How to Spawn Enemies (Unity Tutorial | 2D Top Down Shooter)

In this Unity tutorial we're going to look at how to create enemy spawn points.

These spawn points will periodically create new enemies, giving us an unlimited horde of zombies to fight.

This is the twelfth video in our series showing how to make a full top down 2D shooter game in Unity.

I usually struggle with unity programming tutorials but this has been amazing! thank you :)

[billietheweirdkid]

Incredibly clear!! My script didn't allow me to add values in the inspector but I corrected it with chat gpt and it worked. I love that every move is backed up with an explanation, as a student I need to understand why I'm doing it.

This is extremely simple to follow and understand! I didn't know it was possible to do this without Coroutine, so this made life easier lol

[stevethepirate]

very clean and consise! thanks for the help!

[kelnnermagno]

Great video, and great explanation, thank you so much

so i have a spawner with a graphic and want to make it destructable treating it like an enemy

[tonji_]

I dont know why but my Enemys are not spawning? It doesnt create the clones or anything, maybe it correlides with another script but to figure that out... ouf idk

[jacobzak]

Thank you! Didn't know it's possible without using Coroutine

Hey for some reason when I add in the spawner it spawns a few in and then the error: ''MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object. I assign the enemy prefab to the script but then I get that error after the enemy spawns in a few times

I am making a 2D Rocket Shooting Game for my class project, and I have EnemySpawner that will increase the spawn every once in a while, but what I don't know how to do is to make more variants of enemy to spawn. Also I kinda want stages so like the higher stage will have more enemies and variants and then a certain stage will have miniboss and main boss.

Hello, i followed the tutorial, and i have an issue where the enemy only appear in the Scene Screen and not the Game screen, why is that?

TLDR:
The enemy spawned but they are invisible in game screen, but all of their logic is there

When will you upload more parts of this series? 😢

Hi! I have a question, If I use a prefab from a folder outside of the scene, it does not know where the player is because the player is in the scene and in the prefab I cannot use things from the scene to be set as the player, and if I use a enemy that is in the scene, when I kill the original enemy, no more can be instantiated, what should I do?

[tPlayerioT]

instead of Void in method setTimeUntilSpawn()

i would do a return;
float SetTimeToSpawn()
{ }

on which:
if(isRandomRangeEnabled)
{
((random range here))
isRandomRangeEnabled = false
}
timerUntilSpawn -= Time.deltaTime;

return TimerUntilSpawn;

and then put that method inside update and do if using the method because it returns the timer. The boolean would be in inspector so i could reenable it and have multiple random ranges.
if im not mistaken these should work fine

Helpful video! I'm going to try to make my player the enemy spawner where it always spawns right outside the camera's view

[oziic]

The enemys spawn but theyre like hidden in game view

[omar-]

thank you very much ! I tried by myself but could'nt make it work

[MawaJawa]

I have made it so that the spawning is working but when they spawn they only stand still and wont move, how do i fix this?
