Godot3で花火模様を描いて一時停止し、プレイヤーをゆっくり狙う弾

幾何学模様を描いて停止

動き出す時に、プレイヤーを狙う

幾何学模様を描く処理だけ書けば、既存の仕組みの組み合わせただけ

code:py

extends EnemyBase

export(int) var bullet_speed = 55

export(int) var spread_num = 22

export(int) var bullet_num = 15

export(int) var stop_time = 5

onready var use_bullet = preload("res://Scenes/Bullets/E_Bullet_red_6x6.tscn")

func _shoot(player):

# 幾何学模様を描いた後、しばらく停止してからプレイヤーを狙って動く

var direction_list = []

var rand_direction = Vector2(floor(rand_range(-1, 1)), floor(rand_range(-1, 1)))

if rand_direction == Vector2.ZERO:

rand_direction = Vector2.ONE

for i in spread_num + 1:

direction_list.push_front(rand_direction.rotated(i * (PI * 2 / (spread_num + 1))))

for i in bullet_num:

for direction in direction_list:

var bullet = use_bullet.instance()

bullet.is_stop = true

bullet.speed = bullet_speed

bullet.dir = (player.global_position - global_position).normalized()

var timer := Timer.new()

timer.connect("timeout", bullet, "_on_stop_timer_timeout")

timer.wait_time = stop_time

timer.one_shot = true

timer.autostart = true

bullet.add_child(timer)

_add_bullet_to_root(bullet)

bullet.position += (5 * direction) * (i+1) + direction.rotated(PI/7) * sin(PI/8 * i) * 25

yield(get_tree().create_timer(.01), "timeout")
