Is it possible to make social interactions with XML tuning?

I don't know how to even make interactions yet. Our custom traits do come with an interaction XML file, but I don't know how to actually make an XML interaction, let alone python. I think the first thing I'm going to have to do is find a basic beginners python tutorial, them find a tutorial specifically for the Sims 4 and specifically for adding custom interactions (the latter DOES exist on MTS, but I think a general python tutorial is probably necessary first.)

It has something to do with using python scripts to inject the interaction into a list, rather than manually adding it to the game's XML file and using that edited file as an override. Problem is, I'm so far having trouble getting an injection to work, myself. The override method is working for me fine, but that method creates incompatibility problems.

I can explain about these lists a little bit (at least, on the XML end), but I feel rather out of my element on the subject since I haven't gotten an actual injection working yet.

I think you can look at this post on MTS, I read the post and now I can inject interactions to the game.

I cannot post links now, but you cna go to MTS and see the modding discussion section, the first post is really helpful.

@Triplis I have successfully injected interactions, what problems did you encounter?

@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

Other file (I don't know what you'd call it... the thing that calls the injector)

    affordance_manager = services.affordance_manager()
    for sa_id in Triplis_Child_Play_sa_instance_ids:
        tuning_class = affordance_manager.get(sa_id)
        if not tuning_class is None:
            sa_list.append(tuning_class)
    self._super_affordances = self._super_affordances + tuple(sa_list)

@Triplis Mmm...Yeah your Python lines seems correct, how did you compile them? Maybe it's a process during the compilation that was wrong?
And, I'm not sure about it, but you could try if you add these lines?
import objects.game_object
or
import sims4.resources

I know the first line is used when we inject interactions to an object, but the game considers a Sim an object so maybe we should add that?
Not quit sure, though.

@RexZheng Thanks for the help! I just tried adding those and nothing, unfortunately.

Now that you mention compiling though, I wonder, does the game have issues reading scripts if they are .py, rather than .pyo? I was under the impression that .pyo is for performance, so I've been doing testing in .py and figured I'd compile later, but now I'm wondering if it's something as boneheaded simple as that.

Also, I just tried compiling to see if that would get any different results and got this error when I tried to compile the second file:

"ImportError: No module named services"

I can only assume it's referring to the line "import services" and if it's getting an error on the first line, I don't know if it's even compiling that file at all, even though it did spit out a .pyo file anyway, which I tried along with the other one compiled and still no results in-game. I've no idea why it's giving that error though.

Edit: I tried decompiling the file I compiled that got the error and it's all there, intact, so I guess the error didn't actually cause any problems. Which unfortunately puts me back at square one, as the scripts still aren't making the interaction show, compiled or no.

@Triplis I think you need a .pyo file for the game to read it!
As for "ImportError: No module named services", I encounter it every time and it seems that it just doesn't matter. My scripts are working fine but it shows up every time!
And...did you zipped those files with the injector? And when I fist made script mods, the WinRAR sometimes create a subfolder inside the zip file, making the game unable to read it.
Hope this helps!

@RexZheng Thanks! I made sure they are all compiled now. I think with your help I'm steadily narrowing this down.

I realized now that I'm getting a lastexception error file concerning my scripts when the game tries to load them. Says: ZipImportError: can't find module 'my_script_name' for both scripts.

I can only assume there's some weirdness with how I'm zipping files that it isn't happy about. Usually what I do is select both at the same time, then right-click and send-to-compressed-zip-folder. They are then both in that zip folder together, which I'm pretty sure is how it should be.

Anyway, I need to sleep now. Maybe it will make more sense with some rest.

@Triplis
You can use .py but the files need to be in a /Testing/Scripts/ folder. It's very convenient when you're testing your scripts because you don't have to recompile each time so it saves time.

@pearlbh
I've been using the same method as Triplis too : create a XML interaction, and inject it with Python. You can take a look here for some explanation : http://modthesims.info/t/546901 by Scumbumbo with a more in-depth explanation about injection by Deaderpool on post 36. It may be the thread RexZheng was talking about but couldn't link, because it's a really helpul thread. :)
