Question
Hi! I am trying to generate a map using Simplex Smooth noise and I get very random artifacts when generating trees.
Here’s a screenshot (red is for errors and blue to show that they do not happen all the time):
I am not exactly sure why this is happening since only some of the tiles are causing trouble.
I will provide a code snippet below if it helps:
func generate_trees():
var small_distance = false
for y in range(height):
for x in range (width):
if y >= 2:
var noise_val = noise_base.get_noise_2d(x,y)
var coords_tocheck = Vector2(x, y-2)
var validity = false
if !trees_busy_coords.has(coords_tocheck):
var rng_spawn = randi_range(1,30)
if rng_spawn > 3:
pass
else:
if noise_val <= min_noise + one_percent_noise_diff*50:
pass
elif noise_val <= min_noise + one_percent_noise_diff*70:
tilemap.set_cell(3,Vector2(x,y), source_id_base, tree_big_green_atlas_A)
validity = true
elif noise_val <= min_noise + one_percent_noise_diff*90:
tilemap.set_cell(3,Vector2(x,y), source_id_base, tree_big_green_atlas_B)
validity = true
else:
tilemap.set_cell(3,Vector2(x,y), source_id_base, tree_big_green_atlas_C)
validity = true
if validity == true:
var free_tree_cells = 1
for cell in free_tree_cells:
no_grass_coords[Vector2(x,y)] = true
var no_trees_area
var rng
if small_distance == false:
rng = randi_range(3,6)
else:
rng = randi_range(4,6)
if rng == 2:
small_distance = true
rng = randi_range(3,6)
no_trees_area = rng
for cell_x in range(-no_trees_area, no_trees_area):
for cell_y in range(-2, 2):
var new_coords = Vector2(x + cell_x, y + cell_y -2)
trees_busy_coords[new_coords] = true
I’d appreciate any help or just a general direction to research.
Cheers!
