I apologize for being this late to update my script, but this is a big update and I think the new features are worth it!
• Added support for 1.16:
[+] Added the new mobs: Strider, Hoglin, Piglin & ZombifiedPiglin
• Other major changes:
[+] The player now faces the right direction when he comes in visible range and when he remove his disguise
[+] The player's held item is now properly shown to other player when disguising(in a compatible mob, for example Zombies)/coming into visible range
[+] Added an experimental feature, which show the stuff of the player to other players in 1.12 or below (not only the held item)
• Minor changes:
[+] Added an alert if ProtocolLib or ThatPacketAddon is missing
[+] Functions were updated (I hope I didn't forget anything)
[~] The mobs are now in alphabetical order (at least in the options)
[~] I optimized the script (it still isn't perfect, but it's not horrible)
[~] The mobs are now in alphabetical order (at least in the options)
[~] Some errors messages are now sent to the ops
[+] Added a MobToId function for 1.16 & a UpdateHand function for 1.16 too
[+] Added return for functions if the mob was deleted from minecraft (Pigmen in 1.16). MobToId("ZombiePigman") return -6 if the mob doesn't exist anymore
[+] Added options to disable all the new features (they're all true by default)
[-] Removed all the useless return in some functions
