Time for action – Calling custom functions

We have our SpawnEnemy function, and now we have an array of AwesomeEnemySpawner actors in our AwesomeGame class. Let's call SpawnEnemy.

1. Let's add a new function to AwesomeGame called ActivateSpawners :

   function ActivateSpawners()
   {
       local int i;
   
       for(i=0; i<EnemySpawners.length; i++)
           EnemySpawners[i].SpawnEnemy();
   }

2. This will iterate through the EnemySpawners array and call SpawnEnemy on each of them.

3. Let's call our ActivateSpawners function from PostBeginPlay:

   simulated function PostBeginPlay()
   {
       local AwesomeEnemySpawner ES;
   
       super.PostBeginPlay();
   
       foreach DynamicActors(class'AwesomeEnemySpawner', ES)
           EnemySpawners[EnemySpawners.length] = ES;
   
       ActivateSpawners();
   }

   Now, PostBeginPlay is getting an array of all of the spawners, and then calling the function that activates them.

4. Compile the code and test. Now the log in AwesomeEnemySpawner's PostBeginPlay should show up:

   [0004.73] ScriptLog: SpawnEnemy called...
