this is my code, it fires a raycast from the camera and in the direction the player is looking. the problem is that this raycast only detects hitting an enemy if the enemy has nothing behind them. if there is a wall behind them, the raycast either hits the wall, or if the wall is exlcuded via collision_mask then the raycast hits nothing.
func fire_functional_bullet(dir: Vector3, damage: int) -> Dictionary:
var space_state := get_world_3d().direct_space_state
var query := PhysicsRayQueryParameters3D.create(
global_position,
global_position + (dir * RAY_LENGTH),
collision_mask
)
query.collide_with_areas = true
query.hit_from_inside = true
var result = space_state.intersect_ray(query)
if not result: return result
if result.collider is not Health: return result
result.collider.hit(self, damage)
return result
i know it is firing in the correct direction and that the enemy successfully recieves damage when result.collider is an enemy. i am using csg nodes and Health extends Area3D (which is why query.collide_with_areas = true)
the collision masks i have are World, Player, and Enemies. i want and did have the raycast using World + Enemies, but it would detect the wall if there was one behind the enemy. im not sure godot cares what my collision masks are though, because when i set the raycast to just Enemies then it detects nothing if there is a wall behind the enemy.
the collision mask is set to an @export var under BulletManager
extends Node3D
class_name BulletManager
const RAY_LENGTH: float = 4000
# This is set to just Enemies layer in inspector
@export_custom(PROPERTY_HINT_LAYERS_3D_PHYSICS, "") var collision_mask: int = 1
func fire_functional_bullet(dir: Vector3, damage: int) -> Dictionary:
var space_state := get_world_3d().direct_space_state
var query := PhysicsRayQueryParameters3D.create(
global_position,
global_position + (dir * RAY_LENGTH),
collision_mask
)
query.collide_with_areas = true
query.hit_from_inside = true
var result = space_state.intersect_ray(query)
if not result: return result
if result.collider is not Health: return result
result.collider.hit(self, damage)
return result
# not much for now, but later ill add visual bullet
func fire_bullet(dir: Vector3, damage: int) -> void:
fire_functional_bullet(dir, damage)
ive printed result, thats how i know its hitting the wall behind the enemy if there is one. even with the wall excluded via collision mask it prints nothing
