= Projectile =
[[ArchivePage]]

  A Baseclass for all the Projectiles/Bullets that one might imagne.
  A Projectile is most of the Time emitted by a [wiki:Weapon Weapon]. 

__Dependecies__
  * [wiki:WorldEntity WorldEntity]
  * [wiki:Weapon Weapon]
  * !FastFactory


'''Projectiles''' get emitted by [wiki:Weapon Weapon]. ''Weapons'' give them their impuls, their live, and mainly all the essential __initial values__.
From there on, they are on their own, and fly through space searching for something to destroy and initiate the '''~''' operator ...
 * '''types''': 
   1. Rockets
   1. Lasers
   1. Projectiles (Metallic or Metalloplastic)
   1. Bombs
   1. Joining (like the linking-gun of some other games...)
   1. other doomsdaydevice-equal destruction Methods
   1. Zero Point Gravity/Black Hole

== Implementation ==
Here follows a listing of the most important Functions of this Class:
{{{
#!cpp
    void setFlightDirection(const Quaternion& flightDirection);
    void setVelocity(const Vector &velocity);
    void setLifeSpan(float lifeSpan);


    void setEnergies(float energyMin, float energyMax);

    /** @brief This is called, when the Projectile is Emitted */
    virtual void activate() = 0;
    /** @brief This is called, when the Projectile is being destroyed, or deleted */
    virtual void deactivate() = 0;

    virtual void destroy ();

    virtual void tick (float time);
    virtual void draw () const;
}}}

== Projectile Creation ==
Creating Projectiles is a rather easy process, but if you like, Projecties can be extremely extendable.
For instance, if you liked some Gravitation gun (not the one from HL2), then you would connect a physical field to the Gun, that sucks in all NPC's and if they are to near, distroy them (or damage them about some amount).

__Description__
  1. Have a look at the creation-howto of [wiki:WorldEntity WorldEntity]
  2. Make the class '''public [wiki:Projectile Projectile]''' instead of ''public [wiki:WorldEntity WorldEntity]'' (include projectile.h instead of world_entity.h)
  3. Graphics: probably the most important part about the creation of a Projectile -> OpenGL
  4. Special Actions, etc
