In this tutorial I explain how to write a C# script that will allow you to spawn obstacles onto your scene using prefabs and instantiate.
============
In this video I will show you:

Sick tutorial, dude! I had this exact same question, except I'm new to Unity so I had no idea on what to do. This still holds up even 7 years later.

9:35 OK FINALLY I was so confused because nowhere could I find where you actually reference the prefab itself god bless you

At 9:01 you said we could use a boolean that changes to true when the game is ready to start. How do I know when the game is ready to start? Because my game has a title and doesn't start right away, so i dont want the enemies to spawn before the game actually begins, but how can I do this?

hello from french,
thank you for tuto, you help me ^^
a good day.

[boniebob]

When the camera projection is "perspective" the objects despawn normally, but when I set it to "orthographic" the objects spawn faster than they can despawn. Can anyone help, plaease?

Hi, I appreciate the video. Just a quick question : so I'm working on a simple 2D side scrolling runner, the idea is to deliver Pizza to randomly generated houses : green red and blue ( to add a bit of challenge ), will the script you provided in this video work ? I've been trying for so long but I can't make the houses spawn after the player collides with them.
Any help would be appreciated. Thanks.

How can I make more obstacles spawn through the progress of the game? Also great tutorial.

I have a small question, I'm shooting bullets, although it seems I'm creating multiple bullet game objects and I only want to fire one of them when the space key is pressed, how do we limit the rate of a prefab?

[milo]

I was wondering how you would make the Asteroids spawn downwards vertically, instead of horizontally. Thanks.
