Further Description
This upload consists of two mods with the same intent: one for CAS and the other for in-world (live mode).
The CAS mod adds two name randomizer buttons to CAS: one for the first name and one for the last name, allowing the first name and the last name to be randomized separately.
The in-world mod replaces several interactions (or functions) so that the name input dialogs include a randomizer button to randomize the first name or the last name. These occur when naming or renaming Sims, pets, and imaginary dolls, and while adopting.
Changelog
18.13.2026
→ The one namespace of the script assemblies is now mod-specific (my name plus the mod's name), so that the namespace is unique to its mod; and the main classes are now separated into different classes based on functions.
→ CAS First Name and Last Name Randomizers is now better compatible with Tiny UI Fix! Normally, you would need to reinstall Tiny UI Fix after installing this mod, but it is no longer required if you install or uninstall this mod. You may still receive a runtime mismatch report from Tiny UI Fix, though.
→ Addon assemblies for In-World Name Randomizers, except for the Mono Patcher addon, will now conditionally load, currently that is, if you have NRaas Woohooer or NRaas Mover installed.
→ Unintentionally, the useMonoPatcher (now renamed to UseMonoPatcher) tunable was being ignored for function replacements; not anymore!
→ Some interactions overridden by NRaas Woohooer didn't have proper names in the pie menu and the interaction queue; not anymore!
→ The HarvestPlantSim interaction, when overridden by this mod, couldn't clone tunings from NRaas Woohooer's definition; not anymore!
→ An issue where null (empty, non-existing) interaction tunings are being registered to the interaction tuning dictionary is fixed.
20.10.2025
→ The mod is made compatible with NRaas Mover for adopted created SimBots.
18.10.2025
→ Due to a typo in the tunable file, interactions replaced by NRaas Woohooer were not getting replaced by this mod.
→ Name randomizer is now available for renaming imaginary dolls and buying horses!
16.9.2025
→ Some portions of the scripts have been rewritten. And the script assemblies have been built as "release" builds instead of "debug" builds.
→ CAS First Name and Last Name Randomizer is now renamed to CAS First Name and Last Name Randomizers.
→ First name and last name randomizer buttons will no longer be duplicated when you change a Sim's gender, age, occult, basic appearance, etc., while the CAS basics window is open.
→ In World First Name and Last Name Randomizer is now renamed to In-World Name Randomizers.
→ NRaasWoohooer First Name and Last Name Randomizer is now obsolete. All of its functions are now included within In-World Name Randomizers.
→ Mono Patcher is now supported, so that if you have it installed, instead of replacing some of the interactions, the mod will replace some functions (a.k.a. methods). This will also free this mod from NRaas Woohooer. You can, however, disable that from tunings.
→ Name randomizer is now available for adopted created SimBots, but not the ones from the My Best Friend lifetime reward.
→ In-World Name Randomizers now has three new tunables for modders in case of compatibility issues.
18.5.2025
→ An issue regarding alien pregnancy birth is fixed.
23.2.2025
→ The NRaasWoohooer addon is fixed to become functional as previously intended.
18.1.2025
→ The mods have been rewritten and renamed.
→ The replacement interactions now include two adoption interactions (for kids and pets).
→ There should now be a warning if the replaced interactions get replaced by another mod.
→ NRaas Woohooer compatibility mod is now separate from the actual mod. Otherwise, in the absence of NRaas Woohooer, the compatibility mod used to cause errors and affect other mods.
4.7.2023
→ The replaced interactions now have tunings of the original interactions. Before that, the interactions had no tunings; thus, they were run by Sims who were normally disallowed.
→ The mod is made compatible with NRaas Woohooer for real this time. Before that, the new interactions were based on the original interactions, not on NRaas Woohooer's interactions; thus, the mod was shadowing the effects of the conflicting interactions from NRaas Woohooer.

Tunables
ReplacingInteractionDefinitions → A list of the names of the interaction definitions to be replaced. Only the ones listed by default are applicable.
UseMonoPatcher → Whether to replace methods instead of some interactions. Only applicable when Mono Patcher is installed. Default: True
ReplacingMethods → A list of the names of the methods to be replaced. Only the ones listed by default are applicable and only when UseMonoPatcher is set to true.
Compatibility and Conflicts
These mods should not conflict with any other mods, as they are pure script mods, that is, except:
↳ If another mod is also modifying the original name randomizer button in CAS, or replacing the same interactions and functions.
→ NRaas Woohooer replaces a few of the interactions (births, specifically), but both mods are made compatible by an addon.
→ Same Zodiac for Twins and Triplets is not compatible, and only one of the mods will succeed in featuring its effects. However, Newborns Get Zodiac Signs that Match the Current Season is compatible as it does not replace any interaction.
→ Adoptable Teens replaces one of the interactions (kid adoption), but both mods are made compatible.
→ NRaas Mover replaces one of the interactions, but both mods are made compatible by an addon.
