The Ultimate Battle of Ultimate Destiny - Unity 2D Game Development - page 95

The boss should only be able to kill the player and enemies by squishing them
when he falls. To support this, create a new empty GameObject, call it Boss Crush
Zone , and make it a child of the Boss object. Give it a Box Collider 2D component,
and make it such that its size covers the bottom portion of the boss by setting its
Transform position as X: 0 , Y: -0.175 , the Size fields to X: 3.74 , Y: 0.2 , and
set the Center to X: 0 , Y: 0.09 . It should now be aligned at the bottom-center, as
shown in the following image:
Create a new script called BossCrushTrigger , attach it to the Boss Crush Zone
object, and code it up as shown in the following code:
using UnityEngine;
using System.Collections;
public class BossCrushTrigger : MonoBehaviour
{
public BossEventController bossController;
void OnTriggerEnter2D( Collider2D collidedObject )
{
if(bossController.currentEvent !=
BossEventController.bossEvents.fallingToNode)
return;
if(collidedObject.tag == "Player")
collidedObject.SendMessage("hitByCrusher");
}
}
