Describe

When casting spells from Spell Engine, aiming mode does not activate

Reproduce

Steps to reproduce the behaviour:

1. Install any of the RPG series mods
2. Craft any spell book in the spell table and enchant it with spells
3. Use any staff to cast the spell
4. When moving while casting, the spell is going to target what is in front of the character instead of the camera

Expected behaviour

Aiming mode should activate while casting spells

Additional context

I tried looking for a way to add the NBT tag to a datapack so aiming mode activates while casting a spell, but couldn't find any tag on the items that can cast spells, so I think it needs a different way to know when a spell is being cast
