Collision detection not working as intended
Hey all, newbie here I am trying to make a basic 2D platformer and getting help from a book named "Unity 2D game development" So I have a bullet prefab with box2D, and a collider for my enemy object. Using events and delegates for hit detection script(Know it's an overkill, just book stated so) Problem is, when I am shooting an enemy, it doesn't always kill him despite the simple Destroy(gameObject, 0.1f) command. Sometimes it hits and kills, but sometimes it doesn't(Bullet gets lost, so I guess collision is made) Any idea why?
using UnityEngine;
using System.Collections;
public class TakeDamageFromPlayerBullet : $$anonymous$$onoBehaviour
{
public delegate void hitByPlayerBullet();
public event hitByPlayerBullet hitByBullet;
void OnTriggerEnter2D( Collider2D collidedObject )
{
if(collidedObject.tag == "Player Bullet")
{
if(hitByBullet != null) hitByBullet();
}
}
}
public void hitByPlayerBullet()
{
GameObject deathFxParticle = (GameObject)Instantiate(deathFxParticlePrefab);
Vector3 enemyPos = transform.position;
Vector3 particlePos = new Vector3(enemyPos.x,enemyPos.y,enemyPos.z +1.0f);
deathFxParticle.transform.position = particlePos;
Destroy(gameObject,0.1f);
}
I think your bullet is too fast and small, so it isn't above the enemy collider.
Check if changing the collision detection to continuos works
Probably the bullet is getting destroyed before the collision registers with the enemy. This is a common problem when making collisions that destroy both participants. Instead of destroying them in the event, simply set a Boolean flag, and destroy them in Update.
Thanks! Changed bullet's code to Destroy(gameObject,0.1f); and it helped
