Matter.js Compound Collision Clipping -


compound bodies clip dramatically, , results in variety of glitches, example this. seems occur when there's parts in 1 compound. i'm not sure if i'm doing wrong or if bug.

// module aliases  var engine = matter.engine,    render = matter.render,    world = matter.world,    bodies = matter.bodies;    // create engine  var engine = engine.create();    // create renderer  var render = render.create({    element: document.body,    engine: engine  });    engine.run(engine)  var composite = matter.body.create();    var bodya = matter.bodies.rectangle(0, 0, 100, 100)  var bodyb = matter.bodies.rectangle(0, 0, 100, 100)  var bodyc = matter.bodies.rectangle(0, 0, 100, 100)  var origin = matter.bodies.rectangle(0, 0, 20, 20)  world.add(engine.world, [composite])  matter.body.setparts(composite, [origin, bodya], true)  var ground = matter.bodies.rectangle(500, 800, 2000, 400)  world.add(engine.world, ground)  matter.body.rotate(composite, 5)  matter.body.setposition(composite, {    x: 500,    y: 0  })  matter.body.setstatic(ground, true)  settimeout(function() {    addrelative({      body: bodyb,      composite: composite,      position: {        x: 0,        y: 100      }    })    settimeout(function() {      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: 0        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: 100        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: 200        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: 300        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: -100        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: -200        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: 100,          y: -300        }      })      addrelative({        body: matter.bodies.rectangle(0, 0, 100, 100),        composite: composite,        position: {          x: -100,          y: 100        }      })        world.remove(engine.world, composite);      settimeout(function() {        world.add(engine.world, composite);      }, 10)      }, 500)  }, 00)    function addrelative(obj) {    //obj.body    //obj.composite    //obj.position        var bodyb = obj.body    var composite = obj.composite    var origin = composite.parts[1]    var angularvelocity = composite.angularvelocity;    var velocity = composite.velocity;    matter.body.setposition(bodyb, {      x: origin.position.x + obj.position.x,      y: origin.position.y + obj.position.y    });    var newvector = matter.vector.rotateabout(bodyb.position, composite.angle, origin.position);    matter.body.setposition(bodyb, newvector);    matter.body.setangle(bodyb, composite.angle);    var arr = composite.parts.slice();    arr.shift();    arr.push(bodyb)    matter.body.setparts(composite, arr, false)    matter.body.setvelocity(composite, velocity);    matter.body.setangularvelocity(composite, angularvelocity);  }    render.run(render);  var renderoptions = render.options  renderoptions.showaxes = true;  renderoptions.showpositions = true;  renderoptions.showconvexhulls = true;
body {    background: #222;    text-align: center;  }
<script src="https://cdnjs.cloudflare.com/ajax/libs/matter-js/0.12.0/matter.js"></script>

wondering if there's fix / workaround.

currently hit brick wall in project because of this.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
