Passing Object by Ref/Pointer
Author
Hi,
I'm reckon this question must be asked all the time! But I'm having trouble getting AS to do what i'd like it to do.
What I've got on My code side my game object class and my instances of the object
Now I don't want AS to create instances of the object class I'd like to be able to pass by reference or pointer (Is this possible?)
My goal is to be able to write AS the will update the GObject i.e.
So what would be helpful is a simple example of how to do this?
Thanks
I believe you want this: Register an uninstanciable reference object
Basically you need to do this:
By not registering the factory method AngelScript won't be able to instanciate any objects of the type.
If you don't want to implement reference counting for your GObject type (recommended, at least for debugging) then you can register the AddRef and Release behaviours using a dummy function that doesn't do anything.
Of course, then you won't know how many references AngelScript holds to your object.

Basically you need to do this:
engine->RegisterObjectType("GObject", 0, asOBJ_REF);engine->RegisterObjectBehaviour("GObject", asBEHAVE_ADDREF, "void f()", asMETHOD(GObject, AddRef), asCALL_THISCALL);engine->RegisterObjectBehaviour("GObject", asBEHAVE_RELEASE, "void f()", asMETHOD(GObject, Release), asCALL_THISCALL);By not registering the factory method AngelScript won't be able to instanciate any objects of the type.
If you don't want to implement reference counting for your GObject type (recommended, at least for debugging) then you can register the AddRef and Release behaviours using a dummy function that doesn't do anything.
void DummyFunc(void *) {}engine->RegisterObjectBehaviour("GObject", asBEHAVE_ADDREF, "void f()", asFUNCTION(DummyFunc), asCALL_CDECL_OBJLAST);engine->RegisterObjectBehaviour("GObject", asBEHAVE_RELEASE, "void f()", asFUNCTION(DummyFunc), asCALL_CDECL_OBJLAST);Of course, then you won't know how many references AngelScript holds to your object.
