I have piece of code that using a tile set, i can draw an area of what is going to be a small town/city. The code seed_cities, make an X number of cities randomly on the map, whereas draw_city just paints the city over the screen.
My problem is that from time to time, 2 or more citites overlap in the map.
func seed_cities(num_cities):
var initial_point
var final_point
for i in range(0, num_cities):
initial_point = Vector2(int (rand_range(0, screen_size.x/10)), int (rand_range(0, screen_size.y/10)) )
range_x = randi() % 10 + 5 # 5 being minium longitude
range_y = randi() % 10 + 5 # 5 being minium longitude
final_point = Vector2(range_x, range_y)
var city_position = {
initial_point: initial_point,
final_point: final_point
}
cities.append(city_position)
# TODO check if there is another city before
draw_city(final_point,final_point)
now, i tried to use the function line_intersects_line_2d , but the appears an error saying that line_intersects_line_2d is not declared on the current class, so i have another method of checking if the cities overlap. i was thinking of using that or creating an area2D with code to check if there is a collision.
func draw_city(initial_point, final_point):
for x in range(0,final_point.x):
$Objects.set_cell(initial_point.x + x , initial_point.y,4)
$Objects.set_cell(initial_point.x + x, initial_point.y + final_point.y,4)
for y in range(0,final_point.y+1):
$Objects.set_cell(initial_point.x, initial_point.y + y,4)
$Objects.set_cell(initial_point.x + final_point.x, initial_point.y +y,4)
Any ideas on what i need to import to use line_intersects_line_2d? What other way i can check if 2 cities overlap before saving it's position and draw them on the map?
