How to stop my enemies from joining forces as a single unit?

Nerdzmasterz

I just made my baddies today. I set them to collide with the player and not themselves- and next thing you know, I have ten enemies in the exact same position, forming what looks like a single sprite.

I set the enemies to collide with each other next, and some work, and others spawn on top of each other and rapidly spin around the player as they chase it.

Now I have no idea what to do. Please help?

I'm trying to go for them avoiding each other, and moving closer to the player once the one(s) in front of them move or die, instead of literally climbing on top of each other. The enemies are kinematic2D bodies with a collision shap, a sprite, and an area2D with a collision shape to represent the attack range. The only reason I used kinematic2D was because I found a script for that to make the enemy look at and chase the player.

The enemies will eventually also have a line of sight, most likely from a raycast, and a wandering stage in their script. The script will fire the attack stage upon spotting the player or its things.

I think it's time to start using the raycast. First to stop the enemy when it gets too close to another or even the player. For spawning, you can either spawn in one location and use a timer so the enemy has time to move, or test the spawn area to make sure it's clear.

One thing you could consider is having the enemies move to a random(ish) position near the player instead of all going to the same spot.

Technically, I'm already spawning them randomly. I have no idea how to check if the area already has an enemy in it, however.

func spawn_zombies():
	for z in zombie_count:
		var zombie_basic = Zombie_Basic.instance()
		add_child(zombie_basic)
		var x_range = Vector2(100, 400)
		var y_range = Vector2(100, 400)
		var random_x = randi() % int(x_range[1]- x_range[0]) + 1 + x_range[0] 
		var random_y =  randi() % int(y_range[1]-y_range[0]) + 1 + y_range[0]
		var random_pos = Vector2(random_x, random_y)
		position=random_pos

You can just use an area a little larger than the character. First place the area, check for an overlap with an enemy or the player, then place the enemy there if there is no overlap. You might need to wait a frame, I'm not sure. I've never tried it.

This is the weirdest bug ever.

So I switched the "World" node from being the spawner to having a new node, zombie_spawner, to be what creats them randomly. It works... sort of? I could probably fix most of this bug by having the zombies not automatically chasing the player, but to do so whenever the player enters the raycast... but check out this bug.

One of the zombies, for some weird reason, doesn't chase the player, and instead spins around it at a hundred miles an hour. It's the one that is wandering sideways. All of the other spawned ones work. Only one of them is originally in the game to keep the game from saying the zombies can't find the player node, and that is not the weird one.

And, I'm guessing I'm not the only one who would love to spawn random enemies, so... Here's the code that I have so far:

var x_range
var y_range
 
var timer

func _init():
	move_to()
	timer = Timer.new()
	add_child(timer)
	timer.autostart = true
	timer.wait_time = 0.1
	timer.connect("timeout", self, "_timeout")

func _ready():
	randomize()

func _timeout():
	spawn_zombie()

func spawn_zombie():
	var zombie_basic = Zombie_Basic.instance()
	add_child(zombie_basic)


func _on_ZombieSpawner_body_entered(body):
	move_to()


func move_to():
	var x_range = Vector2(100, 400)
	var y_range = Vector2(100, 400)
	var random_x = randi() % int(x_range[1]- x_range[0]) + 1 + x_range[0] 
	var random_y =  randi() % int(y_range[1]-y_range[0]) + 1 + y_range[0]
	var random_pos = Vector2(random_x, random_y)
	position=random_pos


func _on_Player_start_day():
	_init()

This is weird. Apparently, if the buggy zombie is hit by one of the others, he works? :/

Here's the enemy code:

extends KinematicBody2D

var velocity = Vector2()
var DeathIndex = 2
onready var can_attack = true
var timer
var is_touching = false


func _ready():
	randomize()
	timer = Timer.new()
	add_child(timer)
	timer.wait_time = 1
	

func _physics_process(_delta):
	var Player = get_node("../Player")
	position += (Player.position - position) / 35
	look_at(Player.global_position)

	 
# warning-ignore:return_value_discarded
	move_and_slide(velocity)
func _on_Area2D_body_entered(body):
	if "Bullet" in body.name:
		DeathIndex -= 1
		 
	if DeathIndex == 0:
		queue_free()
		 
	 

func start_timer():
	timer.start()

func _on_AttackArea_body_entered(body):
	if body.name == "Player":
		is_touching = true
		can_attack = true
		attacking()
		start_timer()


func _timeout():
	can_attack = true
	attacking()
	start_timer()


func attacking():
	if can_attack == true && is_touching == true:
		can_attack = false
		var Blood = preload("res://Blood.tscn")
		var blood = Blood.instance()
		get_node("../Player").add_child(blood)

func _on_AttackArea_body_exited(body):
	if body.name == "Player":
		is_touching = true
		timer.stop()

The enemies look at the player now. Here's the new code.

extends KinematicBody2D

var velocity = Vector2()
var DeathIndex = 2
onready var can_attack = true
var timer
var is_touching = false
var dir

var target = null
const SPEED = 3000


func _on_Area2D_body_entered(body):
	print(body.name)
	if body.name == "Player":
		target = body
	elif "Bullet" in body.name:
		DeathIndex -= 1
		 
	if DeathIndex == 0:
		queue_free()
		 
	 
func _on_Area2D_body_exited(body):
	if body.name == "Player":
		target = null
func _ready():
	randomize()
	timer = Timer.new()
	add_child(timer)
	timer.wait_time = 1
	

func _physics_process(delta):
	target = get_node("../Player")
	#if target:
	var velocity = global_position.direction_to(target.global_position)
	#position of player minus enemy position will give us direction
	dir = target.position - position

	#get angle from direction (Note roation is in radians)  
	get_node("Sprite").rotation = dir.angle()
	move_and_slide(velocity * SPEED * delta)
		

func start_timer():
	timer.start()

func _on_AttackArea_body_entered(body):
	if body.name == "Player":
		is_touching = true
		can_attack = true
		attacking()
		start_timer()


func _timeout():
	can_attack = true
	attacking()
	start_timer()


func attacking():
	if can_attack == true && is_touching == true:
		can_attack = false
		var Blood = preload("res://Blood.tscn")
		var blood = Blood.instance()
		get_node("../Player").add_child(blood)

func _on_AttackArea_body_exited(body):
	if body.name == "Player":
		is_touching = true
		timer.stop()
