Tuning - Give interaction a cost in simoleons

So from what I've encountered with drinks modding such as with the fountain & the wedding stories tea set, you should be able to add in payment via adding a "payment" snippet into the "basic_extras" tag (or create the basic_extras into your interaction tuning if it doesn't exist). For example:

<L n="basic_extras">
<V t="payment">
<U n="payment">
<V n="payment" t="literal">
<U n="literal">
<V n="payment_cost" t="amount">
<U n="amount">
<T n="amount">200</T>
</U>
</V>
</U>
</V>
</U>
</V>
</L>
For tuning examples where they've used it, take a look at say "fruitPunchFountain_FillWith_Cider".

That looks good so far 👍

For applying it, as long as you haven't modified the tuning Id (and name, but not sure if that has an effect), it should override the original tuning's behaviour I think. Just make sure the file that tuning's in is in your mods folder, ofc. Just give it a try in the game, there should be a price (§5) on the right of the interaction if it's working.

That's correct, presumably. Though, I would still try that first to make sure it works.

If/Once you want to apply this to a specific object rather than make it an override, that will become more involved.
Not only that, the WM (washing machine) utilises a state for whether it's been loaded with laundry, which will add extra steps.

To write out the steps you'll likely need to take, in your commercial WM mod package:
1. Make the 'wash clothes' interaction use a unique tuningId, so it doesn't override the original tuning.
2. If you don't already have it, add in the WM object tuning & make sure it also has a unique tuningId, and the WM's object definition adopts that tuningId as well.
3. Add in the object state tuning for the WM's full state. Specifically 'laundry_WashingMachine_Values_Capacity_Full' (175917). Also make its TuningId unique.
4. Inside your now-custom object state tuning for the WM's full state, replace the original wash clothes interaction value with your own one (the one from step 1).
5. Inside the custom WM object tuning, replace all instance of the WM's full state object state tuning (175917) with the new tuning you'd have generated from step 3.

If everything's done correctly, and this is all possible in the first place, then hopefully that should make your modded commercial washing machines now money-operated, whilst not affecting the consumer (nor any other) ones.

I'm assuming that you already know how to make the tuningId unique, but just holler if you need a short guide on that, or for any other steps.

So I tried this, I put the .xml file that I modified into the mods folder and it didn’t have any impact.

Ahh that makes sense. How would I bring this xml file into a .package file?

ed2: nope, I think I see now. I needed to create a new blank package and add “interaction tuning”, import the xml and save?

Yup, that's right. Either import the xml, or you can go to Tools > Export Tuning and search for the relevant tuning to add into the package.

So for my step 2, you'll want to open up your commercial WM package. I'm going to assume you've already cloned it properly, and it appears in the sims 4 BB catalogue without issue.

In the commercial WM package, I'll also assume that you don't have the washing machine object tuning in it yet (if you do, you can skip the following bit).
The object tuning is called "object_laundry_WashingMachine" (TuningId: 175587), so you'll either want to import the xml for that into the package, or go to Tools > Export Tuning to find & add it in.

Once the above is all fine, you'll want to do something similar to this for the WM's object tuning, so it generates a unique tuningId.


If you've added in the tuning via S4S (i.e. via Tools > Export Tuning), there would also be a "Sim Data" along with it. I'm not sure if it's important for the WM, but I'd still name it similarly & copy the Instance from the Object Tuning over into the Sim Data just in case (adding 'sprealty:' to the Sim Data's name won't regenerate the Instance like in Tunings, so you'll need to manually copy it over to be associated together).
