It really feels good to find solutions for these challenges. There was a lot to do this time:

  • Put in variables for the size and a random min and max
  • Calculate the center starting position for Mr. Beardy
  • If the size changes Mr. Beardy needs to be moved accordingly. Because I instantiated him, the camera needs to be hooked up per script
  • And surprise, the borders won’t fit the new size, so they were also prefabbed and sized dynamically. I took a pencil and some paper to find the correct parameters for that.

Here is some of the interesting code:

    private void SpawnMisterBeardy() 
    {
        Vector2 beardyLocation = new Vector2(centerLocationX, centerLocationY);
        GameObject mrBeardy = Instantiate(playerPrefab, beardyLocation, Quaternion.identity);
        DestroyRocksAt(beardyLocation);

        cinemachineCamera.m_AnimatedTarget = mrBeardy.GetComponent<Animator>();
        cinemachineCamera.Follow = mrBeardy.transform;
    }

    private void SpawnBorders()
    {
        GameObject leftBorder = Instantiate(borderPrefab, Vector3.zero, Quaternion.identity);
        GameObject rightBorder = Instantiate(borderPrefab, Vector3.zero, Quaternion.identity);
        GameObject bottomBorder = Instantiate(borderPrefab, Vector3.zero, Quaternion.identity);
        GameObject topBorder = Instantiate(borderPrefab, Vector3.zero, Quaternion.identity);

        ResizeBorder(leftBorder, -1, (ySize/2f)-0.5f, 1, ySize);
        ResizeBorder(rightBorder, xSize, (ySize / 2f) - 0.5f, 1, ySize);
        ResizeBorder(bottomBorder, (xSize / 2f) - 0.5f, -1, xSize, 1);
        ResizeBorder(topBorder, (xSize / 2f) - 0.5f, ySize, xSize, 1);
    }

    private static void ResizeBorder(GameObject border, float offsetX, float offsetY, float sizeX, float sizeY)
    {
        border.GetComponent<BoxCollider2D>().offset = new Vector2(offsetX, offsetY);
        border.GetComponent<BoxCollider2D>().size = new Vector2(sizeX, sizeY);
    }

Please let me know what you think :slight_smile:

My solution was pretty similar to @MC_dev, but I left the existing borders in the game and just resized them at runtime. Probably cleaner to prefab them and instantiate, but it works. I created a separate script that I attached to the Border parent object in the hierarchy:

public class BorderScale : MonoBehaviour
{
    int gridLength;
    [SerializeField] public BoxCollider2D left;
    [SerializeField] BoxCollider2D right;
    [SerializeField] BoxCollider2D bottom;
    [SerializeField] BoxCollider2D top;
    // Start is called before the first frame update
    void Start()
    {
        var environment = FindObjectOfType<GenerateEnvironment>();
        var environmentScript = environment.GetComponent<GenerateEnvironment>();
        gridLength = environmentScript.gridLength;
        GenerateBorders(gridLength);
    }
    void GenerateBorders(int gridLength)
    {
        left.offset = new Vector2(-1,gridLength/2);
        left.size = new Vector2(1,gridLength+1);

        right.offset = new Vector2(gridLength,gridLength/2);
        right.size = new Vector2(1,gridLength+1);

        bottom.offset = new Vector2(-1,gridLength/-2);
        bottom.size = new Vector2(1,gridLength+1);

        top.offset = new Vector2(gridLength,gridLength/-2);
        top.size = new Vector2(1,gridLength+1);
    }
}
