Another thing that we Don't Have Yet built-in our game is to increase the frequency of enemy spawn

As the game goes on

So in games like vampire survivors

The longer you play the game

The more enemy types you encounter and the top of those any

Get is a we need to be able to have a wake

To know

How far along the game is

And we're going to

Sorry off by handling

From the arena time Manor

Anaplan is basically going to be every 5 seconds or so

We're going to emit a signal from the arena time manager

That basically says hey

The wave

Progress or the arena progress

Has gone

And then there are various systems in the game that can listen for that

And make adjustments as

So let's start off with that and then we'll work on

A little bit more so

Every 5 seconds we want to increase some difficulty and I think what I'll do is I'll just call it differ

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

Right so I'm gonna create a new variable

In my Arena time manager script here would you can open up from the main

We're going to call the

Bar Arena underscore

How much is call it 0

4

And what we're gonna do is we're going to override the process

I'm here

Process

Dealt

We're going to go out in path

Now why are we overriding process function basically every frame were going to read the current wait

Time for the current time left

And we're going to see if it's past a 5

And so what we're going to have to do in order to check that is we need to store the previous time from the

Frame

So we're going to say appear via previous time

Sequel to

0

And then in already method above this time

Not connect line

Let's see

The previous time

Equal to

Timer

So I just said it to

The wait time

Immediately

What's the final constant variable that can represent

How often we

Increase the difficulty

So let's create a can't stop here

I'm going to call it can't

Difficulty

Interval

And we'll send it to

Ok sauna prices metal let's do this for going to save our

Next

Time target

Is equal to

Timer

Start wait times are in 8

The tunnel

What time are we going to subtract

In parentheses

Arena difficulty

Plus 1

And then x

Difficulty in

And let's wrap this whole section in parentheses as well

And so what is this statement saying basically what we doing it's going to take the current Arena difficulty and ad12

And then multiply that by the difficulty in

And what is this going to tell as well

This is essentially going to say ok what is the time that needs to be remaining in order to

Increment

The arena

Difficulty

Insole

In here

For example we have 60 seconds set for the time away time

It's going to be 60

-

This will evaluate 25 when the game first start

Because the arena difficulty is 0

Adding one

And then x

And then when you're in difficulty goes up by 1

Little then by the time I wait time -10

You can see how

The target time

Goes down by

5 seconds every time the arena difficulty close

This is our next time

Now we actually me not need this

This time

Let's go ahead and

So

Our next time target so what we want to do is want to say

Timer time left

Is less than or equal to the next time

Then we can increase the arena difficult

And with my signal so up

The top

Above the const

Let's do signal

Arena

Difficulty

Increase

And I must go to bed in a minute that down here in this if block

Arena

Difficulty increase

So we actually do not need this previous time so

We went with a slightly different approach than what I originally thought

So we don't need to said that in the rain

Removed

So that should work let's go ahead and just print Arena difficulty in here

Endless Runner game in see if that's

Printed

Simon a move my game to the other window to my other monitor

Just so I can watch that help but we've got one right there

I wish I could see it again

To write there

Set work

Correct

But of course we need to do something with this song and get rid of this print statement here cos that's unnecessary

And let's create a parameter for this Arena difficult

Increase request so we're going to

Put parentheses at the signal definition

Here

And we're going to say Arena

Underscore

Call Ty

And this is going to be in

And then Indian MIT down here

We need to make sure that we passed the arena

Ok

Our first

Place that we're going a listen for this difficulty increase is going to be in our enemy

Manage

Let's go ahead and open up the enemy manager scene

Another export variable

Bar

Arena

Time

Manager

And this is going to be of type node

Number for refund

Let's go to our

My manager over here

And drag

In the arena time manager you can also just click assign right here

And then click the Aria time and

So now that we've got that

Set up in our

Weak ankle

To that singer

So in the ready method below the timer line

Arena time manager

Arena

Difficulty

Interest

And then let's create a very long function name here

On

Arena

Difficulty

In

Ok and then let's Create that function

Ok great so we have the honour Arena difficulty increase

Function

Here

And let's write pass so we can think a little bit about what we were

To do so in our my manager if I go out in open

This scene

If I look at the timer we have a wave time of 1

One thing we could do is we could reduce this wait time

As the difficulty increase

I was thinking about that so let's say every minute we want to wait

Going to go down

1 seconds

So

We want to set our wait time

To decrease

Bye

.1 / 2

So basically there's

12

5 Second segments within a min

And we want

The timer to decrease by .1 seconds after

So let's go out here in

Get that

Going

So the way we're going to handle this is actually going to turn on one shot in the time

And then we have this on time or time out

And what would you do in the on timer timeout is

We just going to restart

The timer

Here

On the 1st

So let's do

Timer

In why are we doing this instead

Just having it go over and over and over again

What is allows us to do is this allows us to change the wait time in this function here

And then to have that wait time update

On the next time out singer

Right

So if we updated the wait time and then restart the timer here

We may actually end up with a longer gap between enemies and we're expecting

So what's the timer has half as left

And we re calculate the weight

And then we restart the timer

Well that means

The timer is going to become greater than half as in start counting down to that actually creates a little bit of a gap

Instead of being continued

And so what we're going to do here instead as we're going to say

Set the wait time in this on difficulty

Increase

Mr function

But don't apply that until the next timer don't start call here

On timer time

So our wait time what is our desired weight time

And don't forget we have the arena difficulty coming in as an

Let's do a Rena difficulty

End

So let's call this variable via time off is equal to

.1 / 12

Right because we're doing 5 seconds per

Difficulty increase and there will be

12

Five second segments in a minute

Right so it'll be .1 / 12 in parentheses

I never going to multiply it by

The arena difficult

Right so as soon as it's Arena difficulty it's 12

Which is a min

Then this is going to be .1

When is hits 2014

To let us go ahead in French

The time off

That were calculating just to make sure that

Calculating correctly

And a letter reference are timer

And set the wait time

2

Now we need to store the base weight

I'm here so let's come in this out if you hit ctrl k

That will comment alone

For you so that it doesn't run

And then let's go ahead and you're a couple of things so

Blower export list you on ready

Via timer is equal to 9 time

And let's highlight this dollar sign timer in a red

Hit ctrl d

3 times

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

To highlight all instances except for this one online 8

Orange going to write time

Let's create a variable underneath that already called variable

Spawn time

Is equal to 0

In the ready method above the Kinect Lines

What's 2 base

Spawn time

Is equal to

Timer that wait

So why am I selling at here instead of hardcoding at this means that

Let's say that we want to increase our wait time from Game balance reasons the initial wait time 21.5

Debbie spawn time will automatically be updated so we're not relying on a hard-coded number for the calculation

And so now down here in the honour Arena difficulty increase

I can't control K2 uncommon deadline

Timer wait time is equal to base

Wait

Bass spawn time Reddit

Miners the time

Right

And we probably want to clamp the time off

To a certain number

So let's just go ahead and do that

We're gonna say time off

Just below the assignment of the time off variable

Let's say time off is equal to the max

Time off Leisure Centre .5

Is the quickest at the timer

Maybe even list

Basically we don't want to do because I'm super overwhelming word spawning so many enemies at a time

Workable

So time off every falls below .3

It will be

Climbed

So I got this print statement

Let's go and see if that's working so it's runny

And I'm going to shrink the size of this window

We can see

So I time off is not

Alright ok

So I did this wrong so this time off is actually going to be a very small value at first

So we actually want to use

Where should I want to sort of the inverter so we went to use amen

We want to say

The minimum of

Time off in points

So what is the saying is ok

Is the time off exceeds 7

So that is sort of an inverse of what we just did

Which means that the weight time can only ever be

A minimum of

Let's go ahead and run

LFC

What are up cancel out

You could see that the first number for to this point 008

3 repeating

Then the next number is point 016

Repeating

And then 0 to 5

So enemies gonna start gradually coming

Quicker and quicker as the game goes on but it's very glad you're right we're not even up to attend to the second off

So this is just kinda like the gradual difficulty increase that we can use

Is granular enough that we can

Gradually increased the

Difficulty of the game

Not super frequency we don't have to worry about life

Constant frame based calculations as to the

Appoint 1 seconds off

You can see that you should already noticed that there are 4 more enemies coming out

And I want because I got to 60

No the last thing I want to do is it since we have been adequately tested the win condition

Let's go to our Arena time managers are go ahead and open up the arena time

Go to the timer

And let's set the wait time to listen to 5 minutes which is 300

So that should give us a little longer experience that we can use when where

Developing a game for

Now or setup to use that

Difficulty increment

In other areas of the game
