Evoker Charm - Functions Datapack

Hence here is my first functions datapack!


This datapack adds a new item: the Evoker Charm!
This charm allows the player to cast evoker fang spells.

Attacks:
Ranged attack: By right-clicking with the charm on your main hand, the player will summon evoker fangs in a straight line. This spell will go through blocks and will last up to 30 blocks. This attack is fully directional, so the spell will be cast wherever the player is looking at. Fangs will always appear on the ground.
After using this attack, the player won't be able to cast another spell for 3 seconds.

Area attack: By shift + right-clicking with the charm on the main hand, the player will summon 4 circles of fangs around him, covering a radius of 5 blocks. The fangs will circle the player twice for 2 seconds, following his position if it moves. Fangs will always appear on the ground.
After using this attack, the player won't be able to cast another spell for 5 seconds.
