Simple In game search field

Archived Forums Questions & Answers

I have a few game objects that each have colliders. When I click the game object the console prints its name. Here is the script I have attached to each game object.

public void Start ()
	{
		string name = gameObject.name;
	}

	public void OnMouseDown()
	{
		Debug.Log(name);
	}

I also have a input field and a button that I currently can type in the name of a game object and destroy it.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEditor;

public class Search : MonoBehaviour
{	
	public Cube cube;
	public InputField Name;

	public void start ()
	{		
		GameObject selected = GameObject.Find (Name.text);
		Destroy (selected);
	}
}

Instead of Destroying the gameobject in the second script, how can I instead select the game objects collider as if I used OnMouseDown() from the first script; even more specifically How can I search the game object in the input field and “select” the gameobject as if I simple clicked on it by hand. This is what I am looking for:

     public void start ()
         {        
             GameObject selected = GameObject.Find (Name.text);
             Activate (selected); //activate the mesh collider to trigger     
                                               //OnMouseDown from first script. 
                                               //I know this  won't work, but I am not 
                                               // sure what the proper syntax is here.
         }

Very useful link, thanks !

The name string is a local variable. This means it can only be read / written by code in the method in which it was declared. You need to declare it oustide of any methods.

string name;

public void Start ()
     {
         name = gameObject.name;
     }
 
public void OnMouseDown()
     {
         Debug.Log(name);
     }

Also you can call OnMouseDown() from another script.

      public void start ()
          {        
              GameObject selected = GameObject.Find (Name.text);
              selected.OnMouseDown();
          }

Make a script that you will attach to your selectable objects, and have a function in it for selecting it, for example:

//script is, say, Selectable.cs

public void Select()
{
  //Do fancy stuff here - apply new graphics for selection, etc
}

Then, in your method where you fetch the input name:

public void Start()
{
      GameObject selected = GameObject.Find (Name.text);
    selected.GetComponent<Selectable>().Select();
}

The fancy part is fetching the component (script) of the targeted game object and calling it’s predefined function.

Note: I noticed you called your method “start”. If you wish it to execute at the start of the game, it needs to be called “Start”.
