is there a reason you want to cache?

Grey

performance reasons I'd say right?

Almo

Unity docs say to cache references to components on gameobjects

so we're doing that

but is it relevant for transform?

Alex M.

I always sort of did it involuntarily but never for transform

let me see

Grey

@Almo i'd say no

Alex M.

Consider the expression:

transform.position = Vector3.zero;
The "transform" getter is hiding a GetComponent() side-effect and the "position" getter is hiding matrix-transformation side-effects. Yet, this is the syntax encouraged by the documentation and tutorials, even though it's suboptimal for per-frame computation.

All the other component accessor variables (listed here) will incur a GetComponent lookup, and are worth caching. Other than that, I wouldn't say that the setting .position cost is "hidden" as such, because you're setting the world position rather than the .localPosition so it's inevitably going to have to work this out in relation to its parent.

unity3d.com/support/documentation/ScriptReference/…

answers.unity3d.com/questions/9893/…

yes, caching does help

it's the same with colliders

Grey

8:05 PM

is almo using it per-frame

Alex M.

there's one collider per gameobject, but this.collider does perform a lookup

Almo

this.transform seems to go to GetInternalTransform while you can see the other ones do go to a lookup

I guess it doesn't hurt to cache it, so we may as well

Alex M.

I'd explore the internals but I uninstalled unity :D

Almo

:D

Grey

@AlexM. !!!!!!!!!!!111

clutches chest and falls to ground

Hnngggggggggg

No shame. Unity sux.

Alex M.

8:07 PM

no

I use it too much at work

Grey

no

Alex M.

seeing Unity at home makes me want to puke

Almo

hahahahahah

edit that to say "Seeing Unity at home..."

so I can star it

Alex M.

lol

Almo

thanks :D

Alex M.

8:09 PM

I hope I didn't piss off my software engineering prof

he made a snotty remark at a student for not knowing who Tarkovsky was

Grey

@AlexM. who is he

HUAEHUAEUHEHU

Alex M.

and then I said that maybe he knows who the Strugatskis were

and he kinda lost his smile

Grey

and threw his projectile across the room

because I was there too

in the back row of the lecture hall @AlexM.

lol

My bio prof is arrogant and snotty too.

knows his stuff, but his personality is meh'

Alex M.

also my networking prof is a mac guy

so naturally I showed him my assignment on my iPad mini

lol you can play football with it

Almo

awesome math thing:

A: Examples of mathematical results discovered "late"

This proof of the irrationality of $\sqrt 2$ appears to have been discovered in 1892 by A.P. Kiselev: If $\sqrt2$ is rational, let $\triangle ABO$ be the smallest possible isosceles right triangle whose sides are integers. Construct $CD$ perpendicular to $AO$ with $AC = AB$. $\triangle OCD$ ...

if you can work through and understand that (pretty simple) proof, it's really cool

shouldn't take more than a few minutes to understand

well, I'm a geometry hound

maybe more than "a few" but it's pretty cool

VMs are a really nice invention

it's like having an infinite amount of PCs in your PC

I'm thinking about dropping this one

so far it's 10% reflections on the craft of programming

Anyone know how you emit an unmanaged function call in .NET? :P

M Davies

Good question.

I don't know the answer.

game industry breaks in 1 day

gamasutra.com/view/news/212506/…

Jack Tretton, president and CEO of Sony Computer Entertainment America, is leaving Sony on March 31, 2014.

Alex M.

@William'MindWorX'Mariager lol

oh wow

as if Sony made games

Almo

they certainly seem to have input on games that get onto their PSN system.

Alex M.

yeah but to say the game industry breaks because something happens to sony is a bit extreme

Almo

8:54 PM

true

the game industry is hopelessly broken the day I quit making games AND quit playing them.

I love lots of types of games, and if there aren't any more that I want to play, something is wrong :)

Alex M.

lol

Grey

@AlexM. BROKEn

Almo

don't worry though; I can find one game to play for years and be happy.

Grey

BROKORO

@Almo most teenagers around my area are minecraft stir crazy

Almo

minecraft is pretty cool

Grey

8:56 PM

no

Almo

I don't have the time to invest in it, really

I suppose if I replaced LoL with it, I would, but I prefer competitive gaming

Grey

I played it for 2 months before I lost interest in it.

@Almo same

KAG,TF2, anything competitive

Alex M.

there was one time when I really enjoyed minecraft

I built this underground home and spa and whatever

you'd only be able to get in if you followed a stream of water in a very particular pattern

and somehow a creeper managed to fuck things up

I didn't know about peaceful mode

it felt as if I worked for nothing

and my interest dropped considerably

Q: Neder to not eat pizza

If I make a vow to not eat pizza, what can I not eat? On the one hand, it would seem that bread with sauce and cheese on it is called pizza, as that is what they give you in a pizza shop when you order a slice of pizza. However, it is implied otherwise in the bagel-bites commercial song: Pi...

Almo

hahah the fact that they have a term for satirical questions about what's acceptable in their religion is a good sign.

Alex M.

lol I want to open up a question there

"hi im jew can i eat sausage"

William 'MindWorX' Mariager

I found it!

And I made it fancy!

Needs some caching, but should speed up my reversing.

    public static T Invoke<T>(IntPtr address, params Object[] parameters)
    {
        var returnType = typeof(T);
        var paramTypes = parameters.Select(o => o.GetType()).ToArray();

        var method = new DynamicMethod("Invoke", typeof(UInt32), null, typeof(Program).Module);
        var il = method.GetILGenerator();
        il.Emit(OpCodes.Ldc_I4, (Int32)address);
        il.Emit(OpCodes.Conv_I);
        il.EmitCalli(OpCodes.Calli, CallingConvention.StdCall, typeof(UInt32), null);
        il.Emit(OpCodes.Ret);

Then I just make a fancy ExpandoObject and I can do some magic stuff.

Grey

OP CODES? r u workin with asm

William 'MindWorX' Mariager

That's IL actually. :P

Grey

9:21 PM

such intermediate

A: Some of the employees don't check if everything has been flushed properly and that the bowl is clean

Start using islamic law today. It is forbidden to not tidy your hands. Uncleanness (not looking unclean - but being unclean) is punished. For example in Singapur it is forbidden to spit or throw your bubble gum on the street. The prophet himself made a special hand washing, which is today used ...

The kind that cheats on you and then when you catch her she says it's your fault

Like, wtf.

Clean your shit up and get out of my face

Grey

lol

Almo

(removed)

hasherr

@Grey You remove too much stuff.

Almo

which is to say, "removed emphatically"

hasherr

It's like every other message.

I don't see how that even remotely warranted a removal.

That really bothers me.

I saw what you said already, but it's annoying to see people abusing such a simple resource.

Grey

9:59 PM

(removed)

I just posted a gif dude

nothing special. I don't want too many gifs in the chat

hasherr

0 sense.

Dont' abuse the button.

Grey

100 sense

@hasherr You can't abuse it

You can use it

rhymes

hasherr

You do abuse it though. Every other message is deleted.

Grey

Is hasherr nsa

Almo

maybe

hey alex

user4704

10:02 PM

There is definitely such a thing as abusing the ability to remove posts.

Almo

A Blue Has Spoken!

ok

Grey

@hasherr Using my detective skills

user4704

@Grey Then you shouldn't post them in the first place.

Alex M.

@Almo yes

hasherr is nsa

Almo

yeah i bet

Grey

10:03 PM

@JoshPetrie okay so what's wrong with removing them if I want someone to see it

and then I don't want it to be there anymore

Almo

wrong place

Grey

If you guys don't want people to abuse it, you should put a cool-down on it

user4704

Then DON'T POST THEM.

Almo

^

Grey

Lol

user4704

10:04 PM

@Grey I don't have control over the site software.

user4704

I do have control over whether or not you can talk in here.

Grey

Ban

Alex M.

hasherr is not abusing anything

he's just acting like a 15 year old

Almo

it was me :)

Alex M.

Almo is not abusing anything

hasherr

10:04 PM

@Almo I'm 16. Get your shit straight.

Alex M.

he's just acting like hasherr

Grey

So because I've removed one message in your presence your threatning to ban me?

Lol

Almo

you mean LoL

Alex M.

HoN is the new lol

Almo

and I don't think he was in fact threatening you in particular

Alex M.

10:05 PM

STALKER is roflmao

user4704

@Grey No, I'm saying that if you continue to abuse the privledge to remove chat messages you will lose it in the only way I can action at the moment.

user4704

If you want to post a bunch of images only for one person to see, then start a new room with that person.

Grey

Okay. Then what is the correct usage of the remove button

hasherr

facepalm

Grey

lol

Alex M.

10:06 PM

the correct usage of the remove button can be seen when I'm removing my messages

Almo

but anyone can join a new room

Alex M.

to prevent flagging

user4704

To remove messages that legitimately don't belong here, for example, because they were (intentionally or not) offensive or inappropriate.

Almo

Maybe we could see your tirade coming and "preflag your venting" :D

Grey

gotcha. I have no more questions.

Almo

10:06 PM

get it? prevent flagging. preflag venting

hahahahaha

user4704

I see what you did there.

Grey

mod saw what u did @almo

Alex M.

for deleted messages there should be a contextual menu option saying "This message was posted by Alex M"

so that the deleted message can be seen

and flagged

Grey

Lol

Almo

Delta Kappa Epsilon (ΔΚΕ; also pronounced D-K-E or "Deke") is one of the oldest North American fraternities with 52 active chapters in the United States and Canada. Delta Kappa Epsilon was founded at Yale College in 1844 by 15 men of the sophomore class disaffected by the existing houses on campus. They established a fellowship "where the candidate most favored was he who combined in the most equal proportions the gentleman, the scholar, and the jolly good fellow." Since then Delta Kappa Epsilon has produced five presidents of the United States (more than any other fraternity), has had it...

I still don't understand the point of this

Stallman recommends not owning a mobile phone,[90] as he believes the tracking of cell phones creates harmful privacy issues.[91] Also, Stallman avoids use of a key card to enter the building where his office is.[43] Such a system would track doors entered and times. For personal reasons, he generally does not actively browse the web from his computer; rather,

he uses wget and reads the fetched pages from his e-mail mailbox, claiming to limit direct access via browsers to a few sites such as his own or those related to his work with GNU and the FSF.

I think stallman is downright weird
