The Blood Moon is a gameplay feature I originally put together for HoneyCraft SMP, but have reworked to work on it's own in vanilla worlds! Blood Moons also bring more immersion and atmosphere and makes survival hinge on players being aware of the movement of the heavens above!
How it works:
- Blood Moons replace full moons, and as such occur once every eight in-game nights.
- When a Blood Moon rises, an increased number of monsters will spawn; including monsters that usually do not spawn in the Overworld!
It really makes the flow of time/movements of the moon feel more impactful as survival can depend on not getting caught out during a Blood Moon! This addon also includes Fireflies, like those seen in CS_Fireflies. Unfortunately you can't query the moon_phase in spawn_rules, so I had to use a separate mob to serve as a proxy spawner for blood moon mobs.. I'm sure you'll love the depth and atmosphere the fireflies will bring to your nights!
What it spawns:
- Fireflies will spawn every night in most biomes. They are harmless and make nightscapes more beautiful! They can be killed for 1xp and sometimes 1 glowstone dust.
During Blood Moons:
- More Zombies. ... common
- More Skeletons. ... common
- Witches. ... rare
- Blazes. ... rare
- Withered Skeletons. ... uncommon
- Phantoms. ... rare
- Slime. ... very rare
How to customize:
If you want to add/remove your own mobs to the Blood Moon spawn list, be my guest!!
Fortunately, this is a pretty simple addon so it should be pretty easy for folks to edit, assuming you have a basic understanding of json syntax!
Simply open up behavior_packs/CS_BloodMoon/entities/fireflies.json ...
In the area noted as 'Blood Moon stuff !!' at the top (see pic above) you can add or remove mobs to/from the blood moon spawn list. Just copy+paste one of the "minecraft:blood_moon_blah" components and add for a mob you'd like to add, or find the label for the mob you want to remove and remove it. Mind your commas!
Then, after that scroll down towards the bottom of the same file to where you see the next 'Blood Moon stuff !!' comment...
Here, do the same thing you did above, but with the a copy+paste of one of the components like highlighted above. To explain "weight" easily, it determines how likely/often each mob is to spawn. A higher number relative to existing numbers makes the mob more likely to spawn.
After that, simply save the file and load up your world! Super easy!

Installation
- Install as you would any other addon!
- If you use shaders that replace the moon texture, put this pack above it or the blood moon won't show.
--- if you use shaders that use code generated moons, the blood moon won't show at night at all.
- Enjoy and report all problems in the comments! c:

And also blaze and wither should not spawn during the blood moon, only overworld hostile mobs. Cause i already have 5 wither skeleton head and some blaze rod without even search and explore the nether to find a nether Fortress which is very rare after the nether update
I will tell you that your the creator of this mod plz.
I'm aware of the bug where zombies spawned during blood moons are having crazy fast movement speeds. I'll have that fixed and I've also decided i'm going to go ahead and start overhauling the difficulty of the game and mobs with this addon. I'm thinking of improving ambience as well as some monster behaviors.
We'll see what happens. c:
Thank you and glad you enjoy the addon!
I'm sorry to hear that though! What exactly seems to be the issue you're having?
Thanks for checking it out and i'm glad you enjoy it!
I actually am working on an update for the firefly library which allows players to catch them in bottles and also introduces new colors for them. Defining genders could be interesting.. we'll see!! c:

You're perfectly welcome to add your own mobs, or even include mobs from other addons if you'd like.
If you want to have a more difficult Blood Moon without editing anything, I suggest trying out HurtMePlenty( https://mcpedl.com/hurt-me-plenty-addon/ ), as it goes quite well with the Blood Moon! c:
To my knowledge, it is not possible to randomize or edit the moon's cycle. Perhaps in a future update we'll get that capability, but unfortunately it's not an option atm.
Enjoy!
Keep it up man, i love you?
