Get all GameObjects by variable value

Question

I am making a level editor where player is inserting GameObjects into scene. Each GameObject is created with script that has public groupId variable. Player can change the groupId value to whatever int value he wants. The problem is, I don't know how to get the GameObjects with the same groupId to put them into ArrayList.

you can use a Dictionary to make this first make an array with this gameobject.. then create a foreach loop and use :

 //think that your Dictionary's var name is myDict and you groupId is in groupId script and variable is named as groupId and your gameobject array is sceneObjects[]
 
 foreach(GameObject go in sceneObjects){
 myDict.Add(go.GetComponent<groupId>().groupId,go);
 }

then you can call your gameobject like this :

 //34824 is groupId
 myDict[34824]

you use system.collections.generic and you can create like this :

 private Dictionary<int,GameObject> sceneObjects = new Dictionary<int,GameObject>();
