Hi all,

I'm trying to expose my Point class to AngelScript, so that it can be used like so:

// This works
Point aPos;
aPos.x=50;
aPos.y=50;

// This doesn't
Point aAnotherPos=Point(1,1);

So first part, no problem... the second part keeps telling me no matching signatures to Point with int, int.

But I do have this:

aResult=gEngine->RegisterObjectMethod("Point","Point &opAssign(const int, const int)", asFUNCTION(AssignPointII),asCALL_GENERIC);

Am I going about this entirely the wrong way?

Yes, you're going about this the wrong way. Your opAssign() method needs to be passed a "const Point &in" instead of 2 integers, since that's what you're setting it to in your script.

When I do that, it only tells me that no matching signatures exist for Point(const int, const int) exists.

When I embed this directly in the script:

class Point
{
    float x,y;
};

All the assignments, and equals, and comparisons things work perfectly.  How can I get this behavior so that it uses my point class factory instead?

I mean instead of doing:

Point &opAssign(const int, const int)

You should do this instead:

Point &opAssign(const Point &in)

I believe what you're missing is the registration of the constructor so that AngelScript knows that the Point class can be instantiated with Point(1,1). 

Learning from examples is probably easier. So just as I said in my e-mail I suggest you take a look at how the Complex class in the script math add-on is registered. Except a few semantic differences the Complex class is probably pretty much identical to your Point class.
