Unity Artificial Intelligence Programming - Fourth Edition

Touch

Another sense we're going to implement is Touch.cs, which is triggered when the player entity is within a specific range of the AI entity. Our AI character has a box collider component, and its Is Trigger flag is on.

The code in the Touch.cs file is as follows:

using UnityEngine; 
 
public class Touch : Sense { 
  void OnTriggerEnter(Collider other) { 
    Aspect aspect = other.GetComponent<Aspect>(); 
    if (aspect != null) { 
      //Check the aspect 
      if (aspect.aspectName == aspectName) { 
        print("Enemy Touch Detected"); 
      } 
    } 
  } 
} 

We need to implement the OnTriggerEnter event that is fired whenever the collider component collides with another collider component. Since our tank entity also has a collider and rigid body components, a collision event occurs ...
