I have a problem using assetsManager, if I use SceneLoader.ImportMesh everythings work:
BABYLON.SceneLoader.ImportMesh("", "public/Models/", "parte.stl", scene, function (newScene) {
// ...
});
but using assetsManager nothig works
var assetsManager = new BABYLON.AssetsManager(scene);
var meshTask = assetsManager.addMeshTask("model", "", "public/Models/", "parte.stl");
meshTask.onSuccess = function (task) {
console.log("successo");
task.loadedMeshes[0].position = BABYLON.Vector3.Zero();
}
meshTask.onError = function (task, message, exception) {
console.log("errore");
console.log(message, exception);
}
it doesn't enter in any function, not in .onSuccess and not in .onError.
Does someone know where is the problem?
Thank you
Well I guess you need to call assets manager.load()

I use the Microsoft bot framework to come up with a "simple" PoC bot. I used a tutorial as a basis and extend it.
I've a couple of basic functions for differet intents (ie. greetings, goodbye, etc) and one with some more logic in it (reqstatus).
The simple ones (ie greeting.js) return the answer nicely but the more complex one doesn't (reqstatus.js). Running the main code of reqstatus.js (without the first "const getReqStatus = (entity) => {") in a standalone script works.
server.js (main) -> see call in "if (intent) {"...
const getFeelings = require('./intents/feelings.js')
const getGoodbyes = require('./intents/goodbyes.js')
const getGreetings = require('./intents/greetings.js')
const getHelp = require('./intents/help.js')
const getReqStatus = require('./intents/reqstatus.js')
...
const bot = new builder.UniversalBot(connector)
// Intents based on definitions on recast
const INTENTS = {
feelings: getFeelings,
goodbyes: getGoodbyes,
greetings: getGreetings,
help: getHelp,
reqstatus: getReqStatus,
}
// Event when Message received
bot.dialog('/', (session) => {
recastClient.textRequest(session.message.text)
.then(res => {
const intent = res.intent()
const entity = res.get('request_number')
console.log(`UserName: ${session.message.user.name}`)
console.log(`Msg: ${session.message.text}`)
console.log(`Intent: ${intent.slug}`)
if (intent) {
INTENTS[intent.slug](entity)
.then(res => session.send(res))
.catch(err => session.send(err))
}
})
.catch(() => session.send('Sorry I didn\'t get that. '))
})
...
greetings.js -> Returns the string ok
const getGreetings = () => {
const answers = ['Hi, my name is SuperBot. Nice to meet you!', ]
return Promise.resolve((answers))
}
module.exports = getGreetings
reqstatus.js -> Does not return anything
const getReqStatus = (entity) => {
var request = require('request');
var request_number = entity.toLowerCase()
var output = [];
// Processing
var lineReader = require('readline').createInterface({
input: fs.createReadStream('netreqs.csv')
});
lineReader.on('line', function (line) {
var jsonFromLine = {};
var lineSplit = line.split(';');
jsonFromLine.req = lineSplit[0];
jsonFromLine.req_count = lineSplit[1];
jsonFromLine.req_type = lineSplit[2];
//...
var req_lowever = jsonFromLine.req.toLowerCase()
if (req_lowever == request_number) {
output.push( `Your request ${jsonFromLine.req} was received`);
// simplified
}
});
// Output
lineReader.on('close', function (line) {
if (output == '') {
output.push( `I was not able to find a request like ${request_number}.`);
}
console.log(output); // list output
return Promise.resolve(output);
});
}
module.exports = getReqStatus
I also tried to put getReqStatus in a function but that also didn't work.
After a lot of trying and googling I'm still stuck and wanted to ask the experts here. Thanks a lot in advance.
I think that the problem is that your getReqStatus isn't really returning anything. In your example getGreetings function you're actually returning Promise.resolve(answers) as the return value of that function.
However, in your getReqStatus function, you just set up a listener lineReader close event:
lineReader.on('close', function (line) {
if (output == '') {
output.push( `I was not able to find a request like ${request_number}.`);
}
console.log(output); // list output
return Promise.resolve(output);
});
You're returning a Promise resolved inside the anonymous callback function you're passing to lineReader.on() as second parameter. That is not the return value from the getReqStatus function itself, so that getReqStatus is not returning anything, as expected.
The code of that function runs correctly as standalone code, as you say, just because it sets the listener properly and it does what it has to do. However, that code just doesn't return a Promise when wrapped in a function.
What you would need is to return a Promise that wraps the lineReader.on close handler, like:
function getReqStatus(){
//...code
return new Promise( function(resolve , reject ){
lineReader.on('close', function (line) {
if (output == '') {
output.push( `I was not able to find a request like ${request_number}.`);
}
console.log(output); // list output
return resolve(output);
});
});
}
I say would because I really don't know if this code will work, I don't have any kind of experience with the Microsoft Bot framework and not used at all with the readline module. However, even if this doesn't solve your problem, I hope it will help you a bit understanding why your function doesn't return a Promise and how could you fix it.
I'm working with NW.js, in order to create a local websocket-client. I have the principle working, at the moment I'm refactoring my code to be more object oriented.
Websockclient.prototype.connect = function() {
if (!("WebSocket" in window)) {
alert("WebSocket is NOT supported!");
} else {
uri = "ws://" + this.host + ":" + this.port;
this.ws = new WebSocket(uri);
this.ws.onopen = function(evt) { this.onOpen(evt); }
}
};
Websockclient.prototype.log = function(message) {
if (this.logEn == true) {
console.log(message);
}
};
Websockclient.prototype.onOpen = function(evt) {
this.log("connected");
this.ws.send("Client says Hi!");
};
The connection open's correctly, however something fails in the Websockclient.prototype.onOpen function call. The error output is as follows:
[31910:31910:0530/115015:ERROR:edid_parser.cc(181)] invalid EDID:
human unreadable char in name
chrome-extension://oimdoepkkglchafiooagncfokloigedg/app/lib/websockclient.js:29
this.ws.onopen = function(evt) { this.onOpen(evt); }
TypeError: this.onOpen is not a function
at WebSocket.ws.onopen (chrome-> > extension://oimdoepkkglchafiooagncfokloigedg/app/lib/websockclient.js:29:47)
It looks like I have a mistake in the following:
this.ws.onopen = function(evt) { this.onOpen(evt); }
(NB: this is line nr. 29 in file websockclient.js)
I think this assignment is incorrect, but I'm a bit stuck here. Can somebody can please explain what I'm missing here.
thx to #Pimmol's comment I've solved the problem, The following line:
this.ws.onopen = function(evt) { this.onOpen(evt); }
Needed to be changed to the following:
this.ws.onopen = this.onOpen.bind(this);
For more info, see the following documentation:
"The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called."
In my AngularJS controller, I have the following code:
$scope.readMDB = function () {
var fs = require('fs');
var adodb = require('node-adodb');
var password = document.forms["mdbSelForm"]["pwd"].value;
var revSQL = fs.readFileSync('revenue.sql', 'utf-8');
revSQL = revSQL.replace(/(\r\n|\n|\r)/gm, " ");
revSQL = revSQL.replace(/[รค]/g, function () { return unescape("%E4") });
$scope.revenueSQL = String(revSQL);
console.log("revSQL: " + $scope.revenueSQL);
connection = adodb.open('Provider=Microsoft.Jet.OLEDB.4.0;Data Source=' + $scope.selectedMDB + ';Jet OLEDB:Database Password=' + password + ';');
// debug
adodb.debug = true;
connection
.query($scope.revenueSQL)
.on('done', function (data) {
var revAll = JSON.stringify(data);
var revenueData = JSON.parse(revAll).records;
fs.writeFile('./model/revenue.json', JSON.stringify(data), function (err) {
if (err) throw err;
console.log("revenue.json saved");
});
return true;
})
.on('fail', function (data) {
return false;
});
}
A similar code worked fine while not using Angular. Now, it doesn't work no more, because of the
connection.query($scope.revenueSQL)
part. More precisely, the $scope.revenueSQL is not recognized as the SQL Statement that it actually is. Putting the SQL directly, without reading it from a file, works fine. Still, looking at my console, I see that $scope.revenueSQL is exactly what I want. But being put as parameter into .query(), something seems to go wrong. Any ideas?
Try
$scope.revenueSQL = $scope.$eval(String(revSQL));
to execute the expression on the current scope and returns the result.
So I have this model :
'use strict';
var mongoose = require('mongoose');
var subscriberModel = function () {
var subscriberSchema = mongoose.Schema({
email: String
});
function validateEmail(email) {
var re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return re.test(email);
}
subscriberSchema.methods.validateSubscriber = function (subs, otherModel) {
var code = 0;
if (validateEmail(subs.email)) {
mongoose.model('Subscriber').findOne({'email': subs.email},
function(err, subscriber){
if (err) {
code = 2;
} else if (subscriber) {
code = 3;
} else {
subs.save(function(err){
if (err) {
code = 2;
}
code = 4;
});
}
});
} else {
code = 1;
}
};
return mongoose.model('Subscriber', subscriberSchema);
};
module.exports = new subscriberModel();
And I call it in another file that way :
var subscriberModel = require('../models/subscriber');
var subscriber = new subscriberModel({email: req.body.email.trim()});
var code = subscriber.validateSubscriber(subscriber, buyModel);
console.log('code = %s', code); // => displays "code = 0"
I guess it's a scope problem or something like that (because I don't use any callback -or maybe I should-) but I can't find nor the problem, nor the solution.
So, how can I get the returned code value ?
Thanks in advance.
[EDIT] : I found where the problem was and edited the code to explain it. So apparently my var is set in the callbacks of mongoose so now my question is; how do I wait for this callback to end as I need the result to display a message to the user in a webpage?
Okay so, I found the answer.
I edited my function validateSubscriber to send a callback: subscriberSchema.methods.validateSubscriber = function (subs, callback). And removed the otherModel occurences inside.
That way, when I call it in my other file I just have to do :
subscriber.validateSubscriber(subscriber, function(code){
buyModel.code = code;
console.log('code = %s', buyModel.code);
}
To get the code AND wait for the answer.
I hope it helped someone else.
I am attempting to implement an asynchronous method queue in Javascript as seen in this blog post
Here's what I have so far:
function Queue() {
this._methods = [];
this._response = null;
this._flushed = false;
}
(function(Q){
Q.add = function (fn) {
if (this._flushed) fn(this._response);
else this._methods.push(fn);
}
Q.flush = function (response) {
if (this._flushed) return;
this._response = response;
while (this._methods[0]) {
this._methods.shift()(response);
}
this._flushed = true;
}
})(Queue.prototype);
I can't seem to get it to work as advertised, although the code looks correct to me. When I call the flush function I get this._methods is undefined on the line while (this._methods[0]) {.
How are you using it? If you're doing:
var q = new Queue();
q.flush("foo");
...you shouldn't be getting that error, and I'm not: http://jsbin.com/iduji3
