I recently making AI behaviour for my FPS project, and I managed to make my enemy to chase my player character if player got too far away from enemy AI, and enemy AI will take cover by moving to the specific cover area if my player character move close enough to any of those enemies.
But I only managed to make them to use one cover area by moving toward it. I can make more individual cover area in the same scene and refer them separately in enemy AI script, but this will be inconvenient and may not work as I intended, as I want my enemy only choose to move to nearby cover.
Is there a way to group cover area and refers that group in enemy AI script?
Btw, here is my enemy AI code:
enum {IDLE, ALERT, CHASE, COVER}
var state = IDLE
var target = null
onready var cover_area = get_node("../CoverPoint") # get node called coverpoint
func _physics_process(delta: float) -> void:
...
change_states(delta)
func _on_DetectionArea_body_entered(body):
if body.name == "Player":
target = body
state = COVER
func _on_DetectionArea_body_exited(body):
if body.name == "Player":
if body.is_queued_for_deletion():
target = null
state = IDLE
func change_states(delta : float) -> void:
match state:
...
CHASE:
Chase(delta)
COVER:
Covering(delta)
func Chase(delta : float) -> void: # Chase player once get far away from enemy
look_at(target.global_transform.origin, Vector3.UP)
direction = (target.global_transform.origin - global_transform.origin).normalized()
Gravity_velocity(delta)
func Covering(delta : float) -> void: # Will seek for cover and shoot at player if close enough
if global_transform.origin.distance_to(cover_area.global_transform.origin) > 1:
direction = (cover_area.global_transform.origin - global_transform.origin).normalized()
else:
direction = Vector3()
look_at(target.global_transform.origin, Vector3.UP)
Gravity_velocity(delta)
func Gravity_velocity(delta : float) -> void:
...
elif state == CHASE:
velocity = velocity.linear_interpolate(direction * acrobatics.mov_spd,
acrobatics.accel * delta)
if !attack_timer.is_stopped():
attack_timer.stop()
if global_transform.origin.distance_to(target.global_transform.origin) < rush_dist:
state = COVER
elif state == COVER:
velocity = velocity.linear_interpolate(direction * acrobatics.mov_spd,
acrobatics.accel * delta) # direction towards nearby cover instead of target
if attack_timer.is_stopped():
attack_timer.start()
if global_transform.origin.distance_to(target.global_transform.origin) > rush_dist:
state = CHASE
