this.canvas, document.body.childnodes[0]); this.interval = setinterval(updategamearea, 20); // console.log(gamearea.context) document.addeventlistener("keydown", optiones.moveme); ...

when “copy image” on web (by highlighting image , ctrl+c) , passed text view of html wysiwyg editor (not source code editor) picture displayed. though paste in text editor ( source code editor), content of clipboard understood editor html code. for example, if paste “<img src="someurl" /> in text editor, added in source code “<p>&lt;img src="someurl" /&gt;</p>” clipboard isn’t understood editor html code. so how should modify content of clipboard html wysiwyg editor understand html code though pasting in text view (not source code editor)? what want in more details: when have url of image stored in clipboard, want able add image html wysiwyg editor without having switch source code editor. transform content of clipboard (by adding code before , after url) understood html code (just example mentioned above) html wysiwyg editor. edit: better target answer here try achieve. when use sharex upload picture, sharex store auto...

i have simple 3 column (divs) page center content column bounded 2 sidebars. sidebars remain relatively static content column being dynamic page-to-page. goal ensure sidebars retain same height content column , after mashing in css, figured simple jquery solution far cleaner. enter following code: $(document).ready(function () { setdivattributes(); }); function setdivattributes() { $("#sidebar-left").height($("#content").height()); $("#sidebar-right").height($("#content").height()); } this works perfect, when runs , therein lies problem. can't simple bit of code run reliably. works fine in jsfiddle when run in various browsers, inconsistent behavior. load perfect. need refresh once, multiple times , have restart whatever browser altogether. figured maybe code running before content div had finished loading every solution i've encountered fails solve problem. i suspect there simple solution has evaded me far. ...

i'm new javascript, please bear me. wrote function returns difference between highest , lowest number in array: // function 1 function range (arr) { var max = math.max.apply(null, arr); var min = math.min.apply(null, arr); var max_diff = max - min; return max_diff; } console.log(range([6,2,3,4,9,6,1,0,5])); // 9 however, before came solution, tried approach: // function 2 function range (arr) { var max = function (arr) { return math.max.apply(null, arr); } var min = function (arr) { return math.min.apply(null, arr); } var max_diff = max - min; return max_diff; } console.log(range([6,2,3,4,9,6,1,0,5])); // nan this function returns "nan". read on nan, it's still not clear me why "nan" result. the other strange thing is: if put function 2 before function 1, second function returns correct result (9). whaaaat? you subtracting 2 functions, max , min . functions first coer...

i want make realtime application, involves finding edges of binary mask. need fast, without gpu if possible, runs below 0.0005 secs per image, size (1000,1000). using following example of binary image ,with size (1000,1000).

i wondering if there's way use benefits of meteor.js tracker graphql data layer react view. auto-updating view, updating props when content changes in database. know there mutations, in fetching again data once has been called? it depends on context of application, needs refetch query after mutation affect change on ui. you need ask questions : do need real time data synchronization on several users screen do need performant web application when real time data tracking not worry. if performance constraint i'd suggest go 100% graphql solution, if need user collaboration easiest way go meteor tracked data, costs lot in memory.

given list of words, trying figure out how find words in list made of other words in list. example, if list ["race", "racecar", "car"] , want return ["racecar"] . here general thought process. understand using trie sort of problem. each word, can find of prefixes (that words in list) using trie. each prefix, can check see if word's suffix made of 1 or more words in trie. however, having hard time implementing this. have been able implement trie , and function prefixes of word. stuck on implementing compound word detection. you present trie nodes defaultdict objects have been extended contain boolean flag marking if prefix word. have 2 pass processing on first round add words trie , on second round check each word if it's combination or not: from collections import defaultdict class node(defaultdict): def __init__(self): super().__init__(node) self.terminal = false class trie(): def __init__(self...
