R.A.W. Shadows

First open beta of my first MCreator-free mod ! I said MCreator-free

• Added four Shadow creatures to the game, based on the Aventures de la R.A.W. roleplay system and universe.

• Shadows have custom behaviours with swimming depending on the position of their target in or out of water.
• Shadows emmit a custom particle called "Shadow Spark" that you can have fun with using commands.
• Another custom behaviour is with daylight. They are more scared of light than undead mobs and will vanish in full daylight, so they flee the Sun even when hidden under something, wich makes them less prone to stroll into their death sentence.
• A planned future behaviour (not yet added to the beta) allows Shadow Zombies to ride Shadow Cows, giving them a horse-like speed boost and giving them incredible style. 

• Added compatibility with Xaero's Minimaps icons since the mod is meant for a modpack using that minimap mod.

know issues :

The Primary Shadow might do some silly dashes into the void since they can spawn in the End Islands. I know I said they were "smart" but well, everyone has some off days.

In addition to that, I still need to fix the Primary Shadow's walking animation. It's meant to hover with joined hands but right now that doesn't happen. I might also change the idle pose because I'm not sure that the angle I chose for the arms looks the most minecraft-like. All in all, that shouldn't ruin the immersion.
