Budschie's Morph Mod

This is a mod whose goal it is to recreate the experience of the more or less discontinued MetaMorphMod in the Minecraft version 1.17.1.

What can this mod do?

This mod has several features, such as following:

It implements a system where you can kill a mob and get its "soul", so-to-speak. You can collect that soul by just walking into it. Then, you can morph into that mob by pressing a key on your keyboard (just look in the config and search for "Budschie's Morph Mod Controls", you can find all controls there).
The mod has abilities for vanilla mobs: You can fly as a bat, you can shoot fire balls as a blaze, you can teleport as an enderman, etc. etc.
You can turn in any player that you've killed and whose soul you've collected.
There is a gamerule for keeping the morph inventory on death. It is set to true as a default value, but you can turn it off if you wish so.
If you are an admin on a server, you can blacklist certain mobs with "/morphblacklist add <morph to blacklist>". There are also a couple of other commands, for example /morph <entity to morph to>, /playermorph <player name to morph to> and /demorph. All of this commands require a permission level of 2 (the default op permission level), as they all ignore the blacklist.
You can fully customize which abilities belong to which morphs via data packs. A tutorial for this can be found below.

Tutorial for data pack creators

As already said above, you can take advantage of the data pack system that minecraft provides and you can ship abilities for entities in said data packs. Note: This guide is inspired by the more indepth-tutorial on the Minecraft Wiki: https://minecraft.fandom.com/wiki/Tutorials/Creating_a_data_pack. I'd recommend you checking it out if you have any problems.

First step: You need to create a folder anywhere (for example, you could create this folder on your desktop). Then, you need to go inside this folder and create a file named "pack.mcmeta" (it is important that the file extension is .mcmeta. Make sure that Windows displays file extensions, otherwise this will not work.) Then edit this file, and set this as a content:

{
  "pack": {
    "pack_format": 7,
    "description": "Tutorial Data Pack"
  }
}

Note: You can replace "Tutorial Data Pack" with your data pack name.

Second step: In the folder of your future data pack, create the folders "data", followed by a folder named "tutorial_datapack" (this of course is just an example, you can put any name in there), create yet another folder named "morph_abilities". Now you have the folder structure "data/tutorial_datapack/morph_abilities". After checking that, you can now finally proceed to the next, and most fun part.

Third step: You can now create an unlimited amount of .json files here (the name doesn't really matter), and you can set this as the content of those json files:

{
    "entity_type": "<insert mob id, an example would be minecraft:horse>",
    "grant":
    [
        "<put your first ability here>",
        "<second ability goes here>",
        "<put your third ability here>",
        "<you can add as many abilities as you like to this array>"
    ],
    "revoke":
    [
        "<put the ability ids that you want to remove here>"
    ]
}

A concrete example would be:

{
    "entity_type": "minecraft:iron_golem",
    "grant":
    [
        "bmorph:mob_attack",
        "bmorph:yeet",
        "bmorph:slowness",
        "bmorph:no_knockback",
        "bmorph:more_damage"
    ],
    "revoke":
    [

    ]
}

Now, let's explain what's going on in the file above:

First, you have this JSON-string called "entity_type". It defines to which entity you assing these abilities. In this example, we are adding the abilities for the Iron Golem.
Now comes the JSON-array called "grant". In here, you can put a list of id's of abilities. I've chosen the abilities "bmorph:mob_attack" (which means that mobs will attack you if you are morphed), "bmorph:yeet" ("yeets" non-player enemies into the air), "bmorph:slowness" (which reduces your speed), "bmorph:no_knockback" (which removes knockback for you if you are morphed) and, last but not least, "bmorph:more_damage" (which simply increases your damage).
Now, we have yet another JSON-array called "revoke". You can revoke any abilities that were previously set with this JSON-array. If for example, I were to give dragons the ability to shoot webs, you could disallow this by putting this ability id in this JSON-array. So, it is just like "grant", but does the opposite.

Then, you can copy your data pack folder into the datapacks directory of your minecraft world. You can refer to this article on the Minecraft Wiki for more help: https://minecraft.fandom.com/wiki/Tutorials/Installing_a_data_pack.

If something doesn't work, look at the logs. If you have malformed JSON, or either your provided ability or your provided entity is not known, you should be informed in the logs by my mod.

Here is a list of all sample abilities (Is active ability => if you have to press a button for the ability to work):

OUTDATED!

Ability	Description	Ability ID	Is active ability?
BOOM!	The name explains it all. This ability allows you to explode.	bmorph:boom	Yes
Climbing	This ability allows you to climb like spider man.	bmorph:climbing	No
Cookie very yummy	Cookies are very yummy. Until you eat them. Do not try this at home!	bmorph:cookie_death	No
Eat Regeneration	Regenerates 4 HP when eating any food instantly.	bmorph:eat_regen	No
Egg Throwing	Some morphs have super powers, for example flying like batman and climbing like spiderman. And you... can throw eggs.	bmorph:egg_yeet	Yes
Enderman Teleportation	This ability allows you to teleport to a block that you are looking at in a radius of roughly 50 blocks. This ability has a cooldown of 40 ticks (2 seconds).	bmorph:enderman_teleport	Yes
Extreme Swiftness!	With this ability, your speed greatly increases	bmorph:extreme_swiftness	No
Blaze Fire	As the name suggests, this ability allows you to shoot blaze fire balls.	bmorph:fire_blaze	Yes
Ghast Fire	With this ability you can fire ghast fire balls. How original...	bmorph:fire_ghast	Yes
Fish Yeet	The name says it all. Good look trying to find the one mob in the game using this ability. JK you can't.	bmorph:fish_yeet	Yes
Flying	Flying is not enabled on this server.	bmorph:flying	No
Insta Climb	This ability allows you to instantly get on top of a block if you walk against it (much like if you were to walk on stairs).	bmorph:insta_jump	No
Jump Boost	This ability grants you a jump boost.	bmorph:jumpboost	No
Llama Spit™	You ever wanted to be a llama, eating grass, existing and spitting on people? Well, now you can with this ability.	bmorph:llama_spit	Yes
Mob Attack	This is probably the most confusing ability: If a morph has this ability, it will be attacked by any nearby hostile mob, like if you were unmorphed. If your morph doesn't have this ability however, you won't get attacked. So, to summarize: Having this ability => Getting attacked Not having this ability => NOT getting attacked So, it is essentially just like a backwards ability really.	bmorph:mob_attack	No
More Damage	This ability allows you to deal a total of 3 HP more of damage.	bmorph:more_damage	No
Nause on Hit	Title says it all really.	bmorph:nausea_on_hit	No
Night Vision	https://minecraft.fandom.com/wiki/Night_Vision	bmorph:night_vision	No
No Fall Damage	No Fall Damage.	bmorph:no_fall_damage	No
No Fire Damage.	No Fire Damage.	bmorph:no_fire_damage	No
No Knockback.	...	bmorph:no_knockback	No
Poison on hit	plz read the name of this ability.	bmorph:poison_on_hit	No
Slowfall	This ability grants you <insert effect>.	bmorph:slowfall	No
Slowness	This ability grants you <insert another effect>.	bmorph:slowness	No
Squid Boost	This is an exciting ability. The Squid Boost is a ability that helps you to immerse yourself in the daily life of a squid. It allows you to boost yourself into the direction you are looking, whilst at the same time applies a blindness effect to any nearby player.	bmorph:squid_boost	Yes
Swiftness	Like the Extreme Swiftness effect, but worse.	bmorph:swiftness	No
Water Breathing	Simply Water Breathing.	bmorph:water_breathing	No
Water Dislike	This ability makes sure that Endermen will be damaged by water.	bmorph:water_dislike	No
Water Sanic	If you have this ability, you will be granted the extreme power of Water Sanic.	bmorph:water_sanic	No
Web Passthrough	The name might suggest that this could be used for easily navigating through webs, but in reality, this is just a buggy mess.	bmorph:web_passthrough	No
Web Yeet	You can use this ability to farm cobweb/strings. As the name suggets, you can yeet webs with this ability. But beware, as this might expose you to an extreme level of spider ASMR.	bmorph:web_yeet	Yes
Wither on Hit	Yet another self-explanatory effect-on-hit thingy.	bmorph:wither_on_hit	No
YEET!	Last but not least, we have the YEET!-Ability. It allows you to yeet mobs into the air when attacking them. Sadly, yeeting players is not supported yet ;(	bmorph:yeet	No

So, that's it. Hopefully you've enjoyed this guide and could create a cool new data pack with abilities. If there are some issues on creating this data pack, feel free to post them as an issue on my Github page.
