Q: Get a SharePoint ListItem ID from a List where the 'Title' field is a specific value in JavaScript

I am trying to extract the ListItem ID of a List which I am currently NOT in based on a field value in that List. I cant find anything that explains how to do this. So, to explain. I have a Custom List called 'Department'. I have another Custom List called 'Article'. I have a field in the 'Artic...

It's SharePoint related! You're an expert!

Aidan Mueller

Just finished reading "Javascript: The weird parts"

Tried this afterward.

These values really should be reversed.

Or at least have min be 0.

William 'MindWorX' Mariager

min should only ever be 0 if it's an unsigned type.

SpartanDonut

6:56 PM

@AidanMueller I actually got to the Javascript: The Weird Parts page that elaborates on the reasoning behind that one... one sec.

charlieharvey.org.uk/page/why_math_max_is_less_than_math_min

William 'MindWorX' Mariager

Yeah, it's in the comments.

SpartanDonut

Ah well then

Aidan Mueller

Still is messed up.

SpartanDonut

I feel like both should return NaN or something

considering what the functions are for

William 'MindWorX' Mariager

Yeah, NaN or null.

Or just an exception.

Aidan Mueller

6:58 PM

That would be best.

SpartanDonut

Aidan Mueller

Javascript is stupid. I kind of like it but it's still stupid.

William 'MindWorX' Mariager

I don't get how it got to be the defacto for browser scripting. :P

I guess it's just the ease of it.

No need to install anything. Browsers just run it.

I think the most logical way would be to have both Math.max and Math.min return 0 when no arguments are given.

7:11 PM

@AidanMueller what game ?

Lokkij

@Almo You weren't kidding when you said Thrall is fun.

Aidan Mueller

This:

Lokkij

Damn he's so much fun to play.

Aidan Mueller

@Wardy I didn't make that.

Almo

@Lokkij :D yeah he's awesome

Wardy

7:12 PM

oh ok

I thought it was a screenshot of something you were building

is that kerbal space program ?

looking closer i can see that it looks like it now

I didn't really look before

lol

Aidan Mueller

Yes.

Wardy

I was just interested in the blue glow

Aidan Mueller

@Wardy You should play the game BTW.

Wardy

I have played it before

been a while though

i didn't get far ... i think i played with it when it was in beta

Aidan Mueller

Don't you mean alpha? It just barely went into beta.

Wardy

7:15 PM

must have been then

lol

Aidan Mueller

It's a lot of fun. You should watch scott manley's videos. They help a lot.

Wardy

My planet gen is coming along nicely now :)

Aidan Mueller

That's good.

Wardy

that's my latest

roughly 1/12th the size of earth (1km diameter)

Jon

we need to go bigger

Wardy

7:18 PM

im curious to see what a planet the size of earth might look like now ...

Aidan Mueller

@Wardy OpenGL?

Wardy

hmmmm time for some testing

@AidanMueller unity ... my voxel / noise toolkit based engine

Aidan Mueller

Ah.

You wrote unity? :P

Wardy

No its my engine code running on top of unity obviously

lol

I wish i could claim i wrote unity

Aidan Mueller

Haha.

Well I wouldn't find it that cool since it's not FOSS.

But then again it would still be kind of cool.

Wardy

7:20 PM

I wrote my own "clone" of the System.Threading.Tasks stuff, just need to get this planet stuff using it now

then i can scale up to earth sized planets

Aidan Mueller

Whatever you do, don't put unrealistic orbits into the game.

Wardy

right now im just doing this to load test the voxel engine code

Aidan Mueller

I hate it when planets are like right next to each other and aren't falling into each other.

Wardy

to see how far itll stretch

Aidan Mueller

Or when planets on the outside are going faster than planets on the inside.

Wardy

7:22 PM

yeh lol ... my plan is that i wont be making that sort of game

this is really just about having an engine that can handle this if others want it

Aidan Mueller

Ah.

Wardy

my game plan is based around floating islands

planets make a good base

can gen then deform them in to "asteroid like" shapes

essentially what i need

Almo

@Wardy yeah, a planet that size doesn't have enough gravity to keep the water and atmosphere.

:)

looks very nice though :D

Wardy

my aim is to have it ready to go with a set of scripts that would support a "real" solar system

so if you want to build a space game you can grab my package in unity and just drop a new game object on the scene then drop a solar system component on that

job done

then off you go building your game in that solar system

because its all voxel based too the plan is to have some sort of storage system and server based saving if need be

i'm thinking if i use minecraft style file formats then the 2 could be compatible

data could be swapped between them

just a thought at the moment though

no final decisions made yet

Aidan Mueller

I would make it format agnostic.

Wardy

7:28 PM

well you have to choose a format at some point to drop the data to storage

but there's no reason why i couldn't offer up an API for saving the data

that way others can plug in their own storage providers

Almo

7:46 PM

hahaha

fuckingblocksyntax.com

if that's blocked due to url profanity:

goshdarnblocksyntax.com

I need to remember that site, if I ever come across needing to use blocks, I'm sure I'll not know how to format those declarations

Ali.S

@Wardy is it generated in real time?

Wardy

yup

Ali.S

I mean only the surface texture (the only thing that can be seen)

then you are on the right track ;)

Wardy

takes about 3 seconds to render a planet with a diameter of roughly 0.5km

Aidan Mueller

Not every frame though, right?

Wardy

7:54 PM

no that's just the initial data gen process

and building the base mesh

Aidan Mueller

OK :)

Wardy

the plan is to thread the process to gain more speed

so i can get that sort of time on say a planet roughly 5km in diameter

might not be possible but worst case you spend the 5 seconds up front to gen the side your are looking at then gen the rest whilst the game is running

Jovito

@AidanMueller So using pygame.Mask didn't work.

Wardy

hmmm making big planets may be a problem ... there are limits to the texture size i can give to unity shaders

Aidan Mueller

Use multiple textures?

Wardy

8:06 PM

yeh i wondered how i might do that, im thinking the problem will go away when i sort out the meshing problem

right now the planet is just a texture splatted on a unity sphere object

I need to gen the sphere myself

tht way i can chunk it

Jon

you just need to render the surface

no need to render the core

Wardy

that's all im rendering jon

but a planet the size of say ... the moon

has a diamter of 4km

Jovito

@AidanMueller I moved on to another idea now. I need to be able to set the color of all pixels on the circumference every time the radius increases.

Wardy

so assuming 4km = 4k x 4k in texture size to generate the heightmap data ... bang!

Jovito

Couldn't understand how the Midpoint algorithm works yet tho.

Wardy

8:10 PM

so it would prob be best to split in to max 2k x 2k sections

I currently have a bug in my cartesian to spherical coord converter method

its spitting out normalised values that basic always sit in the top right quad from what i can tell

If i fix that i should be able to get my own mesh gen building the planet mesh

Jovito

Midpoint circle algorithm

In computer graphics, the midpoint circle algorithm is an algorithm used to determine the points needed for drawing a circle. Bresenham's circle algorithm is derived from the midpoint circle algorithm. The algorithm can be generalized to conic sections. The algorithm is related to work by Pitteway and Van Aken. == Algorithm == The objective of the algorithm is to find a path through the pixel grid using pixels which are as close as possible to solutions of . At each step, the path is extended by choosing the adjacent pixel which satisfies but maximizes . Since the candidate pixels are adjacent...

So would anyone care to try and explain this to me? I really want to get this done.

Wardy

@Jovito lol im doing the same thing in 3d

pi r2 is your friend :)

you might find it easier to do it the way I'm doing it @Jovito

Jovito

Another problem is that the radius could increase by more than 1 on the next frame, and I don't know if pygame would be able to do it fast enough.

Wardy

given a point and a distance you can fill an array with values that determine if they are inside or out of the circle

its a voxel algo in 2d

Ali.S

8:44 PM

@Jovito that algorithm is pretty fast

way faster than what you can imagine :P

well I'm not so sure about modern architecture but it was so in the old one

the idea is simple

you start from one of circle points

lets say the top one

and move to the left

you know as long as you reach the 45deg, 'y' will always be greater than 'x'

William 'MindWorX' Mariager

Is there a simple way to find out how many cores my pixelshader/fragmentshader has available? I'm trying to explain how a GPU is more efficient at the same operation over lots of data.

I figure comparing 2-8 cores of my CPU with the number of cores on my GPU would show this nicely.

Ali.S

also you know, changes of x is more rapid compared to changes of 'y'

William 'MindWorX' Mariager

I have 1152 CUDA cores, but I'm not sure that's the same.

Ali.S

so you keep increasing x,

Jovito

@Ali.S isn't it the opposite? y changes faster than x?

Ali.S

8:46 PM

depends

on the start point

I've started from top of the circle towards right

so you just keep increasing x

and whenever you ran out of circle (by checking 'x^2+y^2 > r^2') you have to decrease y by one

Icy Defiance

@William'MindWorX'Mariager it's basically the same. very basically. CUDA cores have different abilities than the AMD equivalent, and both have different abilities than CPU cores. but the basic concept of "it does the calculations, and 10 of them do 10x the calculations," that much is accurate.

William 'MindWorX' Mariager

Yeah.

Ali.S

@Jovito not now

Jovito

@Ali.S k :/

Ali.S

i'm mid game right now

Jovito

8:54 PM

Q: Is XNA still relevant?

I am currently devlopping a game with XNA. But the community seems to not be active anymore. That's why I am asking if I should still go on... What's the advantage of using Unity3D ? Will I be able to use skinned models and custom shaders with it ?

if random numbers are important to you, checking out this page may help you:

pcg-random.org

OMGtechy

now I want to write my own

Oliver Schöning

I have just started using sin() and cos() for some vector movement..
I'm not getting it right yet.. This sorta works:

var radians = this.angle/Math.PI*180;

    this.x += this.velX * Math.sin( radians );
    this.y += this.velY * Math.cos( radians );

But the angle just seems random o_o

jsfiddle.net/790438jv/5

I guess coz its "+=" and not "=".

OMGtechy

doubt that, setting the x and y wouldn't make sense. you need to mutate it

as you are

Oliver Schöning

ups

I want to find out how to make some simple consistent movement at the angles. 0, 90, 75 whatever should stay the same direction :D

OMGtechy

@OliverSchöning you need to divide by 180, not multiply

var radians =  -((this.angle - 180) * (Math.PI / 180));

Ali.S

9:37 PM

@Jovito so we won

OMGtechy

that works for me @OliverSchöning

Oliver Schöning

@OMGtechy it works! Thank you! I wish I wasnt so stupid :D But I'll learn it eventually.

OMGtechy

@OliverSchöning No probs, I didn't have a clue, I can just harness Google like a boss

Oliver Schöning

haha niice

OMGtechy

Knowing how to use Google gives people the impression you know a lot. People at work are astounded that I seem to know everything about every language, but I just look it up...

One day they'll twig.

Oliver Schöning

9:40 PM

Hehe :p Well it helped me a lot. I get a grip on this stuff soon enough

OMGtechy

The only languages I actually know anything notable about are C++, C# and Python

Oh and Sacul, but I wrote it so that doesn't count.

Oliver Schöning

U wrote a language :p ?

Is it on github?

SpartanDonut

Great news everyone. Finally got miracast working. Can stream audio / video from my PC to the TV.

There is some latency for gaming. I wouldn't want to play Street Fighter on it but playing Sonic Generations was very playable.

OMGtechy

@Almo not true

unless you designed it that way

Almo

Like I want to use Interface Builder in Xcode

that's going to be Obj-C or Swift

I want to use Cocos2D

that's Obj-C or Swift

OMGtechy

9:51 PM

And? You can compile to another language

Almo

yeah I really want to fuck with that

OMGtechy

The first compiler I wrote for this compiled to Python 3

Ali.S

@almo I don't like ObjC

Almo

@Ali.S I like ObjC

Ali.S

well, there is something wrong with you :P

OMGtechy

9:52 PM

Aside from that though, many languages allow you to call C code

so you might be able to do something similar

Almo

it's just easier for me to use what I have

OMGtechy

How boring

:P

SpartanDonut

How productive and pleasant*

Almo

I don't find Obj-C keeps me from doing what I want to do, so I don't see that writing my own language will make anything easier for me

Hey Everyone!

I been learning python

I come up with these cool mini games ideas I could make with Pygame

But everytime I realize I could do it better and easily with JavaScript and Canvas instead

Such a sad life >.>

Chris

@Almo those were zany games back in the day, I remember them being very weird but fun, funky music and stuff

OMGtechy

@TheMuffinCoder write it anyway :D

TheMuffinCoder

@OMGtechy But the problem is

OMGtechy

Nothing wrong with Python

Almo

10:54 PM

yeah the first game was great because it was so not like anything else

the second was asked to be more a standard platformer, so I lost interest in it

TheMuffinCoder

If I wanted my friends to play it they would need to download it

Almo

didn't play III

(Xbox exclusive)

OMGtechy

@TheMuffinCoder umm, yes, and?

TheMuffinCoder

But if I made it in JavaScript I could just make a jsfiddle

Almo

they're going back to the first game's design for this one

OMGtechy

10:54 PM

@TheMuffinCoder you can make standalone executables from Python code

TheMuffinCoder

xD I wish that was good enough

Almo

^^

TheMuffinCoder

But I think they wouldnt do it

OMGtechy

@TheMuffinCoder they would not need to download Python or anything, just an executable file and that's it

TheMuffinCoder

But I will do it still!

OMGtechy

10:55 PM

in other words, your game, that's it

TheMuffinCoder

I'll just rewrite it in JavaScript afterwards

OMGtechy

write it in Haxe? :P

TheMuffinCoder

:P I dont want to learn Haxe

It was to improve my Python skillz

OMGtechy

do it then :P

TheMuffinCoder

I see a lot of job opportunities with Python :D

Hey I could even post my mini game to the pygame website

OMGtechy

10:59 PM

@TheMuffinCoder doesn't matter too much, company I work for hired me to work in Python mostly even though I knew almost none at the time
