So what makes a game a game is well preventing the player

I'm doing something and then having them actually able to accomplish something

Because they completed that challenge I mean that's pretty obvious right so let's Create something called

Date

He wasn't actually going to move this down and

Recreate some or Land Rover here

How much is grab one of these grounds and paste it

2

That right here and drink a little bit this going to be a gate

And then we'll take this

Delicious cafe in

Again can bring it up here so there's a gate to enter a new Zone and let's just put

Here as well

Beautiful writing

This gate can only be

Cast if you have a key

Ok

So we're going to do as we're going to first and foremost

Let's make this gate

I'm out just wait for now

And that sort of

Links

The store to the key here

Ok

So we need to be able to check to see if the player has an inventory item

If they do

Then the gate what automatically open right

So let's make sure that this ground that we copied and changed a little bit

What causes gait

And it's put it in our prefabs

It'll be an original prefab

Perfect by the way guys if you're getting errors while you're working on this

Will eventually need a cleaning job but they're actually not causing any problems so

Clear this out for now

Skate here

Create a new script

That will do something if the player has

Inhibitory item so it creates a new c-sharp script

Weird colours

Gate

Again if you get weird there's like this it's just part of the course with unity

I'm not cleaning up eventually but I don't worry about him right now

A m dragon will be here

And working at

Agate script

A select in the gate to dragon Andover

Now currently do anything because we open up the Script

It's nothing so what we're going to do

Is there actually going to create a new on trigger enter

Auction

Remember that one that we had for a collectible here

On trigger enter 2D

What is going to use this same sort a function for the gate

So ontriggerenter2d

Do something

What's out of bracket down here

If you're going to use this ontriggerenter2d

We actually need a box Collider

On this gate that is a trigger ok

Not only do we have this polygon Collider that actually stops the player

It's not a Trigger

We also want a trigger on here as well so we can literally just add another Collider a box Collider 2D

And this one

Is going to be a Trigger

The size

A little bit bigger

Say something like this

Alright

Does go back into a script

Create an if statement

If

The collision

There you go here which is a collider2d variable type

If collision

Die gameobject die name = player

Debug.log

I'm triggered by the player

I say that out and

Can't we just testing to see if it works

Again the player is going to

Stop

Moving because there is actually a polygon Collider here that could have stopped the player

There's also a trigger here this box Collider Trigger

Set to true

That's going to be

Used by the gates script to check and see if the players trigger in within this zone

So if it doesn't make sense that s*** play here and hopefully

Make a little bit more sense to you

Alright time exploring

I'll be fighting enemies listening to call music

Right now it's pretty so it's getting on and there we go I'm triggered by the

Perfect

Then we can do it again and again so there's no one there

You should go to to

Play music

This message has happened to three times now

Perfect silver trail player

That's great

So now we need to do one more thing we need to check and see

Is the player

Has the key

So what we're going to do some pseudocode here

If the player inventory

Has he won

Then

Destroy Me

How do we check if the player has key won

Let's go back to the new players script

And take a look at our inventory item scripts

Leave her now dictionaries contain a functionality called contains key

So we could actually write something like

Inventory contains key

NN whatever that key is

That's the

We were going to write this ok

Remember we need a reference to the new player

So

The way that we would write this out is if

Game object that finds interest because will clean it up in a bit

For now just bear with me if gameobject that find player

Getcomponent

New player

Even Tory died

Contains key

Key1 and it's not saying contains an actual like key that you unlock a door

What does the saying is it contains a dictionary key

Meaning of the word Tiguan boot or gloves or sore

Or trophy or gem key

Just going to look for all of the various keys

Or entries in the dictionary item

If I find it

Then

All it's going to do

Is destroy

This game object in what is this game object

Is this gate

So that should do it

Let's see if it actually works ok

Does double check here

If we actually zoom out

And select the key here

Noticed how the inventory string name is not he won

She always want to double check and make sure everything's matched up remember we created the little smile inventory the real change

Key wine in the morning to change the inventory Sprite to inventory key

Say that

Swords testicel first let's go over to the door and see if it actually opens

When we don't have the key

Good

Just triggering it

That's expected

Programme de quillan

See what happens

Alright I've got the key

It's showing up in my inventory that's good

What's the other day actually open the gate

Did awesome so we are good to go to the next level alright at least that's how old function

In our prototype we will be able to go to the next level after we got the key

Remember guys when you're creating scripts

You want them to be as broad engineering as possible

So far our Gate Script if we open that up

A very specific here

Is looking for key wine

Well what if we want to have multiple Gates with multiple keys

Are we going to do is

Create new variable appear serializefield

It's going to be a private

String

Anything to be called required inventory

About required inventory item string just so extra clear on what this variable requires

Ok we can just copy that

Just paste it right here

And it's going to look for whatever we specify right by The Fall it's going to be

Display

So we need to go into unity

In Spotify

Inside of this gay

What word requiring well requiring key one

Say that out

And

Alright looks like it works

This allows us to create multiple Gates

So if I take this gate here

Remember if I make changes to a prefab in the actual seen here

I need to make sure that I save these changes to the prefab

I added this case grape that out of the box Collider

Remember if we have a prefab that we make changes to in the actual sea view that are going to be applied

Prefab itself the root prefab so say drag this gate here may be right there

No it's only got a polygon Collider on it and it doesn't actually have the gates Krypton

We need to make sure that we go to the gate that we were just heading

And go here and this is going to allow us to apply all of these changes

To that route prefab

Here we go it's a now we can put a gear or here

And

We could have a require something else right would you have a require and I know a pumpkin and weak

Maybe two of them right to these pumpkin Gates

Requires you to have a pumpkin and then we could maybe

Put something special on here right I maybe you could put in here another key

And this would be you know

The master key writing

And then you can change it to be

Gold

Sonos help just by adding a simple Gate script with some inventory functionality

We seriously created in entire game loop it's really amazing housesimple creating a core game repairs

Ok so we have this gate here no that's how it's got some weird layering issues

Well we could have drag it blow

Round one

There we go Sonu layering issues there

One more thing we need to do for this gate before the

Script is complete

We seem to make sure we remove it from the inventory

Meaning remove the key from the inventory

So I'm going to do is

Gameobject find getcomponent new player copy this reference here and we'll talk about how I can clean this up

In the Future episode

Remember that function we wrote remove inventory item there we go

Emirates going to remove it

Required inventory item string

And if you go back to a new player here if you recall when we remove that inventory item

It's going to remove it from our inventory dictionary

And then it's also

Going to set it back to blink

Test out

See how it works

Rocky

And

We remove the key from the inventory and destroy the door
