unity c# find game object code example

Example 1: how to find gameobjects in unity

using UnityEngine;
using System.Collections;
// This returns the GameObject named Hand in one of the Scenes.
public class ExampleClass : MonoBehaviour
{
    public GameObject hand;    
    
    void Example()
    {
        // This returns the GameObject named Hand.
        hand = GameObject.Find("Hand");        
      
        // This returns the GameObject named Hand.
        // Hand must not have a parent in the Hierarchy view.
        hand = GameObject.Find("/Hand");     
      
        // This returns the GameObject named Hand,
        // which is a child of Arm > Monster.
        // Monster must not have a parent in the Hierarchy view.
        hand = GameObject.Find("/Monster/Arm/Hand");
        
        // This returns the GameObject named Hand,
        // which is a child of Arm > Monster.
        hand = GameObject.Find("Monster/Arm/Hand");
    }
}

Example 2: unity get component

using UnityEngine;

public class TryGetComponentExample : MonoBehaviour
{
    void Start()
    {
    	// Since Unity  2019.2 you can use TryGetComponent to check
        // if an object has a component, it will not allocate GC in 
        // the editor if the object doesn't have one.
        if (TryGetComponent(out Rigidbody rigidFound))
        {
        	// Deactivate rigidbody
            rigidFound.enabled = false;
        }
        
		// For versions below 2019.2 you can do it this way:
        // Create a variable
        Rigidbody rigidFound = GetComponent<Rigidbody>();
        
        // If the 'Rigidbody' exist in the gameobject
        if(rigidFound != null)
        {
        	// Deactivate rigidbody
            rigidFound.enabled = false;
        }
	}
}
