Member Function Documentation

Object2D::Object2D()

Construct a 2D Object.

Object2D::~Object2D()

Destruct the object.

virtual long Object2D::add(Object* O) [virtual]

this checks to make sure that any Object added to a Object2D is derived from Object2D.

Returns -1 if dynamic_cast fails.

virtual long Object2D::calcGlobalPosition(int AllTheWay=0) [virtual]

Calculate the object's global position.

The global position is relative to the world, whereas the object's (local) position is relative to its parent. Non-zero AllTheWay means that the calculation will recursively go up the tree all the way to the root. Otherwise, the calculation will only go up one level.

virtual long Object2D::render(View& view) [virtual]

Render the sprite to the 2D view.

long Object2D::setPosition(fVector2D P)

Set the local (relative to parent) position.

Vector2D& Object2D::getGlobalPosition()

Retrieve the object's global position.

The global position is relative to the world, whereas the object's (local) position is relative to its parent.

virtual Vector2D Object2D::getSize() [virtual]

Retrieve the object's dimensions.

If a sprite is available, it will return its size, otherwize returns zero size.

fVector2D& Object2D::getPosition()

Retrieve the object's local position.

fVector2D Object2D::getMiddle()

Retrieve the mid point of the object.

This point is relative to the parent.

virtual Sprite* Object2D::getSprite() [virtual]

Retrieve the sprite associated with this object.

Implements the abstract SpriteSelector class method.

Reimplemented from SpriteSelector.

virtual long Object2D::collision(Collidable_Object* O) [virtual]

collision is called to indicate a collision between this and O.

It may return a RETCODE to indicate that it ('this' Object) should be removed/deleted.

virtual int Object2D::isCollision(Collidable_Object* O) [virtual]

called by CollisionDetection.

Determines if a collision occurred bewteen this and O

virtual int Object2D::isCollidable() [virtual]

called to determine if the Object is to participate in collision detection.

Default implementation returns non-zero if the sprite assigned to this is solid.
