I’m a new Unity user.

To make my scene perform better, I have switched the mesh renderer off for objects that don’t necessarily need to be seen.

However, when the player enters a collider, I want those objects (assigned the tag “Appear”) to have their meshes rendered so that they may become visible.

using UnityEngine;
using System.Collections;

public class RenderTrig : MonoBehaviour {
	void OnTriggerEnter(Collider other) {
		GameObject Appear = GameObject.Find("Appear");
		(Appear).GetComponent<MeshRenderer>().enabled=true;
		}
}

I tried to create what I thought would do the trick, called the script RenderTrig, and placed it on my collider, which I named TRIGGIFER. I know, however, that I’m doing something fatally wrong, but I don’t know where my mistake lies. What do I need to do?

Thanks for your help in advance!

You told that “Tag” not “Name”.
;

GameObject.Find("GameObjectName");

Will Find An Object That It’s name is “GameObjectName”
You can use this.

  GameObject.FindGameObjectWithTag("MyTag");

Get an array of all objects with the tag “Appear”. For each item in the array, set the mesh renderer to enabled = true.

public class NameOfYourTriggersClass : MonoBehaviour {
	public GameObject[] visibleList;

	void OnTriggerEnter(Collider other) {
		//here's the script you need to create an array of gameobjects with tag: Appear
		if (visibleList == null) {
			visibleList = GameObject.FindGameObjectsWithTag("Appear");
		}
		//set each object's Mesh Rendere to enabled that appears in the list
		foreach (GameObject visible in visibleList) {
			visible.GetComponent<MeshRenderer>().enabled=true;
		}
}

Haven’t tested that but it should work as long as the trigger is actually triggering. Might get some errors or warning for not using the Collider of the triggering object.
