How To Find Child Object and set is own criteria??

[Satish004]

I m working On 2d game…

i create a empty gameobject and store a multiple child object

i applid a different different tag on child game object but chile tag was not found???

Referance:

Game Object: ObstacleScript.cs

Obstacle Object :

MoveFast Object Image :

Vertical Rotate Object Image :

Code:

Obstacle.cs // Put Script On GameObject

   void Update()
    {
        goTopToDown();
    }

    void goTopToDown()
    {
            //transform.position += Vector3.down * speed * Time.deltaTime;  

              //find with tag and move top to down object   ex: 8 object should be slow move top to down
            if(gameObject.tag== "obstacleobject")                     
            { 
                transform.position += Vector3.down * speed * Time.deltaTime;            
                Debug.Log("GameObject Name:" + gameObject.tag);
                Debug.Log("inside vertical object");
            }

            //find with tag and Vertical Rotate object           //ex:  1 game  object should be rotate left to right
            if (gameObject.tag == "verticalrotateobject")  
            {
                transform.Rotate(Vector3.forward, turnSpeed * rotatesped * Time.deltaTime);    
                transform.position += Vector3.down  * speed * Time.deltaTime;                       //move top to down
                Debug.Log("GameObject Name:" + gameObject.tag);
                Debug.Log("inside vertical object");
            }

             //find with tag and move fast object        ex: 2 object is speed is very fast
            if (gameObject.tag == "movefastobject") 
            {
                transform.position += Vector3.down * movefastobjectspeed * Time.deltaTime
                Debug.Log("GameObject Name:" + gameObject.tag);
                Debug.Log("inside movefast object");
            }
 }



  void OnTriggerEnter2D(Collider2D other)  // i want to when three tag  gameobject collided with my player then trigger fire
    {
            foreach (Transform child in transform)                      
            {
                if (child.tag == "obstacleobject" || child.tag == "movefastobject" || child.tag == "verticalrotateobject") 
                {
                    Debug.Log("chiildtag:" + child.tag);
                    gameovertext.SetActive(true);
                     
                    StartCoroutine(gameover());
                    Debug.Log("inside triggerfire");
                }
        }

But issue is i not found my child tag???

You are just checking if the parent object has the tag. Instead, you need to cycle through all the parents children and see if they have the tag. Something like this:

–

    private void goTopToDown()
    {
        foreach(Transform trans in transform)
        {
            if (trans.tag == "obstacleobject")
            {

            }
            else if (trans.tag == "verticalrotateobject")
            {

            }
            else if (trans.tag == "movefastobject")
            {

            }
        }
    }

i made some modifications to your code try this

void Update()
{
	goTopToDown();
}

void goTopToDown()
{
	//transform.position += Vector3.down * speed * Time.deltaTime;  
	//find with tag and move top to down object   ex: 8 object should be slow move top to down
	foreach (GameObject item in GetComponentsInChildren<GameObject>())
	{
		if (item.tag == "obstacleobject")
		{
			transform.position += Vector3.down * speed * Time.deltaTime;
			Debug.Log("GameObject Name:" + gameObject.tag);
			Debug.Log("inside vertical object");
		}
		//find with tag and Vertical Rotate object           //ex:  1 game  object should be rotate left to right
		if (item.tag == "verticalrotateobject")
		{
			transform.Rotate(Vector3.forward, turnSpeed * rotatesped * Time.deltaTime);
			transform.position += Vector3.down * speed * Time.deltaTime;                       //move top to down
			Debug.Log("GameObject Name:" + gameObject.tag);
			Debug.Log("inside vertical object");
		}
		//find with tag and move fast object        ex: 2 object is speed is very fast
		if (item.tag == "movefastobject")
		{
			transform.position += Vector3.down * movefastobjectspeed * Time.deltaTime


				 Debug.Log("GameObject Name:" + gameObject.tag);
			Debug.Log("inside movefast object");
		}
	}
}

void OnTriggerEnter2D(Collider2D other)  // i want to when three tag  gameobject collided with my player then trigger fire
{
	foreach (Transform child in GetComponentsInChildren<Transform>())
	{
		if (child.tag == "obstacleobject" || child.tag == "movefastobject" || child.tag == "verticalrotateobject")
		{
			Debug.Log("chiildtag:" + child.tag);
			gameovertext.SetActive(true);

			StartCoroutine(gameover());
			Debug.Log("inside triggerfire");
		}
	}
