How to arrange list

Question

Hello,

I have two lists:

 var PosList : List.<float>;
 var ObjList : List.<GameObjects>;

I want to arrange the first list, and the second list to be arranged accordingly to the first one.

For example:

 //list one contains:
 [3]
 [1]
 [2]
 
 //list two contains gameObjects with the names:
 [number3]
 [number1]
 [number2]
 
 //I sort the first list, so I use:
 PosList.Sort();
 
 //Now the first list became:
 [1]
 [2]
 [3]
 
 //How can I arrange the second list to mach the first one? //Like t$$anonymous$$s:
 [number1]
 [number2]
 [number3]

You could use some LINQ like t$$anonymous$$s:

 ObjList = ObjList.OrderBy(x => int.Parse(x.transform.name.Replace("number", ""))).ToList();

You should better use Dictionary<float, GameObject>. So once you call Sort, it will be sorted as per the key. Or you can try custom sorting procedures.

Also, there is a possibility to use SortedDictionary.

Using dictionary you don;t have to be precise about the value on each index, once the key sorted there corresponding value will be moved in the same way.

Hope you will not see t$$anonymous$$s problem then.

 [Serializable]
 public class PositionedGameObject
 {
     public GameObject gameObject;
     public float gameObjectPosition;
 }
 
 // Later...
 
 public List<PositionedGameObject> positionedGameObjects;
 
 // Event later...
 
 positionedGameObjects.Sort(ComparePositionedGameObjectByWhateves);

What you have: you store a list of multi-purpose "complex" objects (a game object and its associated position) in a distributed manner in two lists w$$anonymous$$ch causes desyncing on top of being very unintuitive.
What you actually want: create a class/struct that describes an object and its position together. Store a list of instances of that class/structure. Vuala, now try to have them unsynced. You can't.
