Hello
I want to set up aroud 20 spawn points on a map. I want them to spawn randomly on these spawnpoints, then disapear again after half a minute.
Is this possible? And if, how do i do this…
Please note that I’m pretty new to programing so please include scripts 
Nobody is going to write scripts for you. Go to www.unity3dstudent.com and teach yourself.
You can do something like the following…
1.) Create a spawnpoint prefab, that basically contains an empty gameobject, tag it as ‘SpawnPoint’.
2.) Create a SpawnManager script for your game, that when it starts, randomly places the
spawnpoints around your map, using Random.Range()
3.) In your GameManager script, get a list of all your spawn points using GameObject.FindGameObjectsWithTag(“SpawnPoint”)
4.) With that list of spawn points, simply pick a random one, then use GameObject.Instantiate to instantiate your enemy prefab on the random spawn point position.
