The set_cellv function returns the error “Invalid type in function ‘set_cellv’ in base ‘TileMap’. Cannot convert argument 2 from Nil to int”
Here is my code:
extends Node2D
const WIDTH = 500
const HEIGHT = 500
const TILES = {
‘grass’: 0,
‘water’: 1,
‘dirt’: 2,
‘tree’: 3,
‘bush’: 4
}
var grass_simplex_noise
var river_simplex_noise
func _ready():
randomize()
#Generate Seed
var Seed = randi()
#Create grass & bushes perlin map
grass_simplex_noise = OpenSimplexNoise.new()
grass_simplex_noise.seed = Seed
grass_simplex_noise.octaves = 4
grass_simplex_noise.period = 8
grass_simplex_noise.lacunarity = 2
grass_simplex_noise.persistence = 0.5
#Replace Tiles
_generate_world()
#Create River perlin worms
river_simplex_noise = OpenSimplexNoise.new()
river_simplex_noise.seed = Seed
river_simplex_noise.octaves = 1
river_simplex_noise.period = 1
river_simplex_noise.lacunarity = 1
river_simplex_noise.persistence = 1
#Replace Tiles
_generate_rivers()
func _generate_world():
for x in WIDTH:
for y in HEIGHT:
$TileMap.set_cellv(Vector2(x - WIDTH / 2, y - HEIGHT / 2), place_grass_and_bush(grass_simplex_noise.get_noise_2d(float(x), float(y))))
$TileMap.update_bitmask_region()
func place_grass_and_bush(noise_sample):
if noise_sample < 0.4:
return TILES.grass
return TILES.bush
func _generate_rivers():
for x in WIDTH:
for y in HEIGHT:
$TileMap.set_cellv(Vector2(x - WIDTH / 2, y - HEIGHT / 2), place_water(river_simplex_noise.get_noise_2d(float(x), float(y))))
$TileMap.update_bitmask_region()
func place_water(noise_sample):
if noise_sample < 0.7:
return TILES.water
The grass_simplex_noise works fine but the problem lies in the river_simplex_noise
Thank you in advance
