Operator overloading

[KuroiLight]

Operator Overloading is it supported? I didn't see anything on the Objects page. I'm trying to do something like the following:

Code: Select all

Class Point {
    __New(x, y) {
        this.x := x, this.y := y
    }

    ==(p) {
        return (p.x == this.x and p.y == this.y)
    }

    -(p) {
        return new Point(this.x - p.x, this.y - p.y)
    }
}

P1 := new Point(150, 150)
P2 := new Point(200, 100)

P3 := P1 - P2
MsgBox, % P3.x . " " . P3.y

Anything like you mentioned is not supported.

Code: Select all

P3 := P1 - P2

You can't subtract one object from another. But you could achieve what you want by another way:

Code: Select all

Class Point {
    __New(x, y) {
        this.x := x, this.y := y
    }

    Compare(p)  {
        return (p.x == this.x and p.y == this.y)
    }

    Decrement(p) {
        return new Point(this.x - p.x, this.y - p.y)
    }
}

P1 := new Point(150, 150)
P2 := new Point(200, 100)

MsgBox, % P1.Compare(P2)

P3 := P1.Decrement(P2)
MsgBox, % P3.x . " " . P3.y

Yea, that's what I ended up doing.
I was mostly curious if there was a some special way of doing this that may have been somewhere else in the docs (that i somehow missed), I've encountered strange ways of operator overloading in other languages in the past.
