Game Development How to Make a Video Game Pickups Spawn Pickups Randomly

SpawnArea or SpawnArena? My MonoDevelop doesn't have SpawnArea, but instead, it has SpawnArena.

So I tried to type

float positionX = Random.Range (-spawnArea, spawnArea) ; But when I debugged the script, it said that it doesn't exist. Please help!

Hey There,

I'm guessing you probably have a typo near the top of the FlySpawner.cs file where we declared the float variable.

You should have (near the top) around line 12 the line

private float spawnArea = 25f;

This is where you probably typed "arena" instead of "area".

Then your

float positionX = Random.Range(-spawnArea, spawnArea);
float positionZ = Random.Range(-spawnArea, spawnArea);

should be fine. I've done that a few times... mis-naming a variable and trying to figure why it isn't auto-completing!.

Keep Coding! :)

:dizzy:

Because that's what's needed for the code to execute properly.

We need a Random number generated in the range from the negative value of spawnArea to the positive value of spawnArea.

Once you take the course, you will see how / why these values are used.
