Turn Prefab visible after colliding with an invisible object.,How to turn a prefab visible after collision with an invisible object?
I'm working in a proyect where i want a prefab to become visible after it has collide with an invisible object i have set at certain position in the screen. My problem is that is only seems to work with the latest copy of the prefab that i set, and the copies before that one no longer work. my prefab is a platform with the tag "Floor", the sprite renderer = false and a force going to the left, when it collides with my game object it turns the sprite renderer = true. and im using this code for my trigger gameobject
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Trigger : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
void OnTriggerEnter2D(Collider2D col){
if (col.tag == "Floor") {
GameObject.FindGameObjectWithTag ("Floor").GetComponent<SpriteRenderer> ().enabled = true;
}
}
}`
,I'm working on a proyect where i want a platform to become visible in a certain position in the screen, i have set an invisible object with this script in the position where i want the platforms to become visible. I have a prefab with the tag "Floor" and a force going to the left, so when it collides with my object the sprite renderer becomes true, the code seems to work properly on the first copy of the prefab i set, but not on the other copies of it. I don't really know what the problem is. pls help.
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Trigger : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
void OnTriggerEnter2D(Collider2D col){
if (col.tag == "Floor") {
GameObject.FindGameObjectWithTag ("Floor").GetComponent<SpriteRenderer> ().enabled = true;
}
}
}
You are calling FindGameObjectWithTag to get the object. That will find one object, not necessarily the one that hit your trigger.
I assume you want to effect only the one that hit the trigger. To do that, try changing the following line,,,
GameObject.FindGameObjectWithTag ("Floor").GetComponent<SpriteRenderer> ().enabled = true;
to
col.gameObject.GetComponent<SpriteRenderer>().enabled=true;
That should enable the SpriteRenderer component of the object that hit your trigger.
Hope this helps, -Larry
