Example

const BULLET_SCENE: PackedScene = preload("res://.../bullet.tscn")
var bullet_speed: float = 300


func shoot(target: CharacterBody2D) -> void:
	var to_target: Vector2 = target.global_position - global_position

	var bullet_velocities: Array[Vector2] = BDC.velocities_vector2(bullet_speed, to_target, target.velocity)

	if bullet_velocities.size() == 0:
		print("impossible to hit the target")
		return

	var bullet: CharacterBody2D = BULLET_SCENE.instantiate()
	bullet.global_position = global_position
	bullet.velocity = bullet_velocities[0]

	get_parent().add_child(bullet)
