oh, concat for arrays, push for single objects

stupid javascript. give me a fucking error for that kind of thing.

@IcyDefiance Concat returns a new array

ohh that's good to know as well

var a = [1].concat([2, 3]);

You can also push single objects with concat: [1].concat(2);

1:52 AM

that would explain the lack of error

I am Error.

2:17 AM

okay, got that to work. now I can quit javascripting for tonight.

meanwhile: I'm trying to make the stupidest most useless (yet functional) jQuery

So far, so good

hahah

arithmetic.number(2).number(4).add().number(2).pow().number()

:( Some days, it would be nice if javascript threw more errors

At the very least, a "throw every error" mode

throw new Error(':P');

lol, yeah, I saw you guys post that question earlier today

What do you mean by errors? Are they just being swallowed somewhere or

yeah, JS ~~likes~~ loves to roll over errors

2:26 AM

@JohnMcDonald example

hmm, I had one a minute ago, now how to make it happen again?

Well... typos in variable names or selectors aren't "errors", but your code just doesn't do anything. That's a big one

@JohnMcDonald Use a linter, jshint, jscs

The variable name typos can be caught with strict mode, but selectors can't

yeah, I think I have lint on here somewhere

I was more sympathizing with Icy than anything.

I use SublimeLinter-jshint and also lint when bundling/building

I keep thinking about trying something else, but I'm pretty engrained in jEdit's ways

and it tells me I have JSLint going

2:37 AM

@JohnMcDonald "use strict";

inside whatever scope youd like js to complain about

and yes

derp my bad

im bad at returning to chat

5 hours ago, by John McDonald

yeah... I hate that. You can try adding the following to the top of the js file (literally):
"use strict";

Meh. It's all good, I do the same, :)

I'm making a little polish adder in jQuery, just because

2:49 AM

There, needsmorejquery.com uses some useless jQuery

3:23 AM

ugh, I am not enjoying Witcher 3's controls, it's like his walking acceleration is too slow but then he moves too fast soon after

right... I guess they are imitating that "first step"?

I'm not going to use articles tomorrow.

@JohnMcDonald yeah like tapping Up on the control stick for a moment has no effect

damn

have to hold it long enough to get your leg velocity going I guess :/ feels like I'm fighting it more than I should

3:31 AM

:( yeah, "realism" isn't always fun

4:22 AM

"The game is so realistic that you have to eat or your dude actually starts complaining. And then if you eat too much, he throws up everywhere. IT'S SO REALISTIC!!"

@OMGtechy I was about to ask why you hate JS so much. But then I remembered this: typeof NaN: "number"

lol

4:39 AM

NaN == NaN
false

>javascript

you'll shit brix...

So my English teacher made this Google forms form where we're supposed to submit feedback of the course. One of the radiobutton sets "is required" AND "expects 0 selections"...

Why do teachers even try to use computers?

6:26 AM

@AidanMueller Quite funny, but it's a he.

OMGtechy

8:15 AM

@AidanMueller this is the case in most languages

Uh yeah

It's the case in any language that follows the IEEE floating point standard

@AidanMueller also yes, there is a floating point representation for NaN so it's a number. It's s111 1111 1xxx xxxx xxxx xxxx xxxx xxxx (with s being the sign which is typically ignored and at least one of the x-es is non-zero (all zero is infinite)

Martin Sojka

8:44 AM

To be more precise: It's not a number, which is why using equality on it makes no sense.

You can always compare the binary representation of the value if you want to go around that.

(This will also allow you to differentiate between positive and negative zero)

The recommended way of checking if a number is NaN is to compare it with itself

(Barring evil operator overloading) that is the only way x == x will ever return false

And then there should be language functions to detect what type of NaN it is

nvm lol

Aah aight

didn't make any sense after I looked at it

Do you guys use a lot of static classes?

10:03 AM

nah... almost none

Considering I use C++? Nope

(Given that C++ does not have static classes)

@KevinvanderVelden you can implement "singleton" in C++

Not a static class

having global pointer is nice, but not being able to make another instances are not :P

In fact, that's quite a different thing, a singleton is where you only have one instance of it

10:04 AM

well how do you follow encapsulation then?

A static class is where you can only have static methods/variables

@KevinvanderVelden so what's the difference?

@Mutch95 the way every language but C# does it? C# is the only language (to my knowledge) that has static classes

i mean like for scripts made for specific things like a console

static methods/variables are basically instantiated only once :P

Pip

10:05 AM

@KevinvanderVelden Java

179

Q: Static Classes In Java

Is there anything like static class in java? What is the meaning of such a class. Do all the methods of the static class need to be static too? Is it required the other way round, that if a class contains all the static methods, shall the class be static too? What good are static classes?

java static-classes

Nope

just means i'd have to grab the object before i call methods from it then doesn't it?

also namespaces are almost identical to static classes, except they don't have access control

@Ali.S hmm true, the only actual useful difference between the two is that you can defer the instantiation of a singleton to a later point

@KevinvanderVelden but you can also not differ it....

also in C++ you can have an static class (by marking all it's fields and methods as static) you just can't force it to be static

10:08 AM

@Ali.S how do you mean?

@Ali.S yeah, but a static class means just that: you can't have non-static things in it.

class X{
static int f1;
static float f2;
public:
static int getF1();
static void setF1();
};

@KevinvanderVelden I mean like instantiating the static "instance" field in the application load time.

@Ali.S that's not what the word differ means =p. But of course you can, not that hard

differ as in "different"

hmm so I can't init a new object in another script if it is a child of MonoBehaviour?

Yes, differ: to be different. Still not what that sentence meant =p

Yes

What about it?

it's not possible?

I 'unno, which is why I hadn't replied to it. I only replied when you started with the ?? because it seemed to me you were demanding a response and I didn't like that

10:17 AM

O K sorry

trying to stop coffee drinking

i think i need a nap

Martin Sojka

@Mutch95 Some, for constants like "version of the binary" and "default buffer size".

Also a few math helper methods which don't fit nicely anywhere else, like discrete integration.

@Jon use half caff. It helped me transition off of caffeine

i've done it before... just need to get past the first week, lol

True.

10:26 AM

just a habit

i drink my coffee black too -- nothing really wrong with it -- just turning my teeth yellow and costing a decent amount of money

10:45 AM

Ditto. <3 coffee.

Say i have a hierarchy like so

is this = Console

consoleInput = this.transform.Find("InputText").GetComponent<Text>();

the find function wouldn't reach InputText

would it?

depends where your script is

in console

i ended up using a file path like so

consoleInput = this.transform.Find("Input/InputText").GetComponent<Text>();

you need to find the game object

I'm not sure if Find is recursive

10:56 AM

Findchild

it isn't recursive

transform.Find("Input").transform.Find("InputText")

There are other find types under the GameObject instead of the Transform

GetComponentsInChildren

this uses depth first search

aka, recurses

A better way however, is to use TAGS

FindGameObjectWithTag("Tag")

I watched the movie during weekends. It's surprisingly mature but also at the same time super kid-friendly.

Somewhat like Shrek

Looks fun

"You took my mom! How can I trust you?!"

yes watched that a while ago i really liked it

"You left me alone! I am just a kid. I am not supposed to be left alone!"

@Mutch95 I am planning to watch it again. It's been a long time since the last good animation.

might have to get the dvd

11:27 AM

dvd... yes me want dvd of this movie as well...

the movie's got cute-cartoonish characters that's far from "realistic" but the terms-lines in the movie are super serious, like the main character's companion alien gets threatened to be "erased"

I haven't seen a kid's movie where main character gets threatened to be killed.

toby

happens a lot in old warner bros cartoons

"old warner bros cartoons" Aye!!.... old cartoons are the best!

In Lilo and Stitch the commander doesn't give two shits if Lilo dies.

Packs her up with Stitch when he captures him.

Though to be fair he can play Elvis songs too, so the seriousness is toned down a tad..

I am trying so hard to remember who was the commander. Dang it. I was so young at the time I watched the Lilo and Stitch.... oh OK! It's the four eyed choby guy!

oh my goodnews there's a movie on youtube for free

11:48 AM

The commander is Captain Gantu.

While I've really not watched any significant amount of anime other than Dragonball Z... on a whim I started to watch Attack on Titan last night. I think I'm hooked.

Good choice

How much have you watched?

@Jon awesome!

Hey guys I'm dealing with a strange bug, need advice on how to debug properly. I'm using Unity3d and I'm communicating back and forth between Client side JS and Unity3d.

I have a grid such that if I click on one of the items in the grid in JS side, it makes a call to Unity to set an element so that I can drag it. However, when I select the element on the grid, I can't drag it in the unity view. How can I best debug this?

I tried sending out alerts but the alerts don't pop up

1:50 PM

@Lokkij I think I've finished 2 episodes... possibly 3 lol. The first episode really wowed me though.

Ah, yeah. The ending of the first one is good. You'll encounter another spectacular episode ending pretty soon. :)

Nice. Honestly this is your fault. I think Fisheye Placebo is what made me seriously consider watching it finally. It's been in the back of my mind for a while but I never took the plunge.

Aha, good! :D

@KalaJ can you go into detail on how your JS / Unity integration works? Are you using a library for the communication between them or is this something home brewed? Is this for a Unity game in the browser with JS that sits outside Unity in the same Window or is this something like Awesomium where the HTML / JS lives inside Unity?

@Lokkij I fear the impending anime / manga obsession I might get that I never asked for xD
