I want my bullet to get destroyed OnTrigger, however it doesn't get destroyed but that Debug.Log works fine. I have tried everything such as rewriting the script, replacing it and attaching it over and over again. Could somebody help me?
Here's my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enemy : MonoBehaviour
{
public GameObject Bullet;
void OnTriggerEnter2D(Collider2D collision)
{
if (collision.CompareTag("Bullet"))
{
Debug.Log("I die");
Destroy(gameObject);
}
}
}
You're destroying the Enemy gameObject. To also destroy the bullet, try the code below:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enemy : MonoBehaviour
{
public GameObject Bullet;
void OnTriggerEnter2D(Collider2D collision)
{
if (collision.CompareTag("Bullet"))
{
Debug.Log("I die");
Destroy(gameObject); // destroying self object (Enemy Object)
Destroy(collision.gameObject); // destroying collided object (Bullet Object)
}
}
}
If you want to destroy the bullet you should pass the bullet object as an argument to the function Destroy(), but you are passing the enemy object.
replace Destory(gameObject) with Destroy(Bullet).
Or if you want to destroy the bullet that get triggered replace it with : Destroy(collision.gameObject)

public class CountScoreAtWall : MonoBehaviour
{
//Varriables
public GameObject[] prefabs;
public Text animalPassedText;
public int animalPassed;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
animalPassedText.text = animalPassed.ToString();
}
void OnTriggerEnter(Collider collision)
{
if (collision.gameObject.tag == tag)
{
animalPassed = animalPassed + 1;
Debug.Log("Animal Passed showed");
}
}
I want to let my clone Prefabs from Instantiate() touch the wall and then the score will Increase by 1 to animalPassedText but I don't know how to do that.
So please help me. ToT
Possible solutions:
1- Either the wall or your prefab should have a rigidbody to make OnTriggerEnter work. So check if one of your game objects has a rigidbody and they both have colliders.
2- Maybe your "tag" variable is not matching with collision.gameObject.tag, so if block is not triggered. Print collision.gameObject.tag and tag to see if they are matching.

public class Pickup : MonoBehaviour
{
public GameObject _Pickaxe;
// Start is called before the first frame update
void Start()
{
_Pickaxe = GameObject.Find("Pickaxe");
}
// Update is called once per frame
void Update()
{
}
void DestroyGameObject()
{
Destroy(gameObject);
}
private void OnTriggerEnter(Collider collision)
{
Debug.Log("Collided with +" + collision.gameObject.name);
if(collision.gameObject.name == "Pickaxe" );
{
Debug.Log("Touched pick");
}
}
}
In my script it logs whatever the character touches. In my scene i have a object placed about 10m away from where the player capsule spawns, somehow it collides with it before you can even move.
Your code have an error. It logs "Touched pick" for every collision. To fix it, your should remove the semicolon in this line if(collision.gameObject.name == "Pickaxe" );
I have designed a scenario as below:
I created an object spawner to collide with things tagged as "ob", using a boolean to manage the timing to spawn new obstacles. Nonetheless, after some testing, I found that it seemed like nothing had ever collided with one another(Judged by the strings I put in the if condition had never shown in the console.) Can't figure out why! Please HELP!!!
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class newObSpawning : MonoBehaviour
{
public GameObject[] oblist;
private bool hasOb=true;
public float adjustSpawnx;
void Update()
{
if (!hasOb)
{
spawnObs();
hasOb = true;
}
}
private void OnTriggerEnter2D(Collider2D collision)
{
if (collision.gameObject.CompareTag("ob"))
{
hasOb = true;
Debug.Log("hasOb"); //just for testing
}
}
private void OnTriggerExit2D(Collider2D collision)
{
if (collision.gameObject.CompareTag("ob"))
{
hasOb = false;
Debug.Log("hasOb");
}
}
public void spawnObs()
{
int i = Random.Range(0, oblist.Length);
Debug.Log(i);
float y = 7.87f;
GameObject newob = Instantiate(oblist[i], new Vector3(transform.position.x+ adjustSpawnx,y,0), Quaternion.identity);
}
}
obspawner carry a "follow player" script to move at the same pace as the player,and it went just well
Your player doesn't seem to have a Rigidbody2D component. Add Rigidbody2D to your player. A collider can only emit OnTriggerEnter2D or OnTriggerExit2D events if there is a rigidbody on the object too
You have to tag the object "ob" that you want to register the collision with, most probably, I think what you are searching for is the collision of your player with object spawner so tag the player with "ob".
So i have this little particlesystem attached on my player so if he dies he explodes. But i cant simply attach the particlesystem under the player because if i destroy my player the childs of the gameobjects get destroyed as well. The animation runs if he dies but not on his current spot so some ideas for that? Maybe to transform the position to the current position of the player while he dies?
Here my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playerdeath : MonoBehaviour
{
public ParticleSystem death_explosion;
// Start is called before the first frame update
void Start()
{
death_explosion.Stop();
}
// Update is called once per frame
void Update()
{
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "deathcube")
Destroy(gameObject);
Debug.Log("collision detected");
death_explosion.Play();
}
}
What you could do is create a prefab of the particle object and reference it inside your script like so:
public ParticleSystem death_explosion_Prefab;
And instead of attaching it to the Player as a child, instantiate it on collision:
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "deathcube")
{
Debug.Log("collision detected");
Instantiate(death_explosion_Prefab, gameObject.transform.position, Quaternion.identity);
Destroy(gameObject);
}
}
got it :) --> add death_explosion.transform.position = GameObject.Find("player").transform.position;
I am trying to make the game go to Dead scene when collided by does not work. And it even does not detect the collsion.
I've attached the script to empty game object that has box collider with is trigger ticked and the player does have a Rigidbody too.
I am not sure what is wrong, please help.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class Health : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
public void OnCollisionEnter(Collision collision)
{
Debug.Log("dead without if statement");
if (collision.gameObject.tag == "Player")
{
Debug.Log("Dead Mate");
SceneManager.LoadScene("DeadScreen");
}
}
}
"I've attached the script to empty game object that has box collider with is trigger ticked and the player does have a Rigidbody too."
If i understand you correct you enabled trigger on box collider if yes you must implement
void OnTriggerEnter(Collider col)
{
}
Not
public void OnCollisionEnter(Collision collision)
{
}
