Basically im trying to make a sword with a ability when u right click and I need help

if you have a class for your sword that extends SwordItem just override the methos use:

	@Override
	public InteractionResultHolder<ItemStack> use(Level level, Player player, InteractionHand hand) {
		System.err.println("use hand=" + hand);
		return super.use(level, player, hand);
	}

else you can use events in MinecraftForge.EVENT_BUS: 

	@SubscribeEvent
	public void onLivingEntityUseItemEventStart(RightClickItem event) {
		System.err.println("RightClickItem");
	}

	@SubscribeEvent
	public void onLivingEntityUseItemEventFinish(RightClickBlock event) {
		System.err.println("RightClickBlock");
	}

	@SubscribeEvent
	public void onLivingEntityUseItemEventStop(EntityInteract event) {
		System.err.println("EntityInteract");
	}

	@SubscribeEvent
	public void onLivingEntityUseItemEventTick(EntityInteractSpecific event) {
		System.err.println("EntityInteractSpecific");
	}

 

and how would I make it tell a ability to run
