How can I add the OnTriggerEnter function to all game objects that I instantiate?
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class GasolineScript : MonoBehaviour { public GameObject Gasoline; public GameObject Coin; int n = 0, moveSpeed = 6, ok; float aux1,aux2; bool isMoving = false; Vector2 dir, pos; GameObject gasoline; Rigidbody2D gasolineRB; BoxCollider2D gasolineCol;
void Start()
{
SpawnCoins();
}
void Update()
{
if (isMoving)
{
gasolineRB.MovePosition(gasolineRB.position + dir * moveSpeed * Time.fixedDeltaTime);
}
if (Input.GetMouseButtonDown(0))
{
gasoline = Instantiate(Gasoline, new Vector2(-2.7f , 0.1f), Quaternion.Euler(0f, 0f, 180f)) as GameObject;
pos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
isMoving = true;
gasoline.AddComponent<Rigidbody2D>();
gasolineRB = gasoline.GetComponent<Rigidbody2D>();
gasolineCol=gasoline.GetComponent<BoxCollider2D>();
dir = (pos - new Vector2(-2.7f, 0.1f) ).normalized;
}
//rotation
transform.eulerAngles = new Vector3(0, 0, n);
n++;
}
void SpawnCoins()
{
aux1 = Random.Range(-3.9f, -1.55f);
aux2 = Random.Range(-0.9f, 0.9f);
ok = 1;
for(;ok==1;)
{
ok = 0;
if((aux1>=-3f && aux1<=-2.4f) && (aux2<=0.4f && aux2 >= -0.2))
{
ok = 1;
}
if (ok == 1)
{
aux1 = Random.Range(-3.9f, -1.55f);
aux2 = Random.Range(-0.9f, 0.9f);
}
}
GameObject coin= Instantiate(Coin, new Vector2(aux1,aux2), Quaternion.identity) as GameObject;
}
void OnTriggerEnter2D(Collider2D collider)
{
if (collider.gameObject.tag == "Coin")
{
Destroy(collider.gameObject);
SpawnCoins();
}
if (collider.gameObject.tag == "Border")
{
Destroy(gameObject);
}
}
}
You could make a script with the OnTriggerEnter method and add that to the GameObject after instantiating it.

To further my comment here is an example OnTriggercomponent script and its usage.
Example OnTriggerEnterComponent
public class OnTriggerEnterComponent : MonoBehaviour
{
public string ActionableTag { get; set; }
private void OnTriggerEnter2D(Collider collision)
{
if (collision.CompareTag(ActionableTag))
{
// Do Something
}
}
}
Demo of its usage
public class Demo : MonoBehaviour
{
public GameObject prefab;
private void Start()
{
GameObject go = Instantiate(prefab, Vector3.zero, Quaternion.identity);
go.AddComponent<BoxCollider2D>();
go.GetComponent<BoxCollider2D>().isTrigger = true;
go.AddComponent<OnTriggerEnterComponent>().ActionableTag = "Player";
}
}
Also as you can see i changed it to use CompareTag as it is more efficient., Hope this helps.
