I’m certainly no expert when it comes to writing Flash classes, but here’s my question. Can you use operators on class members? I did a quick search on the web and only found information for C++ where it’s called “overloading operators” but I didn’t find anything about it in ActionScript. In case you’re curious why I’d like to use operators on a class, here’s what I was thinking…<\/p>\n

Let’s say I create 2 instances of the Point class:<\/p>\n

\/\/<\/span>
\nvar<\/span> a = new<\/span> Point(<\/span>1<\/span>, 2<\/span>)<\/span>;
\nvar<\/span> b = new<\/span> Point(<\/span>3<\/span>, 4<\/span>)<\/span>;
\n\/\/<\/span>
\n\/\/ I'd like to multiply point A by point B.<\/span>
\nvar<\/span> c = a *<\/span> b;
\n\/\/ Essentially saying:<\/span>
\n\/\/ c = new Point (3, 8);<\/span>
\n\/\/<\/span>
\n\/\/ I'd also like to multiply point A by a number.<\/span>
\nvar<\/span> d = a *<\/span> 6<\/span>;
\n\/\/ Essentially saying:<\/span>
\n\/\/ d = new Point(6, 12);<\/span>
\n\/\/<\/span><\/div><\/div>\n

Of course I’d also like to be able add, subtract and divide points. And while I’m at it, being able to use assignment operators such as +=, -=, \/= and *= would be nice too.<\/p>\n

Is this something that is supported in ActionScript 3? If not, do you think it will be? Do you think it should be?<\/p>\n
