So what the heck are we looking at

I know it's confusing it's really not that confusing so basically what happened was

Unity

Put together a template for us

This is basically a c-sharp template this is how all of your script to go to start

When you create the

First

Appear when I get a worry too much about what's going on but these are just called namespaces

Honestly were just gonna scroll down I just ignore it for now

So this is really

The meat of our Sky

Basically what happening is

You're saying

There is a class or

Another way of thinking of it is there is a script

Dad public in will talk about what public and private mean

That's called player

This calling means it extends to the monobehaviour

The manor behaviour is basically

In layman's terms

The foundation or the root level

Of

What makes a unity script in unity c-sharp script

There's certain properties that we can use because we're extending

To the Manor behaviour

When I got way too much about it

I know that already that sounds confusing why is this a colon why is that green what's a monobehaviour

Why is the class blue

Used to all these Colours as you continue writing scripts and don't get too bogged

Down in the minute details right now

All you need to know is that unity created a script for us and that's script through this

Template in front of us

In that template basically said

Hey this is a script

Call Claire

And it is a monobehaviour

Can you tell me TVs curly brackets

Does an opening and closing bracket as well

The dad of lime here to show

Hey all of this is one set here and what is that set well it's the public class play

So this curly bracket is immediately going to start telling unity

Hey all of this continent here

Is part of the public class player

You let mine and make perfect sense but just bear with me when she keep going

Before we talk about what voidstar does in void update us explained

How unity read The Script

Pic of universe

Being here really

Fast speed reader

Is going to read using system start collections then is going to jump to using systems that collections that generic

He's going to move down to using unity engine

And then he's going to hit this

He was going to say ok

The something called a player

M&S going to hit this

Which is the star

In basically what this function does in unity this function through pretty much every c-sharp script you write

The very beginning working at tell unity

To do something the moment we hit the start button

Tell us about a quick script here

Don't get too in the weeds here just follow along as best you can

Debug

That log

Hello

And you'll see a red squiggly there that means we need to close out this

Sentence

Or

Statement

With a semicolon

I would say about the Script

And you're back in the universe

Wait for it to compile

Everything was good will have any errors being thrown in the console that's good

Now I want to do before we hit play

Is it gonna make sure we drag this script onto a game on

Search create

3D object

What's a ECU

Let's put it as 000

How to make sure camera is also a 0 position

-10 z-axis is good

You must be sure to rename rq player

I'm going to drag x

And as you can see the player script

Is on the inspector tab so now it's a component

I've player so we have the mesh filter of the mesh renderer

The box Collider and also the player script we just create

Square head in hip play

As you can see in the console window

We have

Printed the word hello in print is just a fancy word of saying display or right

So that's what this

Wirral line Deirdre debug.log

Hello

By the way too much have the same tax year just know that that was the point

Of this function start

Unity will read this and go ok I need to do something

When we start the unity player

Any me later read this and say you know what I'm gonna print hello in the console

Unity is never going to fire this function again ever

He's never going to do this again

It only happens when I seen loads

So that's the benefit of start

Wigan position the player here

We can spawn DayZ object

We can set the health to zero

We do all sorts of cool things the moment the game begins

Now the update function is pretty much

The opposite of what started is

Update says do this over and over and over again

60 frames per sec

Again ticket unity as a really fast speed reader

Once unity gets passed the start function

He continues to read down

He says

Here is an update function

I'm going to read this

Forever

And ever and ever at 60 frames per second

So he's going to read down it

Any backup

Again and again and again and again

The question is why on earth would we want to do that

Any engineers well that's how we actually have stuff happening in a game

To resemble we can move the position of the player

Every iteration

Search write a script to better understand what the update function is actually do

First begin to write a little comment here the way you comment in a script is

Two slashes

Move

Me to the right

One you

So there's a comment so now let's try and write a script that achieves that comment obviously

How to read a comment for every screen

But comments help you better understand what you're writing

To the way we do this is something like transform

That position

Equals

New vector3

1

0

Zara

And just remember

You want to end every statement with a semicolon

Theresa Lee

We cannot access the transformer components

My inspector

And we can access the position portion of that transform so that's transformed at position

And we're going to set it to

A vector3 in what a vector3 is basically a position

Acts of 1

Why is 0nz a 0

We had save jump back in the universe

The notice

We'll have any errors as go ahead in clear the console

That's it play and see what happens

Noticed that his position is now set to 1 so did exactly what we wanted it to whatever you wanted to have it

Move to the right

Over and over and over again currently

It's just been set to 1

It's not actually moving what the way we achieve this is when we move it

Over 1 unit relative to its previous position to the way we will do that is

Transform

That position x + 1

Search try and understand what this line actually means

Basically I want my position

2 equal

My current x position

Plus 1

What save this song

And see what happens

There goes

Zoom out really far here

Guess he's moving pretty fast

Now why is he continually doing

Well the reason why is if you jump into the Script what currently happening is

Unity is reading this line

Over

Andover

In over again

Why is he not reading this line well that's because he knows that the start function only happens once

The update function happens 60 frames per second

So

Every time he reads this line

He's going to move

Relative to his current x position

Plus 1

We just keeps going over and over

And over again

And that's what causes a player to move to the right

So that's why you use the update funk

Are you going to write a lot of script inside of the update function

This is where you spend the majority of your time writing scripts

Especially games

A lot of stuff happens within the update

Going to spend a lot of time

Inside of the update

So quick recap year just to clarify

Press the actually write script for a unity game we need to use these namespaces I cannot worry about him too much so

Just going down and we're going to declare

A public class called player

That extends to the monarch behaviour

Pretty much every script the right is going to extend to something

Most of them are gonna extend to the money behaviour

You really don't need understand anything more than that

Is a public class motorbike about public and private in the future

And unity is going to start reading the Script

The moment you hit play

He's going to restart and he's going to say you know what

I need to write hello into the console

I'm only going to do it once though because the start function only happens once

Is it immediately jump to the update

Function

Because he's constantly in this up

We're going to be able to do things inside this update over and over and over again

So transformed at position is going to equal my current position

Plus 1

Is going to have an over and over and over again

So hopefully that's clear

And we can move on to actually simplifying this line of code a little bit more

Instead of writing transform that position = the transformed up position that x

We can actually just put a plus right here

And then remove this

That is a match simple way of writing

Pretty much exactly what you just saw

Play The Night you gonna use plus equals all the time

A good way of thinking about plus equals is it basically is synonymous with advanced

Now to be clear though

This one unit is actually relative to the speed or the

Efficiency of the computer or console did the players on

So in order to ensure that were not moving at different rates across different frame rates on different computers

Anytime you're iterating like this anytime you're moving something at a speed

You always want to multiply

Bye time

Delta time

Basically that means one second

So we're gonna move it

1 unit

Because I'm a lemon I'm not going to tell you I know what this means I just know that the moment you multiply a number

X x at delta time

It means that the speed

Your object is moving

Or rotating or scaling whatever your iteration is

That speed is no longer dependant on the computer

Or the framerate

That is being you

But it's saviour

Go back in the unity and deploy

So now he's moving

How much lower

But that's ok

Are we going to do is maybe change the speed to what's a bye

It save
