When our experience bar fills up we need to be a

To be presented with an option to upgrade our abilities or require new build

And so that's what we're going to be starting in this life

So what we going to be using for our upgrade

Is custom resource

And where resource is it's essentially a file

That

Hoards a bind

Cedar

So the idea is that we're going to be able to create about these resources

And then manually add it

Some ass

So that resource

Within the Ed

That we can done reference in code

And so you'll see how that works

Let's get into it so first let's go to the resources directory under our file system

Let's create a new folder underneath that

And cold

Upgrades

Right-click on up

Selection new

And then resource

And these are all the research

Is that we can

Use if we wanted to

Now we're not going to come anywhere close to using all these resources

Subtitled by online-courses.club We compress knowledge for you!

But you'll notice that we've actually you

If you are red

Sovereign Saints under the sheep to eat we've already created a circle

Shape 2D

And a rectangle

So these are actually resources as well

We've also been using textures across or Sprite 2D

Which are another type of

So resources basically anything that holds some

Data that can be passed or

What we're going to do is there any creative cost

Resource so are we going to do is double click the root resource here

And that's just going to give us a plane resource

It's called this

What's called

Sword

Underscore rate

And save

And have you got your upgrades for you should see that that's alright is there and you can double click

To see

That it will open up an inspector

Now we actually have

Done anything with this resource as a very bare bones

Boil notice if there's a script section right here

So we can

Attach a

2DS resource

To make them work that way that way

Time to work

And so what I'm going to do is I'm going to create a new script under upgrade so right click up

Create new

Script in the Script dialogue we are going to rename this new script you were going to call

Ability

Upgrade

Dodgy

Mobility underscore upgrade

Dodgy

What's going on in creator

What's double click to open

Ok so we're going to want to change this first line here we're going to write extended

Resource instead because we're going to be attaching the script to a resource not a no

Export a couple

Tips for going

Do at Expo

Name

And then this is going to be a type of string

Nice to another x

Bar

Description

And this is also going to be another string

Let's do another export as well

And this is going to be a bar name what's a bar ID

Ok so I'm just going to leave that as it is and then I'm going to go over to my sword read.to yes I'm

Double-click that again

And I'm going to drag the ability upgrade into the Script

And as soon as I do that you can see that

We've now got those three properties that we can

And there's one thing we can do to make our description a little bit more out of the ball is we can actually do

Export underscore multiline

To tell her that it should be a big heading box so you can see now

In the ability upgrade igd

We can see

A big description box and then we can click this button to bring up

Full screen

Text Window

This is night if you're going to be riding a lot of

As is the case

Description so with our sword rate so I could weekend

Go ahead and

Felony feels so let's

You sore

Underscore rate for the ID

And then our name let's say

Sword quickness feel frida name this heavy one

What we're going to do is going to write a quick description so I'm going to say

Increases

Sore

A tag

What's the Sea by

10

Of course maybe will change that number later but what does give it up bass

Description

So

As the description States were going to be making the

Ability upgrades

Change the speed

Are the swords attack

The thing about this is that this can actually be stopped

As well so we can present this

Upgrade to the player multiple times

As a way of upgrading

Disorder even more

And one final thing that we're going to do is let's go back door ability upgrades

And let's just call

Classname

Class underscore name ability

Upgrade

That's going to help quite a bit in the future so we're just going to a site

Neck last name

And it looks like we're good girl alright so let's create a new note so go ahead and go over to your scene dark

Hit control pen

To start a new scene

And then make it a route to

Of a plane no

Call days upgrade

Manager

Let's go ahead and save

In

Oursainsburys.co up to your room

Directory

And then in manager were going to save it alongside those

Ok

Add a script

Default setting

Should be just fine so we're gonna touch that

And in this upgrade managers

Let's go ahead and create an

Sport

And what we're going to do is really cold as far

What's upgrade pool

And then a colon were going to type it as an array of

Ability opera

So this is going to be

Our customer resource here we can export that as an array

In inspector

If you look at the inspector we now have an upgrade pool

Where we can edit this size

And elements so if I go ahead and increase the size or a

I can't click add element by 1

Or I can increase the size with this

Size

Spinner here

We want one element to exist

Then I can drag over our sword rate into

And so typing it as an ability up

Are allowed us to

Only drag over

Anything that

Has a class name of a billion inherit from a billion

Now

You note that if this is not working If You Can

Strike the sword rate over into here

You may need to restart your goodle editor this is a known issue at least in the version that I'm using

Which is rc1

You're probably on

4.0 stable

But again if that's not working just going to restart your editor and it should work

Ok so that's our upgrade Paul and we've got

Sore

Rate good girl

Serena go back to our main scene in switch on over bed

The 2DS

So we've got the experience manager lit open up the Script

So this experience manager

Responsible for

Incrementing the experience

And telling us States

Update

So I'm going to want to have a level up signal as well

So let's

What's this

Experience manager script

Never get another

Cigna

Leveller

Sandwiches

New underscore level

Chadderton

So we're going to pass in the new level

Two player just reached in the level up signal

And we're gonna make that here so again

Experienced updated first underneath this

Black in ink

Experience

Emma is going to go ahead and level up

And what are we going to

We are going to Amy

What's the current underscore

Level

So let's go ahead in our main let's instantiate a child scene

Instantiate upgrade manager

Garden products somewhere near the top with the other

Energies opera manager we probably want to connect to this level up so that we can actually a sign

An upgrade

The player

So what I'm gonna do is I'm going to click into the upgrade manager

And I'm going to export

A variable

I'm going to call it Xperia

Manager

Export that as no

And then we're going to override the ready method

Funk underscore

We're gonna say experience manager

Dad

Level up

So level underscore up.com

On level

What's define the on level up function

And remember working

Taking a level the current level as an Int

So on level up beginning with k

Rational problem that can be used

Just

But what are we going to do on level 12

Going to ideally show you I'm

But first let's just a sign

That

First upgrade that we have

To the player so we're going to actually create a new variable in here

Current

Underscore upgrade

Is equal to in regular use curly braces

Because we are defining a new dictionary

Now

If you're taking this course you're probably familiar with programming generally

But if you're not familiar with

Dictionary

Dictionaries are basically a way of assigning data to an AI

So if I were to go into my current upgrades here

And say 10

Hello

What will happen if I could reference

This value hello bye

Using the key

So in other words I can do something like print

Different upgrades and

Brackets

Test

And that would resolve to hello

This is just a nice way of

Storing data that easy to look

So we're going to just leave this empty this current upgrades

For now

Then I level up what are we going to do

Well here's what we're going to do to manager ok

Subtitled by online-courses.club We compress knowledge for you!

Replace Google restore all of the upgrades we have

In

A dictionary object

And we're going to key it bye

The ID

That we use

Here in our swords

So we're going to have sword right as our key

And then we're going to store the actual resource

In an hour

And actually we meet use a nested dictionary

Which will be really cool

Ok so what are we going to

So unravel

We're going to first

Pick a random upgrade from the upgrade pool and it's very easy so we're going to save our chosen underscore

Is equal to

Upgrade pool

Picrew

This is going to do is this is going to pick a random element out of that array

And it's going to be possible for pick a random to return now so would you say

Chosen upgrade is equal to now

You can say what how is that possible

Well

If we start removing element from the array in the future like let's say that we have unique

Upgrades that can only be chosen one

That could potentially end up you know if we exhaust all of the passport upgrade then we say there are no more upgrades

Then

You could potentially be trying to pick an element from an empty array

So it doesn't hurt to be defensive especially when it's really easy to do something like this

So the next thing that we want to do is we want to see

Does this current upgrade

Have a key that matches Archie

Upgrade

So what we're going to do is really save our has

Upgrade is equal to

Upgrades

Has

And in our has we're going to pass in

Chosen upgrade at

I D

Now we want to get typing as what we can do as we can say as ability upgrade right here

And now we should

H

Suggestions for ID

If not

Has upgrade

Then what we want to do well we want to say current upgrade

Anarchy it bye

Chosen upgrade

I D

Is equal to

We're going to create a nested dictionary in here

I'm not going the same

Is we are just going to

Store a reference to The Resource so resource

Is chosen

So this is our actual ability resource file

And this needs to be in

Quotes just likes

Serena pass in our children upgrade

At The Resource key

And then we're going to do in Cork

Quantity

And then we're just going to send it to

Ok so

This is basically saying

Create a new object at the key which in this case will be sorted underscore

And that object is going to have a reference to the ability upgrade resource

That we

Shows

And then it's going to set up

U2 One

Now watch what happened

If we say else

So if we already have this key in the dictionary what are we going to do

Bring us a current upgrades

Androgen index it by

Chosen upgrade

And I'm going to do another index here

Which is going to be

Quality

Classical

Oh sorry this is should be quiet

Quantity

So you're saying ok well

If we already have the upgrade we have at least one

That means that we can just increment the quantity

Bye

1

Ok just for debug purposes we going to write another line at the bottom

Print

And then we're going to print a current upgrades

This is going to allow us to see

Our upgrades are actually working when the player levels up

So

This is not going to be the final stage we are going to introduce a UI with the player can choose an upgrade

But just to make sure that the upgrade is actually

The data flows actually work

We're just doing it directly for now

Let's Run the game

Because I forgot to assign my experience manner

So let's go ahead and go to my upgrade manager in my sim three

And leads

Drag the experience manager

Into that experience manager now that the

Ok so let's try this is

As I'm going to go ahead and collect

All these vile

Ok

So I just collected my face veil and levelled up let's go ahead and go over

2 hour hour

And you can see down here

Lad

Here's my object

So I've got my sword rate which is the ID of a resource

It is referencing a resource in memory

And has a quantity of 1

And you can see that while I've got the game on the other screen

That I just levelled up again and now the quantity is 2

So this is how I gonna keep track of all of our upgrades there each upgrade is going to have its own key

In this dictionary

And then we'll be able to keep track of how many times upgrade has been collect

And then what we're going to do is we're going to have to handle these upgrades in each individual ability

So that's the initial

That's required

Ability upgrades working I'm going to remove this prints

For now

Because we no longer need it

And in the

Next lesson

We are going

Go over

How do you actually choose this upgrade with a u
