Load Children One at a Time

Question

Hi, I'd like to load each child of an object one at a time after an event has taken place. So far I'm only able to set the parent game object active but would like another effect, please help!

 void Start ()
 {
     _clickanddragscript._OnMouseUp = false;
     lineParent.SetActive(false);
 }
 
 void Update () {

     if (firstBar.transform.position != Vector3.zero)
     {
         Debug.Log("HasChanged");

         if (_clickanddragscript._OnMouseUp)
         {
             Debug.Log("Mose"); 
             firstBar.transform.DOMove(new Vector3(0, 10.9f), 2, false); 
             GetMyChildren(); 

         }
         
         // Wait 1 second 
         // Move the bar up 
         // Add some indication juice 
         // Load all the children of red lines parent object and wait a little between each load 
     }
     
 }

 void GetMyChildren()
 {
     foreach (Transform child in lineParent.transform)
     {

         for (int i = 0; i < barArray.Length; i++)
         {
         
             lineParent.SetActive(true);
                             // maybe do a coroutine 


         }
         
         
     }

     
 }

Instead of creating a function for GetMyChildren() you can make a coroutine. It'd be a much cleaner way of activating all your children one-by-one.

This function would activate one of lineParent's children after a certain delay of seconds; I believe this is the effect you want.

Here's an example of a way you could do so with an adjustable time delay:

 IEnumerator GetMyChildren(float delay)
 {
      lineParent.SetActive(true);
 
      foreach (Transform child in lineParent.transform)
      {
            yield return new WaitForSeconds(delay);
 
            child.SetActive(true);
      }
 }

If you wanted a delay of one second, for example, you could call the function in your 'if' statement in the Update function like this: StartCoroutine(GetMyChildren(1f));

Sorry if I misjudged what effect you wanted to achieve, if so, I'll fix my answer, just specify below in a comment.

Thanks @BDCakerules! This was helpful. The thing I noticed is that I had to change the child from a transform to a gameobject to set it active, but it didn't work so I did it manually instead and it worked!

IEnumerator NewGetMyChildren() {

     for (int i = 0; i < allMyChildren.Length; i++)
     {
         yield return new WaitForSeconds(delayTime);
         lineParent.SetActive(true);
         allMyChildren[i].SetActive(true);
     }
     
 }

@Smujukia, instead of changing the child you can just access its gameObject component with .gameobject: Ex:

allMyChildren[i].gameObject.SetActive(true);

This will work even if your children are transforms. If my answer helped, please mark it as correct! I'm happy you're getting the effect you want.
