I know, it's a long shot, given how messily the App file creates things. Still, it's worth asking: has anyone figured out a way to create a class that inherits from a class in App?

Have not tried, but shouldn't be a problem, why?

Shouldn't be impossible, though be carefull when you do.
For one thing, some functions can call exported functions from the exe side of things.

Well, say you're trying to create a new class, called MyShipClass, which inherits from App.ShipClass. The class itself is written easily enough, but then how do you actually create the ships in the game?

According to loadspacehelper, you call App.ShipClass_Create(). So, instead, you make a function called MyShipClass_Create().

Unfortunately, here is the App.ShipClass_Create() function:

Code:

def ShipClass_Create(*args, **kwargs):     val = apply(Appc.ShipClass_Create,args,kwargs)     if val: val = ShipClassPtr(val)     return val

Certainly, you can make a class called MyShipClassPtr, so that call can go through, but how can you create an Appc.MyShipClass_Create()? As far as I can tell, you can't, and, as far as I can tell, the only way to create a game object is by going through Appc. Hence my problem.

If I've overlooked something, I'd be very pleased. Thanks, guys.

I think you got your brain waves wrong, don't think of the classes in App.py as the actual classes, but as shadows of the actual classes, or portals to the real objects.

I got a question for you, what functionality are you trying to specialize?

Or I'm still a n00b programmer who shouldn't mess around with what he doesn't understand.

It's okay; I got ArmadaShipClass(App.ShipClass) working. The problem was not in creating the objects. In fact, the objects were creating fine. I was using the MissionLib GetPlayer() function to *get* the objects, though, and the Appc function was--I think--grabbing the parent class instance instead of the child's. In any case, once I wrote my own GetPlayer() function, everything cleared up, and I was free to add and overwrite methods as I saw fit.

Thanks.

As I understand it, he's trying to override the App ship class so that he can add custom functions to it for whatever nefarious purpose he requires... There are probably other ways to do whatever he's trying to do, but if this works, more power to him. I can see there possibly being problems later on, if he plans on storing data in his custom ship class, though...

uhm ok.
How about App.ShipClass.DoSomethingCoolFunction = MyFunction?

Else I believe a 'has a' version would be cleaner as the 'is a' relation here.

I have to agree with SimRex here.

The problem I forsee is the following:
You create a new ArmadaShipClass object, do something with it, and wait for an event to happen.

When that event happens you happily get the ArmadaShipClass object, but then. Since the classes in App.py are nothing but shadows of the real thing, your actions you did before won't be present in your just obtained ArmadaShipClass object.

To counter that effect, you would basicly create another <Insert your Foundation Technologies-like script>.

All sound advice, which I will bear in mind when my code blows up on me (as it ineveitably will).

Looking at App as a "shadow" has indeed helped, at least in understanding what I'm reading.

I'll be out of town for a couple of days, experimenting with this.
