Question about tiles
Hello guys, im creating a game inspired by a mod from Warcraft 3 called warlocks. Im making the game in 2d with free sprites from the asset store. Currently im trying to make a ground that gets "destroyed". 
Im swapping the green tiles with the red tiles(they are seperate tilemaps), so it looks like im destroying the ground. But I only managed to swap only the top side of the tilemap. Code below:
private Tilemap tilemap;
private int xValue;
private int yValue;
public Tile lava;
// Start is called before the first frame update
void Start()
{
//get the big red tilemap
tilemap = GetComponent<Tilemap>();
//x and y in the tilemap should always be uneven, so that the (0,0) position of the tilemap is always in the middle
//The -1 is the (0,0) position on the tilemap
xValue = (tilemap.size.x - 1) / 2;
yValue = (tilemap.size.y - 1) / 2;
//Invoking the GroundDestroy method with no wait time, then repeating every second.
InvokeRepeating("GroundDestroy", 0.0f, 1.0f);
}
//Method to destroy the ground
private void GroundDestroy()
{
//This starts at the top of the tilemap, and goes down until it reaches the middle, in other words y=0
for (int x = -xValue; x <= xValue; x++)
{
if (yValue > 0)
tilemap.SetTile(new Vector3Int(x, yValue, 0), lava);
else
//Canceling the invoke after half the ground is destroyed
CancelInvoke();
}
yValue--;
Debug.Log("Ground is shrinking!");
}
My goal is to swap the tiles(the green ones of course) on all four side simultaneously, and I dont know how to do that. Any help will be much appreciated. Thank you for your time.
Your current loop currently iterates from -(width-1) to width-1. This is not what you want.
You want either:
4 loops, each removing a line from one of the side.
A function that takes a position and removes all the squares on that line/column, that is then called on the corners.
A function that decides from the coordinates if a square should be removed or not, and run it on every square, using a nested loop.
Try to think about each line you want to remove, and what defines them.
