I've been playing with the new Javascript changes and I've been enjoying it quite a bit.
I recently discovered I could do this:

'use strict';
class Fruit {
  constructor(setObscurity) {
    this.obscureVariable = setObscurity;
  }
}

class Cake {
  constructor() {
    this.reasonToExist = null;
  }
}


class SomethingUnrelated {
  constructor() {
    var fruit = new Fruit("SO OBSCURE");
    var cake = new Cake;
    this.getObscureness(fruit); // prints "This object is like, so obscure: SO OBSCURE"
    this.getObscureness(cake); // prints "It's like, not obscure at all!"
  }

  getObscureness(objRef) {
    if (objRef.obscureVariable !== undefined) {
      console.log("This object is like, so obscure: " + objRef.obscureVariable);
    } else { console.log("It's like, not obscure at all!")}
  }
}

Is it possible to do this in C++?

It is not, though it is in .NET languages with reflection.

[Berkin]

Fuck it, I'm done. I'm not writing out all these inflections by hand. Instead, I'm going to write an extension to Rant specifically for handling declination/inflection and dynamically creating the correct endings/umlauts.

I may be batshit crazy, but even I have limits!

i cant wait until this uni semester is over, i'm going to go back and remake my 3d rendering engine i made 2 semesters ago for 3d graphics programming, except this time it will actually fucking work.

last time i got it to load obj files but my projection was completely fucked. it was so close to working, if i had paid more attention in class i would have got it done properly.

This can probably be done in a slightly less contrived manner, but heres an example in D :v:
[url]http://ideone.com/DOrs7w[/url]

import std.stdio : writefln;

struct Fruit {
	
	string obscurity;
	
	this(string obscurity_level) {
		this.obscurity = obscurity_level;
	}
	
}

struct Cake {
	
}

template hasMember(T, string member) {
	enum hasMember = __traits(hasMember, T, member);
}

void main() {
	auto fruit = Fruit("SO OBSCURE");
	auto cake = Cake();
	getObscureness(fruit);
	getObscureness(cake);
}

void getObscureness(T)(ref T thing) {
	static if (hasMember!(T, "obscurity")) { //resolved at compile time
		writefln("This object is like so obscure: %s", thing.obscurity);
	} else {
		writefln("It's like, not obscure at all!");
	}
}

// stdout
This object is like so obscure: SO OBSCURE
It's like, not obscure at all!

For context, one of the guys behind D (Andrei Alexandrescu) has been trying to get compile time if's into C++ for a long time, though while he was still involved in the process around C++.

[SupahVee]

In C++ you can use the [URL="http://en.cppreference.com/w/cpp/experimental/lib_extensions_2#The_C.2B.2B_detection_idiom"]detection idiom[/URL] or many other tricks that can be easily found via google

[NoRegard]

Working on converting a Unity Oculus Rift DK1 project to DK2.
I notice the framerate is low, 40 fps-ish.
The weird thing is the only thing in the project is an engine-mesh.
So I ask the guy who made it 'is this a .cad model?' (has it even been optimized)
'no we reduced the polys'

I check. 148.738 triangles :disgust:

[QUOTE=Superbird;48686605]Is there an API I don't know about or are you just scraping? I started writing an iOS app but hated the idea of scraping to much.[/QUOTE]

I'm just scraping, which isn't too hard with the right tools. I'm planning on making it similar to a browser, maybe with some enhanced features through my own server.

[Ashleigh]

Has anyone ever wondered why sqrt(fps) isn't used to display framerates in games? It's linear (like frametime), and it increases with performance in a linear fashion.

For example when comparing 60 fps to 1000 fps, the 1000 fps seems insanely quicker from a numbers point, but it's only a little over 4 times quicker. If you compare sqrt(60) [7.75] to sqrt(1000) [31.62], you can intuitively compare them now, plus 1 unit at a high value is equal to the same time that a lower value is (unlike fps).

Some common framerates and their sqrt so you can see:

15  = 3.87
24  = 4.89
30  = 5.48
60  = 7.75
120 = 10.95
144 = 12
300 = 17.32

That doesn't look very linear?

I don't get it.

[Asgard]

Please tell me if I'm dumb but doesn't this confirm that?

[IMG]http://puu.sh/kcdul/badcc44f05.png[/IMG]

Math is not my strong suit

[Fourier]

1/60     = 0.01666667
1/1000 = 0.001

I don't know what he is speaking about

(1/60)/(1/1000) = 16.666667

Seems like difference between 60FPS and 1000 FPS is 16 tenfold, which is 4*4. (Four times squared)

What? FPS is only really misleading in the way that an extra frame at a low range means a much bigger performance gain than an extra frame in a high range. So the step from 20fps to 21fps is really massive, while the step from 100 to 101 fps is almost nothing.

What you really want is a logarithmic scale like 20*log10(fps), resulting in dB:

1    = 0dB
10   = 20dB
100  = 40dB
1000 = 60dB

This is a way better indicator of performance gain. Every time you gain 3dB, you doubled your performance.

[editline]Edit:[/editline]

This by the way also works with frametime. In fact, you will get exactly the same dB values if you insert the frametime instead of fps, except that you get negative values:

1    = -0dB
.1   = -20dB
.01  = -40dB
.001 = -60dB

every -3dB you doubled your performance

[Asgard]

Or just use frametime??

This thing has been solved for quite a while now

[DrLuke]

[QUOTE=Asgard;48687741]Or just use frametime??

Yeah but why would you fudge around with decimals if you could just use a logarithmic scale like dB? Then you don't have to think "oh that number just halved, so I doubled my performance". With dB you can directly compare different values and immediately see how much better it is.

[DrLuke]

[QUOTE=AtomiCal;48687786]Is this really important?[/QUOTE]

It is if you want to effectively compare values with different orders of magnitude.
