Important: To avoid issues, make a backup of your world before adding this mod

Magnifying Glass

The mod adds a magnifying glass (found in the Tools & Utilities tab).

Right-click animal with magnifying glass in any hand – shows gender + sterile status.
In offhand – shows icons above scanned animals within radius.
In main hand – shows icon only when aiming at a scanned mob.

Settings

maleChance – chance for male gender in % (default 45)
femaleChance – chance for female gender in % (default 45)
displayRadius – radius for displaying icons in blocks (default 24)
allowMaleMaleBreed – allow male + male breeding (default false)
allowFemaleFemaleBreed – allow female + female breeding (default false)
allowSterileBreed – allow sterile animals to breed (default false)
enableVillagers – enable gender system for villagers (default true)
keepVillagerGender – preserve villager gender when turning into zombie and back (default true)
enabledMobs – list of mobs affected by the mod. You can add any mob by its ID

Sterile chance is calculated automatically. By default 45% male and 45% female — the remaining 10% is split equally: 5% of males will be sterile and 5% of females will be sterile. If you set 50% male and 50% female — there will be no chance for sterility, and mobs will not receive sterility.

FAQ

Will there be a port to Fabric / NeoForge / other versions?

Not for now. The mod is made for Forge 1.20.1. If the mod becomes popular and I have the opportunity, I will try to port it to other loaders and versions.

Can I use this mod in my modpack?

Yes, you can freely use this mod in any modpack. The only thing – if you have modded animals in your pack, you will need to add them manually to the config (enabledMobs), otherwise they will not receive genders.
