welcome to office hours with Prem.
We're gonna go ahead and get started by answering any
questions that already exist in the prime time questions threat.
There are none right there. So, uh, unimaginable silence.
I guess if you have any questions, drop them in the office hours, text chat.
I'm sure someone will mention something that causes
me to go on a random tangent about,
I don't know, sticks, bins, recycling or whatever at some point,
but until then,
Hello. So there we go. That's the perfect example. Um, a question that I will ask to,
uh, give me a second while I cough.
That will cause, uh, a, um
uh, you know, tangent. So, like,
mine is asked, What is something you, uh,
knew you have learned not related to computers or VR or anything like that?
Uh,
it was something. I'm certain that there was something
after you go out for a while and we go on to the, uh,
the second question that we have in the thread, which is from draus.
Who asks anything new in the past week going on.
Multiple new things have occur in the past week.
Uh, statistically,
quite a lot of new births have occurred in the world of sort of babies and
animals and creatures and insects and stuff. Um,
yeah. There's quite a lot of new things there.
I'm sure. Um, many new products have rolled off the line as well.
Like, the iPhone factories have probably created several new iPhones.
So, yeah, quite a lot of new things have occurred in the past week.
You have to answer questions like,
uh, directly with me
simply because, like, you know, I'm on the air. I I've got, like, you know,
got to keep things moving. So, like, you know,
Curtis has updated their question to to more.
They've asked more specifically anything new with,
like, new Project. And you need things that you have found.
OK,
um,
no.
So think us since you know, streaming code RT RT MP,
H
HSL and Web RTC. Have you heard about our
new streaming tech called S RT?
It's really cool. Low
C 0.97 millis
of frame over four G and doesn't need high bandwidth and no quality degradation.
Artefact of feasibility of how useful the
is I
never actually like learned much about, like the video code
and how they worked.
I am aware of S RT. I haven't tried it yet, though, Um,
O BS just merged something. I can't remember what it was was, though.
Let me look at a couple of areas that I can take a look at. Where am I? Lost
Whip. Yes, Whip.
They emerged whip recently.
I didn't really have a chance to look at what Whip was, but, uh,
O BS now supports whip.
I don't know what that is.
The case We have a question here from,
uh uh,
sorry.
I'm still sick, so I'm pronouncing stuff weird and all sorts.
Um,
could you talk a little bit about how
parenting objects affects your ability to move them?
The Children, that is, I've noticed some really odd things.
Try to rotate them, cause them to be skewed and would like to understand them better.
OK, so that's usually when non
uniform scale happens.
Um, when you do any transforms, you got to remember that,
like all of the slots transforms above,
like in the parenting hierarchy above it, affect that transform.
So a perfect example here might be, um,
you know, if you have an arrow that points
one way and you parent it to an object that is rotated 100 and 80 degrees.
It's gonna point the other way.
Even though you don't attempt it, you need it to or don't intend it to.
To get it to point in the correct direction again,
you have to do another transformation to that arrow
to get it pointing back to the correct direction.
That usually isn't too much of an issue. Um,
but when you start adding non
uniform scale in, um,
the mathematics just ends up working in a way where
you end up with just absolutely horrific stuff happening.
Luckily, I have a guide on a YouTube channel relating to non
uniform scaling.
Um, I plead with people to not use non
uniform scaling as much as possible.
Um,
but
people do that all the time.
There was actually two videos on the topic. Had to be pleading.
Uh, the second one here is more like stuff. I notice people doing
like if you want a cylinder, for example,
uh,
rather than than people making a cylinder and editing the cylinders properties.
I've seen them edit the scale that the cylinder is on, which
almost always calls uniform scaling because they want a cylinder, That is is, uh,
um,
not as tall as the default cylinder.
And it's just like, please don't do that with non uniform scaling.
That is the worst way to do it.
So there we go. Is that, um, question done?
Uh, Mr Square Peg says,
how would I use animated billboard sprites instead of a 3D model for my avatar?
I don't really know why you'd want to do that,
but you can totally do that with just a material setup.
Um, I did a partic
thingy
recently that I believe is basically billboard. So So try that. That one
here.
But I don't really know why you'd want to do that.
Um, billboards basically face the user, um, through, like,
rendering tricks rather than mathematical tricks,
Um, and
can be really useful for things like particles.
But I don't really know why I need to use the one on the avatars. I mean,
if you had, you know, fire or whatever coming off your avatar. Great.
But that would just be a particle system on your avatars. I. I don't really know.
Uh,
no, we can't apply that millisecond or later.
So, like, um, video, audio and, like, data channels have got, like,
different compression and, like protocol schemes, et cetera,
um, I think S RT would be appropriate.
O asks, What's your favourite operating system?
So I have an issue with the word favourite. Right? Um, this is going to be a mild thing.
Um,
I don't really have favourites. It's it's kind of annoying. Um, it's not your fault.
It's my fault for being weird. Um, but like,
you know,
uh, the way I view my computer is it's like a place that I get shit done on.
And so, like, the operating system needs to be one that just gets out of my way.
And
that has always been windows. But it isn't because Windows is my favourite.
Like, ideally, I'd run Linux, but,
like I did run Linux like as a main driver for a long time a while ago,
I just like, you know,
let's install some in video drivers. Oh, wait.
Let's just, you know,
like stab yourself in the eye instead of installing those drivers,
because that's how
much of a pain it is to get that working.
Um,
and it just got to the point where I was spending more time maintaining the
computer than actually using the computer or
like deciding what to maintain the computer.
For example, it was like, Oh, I'm on Linux so I can
decide what my terminal them
is. You know,
you'll look at all like the the
developer YouTube channels or the developer streamers.
And they've got, like, really complex terminals with, like,
all these like graphics and crap.
And I'm just like, I just need it to work.
I just need it to work, you know,
when it's 3 a.m. and your business client is ringing you and like there's a problem,
blah, blah, blah, blah, blah, blah you need, like,
as little steps as possible to get, um,
to get through.
Um,
here I have I have found a video I wish to link
regarding favourites.
Uh, OK, let me just double check.
I haven't missed anything before my videos, OK, after the videos,
I try very hard. Well, ask this is sort of an update.
I try hard to the actual mesh before I touch scale.
The other solution is simply pull them out of the parent group and into the root.
Do the thing put them back in.
Yeah, that that works.
Uh,
another thing which is is you'll see it in some
of the primitives that are created in the great new menu
is if you separate functional from visual.
Um, so you'll see, like things like the the light,
um, that's created by the light tip has a visual slot.
And then everything under the visual slot is just
everything that makes the light have a visual,
usually that light bull.
But everything above that is components which make, like, function.
And therefore you've got two hierarchies basically within the same object.
You've got one that deals with,
um, how it looks and you've got one that deals with,
like how it works and that can also work with things like grabbable.
Um, receiver. Surface is right.
If you have a visual slot, you could non uniform scale a cylinder,
and they're absolutely fine.
But then the actual, um, gravel receiver surface could be a uniform
cylinder collider above that visual slot, so that works out Well.
I think you asked about Adam
again. Yeah. Um,
when it's fixed, I I'll make a tutorial for it.
There's a few bugs that exist and they need to be fixed.
Let's take a look at Virtuals now.
So Virgil says, How do you How do you multiply multiplex?
An audio source, such as from an audio clip player or the voice audio stream.
I want to make a soundboard that can play
voice lines but also temporarily reduce the audio sources.
Replace the audio sources on my vis
and my audio output.
Uh, reference multiplexer I audio source would probably do that.
Um, quite well, one of the things that you need to keep an eye on there is that, um,
if you're using the reference multiplexer,
um, you won't have the built in stuff that keeps the asset loaded,
so therefore you should use an asset
duplex. But asset multiplexes won't allow you to do audio sources.
It's tricky,
but reference multiplexes seems to be the best
bet right now for that particular scenario.
Uh,
reality says hello. Did I miss anything? Yes.
You miss precisely 13 minutes of content.
They'll be on the recording, which will be uploaded shortly after this.
Virgil asks. How does the image component work?
I've seen it in the mute helper and I have no idea what it is or what it does.
That's probably the U I
one. So, uh, if you'd like to there is a 13 or 14. I can't remember.
Um, part tutorial series on UIX
that I have created. Um, I think one of them the tree is called images and sprites.
So I'll go ahead and
link that one to you, and that one should deal with how the image component works.
Right. Uh, next, uh, think asks, is cheese a quantity?
Uh, I don't know. Oh,
here comes the tangent. I knew someone would make a tangent, right.
Uh,
I don't really know why this came up.
I think it was one of the sort of commentary channels.
Um,
there is a guy who does like lectures on
YouTube that are not scientifically accurate at all,
but he thinks that they are,
and so you can just watch them and just be like, What the hell are you talking about?
And I remember watching one of these late at night,
and it was just fascinating how wrong this guy could be.
Um, he started off with positing that one plus one equals one.
Um,
that then turned into
like one plus one, equals infinity.
He was doing this all with, like maths and humongous whiteboard,
drawings and all sorts.
And then he started talking about the East and West magnetic poles.
I'm just like, Oh, OK.
But throughout his story and his lecture,
um,
he's in what looks to be like just a room in his house,
and he's got wooden flooring and he's shuffling
around a bit like adjusting his weight.
But the floor is like
creaking and making all sorts of noises,
and he keeps walking backwards and forwards from the whiteboard.
It's it's very, very confusing, but he always says stuff like,
I showed this maths to like a room full
of mathematicians and they had no answers for me.
It's like what
he's like.
Yes, and I used to be in the Army,
and they're they're hiding the secret of maths from you,
and it's like what the hell? But,
um, it did lead to an interesting thought that I occurred with me, which is again,
and I ask people, sometimes this because it's just designed to be like think bigger,
right?
Was maths, invented or discovered,
and then is maths useful by itself. Or is maths just a measurement tool?
What I mean by that is when you say one plus one equals two,
it's usually a quantity of one.
Plus another quantity of one equals two.
And if you can reason that you're maybe adding the same things together.
So let's say one drop of water, plus one drop of water equals two drops of water.
Then you could actually argue that.
No, it is actually just one, but it's a different measurement, right?
So one drop of water plus one drop of water.
The drops will combine together into a unified
collection of water, which is a new quantity, but it's still one unit of water.
And that, I think, was his his like his reasoning, It doesn't make any sense.
But, like you could tell that like
you could understand how someone might get there.
Maybe
if he has some questions,
we'll go back to hypothetical questions about the nature of reality in a moment.
Um
uh,
G asks, How often do you play near yourself?
Um, not a lot right now, Um, particularly if I'm sick.
I sort of stay awake until I feel feverish enough to lie down again,
and I go back to bed.
Um, that's that's cool.
Um,
but usually quite a lot.
I usually just make shit posts right now, though, um,
if you go to my public folder and look at Memes,
you'll you'll see all sorts of stuff when I say memes like people think like stuff
that they might know about stuff that might be on my know your meme or whatever.
No, I mean memes that exist in my own head.
Yeah. I try and operate when I have, like, cold and flu stuff.
I just try and operate, like, if nothing's wrong. And the reason is because, like,
if I'm actually ill and I cannot,
like, get to my computer, that's it. That's ill. I can still move around.
Life is just a little bit painful. Um,
I'm gonna try and find out
what
that's better.
Uh, I'm gonna try and find this YouTube guy. Um,
it would like be in my YouTube history.
But, like,
uh, I watched that months ago. Found it. Yeah, I remember. Um
Oh,
that's why I watched his video. Because his name is Nigel Cheese?
Yes. His name is Nigel Cheese.
Yes.
Alright, let me let me get back on the on the train now. I found that
here it is. I promise. You'll just literally be like what
I
watched like,
uh, I watched. I don't know, like 20 minutes of it.
I was just like, OK, I could see how you have come to these conclusions,
but they're wrong.
But I can see how you've got there.
Yes, yes, si man down. This man thinks he's clever. Yes, exactly, Nigel.
Hand like Nigel cheese. It's It's
it is a beautiful video. The one I linked is the full lecture.
But, um, many content creators have done, um,
sort of debunking or reactions to that.
Um,
but yeah, he talks about
all sorts of things that don't make any sense.
Let's not be weird about his actual appearance.
Um, he looks like a stereotypical professor. I don't think he looks like an
you know,
his ideas might be weird, but I'm sure he has motive behind him having those ideas.
Um, Virgil posted a gif, um, showing a unit circle and the various, uh,
uh, equations that define that circle.
If a math teacher had ever shown that to me in maths class,
I probably would have understand trigger
a lot better.
Um, I, I learned maths, uh, with a teacher just sort of vaguely yelling.
She had this voice that
sort of half yelling half not,
um purely on whiteboards.
It was incredibly boring, and I didn't really remember any of it.
But then I relearned maths with, like, digital animations,
and and that was much better because I couldn't understand everything.
Virgil says you cannot deny his face is very red. That's a lighting problem.
He's got all sorts of problems there. Like framing lighting, focus all sorts.
But, uh, yeah, um,
I think he is now talking about overhead projectors. OK, overhead projectors.
No one can read anything.
You write on an overhead projector like,
I don't mind the overhead projector where they've got, like, a print
sheet
that's got information on it, because that's usually clear.
What I hated is when someone used an overhead
projector and then wrote on the projector slide in like
the felt tip pen where each letter sort of merged into another one,
and then they would accidentally smear it.
No one can read any of that. Stop doing it.
Yeah, overhead projector. There it is.
If anyone has not seen one of those during their schooling,
you are younger than me.
I hated those.
Although I think it was me not being able to read one
of those that led to my first visit to an eye doctor
where I got a prescription for
it. Because, you know,
I did want to make, uh, in
one of those. Um,
yes.
I wanted to make one of these for a laugh. Um, like a VHS trolley.
Where every time someone asked a question that was solved in one of my videos,
it would just appear and roll into stage and start playing.
I think we've talked about this before,
but we're gonna go ahead and talk about it again.
Uh, whenever those, um, VHS trolleys rolled in.
Sometimes we played, um,
these UK TV shows, which were very,
very well produced.
Fever, dreams of craziness.
So I'm gonna say a few words now and I'm gonna hope that people, uh,
know what I'm talking about
Through the dragon's eye.
Does anyone know through the dragon's eye?
If you're British,
you probably know through the dragon's eye I will
get you the opening to through the dragon's eye
because through the dragon's eye,
it was an amazing TV show exclusively shown on VHS troys.
Um, there was it was a company called look and read and look and read had
various shows that were made, um, with the general
principle of trying to teach people to look and read.
But
the shows were always so off the wall that
it was just
crazy
through the dragon's eye Badger girl. I didn't see badger girl dark towers. Yep.
The legend of the lost keys. Yep, yep. Earth warp. Oh, God, yeah.
I couldn't like Ah, I'm gonna like I'm gonna have to get all of these
and we have to get all of these, put them somewhere,
and we're gonna We're gonna have a We're gonna have a look and read.
Now it's It's gonna be amazing.
What was Earth warp about?
Earth was about pollution. I remember that one now. Yeah,
bad
girl.
I remember the legend of the Lost Keys being really
weird because they had outfits that didn't make any sense.
Let me get some legend of the lost key outfits.
Yep, yep.
Oh, my God. The outfits were so strange.
I'll get back to Nia's questions once the first these two pictures over with.
So Legend of the Lost Keys, um, I'll give you, like, a brief synopsis of both of them.
Legends of the lost keys was, um uh, a
family sort of inherited through, uh, you know, sons and sons etcetera, uh,
keys that would allow you to go to a kingdom.
And that kingdom was sort of authoritarian or militaristic,
and and they wanted to conquer Earth.
So the key keepers, guardians of the keys,
whatever they were called were meant to protect that portal.
But, um, in the series, they they made a mess of the portal and
that the people came in
and invaded or something. I don't remember
through the dragon's eye was a bunch of school students
painted a mural at their school of a dragon.
The dragon came alive, breathed fire on them.
And then they woke up in Dragon Land, and
they had to reconstruct the Dragon Corp. Which kept the Dragon land together.
The dragon cop had a really cool name and, uh, various pieces of it.
It basically looked like foam play tiles that they needed to reassemble uh,
there was
They had really
automata
names. Like
if
boot or something. I don't remember
that were one colour, like, completely one colour.
Their hair was pink, their face was pink,
their clothing was pink and they would follow around.
One of them had a magic baseball bat. I'm not making this up. You can go watch it.
Uh, OK, Back to questions. Virgil, Ask when are we getting ready? Body be physics?
Uh, we don't have an ETA for that particular feature.
Do check the github for any updates to that. Apologies.
I can't give you any, um, logical noises about it.
Uh, Nitra has posted a link of those benches. Yes, those benches were fantastic.
Except when they got old.
I remember sliding along one of those benches that was quite old,
and I ended up with a bunch of splinters that were
both in the shorts that I was wearing and my butt
do not slide on old versions of those benches.
Uh,
asked what's the topic for today? There is no topic. You can ask whatever
question you have.
I will randomly talk about UK TV shows and various other things. The
calamity Lima says
asset server been acting up.
You can take a look at announcements for an update on that one.
Uh,
I think it says what Sucked was sitting on the end with the white nubs that stuck out.
Yeah,
I seem to remember that we had, um We have school kids.
Give us some slack that we had some sort of like
we call people gay who sat on the nubs.
It it was it was a thing.
We were school kids.
Yeah. Typical typical typical
typical school kids style thing. Yeah,
well, it's even more. Um,
I guess,
concerning looking back on it is for the first couple of years of elementary school,
we did PE class in our underwear,
like usually a shirt and underwear, but, like, you know,
no actual shorts or I think that was weird.
That was the nineties, though. World was different.
Uh,
as I think I mentioned sitting on the on the
floor crosslegged I have not done that in a while.
Um, but every time I do it, I regret it. Just like my my knees hurt. Help.
Uh, Calamity Lime asked. What's my favourite doctor? Who?
I'm gonna repost a video about favourites.
Um, I posted before really want to watch most of these look and read shows. Now
there's so much lost media and
there's so much lost media and I want I want
to watch multiple shows that are lost media related.
Um, and if you want, I can talk for endless hours about lost media that I want to watch.
I'm gonna double check. I haven't missed any questions.
Dre sauce, Which cheese is my least favourite? Um,
no, not gonna answer cheese questions,
but I think I've got all the other questions. Virgil asks what does
mean?
Uh,
I was in a video about this, but then I just didn't get around to it.
And now I'm sick, so I'll do it once. I'm not sick or whatever, but,
um,
F, uh,
stands for fear, uncertainty and doubt.
But
I wish that, uh, just generically the community would not use it.
I'm not gonna say, like, what types of community. I just wish no one would use it.
And the reason is because when they people say fud,
what they actually mean is trolling.
If you remember trolling from the early Internet days,
there is a difference between someone who has fear,
uncertainty and doubt about an application
and someone who is trolling to instil fear, uncertainty and doubt.
The second one, where someone is trying to instil fear, uncertainty and doubt,
is the one that crypto channels usually want people to avoid.
But because they call it flooding
it, it just
it sounds like they're not doing their job.
It's fear.
If there is fear about a product,
it is your responsibility as a product owner or a member
of the team for a product to combat that fear,
uncertainty.
If there is uncertainty about a product,
then it is your responsibility as a member
of that product's team to combat that uncertainty.
If there is doubt about your product,
it is your responsibility as a member of the products team to get rid of that doubt.
So we shouldn't use the term fud. We should just
dispel the fud that exists,
And then we should return to using trolling because there is trolling.
So a good example might be brand new user. You've never seen them before.
They are completely new to neos.
They waltz into the telegram and they say,
How do I know that Neos is going to be successful. I have doubts about NEOs success.
They are not trolling.
They are not Ban.
They are asking an honest question that you guys should do your best to answer,
to illustrate that you have the community's best interests at heart.
But instead it's like Ban for fun.
Now, the opposite of that might be someone who has been in the community for years,
absolutely years and just goes.
I heard that that
was dead.
That's trolling. That's not Fuding that's trolling.
There's a difference.
Occasionally I'll I'll use the phrase precision of language,
which is sourced from a film called The Giver Precision
of language is very important in terms like that.
You know,
uh, if it's legitimate Fudd from a new user, they shouldn't be banned.
If it's someone that's trolling, call it trolling and ban them
by calling it Fud
was basically saying, like, Hey,
no one can have any sort of doubts or any negative opinions about the product at all.
And if you look how that works in like any any big
company that's actually successful rather than
whatever crypto product that isn't successful,
they always have fun,
like right Now there are people all over
Facebook posting about how Facebook is terrible.
They don't get banned.
But there you go. That is what Fud is.
And I gave you two answers. What? One? Which is you know what
crypto people think it is. And one which is what it actually is.
There we go. We are at time.
So if there's several people that are typing have questions, go for it.
Otherwise I will go ahead and close things off. I'm hungry.
I should probably like, go get a covid test from the store. Just double check.
Yeah, I'll go grab a covid test. I'll get some snacks in, and, um,
yeah,
I will wear a mask. Um, I will. I absolutely wear a mask. I won't eat the covid test. Um,
they're not edible, usually.
I mean, technically, everything's edible, but I wouldn't suggest it,
but yeah, I don't see any additional questions coming in.
If you have any additional questions,
please drop me on the questions and help channel or direct message me
etcetera. I will get back to you when I can.
This recording will be up when I can process it, which is getting faster these days,
it's still not automated, but
I'm sick, so we'll just do it the manual way, which is a few questions,
and I will speak to you guys later.
