Is it possible to make social interactions with XML tuning?

@RexZheng I made a post over there with my scripts: http://modthesims.info/showthread.php?t=591559

I'll post them here as well (well, I say "my scripts," but they were pretty much copy/paste with ID name changes).

Basically, I wanted to inject into the list you find in object_sim, the one for interactions that show up when you click on your sim (and don't require another sim to do them). I thought this was the right code for it, but something isn't working because the interaction simply doesn't show up. It only shows up if I use an XML override, i.e. editing object_sim directly and putting it in my package file.

(I hope I'm not intruding on your thread, pearlbh)


Injector (named "triplis_child_play_injector")

# Python function injection
# By scripthoge at ModTheSims
#
from functools import wraps
import inspect

# method calling injection
def inject(target_function, new_function):
    @wraps(target_function)
    def _inject(*args, **kwargs):
        return new_function(target_function, *args, **kwargs)
    return _inject

# decarator injection.
def inject_to(target_object, target_function_name):
    def _inject_to(new_function):
        target_function = getattr(target_object, target_function_name)
        setattr(target_object, target_function_name, inject(target_function, new_function))
        return new_function
    return _inject_to

def is_injectable(target_function, new_function):
    target_argspec = inspect.getargspec(target_function)
    new_argspec = inspect.getargspec(new_function)
    return len(target_argspec.args) == len(new_argspec.args) - 1
