Accessing one scriptable object from another?

#1 Im looking for somthing like this in c++:

VideoCapture vc = ???::getObjectByName???("VidCapture");

Then i go:

MyDevice mydev = vc.getDevice();

#2 What I do usually, even thought it's a big hack is create a new variable for the object, which contains the ID of the associated object.

%Associated_Object = %Mainobject.associated_object;
%Associated_Object.variable or %Associated_Object.function(Bla, bla, bla);

Works fine, but it's a bit hackish.

#3 Thanks simon but im in c++ not script.

#4 You could write a ConsoleMethod for the VideoScreen class called 'setVidCapture' that takes a VidCapture object as a parameter, then inside that ConsoleMethod, use something like this to translate the object ID you'll be passing to the method into the actual object:

ConsoleMethod( VideoScreen, setVidCapture, void, 3, 3, "( VidCapture object)"
              "Set the VidCapture object for this VideoScreen")
{
    //argv[2] should contain the object instance name/id of the VidCapture object
     VidCapture *vc = dynamic_cast<VidCapture*>(Sim::findObject(argv[2]));

     //then do what you want to with the VidCapture instance.
     //an automatically declared variable named 'object' will contain your VideoScreen instance.
    
}

#5 Thanks Brian, looks exactly what i want.

#6 How do i go about setting setVidCapture?
My GUI VideoScreen is placed by the GUI editor and not script.

#7 I think you can just give it a name in the GUI editor, and reference it that way, ie.,:

(in the .gui file, it should look something like this)

new VideoScreen(MyVideoScreen) {
   //parameters, etc...
};

Then in script somewhere (such as in the GUI window's "onWake" method):

%VidCapture = new VideoCapture();
MyVideoScreen.setVidCapture(%VidCapture);

#8 I tried these 2 lines on it's own but it just crashes. any ideas?

VideoCapture *vc = dynamic_cast<VideoCapture*>(Sim::findObject("VidCapture"));
CVVidCapture* vidCap = vc->getDevice();

#9 When I use this line of code it's always null.

VideoCapture *vc = dynamic_cast<VideoCapture*>(Sim::findObject("VidCapture"));

Am i using it correctly?

#10 Hey Paul -

Basically the approach Brian outlined above is the right way to do this.

ie, instead of having C code searching for a script object of a particular name,
provide "setter" and "getter" methods in the object and use those explicitly from script.

the resulting code will be much more robust,
and it also sidesteps whatever issue it is you're having with findObject().

#11 Thanks brian & orion, ill look in to it more.

#12 Thanks all, I tried Brian's approach and it works nicely.
