Hi!
I have a TileMap node with 3 types of tiles (let them be a, b, c). When I click on the screen I want to change the tile on which I have clicked with another one. I don’t have any idea about it. Can anyone please help me. Thank you in advance!

You can use TileMap.world_to_map for your mouse click get_global_mouse_position() to get to the cell value using TileMap.get_cellv()

var tilemap = $TileMap

var mouse :Vector2 = get_global_mouse_position()
var cell :Vector2 = tilemap.world_to_map(mouse)
var abc :int = tilemap.get_cellv(cell)
var new_abc :int = (abc + 1) % 3 # just an example plus 1 modules 3
tilemap.set_cellv(cell, new_abc)

Thanks!
But how will I change cell value?

How to find out the cell value

I’m assuming you’re asking how to find what value to input into the set_cell function to get the cell you want placed? You can look in the tileset editor for that information.
