Make 2048 in Unity – Linked Lists (Lesson 4)

For this lesson, we will be setting up the relationship between the cells of our 2048 grid and the fill block prefabs. This is in preparation for when we start moving and combining the blocks. To create the relationships we will be using somewhat of a linked list except our will be more of a quad linked list.

public class Cell2048 : MonoBehaviour
{
    public Cell2048 right;
    public Cell2048 down;
    public Cell2048 left;
    public Cell2048 up;
}

Fill2048.cs

using System.Collections.Generic;

using UnityEngine.UI;
public class Fill2048 : MonoBehaviour
{
    public int value;
    [SerializeField] Text valueDisplay;
    public void FillValueUpdate(int valueIn)
    {
        value = valueIn;
        valueDisplay.text = value.ToString();
    }
}
