All language subtitles for 05. Game Camera

We've got a basic player and we've got

A basic

So let's get some camera movement working so we can actually

Traverse the

And be able to see what's going on

What I'm going to do is I'm going to create a new scene by going to see in new SIM

And we're gonna start using hotkeys now that we've done this a few times through the UI

So the hockey create new scenes is control

And that will automatically bring

To the new sim creation

Can you can hit control a

To bring up the add node dial

So again that's control End to start a new scene

And then control a

To open up the ad no dialogue

What I'm going to do is I'm going to search for camera too

And I'm going to enter

To add

To my

Scene

I want to rename this to game camera

And the recommended style for naming your nose by the way is Pascal case for

Good names and

Case for basic

Everything else

So we received

What's inseam

Create a new phone

Game underscore camera

And we're going to say that

Game camera

What's going on at a script

And we're going to keep the same thing that we have last time so no

Default for r temple

And then

The default

Is fine

So where can I go

Create that

So whatever you want to do it

Well every frame we need to update

The cameras

But first we need to tell good girl to use the curry

Camera so in Godot

You can have multiple cameras in a scene

In the camera that surrendered

Is based on what camera is the current camera

And so the way that were going to do that is there just going to in the ready method or reply

Bus pass line

Current

I was going to go and save

So when the camera is ready it will be made

To me the current camera

And then in process we want to follow the player now

How do we know

What the position of the player is within the game camera

What we can do as we can use groups for that

So I'm going to go back to my main

I'm gonna click into

Best player seen here

Click open in editor

The only thing that you can

Is you can hit control she

And then

To bring open the quick

Window and then you can search for your scene by name

And double click it

So your top players

If I click on

Root node and then go to the Note Tab

The inspector

Or wherever it is in your edit

There's a groups button here which

And now I can add the player to it

Try and manage groups if I'm

To do it this way

And I can type in here into this box

Player

And click

So I've got a player group config

And then I've got all these nodes that are

I want to add the route player no

To the player

By clicking the player note in

Snowden

In group

And then click

Add

Click ok

So why group guys is it essentially an identifier that can be accessed from anywhere

In the cold

We're going to be able to get

All the nodes in this player group in order to find

Aeroplane

I might go back to my game camera scene in open up the Script

By clicking the Script button

In our process method what we can do is working to replace this past line or going to say

Tree

Which gets the current steam train

Get nose

And then

Player

And then we can do as we can save our

Play nodes

No notice I said clear loads here and notice out this says get no

Group forget nose and group function return

Every note that exist in the playgroup

Which means that a return

Tenerife

But only interested in the first result

What can I do in if statement

Clear nose

Die

Size

Which of the funk

So checking the length of player now

Is greater than 0

Then we're going to put the Colin at the end in

Ingenious

What tabs are the way that blocks are the term

It's kind of white Python in that sense

So if statements need to have

All of the block indent

Functions need to have all their blocking

And so on and so forth

So far player knows that size is greater than 0

Then what we can do as we can say

Via player is equal to player mode

And then we can drop the index

And this is similar to other programming languages use the brackets

And then the index that

I want to get

So when we do it display

Well the simplest thing to do it as we can say after

Is equal to

Claire

Global

Position

Now you'll notice that you're not getting in tallaght sense here

When you

Two player dart global position

And the reason is

Godot does not know what the type of

Play it

We know that it's a no to die

That has global position

Qudos

The only thing that's returned from getting those in group is an array of a node

Justin

Because that's the bass type that all notes inherit

And so that's the safe way to return

All the nodes in a

So imagine

If I had in the players

Another note type that was like a control now

Or

Clean nose

I can have a mixture of nodes in this list that's Returned in this array data return

That

Do not have a global position

And so that's why it does not recommend

Global position here because it doesn't know what the exact

Now if you want

What you can do to get that intelligence is you can say

Since we know the type of

You can say I want to grab the first player note

As

A note

And so that's going a cast

Player variable

To type notes

And then we can say player that global position

See how we get all of our lord to the related

Please in our

Going to be using tights to heavily however

We will sometimes use it when it's convenient

For intelligence

You can

Fully type your gdscript using static type

That's not something I'm going to spend too much time doing in this course but just knows

You can use types everywhere

And actually I don't think we don't want this to be the opposite were just going to

The cameras global position

To be equal to

Can you play

What position offset is a property that you more so

To use for screen

Something to run this

And see if it works

And is not working

I think for a second why it's not working

If you answered because we haven't added the game camera to our main scene

Then you're right

This is going to happen all like when you're building your dog

If your new tikitail you'll be running your seen wondering why a change you made is not working

That's because we

Built the camera in isolation here

Lights on

Scene

We haven't added that seemed to our main

So let's go ahead instantiated childnet again

By right clicking on me

Instantiate child scene

And then

H camera

And I want to put the camera

The first child in the sea

This is one note that is not affected by draw order the game camera

Does not take to order in

A counter when it's rendering

So I just like to put it first so it's kind of out of the way

So now what

And now you can see

The camera is full

IPlayer

What's with the camera a little bit nicer by introducing smoothing to the camera

So most games your notice when you're playing

The camera is not

100%

To the player

Actually has a slight drag behind it

While you're moving

That's because

Most

Professionally made games have cameras

That are smooth

Which means that they don't

Just automatically set themselves to the position they actually have a little bit of travel

Which makes them feel a lot more now

We're going to do that is we're going to

Is framerate in

Dependant

So

We've got our camera script here so go ahead and open the car

Back up I'm going to do is at the top of the

Create a new variable

Target underscore position

And then you can is initialised

Two vector 2.0

Which is the constant for

SE2 0xn 0 Wykeham

Instead of setting the global position herein meaning

Order do instead is we're going to assign our target

Tool the player glow up

Ok and we're going to remove that line where

Set the global position

And now I'm going to do as I'm actually going to take this and terrible

Cut it out

Add a couple of new Lines

So the guitar recommended silent

Two new lines in between

Switch function

So that's why would you ring me

Call this a quiet

We're going to open and close parentheses and then put a corner

And paste our code in

And we're seeing an aerosol can

Passing the process for the air stop

And we need to

An extra line

What the proper spacing between

Acquire target is going to do

Is just going to assign

The target position but only

What's the player

Sonar process method

We're going to call

Just like

And so that's going update our target position everything

And then we're going to blow up position

Is equal to

Global position

And loop stands for

Linear interpolated

Linear interpolation if you're not

Familiar is basically having a star position in any position

In specifying a percentage

That represents the percent of the distance between those

To possess

So another word

If I have

Point a witch

10 pixels to the right

And point B which is at the origin

0

Then alert of 50%

Would return to me a position that is 5 pics

The percent that you pass into a linear interpolate represent

A point

Between the two supply

That is

The supply

Percent

Between

Hopefully that makes sense but you're going to see how it works

Real quick general make

So I'm going to learn from Cameron's current position

To the target position

And this is where our DELTIC

In a place so I can put something like .5

In here that's going to say is every frame

Move the camera

50% of the way

2

That's essentially just going to be stuck to the player because if you're games running at let's go 400

Basically after three frames it's going to be on top of the player

Add a player

Is not going to notice

Camera smoothing at all

This is why we're going

Framerate independent live

It's a way of doing lerping AKA

Smooth

That is independent of your favourite so I could run at 1000 frames per second and would still behave the same as of the

Where was running

At 10

The way that we do this is we take

1.0

Minor

And you can either

How

Here

And provide

A base

I like to use

Which is the natural x

Which actually gives

A very natural feeling smooth

So we take 1.0 -

In for a float we want to

The negative Delta

X

And we have some smoothing value so we're try 10

Bradford

Now

This mathworks

I'm going to attach resources

In this lesson with links

Explains the exact mathematics behind this

I just know that

This formula where you too

One point

The natural exponent

Which is a mathematical constant and then raised by some negative power

And that produces

Mouth that makes it

So again if that's not quite clear in the mouth and don't worry we're going to be using this sort of Formula 4 article

How to create smooth learning

Anna create a really nice

Feeling effects

What's going to run the game

And now you can see if you move around

That your camera is dragging behind the players

And when you stop

The camera takes a few frames

To Settle on the place

Position

Great

So that's it for this lesson with our camera done

We're going to move on to

Working on a basic enemy
