Hello, I’ve got problem with this piece of code that’s supposed to find empty tiles by looping through the cells of a 32x32 tilemap:

const gridWidth = 32
const gridHeight = 32

var tilemap = get_parent().get_node("TileMap")

for x in range(gridWidth):
	for y in range(gridHeight):
		var tile_index = tilemap.get_cell(gridWidth, gridHeight)
		print(tile_index)

The tile_index variable always ends up with the value of 1, even though I’ve got plenty of other type of tiles, also empty ones.

However if I print try printing tile indexes with constant values like this:

print(tilemap.get_cell(7,9));

Then it prints the correct -1 value.

What could be the problem?

You are getting always the same tile index with

var tile_index = tilemap.get_cell(gridWidth, gridHeight) #the const/limit values

It should be

var tile_index = tilemap.get_cell(x, y)

This kind of things happens to everybody ^^;

Thanks a lot!
