FOSS gamedev and creative worlds

Like the name says, i want to place farm animals, and by that i mean more than a few without killing gameplay. Also dont want to play around with config files, or install giant modpacks containing creatures that dont really pass for animals as we know them.

Im talking, 3, maybe 4 animals, the most common ones: chickens or turkeys, cows, pigs. I dont need them to move around alot, or frequently, though i will pen them in :-)

Don't really have time to do this though if no one else does i will get around to it :-)

example farm:

You can use simple mobs. Go to the init.lua and delete all register_mob() calls except the sheep. Also remove every register_spawn call. Then copy the sheep definition to create the new animals.

All it takes with the animals (mobf)-modpack is to delete all the subdirectories which contain unrealistic animals. That also reduces the load a lot because those won't spawn at night and trying to figure out how to kill you. It has no pigs, but the rest is fine.
