All language subtitles for 39. Adding a Wizard Enemy

Let's create a new enemy type

To add some variety to the game

But also to provide us with the ability to increase the difficulty as

Game goes on

So once we implement this enemy type were going to

2

Amend our enemy manager so that it starts spawning the new anime type

As we get into the game

So go ahead and go to York any assets your child

And let's open up tilemap pack

Hairlicious take a look and see what enemies we want to introduce now

We probably should use an enemy that is slightly different than the right

So I'm thinking either

The spider or the dark wizard here I think the dark wizard would be

Find Dad

So let's choose

This guy right here

I'm going to go to the individual tiles directory and I'm going to scroll down until I

Find him

There's the wizard

Ok so that wizard is tile 011

1.png

Win a drag that over into the file system in Cadell

And I'm going to rename this to

Wizard

Underscore

Ok and then under scenes

And then game object

Let's create a new folder under

And call it wizard

Underscore Enemy At The End just to be

Consistent with the basic enemy that we've got

Drag that wizard png into that wizard

Just like so

And then hit control and

Make it route type of military

Going to call this wizard

Anime

Then go ahead and save that with control as

Inside of scenes

Game ABT

Wizard enemy

Alright lads had control a and search for Sprite 2D we're going bad is right to die

Which is going to have a texture of The Wizard

Png

And then

Go to the office

Why

Hold control

And let's offset

That

Bye

Holding the left Mouse button down and outfield

And moving the mouse to the left

And an officer of -8 in white put the origin

Of the Sprite ad

The fee

So that's going to be good for our purposes

And then let's go ahead and institute of child seeing we want to instantiate

The health

And let me go to the basic enemy seem so ctrl shift o

Search for basic enemy

This health component is

The default

At 10

In so what I'm going to do is I'm going to

Pampers maxol at maybe do something like

Animal it's just write 30

And I move his health component up to be the first child

So I set the max health to be

30

And then let's go head in Standish

The death component underneath this

I move that below the health component

And then I dragged the health component node into that health compare

Property

An Ender Dragon sprite

Into the Dead

Spray

Ok so we need to look at our basic enemy we also need to add a hurtbox compose

And

And we need to make this wizard anime a based

Of character body to die

So

We made a mistake here

And that's fine

Because what we can do as we can right click on the root note

And then we can say change type

And then we can

The character body 2D

And our issue is fixed

So you can always change the root type if you want

Ok so now we need to add a collision shape which represents

The shape that will collide with the train

And in our ship resource let's create a new circle

And lead set the radius down of that to something like 6 by clicking into that circle

An access 24

Yes and then

I'm going to hit w on the keyboard and just drive this up until the bottom of the circle

Is just touching the origin just like that

Ok

Click on the wizard anime l modified

The

Collision layers in the collision

So we don't want us to exist on a layer something uncheck that layer bit right there

Animal leave masks at 21

Which is the train

Leia

Ok let's instantiated another child seen in going to call this

Perkbox components

Instantiate a hurtbox component

And then

I'm going to put this above that collision shape 2D and then I'm going to add as a child another

Shape 2D

Just like so

And then we're going to cream

Again another circle shape

Let's move this hurt backs can't

By selecting

Sitting w on the keyboard

And then dragging clicking and dragging this

Into roughly the centre of the wizard

And I'm going back to the heart box compare

Collision

Opening of the shape resource

What's at the

Radius to 8

Yeah I think that's going

Just

Fine

So let's go back to a basic enemy and let's open up the script and see what kind of b

We have a very basic behaviour set

I'm here

Which is basically just moving towards a player at a

Givenchy

Rather than duplicated code I'm going to show you how we can

Make our movement code

Genera

And we're actually going to create another component for this

So let's take control in

And if that's not working it's probably because

You have

The Script editor

Contact

So always make sure that

One of these panels is in context

By clicking

Before you hit ctrl n

Anna let's Create the root type of

Note

And it's called this velocity

And I'm gonna go kind of fast food this but I am go

Wayne

What I'm doing to the best of my ability so

Let's

Go

And save this in our scenes

Component directory alongside of our other components

And I'm going out Ace

Default parameters are ok

We're going to create an export variable export via

Max underscore speed

And this is going to be of type

Result of

OK then let's

Create a

Function

Funk

Move

And it's going to accept an argument of caribou

And then that's going to be uptight

Character

Ok and say what we're going to do is we're just gonna right past right here

Because we need to keep track of a variable

Simon save our

Lhasa

Is eager

Vector2

0

Let's Create

Another function in here

I'm going to call it accelerate

In Direction

And our Direction is going to be

Type

2

That's right path

So the way that we're going to use it

Is we're going to be able to manipulate this internal velocity by cooling Accelerate indirect

And then we're going to be able to move the character by calling the smooth

Now why is

Is this good well if I go back to my basic enemies

Hear what I can do

Essentially is I can

Manipulate the velocity and comoving slide

From within

This

Component here

So I don't have to keep doing

The same code over and over again

Also going to

Prove our ability to control

How enemies move

By utilising this accelerate

Now we'll probably also going to want another function so let's stop this out I'm going to create another function call

Bank accelerate

2

Claire

Endless pass in

Well we'll keep

So what does keep no arguments

Ok so the first thing that we want to do

Is we want to say

The Folly

We want to say in our acceleration Direction

Scrap our desired velocity

And what is are desirable

It's going to be the direction

That were passing into the funk

X

Power maths

Speed

Right so this is the final velocity that we want

Tube

Then what we're going to do is we are going to

Accelerate

The current velocity

That desire

So what we can do

This we can say

Velocity

Remember this is our internal velocity

Is equal to

Velocity

Start

Look up and we want to live

Which is linear interpolate 2 / 4

I'm not going to use that framerate independent that we talk to you

So this is going to be 1 -

And then this is going to be some smoothing value so we'll say

What's a neg

Acceleration

X

And then we can use this

Get process

Ok so they don't want to break down

Before I break this down

Let's Create another export variable

Blow the man

Speed and call it via acceleration

And put a float

Ok so now alright should go away

So what do we do

Were using the linear interpolate which again

Take away

Which is what we're calculating here

And says I want to go this percent of the way

Sward

This

Supplied

So we're going to essentially go from my current velocity

To the desired velocity

This person

Everything

Now if we were to put something

Point one in here

We would say every frame

Ten percent

Closer

To the desirable

Now this is

10% according to the current

So you may notice if you're familiar with mass

Subtitled by

We compress knowledge for you!

This is essentially an asymptote

Basically what's going to happen is it

Get 10% closer to your goal

Every frame

You're actually going to a pro

But never reach the desired velocity now in practical terms that Jacqueline

The case but in mathematics

Dad's

Insole

We don't want to provide a fixed value girl

10%

And the reason is because if you have a user running at 400 frames per

They're going to be going 10% closer to their goal every single frame

Rainbow

And if you have a user

Playing at 10 frames per second we hope that

Happen but if you have another player

Going at 10 frames per sec

They are going to arrive at the goal match Slough

Right it's all because

There can be different framerate

We want to

Introduced an early release

And basically we do

Is we take 1 -

And I like to use x

Energy

The only reason I'm using that is because it provides a

What about moral and natural feel too

And then we're supplying a

A power to raise

To which is

Some smoothing

Which is our negative

Get-process deltatime

I'm here

Will give you the value of Delta that is typically passed into

The process function here

This Delta

This Delta

Are going to be the same

As long as they are

Run

In the

Ok let's apply

Or supply whether a default acceleration value by giving it -5

Anna let's say them

Speed is equal to

14 actually sorry this is not supposed to be negative here that

5 because we're not getting it

SO53 acceleration and max speed of 40

As a

And you can see all these defaults appear now

My inspector be careful

Calculator.net

And then in our move function

Working a pass in a character body that we want to move and it's actually going to do is going to say

Character body

Velocity is equal to velocity

Then we can call

Character body

Darton

Moving slide

And then we need to re assign our Velocity

So that we can

Say update

The character bodies last Eso

Breaking this down

We're assigning the CO2 by blasty to articulated velocity

That's internally stored here

Were telling the truth about it to move and slide and again moving slide

Returns the remaining velocity after

Collision and then

Because that happening internal

The character body

What is not being updated in our Velocity

We just simply reassign our current velocity

To whatever the character body

Is after moving slow

Celtic

Doesn't collide with anything at removing slide

Then

These this last should be the same as the

Hopefully that all makes sense

And then let's do one final one which is accelerate

Two player

So what we going to do is going to say

Bar

What's a owner no to die

Is equal to owner as no Genie

And then we're going to say

Owner node 2D is

Then we're just going to return

Function

And the reason were driving the owner as a note to die is because we want to do the follow

We want to say

We want to grab the players position solovar player is equal to get 3

Get first node in

Claire

Claire is equal to null will just return

Ok and now we can calculate our directions save our Direction

Is equal to now remember when you want to calculate Direction into vector some track

But

The vector that you were

The point tour

Goes

So this could be player.dat global position

-

Moana

No Judy make sure to you

Owner no today

Global position

And we want to normalise this song

We're going to

Apprentice eyes that operation in then called that

Normal eye

And remember that the reason that we want a normalize a vector is because it returns a

Unit vector a vector of

One or mag

Sufferance

If I want to make a line

Pointing in a certain Direction

If I multiply that by a vector

Hasn't

2 then I'll actually end up with

And I don't want that so normalisation make sure that my vector my Direction

Has a length of 1 so that when I do multiplication operations on

It returns the result that I'm

So we normalise that and then we're going to do

Call Accelerate in Direction

With

Supplied

So this is essentially a helper function that would just look into

This funk

I'm here to update

Ok so we've got our belasi component build out

Before we go back to her

Let's

Go to our first and we that we created

Let's instantiated veloci

Drag it up

Around the default values here should be fine so that's good

So it's open a bar basic anime

Script here

We don't need this anymore so instead we're going to grab a reference to

That velocity components so already far

Velocity component is equal to

Elastic

And then in the process method we can simply call

Lastly compound

Dart xcelerate

And then what was this called this was called Accelerate to play

So that's what we're going to call in r

Crypto accelerator

Player

Ok

And then we can call velocity

Component that move and I'm passing the self because this is

So now we should be able to remove

These

Free call

And we can also remove this

And by the way there's no longer I need to have a rash

Health component in the sky

So what's going on remove

As well

Ok so we've simplify down at two lines and that's not really the strength

Pulling a Sandra of last week about the strangers

Now we can control the max speed and the acceleration

And we can make a wildly different numbers for different enemy types

And we have a nice or component that we can further extend with more functionality

That can then be you

Everywhere

So in order to make sure that we did everything correctly let's just Run the game and make sure that our rat enemy

Is still work

It's not

And I think I have a typo

Display align lives type that as known to die

And then let's remove this normalize and we should be

Ok

So it's called dot normalized with a d

So the typing is used for

Because

My player global position was not tight

And so good dog cannot

Give me hints about

What function I can call her

Because I didn't recognise this first

Piece of the subtraction as a no

But adding this as no 2D to the

Telescope

That's what it is and then

Everything is good so let's go ahead and Run the game again

And my enemy should still be moving now what your notice is Dad

The enemies now or a lot slower

Turn

And that's because we have an acceleration

Before we were just telling the enemy to go at max speed

In the direction that we said to go

And that made it like under the player much harder but watch what

If I go to my basic enemy here in I change my acceleration

Like .5 instead

What you going to see is at the enemies are very slow to read

To the

Exposition

So I can run past this

Look how long it takes for that enemy to change Direction at

Right

So the cool thing about this is that we can actually achieve

Prequel

Enemy behaviour

Buy just tweaking me stupid

So I can keep it .5

Turn the max speed up to 100 if I want

And then what

So now I've got all these enemies

Lying around now look these actually kind of feel like flying enemies

So we might use this combination of numbers

To make

Flying enemies to make it appear like

You know they have to fight against the air in a decanter return around that quick

You know it gives them some weight

And of course we can also turn the acceleration up a bunch

To essentially make them instantly respond

2

The changes in the player Direction like this enemies

Borderline under

So anyway

With just these two parameters I'm going to reset those by the

8 to 40 and 5 again

Was just us to parameters we can actually create a wide variety of

Any movement behave

And all it takes is just a c

Prescription

Ok

So with that detour and done let's go back to our wizard enemy

And let's go ahead and instantiate

Velocity component in the Wizard and I

Below the health campaign

And let's set the wizards max speed

To maybe something

Maybe something a little bit heart maybe

6

For the max speed

LS20 acceleration down to something

Now that this is we can go our main seem open up the enemy manager here

What's going on

That scene

This basic enemy seem right here we're going to have to change all of this

I'm just going to drag

My wizard anime scene on today

First

And then go ahead and run it and see how they were

And the nice thing about this is that

We should be able to see what the enemy looks like so the enemies not me

And the reason that is not moving is because we have

Add Script To The my so it spawn incorrect

Let's go out back door weather in

Add a script to the route no

Let's create an override of

Process

And I'll try pass in there for now

A couple on ready variables and I want you to think what do we need to do

In order to make the enemy move

What how do we vote

We do need a grab

Reference to the last

So let's go out and do

Bar Brasserie komponen

I would encourage you

Also too

Think ahead

About what we do

Try to you know even pause the video for a second

And just try to anticipate

What were going to be doing now

Because if you are

Only just doing everything that I say to do

You may find out less effective than trying to predict

What I'm go

Just we'll tip for you

Cheeky Panda

Anyway let's go ahead and go further

Elastic component disease

To you

Velocity

And Annie trick you can do as you can grab a note

With the mouse click and hold and drag

And if you drop the load in here It just gives you the short hand wrap

Let's do it in the sky

But if you start dragging it

And then you hit control

Hold control and then release

It would generate an on readystate

Oreo

So we can do that to be a little bit quicker now so I can say the last

Important

First

Then hold control

And there's are ballistic

Neat little trick that you can keep in mind

The process method what do we want to do

We want to say velocity component xcelerate

2

Claire

Ok and then we can save the last

Component

Rightmove

Cell

Let's go to our basic enemies

And let's copy this

Just like so

So there's move sign

Black radio

Bring a back over to the wizard anime script

Is that in there now if we really wanted to we could make another component for this

But I'm fine with just copy and pasting it everywhere

Ok let's create a new note under the wizard anime core

Note

Diesel into the Note 3

And then

Call this visuals and put it below the death component

And then drag the Sprite to the as a child of that

Note

And then let's go ahead

Created on ready reference to this by clicking and dragging the visual

Then holding control then dropping it

Get some now all of that should be worth

If we go back to our first basic

We can remove this get direction to player

Keeping the code clean is important because it's very easy for cold to come out

No you're not

That these scripts are essential for the same

And it may be tempting

2

Just create one script for the enemy there

Is this content

But I would caution you and

Doing that because then it becomes very hard

To create specific enemy behaviour

Which we might do

This is essentially a copy paste from the basic enemy however

We don't want to share scripts necessarily

Because that's going to be really

Limit our ability to

Implement unique enemy

So when the course is done you can feel free to consolidate these but

Let's keep them separate for

Ok so now it's Run the game Remember our enemy manager is spawning a wizard

And look at that

Ok so we have a couple of problems the wizard is bunching up on itself and it's facing the wrong direction so this is a copy paste

This is a great example of what I'm talking about

This

Visual scale

Move sign needs to be actually different than the basic anime.so

Remove the negative

From the Move sign in there

And that will fix it

And then we need to go to a route now here and change the layer that the enemy

And the layer we want

Is able

5 or sorry

4anime

So we don't want to exist on the train later but we do want the wizard to exist on the enemy collision

So that he collides with other enemies and doesn't Bunch up

Additionally we need to set the mass

To that as

So that it also

Oxford collisions on

Ok let's go back to a basic anime and we can see in the snow

Tab here in groups we need to add the wizard to the enemy group

Well so there's a lot of setup to do that we need to remember

Let's go to a wizard anime go to the new tab got a group

Right

Enemy in this

Text boxes in Annan

Just a little bit more said to go on this wizard we needed you two more things so the hurtbox component here needs are

France to the health camp

So that's good and rank the health component down

Intern

And then we need it in Stand should a child scene we need to instantiate a vile

I'm going to put that

Above here as well

Let's attach the health component to the cell component property as well so drag their health and put it over

Or this time I'm going to

A sign and double click the whole component

And then the drop percent

Let's make the wizard drops

.5

And let's go to a basic enemy here

And turn down the volume

This one too

30

5%

Right now it's Run the game and we should be able to kill a wizard so let's go ahead and see

If we can do so

And you should notice that

Our death

Component is working flawlessly

With that

So now we have

Free death animations

For every type of enemy by just building that

Component

Alright our wizard enemy has been implemented the next step is to make it so that

Game can spawn different types of Venom

As the game
