print(grid_map.area_get_name(1))

Error: Condition’area_map.has(p_area)'is true. returned: “”

What does this p_area?

Do you want to get an area or cell?

I don’t know how the area thing works, but if is a cell item name, to obtain it get the name from the MeshLibrary with get_item_name

Thanks!

		var cell = get_node('ray_niz').get_collider().get_cell_item(self_pos[0]-0.5, self_pos[1]-1.5, self_pos[2]+0.5)
		print(get_node('ray_niz').get_collider().get_theme().get_item_name(cell))

edit:

cell = get_node('ray_niz').get_collider().get_cell_item(round(self_pos[0]), round(self_pos[1]-1), round(self_pos[2]))

To get the name of a cell item, MeshLibrary has the get_item_name method, using a valid index.

For an item index at specific location, use GridMap get_cell_item with GridMap coordinates (not global/local translation).

Respect to Gridmap areas (those that can be “painted” with the editor), I don’t know the use, seems to be related to portals and rooms.
