Hey i’m trying to make a 2d game (top down shooter) where maps is procedural generated, also enemies are placed in randomly in x,y locations within the enemy spawn range.
Here is the code and image of nodes connected for Main_a.tscn
extends Control
const FLOOR = -1
const WALL = 0
var noise
var flooro_cap = 1
var floori_cap = Vector2 (0.3, 0.1)
const gridSize = Vector2(160,80)
const gridSize_floor = Vector2(80,50)
var diggers = []
onready var tilemapo = $Mapo
onready var tilemapi = $Mapi
onready var tilemapj = $Map
var num = 5
var amount = 0
var enemySpawnrange = Vector2(2490,1530)
onready var enemy_container = get_node("enemy_container")
onready var enemy1 = preload("res://enemies/Enemy1.tscn")
func _ready():
load_game()
func load_game():
randomize()
gen_map()
make_flooro_map()
$Player.position = map.world_center() + Vector2.ONE * 16
set_process(true)
spawn_enemy(num)
func spawn_enemy(num):
var rand = RandomNumberGenerator.new()
for i in range(num):
var enemy = enemy1.instance()
enemy_container.add_child(enemy)
enemy.connect("enemy_spawn_amount", self, "_on_enemy_spawn_amount")
rand.randomize()
var x = rand.randf_range(0, enemySpawnrange.x)
rand.randomize()
var y = rand.randf_range(0, enemySpawnrange.y)
enemy.set_position(Vector2(x, y))
func _on_enemy_spawn_amount():
amount += 1
print(amount)
func _process(delta):
if Input.is_action_just_pressed("ui_accept"):
get_tree().reload_current_scene()
_ready()
elif Input.is_action_just_pressed("ui_cancel"):
get_tree().quit()
if enemy_container.get_child_count() != num:
var rand = RandomNumberGenerator.new()
for i in range(amount):
var enemy = enemy1.instance()
enemy_container.add_child(enemy)
enemy.connect("enemy_spawn_amount", self, "_on_enemy_spawn_amount")
rand.randomize()
var x = rand.randf_range(0, enemySpawnrange.x)
rand.randomize()
var y = rand.randf_range(0, enemySpawnrange.y)
enemy.set_position(Vector2(x, y))
amount -= 1
func gen_map()
........
func make_flooro_map():
.......
Here is the code and image of node within the Enemy1.tscn
extends Area2D
signal enemy_spawn_amount
func _ready():
pass
func _on_Enemygrunt_body_entered(body):
if body.get_name() == "Player":
print("player")
elif body.get_name() == "Mapo":
print("mapo")
emit_signal("enemy_spawn_amount")
queue_free()
I haven’t mentioned any parameters or code for map generation to make the code short and readable.
So this is how the enemy spawns work. First the map is randomly generated from the center of the gridsize box . and player sprite is placed. enemySpawnrange is set to Vector2(2490,1530) which is almost as same as map size gridSize = Vector2(160,80).
Then spawn_enemy(num) spawns enemies randomly around the map, it also checks _on_Enemygrunt_body_entered(body): function in Enemy1.gd using signals. if the enemy is making contact with Mapo tile map (outside the boundary of randomly generated map) it is queue_free() and is deleted.
The amount is recorded in this function and is used in the _process(delta) function. This loops until amount = 0. there by spawning all enemies inside the randomly generated map.
I feel like there is something wrong with my code, and will cause problems once i start implementing enemy movement .
Is there a better way of spawning enemies, the current method i’m using takes about 10 seconds minimum to put all 5 enemies inside the generated map ( for a 2d game 10 seconds is a pretty long time for loading).
Reducing the spawn boundary would definitely help in placing enemies faster. But i don’t know how to change the location spawn range rectangle.one point of the spawn range rectangle is fixed to the top left corner of the screen. and it only scales or shrinks based on that fixed point.
Also enemies are placed one after the another, is there any way i could place them all at the same time.
