Hellow, Is there any way i can generate downhills slopes? I played with your code a lot and i was only able to create uphills terrain, it seems changing number_hills to 1 and dividing j by 2 in hill_point.y gives you an uphills terrain. I would like downhills slopes but am unable to generate
Here are the code:
Terrain.gd
extends Node
export var num_hills = 1
export var slice = 10
export var hill_range = 100
var screensize
var terrain = Array()
var texture = preload("res://grass.png")
func _ready():
randomize()
screensize = get_viewport().get_visible_rect().size
terrain = Array()
var start_y = screensize.y * 3/4 + (-hill_range + randi() % hill_range*2)
terrain.append(Vector2(0, start_y))
add_hills()
func _process(delta):
if terrain[-1].x < $Runner.position.x + screensize.x / 2:
add_hills()
func add_hills():
var hill_width = screensize.x / num_hills
var hill_slices = hill_width / slice
var start = terrain[-1]
var poly = PoolVector2Array()
for i in range(num_hills):
var height = randi() % hill_range
start.y -= height
for j in range(0, hill_slices):
var hill_point = Vector2()
hill_point.x = start.x + j * slice + hill_width * i
hill_point.y = start.y + height * cos(2 * PI / hill_slices * j/2)
#$Line2D.add_point(hill_point)
terrain.append(hill_point)
poly.append(hill_point)
start.y += height
var shape = CollisionPolygon2D.new()
var ground = Polygon2D.new()
$StaticBody2D.add_child(shape)
poly.append(Vector2(terrain[-1].x, screensize.y))
poly.append(Vector2(start.x, screensize.y))
shape.polygon = poly
ground.polygon = poly
ground.texture = texture
add_child(ground)
