The next thing to do is to actually spawn enemies against the player. This can be done in many different ways. Here, we are going to see a simple way to do that.
The key concept is that we have a coroutine that gradually spawns enemies.
Tip
If you are not familiar with coroutines, you can check out the following documentation: http://docs.unity3d.com/Manual/Coroutines.html.
Let's get started with opening the EnemyScript and adding a new variable that holds the position where we want to spawn the enemies. Since we want to set this in the Inspector, we need to set it to public:
public Vector3 SpawnPoint;
Furthermore, we need one more variable, public again, that stores the prefab for the enemy in order to spawn all the enemies:
public GameObject enemyPrefab;
Also, we need some other variables that we are going to use to set how many enemies the coroutine is going to spawn and how fast:
public int numberOfEnemiesToSpawn = 50; public float minSpawnTime =...
