#14 Vector type classes

[eRom]

Hi ;)

I looking your package about Vector type.
Interesting...but I think giving possibility to set or
get the 2 or 3 components for a vector with 1 method
could be useful, isn't it ?

For exemple in class Vector2D :
---------------------------------------------
public function setPosition(x:Number, y:Number) : Void {
setX(x);
setY(y);
}

public function getPosition(Void) : Object {
return { _x:getX(), _y:getY() };
}
---------------------------------------------
And the same for Vector3D with adding Z component ;)

Moreever we can use overloading for setting position
with another Vector or with 2 (or 3 for Vector3D) Numbers.

Exemple for Vector2D :
---------------------------------------------
public function setPosition() : Void {
var overload = new Overload(this);
overload.addHandler([Number], [Number],
setPositionByComponent);
overload.addHandler([Vector2D],
setPositionByComponent);
overload.forward(arguments);
}

private function setPositionByComponent(x:Number,
y:Number) : Void {
setX(x);
setY(y);
}

private function setPositionByVector(v:Vector2D) : Void {
setX(v.getX());
setY(v.getY());
}
---------------------------------------------

I think that theses classes are not finished..but it
could be cool to have some mathematics vector
operations, like addition, soustraction, opposite,
division, multiplication, scalar product....

Bye.

Vectors are some "not even half ready" product of a part
time developer of the as2lib. If i would implement it, it
would work with a array:
setPositionByCoordinates([x,y,z,....]); or
setPositionByVector(v:Vector); where it uses all the
available informations(in this way you could set the 2D
position of a 3D vector). Its been a long time since i have
learned about the operations but they might be interesting.
I try to figure out how to best solve this.
