Method overloading in Angelscript
Author
I noticed the other day Angelscript supports method/function overloading now. I have this working with two methods in my C++ code SetView and SetView2 both exposed as SetView in Angelscript. Is there any way to expose overloaded methods to Angelscript (e.g. if both methods in C++ were called SetView)?
If I try this using asMETHOD(CCamera::SetView) for both methods then my compiler doesnt know which method I mean. Is there any syntax to tell the compiler which method I mean?
Thanks
Joe
You'll have to let the compiler know which method you mean by casting the pointer to the right type.

Okay that is pointing me in the right dirrection; I was only familiar with the syntax for function pointers, not methods. But it still doesnt work.
I'm using Visual Studio.NET 2003, and the C++ compiler is coughing up an error with that syntax:
Any suggestions? What compiler are you using?

Sorry about that.
I think the correct syntax is without the paranthesis:

Ok, that didnt work either, but it got me started; the correct syntax appears to be

engine->RegisterObjectMethod("CCamera", "void SetView(const VECTOR3& vPosition)", asMETHOD((void (CCamera::*)(const D3DXVECTOR3&))SetView), asCALL_THISCALL);engine->RegisterObjectMethod("CCamera", "void SetView(float x, float y, float z)", asMETHOD((void (CCamera::*)(float, float, float))SetView), asCALL_THISCALL); Thanks

Just as a reference for anyone else having this problem, using MSVC6 you need to use the following syntax:
asMETHOD((void (CCamera::*)(float, float, float))CCamera::SetView)
Note the extra CCamera towards the end.
