Tilemap Player destroy tile on contact
I am looking for information about how to use the more advanced options on a tile map. What I am trying to find is help with destroying one tile a time from tilemap. The game player is a farmer ploughing a field, a green tile map, as he ploughs the green tile needs to change to brown(mud). Can someone point me in the direction of some tutorial so I can learn how to do this. Would prefer not a youtube video but if that is the only option I will use.
I fiddled around a little and made this little script. Add it to the tilemap and set Destroyed Tile to the tile you want to be displayed. The Tilemap must have a Tilemap Collider 2D on it as well. Then click the mouse on the tilemap when playing the game to see the effect in action.
using UnityEngine;
using UnityEngine.Tilemaps;
public class TilemapDestroyer : MonoBehaviour
{
// How destroyed tiles should look.
public TileBase destroyedTile;
Tilemap tilemap;
void Start()
{
tilemap = GetComponent<Tilemap>();
}
void Update()
{
if (Input.GetMouseButton(0))
{
// Mouse pos to tile pos
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit2D hit = Physics2D.Raycast(ray.origin, ray.direction);
Vector3Int pos = tilemap.WorldToCell(hit.point);
// Replace tile with destroyed tile
tilemap.SetTile(pos, destroyedTile);
}
}
}
