I'm trying to pass a handle of a game object to a script function, but its not working properly.

CScriptAny *Object::GetScriptObject()
{
	CScriptAny *n = new CScriptAny( scriptManager->GetEngine());
	int typeId = scriptManager->GetEngine()->GetTypeIdByDecl("Base_Object_IMP@");
	n->Store( pScrObj, typeId);

	return n;
}

Base_Object_IMP is the interface that the parent class of all scripted game objects, Base_Object inherit. Each instance store a asIScriptObject returned from the constructor. The function above fails with an access violation and it doesn't seem to be able to find the type id for 'Base_Object'.

I'm trying to cast from the base type to a another child type, like so:

Base_Object @base = null;
Object @obj = find_instance( objPlayer, Player);

if (obj != null)
	obj.GetScriptObject().retrieve( @base);

objPlayer_controller @PlayerHandle = cast<objPlayer_controller>( @base);
 

This is what I'm trying to do:

asIScriptObject -> Base_Object_IMP@ -> Base_Object@ -> objPlayer_controller@ (or any other child type).

Is there a proper way to do this?

I found that I could do the following:

asIScriptObject *Object::GetScriptObject()
{
	/*CScriptAny *n = new CScriptAny( scriptManager->GetEngine());
	int typeId = scriptManager->GetEngine()->GetTypeIdByDecl( "Base_Object_IMP@");
	n->Store( pScrObj, typeId);

	return n;*/

	pScrObj->AddRef();//<----- Crashes without calling AddRef
	return pScrObj;
}

and then cast like so:

int id = create_instance( x+(LogWidth*i), y, objBridgeNode);
objBridgeNode_controller @node;
Object @obj = get_instance( id);

if (obj != null)
	@node = cast<objBridgeNode_controller>( @obj.GetScriptObject());

Now the problem is the frame rate slowly drops. What could be causing this to happen?

I solved that frame rate problem. My debug output window was filling up with "accessing null pointer" errors. Now I'm checking for null pointers before I try to access:

for (int i = 0; i < NumLogs; ++i)
{
	int id = create_instance( x+(LogWidth*i), y, objBridgeNode);
	objBridgeNode_controller @node;
	Object @obj = get_instance( id);

	if (obj != null)
		@node = cast<objBridgeNode_controller>( @obj.GetScriptObject());
	else
		continue;
	
	if (node == null)
		continue;

	node.ParentBridge = GetId();
	node.Id = i;
	
	Nodes = id;
}

Apparently, I'm getting null pointers every time as if the cast operator does not know what type the returned asIScriptObject really is.

Even this doesn't work:

Base_Object_IMP @base = null;

base = cast<Base_Object_IMP>( @obj.GetScriptObject());

The result is still null. I know asIScriptObject being passed is valid before hand, so what can this problem be?

Edit:

Here's my other Base_Object class if it helps:

class Base_Object : Base_Object_IMP
{
//========== Constructor / Destructor ===========
	Base_Object( Object @obj)
	{
		@this.object = obj;
		x = object.x;
		y = object.y;
		sprite_index = -1;
		mask_index = -1;
		image_index = object.image_index;
		depth = object.depth;
	}

	{
		return object.PlaceMeetingDepth( mX, mY, type, depth);
	}
	
	Base_Object @object_place( float mX, float mY, int type)
	{
		Base_Object @base = null;
		Object @obj = object.ObjectPlace( mX, mY, type);
		
		if (obj == null)
			return null;
		else
			//obj.GetScriptObject().retrieve( @base);
			@base = cast<Base_Object>(@obj.GetScriptObject());
			
		return base;
	}


//========== Misc ===========
	uint GetId()
	{
		return object.GetId();
	}

	void SetRect( int l, int t, int w, int h)
	{
		object.general_rect.left = l;
		object.general_rect.top = t;
		object.general_rect.right = l+w;
		object.general_rect.bottom = t+h;
	}
	
//======= Variables =========
	Object @object;
	float x;
	float y;
	int sprite_index;
	int mask_index;
	int image_index;
	int depth;
}

classes are declared like:

objBridge_controller : Base_Object

{

....

}

That just might solve it. I currently using #include in each script to define Base_Object. Using shared makes a lot more sense.

EDIT:

That fixed it. Thanks!
