Hello fellow simmers!
I would like to add more items for sale in the pets register, for example a litter box that is not available right now. Is this require of me to create a mod?
Thanks in advance for your help

This can be done with an XML tuning mod.
It's in the Register XML in GameplayData - though the usefulness of those directions will vary depending on your experience with tuning.

I don't have any experience. Do you think that it will be hard for a beginner?

you need to add these lines

<PetStore>
<GameObjectName>litterBoxCheap</GameObjectName>
<CodeVersion>EP5</CodeVersion>
<Category>Cats</Category>
</PetStore>

et

<PetStore>
<GameObjectName>litterBoxUber</GameObjectName>
<CodeVersion>EP5</CodeVersion>
<Category>Cats</Category>
</PetStore>

Tuning mods are the simplest sort.

This tutorial should cover the basics. All I have to add that it misses out is that you can search in GameplayData by using a filter. Type 'register' into the Name textbox, click the checkmark, 'Set', then tick 'Filter active' - all located on the bottom bar of S3PE. This will narrow down the visible results to only those with Register in the name.

Take care not to directly modify anything in GameplayData.
Find the resource simply named Register, right-click it and Export > To package and make your changes to that package instead.

As above, you'll want to open the XML in a text editor, scroll down to the PetStore section, and add the relevant lines. Double check that all <></> brackets are intact, that's probably the easiest way to accidentally break it. Save, install to your Mods > Packages folder.

I read the instructions of the tutorial but is not working. Could it be because the pet register in my game is a cc object and not from ea store?



Thanks for the tip!


Here's what I did.

First created a new folder and copy-paste there the GameplayData file.
Then I open it with s3pe.
Found the register.xml right click and export it to a new package.
Save it and opened it again with s3pe.
The only file it has is in it is the register xml which I edited with the notepad.
Than copy pasted the line

<PetStore>
<GameObjectName>scratchingPost</GameObjectName>
<CodeVersion>EP5</CodeVersion>
<Category>Cats</Category>
</PetStore>

and replace the scratchingPost with name I found with Nraas Debug Enabler, the who am I command.

<PetStore>
<GameObjectName>litterBoxCheap</GameObjectName>
<CodeVersion>EP5</CodeVersion>
<Category>Cats</Category>
</PetStore>

Saved the files as I read in the instructions
Copy and pasted the file into my mods folder.

A couple of things to test

A) Put the package you made into the Mods > Overrides folder and test if it works. If it does, you already have a mod that affects the Register XML installed and it was conflicting.
B) Delete the register in-game and place it down again, check again.

If the register is using EA's script, it should work. If it's a custom register script, then it will not.
