Second possible mistake is, that your Debug.Log(familyArrayList) is hard coded to the first element. I think you might be confusing C# with Java or Javascript.Ĭhange your Java list to a C# list and add the type so that the compiler know that we intend to store Transform objects in this list (unless you intentions is to mix it with other types, but that is not recommended anyways because you might run into casting errors): public static List familyArrayList = new List() I'm truly stumped on this problem and thank anybody in advance who can point me in the right direction to solving this. Loop through all family array and set their values to null in grid as wellīut I get errors like 'Argument 1: cannot convert from 'object' to 'int'' and 'Non-invocable member 'Piece.familyArrayList' cannot be used like a method' which I can imagine are explained by my above problem of not storing the grid coordinates properly and instead storing the referenced game object. Should I instead use a nested list? At a later point in the code, I want to clear the game object from the board in world space as well as set the grid to null: // Loop through all family array and destroy game objects How can I get familyArrayList to properly story the grid coordinates and not the game object the grid coordinates are referencing? Output: Green Unit(Clone) (UnityEngine.Transform)

Go through game grid line by line and add game objects from game space into family ArrayList Public static ArrayList familyArrayList = new ArrayList() Here's the abridged code: private static Transform grid = new Transform I am attempting to push these coordinates into the nested list (familyList) to be deleted pending 3 or more units being added to familyArrayList (seen below). I have game objects tied to these coordinates in world space, with the grid syncing the data back in game space.

I'm building a match-3 game, and I currently have a multi-dimensional ArrayList holding transform coordinates on a grid of x width and y height. I am new to Unity game dev and trying to expand my knowledge of data structs.

Unity store data in grid
