I’m trying to make my enemy die animation run when it collides with a certain area of my player and the function is called however it states that I have an invalid call to nonexistent function ‘travel’ in base nil, here is my code for the player:
extends KinematicBody2D
var state_machine
const UP = Vector2(0,-1)
const GRAVITY = 20
const ACCELERATION = 50
const MAX_SPEED = 200
const JUMP_HEIGHT = -550
var motion = Vector2()
var enemy
func _ready():
state_machine = $PlayerAnimationTree.get("parameters/playback")
state_machine.start("Idle")
enemy = preload("res://Prefabs/Snake_Enemy.gd").new()
func _physics_process(delta):
motion.y += GRAVITY
var friction = false
if Input.is_action_pressed("ui_right"):
motion.x = min(motion.x + ACCELERATION, MAX_SPEED)
state_machine.travel("Walking")
$Sprite.scale.x = -0.1
get_node("ColLeft").set_disabled(false)
get_node("ColRight").set_disabled(true)
elif Input.is_action_pressed("ui_left"):
motion.x = max(motion.x - ACCELERATION, -MAX_SPEED)
state_machine.travel("Walking")
$Sprite.scale.x = 0.1
get_node("ColLeft").set_disabled(true)
get_node("ColRight").set_disabled(false)
elif Input.is_action_just_pressed("ui_accept"):
state_machine.travel("Attack")
else:
friction = true
state_machine.travel("Idle")
if is_on_floor():
if Input.is_action_just_pressed("ui_up"):
motion.y = JUMP_HEIGHT
if friction == true:
motion.x = lerp(motion.x, 0, 0.2)
else:
if motion.y > 0:
state_machine.travel("Jump")
if motion.y < -50:
state_machine.travel("Fall")
else:
state_machine.travel("Fall")
if friction == true:
motion.x = lerp(motion.x, 0, 0.05)
motion = move_and_slide(motion, UP)
pass
func attack():
state_machine.travel("Attack")
func die():
state_machine.travel("Die")
func _on_TongueHit_area_entered(area):
if area.get_name() == "HurtBox":
enemy.Dead()
area.get_parent().call_deferred("queue_free")
print("Enemy Die")
Here is the code for the enemy
extends KinematicBody2D
# CONSTANT VARIABLES
const GRAVITY = 20
const SPEED = 200
const FLOOR = Vector2(0, -1)
# VARIABLES
var velocity = Vector2()
var direction = 1
var state_machine
var is_dead = false
# FUNCTIONS
func _ready():
state_machine = $AnimationTree.get("parameters/playback")
state_machine.start("Idle")
func _physics_process(delta):
if is_dead == false:
velocity.x = SPEED * -direction
if direction == -1:
$Walk.scale.x = -0.1
else:
$Walk.scale.x = 0.1
Walk()
velocity.y += GRAVITY
velocity = move_and_slide(velocity, FLOOR)
if is_on_wall():
direction = direction * -1
$RayCast2D.position.x *= -1
if $RayCast2D.is_colliding() == false:
direction = direction * -1
$RayCast2D.position.x *= -1
func Dead():
state_machine.travel("Die")
is_dead = true
velocity = Vector2(0,0)
print("DIE")
func Walk():
state_machine.travel("Walk")
func Idle():
state_machine.trave("Idle")
func Attack():
state_machine.travel("Attack")
