Hello everyone! How I can use the fill on tilemap with code?

Question

How I can use the fill with code? It is like set_cell

I want to fill a white islands, because I vant to separate their on continents

[Locher]

Although I have no idea how the code is, I assume it would be the following:

• Loop through each used cell in the tilemap
• Check if the cell is of ID = white island
• cell.modulate = Color.whateveryouwant

The code could be something like this

for tile in tilemap.get_used_cells(0): # I assume the cells are on layer0
	var tiledata = tilemap.get_cell_tile_data(0, tile)
	if tiledata == # however you distinguished the white islands
		tiledata.modulate = Color.YELLOW # or something

I don’t understood “tiledata==”. I checked, if tile is land, then simply set a white color

if get_cell_atlas_coords(0, tile_position) in list_land_tiles:
	list_continens_tiles.append(tile_position)
	set_cell(4, tile_position, 2, Vector2i.ZERO)

Does this do what you want it to do?

if get_cell_atlas_coords(0, tile_position) in list_land_tiles:
	list_continens_tiles.append(tile_position)
	set_cell(4, tile_position, 2, Vector2i.ZERO)

	var cell = get_cell_tile_data(4, tile_position)
	cell.modulate = Color.WHITE

Thank you for your help, but i get
(cell.modulate = Color.YELLOW)

I understood how do it

var t = 1
	for tile in list_continens_tiles:
		if get_cell_atlas_coords(4, tile) == Vector2i(0, 0):
			fill_continents(tile, Vector2i(t, 0))
			t += 1

func fill_continents(pos : Vector2i, colot_tile : Vector2i):
	var stack = [pos]
	var visited = []
	while stack.size() > 0:
		var position = stack.pop_back()
		# Проверяем, если тайл уже был посещен
		if position in visited:
			continue
		# Заменяем текущий тайл на новый
		set_cell(4, position, 2, colot_tile)
		# Получаем соседние тайлы
		for offset in list_vectors:
			var neighbor_position = position + offset
			if get_cell_atlas_coords(4, neighbor_position) == Vector2i(0, 0):
				stack.append(neighbor_position)
