im making an origins plugin for a server and i need to improve some bugs.
one of which is the On Hand Item Swap event. it just wont work.
also ive tried everything to cancel fall damage for an origins plugin and i just keep having fall dmg

it would also be useful to know how to take dmg in water and how to have a cooldown on abilities
