How to make something happen when all of one type of enemies are destroyed by bullets.
I want to have green enemy set a sprite of a key active when all green enemies are dead while having red ones destroyed to do something else. Would I tag all green ones and say something like Update { If (gameobject.tag(“greenenemies” == null ) { Key.setactive;
} And where would I put this code on an empty game object or my character or my key. Thanks in advance.
Based on what you mentioned in your question, a simple way to do this would be to check your scene for enemies with certain tags when an enemy is killed; there isn't a need to check every object in the scene each frame with Update(). Something like this:
//when an enemy's health is <= 0
if (GameObject.FindGameObjectsWithTag("green").Length == 0)
{
//do something
}
else if (GameObject.FindGameObjectsWithTag("red").Length == 0)
{
//do something else
}
There are obviously things you could do to optimize this code, but this is simple and should get you the results you want.
Okay thank you would I put this in the start section of my code I’m a bit confused as I’m new to game design. :)

So no, not in start (unless it's the start of something that happens when an enemy is killed)
You didn't post any code, so I don't know how you're actually removing health from your enemies. However, you just need to put this check wherever you're doing something like enemyHealth -= 10.
You could have an enemy spawner increment a counter if you have a variable amount of enemies or enemies that are constantly spawning in. If the number stays the same, you could either search for the enemies, drag and drop them into a list and use the list count, or just input the number.
Then on the enemy you could decrement that number in the OnDestroy() method or if you have a list you don't have to do that. Just put in the OnDestroy method a check to see if the number / list count is <= 0.
If it is, you do whatever you want to do when they're all dead.
