Question
Hi, so I’ve been searching everywhere and trying to figure out how to make my spider enemy work like a spider, aka walk on floors and walls. I’ve currently turned off all gravity and change the walking script to be moving in both x and y and still the enemy does not walk up the wall. I’ve also toggled the Motion mode Floating, set wall min slide angle to 0 and added walls to be detected.
Currently the enemy has 2 patrol points set on top of both walls that are surrendering it and all it does is go towards the wall on the left and just keeps walking in the direction of the wall never going up it.
here are the properties and code:
extends CharacterBody2D
var enemy_death_effect = preload("res://Enemies/enemy_death_effect.tscn")
@export var patrol_points : Node
@export var speed : int = 1500
@export var wait_time : int = 2
@export var health_amount : int = 3
@export var damage_amount : int = 1
@onready var animated_sprite_2d = $AnimatedSprite2D
@onready var timer = $Timer
enum State { Idle, Walk }
var current_state : State
var direction : Vector2 = Vector2.LEFT
var number_of_points : int
var point_positions : Array[Vector2]
var current_point : Vector2
var current_point_position : int
var can_walk : bool
func _ready():
if patrol_points != null:
number_of_points = patrol_points.get_children().size()
for point in patrol_points.get_children():
point_positions.append(point.global_position)
current_point = point_positions[current_point_position]
else:
print("no patrol points bro")
timer.wait_time = wait_time
current_state = State.Idle
func _physics_process(delta: float):
enemy_idle(delta)
enemy_walk(delta)
move_and_slide()
enemy_animations()
func enemy_idle(delta : float):
if !can_walk:
velocity.x = move_toward(velocity.x, 0, speed *delta )
current_state = State.Idle
#moving_sound.play()
func enemy_walk(delta: float):
if !can_walk:
return
if abs(position.x - current_point.x) > 0.5:
velocity.x = direction.x * speed * delta
current_state = State.Walk
#activation_sound.play()
if abs(position.y - current_point.y) > 0.5:
velocity.y = direction.y * speed * delta
current_state = State.Walk
else:
current_point_position += 1
if current_point_position >= number_of_points:
current_point_position = 0
current_point = point_positions[current_point_position]
if current_point.x > position.x:
direction = Vector2.RIGHT
if current_point.y > position.y:
direction = Vector2.UP
if current_point.y < position.y:
direction = Vector2.DOWN
else:
direction = Vector2.LEFT
can_walk = false
timer.start()
animated_sprite_2d.flip_h = direction.x > 0
animated_sprite_2d.flip_v = direction.y > 0
func enemy_animations():
if current_state == State.Idle && !can_walk:
animated_sprite_2d.play("idle")
elif current_state == State.Walk && can_walk:
animated_sprite_2d.play("walk")
func _on_timer_timeout():
can_walk = true
func _on_hurtbox_area_entered(area : Area2D):
print("hurtbox entered")
if area.get_parent().has_method("get_damage_amount"):
var node = area.get_parent() as Node
health_amount -= node.damage_amount
print("Health amount:", health_amount)
if health_amount <= 0:
var enemy_death_effect_instance = enemy_death_effect.instantiate() as Node2D
enemy_death_effect_instance.global_position = global_position
get_parent().add_child(enemy_death_effect_instance)
queue_free()
Finally just to cover all points of interest my Tilemap is setup like this:
