Would it be possible to add compatibility with Better Safe Bed? That mod's developer says that he can't do that himself because of some mixins, perhaps it would be possible from your side?

Funnily enough, in the version I published earlier this week, I removed the redundant check, and replaced it with "Is the fail reason NOT_SAFE?". This is how it should've always been, but I didn't know how to properly mixin a lambda when I originally wrote the mod.

So in theory the latest version should already work together.

Edit: Though I am slightly confused about how their mod actually works. Like I know it does (just tried it), but looking at the vanilla code and his, I don't get what they're changing that the vanilla doesn't already does. In vanilla, it gets a list of only HostileEntites, so removing non-HostileEntities seems redundant and their checks if it's target is a player, but vanilla only includes the HostileEntity if it's angry at the player trying to sleep.

That's good to hear, I should have probably double-checked myself before creating this issue! 😅 Regarding the mixins, I also don't know what they do, let's wait for the dev's answer 🤷‍♂️
