The ArmedEntity class is the base class of all armed entities in the game. Armed entities are those who can fire some missiles.

This class is derived from the AEntity interface and add some methods to manage the missiles.

Public member functions

// Construct a new Armed Entity object
ArmedEntity(Room &room, u_int id, short x, short y, short w, short h);
// Construct a new Armed Entity object
ArmedEntity(Room &room, u_int id, const std::pair<short, short> &pos, const std::pair<short, short> &size);
// Refresh the entity (move, shoot, etc.)

Protected member functions

// Refresh the missiles of the entity (move, delete, etc.)
virtual void refreshMissiles();
// Check if any missile of the entity collide with another entity
virtual bool missilesCollide(const IEntity &other);
// Fire a new missile

Member functions documentation

Constructor

The constructor of the ArmedEntity class.

ArmedEntity(Room &room, u_int id, short x, short y, short w, short h);
ArmedEntity(Room &room, u_int id, const std::pair<short, short> &pos, const std::pair<short, short> &size);

Parameters

  • room: A reference to the room in which the entity is.

  • id: The id of the entity.

  • x: The x position of the entity.

  • y: The y position of the entity.

  • w: The width of the entity.

  • h: The height of the entity.

  • pos: A pair of short containing the position of the entity (x, y).

  • size: A pair of short containing the size of the entity (w, h).

refresh

See IEntity::refresh.

refreshMissiles

This method refreshes all the missiles of the entity (move, delete, etc.). It is principally called by the refresh method.

virtual void refreshMissiles();

missilesCollide

This method checks if any missile of the entity collide with another entity. It is principally called by the collide method.

virtual bool missilesCollide(const IEntity &other);

Parameters

  • other: A reference to the other entity to check collision with.

Returns

A boolean which is true if any missile of the entity collide with the other entity, false otherwise.

fireMissile

This method fires a new missile. It is principally called by the refresh method.

virtual void fireMissile(Missile::Type type);

Parameters

  • type: The type of the missile to fire.

Attributes documentation

_lastFire

The last time the entity fired a missile. This attribute is used to manage the fire rate of the entity, and is principally used by the refresh method.
