I was trying to figure out how to override a function that an object calls without having to make a clone of that object and derive it and then use override. Specifically I wanted to make any and all computers (which is key because I know I could make a copy of all of the objk files and then change it to the proper script but it wouldn't include any custom content computers) use a different version of the IsComputerUsable method (without core modding of course). Does anyone have any light on the subject?

Thanks

Well I am guessing you write your script calling it the same thing and stick it in the mods folder. If resource.cfg gives the folder contents high priority, it should override. But you probably also have to give it the same resource number, which means you have to include everything that was originally under that instance number. What exactly is the definition of a core mod? This sounds like it.

Well I consider a core mod one to be where you edit the actual main scripts for the game and then insert the new one which overrides the original. For core mods they conflict with each other because there would only be four files (or so) to edit. Would calling it the same thing and have like proper namespaces and classes to actually get it in the right spot actually work? I'm not really sure what you refer to as the same resource number unless you are referring to going into core modding which would take all of the Sims3GamePlay files to get to the part of just the computer.

In ani_'s "Get Drunk" mod it alters all of the bar objects with a new function. You might want to ask them

I'll take a look at it, but Is the new function overriding an old one t hough?

It appears so. Or ani_ removed the old one.

So i'm not really sure what you are referring to for which function it is overriding. It just looks like ani_ adds new interactions.

In short: You cannot, not without a core mod. You can't even override the IsComputerUsable() method if you derive a new class from Computer, because the method isn't virtual.

There is a non-core way, though. The IsComputerUsable() method gets only called by interactions. You could clone all these interactions and change their Test() methods to call a different method. Then you remove all the original interactions from all computers (and use a listener to handle new computers) and add your changed interactions. Of course this will have no effect, if other code instantiates the original interactions directly.

Well considering there are 45 different calls of the IsComputerUsable() method that would still take some time. But maybe if I clarify myself more it might make more sense/another way. I don't want to change or remove anything that is already there I only want to add my own checks into it.

That is the price for doing it non-core. A lot of things that are just minor changes for a core mod become very difficult if you want to do it non-core.

That doesn't matter, really. A change is a change is a change, and you can only change code with core mods.

While a change is a change sometimes it would seem easier to be able to add something then to edit the already existing one.

I don't override anything. I copied the code for the make drinks interaction for example, and made my own version of it so I could insert the code I needed inside the original make drink interaction. Then just removed the original from the object (which by the way I'm doing wrongly in the drunk mod, it's better to do it in the ITUN file, instead of the code).

And speaking of ITUN files. If you only want to add a check when an object is usable, can't you achieve that by modifying the original ITUN of the interaction you are using?

There is a section in there called

Where you can add different kinds of checks, like what age groups can use it, or is it allowed for pregnant people or not.

And why is that? I'd prefer doing something like that in code anytime. Changing the original ITUN resource results in a tuning mod. Tuning mods can conflict with other mods; scripting mods are virtually incapable of conflicting with any other mod. Plus, removing a whole interaction from an object saves a bit of processing time in comparison to a changed tuning which just makes the test method of that interaction return false.

Because I noticed that just removing the interaction from the object, will not stop Sim's from using them. The coffee mod for example, the original "Serve Hot Beverage" interaction was removed in code, I couldn't see it if I clicked the coffee machine, but sims would still be able to use it. Changing the ITUN file I was able to both remove it from the object, and stop Sim's from using it.

This same bug still exist in the drunk mod, sims will sometimes just drink juice, even thou the interaction is no longer in the object itself.

Something like that can happen if code "manually" instatiates an interaction instance and adds it to a sim's queue like in the MakeSimGoHome (or whatever) method.

I don't think that's the case for interactions like that, though. Might be because you derived some of the interactions instead of cloning them. Other code that just looks for the base class will access the original Singleton and not your new one.

I noticed that too. And it only happens on community lots.
