For now, the only way to become a werewolf is being killed by a
Wolf... because of that, this datapack is NOT for Extreme Mode

Alternatively, you can use the following command

---> /tag @s add werewolf <---

*There is a rare chance of instantly "die" after a transformation,
i don't know why happen that, it look's that is a problem with the
"attribute" command, i will see how to solve it later

*Because of the previous bug the rule "doInmediateRespawn" is on true
so if you die because of something (like a creeper) you will respawn
inmediatly, skipping the death screen

*Also, there is another bug related with the death, if you die during
a transformation you will lost the extra hearts and effects, BUT the
"wolf clock" will not stop, so after a while you will "unstranformed"

*The datapack was created and tested with Minecraft 1.16.1
Singleplayer, i DON'T know if the datapack works on other versions or
in multiplayer, BUT it should be compatible from Minecraft 1.15
to Minecraft 1.17 Snapshots, multiplayer should also work

That's are all the bugs, if you find one tell me please!

It's simple... after you being killed by a wolf you will get "sick"
and after almost 10 minutes you will become a werewolf... but that
is not forever, that is just a temporary transformation, after
become human again, you will get a Weakness effect, when the weakness
effect get to 0 you can transform again by look up while you are
sneaking, the transformation is 300 seconds long (5 minutes) you will
have a resistance effect of 5 minutes and another effects like jump
boost and speed with infinite time, the resistance will show you how
many time you have before becoming human again, becoming human will
give you Hunger, Slowness and Wither Effect, so be careful

*If you have an idea of something that i can add for this awesome
datapack, tell me down in the comments section, i will accept ideas
that make the datapack more interesting and amazing
