14.3.4.1 Script Breakdown
The enemy behavior is based on path following provided by the BaseAIController.cs script.
It derives from the BaseArmedEnemy class, discussed in Chapter 9:
public class Enemy_IP : BaseArmedEnemy
{
The BaseArmedEnemy class adds a data manager and support for the weapon system
to our enemy script, but it does not deal with anything more than that. This script starts
out by adding collision checking and will deduct health from the data manager when hit:
public void OnCollisionEnter(Collision collider)
{
In this game, the player projectiles are set to use layer 9 (named player_projectile). When a
collision occurs with this enemy, the colliding collider is passed in as a parameter and its layer
compared. If it matches with the player projectile and this enemy is not respawning, a call to
the data manager stored in myDataManager is made to reduce health by 1:
if( collider.gameObject.layer==9 && !isRespawning )
{
myDataManager.ReduceHealth(1);
