How to fix autotile

aimless-skipper

I have an autotile set up that works perfectly fine if I make a map using the tilemap in the editor, however I am making a game with procedural generation and when I set the tiles with code it always displays the first tile in the autotile, regardless of the bitmask. how can i fix the autotile so it shows up properly when tiles are set with code?

It might help if you actually posted your code here.

This is the code:

extends TileMap

var generation = OpenSimplexNoise.new()

func generate(x_pos,y_pos,w,h):
	for x in range(w):
		for y in range(h):
			set_cell(x_pos+x,y_pos+y+(generation.get_noise_1d(x))*20,0)

func _ready():
	randomize()
	generation.seed = randi()
	generate(-30,50,600,60)

Found out about update_bitmask_region(), it works great now
