4.5.1 stable
I have Area2D with CollisionShape2D on my enemy, on my characteri only have CollisionShape2D, the collision and knockback work fine, except when the enemy touches the character from the top, then it gets glued to the character and even if the speed of character is higher it’s stuck.
Can you paste any relevant code from the enemy and character scripts?
You can add ```gdscript before and ``` after the pasted code to properly format it.
no sure which is relevant, but I have this inside enemy script:
func _on_area_2d_body_entered(body):
if body.is_in_group("player"):
var knockback_direction = (body.global_position - global_position).normalized()
if body.has_method("take_damage"):
body.take_damage(damage, knockback_direction)
and this inside players:
func _physics_process(_delta):
if not is_alive:
return
# movement
var move_direction = Vector2.ZERO
if Input.is_action_pressed("move_right"):
move_direction.x += 1
if Input.is_action_pressed("move_left"):
move_direction.x -= 1
if Input.is_action_pressed("move_down"):
move_direction.y += 1
if Input.is_action_pressed("move_up"):
move_direction.y -= 1
if move_direction.length() > 0:
move_direction = move_direction.normalized()
var total_velocity = move_direction * speed + knockback_vector
velocity = total_velocity
var input_direction = Input.get_vector("move_left", "move_right", "move_up", "move_down")
if input_direction.length() > 0:
last_fire_direction = input_direction.normalized()
elif Input.is_action_pressed("fire"):
last_fire_direction = (get_global_mouse_position() - global_position).normalized()
move_and_slide()
_update_animation(input_direction, last_fire_direction)
#knockback
knockback_vector *= knockback_decay
if knockback_vector.length() < 10:
knockback_vector = Vector2.ZERO
#test dmg
if Input.is_action_pressed("take_damage"):
take_damage(10)
func apply_knockback(direction: Vector2, force: float = 250.0):
if direction.length() > 0:
knockback_vector = direction.normalized() * force
func take_damage(damage_amount, knockback_direction: Vector2 = Vector2.ZERO):
if is_invincible or not is_alive:
return
print("took", damage_amount, " damage")
health -= damage_amount
print("health: ", health, "/", max_health)
#knockback
if knockback_direction.length() > 0:
apply_knockback(knockback_direction, 600.0)
#invincibility
is_invincible = true
$AnimatedSprite2D.modulate.a = 0.5
var timer = get_tree().create_timer(invincibility_time)
timer.timeout.connect(_end_invincibility)
if health <= 0:
die()

Character body properties, not area properties.
Also, enemy scene structure.
Motion modes for character bodies should be floating, not grounded
