Adding a GameObject to a LIST at On_TouchStart, .position changed later without any interaction

Before a drag & drop of an object i am "trying" to save a copy of the GameObject in a List to preserve it's position vs. it's parent GameObject (that is dragged). I then want to compare the two.

I do the following:

1. I have a "On_TouchStart", which register the first touch to the GameObject. In this function i save the GameObject into a List. During tests i have tested to first copy the original to another GameObject etc. That is what you see in the code below.

2. I then do the drag, use in the "selected_GameObject" only, not the one saved in the LIST.

3. At "On_DragEnd" i print the record in the actual LIST and the position i get is the end position, not the one the GameObject had when i added it to the LIST. I do NOT access the LIST in between.

Here is the result of the process (print) at "On_TouchStart":

Code (csharp):

1.  
2. "GO at touch: HQB || TOUCH START POS: (-0.3, -2.2, 51.0)"
3. "LIST at touch: HQB || TOUCH START POS: (-0.3, -2.2, 51.0)"
4. Both is reflecting the starting position
5.  

Here is the result of the process (print) at "On_DragEnd":

Code (csharp):

1.  
2. "selected_GameObject at END: HQB || TOUCH END POS: (3.2, 4.3, 51.0)"
3. "LIST at END: HQB || TOUCH END POS: (3.2, 4.3, 51.0)"
4. The position in the LIST has changed??
5.  

Here are extracts from the code:

Code (csharp):

1.  
2. //Catches object at first finger down
3. void On_TouchStart( Gesturegesture) {
4.  
5.     if (fingerSelectionIsActive == false) { //If finger DrawSelection is active do not process
6.  
7.       if (gesture.pickObject != null) {
8.          temp_CardDeck_GameObject_List = DoTheLinecast();
9.  
10.             if ( temp_CardDeck_GameObject_List.Count < 1 ) {
11.                selected_GameObject = gesture.pickObject;
12.             }
13.             else {
14.                selected_GameObject = temp_CardDeck_GameObject_List[0];
15.             }
16.  
17.             temp_CardDeck_GameObject_List.Clear ();
18.  
19.             if ( templateMode ) {
20.                firstPosTemplate_GameObject = selected_GameObject;
21.               SaveTemplateScript.theTemplateStaticDeck_GameObject_List.Add(firstPosTemplate_GameObject);
22.  
23.               print ("GO at touch: " + firstPosTemplate_GameObject.tag + " || TOUCH START POS: " +       firstPosTemplate_GameObject.transform.position);
24.               print ("LIST at touch: " + SaveTemplateScript.theTemplateStaticDeck_GameObject_List[0].tag + " || TOUCH START POS: " +    SaveTemplateScript.theTemplateStaticDeck_GameObject_List[0].transform.position);
25.           }
26.        }
27.     }
28.  }
29.  

Extract from the drag code, the LIST is never touched between "On_TouchStart" and "On_DragEnd".

Code (csharp):

1.  
2. void On_DragEnd( Gesturegesture) {
3.    if ( templateMode ) {
4.       Singleton.Instance.master_GameObject_List = RefreshSortOrderAndZandPutObjectOnTop (Singleton.Instance.master_GameObject_List, selected_GameObject);
5.       print ("selected_GameObject at END: " + selected_GameObject.tag + " || TOUCH END POS: " + selected_GameObject.transform.position);
6.       print ("LIST at END: " + SaveTemplateScript.theTemplateStaticDeck_GameObject_List[0].tag + " || TOUCH END POS: " + SaveTemplateScript.theTemplateStaticDeck_GameObject_List[0].transform.position);
7.    }
8.  
9.    if (fingerSelectionIsActive == false) { //If fingerDrawSelection is active do not process
10.       if (container_GameObject_List.Count == nrOfCardsInTheGame) {
11.  
12.       float theX = container_GameObject_List[0].transform.position.x;
13.       float theY = container_GameObject_List[0].transform.position.y;
14.  
15.       //Save container x & y position to playerPrefs
16.       PlayerPrefs.SetFloat("deck_X", theX);
17.       PlayerPrefs.SetFloat("deck_Y", theY);
18.  
19.       EndMultiIconStatus(); //End without the need to click on icon
20.     }
21.    }
22.  }
23.  

I have tested with a local LIST as well, gives the same result.

 

You are using a reference to a GameObject not a copy. If you want to duplicate the GameObject you have to use Instantiate(), but probably is better if you just save only the data you need in a list (eg: transform.position).

 

Uhhhh i must have got brain damage and spent hours to get it :-( ...unbelivable

Thanks
