00:00:06,210 --> 00:00:08,480

Hello everyone and welcome back to class.



2

00:00:08,490 --> 00:00:11,060

Mark Price here at Dove slopes dot com.



3

00:00:11,070 --> 00:00:16,500

And what we've done so far is we have got our pop overview controller with the scene view in it and



4

00:00:16,500 --> 00:00:20,780

we are loading the half pipe into it and we placed it and scaled it cetera.



5

00:00:21,000 --> 00:00:24,080

And what we want to do in this video is get the other ones in there.



6

00:00:24,120 --> 00:00:27,090

So let's go ahead and do that now we know we've got a half pipe.



7

00:00:27,120 --> 00:00:27,850

We have a pyramid.



8

00:00:27,870 --> 00:00:29,710

And we have the quarter pipe.



9

00:00:29,840 --> 00:00:30,120

OK.



10

00:00:30,130 --> 00:00:31,800

So let's do the pyramid.



11

00:00:31,800 --> 00:00:36,440

Next we're going to say let.



12

00:00:36,990 --> 00:00:42,940

Well what we just kind of use the ready we should actually change the name around a little bit.



13

00:00:43,050 --> 00:00:47,770

Let's call this pipe and call this pipe.



14

00:00:47,810 --> 00:00:48,770

Here we go.



15

00:00:49,080 --> 00:01:01,450

And then we're going to say let pyramid equals the unseen named Art see an asset slash pyramid pyramid.



16

00:01:01,500 --> 00:01:03,890

DA which is what we've named it.



17

00:01:04,470 --> 00:01:08,830

And then we got that note again.



18

00:01:09,690 --> 00:01:15,550

Maybe we should do is change this to VAR's and reuse them.



19

00:01:15,630 --> 00:01:17,410

That's even better.



20

00:01:17,740 --> 00:01:18,830

A little bit of refactoring.



21

00:01:18,840 --> 00:01:21,630

No big deal no big deal at all.



22

00:01:21,630 --> 00:01:24,120

And let's just back to J.



23

00:01:26,240 --> 00:01:31,260

Avoir or B.J. Inbar note and now we can do is just reuse them.



24

00:01:31,270 --> 00:01:33,450

So B.J. equals this.



25

00:01:33,720 --> 00:01:34,090

OK.



26

00:01:34,180 --> 00:01:43,750

Say a. equals OPG root node child node with name.



27

00:01:43,750 --> 00:01:46,790

We're going to say pyramid recursively true.



28

00:01:46,800 --> 00:01:53,860

Now if you're wondering hey Mark why are you overwriting your object here won't that replace it in the



29

00:01:53,860 --> 00:01:54,390

scene.



30

00:01:54,390 --> 00:01:55,340

Well no.



31

00:01:55,860 --> 00:02:00,900

And here's the reason why it's this line of code right here once you've created the node and we've grabbed



32

00:02:00,900 --> 00:02:03,620

it we added as a child node of the scene.



33

00:02:03,620 --> 00:02:06,840

So now the child node is holding reference to that.



34

00:02:06,870 --> 00:02:12,180

And so even if we delete this reference here with a new object it's not going replace the object that's



35

00:02:12,330 --> 00:02:15,330

being held by the by the scene itself.



36

00:02:15,330 --> 00:02:19,260

So by this line of code here by adding it to another object or adding a child note that now contains



37

00:02:19,260 --> 00:02:24,150

a reference to the old object which means we're safe to get rid of this object we've been using here



38

00:02:24,360 --> 00:02:25,700

and replace it with the pyramid.



39

00:02:25,890 --> 00:02:33,210

So just one of those things like a little thing that could be very confusing or cause a bug and you



40

00:02:33,210 --> 00:02:36,600

have to kind of understand code and references and how that works.



41

00:02:36,600 --> 00:02:41,630

So we got our we got our object we got our node.



42

00:02:41,880 --> 00:02:46,020

The next thing we want to do is set the scale and the position of the pyramid.



43

00:02:46,020 --> 00:02:56,550

So we're inside no doubt scale can be equal to A C and vector 3 make and zero point zero zero three



44

00:02:56,550 --> 00:03:01,770

to zero point zero zero three to zero point zero zero three cheerly.



45

00:03:01,770 --> 00:03:03,420

These are numbers that worked for me before.



46

00:03:03,420 --> 00:03:05,590

We may have to adjust which is OK.



47

00:03:05,940 --> 00:03:10,650

Node position equals C-n vector 3 make.



48

00:03:10,720 --> 00:03:19,290

And we're going to say negative zero point nine five negative zero point nine and negative 1 and we



49

00:03:19,290 --> 00:03:24,140

may have to adjust that as well too and then seen the root node.



50

00:03:24,420 --> 00:03:33,990

Add child node and we're going to say node like so cool and then move this preferred content size command



51

00:03:34,050 --> 00:03:34,690

x.



52

00:03:34,920 --> 00:03:38,230

And let's just put it right here



53

00:03:41,470 --> 00:03:42,000

OK.



54

00:03:42,290 --> 00:03:44,650

Let's see if this works let's run it on the simulator



55

00:03:48,250 --> 00:03:50,160

so that iPhone 7 you go



56

00:03:53,880 --> 00:03:54,540

in we're running.



57

00:03:54,580 --> 00:03:58,570

It's click that hit an invisible icon here and fix it eventually.



58

00:03:58,570 --> 00:03:58,860

OK.



59

00:03:58,870 --> 00:04:03,460

So we've got this ramp way up here and then we got this little guy right here it's way too small.



60

00:04:03,460 --> 00:04:08,220

We're going to fix it and we're going to want to move it up more towards the middle which is OK.



61

00:04:08,530 --> 00:04:09,450

No big deal.



62

00:04:09,460 --> 00:04:11,450

So bigger and a little higher up.



63

00:04:11,470 --> 00:04:20,910

So instead of 3:2 Let's go ahead and say I want to say 5 to 5 2 and 5 2.



64

00:04:21,120 --> 00:04:22,150

Let's do the size first.



65

00:04:22,210 --> 00:04:23,530

Run it again.



66

00:04:23,640 --> 00:04:28,490

I want to do the size first before I start messing with position so I can make sure that it's in it's



67

00:04:28,870 --> 00:04:32,150

we can adjust accordingly.



68

00:04:32,590 --> 00:04:33,600

A little bit bigger.



69

00:04:33,670 --> 00:04:38,730

I'm going to say 5 8 5 8 and 5 8



70

00:04:50,430 --> 00:04:51,790

perfect that's a good size.



71

00:04:51,960 --> 00:04:52,290

OK.



72

00:04:52,320 --> 00:04:53,450

It's not centered though.



73

00:04:53,550 --> 00:05:01,550

So we'll just say on the X let's do negative 1 and give it a shot.



74

00:05:08,750 --> 00:05:09,680

Cool.



75

00:05:09,770 --> 00:05:10,830

That looks great on the center.



76

00:05:10,850 --> 00:05:11,960

Now let's bring it up a little bit.



77

00:05:11,960 --> 00:05:12,820

It's too low.



78

00:05:12,920 --> 00:05:13,660

Just a little bit.



79

00:05:13,670 --> 00:05:16,590

So we're at negative nine.



80

00:05:16,820 --> 00:05:19,970

So let's say negative.



81

00:05:20,010 --> 00:05:23,010

That's interesting is so far down negative seven Let's try that.



82

00:05:25,840 --> 00:05:27,280

One negative 0.7



83

00:05:33,010 --> 00:05:36,430

and a little bit higher and say six 5



84

00:05:46,010 --> 00:05:49,300

wonderful I think that looks good and we can move it up later if we need to.



85

00:05:49,300 --> 00:05:50,700

So we've got the half pipe.



86

00:05:50,870 --> 00:05:54,800

We have the pyramid and now we just need to get our quarter pipe.



87

00:05:54,920 --> 00:05:56,430

No big deal.



88

00:05:56,510 --> 00:06:15,770

So B.J. equals as seen named Art and assets slash quarter DHP and Noad equals Jay Root node child node



89

00:06:16,810 --> 00:06:21,690

with name Korder recursively true.



90

00:06:22,190 --> 00:06:25,530

And then we'll set the scale and the position of the quarter pipe.



91

00:06:25,610 --> 00:06:37,850

So let's say No dot scale is equal to s c and vector make and what we have here.



92

00:06:37,890 --> 00:06:40,390

We've got four quarter Piatt.



93

00:06:40,490 --> 00:06:50,720

We're gonna say I'm going to do the same number as the twins appear 0 0 5 8 and zero point 0 0 5 8 and



94

00:06:50,800 --> 00:06:54,100

0 0 0 5 8.



95

00:06:54,150 --> 00:07:03,770

And that looks good and we're going to say no position equals CN vector 3 make and scroll is up here



96

00:07:03,770 --> 00:07:04,820

for you.



97

00:07:05,470 --> 00:07:07,340

And what we want to do for a position.



98

00:07:07,370 --> 00:07:09,900

We want to say negative 1.



99

00:07:10,310 --> 00:07:22,540

And then for this position so we know that going lower in these numbers brings it.



100

00:07:22,770 --> 00:07:24,860

What does it do it brings it downwards.



101

00:07:24,900 --> 00:07:26,020

Well actually no.



102

00:07:26,040 --> 00:07:29,520

Point seven is way up there at the top So yeah it's going to bring it down so we want to make this even



103

00:07:29,520 --> 00:07:33,590

more so in our in our positioning here.



104

00:07:33,590 --> 00:07:36,290

So let's say what.



105

00:07:36,630 --> 00:07:39,290

Zero negative zero point nine.



106

00:07:39,330 --> 00:07:46,290

Make it even lower and then we say negative 1 and then we're going to say seen the root node taught



107

00:07:46,490 --> 00:07:50,410

at child node and we're guessing note.



108

00:07:51,060 --> 00:07:56,590

So let's run it and see if we got lucky and it worked in the very first try.



109

00:07:58,010 --> 00:08:06,300

At least that it got in the right spot for us.



110

00:08:06,330 --> 00:08:06,810

All right.



111

00:08:07,050 --> 00:08:08,630

So it's not low enough for sure.



112

00:08:08,700 --> 00:08:09,980

The size is good though.



113

00:08:10,080 --> 00:08:11,820

I really like the size.



114

00:08:11,820 --> 00:08:15,040

So I just want to bring it even lower.



115

00:08:15,740 --> 00:08:18,270

It's interesting that it's putting it in the same spot.



116

00:08:19,550 --> 00:08:21,880

Point nine Why would that be in the same spot.



117

00:08:21,920 --> 00:08:22,790

X 9.



118

00:08:22,790 --> 00:08:26,730

I'm not really sure let's say negative 2.



119

00:08:27,230 --> 00:08:30,000

Just to see what happens.



120

00:08:30,100 --> 00:08:30,940

A big change



121

00:08:42,900 --> 00:08:43,900

it's a negative too.



122

00:08:43,920 --> 00:08:46,760

Got it there but not quite where we want it.



123

00:08:47,250 --> 00:09:07,670

So let's go a little bit lower and say negative 2.6 rerun it.



124

00:09:07,760 --> 00:09:10,730

It's a little too low let's say 2.5.



125

00:09:10,880 --> 00:09:15,830

And I think what we're going to need to do is bring up the pyramid a little bit more so negative six



126

00:09:15,830 --> 00:09:19,610

point three.



127

00:09:20,070 --> 00:09:20,750

Let's run it.



128

00:09:33,230 --> 00:09:36,290

A little bit better.



129

00:09:36,520 --> 00:09:45,780

And one of the pyramid up and moved the quarter pipe up pyramid is going to go to say 6 0 and quarter



130

00:09:45,780 --> 00:09:55,800

pipes going to go to two point two for a run it just testing it out trial on air.



131

00:09:55,880 --> 00:10:02,330

Maybe you're wondering hey Mark White Why didn't you just write an algorithm to make a grid and place



132

00:10:02,330 --> 00:10:03,800

the objects in the grid.



133

00:10:03,830 --> 00:10:10,640

And like I said I could have done that but the math is quite extensive in order to detect how big the



134

00:10:10,640 --> 00:10:16,630

screen is and make things Project perfectly across the screen in a grid system in the 3-D view.



135

00:10:16,730 --> 00:10:21,140

I would probably have done this in Spryte kit before I went and did it here in 3D and then just use



136

00:10:21,140 --> 00:10:22,430

2D images here.



137

00:10:22,490 --> 00:10:24,140

This is quite perfect where I want thanks.



138

00:10:24,140 --> 00:10:30,710

I just want the pyramid up even more so we are going to say point five on the pyramid and there's only



139

00:10:30,710 --> 00:10:37,340

three objects so I felt like it was reasonable just to place them here than to spend a whole hour coming



140

00:10:37,340 --> 00:10:41,640

up with an algorithm to put these in a grid.



141

00:10:41,990 --> 00:10:43,090

Just a decision.



142

00:10:43,130 --> 00:10:45,680

So it was a little bit higher.



143

00:10:45,680 --> 00:10:50,360

We're almost there ladies and gentlemen we say point four five.



144

00:10:50,420 --> 00:10:52,090

Run it again a little bit higher up



145

00:11:03,210 --> 00:11:04,560

click the secret button.



146

00:11:06,540 --> 00:11:07,940

And I'm going to work with this.



147

00:11:07,950 --> 00:11:09,320

This is good enough for me.



148

00:11:09,330 --> 00:11:14,040

So we're going to call this video done we've gotten three three objects here.



149

00:11:14,040 --> 00:11:16,690

It looks good and placed here strategically.



150

00:11:16,770 --> 00:11:23,950

So we can tap them and then place them on the market screen on this on the A-R a view.



151

00:11:24,060 --> 00:11:28,260

And this is cool so we're going to call this video done and the next video we're going to get these



152

00:11:28,260 --> 00:11:29,040

rotating.



153

00:11:29,040 --> 00:11:31,440

So they just have a little more life to them for working with 3-D.



154

00:11:31,440 --> 00:11:32,640

They might as well be moving.



155

00:11:32,640 --> 00:11:34,140

So that's it for now.



156

00:11:34,140 --> 00:11:35,580

Marc price at DEF slopes.



157

00:11:35,590 --> 00:11:37,840

Com see all soon.
