The first problem you have is this:
onready var player = get_node("res://Player.tscn")
onready var player2 = get_node("res://Player2.tscn")
get_node() requires a node path, not a filename. res://Player.tscn is the file you’ve saved your player scene in.
get_node() needs to know where a node is in the Scene Tree. I don’t know what your tree looks like, so I can’t tell you what to put there.
I answered this exactly in your other question:
For example, if this was your tree:
Main (Node or Node2D)
– Player
– Enemy
Then in the enemy script you can reference the player by using get_node('../Player')
This is all covered in the Documentation. You really should go through the “Step by step” section, it will clear up a lot of this for you.
Ok - I changed the variables to
onready var player = get_node("Node2D/Player")
onready var player2 = get_node("Node2D/Player2"
but there is an error message that says “Invalid get index ‘position’ (on base: ‘null instance’)”
Any solutions? If needed, here is all of my code:
extends KinematicBody2D
onready var player = get_node("Node2D/Player")
onready var player2 = get_node("Node2D/Player2")
var velocity = Vector2()
var speed = 400
func _process(delta):
if player.position.x > position.x:
velocity.x += speed
if player.position.x < position.x:
velocity.x -= speed
if player.position.y > position.y:
velocity.y += speed
if player.position.y < position.y:
velocity.y -= speed
func _physics_process(delta):
velocity = move_and_slide(velocity * delta)

“Node2D/Player” is not the path of your player relative to the enemy. I even told you in my comment what to put:
get_node('../Player')
Node paths are relative to the calling node. When you put “Node2D/Player” you’re saying “look for a child of the enemy called ‘Node2D’ that has a child named ‘Player’”. However, that’s not where the player is. The player is a sibling of the enemy, so you need to go up one level ".." (which means the parent node) and then you can find Player. Are you familiar with folders on the computer? “…” means parent folder in the same way.

Thank you very much! I thought by “…Player” the “…” meant “what is before”. Thank you for that clarification!

I am faced with a new problem. I got my slime to follow my player’s x axis, but for some reason won’t follow the y axis. Here’s my code:
extends KinematicBody2D
onready var player = get_node("../Player")
var velocity = Vector2()
var speed = 5000
func _process(delta):
if player.position.x > position.x:
velocity.x += speed
if player.position.x < position.x:
velocity.x -= speed
if player2.position.y > position.y:
velocity.y += speed
if player2.position.y < position.y:
velocity.y -= speed
func _physics_process(delta):
velocity = move_and_slide(velocity * delta)
Nevermind - realized I was using the wrong variable!

New problem - I added states and animations, and for some reason, when the enemy needs to follow the player along the x axis, it gets very glitchy, constantly switching between all of the states. (note: it may be because the enemy is smaller than the player, and if so, how do I fix this without changing the size?) Any solutions? Here’s my code:
extends KinematicBody2D
onready var player = get_node("../Player")
var velocity = Vector2()
var speed = 5000
enum {RIGHT, LEFT, UP, DOWN, IDLE_RIGHT, IDLE_LEFT, IDLE_UP, IDLE_DOWN}
var anim
var new_anim
var state
func change_state(new_state):
state = new_state
match state:
RIGHT:
new_anim = 'right'
LEFT:
new_anim = 'left'
UP:
new_anim = 'up'
DOWN:
new_anim = 'down'
IDLE_RIGHT:
new_anim = 'idle_right'
IDLE_LEFT:
new_anim = 'idle_left'
IDLE_UP:
new_anim = 'idle_up'
IDLE_DOWN:
new_anim = 'idle_down'
func _ready():
change_state(IDLE_RIGHT)
func _process(delta):
if player.position.x > position.x:
velocity.x += speed
change_state(RIGHT)
if player.position.x < position.x:
velocity.x -= speed
change_state(LEFT)
if player.position.y > position.y:
velocity.y += speed
change_state(DOWN)
if player.position.y < position.y:
velocity.y -= speed
change_state(UP)
if new_anim != anim:
anim = new_anim
$AnimationPlayer.play(anim)
func _physics_process(delta):
velocity = move_and_slide(velocity * delta)

what was the wrong variable?
