Hostile Creatures Expanded

Dependancy: geckolib

This is my first mob mod I personally made it for my modpack fortuna rpg, and cause I wanted to see if I could be able to make a creature mod keep in mind I am very beginner in mod creature since I used mcreator for this mod, in the next update on my modpack Ill include this mod with magicnpc to make them even more special to fight. ATM I don't know how to add config files for spawn wieghts and biomes, if you know how to do that please let me know in the comments, I asked around discord help forum but gotten no response. Also I wanted grumble mob to be able to fly but I did not know how to restrict the hieght it flies cause when I made it fly when testing was floating very far away like ghast and I intend it to fly shorter distance. stone Golem will only fight you if attacked and gives a lot of xp when killed. Most of them will spawn only 1 at the same place.
spawns below:
brown scorpion (spawn weight: 70): dripstone and lush caves, desert, badlands, savanna

stone golem (spawn weight: 50): dripstone cave, stony peaks, all windswept biomes

dimetrodon (spawn weight: 60): most overworld biomes (maybe will spawn in caves)

grumble (spawn weight: 50) (aggro/range attack: 14 blocks): all snowy biomes, End biomes

chiraptor (spawn weight:65): most forest biomes, all jungle biomes, plains, sunflower plains
