[C#] attach GameObject as a children to another GameObject

I have been working with this for hours looking at all kinds of suggestions on the net and in this forum but not got this to work. I am very new to Unity and C# so i am still learning. I guess i am still a bit hooked to how this is done in Objective-C and SpriteKit.

This is the scenario:

I use this piece of code to catch all objects on a specific location.

Code (csharp):

1. RaycastHit2D[] hits = Physics2D.LinecastAll(clickedPos,clickedPos,theLayer);

I use the following code to create an empty "container" (GameObject) that i want too use as the parent:

Code (csharp):

1. // Create a container for the selected sprites using the ContainerObject prefab
2. containerGO = Resources.Load("ContainerObject") as GameObject;
3. containerGO.tag = "Container";
4. containerGO.transform.position = hits[0].transform.position; // Set position at clicked object
5. Instantiate(containerGO);

I then have been reading and tested all kinds of things to try to move the selected raycast-"hits" to become a child to containerGO but not succeeded. I am aware that i need to care about the direct link to the prefab, got an error message, but just can't figure out how to properly do this.

The following is the code i am currently use and it does not work:

Code (csharp):

1. //>>>>>>TESTING<<<<<<//
2.  
3. foreach(RaycastHit2D theChild in hits) {
4.     string theChildName = theChild.transform.tag + "(Clone)"; //(Clone) is for the prefabs that are currently on the game board
5.  
6.     dummyGameObject = GameObject.Find(theChildName);
7.  
8.     gameObjectList.Add(dummyGameObject);
9. }
10.  
11. //The 'gameObjectList[1]' is just to test with a predefined object in hits so I do not need to iterate
12. Transform aChildPiece = gameObjectList[1].transform;   //containerGO.transform; // This is parent node
13.  
14. GameObject clone = Instantiate(aChildPiece, transform.position, transform.rotation);
15.  
16. clone.transform.parent = containerGO.transform;
17.  
18. //>>>>>>TESTING<<<<<<//

I need all help i can get :-(

 

parenting is done via the Transform Component

theChild.transform.parent = containerGO.transform;

 

I tried that:

Code (csharp):

1. clone.transform.parent = containerGO.transform;

 

Im not sure what you are doing incorrect then as this is how its done. I've done it hundreds of times without any problems. Are both objects in the scene? can you see them there?

Edit :


Also what error are you mentioning , if the runtime throws an error in a script it could cause other pieces of code to not execute..

 

Thanks shaderbytes for the help

uhhh I am not very good at this...

I solved it by placing this code on the object:

Code (csharp):

1. void OnLongPress(LongPressGesture gesture) {
2.         print ("Here we go - " + MainScript.selectedGameObjectList.Count);
3.  
4.         firstRound = true;
5.  
6.         // Allocate all selected objects to the container
7.         foreach(GameObject aGameObject in MainScript.selectedGameObjectList) {
8.             print ("aGameObject: " + aGameObject.name);
9.             if(firstRound) {
10.                 // At the first round do not add child as the first object is parent
11.                 print ("The first round" + aGameObject.name);
12.                 theFirstGO = aGameObject;
13.  
14.                 firstRound = false;
15.             }
16.             else {
17.                 // Add to parent
18.                 //print ("The other rounds: " + aGameObject.name);
19.  
20.                 aGameObject.transform.parent = theFirstGO.transform;
21.                 aGameObject.collider2D.enabled = false;            
22.             }
23.         }
