Before we wrap up the course there is one final bug to address and that is that

Enemies can get stuck in the wall

As you say

Right here

And this happens under a verb

Specific Circumstance which I will describe

Now

So let's go to our handy paint and let's

Draw a line that rep

Against the wall and if you recall

The way that we

Spon End

Is that we take the player position which is let's a right

Who's the player

And we basically shark

A vector

Along some Direction

To see if there is a collision

Edit there isn't a collision

Respond

Enemy

What happens if h

Raycast

Ends one pixel before the wall likes

And doesn't register a collision we say oh

Well then that means that there is no collision in so what we're going to do

An enemy

So we spawn the end

Play here

However

The enemy is now on top of the wall and

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

Remember the enemy has a collision shape which is like a circle

Are the enemy ends up with a circle Collider

That is halfway inside of a wall

So the fix for this is really simple instead of checking the exact distance along which we

How to spawn the end

We're actually going to add

An additional 20 years so pixel check

Like so

So that means that if it's whole range if this whole

Line

Does not contain a collision

Then we'll go ahead and spawn the enemy

The tip

The Orange

Desired

Sponge

So essentially just adding an extra 20 years ago pics

Checking to the

The array

So that we can be guaranteed that there will be at least 20 pixels of distance between

Responding the enemy

Between the

So let's go ahead and open up our enemy manager

And implement exactly that fix so go ahead and open up the screw

And basically and hear what we've got going on is we are setting the enemy spawn position

To the player global position plus that random Direction

Choosing

Up here

X the spawn radius

And like I showed in the drawing we basically want to

Something

20 additional pixels

To the Ray

Checking

And so what we're going to do for that

Is were going to create a new variable called additional

And we're just going to random Direction

Times 2

And then in this line we were constructing the physics re query parameter

We just simply going to add that additional check offset to the second

So it's going to be spawn position Plus

Additional

Check

Off

So what does essentially going to do is that's going to create a rave and the player position

To the spawn position that we want to have for the enemy

But Plus

An additional 20 pixel

In the same direction

And as long as that raycast does not return a collision result

Then we can spawn em

So you can run the game to test it's going to be very difficult to test

But

If you play the game a little bit more you should notice that it stops

Happening

And enemies are still spawning like normal
