Question
I am following this tutorial and have run into a situation where an instanced bullet scene is colliding with regular level geometry and a general CollisionShape3D node but not CollisionShape3D nodes I’ve set up for the skeleton. The bullets just fly right through the enemy mouse’s head, even after I increased the size of the head collision shape.
All parent individual Area3D node for each CollisionShape3d is grouped as “enemy” and linked to a script to handle the BodyParts and a “body_part_hit” signal. I have also checked the documentation and triple checked my code and that the collision masks on the raycast of the bullet.tscn are compatible. I am completely stumped.
Bullet Script
extends Node3D
const SPEED: float = 40.0
@onready var mesh = $MeshInstance3D
@onready var ray = $RayCast3D
@onready var particles = $GPUParticles3D
# Called when the node enters the scene tree for the first time.
func _ready() -> void:
pass # Replace with function body.
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
position += transform.basis * Vector3(0, 0, -SPEED) * delta
if ray.is_colliding():
mesh.visible = false
particles.emitting = true
ray.enabled = false
if ray.get_collider().is_in_group("enemy"):
ray.get_collider().hit()
await get_tree().create_timer(1.0).timeout
queue_free()
func _on_timer_timeout() -> void:
queue_free()
Enemy Script
extends CharacterBody3D
var player = null
var state_machine
var health: int = 6
const SPEED : float = 4.0
const ATTACK_RANGE : float = 2.5
@export var player_path : NodePath
@onready var nav_agent = $NavigationAgent3D
@onready var anim_tree = $AnimationTree
# Get player node path
func _ready() -> void:
player = get_node(player_path)
state_machine = anim_tree.get("parameters/playback")
# Determine enemy pathing
func _process(delta: float) -> void:
velocity = Vector3.ZERO
match state_machine.get_current_node():
"Run":
# Navigation
nav_agent.set_target_position(player.global_transform.origin)
var next_nav_point = nav_agent.get_next_path_position()
velocity = (next_nav_point - global_transform.origin).normalized() * SPEED
rotation.y = lerp_angle(rotation.y, atan2(-velocity.x, -velocity.z), delta * 10.0)
"Punch":
look_at(Vector3(player.global_position.x, global_position.y,
player.global_position.z), Vector3.UP)
# Conditions
anim_tree.set("parameters/conditions/attack", _target_in_range())
anim_tree.set("parameters/conditions/run", !_target_in_range())
anim_tree.get("parameters/playback")
move_and_slide()
func _target_in_range():
return global_position.distance_to(player.global_position) < ATTACK_RANGE
func _hit_finished():
if global_position.distance_to(player.global_position) < ATTACK_RANGE + 1.0:
var dir = global_position.direction_to(player.global_position)
player.hit(dir)
func _on_area_3d_body_part_hit(dam):
health -= dam
if health <= 0:
queue_free()

,then when I followed further in videos , started scripting for conditions for “attack” and “run”, my zombie just yeet away from player. Now I just deleted the Zombie.tcsn
