Weapon system

The script database_weapon.gd includes:

get_weapon(id: int) -> WeaponType reads the weapon database (json), initiates a WeaponType class and returns it.

Can create enemy system in similar fashion.

Bullet system

Bullet particle must be set to processing mode always.

Bullets detect hit with enemies and boxes by hurtbox, instead of by collision, which would cause the bullets to be removed before hitting the target.
