Question get world position of tilemap

Hi,

what i want to do: I want to make my enemies know the tilemap parts near them (i want to do a spring system to make them keep a distance)

i would prefer to do this by using a collider attached to them (representing perception), which works totally fine for other gameobjects. But tilemaps only store the position of the tilemap gameobject (which then holds the array i used to create the tilemap). Maps might become big and may hold multiple enemies, thus i wanted the enemies only to check for elements close to them, instead of calculating springs for the whole map

solutions i can imagine:

• create gameobjects on the tilemap to register to the enemy perception -- this would somewhat make the usage of the tilemap redundant, because, as far as i understand, their purpose is to save gameobjects
• make the enemies access the tilemap array, transform it to world coordinates and manually check for close tiles -- this seems hacky
  
• make the enemies raycast in some angles around them and store the collision coordinate -- this might inaccurate, depending on the number of raycasts
• somehow get used to A* and hope that it can handle this

As you can see, the solutions i can come up with, do not seem that good to me and i would like to hear if anybody knows how to do this properly. thanks

 

sight, the method was looking for was WorldToCell(), thanks for reading anyway

 

I didn't know it, so good to know

 

glad i could help

full "solution" is

Code (CSharp):

1.  
2. public void OnCollisionEnter2D(Collision2D other)
3.  {
4.    Tilemap tilemap = other.gameObject.GetComponentInParent<Tilemap>();
5.  
6.    Vector3Int cellPosition = tilemap.WorldToCell(transform.position);
7.    Vector3 tilepos = tilemap.GetCellCenterWorld(cellPosition);
8. }

cellpos is the array element and tilepos the position of the tile in the world
