All language subtitles for 35. Prevent Abilities from Being Chosen Twice

One problem that we still have that you may have noticed as that you can pick the accessibility multiple times now

If you are building a game you may decide that is fine that you want to play to be able to stack abilities but for

Purpose of this course we don't want that

To happen

And so we're going to prevent that from happening

And what we're going to do essentially

Filter out

Upgrades that exist inside the upgrade pool

In the upgrade

So let's go ahead and click into the Opera managers script writer

And

What we need to do is essentially modify the upgrade pool to pick up

Archie

What we're gonna need to do as we're gonna need to specify a Mac

Quantity for

Turn up

So let's before we do anything

I'm here go to our resources directory and then to

Let's double click on ability upgrades

Dodgy

Add LEDs

Do a Max quantity above

The name

So we're going to do at Expo

Bar

Max underscore

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

Quantity

And that's going to be of time

And we will set

2

Willie Venezia

And what I mean is that there's an you can have an indefinite number of these up

Ok so we have an X quantum you probably know this double click on her x

And the max quantity is not

Showing up and I have a feeling that this might be a good deal issue

So what we're going to do is before we do anything

Let's click this to a button right here

This

One that says managed object properties when you have over it

Go ahead and just

Harvey Proctor

Ok and then let's remove the Script by clicking this

Button at the bottom this reset but

That's going to get rid of all the properties

What's drag the ability dodgy back on to it

And now we have matched

That's probably a good elbow

But no worries we can go back to the store button here

Pace properties

And everything should be more

Restore

And now we've got the max quantity

This may not be a problem in the version of Google for that you're using

I'm on release candidate to so it may still be a remaining bug

In any case

Where is the fix for if you end up with a problem

And we're going to set our Max

Be here to 14 the

Which is basically saying we can only have one accessibility at a time

And the sword rate is also problematic because if we let it go indefinite

Then it could have a greater than 100% reduction

In it's cool down time

Which doesn't make any

So we're going to limit these sword great let's say we can limited to

What's the safe

Sorry to say you can do up to 50%

Sore

Tagra

So we've got there quantity defined in both are

Axe and sword resource

Let's go ahead and open up the upgrade manager script

And now we need to filter out the up

Import and this is luckily going to be

Pretty

So here we have the supply upgrade

Function and this is where we going to be doing our pool

So

We have our upgrade

And what would I do is really say a new plot

And we'll say if

Max quantity is greater than 0

Then we want to do so

Filtering

So let's grab the current quantity

By doing vodka

Quantity

Is equal to

I just copy this line on

22

Credit upgrades upgrade.ie

Going to say that

So that's going to give us the current quarter the after

Stop lying

And then what will say is what I say

Current

Equal to

So if current quantity is equal to

Upgrade dart Max quality so this is the point at which

We are going to want

Remove this upgrade as an option from the

Upgrade pool

So the weather

Do that is we will filter it just like we filtered

Down here in our pick upgrades funk

So we can do basically the same thing so I'm going to say upgrade

Equal

Upgrade

War dart

Filter

Supply and inline function again

Funk

Let's say

Google underscore upgrade

As the argument is coming

Inline function

So that's our one of our pool upgrades again

The filter function

Works by applying the inner function for every single lol

In the array

And if there's a function Returns true then

Never Returns false

Women's heels

And so

We're going to be calling after

Funk poor upgrade

And what week

Return true

If the ID is not

The current

Right so I'm going to say return

Upgrade

I D

Is not equal to

The upgrades coming into the supply upgrade function

Ok that updates our upgrade pool cause again the filter function Returns a new array Swift

Override the upgrade

And I believe that should be it so let's go ahead and

Play a game

And what we're going to do is we're going to see if we can

Take the ass

So I do the first up

Ok I'm going to pick the

And then

Going to level up one more time

Where's my new accessibility

And see

So I ended up with a problem

And the problem is that

We're gonna crash and the reason is so

So think about

The crash little bit a good actress

So

Sing For A Moment to yourself

Why do you think work experience in a car

What's review the code

So what is the code DO

Well we're filtering out some upgrades right but then we're also running pic

Upgrades

So think about yourself a little

Here's Leanne

Pick upgrades

Always

ASDA cheese

2

Because we've hardcore

To hear

The problem is once we filtered out the axe in since we only have 2 upgrades total

13th zodiac

There's only one upgrade left to choose from

Now that would be fine x x

Remember where filtering the upgrades as we pick them in the pick-up grades and May

And so we're actually ending up with an empty array after it picks the first sort of

Why

Because it's picking a random element from the filter upgrade

Adding that as an option

2 hour

You ice cream by adding it to this

And then is re-assigning the still upgrade by removing

That option

From

The

And sold by the time we hit the second iteration

This pic random is returning now

Because there are no Ella

Unfortunately the fix for this is going to be rather simple

We just simply have to check

Chosen upgrade

Is equal to null

We're going to

Warwick

And so what brake does is it ends the function or the for loop execution so this could be

10000

Chooses on Noel option on iteration 2

It won't not do the rest of the 9th I

And choose an upgrade

I will only be now if they started up

Here's my

So if they're

At least one element it will never be no

But

It can be

So that should be the fix

Let's Run the game again in make sure that

Is working

As we want

Ok I'm going to pick my ass

And then

So now that I've levelled up again

You can see the

My only option is to increase the sword

Now

There is a problem here

And we will probably address it later

If you

Keep playing a game until

Required

Sword upgrades

Then what will happen

Is

The game of soft lock because there will be no options presented

To the UI element that is pausing the sky

We will address that later

But for now we've got a couple of errors being printed in a console

And

These errors are telling us that we can't

Values from an empty array

So if we double click on this error in the console

You're take us to the upgrade manager

It looks like we just need one more

Check

Or I guess we should probably change this checks

This chat technically works but

It's printing errors to the console which means it doesn't like the way they do

So instead of doing that what we're going to do instead as we're going to

Write a different estate

If filter upgrades

Dart

Size is

Equal to 0 then we're going

And we can remove

Directions stop printing

Clothes airer

Ok thanks I just got my second

Upgrade here in a minute longer seeing any errors

Next to the console

And that should be good now one final thing that I want to do

Before ending this lesson is the axis or little bit too frequent so I'm going to control shift

I'm going to open up my accessibility controller

Right here

And I'm going to click

Timer

I'm just going to up the wait time for something

Next 3.5 which I think is a little bit

Reason

And then I'm going to go ahead and run it

And let's see

How that feels one side

That feels a little bit less soapy to me

Engine has plenty of room

To improve the access efficacy

With upgrades
