About
This mod gives some mobs a simple jumping ai that allows them to jump over obstacles and gaps in their way.
The mobs that currently have the jumping ability are Zombies, Zombie Villagers, Zombified Piglins, Silverfish, Endermites, Endermen, Wither Skeletons, Skeletons, Spiders, Cave Spiders, Illagers, Witches, Iron Golems, and Creepers.
The AI attempts to be realistic to vanilla jumping, which means that slow mobs can't jump very far. (Zombies can only jump one block for example).
Limitations
The ai does not do additional pathfinding, so it can't calculate a complicated series of jumps. Also, the ai starts to fail under very fast mob speeds or high jumps.
Configuration
The config file uses JSON. Add a mob by listing its id, and a priority. You can find mob ids by using the /summon command - the list of arguments will be a list of mob ids. The priority is a bit jenky. It represents what priority the AI has over other AIs. A lower value means that the jumping AI probably won't be overridden, but it might override other AI's. Unfortunately, the most certain way to gauge this is to look at the entity source code, but setting a low priority should in most cases be totally fine.
Installation
This is a regular Fabric mod, except that Fabric Kotlin is required.

FAQ
Can you port this mod to Forge or an older Minecraft version?
- I will not, but anyone else may do so.
Made for Fabric Modfest 1.16.
Yo is there a forge version?
need on server and client?
In reply to JoniDippinSauce:
It should work fine if it is just on the server
1.12.2 forge please? :))
my friends before getting this mod: hehe mobs are so stupid
my friends after getting this mod: SOMEBODY HELP ME I AM GOING TO DIE
Can you update this to 1.16.5?
In reply to Slimation:
Yes, just did a quick test. The current jar works fine, and I updated the versions for this page.

Cheers
Do you know of anyone that is planning to port this to forge?
In reply to hebiebe2033:
Yes I would love this to be ported to forge!
In reply to FluffyySnow:
Please do!! Let me know when!
In reply to FluffyySnow:
Are you saying you know someone who's doing it? If so, i'd love to hear more about it!
This mod is such a great idea to add more difficulty. Unfortunately, I'm a forge user but thanks for creating this mod anyway!!
This is so underrated that it hurts, keep up the good work.
Hi there! Is there anyone who has a Forge version on 1.16.3 that is ok with me putting it in a modpack? Thanks!
sorry to ask this but how did you achieve this behavior? I need it for one of my mod's mobs.
In reply to lilypuree:
The main functionality uses Minecraft's AI system if you are familiar with that. The actual algorithm is sort of complicated, but it primarily works with physics, raycasting, and Minecraft's pathfinding system. If you want to code it's located in this repo: https://github.com/miyo6032/maelstrom-library. Note that it is written in Kotlin and uses a handful of library utilities as well.
Is there any chance you can make it so the mobs incorporate the parkour into their pathfinding so they won't crowd below you if there is a small simple way up that includes the parkour? Also, is there any chance you can add a config to change how far mobs can jump and how high? Also, last thing, sorry, you forgot to add pathfinding for piglins, piglin brutes, etc.
Other than that, INCREDIBLE mod, plus, the fact that it is server side makes it SO much better! I love this! Incredible job!
In reply to NumberOneRiker:
It is difficult to incorporate anything into minecraft's pathfinding. I have considered it before. I do intend to add some more configuration, but I don't know for sure or when that might happen. You can add pathfinding to piglins in the config - the reason I refrained by default is because Minecraft does something a bit different with the AI of those mobs and I haven't had the time to test if my AI would work in all cases for them. Happy you enjoy it!

Makes sense! I had just hosted an event with over 70 people on a server using this mod server-side for 1k$. People freaked out when they saw mobs jumping over gaps towards them. It was incredible, please keep up the incredible work!
